Data Sheet M19866EJ1V0DS 7 PD44164082A-A, 44164092A-A, 44164182A-A, 44164362A-A Pin Identification Symbol A0 A DQ0 to DQxx LD# R, W# BWx# NWx# K, K# C, C# 8 (1/2) Description Synchronous Address Inputs: These inputs are registered and must meet the setup and hold times around the rising edge of K. All transactions operate on a burst of two words (one clock period of bus activity). A0 is used as the lowest order address bit permitting a random starting address within the burst operation on x18 and x36 devices. These inputs are ignored when device is deselected, i.e., NOP (LD# = HIGH). Synchronous Data IOs: Input data must meet setup and hold times around the rising edges of K and K#. Output data is synchronized to the respective C and C# data clocks or to K and K# if C and C# are tied to HIGH. x8 device uses DQ0 to DQ7. x9 device uses DQ0 to DQ8. x18 device uses DQ0 to DQ17. x36 device uses DQ0 to DQ35. Synchronous Load: This input is brought LOW when a bus cycle sequence is to be defined. This definition includes address and read/write direction. All transactions operate on a burst of 2 data (one clock period of bus activity). Synchronous Read/Write Input: When LD# is LOW, this input designates the access type (READ when R, W# is HIGH, WRITE when R, W# is LOW) for the loaded address. R, W# must meet the setup and hold times around the rising edge of K. Synchronous Byte Writes (Nibble Writes on x8): When LOW these inputs cause their respective byte or nibble to be registered and written during WRITE cycles. These signals must meet setup and hold times around the rising edges of K and K# for each of the two rising edges comprising the WRITE cycle. See Pin Configurations for signal to data relationships. x8 device uses NW0#, NW1#. x9 device uses BW0#. x18 device uses BW0#, BW1#. x36 device uses BW0# to BW3#. See Byte Write Operation for relation between BWx#, NWx# and Dxx. Input Clock: This input clock pair registers address and control inputs on the rising edge of K, and registers data on the rising edge of K and the rising edge of K#. K# is ideally 180 degrees out of phase with K. All synchronous inputs must meet setup and hold times around the clock rising edges. Output Clock: This clock pair provides a user controlled means of tuning device output data. The rising edge of C# is used as the output timing reference for first output data. The rising edge of C is used as the output reference for second output data. Ideally, C# is 180 degrees out of phase with C. When use of K and K# as the reference instead of C and C#, then fixed C and C# to HIGH. Operation cannot be guaranteed unless C and C# are fixed to HIGH (i.e. toggle of C and C#). Data Sheet M19866EJ1V0DS PD44164082A-A, 44164092A-A, 44164182A-A, 44164362A-A (2/2) Symbol CQ, CQ# Description TDO Synchronous Echo Clock Outputs. The rising edges of these outputs are tightly matched to the synchronous data outputs and can be used as a data valid indication. These signals run freely and do not stop when DQ tristates. If C and C# are stopped (if K and K# are stopped in the single clock mode), CQ and CQ# will also stop. Output Impedance Matching Input: This input is used to tune the device outputs to the system data bus impedance. DQ, CQ and CQ# output impedance are set to 0.2 x RQ, where RQ is a resistor from this bump to ground. The output impedance can be minimized by directly connect ZQ to VDDQ. This pin cannot be connected directly to GND or left unconnected. The output impedance is adjusted every 1,024 cycles upon power-up to account for drifts in supply voltage and temperature. After replacement for a resistor, the new output impedance is reset by implementing power-on sequence. DLL/PLL Disable: When debugging the system or board, the operation can be performed at a clock frequency slower than TKHKH (MAX.) without the DLL/PLL circuit being used, if DLL# = LOW. The AC/DC characteristics cannot be guaranteed. For normal operation, DLL# must be HIGH and it can be connected to VDDQ through a 10 k or less resistor. IEEE 1149.1 Test Inputs: 1.8 V I/O level. These balls may be left Not Connected if the JTAG function is not used in the circuit. IEEE 1149.1 Clock Input: 1.8 V I/O level. This pin must be tied to VSS if the JTAG function is not used in the circuit. IEEE 1149.1 Test Output: 1.8 V I/O level. VREF HSTL Input Reference Voltage: Nominally VDDQ/2. Provides a reference voltage for the input buffers. VDD VSS Power Supply: 1.8 V nominal. See Recommended DC Operating Conditions and DC Characteristics for range. Power Supply: Isolated Output Buffer Supply. Nominally 1.5 V. 1.8 V is also permissible. See Recommended DC Operating Conditions and DC Characteristics for range.

Data outputs are delivered at C and C# rising edges except if C and C# are HIGH then Data outputs are delivered at K and K# rising edges. 3. All control inputs in the truth table must meet setup/hold times around the rising edge (LOW to HIGH) of K. All control inputs are registered during the rising edge of K. 4. This device contains circuitry that ensure the outputs to be in high impedance during power-up. 5. Refer to state diagram and timing diagrams for clarification. 6. A1 refers to the address input during a WRITE or READ cycle. A2 refers to the next internal burst address in accordance with the linear burst sequence. 7. It is recommended that K = K# = C = C# when clock is stopped. This is not essential but permits most rapid restart by overcoming transmission line charging symmetrically.

When debugging the system or board, these products can operate at a clock frequency slower than TKHKH (MAX.) without the DLL/PLL circuit being used, if DLL# = LOW. Read latency (RL) is changed to 1.5 clock in this operation. The AC/DC characteristics cannot be guaranteed, however. 2. Clock phase jitter is the variance from clock rising edge to the next expected clock rising edge. TKC var (MAX.) indicates a peak-to-peak value. 3. VDD slew rate must be less than 0.1 V DC per 50 ns for DLL/PLL lock retention. DLL/PLL lock time begins once VDD and input clock are stable. It is recommended that the device is kept NOP (LD# = HIGH) during these cycles. 4. K input is monitored for this operation. See below for the timing. K TKC reset or K TKC reset 5. Echo clock is very tightly controlled to data valid / data hold. By design, there is a 0.1 ns variation from echo clock to data. The data sheet parameters reflect tester guardbands and test setup variations. 6. This is a synchronous device. All addresses, data and control lines must meet the specified setup and hold times for all latching clock edges. Remarks 1. This parameter is sampled. 2. Test conditions as specified with the output loading as shown in AC Test Conditions unless otherwise noted. 3. Control input signals may not be operated with pulse widths less than TKHKL (MIN.). 4. If C, C# are tied HIGH, K, K# become the references for C, C# timing parameters. 5. VDDQ is 1.5 V DC.

Test Access Port (TAP) Pins Pin name TCK Pin assignments Description Test Clock Input. 2R All input are captured on the rising edge of TCK and all outputs propagate from the falling edge of TCK. TMS 10R Test Mode Select. This is the command input for the TAP controller state machine. TDI 11R Test Data Input. This is the input side of the serial registers placed between TDI and TDO. The register placed between TDI and TDO is determined by the state of the TAP controller state machine and the instruction that is currently loaded in the TAP instruction. TDO 1R Test Data Output. This is the output side of the serial registers placed between TDI and TDO. Output changes in response to the falling edge of TCK. Remark The device does not have TRST (TAP reset). The Test-Logic Reset state is entered while TMS is held HIGH for five rising edges of TCK. The TAP controller state is also reset on the SRAM POWER-UP.

The register can be loaded when it is placed between the TDI and TDO pins. The instruction register is automatically preloaded with the IDCODE instruction at power-up whenever the controller is placed in test-logic-reset state. Bypass register The bypass register is a single bit register that can be placed between TDI and TDO. It allows serial test data to be passed through the RAMs TAP to another device in the scan chain with as little delay as possible. ID register The ID Register is a 32 bit register that is loaded with a device and vendor specific 32 bit code when the controller is put in capture-DR state with the IDCODE command loaded in the instruction register. The register is then placed between the TDI and TDO pins when the controller is moved into shift-DR state. Boundary register The boundary register, under the control of the TAP controller, is loaded with the contents of the RAMs I/O ring when the controller is in capture-DR state and then is placed between the TDI and TDO pins when the controller is moved to shift-DR state. Several TAP instructions can be used to activate the boundary register. The Scan Exit Order tables describe which device bump connects to each boundary register location. The first column defines the bit's position in the boundary register. The second column is the name of the input or I/O at the bump and the third column is the bump number.

Boundaryscan register cells at output pins are used to apply test vectors, while those at input pins capture test results. Typically, the first test vector to be applied using the EXTEST instruction will be shifted into the boundary scan register using the PRELOAD instruction. Thus, during the update-IR state of EXTEST, the output drive is turned on and the PRELOAD data is driven onto the output pins. IDCODE The IDCODE instruction causes the ID ROM to be loaded into the ID register when the controller is in capture-DR mode and places the ID register between the TDI and TDO pins in shift-DR mode. The IDCODE instruction is the default instruction loaded in at power up and any time the controller is placed in the test-logic-reset state. BYPASS When the BYPASS instruction is loaded in the instruction register, the bypass register is placed between TDI and TDO. This occurs when the TAP controller is moved to the shift-DR state. This allows the board level scan path to be shortened to facilitate testing of other devices in the scan path. SAMPLE / PRELOAD SAMPLE / PRELOAD is a Standard 1149.1 mandatory public instruction. When the SAMPLE / PRELOAD instruction is loaded in the instruction register, moving the TAP controller into the captureDR state loads the data in the RAMs input and DQ pins into the boundary scan register. Because the RAM clock(s) are independent from the TAP clock (TCK) it is possible for the TAP to attempt to capture the I/O ring contents while the input buffers are in transition (i.e., in a metastable state). Although allowing the TAP to sample metastable input will not harm the device, repeatable results cannot be expected. RAM input signals must be stabilized for long enough to meet the TAPs input data capture setup plus hold time (tCS plus tCH). The RAMs clock inputs need not be paused for any other TAP operation except capturing the I/O ring contents into the boundary scan register. Moving the controller to shift-DR state then places the boundary scan register between the TDI and TDO pins. SAMPLE-Z If the SAMPLE-Z instruction is loaded in the instruction register, all RAM DQ pins are forced to an inactive drive state (high impedance) and the boundary register is connected between TDI and TDO when the TAP controller is moved to the shift-DR state.

To disable the TAP Controller without interfering with normal operation of the device, TCK must be tied to VSS to preclude mid level inputs. TDI and TMS may be left open but fix them to VDD via a resistor of about 1 k when the TAP controller is not used. TDO should be left unconnected also when the TAP controller is not used. 32 Data Sheet M19866EJ1V0DS New Instruction PD44164082A-A, 44164092A-A, 44164182A-A, 44164362A-A Run-Test/Idle Update-IR Exit1-IR Shift-IR Exit2-IR IDCODE Pause-IR Exit1-IR Shift-IR Select-IR-Scan Run-Test/Idle Data Sheet M19866EJ1V0DS Instruction Register state TDI Controller state TMS Test-Logic-Reset TDO Output Inactive Select-DR-Scan TCK Test Logic Operation (Instruction Scan) Capture-IR 33 IDCODE PD44164082A-A, 44164092A-A, 44164182A-A, 44164362A-A Test-Logic-Reset Select-IR-Scan Select-DR-Scan Run-Test/Idle Update-DR Exit1-DR Shift-DR Instruction Exit2-DR Pause-DR Exit1-DR Shift-DR Capture-DR 34 Data Sheet M19866EJ1V0DS Instruction Register state TDI Controller state TMS TCK Test Logic (Data Scan) Run-Test/Idle TDO Output Inactive Select-DR-Scan PD44164082A-A, 44164092A-A, 44164182A-A, 44164362A-A Package Drawing 165-PIN PLASTIC BGA (13x15) E w S B ZD ZE B 11 10 9 8 7 6 5 4 3 2 1 A D RPNML K J HGFEDCBA w S A INDEX MARK A y1 A2 S S y e S A1 (UNIT:mm) b x M S AB ITEM D DIMENSIONS 13.000.10 E 15.000.10 w 0.15 e 1.00 A 1.400.11 A1 0.400.05 A2 1.00 b 0.500.05 x 0.08 y 0.10 y1 0.20 ZD 1.50 ZE Data Sheet M19866EJ1V0DS 0.50 P165F5-100-EQ2 35 PD44164082A-A, 44164092A-A, 44164182A-A, 44164362A-A Recommended Soldering Condition Please consult with our sales offices for soldering conditions of these products.

If the input of the CMOS device stays in the area between VIL (MAX) and VIH (MIN) due to noise, etc., the device may malfunction. Take care to prevent chattering noise from entering the device when the input level is fixed, and also in the transition period when the input level passes through the area between VIL (MAX) and VIH (MIN). 2 HANDLING OF UNUSED INPUT PINS Unconnected CMOS device inputs can be cause of malfunction. If an input pin is unconnected, it is possible that an internal input level may be generated due to noise, etc., causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed high or low by using pull-up or pull-down circuitry. Each unused pin should be connected to VDD or GND via a resistor if there is a possibility that it will be an output pin. All handling related to unused pins must be judged separately for each device and according to related specifications governing the device. 3 PRECAUTION AGAINST ESD A strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and ultimately degrade the device operation. Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it when it has occurred. Environmental control must be adequate. When it is dry, a humidifier should be used. It is recommended to avoid using insulators that easily build up static electricity. Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work benches and floors should be grounded. The operator should be grounded using a wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for PW boards with mounted semiconductor devices. 4 STATUS BEFORE INITIALIZATION Power-on does not necessarily define the initial status of a MOS device. Immediately after the power source is turned ON, devices with reset functions have not yet been initialized. Hence, power-on does not guarantee output pin levels, I/O settings or contents of registers. A device is not initialized until the reset signal is received. A reset operation must be executed immediately after power-on for devices with reset functions. 5 POWER ON/OFF SEQUENCE In the case of a device that uses different power supplies for the internal operation and external interface, as a rule, switch on the external power supply after switching on the internal power supply. When switching the power supply off, as a rule, switch off the external power supply and then the internal power supply. Use of the reverse power on/off sequences may result in the application of an overvoltage to the internal elements of the device, causing malfunction and degradation of internal elements due to the passage of an abnormal current. The correct power on/off sequence must be judged separately for each device and according to related specifications governing the device. 6 INPUT OF SIGNAL DURING POWER OFF STATE Do not input signals or an I/O pull-up power supply while the device is not powered. The current injection that results from input of such a signal or I/O pull-up power supply may cause malfunction and the abnormal current that passes in the device at this time may cause degradation of internal elements. Input of signals during the power off state must be judged separately for each device and according to related specifications governing the device.
