Pin Functions
CLK (input pin): CLK is the master clock input pin. The other input signals are referred at CLK rising
edge.
CS (input pin): When CS is Low, the command input cycle becomes valid. When CS is High, all inputs are
ignored. However, internal operations (bank active, burst operations, etc.) are held.
RAS, CAS, and WE (input pins): These pins define operation commands (read, write, etc.) depending on
the combination of their voltage levels. For details, refer to the command operation section.
DSF (input pin): DSF is a part of inputs of graphic commands of the HM5283206. If DSF is LOW, the
HM5283206 operates as standard synchronous DRAM.
A0 to A8 (input pins): Row address (AX0 to AX8) is determined by A0 to A8 pins at the CLK rising edge
when a bank active command is input. Column address (AY0 to AY7) is determined by levels on A0 to A7
pins at the CLK rising edge when a read or write command is input. A8 determins precharge mode. When
A8 is low, only the bank selected by A9 (BS) is precharged by a precharge command. When A8 is high, both
banks are precharged by a precharge command.
A9 (input pin): A9 is the bank select signal (BS). The memory array of the HM5283206 is divided into the
bank 0 and the bank 1, both contain 512 row × 256 column × 32 bits. If A9 is Low, the bank 0 is selected,
and if A9 is High, the bank 1 is selected.
CKE (input pin): By referring low level on CKE pin, HM5283206 determines to go into clock suspend
modes or power down modes. In self refresh mode, low level on this pin is also referred to turn on refresh
process.
DQM0, DQM1, DQM2 and DQM3 (input pins): DQM0 applies to DQ0 to DQ7. DQM1 applies to DQ8
to DQ15. DQM2 applies to DQ16 to DQ23. DQM3 applies to DQ24 to DQ31. In read mode, referring high
level on DQM pins, HM5283206 floats related DQ pins. In write mode, referring high level on DQM pins,
HM5283206 ignores input data through related DQ pins.
DQ0 to DQ31 (input/output): These are the data line for the HM5283206.
VDD and VDDQ (power supply pins): 3.3 V is applied. (VDD is for the internal circuit and VDDQ is power
supply pin for DQ output buffer.)
VSS and VSSQ (power supply pins): Ground is connected. (VSS is for the internal circuit and VSSQ is for DQ
output buffer.)

Graphic Commands
Special mode register set command (SMRS): If each banks is in idle state or activated, at the CLK rising
edge, by setting
CS, RAS, CAS, WE; LOW,
DSF; HIGH,
an internal register (the special mode register; SMRS) are set.
The data through address pins, at the cycle when this command is input, are stored in the special mode
register.
A0 to A4: reserved. should be LOW when SMRS is issued.
A5: determines whether loading mask data or not when SMRS is issued.
A6: determines whether loading color data or not when SMRS is issued.
A7 to A9: reserved. should be set LOW when SMRS is issued.
In case A5 bit of the mode register = HIGH, the data through DQ pins, at the cycle this command is issued,
are stored in the MASK register (32 bits). If write per bit function is available*, and DQi (i = 0,..,31)bit of the
MASK register = LOW, DQi data path to memory array is masked.
In case A6 bit of the mode register HIGH, the data through DQ pins, at the cycle when this command is
issued, are stored in the COLOR register (32 bits). This specific data is written to 8 columns in one clock
cycle by block write command.
Note: When bank active command is issued and DSF set to LOW, write per bit function is enabled.

Operations of HM5283206 Series
Power on sequence: In order to get rid of data contention of I/O bus when power on, the following power on
sequence recommended to be performed before any operation.
1. Apply power and start clock. Keep a NOP condition.
2. Maintain stable power, stable clock, and NOP condition for 200 µs.
3. Execute precharge command (PALL: A8 = HIGH).
4. Execute 8 or more auto refresh commands (REF) tRP after the precharge command as dummy. An interval
tRC is necessary between two consecutive auto refresh commands.
5. Execute a mode register set command (MRS) tRC after the last auto refresh command input.

Read/Write Operations
Bank active: A read/write operation begins with a bank active command (ACTV or ACTVM). The bank
active command determines a bank (A9) and a row address (AX0 to AX8). For the bank and the row, a
read/write command can be applied. An interval not less than tRCD, after an ACTV/ ACTVM command to a
read/write command, is required.
Read operation: Burst length (BL), CAS latency (CL) and burst type (BT) of the mode register are referred
when read command is executed. Burst length (BL) determines the length of a sequential data by a single
read command, which can be set to 1, 2, 4, 8 or 256 (full-page). Starting address of a burst data is defined by
column address (AY0 to AY7) and bank select address (A9) loaded through A0 to A9 in the cycle when the
read command is issued. CAS latency (CL) determines the delay of data output after read command input.
When burst length is 1, 2, 4 or 8, DQ buffers automatically become High-Z at the next cycle after completion
of burst read. When burst length is full-page (256), data are repeatedly output until a burst stop command, a
read/write command or a precharge command is input.

Burst operation (on read or write): One burst data output/input by one read/write command are included in
a column block determined by A1 to A7 in case BL (Burst Length) = 2, by A2 to A7 in case BL = 4 and by
A3 to A7 in case BL = 8. Burst type (BT) determines the order how data of the column block are
output/input. There are two burst types, sequential (wrap around) or interleave. The order of the burst data
depends also on the start cloumn location of the burst data. See tables below for details.

Write operation: OPCODE (A9, A8) of the mode register is referred when a write command is executed as
well as BL (Burst Length) and BT (Burst Type). CL (CAS Latency) is ignored and CL is fixed to 0 for write
operation, that is, write data input starts on the same cycle when the write command is issued.
Burst write: Before executing a burst write operation, OPCODE (A9, A8) should be set to (0, 0). Burst
length (BL) determines the length of a sequential data by the burst write command, which can be set to 1, 2, 4,
8 or 256 (full-page). Starting address of a burst data is defined by column address (AY0 to AY7) and bank
select address (A9) loaded through A0 to A9 in the cycle when the burst write command is issued.

Write per bit: To use write per bit function,
1. Set mask data in advance, which define DQ paths to be masked, to the MASK register by SMRS
command. An interval not less than tRSC after a SMRS command to an ACTVM command is necessary.
2. Use ACTVM command to activate the bank for which write per bit operation is performed. An interval
not less than tRCD, after an ACTVM command to a write or a block write command, is necessary.
3. Execute a write or a block write command. In this write operation, DQ paths defined by mask register are
masked to preserve the previous data. (See the example below)

Block write: Before executing a block write command, a color data (32 bit) should be set in advance, which
is allowed to be written in 8 columns at one write cycle, to the color register by SMRS command. An
interval not less than tRSC after a SMRS command to an ACTVM command is necessary. If a SMRS
command is executed in active state to set the color register, an interval not less than tSBW is required before
executing a block write command after the SMRS command. If a block write command is applied to the bank
which is activated by ACTVM command, write per bit function is also available. DQ inputs at the cycle,
when a block write command is executed, are reffered to mask the specific columns. See the example below.

Auto Precharge
Read with auto precharge: In this operation, since precharge is automatically performed after completing a
read operation, so no precharge commands are necessary after each read operation. The command next to this
command must be a bank active (ACTV, ACTVM) command. In addition, an interval defined by lAPR is
required prior to the next command.
Note: In executing read with auto precharge command, every command to another bank is ignored until
internal precharge completed.

Burst stop command during burst read: Burst stop command is used to stop data output during a full-page
burst read. This command sets the output buffer to High-Z and stops the full-page burst read. The timing,
from command input to the last data, depends on CAS latency. BST command is legitimate only in case full

DQM Control
The DQM i (i=0, 1, 2, 3) controls the ith byte of DQ data. DQM control operation for read and for write are
different in terms of latency.
Reading: When data are read, output buffer can be controlled by DQMi. By setting DQMi to LOW, the
corresponding DQ output buffers become active. By setting DQMi to HIGH, the corresponding DQ output
buffers are made floated so that the ith byte of data are not driven out. The latency of DQM operation for read
operation is 2.

Writing: Input data can be controlled by DQMi. While DQMi is LOW, data is driven into the HM5283206.
By setting DQMi to HIGH, corresponding ith byte of DQ input data are kept from being written to the

Refresh
Auto Refresh: All the banks must be precharged before executing an auto-refresh command. Auto refresh
command increments the internal counter every time when it is executed. This command also determines the
row to be refreshed. Therefore external address specification is not necessary. Refresh cycle is 1024
cycles/16ms. (1024 cycles are required to refresh all the row addresses.) All output buffers become High-Z
after auto-refresh start. No prechrage commands are necessary after this operation.
Self Refresh: When issuing a self refresh command, by changing the level on CKE pin from HIGH to LOW
simultaneously, a self refresh operation starts and is kept while CKE is LOW. During the self-refresh
operation, all data schedule to be refreshed internally. This operation managed by an internal refresh timer.
After exiting from the self refresh, since the last row refreshed cannot be determined, auto-refresh commands
should immediately be performed for all addresses. Change the level on the CKE pin from LOW to HIGH to
exit from Self refresh mode.
Others
Power Down Mode: Power down mode is a state in which all input buffers except the CKE input buffer are
made inactive and clock signal is masked to cut power dissipation. To enter into power down mode, CKE
should be set to low. Power down mode is kept as long as CKE is low. Change the level on the CKE pin
from LOW to HIGH to exit from Power down mode. In this mode, internal refresh is not performed.
Clock S uspend: The HM5283206 enters into clock suspend mode from active mode by setting CKE to low.
There are several types of clock suspend mode depends on the state when CKE level is changed from HIGH
to LOW.
ACTIVE clock suspend: If CKE-transition (1 to 0) happens during a bank active state, the bank active status
is kept. Any input signals are ignored during this mode.
READ and READ A suspend: If CKE transition (1 to 0) happens during a read operation, the read operation
is kept or DQ output data is driven out until completion. Any input signals are ignored during this mode.
WRITE (BLOCK WRITE) and WRITE A (BLOCK WRITE A) suspend: If CKE-transition (1 to 0) happens
during a write operation, though any input signals include DQ input data ignored, the write operation is kept
until completion. Any input signals are ignored during this mode.
Change the level on the CKE pin from LOW to HIGH to exit from Clock suspend mode.

Read Command to Write or Block Write Command Interval:
1. Operation for a column in the same row: The write or the block write command following the preceding
read command can be performed after an interval of no less than 1 cycle. To set DQ output High-Z when data
are driven in, DQM must be used depending on CAS latency as the timing shown below. Note that the latest
write or block write command has the priority to the preceding read command, that is, any write or block
write command can interrupt the preceding burst read operation to get valid data.

Read Command to Precharge Command: The minimum interval between read command and precharge
command is one cycle. However, since the output buffer then becomes High-Z after the cycles defined by
lHZP, there is a possibility that burst read data output will be interrupted, if the precharge command is input
during burst read. To read all data by burst read, the cycles defined by lEP must be assured as an interval from
the final data output to precharge command execution.

Notes: 1. AC measurement assumes tT = 1 ns. Reference level for timing of input signals is 1.4 V.
Test load (A) is used with CL = 30 pF in general except fpr the measurement of access time (note2)
and tHZ (note3).
2. Access time is measured at 1.4 V. Test load (B) is used with current source.
3. tHZ (max) defines the time at which the outputs achieves ± 200 mV. Test load (A) is used with CL =
5 pF and with current source.
4. When Active Suspend Exit, Power Down Exit or Self Refresh Exit is executed.
CKE should be kept “H” more than 1 cycle from these Exit cycles.
