CY62136V MoBL(R) 2-Mbit (128K x 16) Static RAM Features advanced circuit design to provide ultra-low active current. This is ideal for providing More Battery LifeTM (MoBL(R)) in portable applications such as cellular telephones. The device also has an automatic power-down feature that significantly reduces power consumption by 99% when addresses are not toggling. The device can also be put into standby mode when deselected (CE HIGH). The input/output pins (I/O0 through I/O15) are placed in a high-impedance state when: deselected (CE HIGH), outputs are disabled (OE HIGH), BHE and BLE are disabled (BHE, BLE HIGH), or during a write operation (CE LOW, and WE LOW). * Temperature Ranges -- Commercial: 0C to 70C -- Industrial: -40C to 85C -- Automotive: -40C to 125C * High speed: 55 ns and 70 ns * 70-ns speed bin offered in both Industrial and Automotive grades * Wide voltage range: 2.7V-3.6V Writing to the device is accomplished by taking Chip Enable (CE) and Write Enable (WE) inputs LOW. If Byte Low Enable (BLE) is LOW, then data from I/O pins (I/O0 through I/O7), is written into the location specified on the address pins (A0 through A16). If Byte High Enable (BHE) is LOW, then data from I/O pins (I/O8 through I/O15) is written into the location specified on the address pins (A0 through A16). * Ultra-low active, standby power * Easy memory expansion with CE and OE features * TTL-compatible inputs and outputs * Automatic power-down when deselected * CMOS for optimum speed/power * Package available in a standard 44-pin TSOP Type II (forward pinout) package * Also available in Lead-free package Functional Description[1] The CY62136V is a high-performance CMOS static RAM organized as 128K words by 16 bits. This device features Reading from the device is accomplished by taking Chip Enable (CE) and Output Enable (OE) LOW while forcing the Write Enable (WE) HIGH. If Byte Low Enable (BLE) is LOW, then data from the memory location specified by the address pins will appear on I/O0 to I/O7. If Byte High Enable (BHE) is LOW, then data from memory will appear on I/O8 to I/O15. See the Truth Table at the back of this data sheet for a complete description of read and write modes.

Full device operation requires linear VCC ramp from VDR to VCC(min) > 100 ms or stable at VCC(min) > 100 ms. 8. Test conditions assume signal transition time of 5 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to VCC typ., and output loading of the specified IOL/IOH and 30-pF load capacitance. 9. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any given device. 10. tHZOE, tHZCE, and tHZWE are specified with CL = 5 pF as in (b) of AC Test Loads. Transition is measured 500 mV from steady-state voltage. 11. The internal write time of the memory is defined by the overlap of CE LOW and WE LOW. Both signals must be LOW to initiate a write and either signal can terminate a write by going HIGH. The data input set-up and hold timing should be referenced to the rising edge of the signal that terminates the write. 12. The minimum write cycle time for write cycle 3 (WE controlled, OE LOW) is the sum of tHZWE and tSD.
