Functional Description[1]

The CY62136EV30 is a high-performance CMOS static RAM

organized as 128K words by 16 bits. This device features

advanced circuit design to provide ultra-low active current.

This is ideal for providing More Battery Life™ (MoBL®) in

portable applications such as cellular telephones. The device

also has an automatic power-down feature that significantly

reduces power consumption by 80% when addresses are not

toggling. The device can also be put into standby mode

reducing power consumption by more than 99% when

deselected (CE HIGH). The input/output pins (I/O0through

I/O15) are placed in a high-impedance state when: deselected

(CE HIGH), outputs are disabled (OE HIGH), both Byte High

Enable and Byte Low Enable are disabled (BHE, BLE HIGH),

or during a write operation (CE LOW and WE LOW).

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/O0through 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/O8through I/O15) is written into the location

specified on the address pins (A0through A16).

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/O0to I/O7. If Byte High Enable (BHE) is

LOW, then data from memory will appear on I/O8to I/O15. See

the truth table at the back of this data sheet for a complete

description of read and write modes.

Notes:

10.Test conditions for all parameters other than tri-state parameters assume signal transition time of3 ns (1V/ns) or less, timing reference levels of VCC(typ)/2, input

pulse levels of 0 to VCC(typ.), and output loading of the specified IOL/IOH as shown in the “AC Test Loads and Waveforms” section.

11.At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZBE is less than tLZBE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any

given device.

12.tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high impedence state.

13.The internal Write time of the memory is defined by the overlap of WE, CE = VIL, BHE and/or BLE = VIL. All signals must be ACTIVE to initiate a write and any

of these signals can terminate a write by going INACTIVE. The data input set-up and hold timing should be referenced to the edge of the signal that terminates

the write.
