CY62136ESL MoBL^®

2 Mbit (128K x 16) Static RAM

mode reduces power consumption by more than 99% when

deselected (CE HIGH). The input and output pins (IO₀through

IO₁₅) are placed in a high impedance state when:

Features

■ Very high speed: 45 ns

■ Deselected (CE HIGH)

■ Wide voltage range: 2.2V to 3.6V and 4.5V to 5.5V

■ Outputs are disabled (OE HIGH)

■ Ultra low standby power

❐ Typical standby current: 1 μA

❐ Maximum standby current: 7 μA

■ Both Byte High Enable and Byte Low Enable are disabled

(BHE, BLE HIGH)

■ Ultra low active power

❐ Typical active current: 2 mA at f = 1 MHz

■ Write operation is active (CE LOW and WE LOW)

To write to the device, take Chip Enable (CE) and Write Enable

(WE) inputs LOW. If Byte Low Enable (BLE) is LOW, then data

from IO pins (IO₀through IO₇) is written into the location

specified on the address pins (A₀through A₁₆). If Byte High

Enable (BHE) is LOW, then data from IO pins (IO₈through IO₁₅

is written into the location specified on the address pins (A₀

through A₁₆).

■ Easy memory expansion with CE and OE features

■ Automatic power down when deselected

■ CMOS for optimum speed and power

)

■ Available in Pb-free 44-pin TSOP II package

To read from the device, take 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 appears on IO₀to IO₇. If

Byte High Enable (BHE) is LOW, then data from memory

appears on IO₈to IO₁₅. See the “Truth Table” on page 10 for a

complete description of read and write modes.

Functional Description

The CY62136ESL 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 reduces power consumption

when addresses are not toggling. Placing the device into standby

For best practice recommendations, refer to the Cypress

application note AN1064, SRAM System Guidelines.
