CY62137V MoBL^®

2-Mbit (128K x 16) Static RAM

portable applications such as cellular telephones. The device

also has an automatic power-down feature that reduces power

consumption by 99% when addresses are not toggling. The

device can also be put into standby mode when deselected

(CE HIGH) or when CE is LOW and both BLE and BHE are

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), BHE and BLE are disabled (BHE,

BLE HIGH), or during a write operation (CE LOW, and WE

LOW).

Features

• High Speed

— 55 ns

• Temperature Ranges

— Industrial: –40°C to 85°C

— Automotive: –40°C to 125°C

• Wide voltage range: 2.7V – 3.6V

• 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

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).

• Available in Pb-free and non Pb-free standard

44-pin TSOP Type II package

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.

Functional Description^[1]
