CY62167GN MoBL^®

16-Mbit (1M × 16/2M × 8) Static RAM

16-Mbit (1M

× 16/2M × 8) Static RAM

Features

Functional Description

■ Ultra-low standby power

❐ Typical standby current: 5.5 A

❐ Maximum standby current: 16 A

The CY62167GN is a high performance CMOS static RAM

organized as 1M words by 16 bits or 2M words by 8 bits. This

device features an advanced circuit design that provides an ultra

low active current. Ultra low active current 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 by 99 percent

when addresses are not toggling. Place the device into standby

mode when deselected (CE₁HIGH or CE₂LOW or both BHE and

■ TSOP I package configurable as 1M × 16 or 2M × 8 SRAM

■ Very high speed: 45 ns

■ Temperature ranges

❐ Industrial: –40 °C to +85 °C

BLE are HIGH). The input and output pins (I/O₀through I/O₁₅

)

■ Wide voltage range: 1.65 V to 2.2 V, 2.2 V to 3.6 V, and 4.5 V

to 5.5 V

are placed in a high impedance state when: the device is

deselected (CE₁HIGH or CE₂LOW), outputs are disabled (OE

HIGH), both Byte High Enable and Byte Low Enable are disabled

(BHE, BLE HIGH), or a write operation is in progress (CE₁LOW,

CE₂HIGH and WE LOW).

■ Easy memory expansion with CE₁, CE₂, and OE Features

■ Automatic power-down when deselected

■ CMOS for optimum speed and power

To write to the device, take Chip Enables (CE₁LOW and CE₂

HIGH) and Write Enable (WE) input 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 (A₀through

A₁₉). If Byte High Enable (BHE) is LOW, then data from the I/O

pins (I/O₈through I/O₁₅) is written into the location specified on

the address pins (A₀through A₁₉).

■ Offered in Pb-free 48-ball VFBGA and 48-pin TSOP I packages

To read from the device, take Chip Enables (CE₁LOW and CE₂

HIGH) 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 I/O₀to I/O₇. If Byte High Enable (BHE) is LOW, then data from

memory appears on I/O₈to I/O₁₅. See Truth Table on page 13

for a complete description of read and write modes.
