CY62146CV18 MoBL2™

256K x 16 Static RAM

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/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 and 70 ns availability

• Low voltage range:

— 1.65V–1.95V

• Pin Compatible with CY62146BV18

• Ultra-low active power

— Typical Active Current: 0.5 mA @ f = 1 MHz

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 A₁₇).

— Typical Active Current: 2 mA @ f = f_max(70 ns speed)

• Low standby power

• Easy memory expansion with CE and OE features

• Automatic power-down when deselected

• CMOS for optimum speed/power

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

The CY62146CV18 is a high-performance CMOS static RAM

organized as 256K words by 16 bits. These devices feature

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

The CY62146CV18 is available in a 48-Ball FBGA package.
