CY62177DV30

MoBL^®

32-Mbit (2M x 16) Static RAM

reduces power consumption. The device can also be put into

standby mode when deselected (CE₁HIGH or CE₂LOW or

both BHE and BLE are HIGH). The input/output pins (I/O₀

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

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

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

disabled (BHE, BLE HIGH), or during a write operation (CE₁

LOW, CE₂HIGH and WE LOW).

Features

• Very high speed: 55 ns and 70 ns

• Wide voltage range: 2.20V–3.60V

• Ultra-low active power

— Typical active current: 2 mA @ f = 1 MHz

— Typical active current: 15 mA @ f = f_max

• Ultra low standby power

Writing to the device is accomplished by taking Chip Enables

(CE₁LOW and CE₂HIGH) and Write Enable (WE) input LOW.

If Byte Low Enable (BLE) is LOW, then data from I/O pins (I/O₀

through I/O₇), is written into the location specified on the

address pins (A₀through A₂₀). 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 A₂₀).

• Easy memory expansion with CE₁, CE₂and OE features

• Automatic power-down when deselected

• CMOS for optimum speed/power

• Packages offered in a 48-ball FBGA

Reading from the device is accomplished by taking Chip

Enables (CE₁LOW and CE₂HIGH) 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 for a complete description

of read and write modes.

Functional Description^[1]

The CY62177DV30 is a high-performance CMOS static RAM

organized as 2M 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
