MoBL2

8M (512K x 16) Static RAM

deselected Chip Enable 1 (CE₁) HIGH or Chip Enable 2 (CE₂)

LOW or both BHE and BLE are HIGH. The input/output pins

(I/O₀through I/O₁₅) are placed in a high-impedance state

when: deselected Chip Enable 1 (CE₁) HIGH or Chip Enable

2 (CE₂) LOW, outputs are disabled (OE HIGH), both Byte High

Enable and Byte Low Enable are disabled (BHE, BLE HIGH)

or during a write operation (Chip Enable 1 (CE₁) LOW and

Chip Enable 2 (CE₂) HIGH and WE LOW).

Features

• Very high speed: 55 ns

• Wide voltage range: 1.65V to 2.2V

• Pin compatible with CY62157CV18

• Ultra low active power

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

— Typical active current: 10 mA @ f = fmax

• Ultra low standby power

• 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

Writing to the device is accomplished by taking Chip Enable 1

(CE₁) LOW and Chip Enable 2 (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 A₁₈). 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 A₁₈).

Functional Description^[1]

Reading from the device is accomplished by taking Chip

Enable 1 (CE₁) LOW and Chip Enable 2 (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 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.

The CY62157DV20 is a high-performance CMOS static RAM

organized as 512K 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

reduces power consumption by 99% when addresses are not

toggling. The device can also be put into standby mode when
