CY62148DV30

4-Mb (512K x 8) MoBL^Static RAM

Features

Functional Description^[1]

• Very high speed: 55 ns

The CY62148DV30 is a high-performance CMOS static RAMs

organized as 512K words by 8 bits. This device features

advanced circuit design to provide ultra-low active current.

— Wide voltage range: 2.20V – 3.60V

• Pin-compatible with CY62148CV25, CY62148CV30 and

CY62148CV33

• Ultra low active power

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. The device can be put into

standby mode reducing power consumption when deselected

(CE HIGH).

— Typical active current: 1.5 mA @ f = 1 MHz

— Typical active current: 8 mA @ f = f_max(55-ns speed)

• Ultra low standby power

• Easy memory expansion with CE, and OE features

• 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. Data on the eight I/O

pins (I/O₀through I/O₇) is then written into the location

specified on the address pins (A₀through A₁₈).

• Packages offered: 36-ball BGA, 32-pin TSOPII and

32-pin SOIC

Reading from the device is accomplished by taking Chip

Enable (CE) and Output Enable (OE) LOW while forcing Write

Enable (WE) HIGH. Under these conditions, the contents of

the memory location specified by the address pins will appear

on the I/O pins.

The eight input/output pins (I/O₀through I/O₇) are placed in a

high-impedance state when the device is deselected (CE

HIGH), the outputs are disabled (OE HIGH), or during a write

operation (CE LOW and WE LOW).
