Hitachi -> Renesas Electronics 

HM62256A Series

32,768-word × 8-bit High Speed CMOS Static RAM

Maintenance only

The Hitachi HM62256A is a CMOS static RAM

organized 32-kword × 8-bit. It realizes higher

performance and low power consumption by

employing 0.8 µm Hi-CMOS process technology.

The device, packaged in a 8 × 14 mm TSOP with

thickness of 1.2 mm, 450-mil SOP (foot print pitch

width), 600-mil plastic DIP, or 300-mil plastic DIP,

is available for high density mounting. TSOP

package is suitable for cards, and reverse type

TSOP is also provided. It offers low power

standby power dissipation; therefore, it is suitable

for battery back up system.

Features

• High speed: Fast Access time 85/100/120/150 ns

(max)

• Low Power

Standby: 5 µW (typ) (L/L-SL version)

Operation: 40 mW (typ) (f = 1 MHz)

• Single 5 V supply

• Completely static memory

No clock or timing strobe required

• Equal access and cycle times

• Common data input and output: Three state

output

• Directly TTL compatible: All inputs and outputs

• Capability of battery back up operation

Ordering Information

Type No.
