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.
