Description

The R1LP0408C-I is a 4-Mbit static RAM organized 512-kword

× 8-bit. R1LP0408C-I Series has realized

higher density, higher performance and low power consumption by employing CMOS process technology

(6-transistor memory cell). The R1LP0408C-I Series offers low power standby power dissipation;

therefore, it is suitable for battery backup systems. It has packaged in 32-pin SOP, 32-pin TSOP II.

Features

• Single 5 V supply: 5 V ± 10%

• Access time: 55/70 ns (max)

• Power dissipation:

 Active: 10 mW/MHz (typ)

 Standby: 4 µW (typ)

• 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

• Battery backup operation.

• Operating temperature: −40 to +85°C
