Description
The R1LV0408C-I is a 4-Mbit static RAM organized 512-kword × 8-bit. R1LV0408C-I Series has
realized higher density, higher performance and low power consumption by employing CMOS process
technology (6-transistor memory cell). The R1LV0408C-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 and 32-pin STSOP.
Features
• Single 3 V supply: 2.7 V to 3.6 V
• Access time: 55/70 ns (max)
• Power dissipation:
Active: 6 mW/MHz (typ)
Standby: 1.5 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
