Description
The R1LV0416C-I is a 4-Mbit static RAM organized 256-kword × 16-bit. R1LV0416C-I Series has
realized higher density, higher performance and low power consumption by employing CMOS process
technology (6-transistor memory cell). The R1LV0416C-I Series offers low power standby power
dissipation; therefore, it is suitable for battery backup systems. It has packaged in 44-pin TSOP II.
Features
Single 2.5 V and 3.0 V supply: 2.2 V to 3.6 V
Fast access time: 55/70 ns (max)
Power dissipation:
Active: 5.0 mW/MHz (typ)(VCC = 2.5 V)
: 6.0 mW/MHz (typ) (VCC = 3.0 V)
Standby: 1.25 µW (typ) (VCC = 2.5 V)
: 1.5 µW (typ) (VCC = 3.0 V)
Completely static memory.
No clock or timing strobe required
Equal access and cycle times
Common data input and output.
Three state output
Battery backup operation.
2 chip selection for battery backup
Temperature range: 40 to +85°C
