Description
The R1LV0414D is a 4-Mbit static RAM organized 256-kword × 16-bit, fabricated by Renesas’s high-performance 0.15µm CMOS and TFT technologies. R1LV0414DSeries has realized higher density, higher performance and low power consumption. The R1LV0414D 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 3.0 V supply: 2.7 V to 3.6 V Fast access time: 55/70 ns (max) Power dissipation: Standby: 3 µW (typ) (VCC = 3.0 V) Equal access and cycle times Common data input and output. Three state output Battery backup operation. Temperature range: -40 to +85°C
Ordering Information
Type No. R1LV0414DSB-5SI R1LV0414DSB-7LI Access time 55 ns 70 ns Package 400-mil 44-pin plastic TSOP II (44P3W-H)
