Description
The R1LP0408D Series is a family of 4-Mbit static RAMs organized 512-kword × 8-bit, fabricated by Renesas’s
high-performance CMOS and TFT technologies. The R1LP0408D Series has realized higher density, higher
performance and low power consumption. The R1LP0408D Series offers low power standby power dissipation;
therefore, it is suitable for battery backup systems. It is offered in 32-pin SOP and 32-pin TSOP.
Features
• Single 5V supply: 4.5V to 5.5V
• Access time: 55/70ns (max)
• Power dissipation:
── Standby: 4µW (typ)
• Equal access and cycle times
• Common data input and output
── Three state output
• Directly TTL compatible
── All inputs and outputs
• Battery backup operation
