SRAM Chip Async Single 3V 256K-Bit 32K x 8 70ns 28-Pin SOP Tube

The R1LV5256E Series is a family of low voltage 256-Kbit static RAMs organized as 32,768-word by 8-bit, fabricated by Renesas’s high-performance 0.15um CMOS and TFT technologies. The R1LV5256E Series has realized higher density, higher performance and low power consumption. The R1LV5256E Series is suitable for memory applications where a simple interfacing, battery operating and battery backup are the important design objectives. It has been packaged in 28-pin SOP and 28-pin TSOP.

• Single 2.7~3.6V power supply
• Small stand-by current: 1 µA (3.0V, typical)
• No clocks, No refresh
• All inputs and outputs are TTL compatible.
• Easy memory expansion by CS1#, CS2, LB# and UB#
• Common Data I/O
• Three-state outputs: OR-tie Capability
• OE# prevents data contention on the I/O bus
