Overview

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 2.7V~3.6V power supply
  • Small stand-by current: 0.6µA (3.0V, typical)
  • No clocks, No refresh
  • All inputs and outputs are TTL compatible.
  • Easy memory expansion by CS#
  • Common Data I/O
  • Three-state outputs: OR-tie Capability
  • OE# prevents data contention on the I/O bus
