U637H256 - CapStore 32K x 8 nvSRAM

Datasheet Summary

Description

The U637H256 has two separate modes of operation: SRAM mode and nonvolatile mode.

In SRAM mode, the memory operates as an ordinary static RAM.

In nonvolatile operation, data is transferred in parallel from SRAM to EEPROM or from EEPROM to SRAM.

Features

  • ‡ High-performance CMOS nonvolatile static RAM 32768 x 8 bits ‡ 25 ns Access Time ‡ 10 ns Output Enable Access Time ‡ ICC = 15 mA typ. at 200 ns Cycle Time ‡ Unlimited Read and Write Cycles to SRAM ‡ Automatic STORE to EEPROM on Power Down using charge stored in an integrated capacitor ‡ Software initiated STORE ‡ Automatic STORE Timing ‡ 106 STORE cycles to EEPROM ‡ 100 years data retention in EEPROM ‡ Automatic RECALL on Power Up ‡ Software RECALL Initiation ‡ Unlimited RECALL cycles from EEPR.
