U631H256 - SoftStore 32K x 8 nvSRAM

Datasheet Summary

Description

The U631H256 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 Times ‡ 10 ns Output Enable Access Times ‡ Software STORE Initiation ‡ 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 EEPROM ‡ Unlimited Read and Write to SRAM ‡ Single 5 V ± 10 % Operation ‡ Operating temperature ranges: 0 to 70 °C -40 to 85 °C ‡ QS 9000 Quality Standard ‡ ESD protection.
