U63716 - CapStore 2K x 8 nvSRAM

Datasheet Summary

Description

The U63716 has two separate modes of operation: SRAM mode and nonvolatile mode.

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

In non-volatile operation, data is transferred in parallel from SRAM to EEPROM or from EEPROM to SRAM.

Features

  • CMOS non- volatile static RAM 2048 x 8 bits 70 ns Access Time 35 ns Output Enable Access Time ICC = 15 mA 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 ST.

Obsolete - Not Recommended for New Designs www.DataSheet4U.com U63716 CapStore 2K x 8 nvSRAM Description The U63716 has two separate modes of operation: SRAM mode and nonvolatile mode. In SRAM mode, the memory operates as an ordinary static RAM. In non-volatile operation, data is transferred in parallel from SRAM to EEPROM or from EEPROM to SRAM. In this mode SRAM functions are disabled. The U63716 is a static RAM with a non-volatile electrically erasable PROM (EEPROM) element incorporated in each static memory cell. The SRAM can be read and written an unlimited number of times, while independent nonvolatile data resides in EEPROM. Data transfers from the SRAM to the EEPROM (the STORE operation) take place automatically upon power down using charge stored in an integrated capacitor.
