STK25C48

2K x 8 AutoStore™ nvSRAM

QuantumTrap™ CMOS

Nonvolatile Static RAM

Obsolete - Not Recommend for new Designs

DESCRIPTION

FEATURES

The STK25C48 is a fast SRAM with a nonvolatile 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 the Nonvolatile

Elements. Data transfers from the SRAM to the Nonvola-

tile Elements (the STORE operation) can take place auto-

matically on power down using charge stored in system

capacitance. Transfers from the Nonvolatile Elements to

the SRAM (the RECALL operation) take place automati-

cally on restoration of power. The nvSRAM can be used in

place of existing 2K x 8 SRAMs and also matches the

pinout of 2K x 8 battery-backed SRAMs, EPROMs and

EEPROMs, allowing direct substitution while enhancing

performance. No support circuitry is required for micro-

processor interfacing.

• Nonvolatile Storage without Battery Problems

• Directly Replaces 2K x 8 Static RAM, Battery-

Backed RAM or EEPROMs

• 25ns, 35ns and 45ns Access Times

• STORE to Nonvolatile Elements Initiated by

AutoStore™ on Power Down

• RECALL to SRAM Initiated by Power Restore

• 10mA Typical I_CCat 200ns Cycle Time

• Unlimited READ, WRITE and RECALL Cycles

• 1,000,000 STORE Cycles to Nonvolatile Ele-

ments

• 100-Year Data Retention over Full Industrial

Temperature Range

• Commercial and Industrial Temperatures

• 24-Pin 600 PDIP Package
