32Kx8 PowerStore nvSRAM

FEATURES

DESCRIPTION

• 25, 45 ns Read Access & R/W Cycle Time

The Simtek STK15C88 is a 256Kb fast static RAM

with a non-volatile Quantum Trap storage element

included with each memory cell.

• Unlimited Read/Write Endurance

• Pin compatible with industry standard SRAMs

• Automatic Non-volatile STORE on Power Loss

• Automatic RECALL to SRAM on Power Up

The SRAM provides the fast access & cycle times,

ease of use and unlimited read & write endurance of

a normal SRAM.

• Non-Volatile STORE or RECALL under

Software Control

Data transfers automatically to the non-volatile stor-

age cells when power loss is detected (the STORE

operation). On power up, data is automatically

restored to the SRAM (the RECALL operation). Both

STORE and RECALL operations are also available

under software control.

• Unlimited RECALL Cycles

• 1 Million Store Cycles

• 100-Year Non-volatile Data Retention

• Single 5V +10% Power Supply

• Commercial and Industrial Temperatures

PowerStore nvSRAM products depend on the intrin-

sic system capacitance to maintain system power

long enough for an automatic store on power loss. If

the power ramp from 5 volts to 3.6 volts is faster

than 10 ms, consider our 14C88 or 16C88 for more

reliable operation.

• 28-pin 300-mil and 330 mil SOIC Packages

(RoHS-Compliant)

The Simtek nvSRAM is the first monolithic non-vola-

tile memory to offer unlimited writes and reads. It is

the highest performance, most reliable non-volatile

memory available.
