128Kx8 Autostore nvSRAM With Real-Time Clock

DESCRIPTION

FEATURES

The Simtek STK17TA8 combines a 1Mb non-volatile

static RAM (nvSRAM) with a full-featured real-time

clock in a reliable, monolithic integrated circuit.

• nvSRAM Combined With Integrated Real-Time

Clock Functions (RTC, Watchdog Timer, Clock

Alarm, Power Monitor)

The 1Mbit nvSRAM is a fast static RAM with a non-

volatile Quantum Trap storage element included

with each memory cell.

• Capacitor or Battery Backup for RTC

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

• Unlimited Read/Write Endurance

The SRAM provides the fast access & cycle times,

ease of use and unlimited read & write endurance of

a normal SRAM. Data transfers automatically to the

non-volatile storage 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.

• Automatic Non-volatile STORE on Power Loss

• Non-Volatile STORE Under Hardware or Software

Control

• Automatic RECALL to SRAM on Power Up

• Unlimited RECALL Cycles

• 200K STORE Cycles

The real time clock function provides an accurate

clock with leap year tracking and a programmable,

high accuracy oscillator. The Alarm function is pro-

grammable for one-time alarms or periodic minutes,

hours, or days alarms. There is also a programma-

ble watchdog timer for processor control.

• 20-Year Non-volatile Data Retention

• Single 3 V + 20%, -10% Power Supply

• Commercial and Industrial Temperatures

• Small Footprint SSOP Package (RoHS-

Compliant)
