STK17TA8

128k X 8 AutoStore™ nvSRAM

with Real Time Clock

Features

Description

■ nvSRAMCombinedwithIntegratedRealTimeClockFunctions

(RTC, Watchdog Timer, Clock Alarm, Power Monitor)

The Cypress STK17TA8 combines a 1 Mb nonvolatile static RAM

(nvSRAM) with a full featured real time clock in a reliable,

monolithic integrated circuit.

■ Capacitor or Battery Backup for RTC

■ 25, 45 ns Read Access and Read/Write Cycle Time

■ Unlimited Read/Write Endurance

The 1 Mb nvSRAM is a fast static RAM with a nonvolatile

Quantum Trap storage element included with each memory cell.

The SRAM provides the fast access and cycle times, ease of use

and unlimited read and write endurance of a normal SRAM. Data

transfers automatically to the nonvolatile 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 nonvolatile STORE on Power Loss

■ Nonvolatile STORE Under Hardware or Software Control

■ Automatic RECALL to SRAM on Power Up

■ Unlimited RECALL Cycles

The real time clock function provides an accurate clock with leap

year tracking and a programmable, high accuracy oscillator. The

Alarm function is programmable for one-time alarms or periodic

minutes, hours, or days alarms. There is also a programmable

watchdog timer for processor control.

■ 200K STORE Cycles

■ 20-Year nonvolatile Data Retention

■ Single 3 V +20%, -10% Power Supply

■ Commercial and Industrial Temperatures

■ 48-pin 300-mil SSOP Package (RoHS-Compliant)
