CY14B101K

1 Mbit (128K x 8) nvSRAM With Real Time Clock

Features

Functional Description

■ Data integrity of Cypress nvSRAM combined with full featured

Real Time Clock (RTC)

The Cypress CY14B101K combines a 1 Mbit nonvolatile static

RAM with a full featured real time clock in a monolithic integrated

circuit. The embedded nonvolatile elements incorporate

QuantumTrap™ technology producing the world’s most reliable

nonvolatile memory. The SRAM is read and written an infinite

number of times, while independent, nonvolatile data resides in

the nonvolatile elements.

■ Watchdog timer

■ Clock alarm with programmable interrupts

■ Capacitor or battery backup for RTC

■ 25 ns, 35 ns, and 45 ns access times

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 alarm or

periodic seconds, minutes, hours, or days. There is also a

programmable watchdog timer for process control.

■ Hands off automatic STORE on power down with only a small

capacitor

■ STORE to QuantumTrap™ initiated by software, device pin, or

on power down

■ RECALL to SRAM initiated by software or on power up

■ Infinite READ, WRITE, and RECALL cycles

■ High reliability

❐ Endurance to 200,000 cycles

❐ Data retention: 20 years at 55°C

■ 10 mA typical I_CCat 200 ns cycle time

■ Single 3V operation +20%, –10%

■ Commercial and industrial temperature

■ SSOP package (ROHS compliant)
