CY14B104K/CY14B104M

4-Mbit (512 K × 8/256 K × 16) nvSRAM

with Real Time Clock

4-Mbit (512

K × 8/256 K × 16) nvSRAM with Real Time Clock

■ Watchdog timer

Features

■ Clock alarm with programmable interrupts

■ Capacitor or battery backup for RTC

■ 25 ns and 45 ns access times

■ Internally organized as 512 K × 8 (CY14B104K) or 256 K × 16

(CY14B104M)

■ Industrial temperature

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

capacitor

■ 44-pin and 54-pin thin small outline package (TSOP) Type II

■ Pb-free and restriction of hazardous substances (RoHS)

compliant

■ STORE to QuantumTrap nonvolatile elements is initiated by

software, device pin, or AutoStore on power-down

Functional Description

■ RECALL to SRAM is initiated by software or power-up

■ High reliability

The Cypress CY14B104K and CY14B104M combines a 4-Mbit

nonvolatile static RAM (nvSRAM) with a full-featured RTC 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 infinite number of times, while independent nonvolatile

data resides in the nonvolatile elements.

■ Infinite read, write, and RECALL cycles

■ 1 million STORE cycles to QuantumTrap

■ 20 year data retention

■ Single 3 V +20%, –10% operation

The RTC function provides an accurate clock with leap year

tracking and a programmable, high accuracy oscillator. The

alarm function is programmable for periodic minutes, hours,

days, or months alarms. There is also a programmable watchdog

timer for process control.

■ Data integrity of Cypress nvSRAM combined with full-featured

real time clock (RTC)
