CY14B104KA 数据手册

PRELIMINARY

CY14B104KA, CY14B104MA

4 Mbit (512K x 8/256K x 16) nvSRAM with

Real-Time-Clock

■ Watchdog timer

Features

■ Clock alarm with programmable interrupts

■ Capacitor or battery backup for RTC

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

■ Internally organized as 512K x 8 (CY14B104KA) or 256K x 16

(CY14B104MA)

■ Commercial and industrial temperatures

■ 44 and 54-pin TSOP II package

■ Pb-free and RoHS compliance

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

capacitor

■ STORE to QuantumTrap^®nonvolatile elements is initiated by

software, device pin, or AutoStore^®on power down

Functional Description

■ RECALL to SRAM initiated by software or power up

■ High reliability

The Cypress CY14B104KA/CY14B104MA combines a 4-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 infinite number of times, while independent nonvolatile

data resides in the nonvolatile elements.

■ Infinite read, write, and recall cycles

■ 200,000 STORE cycles to QuantumTrap

■ 20 year data retention

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

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

watchdog timer for process control.

■ Single 3V +20%, –10% operation

■ Data integrity of Cypress nvSRAM combined with full featured

Real-Time-Clock
