× 8/64K × 16) nvSRAM with Real Time Clock

■ Industry standard configurations

❐ Single 3 V +20%, –10% operation

❐ Industrial temperature

Features

■ 1-Mbit nonvolatile static random access memory (nvSRAM)

❐ 25 ns and 45 ns access times

❐ Internally organized as 128K × 8 (CY14B101KA) or 64K × 16

(CY14B101MA)

❐ STORE to QuantumTrap nonvolatile elements is initiated by

software, hardware, or AutoStore on power-down

■ Packages

❐ 44-/54-pin thin small outline package (TSOP) Type II

❐ 48-pin shrink small outline package (SSOP)

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

❐ RECALL to SRAM initiated on power-up or by software

Functional Description

■ High reliability

The Cypress CY14B101KA/CY14B101MA combines a 1-Mbit

nvSRAM 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.

❐ Infinite Read, Write, and RECALL cycles

❐ 1 million STORE cycles to QuantumTrap

❐ 20 year data retention

■ Real time clock (RTC)

❐ Full featured real time clock

❐ Watchdog timer

❐ Clock alarm with programmable interrupts

❐ Capacitor or battery backup for RTC

❐ Backup current of 0.35 µA (Typ)

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 periodic minutes, hours,

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

timer for process control.
