Functional Description

The Cypress CY14B256KA combines a 256-Kbit 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.

Features

■ 256-Kbit nonvolatile static random access memory (nvSRAM)

❐ 25 ns and 45 ns access times

❐ Internally organized as 32 K × 8 (CY14B256KA)

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

❐ STORE to QuantumTrap nonvolatile elements is initiated by software, hardware, or AutoStore on power-down

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

■ High reliability

❐ 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)

■ Industry standard configurations

❐ Single 3 V +20, –10 operation

❐ Industrial temperature

❐ 48-pin shrink small-outline package (SSOP)

❐ Pb-free and Restriction of hazardous substances (RoHS) compliant
