CY14C512I

CY14B512I, CY14E512I

512-Kbit (64 K × 8) Serial (I²C) nvSRAM

with Real Time Clock

512-Kbit (64

K × 8) Serial (I²C) nvSRAM with Real Time Clock

■ I²C access to special functions

❐ Nonvolatile STORE/RECALL

❐ 8-byte serial number

❐ Manufacturer ID and Product ID

❐ Sleep mode

Features

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

❐ Internally organized as 64 K × 8

❐ STORE to QuantumTrap nonvolatile elements initiated

automatically on power-down (AutoStore) or by using I²C

command (Software STORE) orHSB pin (Hardware STORE)

■ Low power consumption

❐ Average active current of 1 mA at 3.4 MHz operation

❐ Average standby mode current of 250 µA

❐ Sleep mode current of 8 µA

❐ RECALL to SRAM initiated on power-up (Power-Up

RECALL) or by I²C command (Software RECALL)

❐ Automatic STORE on power-down with a small capacitor

■ Industry standard configurations

❐ Operating voltages:

• CY14C512I : V_CC= 2.4 V to 2.6 V

• CY14B512I : V_CC= 2.7 V to 3.6 V

• CY14E512I : V_CC= 4.5 V to 5.5 V

❐ Industrial temperature

■ High reliability

❐ Infinite read, write, and RECALL cycles

❐ 1 million STORE cycles to QuantumTrap

❐ Data retention: 20 years at 85 C

■ Real Time Clock (RTC)

❐ Full-featured RTC

❐ Watchdog timer

❐ Clock alarm with programmable interrupts

❐ Backup power fail indication

❐ 16-pin small outline integrated circuit (SOIC) package

❐ Restriction of hazardous substances (RoHS) compliant

Overview

❐ Square wave output with programmable frequency (1 Hz,

512 Hz, 4096 Hz, 32.768 kHz)

The Cypress CY14C512I/CY14B512I/CY14E512I combines a

512-Kbit nvSRAM^[1]with a full-featured RTC in a monolithic

integrated circuit with serial I²C interface. The memory is

organized as 64 K words of 8 bits each. The embedded

nonvolatile elements incorporate the QuantumTrap technology,

creating the world’s most reliable nonvolatile memory. The

SRAM provides infinite read and write cycles, while the

QuantumTrap cells provide highly reliable nonvolatile storage of

data. Data transfers from SRAM to the nonvolatile elements

(STORE operation) takes place automatically at power-down.

On power-up, data is restored to the SRAM from the nonvolatile

memory (RECALL operation). The STORE and RECALL

operations can also be initiated by the user through I²C

commands.

❐ Capacitor or battery backup for RTC

❐ Backup current of 0.45 µA (typical)

■ High-speed I²C interface

❐ Industry standard 100 kHz and 400 kHz speed

❐ Fast mode Plus 1 MHz speed

❐ High speed 3.4 MHz

❐ Zero cycle delay reads and writes

■ Write protection

❐ Hardware protection using Write Protect (WP) pin

❐ Software block protection for one-quarter, one-half, or entire

array
