CY14B116K/CY14B116M

16-Mbit (2048 K × 8/1024 K × 16) nvSRAM with

Real Time Clock

Features

Functional Description

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

❐ 25-ns and 45-ns access times

❐ Internally organized as 2048 K × 8 (CY14B116K),

1024 K × 16 (CY14B116M)

❐ 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

❐ RECALL to SRAM initiated by software or power-up

The Cypress CY14B116K/CY14B116M combines a 16-Mbit

nvSRAM with a full-featured RTC in a monolithic integrated

circuit. The nvSRAM is a fast SRAM with a nonvolatile element

in each memory cell. The memory is organized as 2048 K bytes

of 8 bits each or 1024 K words of 16 bits each. The embedded

nonvolatile elements incorporate the QuantumTrap technology,

producing the world’s most reliable nonvolatile memory. The

SRAM can be read and written an infinite number of times. The

nonvolatile data residing in the nonvolatile elements do not

change when data is written to the SRAM. Data transfers from

the SRAM to the nonvolatile elements (the STORE operation)

takes place automatically at power-down. On power-up, data is

restored to the SRAM (the RECALL operation) from the

nonvolatile memory. Both the STORE and RECALL operations

are also available under software control.

■ High reliability

❐ Infinite read, write, and RECALL cycles

❐ 1 million STORE cycles to QuantumTrap

❐ Data retention: 20 years

■ Sleep mode operation

■ Full-featured real time clock (RTC)

❐ Watchdog timer

❐ Clock alarm with programmable interrupts

❐ Backup power fail indication

❐ Square wave output with programmable frequency

(1 Hz, 512 Hz, 4096 Hz, 32.768 kHz)

❐ Capacitor or battery backup for RTC

❐ Backup current of 0.45 A (typical)

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.

■ Low power consumption

❐ Active current of 75 mA at 45 ns

❐ Standby mode current of 750 A

❐ Sleep mode current of 10 A

■ Operating voltage: V_CC= 2.7 V to 3.6 V

■ Industrial temperature: –40 C to +85 C

■ Packages

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

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

❐ 165-ball fine-pitch ball grid array (FBGA) package

■ Restriction of hazardous substances (RoHS) compliant
