Overview

The Cypress CY14B101P combines a 1 Mbit nonvolatile static

RAM with full featured real time clock in a monolithic integrated

circuit with serial SPI interface. The memory is organized as

128K 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.

■ Real Time Clock

❐ Full featured Real Time Clock

❐ Watchdog timer

❐ Clock alarm with programmable interrupts

❐ Capacitor or battery backup for RTC

❐ Backup current of 300 nA

■ High Speed Serial Peripheral Interface (SPI)

❐ 40 MHz Clock rate - SRAM Memory access

❐ 25 MHz Clock rate - RTC Memory access

❐ Supports SPI Modes 0 (0,0) and 3 (1,1)
