Functional Overview

The Cypress CY14X101Q combines a 1-Mbit nvSRAM with a nonvolatile element in each memory cell with serial SPI interface. The memory is organized as 128 K words of 8 bits each. The embedded nonvolatile elements incorporate the QuantumTrap technology, creating the world’s most reliable nonvolatile memory.

Features

■ 1-Mbit nonvolatile static random access memory (nvSRAM) internally organized as 128 K × 8

  ❐ STORE to QuantumTrap nonvolatile elements initiated automatically on power-down (AutoStore) or by using SPI instruction (Software STORE) or HSB pin (Hardware STORE)

  ❐ RECALL to SRAM initiated on power-up (Power-Up RECALL) or by SPI instruction (Software RECALL)

  ❐ Support automatic STORE on power-down with a small capacitor (except for CY14X101Q1A)

■ High reliability

  ❐ Infinite read, write, and RECALL cycles

  ❐ 1million STORE cycles to QuantumTrap

  ❐ Data retention: 20 years at 85 °C

■ 40 MHz, and 104 MHz High-speed serial peripheral interface(SPI)

  ❐ 40-MHz clock rate SPI write and read with zero cycle delay

  ❐ 104-MHz clock rate SPI write and SPI read (with special fast read instructions)

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

■ SPI access to special functions

  ❐ Nonvolatile STORE/RECALL

  ❐ 8-byte serial number

  ❐ Manufacturer ID and Product ID

  ❐ Sleep mode

■ Write protection

  ❐ Hardware protection using Write Protect (WP) pin

  ❐ Software protection using Write Disable instruction

  ❐ Software block protection for 1/4, 1/2, or entire array

■ Low power consumption

  ❐ Average active current of 3 mA at 40 MHz operation

  ❐ Average standby mode current of 150 A

  ❐ Sleep mode current of 8 A
