Product Highlight

  • Memory Density: 1 Mb
  • Memory Organization: 128 k x 8
  • Supply Voltage-Nom: 3 V
  • Temperature Grade: Industrial

The CY14B101Q2A-SXI is a 1-Mbit nvSRAM with a non-volatile 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. The SRAM provides infinite read and write cycles, while the QuantumTrap cells provide highly reliable nonvolatile storage of data.


  • 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 µA
    • Sleep mode current of 8 µA
