CY14B512PA - 512-Kbit (64 K x 8) SPI nvSRAM

General Description

9 Status Register 10 Read Status Register (RDSR) Instruction 10 Fast Read Status Register (FAST_RDSR) Instruction 10 Write Status Register (WRSR) Instruction 10 Write Protection and Block Protection 11 Write Enable (WREN) Instruction 11 Write Disable (WRDI) Instruction 12 Block Protection 1

Key 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 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).
  • Automatic STORE on power-down with a small capacitor.
  • High reliability.
  • Infinite read, write, and RECALL cycles.
