CY14MB064Q2A-SXQ

CY14MB064Q2A-SXQ is a CY14MB064Q2A 64Kbit (8K × 8) SPI nvSRAM with extended temperature. 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). User can also initiate the STORE and RECALL operations through SPI instruction.

• 64-Kbit nonvolatile static random access memory (nvSRAM) internally organized as 8K × 8
• 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
• High reliability, infinite read, write, and RECALL cycles
• STORE cycles to QuantumTrap, 1000K cycles at 85°C, 200K cycles at 105°C
• High speed serial peripheral interface, 40MHz clock rate SPI write and read with zero cycle delay
• Supports SPI mode 0 (0, 0) and mode 3 (1, 1), SPI access to special functions
• Software protection using write disable instruction
• VCC = 2.7V to 3.6V operating voltage, 8-pin SOIC (with VCAP) package
• Extended temperature range from –40°C to +105°C
