STK14CA8C
1-Mbit (128K × 8) nvSRAM
1-Mbit (128K × 8) nvSRAM Features Functional Description
■ 35 ns access time The Cypress STK14CA8C is a fast static RAM, with a nonvolatile element in each memory cell. The memory is organized as ■ Internally organized as 128K × 8 128KB. The embedded nonvolatile elements incorporate ■ Hands-off automatic STORE on power-down with only a smal QuantumTrap technology, producing the world’s most reliable capacitor nonvolatile memory. The SRAM provides infinite read and write cycles, while independent nonvolatile data resides in the highly ■ STORE to QuantumTrap nonvolatile elements initiated by reliable QuantumTrap cell. Data transfers from the SRAM to the software, device pin, or autostore on power-down nonvolatile elements (the STORE operation) takes place ■ RECALL to SRAM initiated by software or power-up automatically at power-down. On power-up, data is restored to the SRAM (the RECALL operation) from the nonvolatile memory. ■ Infinite read, write, and RECALL cycles Both the STORE and RECALL operations are also available ■ 1 million STORE cycles to QuantumTrap under software control. ■ 20-year data retention ■ Single 5 V + 10% operation ■ Industrial and Military temperatures ■ 32-pin CDIP package
