CY14B256LA

CY14B256LA 256 Kbit (32K x 8) nvSRAM Features ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Functional Description The Cypress CY14B256LA is a fast static RAM, with a nonvolatile element in each memory cell. The memory is organized as 32K bytes of 8 bits each. The embedded nonvolatile elements incorporate QuantumTrap technology, producing the world’s most reliable nonvolatile memory. The SRAM provides infinite read and write cycles, while independent nonvolatile data resides in the highly reliable QuantumTrap cell. Data transfers from the SRAM to the nonvolatile elements (the STORE operation) takes place automatically at power down. On power up, data is restored to the SRAM (the RECALL operation) from the nonvolatile memory. Both the STORE and RECALL operations are also available under software control. 25 ns and 45 ns Access Times Internally Organized as 32K x 8 (CY14B256LA) Hands off Automatic STORE on Power Down with only a Small Capacitor STORE to QuantumTrap Nonvolatile Elements Initiated by Software, Device Pin, or AutoStore on Power Down RECALL to SRAM Initiated by Software or Power Up Infinite Read, Write, and Recall Cycles 1 Million STORE Cycles to QuantumTrap 20 year Data Retention Single 3V +20% to -10% Operation Industrial Temperature 44-Pin TSOP - II, 48-Pin SSOP, and 32-Pin SOIC Packages Pb-free and RoHS Compliance www.DataSheet4U.com Cypress Semiconductor Corporation Document Number: 001-54707 Rev. *B 198 Champion Court San Jose, CA 95134-1709 408-943-2600 Revised Dec...
