CY14B101LA CY14B101NA 1-Mbit (128 K 8/64 K 16) nvSRAM 1-Mbit (128 K 8/64 K 16) nvSRAM Packages Features 32-pin small-outline integrated circuit (SOIC) 20 ns, 25 ns, and 45 ns access times 44-/54-pin thin small outline package (TSOP) Type II 48-pin shrink small-outline package (SSOP) Internally organized as 128 K 8 (CY14B101LA) or 64 K 16 48-ball fine-pitch ball grid array (FBGA) (CY14B101NA) Pb-free and restriction of hazardous substances (RoHS) Hands off automatic STORE on power-down with only a small compliant capacitor STORE to QuantumTrap nonvolatile elements initiated by Functional Description software, device pin, or AutoStore on power-down The Cypress CY14B101LA/CY14B101NA is a fast static RAM RECALL to SRAM initiated by software or power-up (SRAM), with a nonvolatile element in each memory cell. The Infinite read, write, and RECALL cycles memory is organized as 128 K bytes of 8 bits each or 64 K words of 16 bits each. The embedded nonvolatile elements incorporate 1 million STORE cycles to QuantumTrap QuantumTrap technology, producing the worlds most reliable 20 year data retention nonvolatile memory. The SRAM provides infinite read and write cycles, while independent nonvolatile data resides in the highly Single 3 V +20% to 10% operation reliable QuantumTrap cell. Data transfers from the SRAM to the Industrial temperature 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.
