The memory is organized as 32 K words of Infinite read, write, and RECALL cycles 8 bits each. The embedded nonvolatile elements incorporate the 1 million STORE cycles to QuantumTrap QuantumTrap technology, creating the worlds most reliable Data retention: 20 years at 85 C nonvolatile memory. The SRAM provides infinite read and write 2 1 High speed I C interface cycles, while the QuantumTrap cells provide highly reliable nonvolatile storage of data. Data transfers from SRAM to the Industry standard 100 kHz and 400 kHz speed nonvolatile elements (STORE operation) takes place Fast-mode Plus: 1 MHz speed automatically at power-down (except for CY14MX256J1). On High speed: 3.4 MHz power-up, data is restored to the SRAM from the nonvolatile Zero cycle delay reads and writes memory (RECALL operation). The STORE and RECALL 2 Write protection operations can also be initiated by the user through I C commands.

The I C nvSRAM is a single solution which is usable for all four speed modes of operation. As a result, some I/O parameters are slightly different than those on chips which support only one mode of operation. Refer to AN87209 for more details. 2 2. Serial (I C) nvSRAM is referred to as nvSRAM throughout the datasheet.
