It combines a full-speed SRAM core with a non-volatile element, so data written to the array is retained when power is removed — no battery, no supercap, no EEPROM wear-out. The parallel interface and 45 ns access time let it drop into a standard asynchronous SRAM socket while adding non-volatility for configuration parameters, calibration constants, or event logs. ## 45 ns access — timing margin for the bus The 45 ns access time and 45 ns write cycle time match the read-cycle timing of many mid-range MCUs and FPGAs. Cypress lists this part as Active. No NRND or last-time-buy notices are on record. ## Sourcing posture: quoted to order","metaTitle":"Cypress CY14B104NA-ZS45XI NVSRAM, 4 Mbit, 45 ns, Parallel","metaDescription":"Cypress CY14B104NA-ZS45XI 4 Mbit NVSRAM in TSOP II, 45 ns access, parallel interface, 2.7 V supply, -40°C to 85°C.
