It combines the fast read/write cycles of an SRAM (45 ns access time) with automatic non-volatile storage on power loss, eliminating the battery, supervisor IC, and serial EEPROM that a standard SRAM backup scheme requires. The parallel interface and 2.7V to 3.6V supply range make it a drop-in replacement for battery-backed SRAM sockets in industrial controllers, PLCs, and metering equipment where data retention across power cycles is mandatory.","metaTitle":"CY14B101KA-ZS45XI NVSRAM 1Mbit 45ns Infineon","metaDescription":"CY14B101KA-ZS45XI Infineon NVSRAM 1Mbit (128K x 8) 45 ns access time, parallel interface, 2.7V-3.6V, -40°C to 85°C, 44-TSOP II tray.
