It combines the fast read/write of an SRAM — 45 ns access time — with non-volatile storage that holds data when power drops, eliminating the battery backup that traditional SRAM designs need. ## 45 ns access — no wait states on a 22 MHz bus With a 45 ns access time and matching 45 ns write cycle (word/page), this part keeps pace with a 22 MHz bus without inserting wait states. The parallel interface maps directly into the memory space of a 16-bit MCU or MPU — no SPI or I2C protocol overhead to eat into throughput. ## 44-TSOP II — 0.400-inch body, surface-mount The 0.8 mm pin pitch is board-friendly — two-layer prototypes can route it without micro-vias. Supplied in tray format, which suits low-to-medium volume assembly and prototyping. For high-volume pick-and-place, trays transfer directly to the feeder without re-reeling. ## Active lifecycle, ROHS3 — no compliance surprises It is ROHS3 compliant, so no exemption conflicts for EU or California markets.","metaTitle":"Infineon CY14B101NA-ZS45XI NVSRAM, 1Mbit, 45 ns, 44-TSOP","metaDescription":"Infineon CY14B101NA-ZS45XI NVSRAM, 1Mbit, 45 ns access, parallel interface, 44-TSOP II, -40 to 85°C.
