Unlike battery-backed SRAM, this NVSRAM stores data without a coin cell — the non-volatile element is built into each memory cell, so the data survives power loss without a backup battery or supercap on the board. ## 44-TSOP II — hand-solderable on site Housed in a 44-TSOP II package (0.400-inch body, 10.16 mm wide), the gull-wing leads are visible and accessible with a standard iron — no hot-air station or reflow oven required for a field swap. Supplied in tray format, the parts are oriented and separated; no tape-and-reel handling needed for low-volume or prototype builds. RoHS non-compliant per the listing, so this variant is intended for legacy BOMs that accept tin-lead solder; lead-free assembly lines should source the -Z suffix version.","metaTitle":"Infineon CY14B101LA-ZS45XI NVSRAM, 1Mbit, 45 ns, 44-TSOP II","metaDescription":"Infineon CY14B101LA-ZS45XI NVSRAM, 1Mbit parallel, 45 ns access, 2.7-3.6V, -40 to 85°C, 44-TSOP II.
