With a 45 ns access time and 45 ns write cycle, this part matches the timing of standard parallel SRAM, so it drops into a memory slot that expects a 45 ns bus cycle without adding wait states. Housed in a 48-BSSOP body (0.295-inch width, 7.50 mm) with a 48-SSOP supplier package code — surface-mount, 0.80 mm pitch typical for this footprint family. Supplied in tube packaging; the 48-SSOP outline is a standard JEDEC MO-118 variant, so existing land patterns for 48-pin SSOP-7.5 mm accept this part without a board spin.","metaTitle":"Infineon CY14B256KA-SP45XI NVSRAM, 256Kbit, 45 ns, 48-SSOP","metaDescription":"CY14B256KA-SP45XI NVSRAM from Infineon, 256Kbit parallel memory, 45 ns access, 2.7V–3.6V, -40°C to 85°C, 48-SSOP.
