The 44-TSOP II footprint is common across multiple vendors, so a board designed for this part can often accept an ISSI or Alliance Memory equivalent with no layout change, provided the timing and supply match. Not rated for industrial enclosures, outdoor cabinets, or automotive under-hood.","metaTitle":"Infineon CY7C1041BNV33L-15ZXC 4Mbit Async SRAM, 15 ns","metaDescription":"Infineon CY7C1041BNV33L-15ZXC 4Mbit asynchronous SRAM, 256K x 16, 15 ns access time, 3V–3.6V, 0°C–70°C, 44-TSOP II.
