Housed in a 44-TSOP II package (0.400-inch body width, 10.16 mm), the surface-mount footprint suits standard reflow assembly.","metaTitle":"Infineon CY7C1051DV33-12ZSXI 8Mbit Async SRAM, 12 ns","metaDescription":"Obsolete Infineon CY7C1051DV33-12ZSXI asynchronous SRAM, 8Mbit (512K x 16), 12 ns access, 3-3.6 V, -40 to 85°C, 44-TSOP II.
