No official successor or direct pin-compatible replacement is recorded from the original manufacturer. ## 15 ns access and parallel interface fit The 15 ns access time and 15 ns write cycle (word/page) set the memory bus timing. In a 5 V system with a 66 MHz or slower bus, this part keeps the data valid window wide enough for standard ASIC or FPGA interfaces without wait states. The parallel interface is straightforward — address, data, chip enable, output enable, write enable — no clock or refresh overhead. The 44-SOJ package has a JEDEC-standard footprint. Reflow profile should follow the MSL rating on the reel label; the SOJ body is moisture-sensitive, so a bake before reflow is recommended if the seal has been broken and the floor life exceeded.","metaTitle":"Infineon CY7C1021BN-15VXIT 1Mbit SRAM, 15 ns, 44-SOJ","metaDescription":"Infineon CY7C1021BN-15VXIT asynchronous SRAM, 1Mbit (64K x 16), 15 ns access, 4.5-5.5 V, -40 to 85°C, 44-SOJ.
