No direct pin-compatible replacement is listed in the available records. ## 1 Mbit organized 64K x 16 Organized as 64K words by 16 bits, this part fits 16-bit data bus applications directly — no byte-lane muxing needed. The 1 Mbit density suits moderate-depth buffers, cache tag stores, and lookup tables in embedded controllers and telecom line cards. The 15 ns write cycle time matches the read access, enabling back-to-back transactions at full bus speed.","metaTitle":"Infineon CY7C1021BNL-15ZXCT SRAM, 1 Mbit, 15 ns, 44-TSOP II","metaDescription":"Infineon CY7C1021BNL-15ZXCT asynchronous SRAM, 1 Mbit (64K x 16), 15 ns access time, 5 V supply, 44-TSOP II.
