Product details

15 ns access time — bus timing margin for 5 V systems

The Infineon CY7C1021BNL-15ZXC is a 1 Mbit asynchronous SRAM organized 64K x 16, with a 15 ns access time.

64K x 16 organization — why the 16-bit bus matters

The 64K x 16 organization means the part presents a full 16-bit data word on each access, matching the native bus width of 16-bit microcontrollers.

Infineon lists the CY7C1021BNL-15ZXC as Active.
