The Infineon CY7C1021CV33-15ZSXA is a 1Mbit asynchronous SRAM organized as 64K x 16 bits, with a 15 ns access time and a parallel interface. It operates from a 3V to 3.6V supply and is rated for the industrial temperature range of -40°C to 85°C. This makes it suitable for cache buffers, data logging, or real-time control memory in factory automation, telecom infrastructure, and outdoor equipment where the board sees extended temperature swings.
The 15 ns access time and 15 ns write cycle time match, enabling back-to-back reads and writes at the same speed without dead cycles.
