What this 1 Mbit asynchronous SRAM brings to the board
The Infineon CY7C1021DV33-10ZSXIT is a 1 Mbit asynchronous SRAM organized as 64K x 16 bits, with a 10 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, making it suitable for embedded systems that need fast, volatile data storage without a clock — think network processors, industrial controllers, or test equipment that cache lookup tables or packet buffers. The 44-TSOP II footprint is a common SRAM package, so layout reuse across board spins is straightforward.
10 ns access time — timing margin matters
Active production — no end-of-life scramble
The CY7C1021DV33-10ZSXIT is listed as Active, so Infineon is still manufacturing it.
