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.","metaTitle":"Infineon CY7C1021DV33-10ZSXIT 1Mbit Async SRAM, 10 ns","metaDescription":"Infineon CY7C1021DV33-10ZSXIT 1Mbit (64K x 16) asynchronous SRAM, 10 ns access time, parallel interface, 3V-3.6V, -40°C to 85°C, 44-TSOP II.
