Frequently asked questions
What is the closest pin-compatible alternative to CY7C1021CV33-12ZXI?
The evidence does not list an official pin-compatible alternative. Several 1Mbit asynchronous SRAMs in 44-TSOP II from ISSI (IS61LV1024-12TI) and Alliance Memory (AS7C1024B-12TIN) share the same footprint and 12 ns speed grade — verify the full pinout and timing parameters against the CY7C1021 datasheet before substituting.
What is the operating temperature range of this SRAM?
The CY7C1021CV33-12ZXI is rated for the industrial temperature range of -40°C to 85°C.
