The Infineon CY7C1021BNV33L-15VXIT is a 1 Mbit asynchronous SRAM organized as 64K words by 16 bits.
For a processor running at 33 MHz or slower, this provides enough margin without wait states. If your system uses a faster bus clock, you will need to budget the address-to-data setup against the processor's own timing.
Yes, the lifecycle status for CY7C1021BNV33L-15VXIT is Obsolete. Infineon no longer produces this part.
For a pin-compatible alternative within the CY7C1021 family, check the base product number CY7C1021 for other speed or voltage variants that may still be active. Verify pinout and timing with the datasheet before substituting.
