The CY7C1021BNL-15ZXI is a 1 Mbit asynchronous SRAM organized as 64K x 16 bits, from Infineon (formerly Cypress).
Access time is 15 ns per the datasheet.
The CY7C1021BNL-15ZXI is officially marked as Obsolete by Infineon. No further factory orders are accepted. There is no factory-authorized successor listed for this exact order code.
Package is 44-TSOP II (0.400" body width, 10.16 mm wide).
There is no factory-authorized direct replacement listed for this exact order code. For a pin-compatible drop-in, look for other 1 Mbit (64K x 16) asynchronous SRAMs in 44-TSOP II with 15 ns access time and 5 V supply from vendors like ISSI, Alliance Memory, or Renesas. Verify the pinout and timing before committing the BOM.
