The Infineon CY7C1021BN-12VXIT is a 1Mbit asynchronous SRAM organized as 64K words by 16 bits.
The 12 ns access time means the SRAM presents valid data on its outputs within 12 ns of the address being stable.
This part is officially listed as Obsolete. There is no direct Infineon successor order code. Sourcing runs through independent and surplus distribution.
No official pin-compatible successor or second-source alternate is listed in the available records. For a drop-in replacement, review the 44-SOJ footprint and 5 V asynchronous SRAM family from Alliance Memory or ISSI — but verify timing and supply tolerance against your specific bus timing budget.
It is supplied in a 44-lead SOJ (Small Outline J-Lead) package, 0.400-inch body width, surface-mount, on Tape & Reel.
It is organized as 64K words by 16 bits (1Mbit total), with a 16-bit wide parallel data bus.
