Product details

15 ns async SRAM — what the access time buys you

The CY7C1021BNL-15VXCT is a 1Mbit asynchronous SRAM organized as 64K x 16, with a 15 ns access time.

Infineon lists this part as Obsolete. Sourcing is through surplus or broker channels. A replacement must match the 44-SOJ footprint and 5V supply.

44-SOJ footprint — what to check on the board

The package is a 44-lead SOJ (Small Outline J-lead), 0.400" body width, 10.16 mm. If you're trying to fit a replacement, the J-lead pitch and body width are the dimensions that matter — not the Tape & Reel shipping format.
