Product details

Industrial temperature — where it runs

If your board is still 5 V, this part drops straight in without a level shifter.

Infineon (formerly Cypress) lists the CY7C1021BN-15VXE as Obsolete. No last-time-buy window remains; the only supply is through independent distribution — sealed factory reels or tube lots with consistent date-codes.

44-SOJ footprint — board fit

The 44-SOJ (BSOJ, 0.400" body width, 10.16 mm) surface-mount package is a JEDEC-standard footprint. The supplier device package is 44-SOJ.
