Product details

The CY7C1019B-12VC: The 12 ns access time means valid data appears 12 ns after address latch and chip select assertion.

Cypress lists the CY7C1019B-12VC as obsolete.

Package and footprint: 32-SOJ

The part comes in a 32-SOJ (Small Outline J-lead) package with a 0.400-inch body width and 10.16 mm width. It is surface-mount, but the J-lead form factor is less common today than SOIC or TSSOP — make sure your pick-and-place machine has the correct nozzle and feeder for J-lead parts. The supplier device package is 32-SOJ, and the shipping medium is Tube, not Tape & Reel, which may affect your assembly line's feeder setup.

Frequently asked questions

What is a direct replacement for the CY7C1019B-12VC?

There is no official Cypress replacement listed for this exact order code. Any pin-compatible alternative must be a 128K x 8 asynchronous SRAM in a 32-SOJ package with a 12 ns or faster access time and a 5 V supply. Several vendors (ISSI, Alliance Memory, Renesas) offer current-production parts in the same footprint, but you must verify the pinout — particularly the chip-enable and output-enable pin assignments — against the original Cypress datasheet before committing the BOM.
