Product details

10 ns async SRAM for legacy 5V buses

This part is typically used in legacy networking gear, industrial controllers, and test equipment that still run on a 5V memory bus and need fast, no-wait-state random access.

In a 5V system with a 50 MHz bus (20 ns cycle), this leaves 10 ns of setup margin before the controller latches data — tight but workable with controlled PCB trace lengths.

Package and footprint: 32-SOIC wide body

The part comes in a 32-SOIC package with 0.400-inch body width (10.16 mm), surface-mount.

Frequently asked questions

Where can I buy CY7C1019D-10ZSXIT available via RFQ confirmation?

Submit an RFQ to confirm current availability and pricing; we quote to order against your BOM line.

What is the recommended replacement for CY7C1019D-10ZSXIT?

Infineon does not list a direct drop-in replacement for this specific order code. The CY7C1019D-10ZSXI is the same die in a different shipping medium (tube vs. tape & reel). For a current-production alternative, consider the CY7C1019DV33 series (3.3V) or the CY7C1021DV33 (1Mbit, 5V tolerant) — verify pin compatibility and timing against your design.

Can CY7C1019D-10ZSXIT replace CY7C1019D-10ZSXI?

Yes, electrically and functionally they are the same device. The -10ZSXIT suffix indicates Tape & Reel packaging; the -10ZSXI suffix is tube. Both share the same 10 ns access time, 1Mbit density, and 5V supply range. The only difference is the shipping medium.
