Product details

10 ns async SRAM for the 16-bit bus — what the ratings mean

The x16 organization maps directly onto a 16-bit data bus without byte-lane steering, saving glue logic.

44-TSOP II — rework and footprint notes

The 44-TSOP II package (0.400" body width, 10.16 mm) is a fine-pitch surface-mount package with gull-wing leads. The 0.400" width is wider than the 0.525" TSOP, so verify the land pattern matches the supplier device package (44-TSOP II, not 44-TSOP).

Supply rail and decoupling

A 0.1 µF ceramic cap at each VDD pin, plus a 4.7 µF bulk cap near the package, is standard.

This means no last-time-buy pressure and no forced redesign for a drop-in replacement.

Frequently asked questions

What is the closest pin-compatible alternative to CY7C1021CV33-10ZSXAT?

The CY7C1021 family includes multiple speed and voltage grades, but a direct drop-in alternate from another manufacturer is not confirmed. For dual-sourcing options, contact us with your volume and target price.
