Product details

The CY7C1021BNV33L-10ZXC: The 16-bit wide organization maps directly onto a 16-bit MCU or DSP data bus, saving the byte-lane logic a narrower part would need.

This part carries an official lifecycle status of Obsolete. No last-time-buy window remains open through the original manufacturer. Sourcing is through independent distribution and surplus inventory only. That wider temperature grade may be acceptable for commercial designs and keeps the board spin zero.

Housed in a 44-pin TSOP II (0.400" body width, 10.16 mm wide), surface-mount package.

Frequently asked questions

What is the replacement for CY7C1021BNV33L-10ZXC?

It drops in without a board layout change.

CY7C1021BNV33L-10ZXC vs CY7C1021BNV33L-10ZXI difference?

Both share the same 44-TSOP II package, 10 ns speed, and 3.3 V supply.
