Product details

128Mbit NOR Flash in a 24-BGA footprint

The write cycle time is 5 µs per word and 3 ms per page, which matters when sizing the OTA staging area or logging sensor data at high frequency. The supply range of 2.7V to 3.6V covers both 3.3V nominal rails and the low end during battery discharge.

Industrial temperature grade — outdoor and factory use

The non-volatile NOR technology retains data through power loss, and the 128Mbit density is a common sweet spot for firmware images and configuration storage.

Frequently asked questions

What is a direct replacement for S25FL129P0XBHIZ03?

The FL-P series has been superseded by newer Cypress NOR Flash families, but pin-compatibility and software compatibility must be verified against the specific application. Check the S25FL128P series as a starting point for a drop-in candidate.
