128 Mbit NOR flash for firmware and parameter storage
The S25FL128SDPBHI210 is a 128 Mbit NOR flash memory from the FL-S series, organized as 16M x 8 bits. It uses the SPI Quad I/O interface for efficient read and write operations at a 66 MHz clock frequency, making it suitable for code shadowing, firmware storage, and configuration data in embedded systems.
24-ball BGA footprint and board-fit
Housed in a 24-TBGA (thin fine-pitch ball grid array) package measuring 8 mm x 6 mm, the device places 24 balls on a 0.80 mm pitch. The small footprint conserves board space, but the BGA requires a multi-layer PCB with via-in-pad or dog-bone fan-out for the inner balls. Check the MSL rating before the reflow profile — a moisture-sensitive BGA that skips the bake can popcorn during soldering.
