256 Mbit NOR Flash with Quad-SPI — what the specs mean for the design
The S25FL256SDPBHIC13: It is a non-volatile memory device intended for code storage, firmware updates, and data logging in embedded systems that need a moderate-density, fast-read NOR Flash. The Quad-SPI interface at a 66 MHz clock rate delivers sustained read throughput that can keep up with many MCU SPI peripherals for execute-in-place (XIP) or rapid boot sequences.
66 MHz Quad-SPI — read throughput and bus margin
The 66 MHz clock frequency is the maximum SPI clock for Quad I/O reads.
Package and footprint: 24-BGA (8x6 mm)
The S25FL256SDPBHIC13 comes in a 24-ball BGA package (supplier device package 24-BGA, 8 mm x 6 mm).
