64 Mbit NOR Flash for automotive code storage
The S25FL064P0XMFA003: It communicates over a Quad-SPI interface at up to 104 MHz, giving you enough read bandwidth for code shadowing or execute-in-place firmware on a vehicle ECU.
Quad-SPI at 104 MHz — sizing the read throughput
The Quad I/O interface reads four bits per clock cycle. At 104 MHz, the 64 Mbit memory is organized as 8M x 8 bytes. Page write time is 3 ms.
Package and footprint — 16-SOIC wide-body
Lifecycle — active, no obsolescence concern
The product status is Active. The base product number is S25FL064, so future die shrinks or package changes would carry a different suffix — keep an eye on PCNs if you're planning a multi-year build.
