133 MHz Quad-SPI — what it means for boot time
The S25FL128SAGBHM203: At 133 MHz clock frequency, the Quad I/O interface delivers sustained read throughput that keeps the host MCU fed during firmware shadowing or XIP execution. For a 128 Mbit device, this means the entire memory can be read in under 30 ms at full speed — relevant for OTA staging and fast boot sequences in automotive gateways or ADAS controllers.
Package and footprint: 24-BGA (8x6 mm)
The 0.8 mm ball pitch is layout-friendly for a 2-layer board, but keep the SPI traces length-matched and avoid vias on the clock line.
This is a current-production part that Infineon continues to manufacture for automotive programs.
