32 Mbit Quad-SPI Flash — 104 MHz, wide temp, active lifecycle
The Microchip SST26VF032B-104V/SM is a 32 Mbit Serial Quad I/O (SQI®) Flash memory from the SST26 SQI® series, organized as 4M x 8. It supports both standard SPI and Quad I/O interfaces at a clock frequency of 104 MHz, giving the host controller fast read throughput for code shadowing or data logging.
104 MHz Quad-SPI — read throughput and bus margin
In a typical execute-in-place (XIP) or memory-mapped SPI setup, that bandwidth keeps the CPU fed without stalling for wait states, provided the PCB trace length and termination are kept tight. The write cycle time per page is 1.5 ms, which is competitive for firmware updates or configuration storage — the page-program time is the bottleneck, not the erase.
Package and footprint — 8-SOIJ narrow-body
The surface-mount footprint is identical to a standard SOIC-8 narrow, so it drops onto existing SPI Flash pads without a layout change. The tube shipping medium is fine for prototype builds; production volumes typically move to tape-and-reel, so verify the reel option if you are ordering for a pick-and-place line.
