32 Mbit NOR flash with 108 MHz quad I/O
This is a 32 Mbit (4M x 8) SPI NOR flash from the FL1-K series, organized as 4M x 8 bits. The memory interface supports SPI Quad I/O at a clock frequency of 108 MHz, giving a read throughput that suits code shadowing and firmware storage in an automotive ECU. The 108 MHz quad-I/O rate means the part can sustain a sequential read fast enough to feed a Cortex-M or similar MCU's cache without wait states on a 4-bit bus — a practical fit for boot memory or data logging where the NOR's fast random access matters.
8-SOIC package and board fit
The surface-mount package reflows on a standard SOIC land pattern and is hand-solderable for prototyping. Write cycle time is 3 ms typical per word or page — budget this into the firmware update routine; a full 32 Mbit erase and reprogram cycle will take several seconds at the page level.
