It uses a SPI interface with Quad I/O and QPI support, clocked at 66 MHz.
This part is listed as Obsolete per the manufacturer's lifecycle status.
66 MHz Quad SPI — bus margin and throughput
The 66 MHz clock frequency applies to the SPI Quad I/O interface, delivering read throughput suitable for code shadowing and data logging in automotive and industrial embedded systems. The Quad I/O mode reduces the number of command cycles compared to standard SPI, improving effective read bandwidth.
24-TBGA package — rework considerations
The 24-ball TBGA (6x8 mm) is a fine-pitch BGA. Rework requires a hot-air station with a nozzle sized for the 6x8 mm body. The package has no exposed thermal pad — all 24 balls are signal or power. Orientation is marked by pin-1 indicator on the package top.
