Product details

80 MHz Cortex-M4 with FPU — processing headroom for sensor fusion

With 38 I/Os, a 10-channel 12-bit ADC, and dual 12-bit DACs, it handles analog sensor acquisition and output without external converters.

Connectivity and peripherals — CAN, USB, QSPI, SAI on a single chip

The peripheral set includes CANbus for industrial networks, USB for device connectivity, QSPI for external Flash expansion, and SAI for audio interfaces. Brown-out detect/reset, DMA, LCD driver, PWM, and WDT round out the system functions.

Package and temperature grade — 48-UFQFPN with exposed pad

No last-time-buy or obsolescence risk for production planning.
