500 MHz Cortex-M7 — no on-chip Flash
Peripherals and I/O budget
44 general-purpose I/O lines are available, alongside a 15-channel 12-bit ADC, USB 2.0 OTG with PHY, and serial interfaces covering I²C, SPI, UART, SAI (audio), and SPDIF. The EBI/EMI bus supports parallel NOR Flash, SRAM, or PSRAM; for smaller code footprints a QSPI Flash on the FlexSPI controller saves pins.
