It has 1 MB Flash and 256K x 8 SRAM.
120 MHz Cortex-M4F — what it buys you
The 120 MHz core with an FPU lets you close a current-control loop at several kilohertz and still have headroom for Ethernet packet handling. The 24-channel 12-bit ADC samples synchronously with the PWM timers — useful for three-phase motor current sensing without software jitter.
Connectivity and I/O budget
The USB OTG port can act as a device for firmware updates or as a host for a USB flash drive logging data.
The 212-NFBGA (10x10) package is a fine-pitch BGA. Expect four-layer minimum PCB with via-in-pad or microvia for the center balls.
