50 MHz core — what it means for the control loop
At 50 MHz the Cortex-M3 executes single-cycle multiply and hardware divide. The 4-channel 10-bit ADC samples at a rate that keeps up with a PID loop.
Temperature grade and environment
Rated -40 to 105 °C, this MCU is suited for outdoor telecom cabinets, engine-bay electronics, and factory-floor controllers. The 48-VQFN exposed pad requires a thermal via pattern under the package.
Lifecycle and sourcing reality
The lifecycle record shows conflicting signals: one source flags this part as eol_hot, while another lists it as Active. We source it through independent distribution and quote to order against an RFQ.
