What the 170 MHz Cortex-M4F means on this footprint
The core runs at 170 MHz with a single-precision FPU, giving it headroom for motor-control FOC loops, digital power conversion, or sensor fusion algorithms that would strain a Cortex-M3 at similar clock rates. Program memory is 32 KB of Flash, backed by 32K x 8 SRAM — enough for a moderate application firmware plus a real-time OS tick and a few data buffers.
Temperature range and package — what they tell you about deployment
The exposed pad also provides a low-inductance ground return for the high-speed analog peripherals. With 11 channels of 12-bit ADC and four 12-bit DACs on-chip, you can close a current-sense and PWM loop without external converters — useful for a single-chip servo drive or a digitally controlled PSU.
Lifecycle and sourcing posture
For new designs, this is a safe selection from a lifecycle standpoint. As an independent distributor, we source this part against an RFQ. If you need a date-code trace or lot-level provenance for a quality audit, we can provide the chain of custody documentation.
