To help developers reduce system cost, design complexity and component count, the Precision32 family offers an exceptionally high level of peripheral integration that can enable a bill of materials (BOM) savings of up to $1.34 (USD). The following on-chip peripherals greatly reduce component count and system cost:
- Integrated precision oscillators with an advanced phase-locked loop (PLL) eliminate the need for a costly 8 MHz crystal by providing the clocking accuracy necessary for crystal-less USB operation while running the core independently at any frequency from 1 to 80 MHz.
- An internal 5 V voltage regulator enables the MCU to be powered directly from USB or a 5 V source without the need for an external regulator.
- Six high-drive I/Os (up to 300 mA each) can directly drive high-power LEDs, small motors, buzzers and power MOSFETs, as well as serve as a boost converter controller.
- Up to 16 capacitive touch channels eliminate the need for separate touch sensor ICs in applications requiring buttons, sliders or wheels.
- The Precision32 family offers a complete USB 2.0 PHY and analog front-end interfacing directly to the USB connector, while most other MCUs require an external USB pull-up resistor and termination circuit.
