PIC32MX210F016DT-V/ML Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), working memory (SRAM), and programmable peripherals into one package. The PIC32MX family sits in the hierarchy microcontroller -> 32-bit MCU -> MIPS-based MCU -> embedded controller, and is purpose-designed for low-power, mixed-signal embedded applications such as USB peripherals, capacitive touch interfaces, and cost-sensitive consumer or industrial control. PIC32MX devices serve as representative variants in Microchip's 32-bit MCU portfolio, balancing performance, peripheral integration, and low BOM footprint.
The PIC32MX210F016DT-V/ML achieves less than 0.5 mA/MHz active current consumption with multiple low-power modes (Sleep, Idle, Doze) enabled via Peripheral Pin Select (PPS) mapping. Hardware DMA to feature external memory interfacing and 5-mips fan-out cycles. Two UART and I2C modules serve asynchronous IO. Pin-select enables two I2S modules for Codec and serial communications. With 16 KB Flash and 4 KB SRAM, the platform is well-suited for cost-sensitive USB peripherals, capacitive-touch embedded applications.
Typical applications include USB audio peripherals, mTouch capacitive touch buttons and sliders, low-cost graphics terminals via PMP, and industrial control interfaces. The wide 2.3 V to 3.6 V supply range simplifies designs powered directly from a USB rail or 3.3 V LDO.
Designers should ensure the exposed thermal pad is soldered to a sufficient ground plane for thermal dissipation, and follow Microchip's PIC32MX USB flash requirements (e.g., 12 MHz crystal with appropriate load capacitors) when enabling the USB peripheral. The wide voltage tolerance enables direct USB power-supply usage.

Design Notes
The 44-pin QFN (ML) 8x8 mm package has an exposed thermal pad on the bottom side that must be soldered to a ground plane for thermal dissipation and electrical grounding. Per the Microchip PIC32MX1xx/2xx packaging specification, at least 8 thermal vias in the exposed pad are recommended to connect to inner ground planes. For a QFN device dissipating less than 0.5 mA/MHz active current, ignore the thermal pad and the device will lock at high speeds due to inadequate thermal paths.
Place a 100 nF decoupling capacitor as close as possible to each VDD pin (there are 2 VDD pins on the 44-QFN layout). Add a single 4.7 uF bulk capacitor near the supply entry point. The PIC32MX210 operates from 2.3 V to 3.6 V; for USB applications, the 3.3 V rail must be regulated to within ±5% to meet USB 2.0 FS signaling requirements. According to the PIC32MX1xx/2xx datasheet, do not power the VDD > 3.6 V or the device will lock at high speeds due to overvoltage stress.
For USB operation, use a 12 MHz external oscillator (HSUSB mode) with appropriate load capacitors per the crystal datasheet. Do not enable USB on the internal 8 MHz FRC oscillator without external frequency-locked loop (FLL) calibration, or USB enumeration will fail. According to the Microchip PIC32MX1xx/2xx family datasheet, the 48 MHz USB clock is derived from the primary oscillator via the on-chip PLL; lock the primary oscillator frequency accuracy to within ±0.25% for reliable USB enumeration at full-speed.
Route the 12 MHz crystal traces symmetrically and keep them short (<5 mm) with grounded guard traces to minimize EMI. Place the crystal load capacitors within 2 mm of the crystal pins. Per the Microchip PIC32MX1xx/2xx layout guidelines, route the USB D+/D- traces as a 90-ohm differential pair with matching lengths to within 150 mil; route VSS beneath the D+/D- pair to provide a reference plane.
Compliance Information
RoHS compliant per Microchip product page. Lead-free (Pb-free) reflow profile per JEDEC J-STD-020. AEC-Q100 not qualified - the V-grade -40 °C to +105 °C range supports industrial but not automotive safety-critical use cases.
