PIC32MX210F016D-I/TL Overview
A PIC32MX microcontroller is a 32-bit RISC MCU built on the MIPS32 M4K core, belonging to the broader PIC32 family of flash microcontrollers. PIC32MX sits between Microchip's 16-bit PIC24/dsPIC family and the higher-performance PIC32MZ family, offering 32-bit performance with sub-1 mA/MHz active current consumption and a Peripheral Pin Select (PPS) routing fabric that allows remapping of digital peripherals to most I/O pins. This places PIC32MX210F016D firmly inside the '32-bit MCU > flash microcontroller > embedded microcontroller' taxonomy.
Key differentiating features include hardware DMA (up to 4 channels with automatic data-size detection), five 16-bit general-purpose timers plus up to two 32-bit timers, two UART modules, two I2C modules, two I2S/SPI modules, a USB 2.0 full-speed device peripheral with dedicated PLL, a 10-bit 1 Msps ADC, a Parallel Master Port (PMP) for graphics, and a Charge Time Measurement Unit (CTMU) for capacitive touch sensing. The 34 I/O pins support PPS remapping for flexible PCB routing.
The architecture pairs a single-cycle MIPS32 M4K core with separate PLLs for the CPU and USB clock domains, allowing the USB peripheral to operate at the precise 48 MHz required by USB 2.0 full-speed while the CPU runs up to 40 MHz for application code. The CTMU, combined with the ADC, provides accurate time-domain touch measurement for mTouch capacitive-button and proximity-sensing applications, while PMP enables direct connection to graphics TFT displays.
Typical applications include USB HID devices such as custom keyboards, mice, and game controllers, low-cost audio peripherals with USB streaming, capacitive touch user interfaces using mTouch, low-resolution graphics TFT panels driven via PMP, and low-power sensor nodes that benefit from the PIC32's deep-sleep and idle modes. The 2.3 V minimum supply supports single-cell Li-ion or two-AA battery rails.
When designing with this part, reserve the dedicated USB DP/DM pins (and route the D+/D- pair as a 90-ohm differential), connect the VCAP pin to a 10 uF decoupling capacitor, and configure the programming/debug pair using the PPS-aware PGECx/PGEDx pairs documented in the datasheet. The I/TL suffix indicates the industrial temperature range (-40C to +85C) and VTLA tube packaging.

Typical Applications
PIC32MX210F016D-I/TL is suitable for 6 applications: USB HID Device (Keyboard/Mouse/Gamepad), USB CDC Virtual COM Port / Data Logger, mTouch Capacitive Touch Button Interface, Low-Resolution Graphics TFT Panel via PMP, Battery-Powered Wireless Sensor Node, Industrial Sensor Interface / 4-20 mA Loop Powered.
USB HID Device (Keyboard/Mouse/Gamepad)
The PIC32MX210F016D-I/TL fits USB HID device designs because it integrates a USB 2.0 full-speed peripheral with a dedicated 48 MHz USB PLL on the same die, eliminating the need for an external USB clock crystal or PHY. With 16 KB Flash, the part can comfortably host Microchip's USB HID bootloader, USB HID stack, and application firmware for low-rate keyboard, mouse, or gamepad designs. The 4 KB SRAM is enough for HID report buffers up to four concurrent interface reports. The 40 MHz MIPS32 M4K core runs the USB stack plus HID scanning at low loop overhead, while 34 I/O pins via Peripheral Pin Select (PPS) allow direct matrix-scanning key wiring without an I/O expander. Place a 10 uF VCAP capacitor and route the 90-ohm D+/D- differential pair per USB 2.0 specification.
Recommended
USB CDC Virtual COM Port / Data Logger
For USB-to-UART bridge designs and USB-based data loggers, the PIC32MX210F016D-I/TL provides the necessary USB 2.0 full-speed device peripheral and a pair of UART modules to bridge USB CDC to an external RS-232/RS-485 transceiver. The 40 MHz M4K core handles USB enumeration, CDC ACM class driver, and UART TX/RX DMA transfers without measurable CPU load, while the 4-channel DMA controller offloads CDC TX/RX ring-buffer management. With 16 KB Flash, the part can host Microchip's USB CDC stack, a small RTOS, and sensor sampling routines. PPS allows remapping of UART TX/RX pins to optimize PCB routing of the UART-to-RS-485 transceiver path.
Recommended
mTouch Capacitive Touch Button Interface
The PIC32MX210F016D-I/TL's integrated Charge Time Measurement Unit (CTMU), 10-bit 1 Msps ADC, and 16 KB Flash make it ideal for mTouch capacitive-touch button, wheel, and slider interfaces. The CTMU pairs with the ADC to perform time-domain charge measurement on each touch electrode, supporting 4-12 touch buttons per PCB without external components. The 40 MHz M4K core can scan a 12-button matrix at >100 Hz refresh rate, while PPS routes the CTMU output to any of the 34 I/O pins for ergonomic PCB placement of electrodes. Industrial-grade -40C to +85C operation supports appliance, HVAC, and industrial front-panel designs.
Recommended
Low-Resolution Graphics TFT Panel via PMP
For small graphics TFT panels (up to 3.5" QVGA), the PIC32MX210F016D-I/TL's Parallel Master Port (PMP) directly interfaces to 8/16-bit TFT controllers without external logic, enabling low-cost graphical UIs on appliances, white goods, and instrument panels. The 40 MHz M4K core and dedicated PMP DMA channel sustain 320x240 QVGA refresh at 30+ fps from 16 KB Flash-resident frame buffers and compact UI assets. PPS allows remapping of PMP data/control lines for flexible TFT connector routing, while 2.3 V minimum VDD supports single-cell Li-ion battery-powered portable instruments. The 6x6 mm VTLA package fits in compact handheld instrument layouts.
Recommended
Battery-Powered Wireless Sensor Node
For battery-powered wireless sensor nodes, the PIC32MX210F016D-I/TL's sub-1 mA/MHz active current, 2.3 V minimum VDD (single-cell Li-ion or 2-AA compatible), and deep-sleep/idle modes allow years of standby operation on small battery packs. Pair the MCU with a 2.4 GHz transceiver (such as Microchip's MRF24J40 or RN2483 LoRa module) over SPI for MCU control; the 40 MHz M4K core runs sensor sampling, encryption, and stack tasks, while 16 KB Flash holds a small sensor stack. CTMU can also be used for proximity-sensor wake-up events. PPS allows SPI and interrupt lines to be remapped for clean PCB layout of the RF section.
Recommended
Industrial Sensor Interface / 4-20 mA Loop Powered
For industrial sensor analog front-ends and 4-20 mA loop-powered transmitters, the PIC32MX210F016D-I/TL's 10-bit 1 Msps ADC, 4-channel DMA, and -40C to +85C industrial temperature range provide accurate multi-channel sensor measurements in harsh environments. The 40 MHz M4K core runs sensor linearization, digital filtering, and a HART or analog 4-20 mA output loop in real time. DMA offloads ADC sampling sequences to keep the CPU free for HART modem signal generation. The 16 KB Flash holds the linearization table and small HART stack. The 6x6 mm VTLA package fits compact loop-powered transmitter PCBAs.

Key Differentiators
- Lowest-cost PIC32MX with USB 2.0 FS in 6x6 mm VTLA-44 footprint (vs PIC32MX210F016D-I/ML)
- Same VTLA-44 footprint with 100% more Flash and SRAM headroom (vs PIC32MX220F032D-I/TL)
- True PIC32MX210 variant with identical specifications for second-source flexibility (vs PIC32MX210F016D-I/PT)
Design Notes
PIC32MX210F016D-I/TL integrates a 1.25 Vcore regulator that requires a 10 uF decoupling capacitor on the VCAP pin (pin 44) for stable operation. The internal regulator sources up to ~50 mA for the digital core; place the VCAP capacitor within 5 mm of the pin with a wide trace to ground. Multiple VDD/VSS pin pairs (3, 25, 30/2, 10, 24, 31, 43) must each have a 0.1 uF ceramic bypass capacitor placed close to the pin to handle digital switching transients.
Route the USB D+ (RC5) and D- (RC4) signals as a 90-ohm differential pair to a USB Type-B or Mini-B connector, keeping the trace length under 50 mm to maintain signal integrity at USB 2.0 full-speed (12 Mbps). Place a 15 kohm pull-down resistor on D- and a 1.5 kohm pull-up resistor on D+ to signal device speed on enumeration. Use a common-mode choke (such as ACM2012) to pass conducted/radiated EMI compliance testing.
Do not skip configuring the PIC32CMX's Configuration Words (DEVCFG0/1/2/3) at startup - leaving defaults active will keep the JTAG enabled, the watchdog timer active, and the PLL in an undefined state. Use code initialization to disable JTAG if not needed, enable PLL for 40 MHz operation, and disable unused peripherals to save power. The Peripheral Pin Select (PPS) registers must be unlocked by writing a specific sequence to RPCON before remapping any peripheral to a non-default pin.
Estimated: PIC32MX210F016D-I/TL's VTLA-44 package has a theta_JA of approximately 35-40 C/W on a 4-layer JPC with standard copper. At 40 MHz active across 2.3-3.6 V supply, the part draws up to ~40 mA active current, dissipating ~100 mW at 3.3 V. This results in a modest 4C junction temperature rise - no heatsink required. In deep-sleep mode, current drops to ~30 uA, supporting years of battery standby operation.
