PIC32MX210F016DT-I/PT Overview
A 32-bit microcontroller (MCU) is a single-chip computer that integrates a 32-bit processor core, program memory (Flash), data memory (SRAM), and a rich set of peripherals including timers, communication interfaces, and analog blocks. The PIC32MX2xx family sits within the broader PIC32MX hierarchy (8-bit PIC -> 16-bit PIC24/dsPIC -> 32-bit PIC32 -> 32-bit MIPS-based PIC32MX -> M4K core family -> USB-enabled sub-family), giving designers an upgrade path from 8-bit legacy PIC code while retaining the familiar MPLAB X toolchain. The M4K core is a Harvard-architecture 5-stage pipeline processor, and the PIC32MX210F016D variant adds USB 2.0 full-speed device support alongside two I2S/SPI modules for codec interfacing.
Key features of the PIC32MX210F016DT-I/PT include Peripheral Pin Select (PPS) for flexible I/O mapping, a Parallel Master Port (PMP) for graphics and external memory interfaces, a Charge Time Measurement Unit (CTMU) for mTouch capacitive touch sensing, five 16-bit timers, and a 10-bit ADC with up to 13 input channels. The integrated USB 2.0 full-speed device controller makes this part particularly suited to embedded USB applications. DMA channels accelerate data movement between peripherals and memory without CPU intervention, and a Real-Time Clock and Calendar (RTCC) is included for timekeeping applications.
Typical applications for this device include USB peripherals (HID, CDC, vendor-class), consumer audio devices with I2S codec support, capacitive touch user interfaces using CTMU, low-cost graphics interfaces via PMP, industrial control, and sensor hubs. Its compact 44-TQFP footprint and standard JTAG/ICSP programming interface simplify PCB layout and in-system firmware updates.
When designing with this part, allocate sufficient decoupling (100 nF ceramic near each VDD pin plus a bulk 4.7-10 uF), follow Microchip's USB hardware design guidelines for the D+/D- traces, and use the MPLAB Harmony framework for USB stacks and peripheral drivers. The 'D' suffix indicates tray packaging, and the 'T' indicates tape-and-reel carrier when ordered in that format.

Typical Applications
PIC32MX210F016DT-I/PT is suitable for 6 applications: USB Human Interface Device (HID) Peripherals, Capacitive Touch User Interfaces, Consumer Audio with I2S Codec, Industrial Sensor Hubs and Data Loggers, USB CDC Virtual COM Port Devices, Low-Cost Graphics with PMP Interface.
USB Human Interface Device (HID) Peripherals
The PIC32MX210F016DT-I/PT integrates a USB 2.0 full-speed device controller with on-chip transceiver, making it a natural fit for HID-class USB peripherals such as keyboards, mice, game controllers, and custom input devices. The 40 MHz M4K core delivers 66 DMIPS, sufficient to handle USB polling intervals of 1 ms while leaving CPU headroom for HID report parsing, debounce logic, and RGB LED control via PWM. With 16 KB Flash and 4 KB SRAM, designers can implement a complete HID stack plus Microchip's MLA USB library within budget. The 44-TQFP package keeps PCB area minimal, and the PPS system allows USB D+/D- to be remapped if layout constraints require it.
Recommended
Capacitive Touch User Interfaces
The integrated Charge Time Measurement Unit (CTMU) enables hardware-accelerated capacitive touch sensing for mTouch buttons, sliders, wheels, and proximity sensors without external touch ICs. Combined with the 10-bit ADC and 5x 16-bit timers, the PIC32MX210F016DT-I/PT can scan up to 13 touch channels while running the USB CDC stack for diagnostic reporting. The 16 KB Flash accommodates Microchip's mTouch libraries and a small RTOS for multi-touch gesture recognition. The -40C to +85C industrial temperature range supports appliances, white goods, and automotive aftermarket products where touch interfaces replace mechanical buttons.
Recommended
Consumer Audio with I2S Codec
Two I2S/SPI modules allow direct interfacing to external audio codecs for digital audio playback, Bluetooth audio sink bridging, or sound effect generation. The PIC32MX210F016DT-I/PT's DMA channels move audio samples between I2S and SRAM without CPU intervention, freeing the M4K core for audio processing or USB streaming at the same time. While 4 KB SRAM limits buffer depth for high-fidelity audio, it is adequate for low-bit-rate voice prompts, notification chimes, or 16 kHz mono audio streaming. The PMP interface can also drive small LCD displays for audio product UIs.
Recommended
Industrial Sensor Hubs and Data Loggers
With 5x 16-bit timers, 2x UART, 2x I2C, 2x SPI, and a 10-bit ADC with up to 13 channels, the PIC32MX210F016DT-I/PT serves as a compact sensor hub aggregating data from temperature sensors, accelerometers, pressure transducers, and digital interfaces. DMA offloads data movement, while the RTCC provides accurate timestamping for logged events. The 16 KB Flash holds a lightweight file system or ring buffer logger for SD card offload via SPI. The industrial -40C to +85C temperature rating suits factory floor, HVAC, and outdoor cabinet installations.
Recommended
USB CDC Virtual COM Port Devices
The PIC32MX210F016DT-I/PT implements USB CDC class devices for virtual COM port bridges, firmware update channels, and configuration interfaces. Microchip's MLA USB library provides ready-made CDC stacks occupying roughly 6-8 KB of Flash, leaving headroom in the 16 KB Flash for application logic. The 40 MHz core handles 115200 bps and higher CDC line coding transparently. Common applications include USB-to-UART bridges, USB dataloggers with PC-side plotting, and USB configuration tools for industrial controllers.
Recommended
Low-Cost Graphics with PMP Interface
The Parallel Master Port (PMP) on the PIC32MX210F016DT-I/PT can drive small parallel TFT or OLED displays (typically up to 320x240 with external frame buffer) for simple graphical UIs. The 4 KB SRAM is sufficient for a partial frame buffer or character/UI element rendering. Combined with CTMU for touch input and USB for configuration download, the part forms a complete low-cost HMI platform for appliances, thermostats, and small industrial control panels. The 44-TQFP package keeps BOM cost down compared to larger 64-pin and 100-pin PIC32 variants.

Key Differentiators
- Integrated USB 2.0 full-speed device with on-chip transceiver (vs PIC32MX110F016DT-I/PT)
- Automotive AEC-Q100 grade option in identical footprint (vs PIC32MX210F016DT-I/PT (industrial))
- Compact 44-TQFP package with 34 I/O pins (vs Larger 64-pin or 100-pin PIC32MX variants)
Design Notes
Decouple each VDD pin with a 100 nF ceramic capacitor placed within 5 mm of the pin, and add a single 4.7-10 uF bulk capacitor on the board. Connect VUSB (pin 15) to 3.3 V even if USB is not used, per Microchip errata, to prevent unwanted current draw through the USB transceiver. AVDD (pin 10) should be tied to VDD with its own 100 nF + 10 uF decoupling pair to keep ADC measurements clean.
USB D+ and D- traces must be 90 ohm differential with matching length (within 150 mil) and routed over a continuous ground plane. Place the 15 kohm pull-down on D- near the MCU pin. The crystal oscillator traces (OSC1/OSC2) should be short and guarded by ground to minimize EMI. Avoid routing digital signals under the crystal traces or the AVDD/AVSS pair.
Do not confuse 'DT' (tape-and-reel suffix) with separate die variants. Always check the full ordering code: 'I' = industrial temp, 'PT' = 44-TQFP package, 'D' = die revision. For automotive applications, use the 'V' suffix part (e.g., PIC32MX210F016BT-V/PT) which is AEC-Q100 qualified. Programming via ICSP requires the PGED2/PGEC2 pair on pins 8-9 of this 44-TQFP variant.
Compliance Information
RoHS and REACH compliant per Microchip product page. The 'I' industrial temperature variant is not AEC-Q100 qualified; for automotive use, choose the 'V' suffix variant (PIC32MX210F016BT-V/PT) which is AEC-Q100 qualified.
