PIC32MX220F032DT-V/TL Présentation
A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, and configurable peripherals used to sense, control, and communicate in embedded systems. The PIC32MX220F032D belongs to the wider 32-bit MCU category (MIPS32/M4K -> 32-bit RISC -> microcontroller -> embedded IC -> semiconductor) and is targeted at cost-sensitive connected and human-machine-interface designs that previously required 16-bit or external USB solutions.
Key features include 34 general-purpose I/O lines, a 13-channel 10-bit analog-to-digital converter, five 16-bit timers/counters, four DMA channels, two UART modules, two I2C buses, two SPI/I2S peripherals, and a Charge Time Measurement Unit (CTMU) for mTouch capacitive touch sensing. The chip operates from 2.3 V to 3.6 V and supports industrial temperature ranges from -40 C to +105 C.
Architecturally, the M4K core delivers 1.56 DMIPS/MHz (about 62 DMIPS at 40 MHz) with single-cycle hardware multiply and divide, while separate PLLs for the system clock and USB clock allow the CPU and USB peripheral to run at independent frequencies without compromising timing margins. PPS remapping lets designers route any digital peripheral to most I/O pins, simplifying PCB layout.
Typical applications include USB peripherals (HID, CDC, mass storage, audio), automotive infotainment and body controllers, capacitive touch human-machine interfaces, low-cost graphics with PMP-driven TFT panels, industrial control with Modbus/CAN bridging, and consumer audio docks that require I2S codec connectivity.
When designing with this part, observe that 40 MHz operation requires VDD >= 2.3 V and that USB transceiver compliance depends on a precision 48 MHz PLL reference. Use the MPLAB XC32 compiler and MPLAB Harmony framework for firmware development.

Applications typiques
PIC32MX220F032DT-V/TL convient pour 6 applications: USB HID Peripherals, Automotive Body Controllers, Capacitive Touch HMI, Audio Docks / USB Speakers, Low-Cost Graphics with PMP, Industrial Control / Modbus Bridge.
USB HID Peripherals
The PIC32MX220F032DT-V/TL's integrated USB 2.0 Full-Speed OTG controller with a dedicated 48 MHz PLL makes it ideal for USB Human Interface Devices such as keyboards, mice, game controllers, and custom HID peripherals. The 40 MHz M4K core provides enough headroom to run USB stacks (Microchip USB framework or TinyUSB port) while leaving CPU cycles for application logic, and 32 KB Flash fits typical HID report descriptors plus composite device firmware. The automotive -V grade enables direct deployment in cabin controllers and steering-wheel switch panels.
Recommandé
Automotive Body Controllers
The AEC-Q100 qualification and -40 C to +105 C operating range make the PIC32MX220F032DT-V/TL well suited for automotive body and chassis ECUs controlling lighting, mirror actuators, door modules, and seat controllers. The CTMU peripheral enables mTouch capacitive touch sensing for smart entry panels and overhead consoles. With 34 GPIO and PPS flexibility, engineers can route LIN, PWM fan control, and switch-scan inputs without an external I/O expander, and 8 KB SRAM comfortably hosts LIN scheduler and lighting state-machine firmware.
Recommandé
Capacitive Touch HMI
The integrated Charge Time Measurement Unit (CTMU) plus the mTouch library allow the PIC32MX220F032DT-V/TL to scan 13+ capacitive touch electrodes with sliders and buttons at low power. The 40 MHz core executes CTMU charge-time measurements and touch decoding in under 200 us per scan cycle, leaving the rest of the duty cycle for backlight PWM, LED driving, and a USB HID host interface for diagnostic logging. The AEC-Q100 grade supports direct deployment behind automotive touch panels.
Recommandé
Audio Docks / USB Speakers
Two I2S/SP I modules and USB 2.0 OTG make the PIC32MX220F032DT-V/TL a natural fit for USB audio docks that stream PCM from a PC or phone to an external DAC. One I2S bus handles the external audio DAC, while the second SPI can drive an EEPROM for device descriptors or a display controller. 8 KB SRAM accommodates double-buffered USB audio isochronous packets at 48 kHz / 16-bit, and 32 KB Flash fits the USB audio class driver plus basic volume-control firmware.
Recommandé
Low-Cost Graphics with PMP
The Parallel Master Port (PMP) on the PIC32MX220F032DT-V/TL can drive small TFT displays (up to 8-bit parallel RGB) directly, eliminating an external graphics controller. With 40 MHz core speed and DMA-assisted PMP transactions, the device can refresh 320x240 QVGA panels at sufficient rates for menu UIs, appliance front panels, and medical device displays. PPS lets the designer remap display data lines to free GPIO for keypad scanning.
Recommandé
Industrial Control / Modbus Bridge
Two UARTs and two I2C buses on the PIC32MX220F032DT-V/TL enable it to act as a Modbus RTU bridge between RS-485 sensor networks and an I2C sensor cluster, with a USB CDC channel for local configuration via a host PC. The AEC-Q100 -V grade allows deployment in industrial cabinets that must also meet automotive-style temperature specs. 8 KB SRAM handles Modbus PDU buffering for typical sensor polls.

Principaux différenciateurs
- AEC-Q100 automotive grade in the smallest Flash configuration (vs PIC32MX220F032DT-I/TL)
- USB 2.0 Full-Speed OTG with dedicated 48 MHz PLL (vs PIC32MX130F256DT-V/TL)
- Peripheral Pin Select (PPS) flexibility (vs PIC32MX210F016DT-I/TL)
Notes de conception
The PIC32MX220F032DT-V/TL requires a regulated 2.3V to 3.6V supply. Place a 100 nF decoupling capacitor as close as possible to each VDD pin (six pins on the VTLA-44 package) plus a bulk 10 uF tantalum or ceramic capacitor near the package. Connect all VSS pins to a single solid ground plane. The VUSB pin needs its own 100 nF + 4.7 uF capacitor network for USB transceiver stability even if USB is unused.
The VTLA-44 package has a center thermal pad on the underside that must be soldered to a copper pad on the PCB for mechanical reliability and thermal dissipation. Although the M4K core at 40 MHz dissipates less than 100 mW in typical applications, soldering the center pad avoids leadless-package solder-joint fatigue under thermal cycling. Use a 0.65 mm pitch land pattern per Microchip's VTLA-44 recommended footprint.
Three pitfalls to avoid: (1) the 48 MHz USB PLL requires a precision 8 MHz or 12 MHz crystal - an RC oscillator will fail USB compliance; (2) PPS remapping must be configured before enabling peripherals, or the peripheral pins will float; (3) entering Sleep mode without disabling the ADC will leave the ADC biased and increase wake-up current - disable the ADC in the PMD register before sleep.
Estimated: at 40 MHz core clock and full peripheral activity, the M4K core dissipates roughly 30 mA * 3.3 V = 100 mW. With the VTLA-44 theta_JA around 35 C/W (typical for 6x6 mm leadless packages on a 2 oz 4-layer PCB), junction temperature rise above ambient is approximately 100 mW * 35 C/W = 3.5 C - well within the -40 C to +105 C automotive range, even without a heatsink.
