PIC32MX220F032CT-V/TL Visão geral
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, programmable peripherals, and I/O into one package. The PIC32 family sits in Microchip's 32-bit portfolio above the 16-bit PIC24/dsPIC families and bridges the gap toward the ARM Cortex-M-based SAM products. Within the PIC32MX1xx/2xx series, the MX220 represents the entry-level tier focused on low pin count, USB-capable, and graphics/audio-friendly applications where MIPS-class performance is sufficient.
Key features include a five-channel 16-bit timer/counter block, two UART and two I2C modules, separate PLLs for CPU and USB clocks, up to four DMA channels with automatic data size detection, Peripheral Pin Select (PPS) for flexible signal routing, and a configurable Watchdog Timer with on-chip Low-Power RC oscillator. The device integrates multiple power management modes (Idle, Sleep) and supports 3.3V system designs typical of consumer, industrial, and automotive subsystems.
The M4K core implements the MIPS32r2 instruction set with hardware multiply/divide and a five-stage pipeline, achieving 1.56 DMIPS/MHz (approximately 60 DMIPS at 40 MHz). On-chip USB 2.0 full-speed OTG, comparators, and 10-bit ADC channels (up to 1 Msps) make this part well suited to sensor hubs, HMI panels, and USB peripherals. The 36-pin VTLA (Very Thin Leadless Array) package reduces PCB area while still exposing sufficient GPIO for mixed-signal designs.
Typical applications include USB HID peripherals, low-cost HMI keypads, sensor data acquisition, and automotive body electronics such as HVAC controls or lighting modules where AEC-Q100 and small package size are advantageous. Designers migrating from PIC16/PIC24 can scale up to MIPS-class code density without learning a new toolchain, thanks to MPLAB X IDE and Harmony compatibility.
When designing with this device, observe the 2.3 V minimum supply and provide bulk decoupling at VDD/AVDD plus 0.1 uF ceramics near each pin pair. The -V temperature grade supports automotive -40C to +125C operation, while PPS mapping must be locked before peripheral enable to prevent spurious interrupts on shared pins.

Aplicações típicas
PIC32MX220F032CT-V/TL é adequado para 6 aplicaçãos: USB HID Peripheral (Keyboard / Mouse / Gamepad), Automotive Body Electronics (HVAC, Lighting), Sensor Hub / Data Acquisition Front-End, Low-Cost HMI Keypad / Control Panel, Consumer Audio Accessory (USB Speaker / Headset), Industrial Control Module (RS-485 Gateway).
USB HID Peripheral (Keyboard / Mouse / Gamepad)
The PIC32MX220F032CT-V/TL is a strong fit for USB HID peripherals thanks to its integrated USB 2.0 Full-Speed OTG transceiver, separate USB PLL for 48 MHz clock generation, and 8 KB SRAM which is adequate for HID report buffers plus stack overhead. The 34 GPIO comfortably support key matrices, scroll wheels, RGB LEDs, and I2C sensor hubs. With the -V AEC-Q100 grade, HID peripherals can be deployed in automotive cabin accessories such as steering-wheel controls. The 5x5 mm VTLA-36 footprint keeps PCB area under 50 mm^2, and the MIPS toolchain via MPLAB Harmony provides ready-made USB HID class drivers.
Recomendado
Automotive Body Electronics (HVAC, Lighting)
The PIC32MX220F032CT-V/TL targets automotive body modules with its AEC-Q100 Grade 1 (-40C to +125C) qualification and 32 KB Flash that supports small RTOS or stateflow firmware for HVAC flap control, ambient lighting, and headlamp leveling. The two UART and two I2C peripherals handle LIN transceivers, NTC thermistor networks, and LED driver ICs. PPS allows reassigning I2C/SPI/UART to alternate pins without board re-spin. The 5x5 mm VTLA package is suitable for the constrained PCB area of in-cabin control modules, and separate CPU/USB PLLs prevent jitter coupling between control loops and diagnostic links.
Recomendado
Sensor Hub / Data Acquisition Front-End
The PIC32MX220F032CT-V/TL works well as a low-cost sensor hub thanks to its 10-bit ADC (up to 1 Msps), five 16-bit timers for precise PWM excitation, and DMA channels that move ADC samples to SRAM without CPU intervention. With 8 KB SRAM, the MCU can hold several hundred samples before forwarding them over UART or I2C to a host processor. The 40 MHz M4K core executes digital filters at >1 Msps, and PPS lets the designer route ADC triggers and PWM outputs to any GPIO. The -V temp grade qualifies the part for outdoor industrial sensor installations.
Recomendado
Low-Cost HMI Keypad / Control Panel
The PIC32MX220F032CT-V/TL is ideal for compact HMI panels such as appliance keypads, access-control readers, and small appliance control boards. The 34 GPIO can scan up to a 5x6 key matrix plus drive a character LCD or small OLED over SPI, all without external logic. PWM outputs controlled by the 16-bit timers enable smooth LED backlight dimming, and the on-chip comparators detect key-press events without ADC conversion overhead. PPS provides flexible signal routing so the keypad PCB layout is not constrained by fixed peripheral pin assignments.
Recomendado
Consumer Audio Accessory (USB Speaker / Headset)
The PIC32MX220F032CT-V/TL can act as a USB Audio Class 1.0 controller in low-cost USB speakers, headsets, and DAC dongles. The separate USB PLL guarantees 48 kHz/44.1 kHz sample-rate accuracy, and DMA moves audio samples to an external I2S DAC with low CPU load. With 8 KB SRAM, the part handles USB descriptors, HID volume buttons, and basic LED feedback. The 36-pin VTLA footprint is small enough for in-line dongle enclosures. Designers using MPLAB Harmony USB Audio stack can deploy reference firmware in days.
Recomendado
Industrial Control Module (RS-485 Gateway)
The PIC32MX220F032CT-V/TL fits compact industrial RS-485 / Modbus gateway designs where its two UARTs bridge a host controller to a field bus, while the two I2C ports manage local sensors. AEC-Q100 -V grade tolerates factory-floor thermal stress, and PPS lets the same hardware platform support either RS-485 or RS-232 by remapping UART pins. The 5x5 mm VTLA-36 footprint simplifies integration into small DIN-rail enclosures. 8 KB SRAM and DMA support efficient Modbus RTU buffer handling under interrupt load.

Principais diferenciais
- Smallest 36-pin VTLA footprint in the PIC32MX220 family (vs PIC32MX220F032B-V/SS)
- AEC-Q100 Grade 1 automotive qualification (vs PIC32MX220F032CT-I/TL)
- MIPS M4K core at 40 MHz with USB OTG (vs PIC32MX120F032C-I/TL)
Notas de projeto
Estimated: At 40 MHz with all peripherals active and USB enabled, core current is approximately 30 mA at 3.3 V. Add 8 mA for USB transceiver when active. Total worst-case 3.3 V rail consumption is roughly 38 mA, which an LDO such as MCP1700 (250 mA) supplies comfortably. Place a 10 uF bulk plus 0.1 uF ceramic near each VDD/AVDD pin to suppress switching transients from DMA and USB activity.
The 36-pin VTLA package uses 0.5 mm pitch leadless pads and requires PCB land patterns per Microchip package specification. Add 0.5 mm-wide traces with 0.2 mm clearance, and ensure the central thermal pad (if any) has at least 8 thermal vias to the inner ground plane to keep junction temperature within the 125 C automotive limit. Avoid running noisy USB or PWM traces directly under analog ADC inputs to prevent coupled noise.
Do not exceed 3.6 V on any VDD/AVDD pin or 5 V on VBUS without external clamping - USB VBUS expects 5 V tolerant input. Lock all PPS mappings before enabling peripherals; unlocked PPS can route conflicting functions and trigger undefined interrupts. For automotive deployments, configure the on-chip LPRC-backed WDT and use the Fail-Safe Clock Monitor (FSCM) to recover from primary oscillator failure.
