PIC32MX220F032B-V/SS Übersicht
A 32-bit microcontroller (MCU) is a single-chip computer that combines a 32-bit processor core, program memory, data memory, and a rich set of on-chip peripherals such as timers, communication interfaces, and analog blocks. The PIC32MX2xx family specifically uses the MIPS M4K architecture and is positioned at the lower end of Microchip's 32-bit portfolio, below the PIC32MX5/6/7 series but above the 16-bit PIC24/PIC28 families. PIC32MX2xx parts typically expose USB, I2S, PMP (parallel master port), CTMU (charge time measurement unit), and Peripheral Pin Select (PPS), giving designers flexibility in pin assignment.
Key features of the PIC32MX220F032B-V/SS include 32 KB (32K x 8) Flash, 8 KB SRAM, 21 general-purpose I/O pins (some package variants expose up to 34 I/O), a 16-channel 10-bit ADC with 1 Msps conversion rate, two I2C, two UART, two SPI, and one USB 2.0 full-speed OTG interface. A 5-channel 16-bit timer/counter block and five 16-bit general-purpose timers provide flexible PWM and capture/compare functions. The 2.3V to 3.6V supply range supports single-cell Li-ion or regulated 3.3V systems, while on-chip CTMU enables mTouch capacitive touch sensing without an external touch controller IC.
The part's technical core is the MIPS32 M4K RISC pipeline with hardware multiply/divide, single-cycle 32-bit ALU, and prefetch cache that hides Flash latency. With 32 KB Flash and 8 KB SRAM, this variant targets mid-sized embedded applications such as USB peripherals, small graphic interfaces via PMP, sensor fusion, and motor control. Code density is excellent thanks to the MIPS instruction set plus Microchip's compact 16-bit instruction mode, allowing many applications to fit easily within the 32 KB Flash budget.
Typical applications for the PIC32MX220F032B-V/SS include USB HID/CDC peripherals (mice, keyboards, custom HID devices), low-cost graphics with PMP, capacitive touch user interfaces via mTouch, sensor hubs, industrial control nodes, and small audio playback interfaces through I2S. Automotive AEC-Q100 qualification opens in-cabin HMI, body controllers, and accessory modules. The 28-SSOP package keeps the part compatible with hand-soldering and breadboarding, which is helpful in prototype and small-volume runs.
When designing with this MCU, allocate 4 Kbytes for bootloader + 28 Kbytes for application when using the USB bootloader, and ensure the 3.3V rail is clean (LDO, not switcher) because the 10-bit ADC is sensitive to ripple near the MCU supply pins. Use Microchip's MPLAB X IDE and Harmony v3 framework for pin configuration and peripheral drivers; the device is also supported by the open-source pic32prog and xc32 toolchain.

USB HID Peripheral (Mouse/Keyboard)
The PIC32MX220F032B-V/SS is a strong fit for USB HID peripherals because it integrates a USB 2.0 Full-Speed OTG controller and a 40 MHz MIPS32 M4K core capable of handling HID class drivers, debouncing, and reporting logic without external PHY. Its 32 KB Flash and 8 KB SRAM comfortably fit the USB HID stack plus scan matrix logic for a 6-8 button device, while the 21 GPIO in the 28-SSOP variant drive buttons, scroll wheels, and indicator LEDs. The 2.3V-3.6V supply is compatible with USB bus-powered 3.3V regulation via LDO. AEC-Q100 qualification enables rugged industrial mice and automotive seat-control HMI where reliability matters. A typical circuit uses direct 5V VBUS through an LDO to the MCU's VDD, the internal pull-up on D+, and pin-muxed I/O for the scan matrix.
Empfohlen
Capacitive Touch User Interface (mTouch)
The PIC32MX220F032B-V/SS is ideal for capacitive touch interfaces because it integrates the CTMU (Charge Time Measurement Unit) peripheral for mTouch scanning without an external touch controller. The 40 MHz core handles button, slider, and proximity algorithms in real time, and the 16-channel 10-bit ADC monitors voltage drops on charge cycles for reliable touch detection. With 21 GPIO in the 28-SSOP, the MCU can serve a 16-key keypad plus 5 control buttons. V-grade -40C to +105C operation supports touch panels in outdoor or industrial environments, while AEC-Q100 qualification is mandatory for automotive center stack and steering wheel controls. A typical schematic connects the CTMU pins directly to ITO pads, with the MCU powered from a clean 3.3V LDO to maximize SNR on the analog comparator.
Empfohlen
Small Graphics Display via PMP
The PIC32MX220F032B-V/SS supports PMP (Parallel Master Port) for driving small parallel TFT or STN LCDs, which is uncommon on low-cost MCUs. With 8 KB SRAM, the part can buffer a small 128x64 monochrome framebuffer (1 KB) plus font tables and still have headroom for application logic. The 40 MHz core achieves reasonable refresh rates for 1-3 inch displays, while the 28-SSOP package gives breadboard-friendly debug access during prototype. The 3.3V supply matches the I/O voltage of typical small TFT panels. A typical implementation uses PMP data lines on port pins plus a small boost driver (e.g., TPS61040) for backlight; the MCU serves as the master, refreshing the panel while leaving cycles for UI logic.
Empfohlen
Industrial Sensor Hub
The PIC32MX220F032B-V/SS fits industrial sensor hubs that aggregate multiple sensor inputs (temperature, humidity, analog) and forward them via UART, SPI, or USB. Its 16-channel 10-bit ADC supports up to 16 sensor channels, while the 32 KB Flash holds sensor-fusion and Modbus/CANopen protocol stacks. Two UART and two SPI can simultaneously drive a UART-to-RS485 transceiver and an SPI sensor like an accelerometer. AEC-Q100 V-grade temperature range supports outdoor and factory-floor installations. A typical design uses a 4-wire SPI port for an external ADC, a UART for Modbus RTU, and a USB-CDC bridge for commissioning via laptop. The 28-SSOP aids serviceability with hand-solderable pads.
Empfohlen
USB CDC Serial Bridge
The PIC32MX220F032B-V/SS is a natural choice for USB-to-UART/SPI bridge dongles because of its built-in USB OTG and two UART peripherals. The 32 KB Flash and 8 KB SRAM easily fit a USB CDC ACM class driver plus bridging logic, allowing the device to enumerate as a virtual COM port on a PC without custom drivers. Its 40 MHz MIPS core handles 921600 baud UART bridging at full USB Full-Speed (12 Mbps) throughput. The 28-SSOP package is breadboard-friendly for prototypes and small-volume products. Typical applications include debugging boards without USB, replacing FTDI cables, and adding USB connectivity to legacy RS-232 designs. Power is supplied from the USB 5V rail through an onboard 3.3V LDO.
Empfohlen
Audio Playback via I2S
The PIC32MX220F032B-V/SS supports I2S audio output for low-rate audio playback applications such as doorbells, message-on-hold units, and industrial alert speakers. Its I2S peripheral streams 16-bit stereo audio up to standard 48 kHz sample rates, and the 8 KB SRAM can buffer short audio clips (about 250 ms of 16-bit 16 kHz mono). The 32 KB Flash stores a compressed audio format (e.g., ADPCM or 8-bit WAV) that the MCU decodes in real time. AEC-Q100 qualification makes the part attractive for automotive chimes and warning sounds. A typical design connects the I2S lines to an external DAC like the PCM5101A, with the MCU providing clocks and data. The 28-SSOP keeps the BOM compact and the PCB low-cost.
Empfohlen
Automotive Body Control Module
The PIC32MX220F032B-V/SS is well suited for automotive body control modules that manage lighting, mirror actuators, and seat controllers. Its AEC-Q100 qualification and V-grade -40C to +105C temperature range satisfy in-cabin conditions. The 21 GPIO handle LED drivers, H-bridge enable signals, and CAN/ LIN-transceiver handshakes via a UART port. With 32 KB Flash and 8 KB SRAM, the part fits a typical body control state machine plus diagnostic firmware. The 28-SSOP package eases through-hole and wave-solderable assembly for high-volume automotive PCBs. A typical design couples the MCU with a LIN transceiver such as Microchip's MCP2021A, a CAN transceiver like MCP2551, and FET drivers for lamps. The MCU also runs a bootloader over UART or CAN for field firmware updates.

Designhinweise
The PIC32MX220F032B-V/SS draws up to 25 mA active at 40 MHz with all peripherals on, per Microchip datasheet DS60001168L. Use a low-noise LDO such as Microchip MCP1700 (3.3V, 250 mA) and place a 100 nF decoupling capacitor within 5 mm of each VDD pin (pins 7 and 20). Add a 10 uF bulk capacitor on the 3.3V rail to support the in-rush during Flash programming via ICSP. For USB applications, the internal 3.3V LDO derived from the 5V VBUS rail must source at least 100 mA peak; an external LDO is recommended instead of relying on the bus-power rail directly.
Estimated: at 40 MHz active with all peripherals and GPIO driving, the MCU draws approximately 20 mA at 3.3V, dissipating about 66 mW. The 28-SSOP package has a thermal resistance of approximately 80 C/W (theta_JA), resulting in a junction temperature rise of only 5C above ambient. Even at 105C ambient, the part is within its rated temperature window. No thermal management is required for normal operation, but ensure the PCB copper area is at least 100 sq mm on the SSOP ground pour to support production derating.
Place the VCAP pin 18 capacitor (4.7 uF low-ESR ceramic) within 5 mm of the pin; this is the internal 1.8V core regulator output and must be stable. For USB applications, keep the D+/D- traces to the USB connector matched in length to within 2 mm and route them with a ground reference plane to maintain 90 ohm differential impedance. The ICSP connector (PGEC1/PGED1 on pins 25-28) must remain accessible for in-circuit programming; do not place other components above or below these pads. Keep the analog input traces (AN0-AN15) short and routed away from the USB differential pair to minimize ADC noise.
Do not exceed 3.6V on any VDD pin; the part has no internal 5V tolerance on digital I/O. The PGECx/PGEDx pairs are 3.3V logic only; using a 5V PIC programmer can damage the MCU. Do not leave the VCAP pin floating or use an electrolytic capacitor on it; the internal regulator requires low-ESR ceramic. When using the CTMU for capacitive touch, the touch inputs must be guarded by a free analog input pin to suppress moisture-induced false touches. The USB D+ pull-up resistor must be 1.5 kOhm to 3.3V and not to 5V. Finally, always clear the JTAGEN bit in the configuration words if JTAG is not used, freeing the RA0/RA1/RA4/RA5 pins for GPIO.
