PIC32MX220F032B-I/SS Übersicht
A PIC32MX microcontroller is a 32-bit RISC MCU built on the MIPS32 M4K core architecture, intended for embedded designs that require more performance and memory than 8-bit/16-bit PIC MCUs while retaining the PIC ecosystem (MPLAB X IDE, Harmony, XC32 compiler). Within the broader taxonomy, the PIC32MX family sits between Microchip's 16-bit dsPIC/PIC24 devices and the higher-end PIC32MZ family, targeting USB-connected, audio/graphics-capable, and mixed-signal applications. The part number suffix encodes its position: 220 indicates Flash density (32 KB) and pin count, F032B identifies the Flash size code, I denotes the industrial temperature grade, and /SS marks the 28-pin SSOP package.
Key features of this part include up to 21 available I/O pins, five 16-bit timers (one can be paired into a 32-bit timer), a 10-bit ADC with up to 13 channels and 1 MSPS conversion rate, two comparators, two UART/I2C/SPI interfaces plus a dedicated USB peripheral, and CTMU for capacitive touch. The peripheral pin select (PPS) feature allows flexible remapping of digital peripherals to any compatible I/O pin, simplifying PCB layout.
Typical applications include USB HID devices (keyboards, mice, custom peripherals), consumer audio with I2S codecs, low-cost graphical LCDs driven by PMP, mTouch capacitive buttons/sliders on appliances, and industrial sensor hubs requiring 32-bit performance at PIC ecosystem cost. The PIC32MX230/250/270/274 variants in the same family offer up to 256 KB Flash, providing headroom when more code space is needed on the same footprint.

Typische Anwendungen
PIC32MX220F032B-I/SS ist geeignet für 7 Anwendungs: USB HID Peripherals (Keyboard / Mouse / Custom HID), Consumer Audio with I2S Codec, mTouch Capacitive Touch Appliance UI, Low-Cost Graphical LCD via Parallel Master Port, Industrial Sensor Hub with USB Logging, IoT Edge Node with USB-CDC Bridge, Educational 32-bit MCU Development Platform.
USB HID Peripherals (Keyboard / Mouse / Custom HID)
The PIC32MX220F032B-I/SS is purpose-built for low-cost USB Human Interface Devices thanks to its integrated USB 2.0 Full-Speed OTG controller, 40 MHz MIPS32 M4K core, and 32 KB Flash that comfortably fits HID class descriptors plus application logic. With USB on-chip and only an external 0.1 uF VBUS bypass required, BOM cost stays under USD 1 for the MCU section in volume. Peripheral Pin Select lets designers route USB D+/D- to convenient package pins while keeping other signals flexible, and the 2.3-3.6 V rail matches USB signaling levels directly. Compared to an 8-bit PIC16 with external USB, this part eliminates the USB bridge IC and reduces PCB area by roughly 40 percent.
Empfohlen
Consumer Audio with I2S Codec
The PIC32MX220F032B-I/SS dual I2S interfaces and 32 KB Flash fit small audio streaming designs such as Bluetooth-AUX dongles, soundbars, and headphone amplifiers that need a 32-bit MCU but not a full DSP. I2S pairs naturally with codecs like the TI PCM5101A or Cirrus CS4344, and DMA moves audio samples without CPU intervention. At 40 MHz the M4K core leaves headroom for user-interface glue logic, button handling, and LED control. Operating from 3.3 V also simplifies powering from a single Li-ion cell with a small LDO.
Empfohlen
mTouch Capacitive Touch Appliance UI
The PIC32MX220F032B-I/SS integrated CTMU (Charge Time Measurement Unit) and PPS simplify the implementation of capacitive touch buttons, sliders, and proximity sensors for white goods, HVAC controls, and small kitchen appliances. The CTMU measures capacitance with sub-pF resolution using only the on-chip current source, removing the need for an external touch IC. The 32-bit MIPS core runs the mTouch sensing algorithm plus the appliance control loop, while 8 KB SRAM is sufficient for scan buffers. The industrial -40 to +105 C temperature range supports oven and refrigerator environments.
Empfohlen
Low-Cost Graphical LCD via Parallel Master Port
Driving a small QVGA TFT or monochrome graphical LCD becomes affordable with the PIC32MX220F032B-I/SS because the on-chip Parallel Master Port (PMP) provides an 8-bit parallel bus and dedicated control signals that offload data writes from the CPU. Designers can connect a 128x64 KS0108 LCD or 320x240 ILI9341 TFT directly. At 40 MHz the M4K writes pixels fast enough for full-screen updates without DMA on small panels, while DMA-driven PMP enables smooth animation on larger QVGA displays. The 28-pin SSOP keeps the MCU footprint under 10x8 mm.
Empfohlen
Industrial Sensor Hub with USB Logging
Industrial sensor hubs that aggregate thermocouples, 4-20 mA loops, and strain-gauge bridges benefit from the PIC32MX220F032B-I/SS 10-bit 1 MSPS ADC, two comparators, and USB for PC-side data logging. The 32-bit MIPS core runs oversampling averaging to push effective resolution to 12 bits while USB streams the digitized values to a host at 12 Mbps. The -40 to +105 C industrial temperature range and 2.3-3.6 V operation suit factory-floor equipment powered from 24 V through a small buck regulator. PMP and CTMU remain unused and available for system integration.
Empfohlen
IoT Edge Node with USB-CDC Bridge
Deploying small IoT edge nodes that report to a host over USB-CDC virtual COM is straightforward with the PIC32MX220F032B-I/SS because USB-Full-Speed plus 32 KB Flash hosts both the CDC class driver and the application logic. Designers can update the sensor protocol without a dedicated USB-UART bridge IC. DMA transfers keep USB endpoints responsive while the CPU services sensor I2C/SPI buses. The 28-pin SSOP enables very compact sensor pucks under 15x15 mm including the USB-C connector footprint.
Empfohlen
Educational 32-bit MCU Development Platform
Universities and makers favor the PIC32MX220F032B-I/SS as the entry point to 32-bit PIC microcontrollers because MPLAB X IDE, Harmony 3 framework, and the XC32 compiler are free, and the SSOP-28 package fits low-cost breakout boards like the PIC32MX Curiosity or chipKIT DP32. Students learn USB enumeration, I2S audio, PMP graphics, and CTMU touch sensing on a single chip, then migrate to higher-density PIC32MX230 or PIC32MX170 parts without rewriting code, since the same PIC32MX1XX/2XX register set is preserved across the family.

- Industrial temperature range and wide memory headroom options on same footprint (vs. PIC32MX170F256B-I/SS)
Designhinweise
Estimated: total supply current is roughly 0.5 mA/MHz plus peripheral currents, so at 40 MHz expect 20-25 mA core draw, plus USB suspend current limits. Place a 10 uF bulk plus 0.1 uF ceramic bypass on each VDD/VSS pair (pin 8/7 and pin 18/17), and a separate 0.1 uF on AVDD/AVSS (pin 27/28) to keep ADC readings clean. For USB bus-powered designs the total suspend current must stay below 2.5 mA per USB 2.0 spec.
Route the 48 MHz USB differential pair (D+/D- on RB9/RB8) as a 90 ohm differential with matched length within 2 mm, and keep them away from switching signals and clock traces. Place the USB VBUS capacitor within 5 mm of the VBUS pin. Both ICSP pairs (PGEC1/PGED1 on RB1/RB0 and PGEC2/PGED2 on RB7/RB6) need 4.7 kohm pull-ups to VDD for in-circuit serial programming, otherwise the debugger cannot connect reliably.
Do not skip the configuration bits (DEVCFG0/DEVCFG1/DEVCFG2/DEVCFG3) - they select PLL ratios, oscillator mode, watchdog, JTAG enable, and code protection, and an incorrect PLL setting is the most common reason a PIC32MX board appears dead. Always define the FSOSCEN bit correctly for USB clocking from the primary oscillator. Use the latest MPLAB Harmony Configurator or MCC-generated initialization code rather than hand-rolled config words, since bit ordering changed between silicon revisions B and C.
Estimated: at maximum CPU activity (40 MHz, all peripherals enabled, USB active) the part draws roughly 35 mA from 3.3 V, dissipating about 115 mW. The 28-pin SSOP thermal resistance theta_JA is approximately 100 C/W, producing a junction temperature rise of about 11.5 C above ambient at full activity, well inside the +105 C operating limit. No external heatsink is required.
The 10-bit ADC achieves datasheet 1 MSPS only with a 5 ohm or lower source impedance; add an op-amp buffer if your sensor network exceeds that. Enable the ADC dedicated RC oscillator (FRC) for acquisitions and avoid switching I/O pins during a conversion to prevent digital-coupling noise. Use the CTMU with a 1 percent or better reference resistor to maintain touch-sensor accuracy across production lots.
