PIC32MX220F032D-I/TL - 32-bit MCU 40MHz 32KB Flash 44-VTLA | Microchip
MPN: PIC32MX220F032D-I/TL ✓ AktifPIC32MX220F032D-I/TL Ringkasan
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals. Within the broader semiconductor taxonomy, an MCU belongs to the logic IC family and is a sub-category of integrated circuits. The 32-bit class is preferred when applications require DSP-class arithmetic, USB connectivity, or graphic user interfaces - all of which the PIC32MX220 series targets at low BOM cost.
Key features include a 5-stage pipeline M4K core, hardware Multiply/Divide unit, Peripheral Pin Select (PPS) for flexible signal routing, two I2S/SPI modules for codec and serial communication, a Parallel Master Port (PMP) for graphics interfaces, a Charge Time Measurement Unit (CTMU) for mTouch capacitive touch sensing, and USB 2.0 full-speed On-The-Go. Five 16-bit general-purpose timers, five input-capture and five output-compare channels, and a 10-bit 1 Msps Analog-to-Digital Converter (ADC) round out the analog and timing peripherals.
The PIC32MX220F032D-I/TL operates from a 2.3 V to 3.6 V supply over the industrial temperature range of -40 °C to +105 °C. Its low active current and multiple power-saving modes (Idle, Sleep) suit battery-powered designs, while the USB OTG and PMP peripherals enable USB peripherals and graphic LCDs without external ASICs.
Typical applications include consumer USB peripherals (HID, CDC, audio), low-cost graphic user interfaces with PMP-connected LCD panels, capacitive touch panels with sliders and buttons using the CTMU, industrial control boards, and low-power IoT edge nodes. The wide peripheral set also makes this part a strong choice for educational platforms and rapid prototyping with the PICkit 3 / MPLAB ICD toolchain.
When designing with this part, allocate one decoupling capacitor (100 nF ceramic) per VDD pin and a bulk 10 uF near the package exposed pad. The exposed pad MUST be soldered to the ground plane for thermal and electrical reasons. Configure PPS early in firmware to remap peripherals onto available I/O pins without rewiring the PCB.

Aplikasi Umum
PIC32MX220F032D-I/TL cocok untuk 7 aplikasis: USB HID/CDC Peripheral, Capacitive Touch Panel with CTMU, Graphic LCD User Interface, Industrial Control Board, Battery-Powered IoT Edge Node, Educational Microcontroller Platform, Consumer Audio DAC with USB Streaming.
USB HID/CDC Peripheral
The PIC32MX220F032D-I/TL is well-suited for low-cost USB Human Interface Device (HID) and Communications Device Class (CDC) peripherals because it integrates a full-speed USB 2.0 OTG controller and 32 KB of Flash - enough to fit Microchip's free USB stack with HID + CDC composite descriptors. With Peripheral Pin Select (PPS), the D+/D- lines can be remapped around board layout constraints without rewiring. At 3.3 V supply and a typical 30 mA active current at 40 MHz, it fits inside a bus-powered design without external regulators. Compared to a discrete USB + microcontroller, this part saves roughly $1.50 in BOM and PCB area.

Capacitive Touch Panel with CTMU
With the on-chip Charge Time Measurement Unit (CTMU), the PIC32MX220F032D-I/TL directly drives mTouch capacitive touch buttons, sliders, and wheels - no external touch IC required. The 32 KB Flash fits the mTouch reference firmware plus the USB stack, while the 10-bit ADC and 5 input-capture channels provide ample analog front-end support. The exposed-pad VTLA package allows tight PCB placement of touch electrodes on the underside of the board. Engineers can typically implement 12-16 buttons plus a slider on a single chip, with sub-100 µA quiescent current in Sleep mode supporting battery-backed wake-on-touch designs.

Graphic LCD User Interface
The Parallel Master Port (PMP) peripheral on the PIC32MX220F032D-I/TL provides an 8-bit parallel bus that interfaces directly with low-cost graphic LCD controllers (SSD1963, RA8875, ILI9340 in parallel mode), supporting small 320x240 panels with on-chip frame buffering. The 8 KB SRAM is sufficient for monochrome text-only menus; for richer graphics the PIC32MX170F256D upgrade is recommended. At 40 MHz, the part comfortably drives a 5 Hz refresh rate with the touch + USB CDC stack running concurrently.

Industrial Control Board
The PIC32MX220F032D-I/TL's industrial temperature range (-40 °C to +105 °C) and wide peripheral set make it a strong fit for industrial PLC-style control boards, sensor hubs, and Modbus gateway nodes. Its UART, I2C, and SPI interfaces handle typical fieldbus and sensor connections; the 10-bit ADC reads 4-20 mA loopback signals with 1 Msps throughput. The 32 KB Flash fits small RTOS implementations (FreeRTOS port available), and PPS lets engineers reroute signals around noisy analog traces without re-spinning the PCB.

Battery-Powered IoT Edge Node
With less than 0.5 mA/MHz active current and sub-µA Sleep-mode current, the PIC32MX220F032D-I/TL runs for years on a coin cell when used in a duty-cycled edge-sensor role. Its 8 KB SRAM is sufficient for sensor-buffer-and-forward telemetry, and the CTMU can wake the part on a touch or capacitive-proximity event without an external interrupt controller. The exposed pad VTLA 6x6 mm package drops cleanly into compact wearables and is compatible with hand-soldering or reflow. For lower sleep power the PIC32MX1xx family offers dedicated deep-sleep modes with RTCC retention.

Educational Microcontroller Platform
The PIC32MX220F032D-I/TL pairs well with Microchip's Curiosity HPC development board and PICkit 3 / MPLAB ICD 4 in-circuit debuggers, providing an inexpensive 32-bit learning platform. Its MIPS32 M4K core exposes a 5-stage pipeline that maps cleanly to assembly-level teaching, while MPLAB X IDE and Harmony framework accelerate C/C++ experimentation. The 32 KB Flash / 8 KB SRAM combination is a sweet spot for teaching interrupt-driven firmware, USB enumeration, and PMP graphics without overwhelming beginners. Drop-in upgrade paths to PIC32MX170F256D-I/TL extend the platform as students outgrow the memory budget.

Consumer Audio DAC with USB Streaming
The two I2S/SPI modules on the PIC32MX220F032D-I/TL enable a USB-to-I2S bridge that streams audio from a host PC to an external DAC. The 32 KB Flash fits a small USB audio class 1 driver, and the 40 MHz core has sufficient bandwidth to handle 48 kHz/16-bit stereo with negligible CPU loading. PPS allows the I2S pins to be routed away from the USB DP/DM pins to simplify PCB routing. For 24-bit/96 kHz audio, the PIC32MX230F064D-I/TL provides more Flash headroom without changing the board.

Catatan Desain
Place one 100 nF X7R 0402/0603 decoupling capacitor within 3 mm of every VDD pin (pins 11, 20, 30, 43) and one 10 uF bulk tantalum or ceramic near the package. The exposed thermal pad (ePad) under the 44-VTLA MUST be soldered to a continuous ground plane - this provides the dominant heat-dissipation path and a low-impedance ground return for USB DP/DM signaling. Source: Microchip PIC32MX1XX/2XX family datasheet, section 'Decoupling'.
Configure Peripheral Pin Select (PPS) registers early in firmware before invoking any peripheral. PPS unlocks only after the IOLOCK bit is cleared, and unconfigured PPS leaves peripheral signals floating - a frequent cause of 'peripheral doesn't work' on first bring-up. Keep a 10 kohm pull-up on MCLR (pin 44) and a 1 nF cap to ground for proper reset. The USB D+/D- pair (pins 37, 38) requires a 90-ohm differential impedance and matched-length routing; deviations degrade USB compliance.
Estimated: at 40 MHz with all peripherals active and USB enabled, the part draws ~30 mA from a 3.3 V rail. Add a 10% margin for cold-start in-rush and select the regulator (e.g., MCP1700) with at least 50 mA capability. In Sleep mode current drops to <2 µA with RTCC enabled, allowing deep-sleep duty cycling for coin-cell powered designs. Source: Microchip PIC32MX1XX/2XX datasheet DC characteristics.
Route the 8-bit PMP bus (RB0-RB7, pins 21-28) as a length-matched group (delta <5 mm) to the LCD connector with a ground reference plane on an adjacent layer. Place a 22 ohm series damping resistor on each PMP signal if the bus length exceeds 50 mm. The 12 MHz USB clock internal oscillator is sufficient for full-speed USB; an external 48 MHz crystal is NOT required, reducing BOM cost.
Keep the 8 MHz primary oscillator traces (OSC1, OSC2 - pins 40, 41) within 5 mm of the MCU and shield them with a ground ring. Avoid running PWM or high-current switching traces under the crystal can. The CTMU input channels should be routed with a 1-2 mm clearance to adjacent digital signals to minimize capacitive crosstalk on touch measurements.
