PIC32MX220F032B-V/SP 概要
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash), data memory (SRAM), and a rich set of I/O peripherals. Within the broader taxonomy, this part belongs to: microcontroller -> 32-bit MCU -> MIPS-based MCU -> PIC32 family -> PIC32MX1XX/2XX sub-family. MCUs are the highest-volume class of integrated circuit (semiconductor) and form the embedded compute layer beneath SoCs, microprocessors, and application processors.
Key differentiating specifications: 50 MHz/83 DMIPS core, 32 KB Flash, 8 KB SRAM, 21 available I/O pins, 10-bit 1.1 Msps ADC with up to 13 channels, and AEC-Q100 Grade 2 (-40C to +105C) qualification. The PIC32MX220F032B is supported by MPLAB X IDE, MPLAB Harmony, and XC32 compiler for firmware development and debugging.
Architecturally, the M4K core implements a 32-bit MIPS instruction set with single-cycle multiply, hardware divide, and a 5-stage pipeline. The 32 KB Flash and 8 KB SRAM support moderate-size embedded firmware with room for protocols like Bluetooth LE, USB device, or graphics stacks. The integrated 10-bit ADC enables sensor reading without an external converter.
Typical applications include consumer and industrial control panels, low-cost audio/graphics peripherals (I2S codec interface + PMP for TFT displays), USB/HID (devices) input controllers, IoT sensor hubs using CTMU capacitive sensing, and the simplified through-hole SPDIP (SP) footprint of this suffix version suited to hobbyist prototype/production. The datasheet's family key features also reference mTouch Capacitive touch buttons and sliders, parallel master ports for graphics interfaces, and Codec interface use cases.
When designing with this part, evaluate Flash headroom: 32 KB is tight for stacks like USB + TCP/IP, and the 21 I/O pins constrain parallel-master graphics. The -V suffix designates the -40C to +105C industrial operating range; the bare/SO/SS package variants are industrial -40C to +85C only. The 28-pin SPDIP (SP) form factor is the only surface-mount/out-of-socket variant in the family; through-hole designs must use the SP/SP footprint.
This page synthesizes current distributor pricing, drop-in alternatives within the same SPDIP-28 footprint, and practical design notes not collected in a single datasheet reference. Compared to the manufacturer datasheet alone, the engineer gains pricing context, alternative parametric comparison, and CTMU/USB design guidance.

主な用途
PIC32MX220F032B-V/SP の用途: 6 件s: USB HID Device Controller, Audio Codec Interface Board, mTouch Capacitive Touch Interface, Industrial Sensor Hub, Graphics TFT Display Controller, Hobbyist / Educational Development Platform.
USB HID Device Controller
The PIC32MX220F032B-V/SP fits USB HID device designs through its integrated USB 2.0 full-speed peripheral, 50 MHz/83 DMIPS M4K core, and 8 KB data RAM for endpoint buffering. With 32 KB Flash, the MCU comfortably hosts HID class firmware (keyboard, mouse, gamepad, custom HID) plus a USB stack with room for tuning codes. The 21 I/O pins scan matrix key inputs or drive LEDs, while the 2.3V to 3.6V rail matches USB bus-powered designs. Placed as the sole MCU on the board with a USB upstream port, 12 MHz crystal, and voltage regulator; this beats a discrete USB controller + 8-bit MCU architecture by integrating the function and reducing BOM cost.
おすすめ
Audio Codec Interface Board
The PIC32MX220F032B-V/SP suits low-cost audio designs thanks to the two I2S/SPI modules designed for audio data transfer, the PMP for TFT/LCD graphics, and the 50 MHz core capable of basic audio processing (sample rate conversion, simple effects). With 32 KB Flash, the MCU runs lightweight audio firmware including I2S TX/RX drivers and a basic DSP pipeline. The 10-bit ADC enables analog input monitoring (VU meters, peak detection) while 21 I/O pins drive status LEDs and button inputs. Placed between an I2S codec (e.g., AIC23B) and a TFT display with the PMP; this integrated approach replaces a separate audio DSP plus MCU architecture with a single chip solution.
おすすめ
mTouch Capacitive Touch Interface
The PIC32MX220F032B-V/SP fits capacitive touch designs through its integrated CTMU (Charge Time Measurement Unit) for mTouch capacitive sensing, the 10-bit ADC for touch measurement, and 21 I/O pins configurable as touch channels. With 32 KB Flash and 8 KB SRAM, the MCU scans 8-12 touch buttons or a small slider, runs the capacitive sensing algorithm, and outputs via I2C/SPI/UART. The -40C to +105C industrial range suits outdoor and automotive touch interfaces. Placed on the touch PCB with a guard ring, charge resistors, and the CTMU pin matrix; the integrated CTMU eliminates the external touch sensing ASIC required by non-CTMU MCUs.
おすすめ
Industrial Sensor Hub
The PIC32MX220F032B-V/SP fits industrial sensor hub designs through its 13-channel 10-bit ADC, multiple UART/SPI/I2C peripherals, 50 MHz core for sensor fusion, and 32 KB Flash for protocol stacks. With 8 KB data RAM, the MCU aggregates data from temperature, pressure, and flow sensors via I2C/SPI and forwards aggregated data over UART or CAN. The -40C to +105C industrial temperature range handles factory floor conditions. Placed on the sensor hub PCB with RS-485 transceivers, sensor I/O, and a 3.3V regulator; this replaces PLC + external ADC + MCU designs with a single-chip integrated solution.
おすすめ
Graphics TFT Display Controller
The PIC32MX220F032B-V/SP drives small TFT displays through its Parallel Master Port (PMP) for graphics interfaces, the 21 I/O pins for display data/control, and the 50 MHz core sufficient for 320x240 QVGA refresh at low frame rates. With 32 KB Flash, the MCU stores a basic graphics library plus display-specific firmware; 8 KB SRAM handles small frame buffers for partial updates. The two SPI/I2S ports enable display SPI-mode or data-mode read-back. Placed between the host MCU and the TFT display with the PMP data/control lines; the integrated PMP eliminates the external graphics controller required by MCUs lacking parallel master capability.
おすすめ
Hobbyist / Educational Development Platform
The PIC32MX220F032B-V/SP fits educational and hobbyist designs through its SPDIP-28 through-hole package (easy breadboarding, no soldering iron required for socketed use), the M4K core at 50 MHz with 83 DMIPS, and MPLAB X IDE support with XC32 compiler. With 32 KB Flash and 8 KB SRAM, students can experiment with USB, I2S audio, PMP graphics, and CTMU capacitive touch using real-world examples. The -40C to +105C industrial range means student projects survive classroom conditions. Placed on a breadboard or development board with a 3.3V regulator, crystal, and programming header; the through-hole SPDIP-28 form factor eliminates SMT soldering challenges for beginners.

設計ノート
The PIC32MX220F032B-V/SP operates from 2.3V to 3.6V and consumes under 0.5 mA/MHz at full core speed (per datasheet). For USB applications, the internal USB PHY requires a stable 3.3V rail; place a 100 nF decoupling capacitor close to each VDD pin and a 10 uF bulk capacitor near the regulator. Use a low-dropout (LDO) regulator such as MCP1700 for USB-powered designs to minimize dropout at 3.3V output. The second VDD/VSS pair (pins 6/7 and 19/20) MUST both be connected for proper operation; floating a VDD or VSS pin causes erratic behavior or permanent damage.
At 50 MHz full-speed operation with all peripherals enabled, typical core current draw is 20-25 mA (estimated at 0.5 mA/MHz). Power dissipation in the SPDIP-28 package is approximately 75 mW at 3.3V and full speed (Estimated: 3.3V x 25 mA x 0.9 derating factor). The SPDIP-28 package has thermal resistance of approximately 70 C/W junction-to-ambient, well within the -40C to +105C industrial operating range for typical applications. For continuous high-throughput designs (USB streaming, audio DSP), verify junction temperature by measuring the package at full load and worst-case ambient.
For 50 MHz operation, place the 12 MHz primary oscillator crystal or resonator within 0.5 inches of the OSCI/OSCO pads to minimize parasitic capacitance. Use a ground guard trace around the crystal traces to reduce EMI pickup. The ICSP programming pins (RB6/RB7, RB0/RB1) need a 4.7 kohm pull-up to VDD to prevent spurious entry into debug mode during reset. For SPDIP-28 layouts, route VDD and VSS traces as wide as practical (minimum 0.5 mm) to handle current transients; use a ground plane on the bottom layer for return paths.
Common pitfalls with the PIC32MX220F032B-V/SP: (1) Floating the second VDD/VSS pair (pins 6/7 and 19/20) - both MUST be connected; (2) Forgetting the 10 uF bulk capacitor on VDD - causes brown-out resets under USB load; (3) Configuring PPS (Peripheral Pin Select) without unlocking the IOLOCK bit in OSCCON - peripheral functions appear dead; (4) Using a 16 MHz instead of 12 MHz crystal without reconfiguring the PLL - USB timing fails. Refer to Microchip application note AN1307 for PPS configuration details and the PIC32MX1XX/2XX family datasheet (DS60001168L) for clock tree configuration.
