The 32 KB Flash array is organized as 32K x 8, and the 8 KB SRAM supports DMA transfers for audio and graphics data streams. The CTMU provides sub-microsecond time measurement for mTouch capacitive buttons and sliders, while the PMP enables direct connection to parallel LCD controllers without glue logic. Typical applications include portable audio players and codec interfaces, small graphics displays, USB peripheral devices, capacitive touch control panels, and industrial sensor nodes. The 50 MHz core and 83 DMIPS throughput are sufficient for real-time signal processing and user-interface tasks, while the 2.3 V to 3.6 V supply range supports both 3.3 V and battery-powered designs. When designing with this device, pay close attention to the ICSP programming pins and the analog supply filtering. The PIC32MX220F032B has more than one pair of PGECx/PGEDx pins; any pair may be used for in-circuit programming, but the clock and data pins must be used as a matched pair. All VSS and VDD pins must be connected and decoupled with 0.1 uF ceramic capacitors placed close to the package. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that are not consolidated in the manufacturer datasheet, giving engineers a single reference for selection, sourcing, and layout decisions.

It integrates 32 KB Flash and 8 KB SRAM in a 28-pin SSOP package and is qualified to the automotive AEC-Q100 standard (the "-V" temperature grade, -40C to +105C). This automotive-grade part suits industrial, medical, and consumer embedded designs that need reliable 32-bit performance in a small outline package. 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.

The 28-SOIC package offers generous I/O access in a wide-body footprint suitable for hand-soldered prototypes and industrial modules. The architecture uses a 5-stage pipeline with separate buses for Flash and RAM, allowing concurrent instruction fetch and data access. The USB module has its own PLL (96 MHz / 48 MHz) decoupled from the system PLL, ensuring jitter-tolerant USB signaling even when the system clock is reconfigured. PPS lets the user remap most digital peripherals to any available I/O pin, simplifying PCB routing for densely populated boards. Typical applications include USB HID peripherals (keyboards, mice, custom joysticks), USB-to-UART bridges, low-cost data loggers with RTCC timestamping, capacitive touch key panels using CTMU, and industrial sensor interfaces where 32-bit arithmetic is needed for linearization. The wide 28-SOIC package also makes this part well-suited for educational development boards and breadboard-friendly designs. When designing with this device, ensure that VBUS sensing is wired correctly if USB Device mode is used, and add the recommended 0.1 uF + bulk capacitor network close to the VDD/VSS pins. The PPS feature means firmware must configure pin mapping before peripheral use; the IOL1WAY fuse prevents write-after-write glitches when changing remappable pins at runtime.

PIC32MX220F032BT-I/SO - 32-bit MCU 32KB 40MHz | Microchip

The Microchip Technology PIC32MX220F032BT-I/SO is a 32-bit MIPS32 M4K PIC microcontroller running at 40 MHz, with 32 KB of Flash program memory and 8 KB of SRAM, housed in a 28-pin SOIC package (7.50 mm body width). It operates from a 2.3 V to 3.6 V supply and exposes up to 34 I/O ports for peripheral expansion. What is a PIC32MX microcontroller? The PIC32MX family is Microchip's MIPS-based 32-bit MCU line that targets low-cost, low-power embedded applications where the simplicity of the PIC ecosystem (MPLAB X IDE, Harmony framework, X32C supports) meets 32-bit performance. Within the taxonomy it sits as: PIC32MX220 -> PIC32MX1xx/2xx family -> PIC32MX series -> 32-bit MCU -> microcontroller -> semiconductor. The 'MX' class emphasizes peripheral integration (USB, I2S, ADC) at MHz-class CPU throughput suitable for consumer electronics and industrial control. Key features of the PIC32MX220F032BT-I/SO include 32 KB Flash (32 K x 8), 8 KB SRAM, a 10-bit ADC with up to 13 channels, two UART modules, two I2C modules, two SPI modules, USB 2.0 full-speed OTG, five 16-bit timers/counters, and four DMA channels. Industrial-grade temperature range of -40C to +85C suits harsh environments, while peripheral pin select (PPSS) functionality provides flexible pin-function remapping. The architecture combines a 32-bit MIPS M4K core with separate bus structure for program and data, enabling deterministic interrupt response and single-cycle multiplication. Hardware DMA offloads memory transfers for peripherals such as ADC and UART, freeing CPU cycles for application logic. Independent PLLs for CPU and USB clocks allow the USB module to maintain 48-bit USB operation while the CPU runs at its maximum 40 MHz.

The Microchip PIC32MX220F032BT-V/ML is a 32-bit MIPS32 M4K PIC microcontroller running at 40 MHz, integrating 32 KB of Flash program memory and 8 KB of SRAM in a compact 28-pin QFN (ML, 6x6 mm) package. The 'BT-V' suffix indicates the tape-and-reel packaging variant qualified for the -40C to +105C automotive/V-grade temperature range, while the 'ML' suffix denotes the QFN package. What is a PIC32MX microcontroller? The PIC32MX family is Microchip's 32-bit MIPS-based microcontroller line, sitting hierarchically within the broader PIC microcontroller family (8-bit PIC10/12/16/18 -> 16-bit PIC24/dsPIC -> 32-bit PIC32) and the wider category of embedded microcontrollers -> semiconductors. PIC32MX devices combine 32-bit RISC performance (up to 83 DMIPS) with rich peripheral integration, targeting applications from general-purpose embedded control to audio, connectivity, and graphical user interfaces. Key features of the PIC32MX220F032BT-V/ML include peripheral pin select (PPS) functionality for flexible signal routing, a parallel master port (PMP) for graphics interfaces, two I2S/SPI modules for codec and serial communication, two UART and I2C modules, an integrated charge time measurement unit (CTMU) for mTouch capacitive touch sensing, and up to four DMA channels. The 32 KB Flash and 8 KB SRAM are adequate for small- to medium-sized embedded applications. Architecturally, the PIC32MX220F032B employs a MIPS32 M4K core with a five-stage pipeline and hardware multiply/divide, achieving 1.56 DMIPS/MHz. Separate PLLs are provided for CPU and USB clocks (USB 2.0 full-speed OTG is supported on the PIC32MX220 family but not exposed on all 28-QFN pins). Multiple low-power modes (Sleep, Idle, Deep Sleep) reduce current consumption to sub-mA levels for battery-powered designs. Typical applications include consumer audio devices, low-cost graphics interfaces, USB peripherals, capacitive touch user interfaces, industrial control nodes, sensor hubs, and automotive body electronics. The combination of PPS, PMP, and 32 KB Flash makes the PIC32MX220F032BT-V/ML a versatile choice for cost-sensitive 32-bit designs. When designing with this MCU, careful attention must be paid to the 28-QFN PCB land pattern - the exposed thermal pad must be soldered to a sufficiently large copper pour for thermal dissipation and electrical ground. The CTMU peripheral requires calibration for accurate touch measurements, and PPS registers must be unlocked and configured before use.

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.

PIC32MX220F032D-V/TL

PIC32MX220F032D-V/TL - 32-bit MCU 32KB 44-VTLA | Microchip

The Microchip Technology PIC32MX220F032D-V/TL is a 32-bit RISC microcontroller built on the MIPS32 M4K core, operating at 40 MHz with 32 KB of Flash program memory in a 44-pin VTLA (6x6 mm) surface-mount package. It targets cost-sensitive embedded designs that need USB, graphics, audio, and advanced analog peripherals in a small footprint. The device draws less than 0.5 mA/MHz active and includes 8 KB SRAM, 34 I/O pins, and a Charge Time Measurement Unit (CTMU) for mTouch capacitive touch sensing. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and peripherals such as timers, communication controllers, and analog blocks. The PIC32MX2XX family belongs to the 32-bit MCU taxonomy, which sits between 8/16-bit MCUs (lower performance, simpler peripherals) and application processors (much higher frequency, often running Linux). Within the Microchip PIC32 portfolio, the MX1/MX2 sub-family uses the MIPS M4K core at 40-50 MHz and is positioned for general-purpose embedded control with USB and graphics support, while MX3/MX4/MX5/MX6/MX7 series scale up in clock speed and peripheral count. Key features of the PIC32MX220F032D include two I2S/SPI modules for codec and serial communication, Peripheral Pin Select (PPS) for flexible pin mapping, and a Parallel Master Port (PMP) for graphics interfaces. The CTMU enables mTouch capacitive buttons and sliders without external touch ICs. Operating voltage is 2.3 V to 3.6 V, and the device is rated for -40 °C to +105 °C industrial temperatures, with the -V/TL suffix specifying the VTLA package in tube packaging. Architecturally, the PIC32MX220F032D combines a 5-stage pipeline MIPS32 core with a multi-vector interrupt controller, DMA, and a 1 Msps 10-bit ADC. Code executes from internal memory with single-cycle Flash access at 40 MHz, achieving 83 DMIPS. The integrated USB 2.0 full-speed device, PMP, and CTMU eliminate many external components, reducing BOM cost. This part fits USB peripherals, small graphic HMI modules, audio codec interfaces, and capacitive touch user interfaces in industrial and consumer products. Typical deployments include USB sensors, POS terminals, and embedded control panels. When designing with this MCU, allocate the 8 KB SRAM carefully for buffer-heavy USB or audio stacks; consider the PIC32MX170/270 series for larger memory headroom without changing the 44-pin VTLA footprint.

PIC32MX220F032DT-50I/PT

PIC32MX220F032DT-50I/PT - 50MHz 32-bit MCU 32KB Flash | Microchip

The Microchip Technology PIC32MX220F032DT-50I/PT is a 32-bit MIPS32 M4K microcontroller running at 50 MHz, integrating 32 KB of Flash program memory and 8 KB of SRAM in a 44-pin TQFP (PT) package. It belongs to the PIC32MX2xx family of general-purpose MCUs aimed at cost-sensitive embedded designs that need USB, advanced analog, and graphics peripherals. A 32-bit microcontroller (MCU) is an integrated processor core with on-chip Flash, RAM, and peripherals (UART, SPI, I2C, timers, ADC, USB) used to implement embedded control logic. Within the broader semiconductor hierarchy, an MCU sits below microprocessors (which need external memory) and above simple digital logic, forming the central decision-making block of almost every modern electronic product. The PIC32MX220 line extends the 16-bit PIC24/dsPIC architecture into 32-bit territory while keeping peripheral and tool compatibility with earlier PIC microcontrollers. Key features of this part include a 50 MHz maximum CPU clock yielding 50 MIPS throughput, 32 KB Flash organized as 32K x 8, 8 KB SRAM, an integrated USB 2.0 full-speed device controller with on-chip transceiver, a 10-bit 1 Msps ADC with up to 13 channels, and a CTMU (Charge Time Measurement Unit) for capacitive touch sensing. The device also offers Peripheral Pin Select (PPS) for flexible I/O mapping, two UART, two I2C, and two SPI/I2S modules, plus a Real-Time Clock and Calendar (RTCC). Architecturally, the PIC32MX220 uses a five-stage MIPS M4K pipeline with separate instruction and data buses (Harvard variant) and a tightly-coupled prefetch cache, which simplifies C-code porting from other MIPS-based platforms while preserving the PIC peripheral ecosystem. The integrated USB PHY eliminates the external transceiver required on older PIC18/24 USB parts, reducing BOM cost and PCB area. Typical applications include USB HID peripherals (keyboards, mice, custom input devices), low-cost graphics and audio playback interfaces, capacitive touch keypads using the on-chip CTMU, sensor hubs for industrial monitoring, and general-purpose 32-bit upgrades for legacy PIC16/PIC24 designs that need more Flash or RAM. The combination of USB device, RTCC, and PPS also makes it attractive for tethered IoT edge nodes. Designers should note that this MCU requires a 2.3 V to 3.6 V supply with a 3.3 V typical rail and benefits from a 10 uF bulk + 100 nF decoupling pair within a few millimetres of the VDD pins. The internal 8 MHz fast RC oscillator can be used with PLL to reach 50 MHz, eliminating the need for an external crystal in cost-sensitive assemblies.

PIC32MX220F032DT-I/ML

PIC32MX220F032DT-I/ML - 32-bit MCU, 32KB Flash, 40MHz, 44-QFN | Microchip

The Microchip Technology PIC32MX220F032DT-I/ML is a 32-bit MIPS M4K RISC microcontroller with 32KB of Flash program memory, 8KB of SRAM, and a maximum CPU clock of 40 MHz, packaged in a 44-pin QFN (8x8 mm) with an exposed thermal pad. Operating from a 2.3 V to 3.6 V supply, the part delivers up to 50 MHz/83 DMIPS performance while drawing less than 0.5 mA/MHz active, making it suitable for low-power embedded designs. What is a 32-bit microcontroller? A 32-bit microcontroller (MCU) is an integrated circuit that combines a CPU, memory, and peripherals on a single die. Within the broader taxonomy, the PIC32MX220F032DT belongs to the microcontroller family, which sits under microcontrollers and processors and the broader semiconductor IC category. Unlike 8-bit MCUs, 32-bit cores like MIPS M4K can address more memory, execute instructions in fewer cycles, and handle richer peripherals including USB, I2S, and graphics PMP interfaces. Key features include Peripheral Pin Select (PPS) for flexible signal routing, a Parallel Master Port (PMP) for graphics interfaces, two I2S/SPI modules for codec and serial communications, two UART and I2C modules, and up to four hardware DMA channels with automatic data size detection. The Charge Time Measurement Unit (CTMU) enables mTouch capacitive touch buttons and sliders, and separate PLLs for CPU and USB clocks simplify mixed-clock designs. Architecturally, the PIC32MX220F032DT uses a Harvard cache architecture with separate 16KB instruction and data caches, a 5-stage pipeline, and a single-cycle 32x32 hardware multiply plus zero-wait-state Flash access. The I/O count of 34 pins (28 general-purpose plus dedicated peripherals), 5x 16-bit timers, 5 capture inputs, and 5 compare/PWM outputs make it a general-purpose workhorse. Industrial-grade temperature range of -40C to +105C is supported. Typical applications include low-cost USB peripherals, capacitive touch user interfaces, audio codec front-ends using I2S, low-cost graphics panels driven by PMP, sensor hubs, and battery-powered IoT nodes. The wide 2.3-3.6V operating range and low active current simplify designs running directly from a single Li-ion cell or 3.3V regulated rail. When designing with this MCU, allocate the VDD/VSS pair carefully: this 44-QFN variant requires at least two VDD pins and a thermal pad tied to ground for proper heat and EMI performance. Verify the in-circuit serial programming pins (PGECx/PGEDx) are accessible for field updates, and confirm DMA channel priorities match your real-time data flow.
