It operates up to 80 MHz from a 2.3 V to 3.6 V supply and is housed in a 64-pin 9x9 mm VQFN (MR) package with exposed thermal pad. Background: a microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, volatile data memory, and a rich set of on-chip peripherals such as timers, communication controllers, and analog blocks. The PIC32MX5xx family is a MIPS32 M4K-based line positioned at the high end of Microchip's PIC32 portfolio, adding USB and CAN connectivity for embedded networking. PIC32MX5xx belongs to the broader class of 32-bit flash microcontrollers and inherits the wider PIC32MX1xx/2xx/3xx/4xx/5xx/6xx/7xx family tree. Key features include 64 KB Flash, 16 KB SRAM, an 80 MHz core delivering 1.56 DMIPS/MHz, 4-channel DMA, full-speed USB 2.0 device/host/OTG, CAN 2.0B, five 16-bit timers, two I2C, two SPI, two UART channels, a 16-channel 10-bit ADC at 1 Msps, and four parallel 16-bit comparators. The MR (VQFN-64 9x9) package exposes a thermal pad that reduces junction-to-board thermal resistance. Architecturally, the M4K core executes a 5-stage pipeline with single-cycle multiply and hardware divide, while the peripheral bus matrix allows concurrent DMA transfers between peripherals and RAM without CPU intervention. The 16 KB SRAM is split between general-purpose RAM and dedicated Ethernet/USB/CAN buffer areas. Typical applications include USB peripherals such as HID or CDC class devices, CAN-connected industrial sensor nodes, embedded TCP/IP stacks with the Microchip MLA, low-cost graphic LCD control with the PMP peripheral, and small HMI panels combining USB touch with CAN I/O expansion. Designers should budget for the VQFN exposed-pad PCB layout (thermal vias to the inner ground plane are required for the -I industrial temperature range, -40 to +85 C) and provision a 12 MHz high-speed oscillator plus the 32 kHz low-power crystal for USB full-speed operation.

The Industrial (-I) suffix specifies an operating temperature range of -40C to +85C, while the -50 suffix confirms the 50 MHz top speed grade. The PIC32MX5XX family bridges mainstream 8/16-bit PIC designs to full 32-bit processing with Peripheral Pin Select (PPS) remapping for flexible board layouts. A 32-bit microcontroller is a programmable system-on-chip that integrates a CPU core, volatile and non-volatile memory, and a rich set of peripherals (timers, ADC, communication interfaces) on a single silicon die. The PIC32MX family is a key node in Microchip's product taxonomy: it sits above the 16-bit PIC24/dsPIC families and below the Cortex-M class SAM and PIC32MK parts.

The wide peripheral set reduces BOM count by integrating USB-PHY transceivers, CAN transceivers interface logic, and audio serial ports on-chip. When designing with the PIC32MX550F256HT-V/PT, use the V grade only if the application requires the -40C to +125C automotive window; otherwise the I grade (PIC32MX550F256H-I/PT) at -40C to +85C is more cost-effective for industrial and consumer designs. This page synthesizes distributor pricing, drop-in alternatives sourced from Microchip's PIC32MX family, and practical design notes that are not collocated in the manufacturer datasheet, offering a faster engineering decision path.

It integrates USB 2.0 Full-Speed OTG, CAN 2.0B, two I2S and four SPI modules, a Parallel Master Port (PMP) with dual read/write buffers for graphics, Peripheral Pin Select (PPS), and the Charge Time Measurement Unit (CTMU) for touch and HMI sensing. A microcontroller (MCU) is an integrated circuit that combines a CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals on a single die. Within the broader semiconductor taxonomy, an MCU belongs to the class of embedded processors, which sits under microcontrollers and then under integrated circuits (ICs). The PIC32 family uses a RISC (Reduced Instruction Set Computer) MIPS32 core and is positioned for higher-performance 32-bit embedded applications. Key features include USB 2.0 Full-Speed OTG with on-the-go host/device capability, CAN 2.0B active with DeviceNet addressing support, four I2S/SPI selectable modules, a 16-channel 10-bit ADC (1 Msps), and an operating voltage range of 2.3V to 3.6V. Industrial temperature range of -40C to +85C and the 100-pin TQFP footprint expose up to 78 GPIO-capable I/O pins, enabling connectivity-rich designs without external expanders. Architecturally, the PIC32MX5XX uses the MIPS32 M4K 32-bit core with a 5-stage pipeline and hardware multiply/divide, providing deterministic interrupt latency and predictable real-time performance. The CTMU provides constant-current source/sink capability for capacitive touch and ultrasonic measurement, and the PMP with dual buffers sustains continuous graphics frame updates without CPU intervention. Typical applications include USB peripherals and embedded hosts, CAN-connected industrial nodes, audio codec DSP front-ends, HMI panels with graphics and touch, and sensor hubs with USB-CDC virtual COM ports. The combination of USB, CAN, and PMP makes this MCU a single-chip solution for industrial/automotive HMI gateways. When designing with this device, ensure decoupling per the manufacturer datasheet (low-ESR ceramic, resonance above 20 MHz), and verify PPS remapping constraints for each peripheral. Programming requires MPLAB X IDE with XC32 compiler; ICSP and JTAG are supported.

Peripherals are routed through the Peripheral Pin Select (PPS) remap block, allowing flexible assignment of digital functions to a wide choice of physical pins. A microcontroller (MCU) is a single-chip computer containing a CPU core, volatile and non-volatile memory, and on-chip peripherals such as timers, communication controllers, and analog blocks. Within the broader semiconductor taxonomy, the PIC32MX550F256L belongs to 32-bit microcontroller -> RISC MCU -> embedded processor -> semiconductor. The MIPS M4K architecture is a Harvard-style RISC core widely used in cost-sensitive 32-bit embedded designs where deterministic interrupt latency, simple C/AVR-to-32-bit toolchain reuse, and broad peripheral integration reduce total BOM cost. Key features include 50 MHz core frequency, 83 DMIPS performance, 16-channel 10-bit ADC at 1 Msps, five 16-bit timers/counters, two comparators, two UARTs, RTCC with calendar mode, CTMU for capacitive touch, and dedicated audio data paths via I²S. On-chip debug uses PGECx/PGEDx pairs supporting both ICSP programming and real-time trace through standard MPLAB tools, eliminating external emulator hardware on most designs. The PIC32MX550F256L is fabricated on a low-leakage CMOS process and operates from 2.3 V to 5.5 V across the industrial -40 °C to +85 °C range. Internal DMA, dedicated context-switch shadow registers, and a configurable instruction cache support deterministic real-time response, while PMP and dual-buffered SPI allow direct TFT panel and serial-flash interfacing for HMI products. Typical applications include USB Audio/Class-D amplifiers, segment-TFT HMI panels, CAN-bridge industrial nodes, capacitive-touch control panels, and low-power graphics instrumentation. The combination of USB OTG, CAN, and audio interfaces makes it well suited for audio/graphics HMI products where a single MCU drives display, touch, USB, and fieldbus functions. When designing with this device, ensure all VDD/VSS pin pairs are decoupled with 100 nF + bulk capacitors placed within 5 mm of each pair. Decouple AVDD/AVSS separately for the ADC and use the internal bandgap reference with an external 10 µF+1 µF bypass network. Validate trace impedance on PMP and high-speed SPI lines to avoid display artifacts.

It integrates USB 2.0 full-speed, CAN 2.0B, two I2S audio interfaces, four SPI modules, two I2C modules, and a Parallel Master Port (PMP) with dual read/write buffers aimed at graphics and HMI applications. Two on-chip analog comparators and a 16-channel 1 MSPS 10-bit ADC round out the analog subsystem. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), working memory (SRAM), and a rich set of peripherals on one die. The PIC32MX5xx family sits in the hierarchy MIPS32 -> M4K core -> PIC32 -> 32-bit microcontroller -> embedded MCU, designed to balance deterministic real-time control with the throughput required by audio decoding, USB stacks, and small graphical displays. Key features include 256 KB Flash (256K x 8), 32 KB SRAM, Peripheral Pin Select (PPS) for flexible I/O mapping, an RTCC with calendar mode, a Charge Time Measurement Unit (CTMU) for capacitive touch sensing, and a wide operating voltage of 2.5 V to 3.6 V. Industrial temperature range is -40C to +85C, matching the I/PT suffix. The architecture combines a Harvard-style M4K core with a 5-stage pipeline and hardware multiply/divide, plus a dedicated DMA controller and a 16-channel hardware crypto-free RTCC. PPS remaps most digital peripherals to nearly any I/O pin, which simplifies PCB routing when migrating between PIC32MX5xx variants and speeds up BOM consolidation. Typical applications include USB audio peripherals, CAN-connected industrial nodes, low-cost HMI panels with PMP-driven TFT displays, capacitive touch user interfaces using CTMU, and small embedded graphics controllers. The combination of two I2S ports and USB makes the part a natural fit for USB-DAC dongles and USB-to-S/PDIF bridges. When designing with this device, allocate at least 4.7 uF bulk + 0.1 uF bypass capacitors on VDD/AVDD and provide a 32.768 kHz crystal or external reference for the RTCC. Pay attention to PPS remapping in code: each peripheral function must be unlocked in the device configuration to be assigned to a physical pin. This page combines verified distributor pricing, drop-in same-package alternatives, and practical engineering design notes not consolidated on the manufacturer datasheet, giving procurement and embedded engineers a single reference for BOM decisions.

Integrated peripherals include a USB 2.0 Full-Speed OTG controller, a CAN 2.0B module with DeviceNet addressing support, two I2S and four SPI modules for codec and serial communications, a Parallel Master Port (PMP) with dual read/write buffers for graphics interfaces, and Peripheral Pin Select (PPS) for flexible I/O mapping. The -V temperature grade targets -40C to +105C operation, suitable for industrial environments. A 32-bit microcontroller (MCU) is a single-chip processor that integrates CPU, memory (Flash/RAM), and programmable peripherals. MCUs sit at the foundation of embedded systems, sitting hierarchically under the broader category of microcontrollers, then embedded processors, then semiconductors. The PIC32MX family specifically uses the MIPS32 instruction set, which differs architecturally from ARM Cortex-M cores while offering competitive code density and deterministic interrupt latency. Key features include 50 MHz core with single-cycle multiply, hardware multiply/divide, 16-bit wide instruction path, 5-channel DMA, four 16-bit timers/captures, five UART modules, two comparators, CTMU (Charge Time Measurement Unit), RTCC, and an 8-bit Parallel Master Port. The PPS system remaps digital peripherals to most I/O pins, simplifying PCB layout. Typical applications include industrial USB device controllers, CAN-based automotive node ECUs, low-cost HMI panels with PMP-driven LCDs, audio codecs bridging via I2S, and embedded point-of-sale terminals. The integrated USB OTG plus CAN combination is rare in this price tier and is the primary differentiator versus PIC32MX4xx/2xx parts that lack USB or CAN. When designing with this device, observe the 100-pin TQFP land pattern, ensure 3.3V rail decoupling within 5 mm of every VDD/VSS pair, and reserve JTAG/PGD/PGC test access per the Microchip programming specification. For CAN bus termination, add a 120 ohm resistor at each node end.
