It operates up to 80 MHz core / 120 MHz with 150 DMIPS throughput, supporting 2.3 V to 3.6 V supply and the V temperature grade (-40 °C to +105 °C). A 32-bit MCU is a microprocessor that executes instructions on 32-bit data paths, enabling higher computational throughput than 8- or 16-bit devices. The PIC32MX3/4 family belongs to the broader PIC32 MIPS-based microcontroller hierarchy, which sits within Microchip's MCU product tree: MCU -> 32-bit MCU -> PIC32 -> PIC32MX3/4. These devices pair high core performance with rich peripherals targeted at HMI, USB, and mixed-signal embedded designs. Key features include a USB 2.0 Full-Speed OTG controller, two I²S/SPI modules for codec connectivity, Peripheral Pin Select (PPS) for flexible signal routing, a Parallel Master Port (PMP) for graphics interfaces, and a Charge Time Measurement Unit (CTMU) for touch sensing. Analog blocks deliver two comparators, a 10-bit 1 MSPS ADC with up to 28 channels, and a Real-Time Clock/Calendar (RTCC). The USB OTG plus 2.5 V/3.3 V tolerance make this part suitable for tethered consumer and industrial peripherals. The architecture combines a 5-stage pipeline M4K core with tightly-coupled SRAM and a multi-channel DMA engine that offloads data movement between peripherals and memory. The 16 KB SRAM is partitioned to allow simultaneous USB, PMP, and ADC buffering without CPU intervention in typical HMI use cases. Typical applications include USB peripherals (HID/keyboard/mouse/CDC), audio playback devices with I²S codecs, low-cost graphical HMI panels using PMP and TFT displays, capacitive touch user interfaces using CTMU, and industrial control/automation nodes requiring CAN-equivalent robustness via UART/SPI bridging. When designing, observe USB bus-powered load limits (<100 mA before enumeration, <500 mA after), provide a stable 3.3 V rail with bulk + ceramic decoupling near VDDCORE/VDDIO pins, and respect the 0.5 mm TQFP pitch by using ENIG surface finish and 0.25 mm via stitching under the exposed die attach pad for thermal dissipation.

It integrates USB-OTG, two I2S/SPI interfaces, DMA, CTMU, and a 10-bit 1 Msps ADC, making it a balanced mix of analog, connectivity, and control peripherals for embedded designs. A 32-bit microcontroller (MCU) is a single-chip computer built around a 32-bit data path, allowing it to handle larger arithmetic operations, wider registers, and higher code density than its 8- or 16-bit predecessors. The PIC32 family, based on the MIPS M4K core, sits in Microchip's mid-range performance tier and occupies the niche between 8-bit PIC MCUs and higher-end Cortex-M devices. Within the broader taxonomy, a 32-bit MCU belongs to embedded microcontrollers -> microcontrollers -> integrated circuits -> semiconductors. Key features include 100 MHz core speed with 150 DMIPS performance, USB-OTG full-speed for device/host/OTG roles, a 10-bit 1 Msps ADC with up to 16 channels, and CTMU for capacitive touch and time measurement. The part supports 5-bit programmable slew rate on I/O and runs from 2.3 V to 3.6 V across the -40 °C to +85 °C industrial temperature range. On-chip DMA enables peripherals to move data independently of the core. The PIC32MX430 family uses a 5-stage pipelined MIPS32 M4K core, separate 16 KB instruction and 4 KB data caches, and a 12 KB auxiliary Flash block dedicated to bootloader storage. Its peripheral set mirrors the larger PIC32MX5/6/7 families but with reduced I/O count and memory, allowing drop-in scaling within the same development tools (MPLAB X, Harmony). The device supports serial communication through up to six UART, two SPI/I2S, and two I2C ports. Typical applications include USB peripherals (HID, CDC, mass storage), capacitive touch human-machine interfaces, low-cost graphical LCD control, motor control BLDC/PMSM drivers, and industrial sensor hubs. The combination of USB-OTG, DMA, and CTMU is particularly attractive for touch-enabled consumer devices that also need to communicate with a host PC. When designing with this part, allocate the auxiliary Flash region if a USB bootloader is planned, and use the CTMU's precision current source for accurate touch measurements. Decoupling must include a 0.1 µF ceramic capacitor per VDD/VDDIO pair, plus a bulk 10 µF tantalum or ceramic near the supply pins.

PIC32MX440F512H-80I/MR

PIC32MX440F512H-80I/MR - 80MHz 32-bit MCU 512KB Flash USB-OTG | Microchip

The Microchip Technology PIC32MX440F512H-80I/MR is a 32-bit MIPS M4K microcontroller operating at 80 MHz (105 DMIPS), integrating 512 KB of Flash and 32 KB of SRAM, with a dedicated USB 2.0 On-The-Go peripheral (including integrated PHY), in a 64-pin VQFN (9x9 mm) package. The core combines a 5-stage pipeline, Harvard architecture, MIPS16e compressed-instruction mode, and single-cycle hardware multiply/divide, delivering up to 40% smaller code size for application firmware. The device operates from 2.3 V to 3.6 V and exposes 53 general-purpose I/O pins alongside dedicated peripherals such as a 10-bit 1 Msps ADC, DMA, I2C, SPI, UART, and PMP. A microcontroller (MCU) is a self-contained processor that integrates CPU, memory, and programmable I/O on a single die, sitting at the lowest level of embedded compute hierarchy (CPU -> MCU -> SoC -> MPU). The PIC32MX4xx family targets general-purpose and USB-connected applications where deterministic real-time control, low BOM cost, and ready USB integration outweigh the need for higher clock rates. It belongs to the broader PIC32 family of MIPS-based MCUs and slots into the larger microcontroller semiconductor category. Key differentiating features include the integrated USB-OTG transceiver (eliminating external PHY cost), 512 KB Flash/32 KB RAM memory density at this price point, hardware DMA supporting USB transfers, and the automotive/industrial -40C to +85C operating range signalled by the -80I temperature grade. The 64-VQFN exposed-pad package provides improved thermal dissipation versus TQFP-64 variants and is suited to compact USB dongle and embedded designs. Architecturally, the part uses a 32-bit MIPS32 M4K core with 5-stage pipeline and Harvard bus, allowing concurrent instruction fetch and data access. The USB-OTG module has a dedicated DMA channel that offloads packet handling from the CPU, freeing cycles for application logic. ICSP programming via PGECx/PGEDx pins enables in-circuit debug with the MPLAB REAL ICE or PICkit 5 toolchains. Typical applications are USB peripherals, embedded audio interfaces, industrial control with USB diagnostics, USB mass-storage devices, and CAN/USB gateway hubs. It suits designs where 512 KB Flash is sufficient for USB stacks plus application code, and where a small QFN footprint matters more than a TQFP pin pitch. When designing with this part, place a 0.1 uF decoupling capacitor adjacent to every VDD/VDDUSB pin and provide a 10 uF bulk capacitor on the main rail. The exposed pad must be soldered to the ground plane for thermal relief. Programming via ICSP requires short, parallel PGECx/PGEDx traces to avoid debug failures.
