PIC32MX764F128L-I/PT 개요
A 32-bit microcontroller (MCU) is a microprocessor core with on-chip Flash, RAM, and peripherals designed for embedded control. The PIC32MX family belongs to the MIPS M4K class of microcontrollers, sitting between 8/16-bit MCUs and Cortex-M class cores in performance. Within the system hierarchy, this part falls under: microcontroller -> 32-bit MCU -> MIPS M4K MCU -> PIC32MX5/6/7 connectivity family. The part is fully supported by MPLAB Harmony integrated software framework.
Key features include 16-bit parallel master port, five 16-bit timer/counters, two I2C, two SPI, and UART interfaces. The device supports 16 channels of 10-bit ADC at up to 1 Msps, 16-bit data width PMP, and JTAG/ICSP debug interfaces. The 100-pin TQFP package provides ample GPIO (up to 85 I/O pins) for embedded connectivity designs.
Typical applications include industrial Ethernet nodes, USB peripherals and OTG devices, CAN-based automotive body controllers, embedded web servers, and multi-protocol IoT gateways. The integrated Ethernet MAC and dual CAN modules make the PIC32MX764F128L-I/PT particularly suited for industrial networking and connected embedded designs.
When designing with this device, allocate proper decoupling (0.1uF + bulk) close to each VDD/VSS pair. The Ethernet MAC requires an external PHY and MII/RMII routing, while USB OTG needs careful PCB layout for the DP/DN differential pair to meet 90 ohm impedance.

일반적인 애플리케이션
PIC32MX764F128L-I/PT 적합 용도: 6 애플리케이션s: Industrial Ethernet Sensor Nodes, USB OTG Industrial Peripherals, Automotive CAN Body Controllers, Embedded Web Server / IoT Gateway, Medical Device Connectivity Hub, Industrial Automation PLC Expansion Modules.
Industrial Ethernet Sensor Nodes
The PIC32MX764F128L-I/PT fits industrial sensor nodes that must stream process telemetry over Modbus TCP, EtherNet/IP, or proprietary UDP protocols while still handling deterministic fieldbus communication. The integrated 10/100 Ethernet MAC with MII/RMII allows direct connection to a low-cost PHY (such as Microchip's KSZ8061) for a complete industrial node, while dual CAN 2.0b modules with 1024 buffers concurrently serve CANopen or DeviceNet traffic. At 80 MHz (105 DMIPS), the M4K core runs a full TCP/IP stack with concurrent RTOS task scheduling. Per the family datasheet, the -40C to +85C industrial temperature range meets IEC 60068-2 environmental requirements for factory-floor deployment.

USB OTG Industrial Peripherals
The PIC32MX764F128L-I/PT's integrated USB 2.0 On-The-Go peripheral with PHY eliminates the external PHY chip normally required for OTG, simplifying BOM for industrial USB peripherals such as data loggers, barcode scanners, and configuration tools. The MCU's 128 KB Flash comfortably fits USB device class stacks (CDC, HID, MSD, or vendor-specific) plus a small RTOS, while the 32 KB SRAM supports USB double-buffering and concurrent command processing. Per Microchip's PIC32 USB OTG framework, the part supports host, device, and OTG dual-role modes via the integrated transceiver, reducing PCB area and BOM cost versus discrete PHY solutions.
추천
Automotive CAN Body Controllers
The PIC32MX764F128L-I/PT fits non-safety automotive body and chassis controllers that need dual CAN 2.0b channels to bridge body control modules, instrument clusters, and door controllers. Each CAN channel includes 1024 message buffers per the family datasheet, sufficient for gateway filtering without an external CAN controller. Combined with 32 KB SRAM, the part can run CANopen or J1939 stacks concurrently with vehicle body logic. The industrial -40C to +85C temperature range covers in-cabin automotive deployment; for under-hood AEC-Q100 qualified alternatives, designers should consider PIC32MX family members with Q-grade markings.

Embedded Web Server / IoT Gateway
The PIC32MX764F128L-I/PT's combination of 10/100 Ethernet MAC, dual CAN, and USB OTG in a single 80 MHz MIPS M4K core makes it a strong fit for compact IoT gateways that bridge fieldbus (CAN/Modbus) to IP networks (HTTP/MQTT/CoAP). Microchip's MLA or Harmony TCP/IP stack consumes roughly 50-70 KB Flash, leaving headroom for application logic within the 128 KB Flash. The eight dedicated DMA channels offload USB, Ethernet, and CAN transactions from the CPU, keeping the M4K core free for protocol parsing and edge processing.
추천
Medical Device Connectivity Hub
The PIC32MX764F128L-I/PT supports non-invasive medical device hubs that aggregate readings from bedside sensors (USB or CAN) and forward them to hospital networks over Ethernet. Its USB OTG supports direct connection to medical USB peripherals, while dual CAN interfaces can interface with proprietary clinical instrumentation buses. The 105 DMIPS performance and 32 KB SRAM are sufficient for signal preprocessing and packetization. Note that FDA-regulated medical applications require additional IEC 60601-1 system-level compliance that the datasheet does not address; this MCU must be qualified at the system level by the OEM.
추천
Industrial Automation PLC Expansion Modules
The PIC32MX764F128L-I/PT fits PLC expansion modules that need Ethernet connectivity to a backplane plus CAN-based field I/O. The Ethernet MAC plus dual CAN enables an expansion rack to expose field I/O both to the controller (Ethernet) and to legacy fieldbus devices (CAN). With 80 MHz, the MCU runs scan-time-aware I/O handling without dedicated co-processors. Per the family datasheet, the integrated DMA offloads repetitive block transfers from the CPU, keeping deterministic scan performance even under heavy network traffic.

설계 노트
Place 0.1uF decoupling capacitors as close as possible to every VDD/VSS pair on the PIC32MX764F128L-I/PT. Add a 10uF bulk capacitor on the main 3.3V rail near the IC. The TQFP-100 package has multiple VDD/VSS pins distributed around the die to support clean internal power; missing decoupling on any pair will inject noise into the analog sections (ADC and comparators). The PIC32MX hardware checklist recommends one 0.1uF per supply pair and at least one 10uF bulk per 100-pin package.
The Ethernet MAC requires MII or RMII traces routed to an external PHY. RMII uses fewer pins (9 vs 18) and a 50 MHz reference clock, which simplifies layout. Per Microchip's PIC32MX Ethernet hardware design guide, MII traces should be 50 ohm controlled-impedance and matched within 50 mils; RMII traces should be matched within 100 mils. Keep PHY clock trace short and shield the MII/RMII bus from switching power and high-current traces.
Do not confuse the PIC32MX764F (with USB OTG with integrated PHY) for the PIC32MX564F (USB Host/Device, no OTG) when migrating designs. The PIC32MX564F lacks the integrated USB OTG transceiver, so swapping silicon without re-validating the USB section will result in a non-functional USB port. Per the family datasheet, the silicon revision suffix in the part number distinguishes OTG-enabled from non-OTG sub-families.
At 80 MHz, the PIC32MX764F128L-I/PT dissipates roughly 100-200 mW depending on peripheral activity (Ethernet MAC and DMA add load). Per the family datasheet, the TQFP-100 12x12 mm package has theta_JA of approximately 50-60 C/W on a standard JEDEC 2s2p test board with no airflow. Estimated: for industrial environments with ambient up to +85C, ensure the PCB copper pour around the exposed pad maintains junction below +125C by providing at least 1 square inch of copper flood connected to the thermal pad through thermal vias.
