PIC32MX764F128LT-V/PF Visão geral
A 32-bit microcontroller (MCU) is an integrated circuit containing a 32-bit processor core, program memory, data memory, and on-chip peripherals. The PIC32MX family sits at the entry of Microchip's MIPS-based 32-bit portfolio, providing substantially higher throughput than 8/16-bit PIC MCUs while retaining a familiar MPLAB toolchain. M4K is a 5-stage pipeline core originally licensed from MIPS Technologies, augmented by single-cycle MAC, atomic bit manipulation, and a single-wire debug port. PIC32MX5/6/7 devices further add hardware 10/100 Ethernet MAC and full-speed USB OTG, placing them in the embedded-connectivity tier above simple GPIO controllers.
Key features include 128 KB Flash (128K × 8), 32 KB SRAM, 80 MHz core with 1.56 DMIPS/MHz throughput, USB 2.0 full-speed OTG with on-chip transceiver, 10/100 Ethernet MAC, two CAN 2.0B controllers, a 16-channel 10-bit 1 Msps ADC, and an integrated DMA controller with 8 channels. The device offers up to 85 general-purpose I/O pins, two I2C, two UART (one with IrDA/ISO7816), two SPI, and a 16-bit Parallel Master Port for off-chip memory expansion. The 100-pin TQFP package supports a wide temperature grade (-V: -40 °C to +105 °C) for industrial environments.
Typical applications include industrial control panels with Ethernet/IP connectivity, USB human-interface devices (keyboards, mass storage, vendor-class peripherals), CAN-based automotive sub-modules (non-safety-critical), point-of-sale terminals, and embedded web servers. The combination of Ethernet + USB + CAN + ample RAM lets a single PIC32MX7 device replace what previously required multiple MCUs plus an external PHY. When designing with this part, pay attention to the 3.3 V supply rail noise: the integrated PLL can be sensitive to noisy rails. Decouple VDD with at least one 0.1 µF ceramic per supply pin pair plus bulk, and follow Microchip's recommended decoupling guide in the datasheet for full-speed USB applications.

Aplicações típicas
PIC32MX764F128LT-V/PF é adequado para 6 aplicaçãos: Industrial Ethernet Gateway, USB Human Interface Device (HID), Automotive CAN Node, Point-of-Sale Terminal, Embedded Web Server, Data Acquisition / Industrial Logging.
Industrial Ethernet Gateway
The PIC32MX764F128LT-V/PF fits industrial Ethernet gateways because of its integrated 10/100 Ethernet MAC, 32 KB SRAM for buffering TCP/IP stacks like lwIP or Microchip's MLA, and -V temperature grade (-40 °C to +105 °C) for fan-less industrial enclosures. Placed as the main MCU with an external PHY (e.g., DP83848) on the RMII bus, it converts industrial UART/RS-485 traffic to Modbus TCP, EtherNet/IP, or PROFINET. The 80 MHz core (about 100 MIPS Dhrystone) leaves headroom for encryption when supporting TLS. The same chip also runs the FreeRTOS or OpenRTOS kernel with multiple socket connections concurrently.
Recomendado
USB Human Interface Device (HID)
The PIC32MX764F128LT-V/PF's integrated USB 2.0 full-speed OTG controller (with on-chip transceiver and pull-up resistors) makes it well-suited for USB keyboards, mice, vendor-class peripherals, and CDC-class serial adapters. The 80 MHz core handles HID report generation without CPU starvation, and the 32 KB SRAM comfortably buffers HID ring buffers and CDC echo buffers. The on-chip USB transceiver eliminates external components, keeping BOM cost down. For battery-powered USB peripherals, the -V grade's lower current draw and ability to suspend via USB-attached logic provides 50-100 µA idle current.
Recomendado
Automotive CAN Node
In automotive body and chassis modules, the PIC32MX764F128LT-V/PF fits because of its two CAN 2.0B controllers operating up to 1 Mbit/s, the -V temperature grade supporting -40 °C to +105 °C cabin environments, and 128 KB Flash for OSEK/VDX or AUTOSAR-style stacks. Placed as the body controller behind the vehicle's CAN bus, it reads sensor CAN frames, drives lights and actuators, and forwards diagnostic data via UDS over CAN. Note: this part is NOT AEC-Q100 qualified, so it should only be used in non-safety-critical sub-modules, not in airbags, ABS, or steering.
Recomendado
Point-of-Sale Terminal
The PIC32MX764F128LT-V/PF suits point-of-sale terminals that need Ethernet (for cloud sync), USB (for barcode scanner and printer), UART (for magnetic-stripe reader), and GPIO (for keypad and LCD) on one chip. The 32 KB SRAM buffers transaction logs and partial encrypted payloads, while the 80 MHz core runs TLS handshake with the payment gateway in under 200 ms. The 100-pin TQFP 14x14 mm package is easy to hand-prototype and rework. Many POS designs also use the Parallel Master Port (PMP) to drive a TFT color display directly without an external controller.
Recomendado
Embedded Web Server
The PIC32MX764F128LT-V/PF works well as an embedded web server for remote sensor monitoring, building automation, and SCADA subsystems. Its 32 KB SRAM fits lwIP plus a small HTTP server with dynamic CGI handlers, and the 80 MHz core handles 4-8 concurrent TCP sockets at modest throughput (around 2 Mbit/s). With the on-chip Ethernet MAC and an external PHY, the device serves HTML, JSON, and CSV data without an external RTOS or memory. The -V grade supports outdoor enclosures and rooftop installations.
Recomendado
Data Acquisition / Industrial Logging
The PIC32MX764F128LT-V/PF serves as a multi-channel data logger with its 16-channel 10-bit 1 Msps ADC and 8-channel DMA controller that streams samples to SRAM without CPU intervention. The 32 KB SRAM is large enough for short continuous captures (about 6 ms at 1 Msps full bandwidth), while the 128 KB Flash holds FAT32/SD card stacks and Modbus RTU firmware. Industrial installations benefit from the -40 °C to +105 °C operating range and the 100-pin TQFP package with robust 0.5 mm pitch pins that survive vibration. Ethernet connectivity allows remote retrieval of logged data.

Notas de projeto
Estimated: PIC32MX764F128LT-V/PF current consumption at 80 MHz with all peripherals active is approximately 65 mA at 3.3 V (per Microchip datasheet DC characteristics). The 100-pin TQFP package has multiple VDD/VSS pairs - all must be connected for proper operation; missing one creates logic errors that are very hard to debug. Use at least one 0.1 µF ceramic capacitor per VDD pin pair plus a 4.7 µF bulk capacitor near the MCU. For USB applications, add a ferrite bead on VUSB to keep digital switching noise out of the analog USB supply.
Route the 80 MHz system clock and the USB DP/DM traces as a 90 Ω differential pair, keep them short, and avoid stubs. The Ethernet RMII signals (ERXD0/1, ETXD0/1, EREFCLK, EMDC, EMDIO) should also be length-matched within about 50 mil to the external PHY. Place the 25 MHz crystal within 5 mm of the OSC1/OSC2 pins with a continuous ground plane underneath to minimize EMI. If you intend to use Ethernet, allocate a complete ground-free zone under the RMII bus; do not route power or switching signals underneath.
Do not confuse the PIC32MX764F128LT-V/PF (100-pin TQFP 14x14 mm, -V temperature grade) with the PIC32MX764F128LT-V/PT (100-pin TQFP 12x12 mm) - same silicon but different land patterns. Do not confuse -V (-40 °C to +105 °C) with -I (-40 °C to +85 °C). When designing for industrial environments above 85 °C, the -V grade is mandatory. Watch out for the boot configuration bits: MCLR must be pulled high through a 10 kΩ resistor for normal operation, and the PGECx/PGEDx pins must be accessible for in-circuit serial programming (ICSP).
Allocate separate ground returns for the analog section (ADC VREF+, VREF-) and the digital section (VSS pins) and join them at one point near the MCU. Place the ADC reference decoupling capacitor (typically 0.1 µF ceramic + 10 µF tantalum) within 5 mm of the VREF+ pin. Keep the ADC input traces away from digital switching signals; if unavoidable, route them on opposite sides of the board. For USB, follow the USB 2.0 layout guide: 90 Ω differential impedance, no vias on the DP/DM pair if possible, and a clean ground plane underneath.
