PIC32MX764F128L-V/PF Visão geral
A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, and a rich set of on-chip peripherals used to sense, drive, and connect embedded systems. PIC32MX devices sit in the hierarchy: 32-bit MCU -> MIPS32 M4K core microcontroller -> PIC32 family -> Microchip 32-bit portfolio -> embedded microcontroller -> semiconductor. Compared with 8-bit and 16-bit MCUs, 32-bit PIC32 parts add MPU-class MIPS performance, DMA, and high-bandwidth connectivity (Ethernet, USB-OTG) that older PIC18/PIC24 families cannot deliver.
Key features include: 80 MHz MIPS32 M4K core (1.56 DMIPS/MHz, 3.68 CoreMark/MHz), 128 KB Flash with 32 KB RAM, dedicated DMA controller (8 channels), five 16-bit timers, five IC/OC/PWM modules, two UART/I2C/SPI ports plus one USB-OTG and one Ethernet MAC, a 16-channel 10-bit 1 MSPS ADC, and a Parallel Master Port (PMP) for external bus/display expansion. JTAG and 2-wire ICSP debugging are supported. The 100-pin TQFP provides ample GPIO for mixed-signal designs.
Architecturally, the PIC32MX7 sub-family adds the integrated Ethernet MAC and USB-OTG PHY interface alongside CAN, making it the most-connected variant of the PIC32MX5/6/7 lineup. The M4K core uses a 5-stage pipeline and hardware multiply/divide; DMA offloads memory-to-peripheral transfers, freeing the CPU for application logic. The 10-bit ADC shares dedicated sampling hardware rather than being software bit-banged.
Typical applications: industrial control and HMI panels with Ethernet connectivity, USB device/host peripherals (barcode scanners, data loggers, custom USB audio), CAN-based automotive and building-automation nodes, IoT gateways bridging Ethernet to local sensors, and medical device front panels. Designers often pair the PIC32MX764F128L-V/PF with an external PHY (e.g. DP83848) for Ethernet and with the MCP2200 or MCP2551 for CAN.
Design consideration: the VDD/VSS layout for a 100-pin TQFP needs at least four dedicated ground pours and 0.1 uF + 10 uF decoupling per VDD pin pair; failing to do so causes ADC noise and USB enumeration failures. Two analog supply pins (AVDD/AVSS) must be tied to the digital rails through a ferrite bead if ADC accuracy matters.

Aplicações típicas
PIC32MX764F128L-V/PF é adequado para 7 aplicaçãos: Industrial Ethernet Gateway, USB Barcode / Data-Logger Peripheral, CAN-Based Building Automation Node, IoT Edge Device with TLS / MQTT, Medical Device Front Panel HMI, Industrial Control PLC / Motor Controller, USB Audio / MIDI Device.
Industrial Ethernet Gateway
The PIC32MX764F128L-V/PF is purpose-built for industrial Ethernet gateways because it integrates a 10/100 Mbit MAC (MII/RMII to an external PHY such as DP83848) plus USB-OTG and CAN 2.0b, all in one chip. At 80 MHz the M4K core comfortably runs an lwIP TCP/IP stack with HTTP/MQTT/Modbus-TCP servers, while the 8-channel DMA engine moves packet buffers without CPU overhead. The 100-pin TQFP exposes ample GPIO for status LEDs, RS-485 transceivers, and EEPROM for configuration storage. Engineers can move to the higher-memory PIC32MX695F512L variant if their firmware needs larger TLS buffers.
Recomendado
USB Barcode / Data-Logger Peripheral
The PIC32MX764F128L-V/PF's integrated USB 2.0 Full-Speed On-The-Go controller supports both USB host (scanner, keyboard, mass storage) and USB device modes without an external interface chip. At 80 MHz the M4K core has plenty of headroom for USB class drivers (HID, CDC, MSD, vendor) plus application logic, and 128 KB Flash accommodates composite-device stacks. The 32 KB SRAM is enough for typical 64-byte USB packets and small file-system caches. The 100-pin TQFP gives enough GPIO for LCD, keypad, and buzzer in scanner housings.
Recomendado
CAN-Based Building Automation Node
The PIC32MX764F128L-V/PF's CAN 2.0b controller paired with an MCP2551 transceiver makes it ideal for BACnet/CANopen building-automation nodes such as HVAC controllers and lighting panels. The 80 MHz M4K core runs BACnet MS/TP or CANopen stacks with cycle times well under 10 ms, while the on-chip 10-bit 1 MSPS ADC handles thermistor, CT-current, and 0-10 V dimmer inputs without external converters. The 100-pin TQFP gives designers room for keypad, character LCD via PMP, and isolated RS-485.
Recomendado
IoT Edge Device with TLS / MQTT
For IoT edge nodes bridging Ethernet to local sensors, the PIC32MX764F128L-V/PF combines an 80 MHz M4K core, 128 KB Flash and 32 KB SRAM in a 100-pin TQFP, with on-chip Ethernet MAC and USB-OTG. Microchip's MPLAB Harmony v3 framework provides TCP/IP, MQTT, and wolfSSL/TLS support - firmware can publish sensor data over MQTT-TLS with reasonable RAM budgeting. Engineers targeting secure boot can leverage the on-chip Flash with Microchip's CryptoAuthLib for ECC-curve key storage.
Recomendado
Medical Device Front Panel HMI
The PIC32MX764F128L-V/PF's 80 MHz MIPS32 M4K core drives character LCDs or small TFT displays via the on-chip Parallel Master Port (PMP), while its USB-OTG allows service technicians to perform firmware updates via USB mass-storage drag-and-drop. The 10-bit 1 MSPS ADC reads sensor analog front-ends with 0.5 LSB typical linearity. The 100-pin TQFP package supports -40C to +105C operation (V grade), covering clinical and laboratory environments. Designers should add watchdog timer and external supervisor for IEC 60730 / IEC 60601-1 compliance.
Recomendado
Industrial Control PLC / Motor Controller
The PIC32MX764F128L-V/PF suits compact PLC and motor-control front-end boards where 100-pin TQFP gives enough GPIO for 16+ optically isolated digital inputs, 8 PWM outputs, quadrature encoder inputs, and a CAN/RS-485 link to a master controller. Five 16-bit timers with Input Capture provide precise period measurement for encoder feedback; 5 OC/PWM modules drive MOSFET gate drivers via isolation. The 10-bit 1 MSPS ADC samples current shunts, DC-link voltage, and temperature sensors in real time. The "V" temperature grade covers industrial cabinets.
Recomendado
USB Audio / MIDI Device
The PIC32MX764F128L-V/PF's USB-OTG and 80 MHz processing headroom enable class-compliant USB audio 1.0 devices (speaker, microphone) and USB MIDI 1.0 controllers. The 16-bit PWM + IC/OC modules can drive an external DAC's I2S clock; the 10-bit ADC handles line-level inputs for monitoring. Many DIY synth and audio-interface designs use the PIC32MX764F128L-V/PF paired with a PCM5102A I2S DAC and a TLV320AIC3254 codec for full-duplex USB audio at 48 kHz.

Principais diferenciais
- Only 100-TQFP variant combining 10/100 Ethernet + USB-OTG + CAN (vs PIC32MX664F128L-V/PF)
- Industrial -40C to +105C "V" temperature grade on standard part (vs PIC32MX764F128L-I/PF)
- Balanced 128 KB Flash / 32 KB RAM for typical IoT firmware (vs PIC32MX695F512L-80V/PF)
Notas de projeto
The PIC32MX764F128L-V/PF requires a clean 2.3-3.6 V supply with separate analog (AVDD/AVSS) pins for the 10-bit ADC. Place a 0.1 uF X7R ceramic plus 10 uF tantalum or ceramic within 5 mm of each VDD/AVDD pin pair, with a ferrite bead (e.g. BLM18PG471SN1) between digital and analog rails to keep ADC noise below 1 LSB. Power-on ramp must be monotonic; use an MCP1700 or equivalent LDO rather than a switching regulator directly on VDD to avoid Ethernet-PHY-induced switching ripple.
The 100-pin TQFP (14x14 mm, 0.5 mm pitch) demands a 4-layer PCB minimum with continuous ground pour underneath the package to keep EMI and thermal performance within spec. Estimated: at 80 MHz full CPU load, internal power dissipation is roughly 130 mW (3.3 V * 40 mA typical); the 14x14 TQFP provides adequate thermal dissipation without a heatsink for industrial applications. Use stitch vias every 5 mm around the perimeter ground pour.
Do not assume the suffix 'V' means 5 V operation - 'V' is the Microchip industrial temperature grade (-40C to +105C), and 'I' is -40C to +85C. Maximum VDD remains 3.6 V absolute-max; exceeding this destroys the part. Also, when migrating between PIC32MX7 and PIC32MX5/6, verify the PMP (Parallel Master Port) pin mapping - some signals are remapped to different ports between sub-families. Lastly, the Ethernet MAC requires an external PHY (e.g. DP83848); there is no integrated PHY in PIC32MX devices.
The 50 MHz EBI / Parallel Master Port signals on this device should be routed with 50 ohm controlled impedance if the bus runs at >40 MHz; otherwise keep the bus under 25 MHz with short traces (<50 mm). The MII Ethernet signals between MAC and PHY must be length-matched within 25 mm to avoid skew at 100 Mbit; series 33 ohm resistors near the MAC pins reduce reflections. USB-OTG D+/D- require 90 ohm differential routing and an ESD array (e.g. USBLC6-2SC6) at the connector.
