PIC32MX664F128L-V/PT Présentation
A microcontroller (MCU) is a single-chip computer containing a processor core, program memory (Flash), data memory (SRAM), and integrated peripherals such as timers, ADC, communication controllers, and GPIO. The PIC32MX family sits in the PIC32 -> 32-bit MCU -> microcontroller -> embedded processor -> semiconductor hierarchy and is widely used where higher computational performance is needed than 8-bit or 16-bit MCUs can deliver.
Key features of the PIC32MX664F128L-V/PT include 128 KB Flash (128K x 8), 32 KB SRAM, an integrated 10/100 Ethernet MAC, USB OTG, CAN, DMA, a 10-bit ADC, and 83 programmable I/O lines. The device supports up to 80 MHz operation and provides ample connectivity peripherals, suitable for embedded networking and USB device/host/OTG applications.
The architecture is a Harvard-style MIPS32 M4K core with 5-stage pipeline, separate instruction and data buses, and tightly-coupled peripherals. The USB OTG controller, Ethernet MAC, and CAN module are all integrated on-chip, eliminating the need for external bridge devices. The DMA engine offloads data movement from the CPU, freeing it for application tasks.
Typical applications include industrial Ethernet gateways, USB-to-UART bridges, embedded web servers, industrial control with CAN connectivity, and POS terminals. The wide peripheral set and Ethernet/USB/CAN integration make it ideal for connected embedded devices requiring both real-time and networked operation.
When designing with this device, ensure that the VDDCORE pin is bypassed correctly with the recommended capacitor network, and that the 80 MHz maximum frequency matches the chosen crystal and PLL configuration. Migrating between PIC32MX5/6/7 family parts is straightforward because they share the same peripheral library, MPLAB Harmony framework, and pin-compatible packages.

Applications typiques
PIC32MX664F128L-V/PT convient pour 6 applications: Industrial Ethernet Gateway, USB OTG Device / Host Controller, Embedded Web Server / IoT Edge Node, CAN Bus Industrial Control Module, POS Terminal / Payment Device, Data Acquisition / Test & Measurement.
Industrial Ethernet Gateway
The PIC32MX664F128L-V/PT's integrated 10/100 Ethernet MAC with DMA offload makes it well-suited for industrial Ethernet gateway designs that bridge fieldbus networks to enterprise systems. With 80 MHz MIPS32 M4K core delivering 105 DMIPS, the MCU can sustain TCP/IP stack and protocol conversion workloads alongside control loops. The 32 KB SRAM supports lwIP or Microchip's TCP/IP Lite stack with concurrent connections. The wide -40 C to +105 C V-temp grade matches industrial cabinet thermal requirements. Engineers typically pair this MCU with an external PHY such as the LAN8720A and run MicrOS or RTOS via MPLAB Harmony. The integrated USB OTG also provides a maintenance port for field updates.
Recommandé
USB OTG Device / Host Controller
The PIC32MX664F128L-V/PT integrates a USB OTG full-speed controller, enabling designs such as USB-to-UART bridges, USB mass-storage devices, and USB host controllers for HID or CDC peripherals. The 80 MHz core provides the throughput needed for USB CDC at 12 Mbps, while the 32 KB SRAM accommodates buffer descriptors and application payloads. The integrated DMA engine moves USB packet data with minimal CPU intervention, freeing cycles for protocol handling. Designers typically use Microchip's USB stack within MPLAB Harmony, which includes class drivers for CDC, MSD, and HID. The 100-TQFP package exposes all USB D+/D- pins with proper ESD protection.
Recommandé
Embedded Web Server / IoT Edge Node
The PIC32MX664F128L-V/PT runs a HTTP/HTTPS web server for remote monitoring and control, leveraging its 128 KB Flash for embedded web pages and 32 KB SRAM for socket buffers. The MIPS32 M4K core delivers deterministic performance at 80 MHz for parsing requests and serving dynamic content. The integrated Ethernet MAC eliminates external bridge ICs, simplifying the BOM. Designers use Microchip's TCP/IP stack with HTTP server module within MPLAB Harmony. The 83 programmable I/O lines support multiple sensor inputs and control outputs typical of edge-node applications. The wide operating range suits outdoor or industrial cabinet deployments.
Recommandé
CAN Bus Industrial Control Module
The PIC32MX664F128L-V/PT's integrated CAN controller and 80 MHz core make it suitable for CAN-based industrial control modules such as motor controllers, sensor hubs, and automation cells. The 128 KB Flash stores CANopen or DeviceNet protocol stacks, while the 32 KB SRAM handles PDO/SDO buffers. The wide -40 C to +105 C V-temp grade meets industrial ambient requirements, and the 100-TQFP package gives plenty of GPIO for encoder feedback, PWM outputs, and digital I/O. Microchip's MPLAB Harmony CAN driver simplifies protocol implementation. The DMA engine offloads CAN message storage to/from RAM.
Recommandé
POS Terminal / Payment Device
The PIC32MX664F128L-V/PT powers point-of-sale terminal controllers that integrate Ethernet connectivity, USB peripherals (keypad, printer, card reader), and CAN or serial interfaces for back-office integration. With 128 KB Flash and 32 KB SRAM, the MCU handles transaction state machines, security libraries, and display rendering. The 10-bit ADC supports battery monitoring on portable terminals, while PWM channels drive audio transducers for transaction-complete beeps. The USB OTG controller supports external card readers or printers, and Ethernet provides IP-based payment authorization. The 100-TQFP with 83 I/O pins supports multiple peripherals in parallel.
Recommandé
Data Acquisition / Test & Measurement
The PIC32MX664F128L-V/PT's 10-bit ADC, DMA engine, and 80 MHz core make it ideal for low-speed data acquisition systems such as environmental loggers, bench multimeters, and test fixtures. The ADC samples multiple channels while DMA moves conversion results to RAM in the background, leaving CPU cycles for averaging, calibration, and USB/Ethernet streaming. The 32 KB SRAM holds ample sample buffers for streaming over USB or Ethernet at sustained speeds. The 83 GPIO lines provide ample digital I/O for status LEDs, keypads, and trigger inputs. The wide V-temp grade ensures stable measurements in varied environments.

Principaux différenciateurs
- Integrated Ethernet MAC + USB OTG + CAN at 80 MHz in 100-TQFP (vs PIC32MX320F128L-80V/PT)
- 128 KB Flash with same peripheral integration (vs PIC32MX664F064L-V/PT)
- V-temp grade -40 C to +105 C (vs PIC32MX664F128L-I/PT)
Notes de conception
The PIC32MX664F128L-V/PT requires two power rails: VDD at 2.3 V to 3.6 V for I/O and AVDD at the same range for analog. The on-chip voltage regulator generates VDDCORE at 1.8 V from VDD via the ENVREG pin. Place a 10 uF bulk capacitor on VDDCORE and 0.1 uF decoupling on each VDD/VSS pair as close to the pins as possible. The total decoupling must adhere to the manufacturer's reference design to avoid core instability at 80 MHz.
The 100-pin TQFP (12x12 mm) has 0.5 mm pitch and is suitable for 4-layer PCBs with continuous power planes. Use a continuous ground plane directly under the package to provide a low-impedance return path for the high-speed digital signals. Route the USB D+/D- pair as a 90 ohm differential with no stubs, and keep the Ethernet RX/TX pairs at 100 ohm differential. Keep oscillator traces short and surrounded by ground pour to avoid noise coupling.
Common pitfalls include: (1) floating MCLR pin - always tie to VDD via a 10 kohm pull-up for normal operation, with a capacitor to ground for ICSP; (2) incorrect JTAG/ICSP wiring - PGED1/PGEC1/PGED2/PGEC2 must be reserved for debug and not used as GPIO; (3) bootloader mode - RB0/RB1/RB3 control boot source, do not load with strong pull-up/down during reset; (5) configure the oscillator wait states per FOSC in the system clock setup.
