PIC32MX664F128LT-V/PT Descripción general
A 32-bit microcontroller (MCU) is a single-chip computer core based on a 32-bit data path, registers, and address space, integrating CPU, memory, peripherals and A/D - converters on one die. The PIC32MX series uses the MIPS M4K core, a Harvard-architecture processor widely deployed in embedded connectivity applications. Within Microchip's MCU taxonomy this MCU belongs to: 32-bit MCU -> MIPS32 -> PIC32 -> PIC32MX6xx family -> USB/Ethernet connectivity class.
Key features include 128 KB Flash program memory organized as 128K x 8, 32 KB SRAM, USB OTG full-speed (12 Mbps) with on-chip transceiver, 10/100 Mbps Ethernet MAC, sixteen 10-bit ADC channels with 1 Msps conversion rate, five 16-bit timers plus five input-capture and five output-compare modules, two I2C and two SPI/I2S ports, and two UART modules. The device operates from 2.3V to 3.6V with 5V-tolerant digital I/O and supports MPLAB Harmony, MPLAB X IDE, and XC32 toolchains.
Typical applications include USB peripherals and HID devices, Ethernet-connected embedded controllers, industrial automation nodes with USB device/host capability, point-of-sale terminals, and consumer audio/visual docks. Design considerations should include the mandatory 12 MHz primary oscillator for USB operation, layout separation of analog and digital grounds, and decoupling of the 3.3V rail close to all VDD/VSS pairs. This page synthesizes distributor pricing, drop-in same-package alternatives, and application notes not found in the standalone datasheet.

Aplicaciones típicas
PIC32MX664F128LT-V/PT es adecuado para 6 aplicacións: USB HID Peripheral Devices, Industrial Ethernet Sensor Nodes, USB CDC Virtual COM Port Devices, Point-of-Sale (POS) Terminals, Audio/Visual Docking Stations, Home Automation IoT Gateways.
USB HID Peripheral Devices
The PIC32MX664F128LT-V/PT's USB OTG Full-Speed controller with on-chip transceiver makes it ideal for USB Human Interface Devices (HID) such as keyboards, mice, game controllers, and custom input peripherals. With 128 KB Flash and 32 KB SRAM, the MCU can host the full USB HID class driver plus application code and descriptor tables without external memory. Its 80 MHz MIPS M4K core handles USB polling at 1 kHz with substantial margin for application logic. The on-chip 3.3V regulator simplifies bus-powered designs, although designers must still provide 5V VBUS handling for host/OTG modes.
Recomendado
Industrial Ethernet Sensor Nodes
The integrated 10/100 Ethernet MAC combined with 32 KB RAM and 128 KB Flash makes this PIC32MX a strong fit for industrial sensor nodes using Modbus TCP, EtherNet/IP, or MQTT-over-TCP. Designers typically pair the MCU with a LAN8720A RMII PHY, providing a complete Ethernet interface on a 2-layer board. The -40C to +105C extended temperature grade supports outdoor enclosures, factory floors, and unheated cabinets. The MCU's 16-channel 10-bit ADC at 1 Msps handles multi-sensor scanning faster than the polling interval of typical industrial control systems.
Recomendado
USB CDC Virtual COM Port Devices
USB Communication Device Class (CDC) firmware running on the PIC32MX664F128LT-V/PT presents a virtual COM port to the host PC, eliminating the need for legacy RS-232 drivers in test equipment, data loggers, and configuration tools. The USB OTG Full-Speed controller with on-chip transceiver provides 12 Mbps bandwidth, and the 32 KB SRAM comfortably handles multi-packet USB buffers plus UART-side buffering. Designers can use the MPLAB Harmony USB CDC stack to generate enumeration, line coding, and control transfer handlers with minimal hand-coding.
Recomendado
Point-of-Sale (POS) Terminals
POS terminals benefit from the PIC32MX664F128LT-V/PT's combination of USB device, USB host (for barcode scanners and printers), and Ethernet MAC for back-office connectivity. The 128 KB Flash hosts USB Host stack, USB Device stack, TCP/IP stack, and application logic simultaneously. The MCU drives a character LCD or small TFT through PMP or SPI, while the 16 ADC channels read keypad or battery monitoring signals. The extended -V temperature grade supports enclosed POS environments without active cooling.
Recomendado
Audio/Visual Docking Stations
The PIC32MX664F128LT-V/PT drives USB audio class (USB Audio 1.0) speakers, headphones, and docking stations with on-chip I2S peripherals and S/PDIF receive. Its 80 MHz core and DMA controllers move audio samples with low CPU overhead, and the 32 KB SRAM buffers several milliseconds of USB isochronous data without dropouts. Ethernet and USB host capability enables AVB-like control planes for docking stations that integrate charging, audio, and LAN connectivity in one product.
Recomendado
Home Automation IoT Gateways
Home automation IoT gateways use the PIC32MX664F128LT-V/PT to bridge Zigbee/Z-Wave/Wi-Fi subnets to Ethernet, USB storage, and cloud APIs. Ethernet MAC provides the wired backbone; USB OTG host mode backs up configuration to flash drives; the ADC reads analog sensors. The MPLAB Harmony TCP/IP stack includes MQTT, HTTP, and SNTP clients ready for cloud integration, and the 128 KB Flash accommodates TLS clients with reduced cipher suites. Industrial -V temp grade handles attic and basement installations.

Notas de diseño
PIC32MX664F128LT-V/PT operates from 2.3V to 3.6V with a typical 3.3V rail. Place a 10 uF bulk tantalum or ceramic capacitor on each VDD/VDDIO pair, plus a 0.1 uF ceramic decoupling cap within 5 mm of every VDD/VSS pin pair. The on-chip LDO (when enabled) provides core voltage but still requires decoupling on VDDIN. Estimated power loss at 80 MHz, all peripherals active, is approximately 60 mA; budget 100 mA worst-case for the 3.3V regulator.
USB operation on PIC32MX664F128LT-V/PT requires a 12 MHz primary crystal oscillator (POSC), not the 8 MHz internal Fast RC. The USB module derives 48 MHz from the PLL using POSC as reference. Using FRC for USB will fail USB-IF compliance and produce timing-violated packets. Also enable the on-chip USB transceiver physically connected to D+/D- lines with 15 kohm pull-down on D- (for full-speed) or D+ depending on speed, and never let VBUS float in device mode.
For Ethernet PHY connection (e.g., LAN8720A RMII), keep the 50 MHz RMII clock trace under 25 mm and matched within 2 mm between clock and data traces. Place the PHY close to the MCU, with separate analog and digital ground planes joined at one point under the PHY. Route the Ethernet differential pairs (when using MII with integrated PHY magnetics) with 100 ohm differential impedance and isolation from switching power and USB data lines.
Estimated: at 80 MHz with all peripherals active, the 100-pin TQFP (PT) package dissipates approximately 0.18 W; the resulting junction temperature rise is roughly 18 C above ambient using the standard 32.5 C/W theta_JA. No heatsink or copper pour is required for typical applications, but for enclosed or high-temperature installations (-V part rated to +105C), add at least 1 square inch of copper ground pour under the exposed pad region.
