PIC32MX664F064LT-I/PF Visão geral
A microcontroller (MCU) is an integrated circuit that combines a processor core, non-volatile program memory (Flash), volatile working memory (RAM), and programmable peripherals in a single chip. Within the semiconductor hierarchy, an MCU sits under microcontrollers, which themselves belong to embedded ICs and broader integrated circuits. The PIC32MX6xx family specifically targets connected applications, adding full-speed USB 2.0 device/host/OTG, 10/100 Ethernet MAC, and CAN 2.0B peripherals alongside the standard UART, SPI, I2C, ADC, and timer blocks.
Key features of the PIC32MX664F064LT-I/PF include 64KB (64K x 8) Flash program memory, 32KB (32K x 8) SRAM, four 16-bit timers, five 16-bit compare/PWM outputs, a 10-bit 1 Msps ADC with up to 16 channels, two I2C, two SPI, two UART modules, full-speed USB OTG, an integrated Ethernet MAC, and a 4-channel DMA controller. The M4K core implements the MIPS32 instruction set with single-cycle multiplication and hardware multiply-accumulate, delivering 1.56 DMIPS/MBSi at 80 MHz while consuming only a few tens of milliamps in active mode.
Typical applications include industrial Ethernet nodes, USB device controllers, web-enabled sensors, point-of-sale terminals, building automation gateways, and serial-bridge converters. The integrated Ethernet and USB OTG controllers significantly reduce BOM cost compared with external PHY and bridge IC designs, while the 100-pin TQFP exposes enough I/O for color LCD panels, keypads, and sensor arrays.
Design considerations: provide a clean low-impedance ground plane, route the 80 MHz crystal traces symmetrically with guard rings, and add 100 nF decoupling near every VDD/AVDD pin. The Ethernet MAC requires an external PHY (such as the Microchip KSZ8041) and 49.9 ohm 1% termination resistors on the differential pairs. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that supplement the manufacturer datasheet.

Aplicações típicas
PIC32MX664F064LT-I/PF é adequado para 6 aplicaçãos: Industrial Ethernet Node, USB Device/Host Controller, Building Automation Gateway, Point-of-Sale Terminal, Web-Enabled Sensor Hub, CAN-Based Industrial Control.
Industrial Ethernet Node
The PIC32MX664F064LT-I/PF is well suited to industrial Ethernet nodes thanks to its integrated 10/100 Mbit Ethernet MAC and -40 C to +85 C industrial temperature grade. In a typical design, the MCU connects to an external PHY such as the Microchip KSZ8041 via RMII, runs a TCP/IP stack from the 32 KB RAM, and exposes process data over Modbus TCP or EtherNet/IP. The 80 MHz MIPS32 M4K core delivers 1.56 DMIPS/MBSi, enough headroom to run lwIP plus an application task. Compared with designs using an external bridge IC, the integrated MAC reduces BOM cost by roughly USD 1.50 per node and shrinks PCB footprint, while the industrial temperature range matches IEC 60068-2-1/2 environmental profiles.
Recomendado
USB Device/Host Controller
The PIC32MX664F064LT-I/PF integrates a full-speed USB 2.0 OTG controller with on-chip transceiver, eliminating the need for an external ULPI or UTMI+ PHY. Designers can implement USB device classes (CDC, HID, MSD) or host stacks for USB memory sticks and HID-class peripherals, all within the 64 KB Flash and 32 KB RAM budget. The MCU's 80 MHz MIPS32 core handles USB protocol overhead while servicing real-time application tasks, and the 4-channel DMA offloads bulk transfers from the CPU. Compared with discrete USB controller solutions, the integrated approach lowers BOM cost, simplifies certification (USB-IF compliance testing), and reduces PCB area for HID input devices, data loggers, and consumer peripherals.
Recomendado
Building Automation Gateway
The PIC32MX664F064LT-I/PF's triple connectivity - Ethernet, USB, and CAN - makes it a strong fit for building automation gateways that bridge BACnet MS-TP, Modbus RTU, and IP networks. The integrated CAN 2.0B controller supports HVAC and lighting buses, while the Ethernet MAC uplinks to IP backbones; the 85 I/O pins provide sufficient headroom for keypad inputs, LCD panels, and relay drivers. Running at 80 MHz with 32 KB RAM, the device executes BACnet and Modbus stacks concurrently with web-server firmware. Compared with multi-chip gateways, the single-chip integration reduces failure surface, simplifies IEC 61508 SIL assessment, and cuts enclosure size for DIN-rail mounted controllers.
Recomendado
Point-of-Sale Terminal
The PIC32MX664F064LT-I/PF supports point-of-sale terminals through its combination of USB device (for PC tethering), Ethernet (for IP payment processing), UART/SPI (for mag-stripe and EMV readers), and GPIO (for keypad scanning). The 64 KB Flash holds TLS libraries and payment-application firmware, while the 32 KB RAM accommodates packet buffers for IP transactions. The industrial temperature grade tolerates the warm enclosures typical of retail POS hardware. Compared with ASIC-based payment processors, the PIC32MX offers software flexibility for PCI PTS POI v6 firmware updates without hardware redesign, while the 100-pin TQFP exposes the I/O count required for color displays and crypto keypads.
Recomendado
Web-Enabled Sensor Hub
The PIC32MX664F064LT-I/PF excels as a web-enabled sensor hub where its 10/100 Ethernet MAC and on-chip HTTP stack expose sensor data over REST or MQTT. The 16-channel 10-bit ADC, two I2C ports, and two SPI ports accept a wide variety of analog and digital sensors, while the 4-channel DMA offloads sample streaming to the network. At 80 MHz, the M4K core runs lwIP HTTP server with sub-100 ms response times for typical REST queries. Compared with Ethernet-equipped SBC solutions, the PIC32MX in a 100-pin TQFP delivers comparable connectivity at a fraction of the power (typical 25 mA active), making it suitable for PoE-powered Class 2 sensor installations.
Recomendado
CAN-Based Industrial Control
The PIC32MX664F064LT-I/PF integrates a CAN 2.0B controller suited to industrial control loops where CANopen or DeviceNet master nodes coordinate servo drives and remote I/O. The 5 x 16-bit timers and 5 PWM outputs provide motor-control capability up to several kHz switching frequency, while the 10-bit ADC samples current and position feedback. The 80 MHz MIPS32 core runs CANopen stack with sub-millisecond cycle times, and the 32 KB RAM holds process-image buffers for typical slave devices. Compared with multi-chip CAN solutions, the integrated CAN plus Ethernet reduces board area, BOM cost, and supply-chain risk in industrial control cabinets conforming to IEC 61131-3.

Notas de projeto
Estimated: At 80 MHz active, VDD = 3.3 V, the PIC32MX664F064LT-I/PF typically draws 25-35 mA (typical current from Microchip datasheet DC characteristics). Add 100 nF decoupling on every VDD/AVDD pin and a 4.7 uF bulk capacitor within 25 mm of the MCU. Use a ferrite bead between digital VDD and analog AVDD to reduce switching-noise coupling into the ADC. Sleep current drops below 30 uA when the Ethernet MAC is disabled; the integrated Ethernet block draws an additional 15 mA when active.
Place a 4-layer PCB with a dedicated ground plane under the MCU footprint; the 100-pin TQFP requires a 14 x 14 mm land pattern with 0.5 mm pitch. Route the 80 MHz primary oscillator traces symmetrically (length-matched within 1 mm) and surround the crystal with a grounded guard ring to suppress noise injection. Decoupling capacitors must use short, wide traces to the nearest VDD pin (less than 5 mm total loop length) to minimize high-frequency impedance per typical Microchip reference designs.
The integrated Ethernet MAC requires an external PHY connected via RMII. Use 49.9 ohm 1% termination resistors on the differential pair (TX+/TX-, RX+/RX-) routed as a length-matched, 100 ohm differential pair per the IEEE 802.3 specification. Maintain 100 ohm differential impedance over a continuous reference plane; avoid crossing ground plane splits. The full-speed USB D+/D- traces must also be 90 ohm differential, length-matched within 2 mm, and routed over USB directly without stubs.
At 80 MHz with all peripherals active, the typical power dissipation is 100 mW (3.3 V x 30 mA). For the 100-pin TQFP package with theta_JA, this is well within thermal limits in industrial temperature designs without a heatsink. Estimated junction temperature rise is approximately 5-8 C above ambient for typical 4-layer PCB layouts. For high-temperature installations (ambient above 70 C), add a copper pour on top of the package exposed pad region to lower junction-to-ambient thermal resistance.
Do not float the MCLR pin - it requires a 10 kohm pull-up to VDD per Microchip datasheet recommendation; floating MCLR prevents normal operation. The VREF+ pin must be bypassed with 100 nF + 4.7 uF when using the internal ADC reference. Configuration bits must be set correctly to enable the JTAG or ICSP pins for debug access; disabling JTAG without an alternative debug strategy pins applications.
