PIC32MX664F064L-I/PT 概要
A microcontroller (MCU) is a single-chip computer containing a processor core, program memory (Flash), working memory (RAM), and programmable I/O peripherals. The PIC32MX664 belongs to the MIPS32 M4K architecture family, which uses a 5-stage Harvard pipeline with separate instruction and data buses for higher throughput than von-Neumann designs. Within the broader taxonomy, this IC is a 32-bit MCU, sitting under the categories: microcontroller -> embedded processor -> integrated circuit -> semiconductor. The MIPS16e ISA extension reduces code size by up to 40%, useful when Flash is constrained.
Key features include 53 digital I/O pins, 16-channel 10-bit ADC at 1 Msps, two I2C, two SPI, two UART, two CAN 2.0B controllers, and a Parallel Master Port. The device operates from 2.3V to 3.6V with industrial -40C to +85C temperature range. On-chip peripherals include five 16-bit timers, five input capture, five output compare, and a real-time clock calendar. The 5-stage pipeline enables high code density and deterministic interrupt latency for real-time control.
Typical applications include industrial Ethernet gateways, USB host/device embedded products, CAN-based automotive body controllers, graphical HMI panels via PMP, and Ethernet-connected sensor nodes. The integrated MAC reduces BOM cost compared to external Ethernet controllers, while USB OTG enables device/host/dual-role operation without companion chips.
When designing with this MCU, allocate at least 4KB Flash for the bootloader and reserve one DMA channel for USB plus one for Ethernet to prevent starvation. For low-EMI designs, place the 8MHz primary oscillator crystal within 0.5 inch of the OSC1/OSC2 pins with a grounded guard ring. The 100-pin TQFP package exposes the full peripheral set at the cost of 12x12mm PCB area.

主な用途
PIC32MX664F064L-I/PT の用途: 6 件s: Industrial Ethernet Gateway, USB Host/Peripheral Embedded Device, CAN-Based Automotive Body Controller, Graphical HMI Display Controller, Ethernet-Connected Sensor Node, Industrial Motor Control with CAN.
Industrial Ethernet Gateway
The PIC32MX664F064L-I/PT is purpose-built for industrial Ethernet gateways because it integrates a 10/100 Ethernet MAC with MII/RMII and four dedicated DMA channels for packet transfer. At 80 MHz / 105 DMIPS the M4K core can run lwIP TCP/IP stack with HTTP/MQTT servers while leaving CPU headroom for application logic. The integrated MAC eliminates external Ethernet controllers, reducing BOM cost by ~$2 per board. Two CAN 2.0B controllers allow bridging CAN bus sensors to Ethernet networks for factory automation. Operating temperature -40C to +85C suits industrial enclosures, and the 2.3-3.6V supply tolerates noisy 24V-derived rails with proper regulation.
おすすめ
USB Host/Peripheral Embedded Device
USB 2.0 On-The-Go with integrated PHY makes this MCU ideal for USB host, device, or dual-role embedded products such as USB mass-storage copiers, USB-UART converters, and HID-class instruments. The dedicated DMA channels offload bulk USB transfers, sustaining 12 Mbps full-speed or 480 Mbps high-speed (when paired with ULPI PHY) without CPU saturation. The 64 KB Flash accommodates USB stack + class drivers (CDC, HID, MSD), while 32 KB SRAM handles double-buffered endpoints. Industrial temperature grade suits test instruments and field equipment operating in harsh environments without additional thermal management.
おすすめ
CAN-Based Automotive Body Controller
Dual CAN 2.0B controllers and the 16-channel 10-bit ADC at 1 Msps support automotive body controllers managing lights, door modules, and climate controls. The PIC32MX664F064L-I/PT integrates both CAN buses without external controllers, reducing PCB area and BOM. Note this part is industrial-grade (-40C to +85C); for AEC-Q100 qualified automotive environments, consider the PIC32MX664F064HT-I/PT which shares the same 100-pin TQFP. The 5-stage MIPS pipeline provides deterministic interrupt latency critical for CAN message handling at 1 Mbit/s. Operating from 2.3-3.6V tolerates automotive 12V battery transients when paired with proper LDO regulation.
おすすめ
Graphical HMI Display Controller
The Parallel Master Port (PMP) and 32 KB RAM enable direct connection to TFT LCD displays with resolutions up to 480x272 (WQVGA) using external frame buffer, or smaller QVGA displays with internal memory. The 80 MHz core provides enough throughput to render text, buttons, and simple graphics at 30+ FPS. 64 KB Flash holds the GUI framework (e.g., Microchip's MLA graphics library) plus application logic. The 100-pin TQFP exposes the full PMP data/control bus plus GPIO for touch sensing and backlight control. Two SPI channels support external Flash for asset storage, while the RTCC handles time-stamped event logging.
おすすめ
Ethernet-Connected Sensor Node
Combining the integrated Ethernet MAC with 16 ADC channels and I2C/SPI expansion, this MCU builds compact sensor aggregation nodes for building automation or environmental monitoring. The 4 dedicated DMA channels handle continuous Ethernet streaming while the CPU polls sensors and runs local control loops. Power consumption of approximately 70 mA active and 50 uA sleep supports Power-over-Ethernet (PoE) Class 1 designs. The industrial temperature grade suits outdoor enclosures, and the 32 KB SRAM accommodates lwIP + HTTP server + JSON payload buffers for REST API endpoints.
おすすめ
Industrial Motor Control with CAN
The PIC32MX664F064L-I/PT drives small BLDC or stepper motors via its 5 output compare PWM channels while communicating over CAN to a higher-level controller. The 5-stage pipeline delivers deterministic PWM timing suitable for field-oriented control (FOC) of permanent magnet motors up to approximately 1 kW. The 16-channel ADC samples phase currents at 1 Msps for closed-loop torque control. With two CAN buses, the controller can simultaneously participate in a CANopen or DeviceNet network and a proprietary service bus. The 100-pin TQFP provides ample GPIO for encoder inputs, hall sensors, and fault protection signals.

設計ノート
The PIC32MX664F064L-I/PT requires separate analog and digital supply pins. Connect VDD (pins 1, 26, 50, 75, 100) and AVDD (pin 7) each to 3.3V via an inductor or ferrite bead, with 10 uF + 0.1 uF decoupling capacitors placed within 5 mm of each pin. The internal voltage regulator requires a 10 uF bulk capacitor on VCAP pin 16 to stabilize the 1.8V core supply. Failing to separate AVDD from VDD will inject digital switching noise into ADC measurements, degrading the 10-bit ADC SNR.
Place the 8 MHz primary oscillator crystal (Y1) within 0.5 inch (12 mm) of OSC1 (pin 39) and OSC2 (pin 40) with short, symmetrical traces and a grounded guard ring. Crystal load capacitors (typically 15-33 pF) must match the crystal's specified load capacitance. The USB D+/D- differential traces require 90 ohm differential impedance and length matching within 2 mm. The Ethernet MII/RMII traces should be length-matched to within 25 mm to meet IEEE 802.3 timing margins.
Do not leave the JTAG pins TMS, TCK, TDI, TDO floating - add 10 kohm pull-ups to VDD on TMS and TCK for normal operation, or for production use disable JTAG via configuration bits and repurpose the pins as GPIO. The RTCC requires an external 32.768 kHz crystal on SOSCO/SOSCI pins 11/12 or an external clock input. Without configuring the PLL, the default FRC oscillator runs at 8 MHz - this is 10x slower than the maximum 80 MHz spec. The configuration bits must be programmed correctly before USB or Ethernet can function reliably.
コンプライアンス情報
RoHS compliant per Microchip product page. Industrial temperature grade (-40C to +85C) - not AEC-Q100 qualified. For AEC-Q100 automotive qualified versions, use PIC32MX664F064HT-I/PT (different temperature grade, same package).
