PIC32MX664F064HT-V/PT Übersicht
A 32-bit microcontroller (MCU) is a microprocessor core with on-chip Flash program memory, SRAM data memory, and a rich set of peripherals (timers, ADC, communication controllers, GPIO) integrated into a single silicon die. PIC32MX devices sit in Microchip's MIPS-based MCU hierarchy: PIC32MX -> PIC32 family -> 32-bit MCU -> microcontroller -> embedded processor -> semiconductor. They fill the gap between 8/16-bit PIC MCUs and more complex ARM Cortex-M parts, offering high code density and deterministic interrupt latency.
Key features of this variant include 64 KB on-chip Flash, 32 KB SRAM, USB 2.0 full-speed On-The-Go, a 16-channel 10-bit ADC, two I2C, two SPI, two UART modules, five 16-bit timers/counters, and an integrated DMA engine with four channels. Industrial-grade -40C to +105C temperature range, JTAG/ICD debugging support, and a wide 2.3V-3.6V VDD tolerance make it a strong fit for hand-held industrial and consumer products.
The M4K core implements the MIPS32 instruction set with single-cycle multiply, hardware multiply-accumulate, and a 5-stage pipeline. The DMA engine offloads repetitive peripheral transfers (ADC->RAM, SPI->RAM, UART->RAM), freeing the CPU for application logic and yielding predictable response under heavy I/O load. The USB OTG controller handles host, device, and dual-role operation without external PHY, lowering BOM cost.
Typical applications include USB peripherals (HID, CDC, mass storage), industrial sensor hubs with USB diagnostics, motor control reference platforms, low-cost graphical HMI with external LCD, and home automation gateways. The combination of USB OTG and 64 KB Flash suits dongle-style products such as programmers, data loggers, and security tokens.
A key design consideration: the 'V' temperature grade supports -40C to +105C while 'I' grade supports -40C to +85C; verify against enclosure thermal rise before selecting V parts. Engineers migrating from earlier PIC32MX534/564/575 devices get a near-direct software path because the same MIPS M4K core, register set, and peripheral library (PLIB) are reused.

Typische Anwendungen
PIC32MX664F064HT-V/PT ist geeignet für 7 Anwendungs: USB HID Peripherals, USB Data Loggers and Sensor Hubs, Industrial Control and HMI, USB Programming and Debug Dongles, Home Automation Gateways, Low-Cost Graphical LCD/Segment Displays, Audio Processing and USB Speakers.
USB HID Peripherals
The PIC32MX664F064HT-V/PT integrates a USB 2.0 full-speed On-The-Go transceiver with on-chip pull-up/pull-down resistors, removing the need for an external PHY and saving roughly $0.50 in BOM. Its 64 KB Flash accommodates USB stacks (Microchip's MLA USB framework consumes about 12-16 KB), leaving 48 KB for HID report descriptors and application logic. The 80 MHz M4K core sustains 12 Mbps USB throughput with minimal CPU loading, and the 32 KB SRAM holds HID ring buffers plus CDC notification buffers. Use the 16-channel 10-bit ADC for analog controls (joysticks, sliders, lighting sensors). Typical designs: USB keyboards, mice, gamepads, custom HID instrumentation.

USB Data Loggers and Sensor Hubs
The 16-channel 10-bit ADC (1 MSPS) combined with 4-channel DMA offloads repetitive sampling into SRAM, freeing the M4K core to run application logic and USB enumeration. The 32 KB SRAM buffers sensor data between USB transfers, supporting sustained streaming at 100 kSPS without CPU intervention. The -40C to +105C V grade tolerates outdoor enclosures and industrial cabinets. Reference: Microchip PIC32MX USB Data Logger Demo. Compared to a discrete ADC + small MCU solution, this part consolidates sampling, buffering, and USB streaming into a single chip.
Empfohlen
Industrial Control and HMI
The PIC32MX664F064HT-V/PT's 16-channel ADC reads up to 16 analog sensors (temperature, pressure, level), while the 2x UART/SPI/I2C interfaces connect to motor drivers, LCD panels, and digital sensors. The V-grade -40C to +105C rating handles factory-floor temperatures, and the 80 MHz core runs a small RTOS plus touchscreen HMI logic at the same time. The 4-channel DMA moves display refresh data to SPI-based LCD controllers without CPU overhead. Typical: process control front ends, programmable logic controllers, low-cost HMI panels, and small motor control reference designs.
Empfohlen
USB Programming and Debug Dongles
Embedded firmware developers use the PIC32MX664F064HT-V/PT to build USB-CDC bridge dongles and JTAG/ICD debuggers. The USB OTG controller enumerates as a virtual COM port without external components, and the on-chip JTAG engine can be repurposed for off-board SPI/I2C programming of other MCUs. The 32 KB SRAM is sufficient to buffer firmware images up to 64 KB during in-system programming. The -40C to +105C rating allows the dongle to operate in heated enclosures. Typical: ICSP programmers, JTAG bridges, field firmware update tools.
Empfohlen
Home Automation Gateways
Zigbee/Z-Wave bridges and Wi-Fi co-processor hosts use the PIC32MX664F064HT-V/PT to provide a USB-CDC host interface plus UART/SPI control channels. The M4K core at 80 MHz runs a lightweight TCP/IP stack or message router between USB, RF modules, and on-board sensors. The 64 KB Flash holds protocol libraries (roughly 20-30 KB) and application glue code, while 32 KB SRAM supports packet buffers. The 16-channel ADC reads analog sensors (light, gas, moisture) in parallel with digital I/O. Typical: smart-home hubs, sensor aggregators, energy monitor bridges.
Empfohlen
Low-Cost Graphical LCD/Segment Displays
Driving a small 320x240 graphical LCD over SPI or 8-bit parallel requires sustained pixel throughput - the PIC32MX664's 4-channel DMA moves frame data to the LCD controller at 80 MHz peripheral clock with zero CPU loading. The 32 KB SRAM holds a partial frame buffer (160x120x16-bit fits in 38 KB with careful color depth selection). The 2x SPI channels allow simultaneous LCD refresh and touch controller sampling. Typical: portable medical instrument displays, point-of-sale terminals, small industrial operator panels.
Empfohlen
Audio Processing and USB Speakers
USB audio class (UAC) speakers and audio interfaces use the PIC32MX664F064HT-V/PT to bridge USB audio streams to an external DAC via I2S or SPI. The 80 MHz core decodes USB isochronous packets at 48 kHz/16-bit with 6-8% CPU load, leaving room for small DSP effects (EQ, dynamics). The DMA engine streams PCM data from USB buffer to DAC with sub-millisecond latency. The 32 KB SRAM holds roughly 170 ms of stereo 48 kHz/16-bit audio. Typical: USB DAC dongles, USB headsets, audio breakout boards.

Wichtigste Unterscheidungsmerkmale
- Integrated USB 2.0 FS OTG with on-chip transceiver (vs. PIC32MX564F128HT-V/PT)
- Higher 105C operating temperature vs 'I' grade parts (vs. PIC32MX664F064HT-I/PT)
- 16-channel 10-bit ADC vs fewer channels on lower-end parts (vs. PIC32MX534F064HT-I/MR)
Designhinweise
The PIC32MX664F064HT-V/PT operates from 2.3V to 3.6V with a core voltage of 1.8V generated internally by an on-chip LDO. Decoupling requires at minimum one 10 uF bulk capacitor near the VDD pins and one 0.1 uF ceramic per VDD/AVDD pair to suppress switching noise from USB and ADC sampling. Add a ferrite bead between digital VDD and analog AVDD if ADC accuracy below 1 LSB is required; otherwise a short trace with a single 10 ohm resistor is sufficient. Estimated: at 80 MHz core clock, typical active current is roughly 60-70 mA; idle currents drop to ~20 mA.
The 64-pin TQFP (PT) 10x10 mm package has a 0.5 mm pitch and a thermal pad that must be soldered to a copper pour of at least 1 square inch for reliable operation at 105C ambient. The USB D+/D- traces should be routed as a 90-ohm differential pair and length-matched within 2 mm; keep them away from switching nodes and oscillators. The 16 MHz crystal should be placed within 5 mm of the OSCI/OSCO pins with a guard ring tied to GND to reduce EMI susceptibility.
Do not exceed 3.6V on any digital pin; the M4K core is not 5V tolerant and a 5V signal without level shifting will permanently damage the part. Configure the JTAG/ICSP pins for alternate function only after debug is complete - leaving them as JTAG prevents the application from using those GPIOs. The USB D+ pull-up (1.5 kohm to 3.3V) must be enabled by software after enumeration; it must NOT be tied hard to VDD or USB compliance fails. Lastly, when migrating from PIC32MX534/564 to PIC32MX664, the peripheral library includes differ slightly; recompile against the latest MPLAB Harmony or legacy MLA stack.
