PIC32MX170F512LT-V/PT Visão geral
What is a PIC32MX microcontroller? PIC32MX is Microchip's general-purpose 32-bit MCU family that extends the PIC architecture into the MIPS32 M4K core era. It sits in the taxonomy MCU -> 32-bit microcontroller -> MIPS-based MCU -> embedded controller, giving PIC developers a low-risk migration path from 16-bit PIC24/dsPIC to a full 32-bit instruction set with deterministic interrupt latency, single-cycle multiply, and a rich peripheral set including USB, CAN, I2S, and a 10-bit ADC.
Key features of the PIC32MX170F512LT-V/PT include two I2S ports for audio codecs, four SPI/I2S modules, USB 2.0 full-speed device/host/OTG, CAN 2.0B, a Parallel Master Port (PMP) for graphics or external memory, Peripheral Pin Select (PPS) for flexible I/O mapping, a 10-bit 1 Msps ADC with up to 28 channels, and a Charge Time Measurement Unit (CTMU) for touch and capacitance measurement. The -V suffix denotes the VDD = 2.5V-3.3V operating point; the -T suffix indicates tape-and-reel packaging; the /PT suffix denotes the 100-pin TQFP package.
The PIC32MX170F512L family combines a 5-stage pipeline M4K core with prefetch cache, byte-addressable Flash with live update, and dual-banked SRAM to support bootloader and field firmware upgrades. Compared with ARM Cortex-M0/M0+ parts in the same price band, the M4K core delivers higher single-thread Dhrystone performance per MHz and a deterministic interrupt controller, which is critical for motor control and real-time audio.
Typical applications for the PIC32MX170F512LT-V/PT include industrial HMI panels, USB audio interfaces, CAN node gateways, low-cost graphical touch controllers, and automotive body electronics where AEC-Q100 grade parts are not required. The -V/PT variant is particularly suited to audio/graphics/touch HMI boards with external PMP-driven TFTs and USB peripherals.
Designers should note that the -V/PT variant has only the lower 2.5-3.3 V VDD range (no 5 V tolerance); a 3.3 V LDO such as MCP1700 is typically paired on the same PCB. The PPS remap feature eliminates pin muxing conflicts in dense boards and is documented in the PIC32 Family Reference Manual.

Aplicações típicas
PIC32MX170F512LT-V/PT é adequado para 6 aplicaçãos: Industrial HMI Touch Panels, USB Audio Interfaces (Headset/Dongle), CAN Node Gateway / Bridge, Low-Cost Graphical Instrument Front Panels, Automotive Aftermarket Body Modules, Smart Sensor Hubs with USB Connectivity.
Industrial HMI Touch Panels
The PIC32MX170F512LT-V/PT drives 4.3 to 7 inch TFT HMI panels with its integrated Parallel Master Port (PMP), 512 KB Flash for graphical assets and font tables, and CTMU-based touch scanning. The 50 MHz M4K core renders menus at 60 fps while the CTMU handles a 4-wire resistive touch sensor matrix without an external touch IC. Combined with USB device support for configuration downloads and CAN 2.0B for industrial bus connectivity, the -V/PT variant is a single-chip HMI controller for factory automation panels operating up to +105C ambient.
Recomendado
USB Audio Interfaces (Headset/Dongle)
The PIC32MX170F512LT-V/PT integrates a USB 2.0 Full-Speed OTG controller and two I2S ports, enabling a USB-to-I2S bridge that streams 24-bit/48 kHz audio to an external DAC. The 512 KB Flash holds the USB Audio class 1.0 stack plus custom DSP blocks, and the 64 KB SRAM is large enough for 4-frame audio buffering. The -V supply range is ideal for 3.3 V bus-powered designs that also use a 5 V tolerant GPIO for headset button inputs.
Recomendado
CAN Node Gateway / Bridge
The PIC32MX170F512LT-V/PT serves as a CAN-to-UART or CAN-to-USB gateway in industrial sensor networks and automotive aftermarket diagnostics. The integrated CAN 2.0B controller with 32 acceptance filters handles bus arbitration and message filtering, while USB OTG exposes the gateway as a virtual COM port to a host PC. The 512 KB Flash fits CANopen or J1939 stack plus custom protocol translation tables, and the 64 KB SRAM buffers CAN frames during high bus load.
Recomendado
Low-Cost Graphical Instrument Front Panels
The PIC32MX170F512LT-V/PT drives segmented or dot-matrix LCDs via PMP, manages front-panel key scanning through PPS-mapped GPIO, and stores calibration data in 64 KB SRAM with battery backup. Its 50 MHz core and 83 DMIPS performance allow real-time display refresh for oscilloscope front panels, bench multimeters, and lab power supply user interfaces. The -V/PT 2.5-3.3 V supply range is compatible with 3.3 V LCD controllers.
Recomendado
Automotive Aftermarket Body Modules
The PIC32MX170F512LT-V/PT is used in non-safety automotive aftermarket body controllers such as lighting controllers, seat heaters, and auxiliary accessory modules that require CAN bus connectivity and USB service ports but do not require AEC-Q100 qualification. The 100-pin TQFP exposes enough GPIO for driving LED matrices and reading multiple switch inputs, and the -40C to +105C industrial grade covers most cabin environments.
Recomendado
Smart Sensor Hubs with USB Connectivity
The PIC32MX170F512LT-V/PT aggregates multiple sensor inputs through its 28-channel 10-bit ADC and CTMU, processes them on the M4K core, and exposes results over USB HID or CDC. With 512 KB Flash the part fits TinyML inference stubs or calibration tables for environmental sensors, and the 64 KB SRAM holds rolling buffers for time-series data. The -V/PT grade's 2.5-3.3 V VDD range matches typical MEMS sensor supplies.

Principais diferenciais
- Highest-density 100-pin TQFP MCU in PIC32MX170 family with 512 KB Flash (vs PIC32MX170F256D-I/PT)
- PIC32MX170 USB OTG + CAN 2.0B at lower cost than PIC32MX2xx (vs PIC32MX150F256H-V/PT)
- Extended industrial -40C to +105C with 5 V-tolerant digital I/O (vs PIC32MX170F512L-I/PT)
Notas de projeto
Use a 3.3 V LDO such as the MCP1700 to supply VDD from a 5 V rail; the PIC32MX170F512LT-V/PT draws up to 65 mA active at 50 MHz plus peripheral current. Place the LDO within 25 mm of the VDD pins and add a 100 nF + 10 uF ceramic bulk capacitor pair at each VDD/VSS pair. The -V variant has only 2.5-3.3 V VDD tolerance, so a 5 V supply directly on VDD will damage the part; rely on the 5 V tolerance of the digital I/O pins only.
The 100-pin TQFP (12x12 mm) requires 0.4 mm pitch traces with 0.2 mm vias; route all signals on the top layer with the bottom layer as a continuous VSS plane for return-current continuity. Decoupling: place 100 nF X7R 0402 capacitors within 2 mm of every VDD/VSS pair and one 10 uF X5R bulk capacitor near the package. Keep the 8 MHz primary oscillator traces short (under 10 mm) and guard them with a ground ring to avoid coupling noise into the PLL.
Do not assume the Peripheral Pin Select (PPS) remap table is the same across PIC32MX1xx variants - always consult the PPS chapter of the PIC32MX1xx/2xx Family Reference Manual for the specific silicon revision. When migrating from PIC32MX170 to PIC32MX150/130, verify Flash and SRAM sizes against your linker script: the 256 KB and 16 KB SRAM parts use a different memory map and require linker updates. For USB designs, add 15 kohm pull-down resistors on D+ and D- when the part is unconfigured, per the USB 2.0 specification.
Estimated: the 100-pin TQFP has theta_JA of approximately 50 C/W on a standard JEDEC 4-layer test board, giving roughly 2 C rise per 40 mA additional active current at 50 MHz. At -40C to +105C ambient the junction stays within the 125C maximum, but at extended +125C industrial temperatures expect thermal derating. Use the spread-of-pins VSS pins as thermal vias to the bottom ground plane for at least 0.5 C/W of additional heatsinking.
Informações de conformidade
RoHS compliant and lead-free per Microchip product page. The -V/PT variant is industrial grade and is not AEC-Q100 qualified; automotive programs should specify /VAO or /PT-VAO AEC-Q100 grade variants.
