PIC32MX170F512L-V/PF Overview
A 32-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and programmable peripherals. The PIC32MX1XX/2XX/5XX family targets cost-sensitive HMI, audio/graphics, USB-device, and CAN-connected embedded designs. PIC32MX parts sit within Microchip's product hierarchy of MCU -> 32-bit MCU -> MIPS M4K MCU -> PIC32MX value family -> mixed-signal integrated circuit, and are supported by the MPLAB X IDE ecosystem including MPLAB Harmony and the XC32 compiler.
Key features of the PIC32MX170F512L include four SPI/I2S modules for codec and serial communications, a Parallel Master Port (PMP) with dual buffers for graphics interfaces, Peripheral Pin Select (PPS) for flexible signal routing, mTouch capacitive touch sensing, a 10-bit 1 Msps ADC with up to 48 channels, USB 2.0 full-speed device, and a CTMU (Charge Time Measurement Unit) for touch and time-of-flight measurements. The device integrates 5 16-bit timers/counters and a real-time clock/calendar with hardware CRC.
Architecturally the part uses a single-issue MIPS32 M4K core with hardware multiply/divide, 5-stage pipeline, and a 32-bit instruction path. The 512KB Flash is organized for in-circuit programming via 2-wire ICSP, and 64KB SRAM is supported by a 16-entry write buffer for sustained DMA bandwidth. JTAG debugging is available via PGECx/PGEDx pairs.
Typical applications include USB audio peripherals, HMI panels with capacitive touch, CAN-based industrial nodes, low-cost graphics terminals, and consumer medical devices. With USB device, CAN, and PMP graphics on-chip, the PIC32MX170F512L removes the need for external bridges in many embedded designs.
Design tip: at 40 MHz and full peripheral activity, power dissipation can reach roughly 75 mW (estimated from 2.5V/3.3V core supply and 33 mA run current); use the 100-pin TQFP copper pour to keep junction rise under 25 C/W. Decouple each AVDD/VDD pair with 0.1 uF plus 10 uF bulk capacitors placed within 5 mm of the pins.

Typical Applications
PIC32MX170F512L-V/PF is suitable for 6 applications: USB Audio Peripherals (USB Headset / DAC Interface), HMI / Capacitive Touch Panels, Industrial CAN Nodes (CANopen / DeviceNet), Low-Cost Graphics Terminals (PMP-driven LCD), Consumer Medical Devices (Patient Monitors), Portable Data Loggers with USB Connectivity.
USB Audio Peripherals (USB Headset / DAC Interface)
The PIC32MX170F512L-V/PF is a strong fit for USB audio peripherals because it integrates USB 2.0 full-speed device with on-chip PHY, two I2S modules, four SPI modules, and 64 KB of SRAM - enough to buffer small audio frames without an external codec bridge. Its 40 MHz MIPS M4K core delivers roughly 83 DMIPS of headroom for sample-rate conversion, mixer logic, and HID volume controls. The 100-pin TQFP exposes all 48 ADC channels and supports JTAG/ICSP debug, allowing rapid firmware iteration on audio tuning. Operating up to +105 C, it tolerates the thermal load inside enclosed headsets and powered speakers.
Recommended
HMI / Capacitive Touch Panels
The PIC32MX170F512L-V/PF suits HMI and capacitive touch panels thanks to its mTouch capacitive touch peripheral, CTMU for time-of-flight measurements, and Parallel Master Port (PMP) with dual buffers that can drive small TFT or OLED displays directly. With 64 KB of SRAM the device can hold a 320x240x16b framebuffer and UI state, removing the need for external SRAM in many terminals. The 100-pin TQFP exposes a generous number of GPIO via Peripheral Pin Select (PPS), so touch electrodes and display signals can be routed without re-spinning the PCB. Wide temp range allows deployment in industrial operator panels.
Recommended
Industrial CAN Nodes (CANopen / DeviceNet)
Industrial CAN nodes benefit from the PIC32MX170F512L-V/PF's integrated CAN 2.0B controller (up to 1 Mbps) plus the MIPS M4K core's deterministic interrupt latency. The 64 KB SRAM supports CANopen SDO buffers and DeviceNet fragmented message stacks without external memory. Five 16-bit timers allow precise PWM and event capture for motor/valve control loops. Operating from -40 C to +105 C, it fits unconditioned factory cabinets. The 100-pin TQFP also provides enough GPIO to read digital sensors and drive relays or solid-state outputs.
Recommended
Low-Cost Graphics Terminals (PMP-driven LCD)
The PMP module on the PIC32MX170F512L-V/PF provides dual read/write buffers and an 8-bit or 16-bit parallel interface ideal for direct connection to small TFT or character LCDs without an external graphics controller. With 512 KB Flash, designers can store multilingual font tables and full-screen bitmaps in-program, eliminating external Flash. The PPS function simplifies pin remapping when migrating between display sizes. 40 MHz core clock keeps screen refresh rates smooth at 320x240 and adequate for 480x272 panels.
Recommended
Consumer Medical Devices (Patient Monitors)
The PIC32MX170F512L-V/PF is well suited to consumer-grade patient monitors and home-health peripherals because of its 10-bit 1 Msps ADC, mTouch support for control surfaces, USB device for PC connectivity, and extended industrial temperature range. The MIPS M4K core can run simple DSP filters for pulse-oximetry or temperature sampling. CTMU enables precise resistance and capacitance measurements for low-cost sensor front-ends. AEC-Q100 is NOT qualified on this part, so it must not be used in automotive safety applications but is acceptable for consumer medical.
Recommended
Portable Data Loggers with USB Connectivity
Portable data loggers use the PIC32MX170F512L-V/PF for its 512 KB program Flash (ample for compression and sensor-protocol stacks), 64 KB SRAM for circular buffers, USB 2.0 FS device for file transfer, and CTMU for time-stamping events. The 40 MHz CPU can handle background SD-card writes via SPI while servicing USB enumeration. Extended -40 C to +105 C range supports outdoor and industrial field deployments. The 100-pin TQFP gives enough GPIO for multiple UART sensor buses plus SD card and USB connectors concurrently.

Key Differentiators
- Highest Flash/RAM in the 100-pin TQFP PIC32MX1XX family tier (vs PIC32MX150F256L-50I/PF)
- Extended +105 C operating range while keeping 40 MHz CPU (vs PIC32MX170F512L-50I/PF)
- Integrated USB 2.0 FS and CAN 2.0B on the same silicon (vs PIC32MX130F256L-50I/PF)
Design Notes
Estimated: at 40 MHz and full peripheral activity the PIC32MX170F512L core draws roughly 33 mA from a 3.3V rail, producing about 109 mW of internal dissipation. Place a 10 uF bulk plus 0.1 uF ceramic decoupling capacitor within 5 mm of each VDD/AVDD pin pair to keep the supply ripple under 50 mV and prevent code-fetch brownouts. The on-chip 1.8V regulator also needs its own 4.7 uF external cap per datasheet.
The 100-pin TQFP (14x14 mm, 0.5 mm pitch) is fine for hand-solderable prototypes but demands a 4-layer PCB with a continuous ground pour underneath to keep EMI low at USB full-speed (12 Mbps) and CAN (1 Mbps). Use Peripheral Pin Select (PPS) to remap USB D+/D- and CAN TX/RX away from high-switching GPIO, and length-match the differential USB pair within 2 mm. JTAG pins (PGECx/PGEDx) must be left accessible for MPLAB Snap / ICD programming.
Do not confuse speed grades: -V suffix caps the part at 40 MHz across +105 C, while -50I runs at 50 MHz but only up to +85 C. Programming voltages on the MCLR pin must observe the 9V ICSP sequence when using low-voltage programming mode, or 3.3V standard mode. The configuration bits include a debug-free bit that, once set, permanently disables JTAG; leave this off during development.
Compliance Information
