What is a PIC32MX microcontroller? PIC32MX is Microchip's MIPS32 M4K-based MCU family positioned between 16-bit dsPIC/PIC24 and Cortex-M-class parts. It uses a Harvard-architecture 32-bit core with single-cycle multipliers, deterministic interrupt latency, and 16-bit instructions for code density, while remaining compatible with classic PIC peripherals. PIC32MX parts are widely used in HMI, USB audio, and industrial control designs.
Key features of the PIC32MX170F512L include 50 MHz / 83 DMIPS performance, 512 KB Flash with pre-fetch cache, 64 KB RAM, USB 2.0 full-speed OTG, CAN 2.0B, two I2S, four SPI, five UART, five I2C, PMP for external memory/graphics, a 16-channel 10-bit 1 Msps ADC, five 16-bit timers/capture/compare, an RTCC, and Peripheral Pin Select (PPS) for nearly every digital function.
The M4K core uses a 5-stage pipeline with branch shadowing and a hardware multiply/divide unit; Flash is mirrored into the 32-bit instruction fetch path through a 128-bit wide bus with a 4-word pre-fetch cache, while data passes through a separate SRAM bus, eliminating single-cycle Flash wait states in most cases.
Typical applications include USB audio interfaces (USB + I2S + DAC chains), HMI panels with LCD via PMP, industrial CAN nodes, capacitive touch keypads, motor-control sequencers, and low-cost graphics + USB dongles. Industrial temperature grade (-40C to +85C) and the 100-pin TQFP give enough I/O for layered systems.
Design consideration: when migrating from PIC24/dsPIC or PIC32MX3/4/5/6/7 families, verify PPS mapping because PIC32MX1xx has fewer remappable pins and a smaller RAM/Flash than PIC32MX5/6/7. Decoupling must include a 100 nF per VDD/AVDD pair and a bulk 4.7 uF on VDDCORE.

Ứng dụng tiêu biểu
PIC32MX170F512L-I/PT phù hợp cho 6 Áp dụngs: USB Audio Headset / Sound Card, HMI Panel with Graphics LCD, Industrial CAN Node, Capacitive Touch Keypad, USB Barcode / Magnetic-Stripe Reader, IoT Sensor Aggregator.
USB Audio Headset / Sound Card
The PIC32MX170F512L-I/PT's combination of Full-Speed USB 2.0 On-The-Go and two I2S ports makes it well suited for USB-to-I2S audio interfaces, including headsets, USB DACs, and USB microphones. The 50 MHz MIPS32 M4K core sustains 83 DMIPS, sufficient for sample-rate conversion and volume control at 48 kHz/24-bit; it issues two ANSI/USB audio class commands. The two I2S lanes support independent stereo paths for headphone and line outputs. The I2S interface pairs naturally with the PIC32MX270F512L-I/PT for higher sample rates.
Được đề xuất
HMI Panel with Graphics LCD
The PIC32MX170F512L-I/PT integrates a Parallel Master Port (PMP) with dual read/write buffers, enabling direct connection to small graphics LCDs without an external frame buffer. The 100-pin TQFP gives enough I/O to run an 8/16-bit PMP bus plus mTouch capacitive touch channels for buttons. The 83 DMIPS performance is enough to draw 4-bpp widgets and handle UI state machines. PMP timing is programmable and matches common 320x240 QVGA panels.
Được đề xuất
Industrial CAN Node
The PIC32MX170F512L-I/PT pairs its CAN 2.0B controller with five UART and PMP, fitting industrial CAN nodes that need a sensor bridge or small HMI. The 50 MHz MIPS32 M4K core runs CANopen and DeviceNet stacks without burden; the industrial -40C to +85C rating and 100-pin TQFP give sufficient GPIO for parallel digital inputs. An external CAN transceiver such as MCP2551 or TJA1050 is required. PIC32MX270F512L-I/PT is the higher-throughput upgrade.
Được đề xuất
Capacitive Touch Keypad
Microchip's mTouch library and CTMU peripheral let the PIC32MX170F512L-I/PT implement capacitive touch sensing for human-machine interfaces. The 16 ADC channels and CTMU provide up to 16 touch buttons or a 4x4 matrix with proximity detection, suitable for appliances, door locks, and consumer devices. The 100-pin TQFP brings ample I/O for shared LED scanning, and PPS lets you remap sensor channels to any spare pin.
Được đề xuất
USB Barcode / Magnetic-Stripe Reader
The PIC32MX170F512L-I/PT's USB OTG and 512 KB Flash are sized for embedded USB peripherals such as barcode scanners, magnetic-stripe readers, and RFID HID bridges. The PIC32MX USB stack handles HID/CDC/MSD classes; the dual I2S ports are unused, freeing them for diagnostic logging. The -40C to +85C industrial range covers retail and warehouse environments. PIC32MX170F512L-50I/PT is the speed-graded equivalent.
Được đề xuất
IoT Sensor Aggregator
The PIC32MX170F512L-I/PT acts as a sensor aggregator: it pulls data over UART/I2C/SPI from environmental or motion sensors and forwards it via USB, CAN, or a wireless module on a UART. The 50 MHz MIPS32 M4K core, 64 KB RAM, and PPS flexibility support multiple serial buses simultaneously. mTouch/CTMU and the 16-channel ADC add analog and capacitive front-ends. PIC32MX270F512L-I/PT is the higher-speed IoT gateway upgrade.

Ghi chú thiết kế
The PIC32MX170F512L-I/PT integrates a 1.8 V core LDO. Decoupling must include a 100 nF ceramic on each AVDD/VDD pin pair and a bulk 4.7 uF on VDDCORE. If USB is enabled, VUSB_3V3 must be tied to VDD through a ferrite bead to avoid back-drive; USB bus-powered designs need a 5V-tolerant source (Microchip ANSLU610). Estimated VDDIC quiescent is approximately 15-25 mA at 50 MHz with full peripheral toggle, so keep an external LDO headroom of at least 250 mA for USB hot-plug.
Route the USB D+/D- differential pair with 90 ohm differential impedance and a maximum length of 50 mm. The 12 MHz crystal traces should be short and symmetric, with the load capacitors placed as close to the OSC1/OSC2 pins as possible. For PMP-driven graphics LCDs, place the panel connector next to the PMP pins (RE0-RE7, RD0-RD7, RG2-RG3) to avoid bus turnaround issues at 25 MHz.
Peripheral Pin Select (PPS) is not available on every pin; the datasheet pinout specifies which pins are input-only vs output-only remappable. Designers often forget that PPS remap assignments are unlocked via CFGCON, and that mappable pins default to GPIO at reset. Avoid using RG6-RG9 as remapped outputs since they are 5V-tolerant only and can conflict with JTAG/ICSP programming pins. Always verify the 100-pin TQFP pinout versus the part marking '-I/PT'.
The PIC32MX170F512L-I/PT's I/O drive strength is rated at 10 mA source/sink, with low-current option of 5 mA. For SPI/I2C buses that are heavily loaded, enable slew-rate limiting by clearing the SRCRE bit on the relevant port. The CTMU-driven mTouch inputs should be guarded with a 100 ohm ferrite to reduce coupled noise from PWM outputs.
