PIC32MX170F512L-V/PT 概要
What is a PIC32MX microcontroller? The PIC32MX1XX/2XX/5XX family is Microchip's mainstream 32-bit MIPS microcontroller line, bridging 8/16-bit PIC MCU users into 32-bit performance. Within the broader taxonomy, PIC32MX sits above 16-bit PIC24/dsPIC and below 32-bit PIC32MZ/Cortex-M4 devices, offering up to 83 DMIPS at 50 MHz with USB, CAN, and advanced peripherals. The '170' sub-family specifically targets audio/graphics/touch HMI applications with PMP graphics, I2S audio, and CTMU touch peripherals.
Key differentiating features include 512 KB self-programmable Flash, 64 KB SRAM, USB 2.0 full-speed OTG, CAN 2.0B, up to 13 ADC channels (10-bit 1 Msps), five 16-bit timers/counters, two comparators, and a Peripheral Pin Select that remaps most digital peripherals to any of the 100 pins. The integrated CTMU enables capacitive touch sensing for buttons, sliders, and proximity detection without external components.
The MIPS32 M4K core delivers 1.56 DMIPS/MHz and supports the MIPS16e instruction set for 40% code compression, freeing Flash for application code. Hardware Multiply/Divide unit executes 32x32 in one cycle. Single-cycle Flash access delivers deterministic performance at 50 MHz, with zero-wait-state execution from Flash prefetch cache. Compared to Cortex-M0+ parts at the same frequency, the PIC32MX170 offers substantially more SRAM and richer peripherals at modest power.
Typical applications include automotive HMI clusters, USB audio bridges, CAN-connected industrial sensors, graphic LCD controllers with PMP, capacitive touch user interfaces, and USB-CAN gateways. The AEC-Q100 qualification makes the -V (automotive) grade suitable for in-cabin automotive modules.
Design consideration: the PPS feature requires configuration via SFR writes at startup before the remapped peripherals operate, so initialize PPS in the first lines of main(). Decoupling requires 0.1 uF and 10 uF capacitors close to each VDD/VSS pair; the device has multiple VDD/VSS pins across the 100-TQFP layout.

設計ノート
Estimated: total power at 50 MHz core frequency with all peripherals active is approximately 60 mA from the 3.3 V rail, or about 200 mW. Decoupling requires at least one 0.1 uF ceramic and one 10 uF bulk capacitor per VDD/VSS pin pair. The PIC32MX170F512L-V/PT has multiple VDD/VSS pairs distributed across the 100-TQFP package to support the high-pin-count signal integrity. Place decoupling capacitors within 2 mm of each VDD pin. The core voltage is internally regulated from the 3.3 V supply; no external LDO is required for the MCU itself. Power-on-reset behavior is automatic; hold MCLR high through a 10 kohm pull-up with optional 0.1 uF decoupling.
Route the 50 MHz core clock trace as short and straight as possible. If using an external crystal, place the crystal within 5 mm of the OSCI/OSCO pins and surround the traces with a ground guard ring. For USB applications, route D+ and D- as a 90 ohm differential pair with length matching to within 2 mm. Place the USB series resistor (typically 27 ohm) within 5 mm of the USB connector. For PMP (Parallel Master Port) parallel interfaces, group the data bus lines together and add series damping resistors if the bus exceeds 50 mm total length to reduce overshoot on a QVGA TFT panel.
Peripheral Pin Select (PPS) registers must be configured at startup before any remapped peripheral can operate. Failing to initialize PPS in the first lines of main() is the most common cause of dead peripherals. Additionally, the CTMU mTouch library requires careful PCB layout - keep the touch sensor traces short, surrounded by ground fill, and away from switching signals to prevent false touches. For automotive V-grade designs targeting +105C operation, verify that all external components (capacitors, crystal) are rated for the same temperature range. Finally, ensure ICSP programming pins PGECx/PGEDx are accessible on the production PCB for firmware updates.
