PIC32MX170F512LT-I/GJX Overview
A 32-bit microcontroller (MCU) is a programmable integrated circuit that executes instructions from on-chip Flash memory, featuring a 32-bit data path, multiple timers, ADC/DAC peripherals, and communication interfaces. Microcontrollers sit within the hierarchy microcontroller -> embedded processor -> semiconductor IC and form the core of nearly every modern embedded electronic product.
Key features of the PIC32MX170F512L family include 50 MHz core frequency with single-cycle multiply and divide, Peripheral Pin Select (PPS) for flexible signal assignment, two I2S and four SPI modules for audio codec interfaces, a Parallel Master Port (PMP) with dual buffers for graphics, plus USB 2.0 full-speed device/host/OTG capability. Additional peripherals include a 10-bit 1 Msps ADC, three analog comparators, Capture/Compare/PWM, RTCC, and CTMU for touch and capacitive sensing.
Technically the PIC32MX170 uses the MIPS32 M4K core with 5-stage pipeline, hardware multiply/divide, and 32 KB of prefetch cache that masks Flash latency. Its 5 V tolerant digital I/O (with proper configuration) and PPS remapping reduce PCB layout constraints and let the factory tail gate assignment migrate between board revisions. The CTMU and RTCC blocks add accurate time measurement for metering and battery-backed timekeeping applications.
Typical applications include USB audio interfaces, industrial HMI panels with TFT graphics, point-of-sale terminals, smart energy metering, and IoT edge nodes. Its combination of 512 KB Flash and 64 KB RAM supports TCP/IP stacks, USB device classes, and graphics libraries running concurrently. When designing with this device, ensure the 100-ball TFBGA land pattern uses NSMD pads with via-matchup layout and an explicit draw order of assembly checklist for proper 0.5 mm pitch BGA assembly - non-compliant BGA reflow profiles can cause head-in-pillow defects.

Key Differentiators
- Higher core frequency for compute-bound designs (vs PIC32MX170F512LT-50I/GJX)
- 12-bit ADC for precision measurement (vs PIC32MX270F512LT-I/GJX)
- Full 512 KB Flash retention in same package (vs PIC32MX150F256LT-I/GJX)
Design Notes
The 100-TFBGA package uses a 0.5 mm ball pitch which demands NSMD land pads with via-matchup layout per Microchip IPC-7351 footprint guidelines. Use an explicit draw order of assembly checklist for proper 0.5 mm pitch BGA assembly - non-compliant BGA reflow profiles can cause head-in-pillow defects. Plan for at least 4 PCB layers with a continuous ground plane beneath the BGA to provide thermal dissipation and reference return paths for high-speed signals.
The PIC32MX170F512LT-I/GJX operates from 2.3 V to 3.6 V across the industrial -40C to +85C range. Decouple VDD with at least one 10 uF bulk capacitor and one 100 nF ceramic capacitor per VDD pin pair, placed within 5 mm of the package. For USB applications, the VBUS pin requires separate regulation per the USB 2.0 specification with bypass capacitors per the on-the-go USB-Spec for full-speed OTG guidelines.
Peripheral Pin Select (PPS) allows remapping of digital peripherals to any I/O pin, but input pins are limited to specific fixed-function pins per the device datasheet. Attempting to map an input peripheral to a non-input-capable pin results in silent signal failures. Always consult the device datasheet's PPS input map before committing to a PCB layout. For second-order clock configurations, ensure the SYSCLK frequency does not exceed the crystal or oscillator drive strength limit at low frequencies like 32 kHz.
Compliance Information
RoHS and REACH compliant per Microchip product page. Industrial -40C to +85C temperature range; not AEC-Q100 qualified - automotive grade not available in this variant.
