A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and peripherals such as timers, ADC, communication controllers, and GPIO. The PIC32MX1xx family sits in Microchip's PIC32 portfolio as an entry-level 32-bit MCU bridging the gap between PIC16/PIC24 8-/16-bit parts and high-performance PIC32MZ devices, offering ARM Cortex-M-class capability with the MIPS32 M4K core, and targeting industrial control, USB-connected embedded products, and graphical user interfaces.
Key features include the MIPS32 M4K core with hardware multiply/divide, 50 MHz operation, 512 KB Flash, 64 KB SRAM, full-speed USB 2.0 with OTG, four SPI/I2S modules, five UART, five I2C, PMP, 10-bit ADC up to 1 Msps, four 16-bit timers, and a peripheral pin select mapping fabric. The 100-pin TFBGA package provides 78 user I/O, suiting space-constrained designs that require extensive connectivity.
On the architecture side, the M4K core executes most instructions in a single cycle and supports DSP-style instructions for signal processing. The PPS feature lets peripheral signals be mapped to a wide range of pins, easing PCB layout, while the PMP block offloads graphics tasks from the CPU by handling external memory or display read/write cycles autonomously.
Typical applications include industrial control, USB peripherals (HID, CDC, MSD), low-cost graphics interfaces, home appliances, sensor hubs, and IoT edge nodes. The wide operating temperature range (industrial, -40C to +105C) and on-chip USB make it particularly suited to connected industrial devices.
When designing with this device, plan for a 2.3V to 3.6V supply; the part is single-core. Use MPLAB X IDE with the XC32 compiler and MPLAB Harmony for peripheral drivers to accelerate development. The 100-TFBGA requires PCB pads with 0.8 mm pitch - check your assembly house capability. The PIC32MX170F512L is a fully compatible same-die, same-pin, different-package variant for boards that prefer QFP.

典型應用
PIC32MX170F512LT-V/GJX 適用於 7 應用s: Industrial Control & Automation, USB Peripherals (HID, CDC, MSD, Vendor), Low-Cost Graphics Interfaces, Home Appliances & White Goods, IoT Edge Devices & Sensor Hubs, Connected Medical Accessories, Audio Codec & DSP Front-Ends.
Industrial Control & Automation
The PIC32MX170F512LT-V/GJX suits industrial controllers thanks to its 50 MHz/83 DMIPS MIPS32 M4K core and 64 KB SRAM, which handle real-time control loops, Modbus RTU/TCP stacks, and PID computation without offloading to a co-processor. The wide operating temperature range (-40C to +105C industrial grade) and USB 2.0 with OTG enable on-machine configuration, firmware update, and diagnostics via USB stick. The 100-TFBGA package reduces footprint for DIN-rail PLCs and HMI sub-modules where many I/O and signals coexist on a compact PCB.
推薦
USB Peripherals (HID, CDC, MSD, Vendor)
The PIC32MX170F512LT-V/GJX integrates a USB 2.0 Full-Speed controller with Device, Host, and OTG roles, eliminating an external USB interface chip and reducing BOM cost for HID keyboards, CDC virtual COM ports, MSD card readers, and custom vendor-class peripherals. The 48 MHz USB clock is derived from the on-chip PLL, removing the need for a USB-specific crystal. Microchip's MLA USB stack and Harmony framework supply ready-to-use HID, CDC, and MSD class drivers, cutting firmware development time from weeks to days for USB-enabled devices.
推薦
Low-Cost Graphics Interfaces
The PIC32MX170F512LT-V/GJX includes a Parallel Master Port (PMP) with dual read/write buffers that offload external memory and display read/write cycles from the CPU, making it well-suited for driving low-cost graphical LCDs and small TFT panels in appliance and industrial HMI designs. Combined with Peripheral Pin Select (PPS), PMP data, control, and address signals can be remapped to ease PCB routing. The 512 KB Flash accommodates graphic assets and framebuffer references, while the 64 KB SRAM keeps small UI buffers resident without external memory.
推薦
Home Appliances & White Goods
The PIC32MX170F512LT-V/GJX targets home appliances such as washing machines, induction cookers, smart ovens, and HVAC controllers where the combination of 50 MHz MIPS performance, USB diagnostics port, and industrial temperature range is highly valued. The 4 SPI/I2S modules enable codec and audio feedback for next-generation appliances with voice prompts, while the 5 UART handle multi-protocol connectivity (RS-485, RS-232, IR). The 512 KB Flash accommodates state-machine firmware and OTA update images for connected appliances.
推薦
IoT Edge Devices & Sensor Hubs
The PIC32MX170F512LT-V/GJX works as an IoT edge node aggregating sensor data over its 4 SPI/I2S, 5 I2C, and 5 UART interfaces, then forwarding pre-processed data via USB to a gateway or via UART to a wireless co-processor. The 50 MHz/83 DMIPS throughput handles edge filtering and thresholding before transmission, reducing wireless bandwidth requirements. The 64 KB SRAM supports ring buffers for multiple sensor streams, while 512 KB Flash stores persistent configuration and ML model weights for simple edge inference applications.
推薦
Connected Medical Accessories
The PIC32MX170F512LT-V/GJX serves connected medical accessories such as USB diagnostic tools, patient monitoring peripherals, and lab instrument interfaces that demand a stable USB link and a USB host for reading patient data from USB sticks. The 10-bit 1 Msps ADC captures analog sensor signals, while the 5 UART handle multi-channel medical sensor interfaces. The 100-TFBGA package and industrial temperature range suit compact, fan-less medical device enclosures with continuous operation requirements.
推薦
Audio Codec & DSP Front-Ends
The PIC32MX170F512LT-V/GJX handles low-power audio front-end tasks through its two I2S interfaces that connect directly to audio codecs, while four SPI modules drive additional DACs, ADCs, or display drivers. The MIPS32 M4K core executes DSP-style instructions (multiply-accumulate) for basic audio processing, filtering, and mix operations at 50 MHz. The 64 KB SRAM supports audio sample buffers, and USB OTG enables the device to function as a USB audio device. This combination makes the part a strong fit for USB speakers, headsets, and intercom panels.

設計說明
Decoupling: Place one 100 nF X7R 0402/0603 ceramic capacitor adjacent to each VDD pin and a single 10 uF X5R ceramic or low-ESR tantalum bulk capacitor within 5 mm of the IC. The PIC32MX170F512L is specified to operate from 2.3 V to 3.6 V; however, USB signaling requires a minimum of 3.0 V on the analog 3.3 V rail to meet USB 2.0 full-speed electrical specifications. Use a ferrite bead between the digital and analog 3.3 V rails if noise from the core couples into the USB transceiver. The on-chip voltage regulator generates 1.8 V internally for the core logic.
Layout for the 100-TFBGA package demands PCB pads with 0.65 mm ball pitch, microvia (laser-drilled) stack-ups, and a reflow profile compatible with lead-free (SAC305) solder. Verify the chosen assembly house supports 0.65 mm pitch BGA with appropriate stencil design (typically 0.4 mm aperture). Place decoupling capacitors on the top side directly under each VDD/VSS ball pair to minimize loop inductance. Keep the high-speed USB D+/D- traces matched within 2 mm and routed over a continuous ground reference; this is critical for USB 2.0 compliance and EMI.
Several common pitfalls should be avoided: (1) using a TQFP-100 footprint design when the BOM calls for the TFBGA-100 /GJX variant - the silicon is identical but the PCB pads are not interchangeable; (2) configuring USB without the 48 MHz USB PLL correctly - the system must use the on-chip PLL in USB PLL mode, not the primary oscillator directly; (3) not enabling Peripheral Pin Select (PPS) lock to prevent accidental remapping of UART/SPI/I2C pins at runtime; (4) leaving the ICSP/ICD pins (PGECx/PGEDx) unrouted - these are mandatory for in-system programming and debugging. Use MPLAB X IDE with XC32 compiler for firmware development.
Estimated: the PIC32MX170F512LT-V/GJX at 50 MHz core speed consumes approximately 30-40 mA typical active current at 3.3 V (around 100-130 mW). In a 100-TFBGA package with theta_JA around 35-45 C/W on a standard 4-layer JEDEC test PCB, the junction temperature rise above ambient is roughly 4-6 C under typical load - well within the -40C to +105C industrial operating range. For designs in enclosed housings without airflow, verify with thermal simulation, especially if USB host mode or full peripheral utilization is sustained.
