PIC32MX460F512L-80I/BG Übersicht
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals (UART, I2C, SPI, ADC, timers, USB) into one package. Within the semiconductor taxonomy, an MCU belongs to the broader category of microcontrollers -> microprocessors -> logic ICs -> integrated circuits. The PIC32MX family is Microchip's highest-performance 32-bit general-purpose line, succeeding the legacy 16-bit PIC24/dsPIC families and competing head-to-head with ARM Cortex-M3 MCUs from STMicroelectronics and NXP. Its MIPS M4K core, 5-stage pipeline, and hardware multiply/divide unit make it well suited to real-time embedded control with USB connectivity.
Key features include 512 KB (512K x 8) Flash, 32 KB SRAM, full-speed USB 2.0 On-The-Go (OTG), a 10-bit 1 Msps ADC with up to 16 channels, four UARTs, two I2C and two SPI ports, five 16-bit timers/counters, and a parallel master port (PMP) for graphics or external memory. The integrated USB-OTG controller eliminates an external PHY and is one of the differentiators against smaller PIC32MX3xx variants.
Typical applications include USB peripherals (HID, CDC, mass storage), industrial control and HMI panels, embedded audio and consumer products, low-cost graphical displays driven through PMP, and hobbyist/education development boards (e.g., the Olimex PIC32-MX460). The wide industrial temperature grade and 512 KB Flash also make it suitable for protocol-converter gateways and small IoT edge nodes.
When designing with this part, reserve one of the 121 BGA balls for the dedicated JTAG/ICSP pair (PGECx/PGEDx) and keep the trace length to the programming connector short to ensure reliable In-Circuit Serial Programming. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes that go beyond what is printed in the Microchip datasheet.

Typische Anwendungen
PIC32MX460F512L-80I/BG ist geeignet für 6 Anwendungs: USB HID / CDC / Mass-Storage Peripherals, Industrial HMI and Graphical Panels, Protocol Converter and IoT Edge Gateways, Embedded Audio Consumer Products, Industrial Control and Data Acquisition, Hobbyist Development and Education Boards.
USB HID / CDC / Mass-Storage Peripherals
The PIC32MX460F512L-80I/BG's integrated USB 2.0 Full-Speed On-The-Go controller with on-chip transceiver is the primary reason engineers choose this MCU over smaller PIC32MX3xx parts. With 512 KB Flash and 32 KB SRAM the device comfortably fits full USB class drivers plus a custom application - e.g., a 53 KB HID stack plus CDC composite plus 200 KB of application code. The 80 MHz MIPS M4K core delivers the throughput needed to sustain USB Full-Speed (12 Mbps) endpoints without starving the main loop, and the part supports host, device, and OTG roles. In a typical layout, the USB DP/DN pair is routed as a 90-ohm differential with the 48 MHz USB clock sourced from the primary oscillator or the internal PLL.

Industrial HMI and Graphical Panels
The PIC32MX460F512L-80I/BG drives small QVGA/WQVGA TFT panels directly through its Parallel Master Port (PMP), which is one of the differentiators of the 460-class against 440/450 siblings. With 512 KB Flash the device can hold full graphics libraries, font tables, and multi-language strings for an industrial control panel. The 80 MHz core is sufficient for 60 Hz refresh on small TFTs without an external graphics controller, and the 32 KB SRAM is enough for two frame buffers in 16-bit color. The industrial -40C to +85C grade plus 2.5/3.3 V supply fits factory-floor PLC HMIs where wide temperature tolerance is mandatory.
Empfohlen
Protocol Converter and IoT Edge Gateways
The PIC32MX460F512L-80I/BG works as a protocol-converter gateway between industrial buses (RS-232/485 via UARTs), I2C sensors, SPI peripherals, and USB host to log or forward data. With four UARTs, two I2C, and two SPI ports the MCU handles multi-bridge topologies, and the 512 KB Flash accommodates full Modbus, CANopen, or MQTT client stacks. The 80 MHz MIPS M4K core sustains encrypted TLS handshakes on small payloads and the DMA channels offload peripheral transactions so the CPU stays free for application logic.
Empfohlen
Embedded Audio Consumer Products
The PIC32MX460F512L-80I/BG's 80 MHz core, DMA, and 32 KB SRAM support 16-bit 48 kHz audio I2S or DAC playback streams driven via SPI or the PMP in consumer audio accessories, toys, and novelty products. The 512 KB Flash stores minutes of compressed audio clips and the DMA offloads sample streaming, leaving CPU headroom for control loops. The industrial temperature grade plus 3.3 V single-supply operation simplifies power-tree design in battery-powered or USB-powered speaker products.
Empfohlen
Industrial Control and Data Acquisition
The PIC32MX460F512L-80I/BG's 10-bit 1 Msps ADC with up to 16 channels, plus five 16-bit timers, suits motor-control and analog-sensing applications in industrial environments. The 80 MHz core sustains 10 kHz PID loops on BLDC or stepper motor drives, and the DMA channels move ADC samples to RAM without CPU overhead. The -40C to +85C industrial temperature grade and 2.5/3.3 V supply match 24 V industrial bus systems via a small LDO. The 512 KB Flash also stores calibration tables, fault logs, and Modbus register maps.

Hobbyist Development and Education Boards
The PIC32MX460F512L-80I/BG is the silicon used on Olimex PIC32-MX460, MikroElektronika EasyPIC FUSION v7 MCU cards, and similar education platforms, taking advantage of the 121-ball TFBGA footprint for full peripheral access. With MPLAB X IDE, MPLAB Harmony, and PICkit 5 support, the part is widely used in academic 32-bit MCU courses, hobbyist USB tutorials, and open-source retro-gaming projects (e.g., NES emulator ports). The 80 MHz core, 512 KB Flash, and FreeRTOS compatibility make it a practical teaching example for students transitioning from 8-bit PIC16/18 to 32-bit MIPS or ARM architectures.

Designhinweise
The 121-ball TFBGA (BG) package has a 0.8 mm ball pitch, which is hand-solderable only with hot air or BGA rework stations. Use 4-layer PCB with continuous GND plane under the BGA to improve signal integrity and thermal dissipation; a single-keeper is acceptable for prototypes but reduces noise immunity on USB DP/DN lines. Fanout microvias-in-pad (VIP) or via-in-pad plating is recommended for inner balls to maximize breakout escape density.
Route the USB DP/DN pair as a 90-ohm differential with no stubs, length matching within 150 mils. Place a 100 nF decoupling capacitor within 3 mm of every VDD ball and a 4.7 uF bulk cap near the package per the family datasheet (DS61143H). Keep the 48 MHz USB clock trace short and isolated - noise on this signal directly degrades USB eye diagrams and causes enumeration failures.
Do not omit the PGECx/PGEDx pair - In-Circuit Serial Programming (ICSP) and JTAG rely on dedicated balls that must be routed to the programming connector with short traces. Configuration bits set at end-of-programming must match the supply voltage (2.5 V vs 3.3 V) or the part may fail to start. Disable the JTAG port in production configuration bits if you intend to reuse the JTAG pins as GPIO, otherwise they remain locked.
At 80 MHz the PIC32MX460F512L-80I/BG core dissipates approximately 60 mA from the 3.3 V supply. The 121-ball TFBGA has a thermal resistance of approximately 22 C/W (estimated, no official figure in provided data); under industrial -40C to +85C operation this is well within margin. For extended designs at >70 MHz with all peripherals active, ensure the inner balls are stitched to the ground plane for both electrical and thermal benefit.
Place the 4.7 uF bulk decoupling cap and a 100 nF ceramic cap within 5 mm of the VDD/VSS balls. For designs using the parallel master port (PMP) to drive a TFT, isolate the PMP data bus from the USB DP/DN pair with a GND trace to avoid TFT-switching noise coupling into the USB eye. Estimated: GND stitching vias every 200 mils around the BGA perimeter improve HF return paths.
Compliance-Informationen
RoHS compliance and REACH unaffected status per GlobalSpec distributor listing 2026-10-03. AEC-Q100 not applicable for commercial/industrial MCU use; Microchip publishes separate automotive-grade parts (e.g., dsPIC33 variants).
