PIC32MX460F256L-80I/BG Présentation
What is a PIC32 microcontroller? A PIC32MX device is a 32-bit flash microcontroller built on the MIPS M4K core, combining the deterministic peripheral set of Microchip's classic PIC architecture with the throughput of a 32-bit RISC pipeline. PIC32MX MCUs sit within Microchip's broader MCU hierarchy: 32-bit MCU -> MIPS-based MCU -> PIC32 family -> PIC32MX general-purpose series -> USB-capable sub-series. Compared to 8-bit PIC16/PIC18 devices, the PIC32MX adds native 32-bit registers, hardware multiply/divide, and significantly higher code density for C-based firmware.
The 256 KB Flash supports in-application programming through the ICSP interface, while 32 KB of SRAM enables substantial buffering for USB, communication stacks, and signal-processing tasks. The 80 MHz core delivers 1.56 DMIPS/MHz (approximately 125 DMIPS), supporting real-time USB, graphic, and control-loop workloads. Integrated peripherals include a 16-channel 10-bit ADC, five 16-bit timers, an RTCC, and a parallel master port for external bus expansion.
USB 2.0 full-speed OTG with on-chip transceiver eliminates external PHY cost and board area. The 121-pin TFBGA package maximizes I/O availability with 85+ general-purpose I/O pins, supporting both 2.5 V and 3.3 V operation across industrial temperature ranges (-40°C to +85°C).
Typical applications include USB peripherals, industrial control HMI panels, medical point-of-care instruments, embedded web servers, and motor-control front-ends. The 80 MHz MIPS performance combined with deterministic interrupt latency makes the PIC32MX460 suitable for hard real-time control alongside USB communication.
When designing with this part, ensure the 121-ball TFBGA land pattern is correctly routed with proper thermal vias under the package. Use MPLAB XC32 compiler with appropriate optimization levels for size and speed trade-offs in USB stack builds.

Principaux différenciateurs
- Integrated USB 2.0 FS OTG with on-chip transceiver (vs PIC32MX360F256L-80I/BG)
- Same 121-TFBGA footprint across PIC32MX4 family (vs PIC32MX360F512L-80V/BG)
- Higher temperature option available within same footprint (vs PIC32MX460F256L-80V/BG)
Notes de conception
The 121-TFBGA package requires 4-layer PCB with continuous ground plane beneath the BGA to provide reference and thermal dissipation. Use 0.4 mm ball pitch with NSMD (non-solder mask defined) pads of 0.30 mm diameter for reliable reflow assembly. Microvia-in-pad technology is recommended for breakout routing to inner layers, and an array of thermal vias under the center pad is essential for heat dissipation at 80 MHz operation.
Use a 10 µF bulk capacitor plus 0.1 µF ceramic bypass capacitor on each VDD pin pair. The VUSB pin requires a dedicated 0.1 µF decoupling capacitor placed within 2 mm of the pin to stabilize the USB transceiver supply. Place a ferrite bead or inductor between VDD and VUSB to isolate digital switching noise from the USB analog supply. Reference: Microchip PIC32MX family datasheet, Section 2.0 (Electrical Characteristics) and reference design DN10269.
Do not exceed 80 MHz core clock with 2.5 V VDD - the part only supports 80 MHz at 3.3 V. Configure the PLL multiplier carefully when using a low-frequency crystal; the FPLLIDIV and FPLLMUL registers must be sequenced per the datasheet. The MCLR pin must have a 10 kΩ pull-up to VDD for reliable reset behavior, and unused I/O pins should be configured as outputs driven low to minimize power consumption.
Route the USB D+/D- traces as a 90-ohm differential pair with matched length within 150 mil. Keep them away from switching signals and clock traces to minimize EMI and meet USB 2.0 FS signal integrity requirements. Place the USB connector's shield-to-ground connection through a ferrite bead to reduce EMI emissions per USB-IF compliance testing.
Informations de conformité
RoHS compliant per Microchip product page. Industrial temperature grade (-40 to +85C) but not AEC-Q100 qualified for automotive under-hood use. For AEC-Q100 qualified USB MCUs, consider PIC32MX1xx/2xx automotive variants.
