PIC32MX460F256LT-80V/BG Visão geral
A 32-bit microcontroller (MCU) is a programmable system-on-chip that combines a 32-bit processor core, on-chip non-volatile program memory, volatile data memory, and a rich set of digital and analog peripherals. The PIC32MX family sits in Microchip's PIC32 hierarchy (PIC32MX -> PIC32 -> MIPS M4K core -> 32-bit MCU -> microcontroller -> semiconductor) and targets cost-sensitive embedded designs that need more performance and memory than 8/16-bit PIC MCUs while retaining a familiar MPLAB X toolchain.
Key features include 80 MHz core clock, 256 KB Flash program memory (256K x 8 organization), 32 KB SRAM, USB 2.0 Full-Speed On-The-Go (OTG) with dedicated DMA, 16-channel 10-bit 1 MSPS ADC, five 16-bit timers/counters, I2C, SPI, UART, PMP/EPMP parallel bus, and JTAG/ICSP debug. The device operates from 2.3 V to 3.6 V and is rated -40C to +105C (V-temp) for industrial-grade deployments.
Architecturally, the PIC32MX460 implements a 5-stage MIPS32 M4K pipeline with hardware multiply/divide, single-cycle Flash prefetch, and a peripheral bus running at half the system clock. The dedicated USB OTG controller with on-chip transceiver simplifies USB device/host/OTG designs without an external PHY, while the 10-bit ADC supports up to 16 analog inputs with automatic channel scanning.
Typical applications include USB peripherals (HID, CDC, mass storage, audio), industrial control boards, embedded HMI with PMP-driven TFT displays, sensor hubs, and consumer audio products that need a 32-bit core plus USB connectivity.
When designing in this part, plan for a 2-layer PCB with a solid ground pour under the TFBGA; route USB DP/DN as a 90 ohm differential pair and place the VBUS ESD array within 3 mm of the connector. The -80V suffix indicates the 80 MHz speed grade with -40C to +105C operating temperature (V-temp industrial).

Aplicações típicas
PIC32MX460F256LT-80V/BG é adequado para 6 aplicaçãos: USB HID Peripheral (Keyboard/Mouse/Gamepad), USB CDC Virtual COM Port Bridge, Industrial Sensor Hub with USB Logging, Embedded HMI with PMP-Driven TFT Display, USB Audio Class Speaker / Headset Dongle, USB Mass Storage / Data Logger.
USB HID Peripheral (Keyboard/Mouse/Gamepad)
The PIC32MX460F256LT-80V/BG is a strong fit for USB HID peripherals because the integrated USB 2.0 Full-Speed OTG controller with on-chip transceiver eliminates the need for an external USB PHY, saving roughly $0.30-0.60 of BOM cost and 50-80 mm² of board area. At 80 MHz the M4K core runs HID report handling and debounce logic with ample headroom, while 32 KB SRAM holds HID report buffers and protocol state. The 256 KB Flash accommodates USB stack (Microchip MLA), HID class driver, and application code. Designers should route the DP/DN lines as a 90 ohm differential pair with traces under 50 mm, place the VBUS 4.7 uF capacitor within 3 mm of the VBUS pin, and add TVS protection (e.g., USBLC6-2SC6) within 5 mm of the connector.
Recomendado
USB CDC Virtual COM Port Bridge
For USB-to-UART bridge designs the PIC32MX460F256LT-80V/BG provides a CDC class-compliant USB device with up to 12 Mbps full-speed throughput. The integrated USB OTG controller with dedicated DMA offloads bulk endpoint transfers, freeing the CPU for buffering and protocol handling. The 32 KB SRAM accommodates CDC line-coding state and ring buffers, while 256 KB Flash holds the MLA USB stack, CDC class driver, and any command-processing firmware. Compared to dedicated bridges like the FT232, the PIC32MX460F256LT-80V/BG allows custom command parsing and GPIO expansion. Recommended practice: enumerate at Full-Speed only, use bulk OUT endpoint for downstream data, and add a 1.5 kohm pull-up on D+ for device-mode signaling.
Recomendado
Industrial Sensor Hub with USB Logging
Industrial sensor hubs benefit from the PIC32MX460F256LT-80V/BG's 16-channel 10-bit ADC at 1 MSPS, 5 x 16-bit timers, and USB-OTG for logged data offload. The 80 MHz core runs sampling, averaging, and USB bulk transfers in parallel without missing samples. At 2.3-3.6 V and -40C to +105C V-temp, the part operates from industrial 3.3 V rails and inside unheated enclosures. The 32 KB SRAM buffers acquisition frames before USB transfer, and 256 KB Flash holds the USB stack plus application code. Compare against the PIC32MX450F256L-V/PF when USB is not required - same Flash/RAM but no USB block (-15% cost) and the same 121-TFBGA footprint for layout reuse.
Recomendado
Embedded HMI with PMP-Driven TFT Display
HMI boards that drive small TFTs through the Parallel Master Port (PMP/EPMP) benefit from the PIC32MX460F256LT-80V/BG's dedicated PMP peripheral and 32 KB SRAM frame buffer. The 80 MHz core and 16-bit PMP data width refresh QVGA/WQVGA panels at 30+ Hz with the CPU mostly idle. USB-OTG serves HID touch input or remote firmware update, while 256 KB Flash holds Microchip's Graphics Library plus USB stack. Use 8-bit or 16-bit PMP mode depending on panel bus width, place a 100 ohm series ferrite bead on each LED backlight rail, and tie unused PMP pins to defined logic levels to avoid CMOS input floating current.
Recomendado
USB Audio Class Speaker / Headset Dongle
USB audio devices like speakers, headsets, and microphones leverage the PIC32MX460F256LT-80V/BG's isochronous USB endpoints and 10-bit ADC/DAC. Although a 10-bit converter is modest for hi-fi audio, it is sufficient for voice-grade intercoms, USB microphones, and intercom dongles. The 32 KB SRAM holds one isochronous frame of USB audio samples (44.1 kHz stereo at 10 ms frame = 176 samples), and the 80 MHz core manages sample-rate conversion with headroom. For higher fidelity, cascade with an external 16/24-bit DAC (e.g., PCM5102A) driven via I2S bit-banged on the PMP pins. Add a ferrite bead on the analog AVDD rail and keep DP/DN traces short.
Recomendado
USB Mass Storage / Data Logger
USB mass-storage class devices and data loggers benefit from the PIC32MX460F256LT-80V/BG's USB OTG with bulk transfer DMA plus 32 KB SRAM for FAT table caching. 256 KB Flash holds the USB MSC class driver, FAT file system, and logging firmware. The 80 MHz core sustains 800-900 KB/s typical full-speed USB throughput, enough for SD card mirroring, EEPROM programmers, and CSV loggers. The 10-bit ADC samples sensor channels while the USB stack moves bulk data off-chip. Recommended practice: use bulk-only transport, add a 100 uF bulk capacitor on VBUS for hot-plug events, and qualify the FAT implementation against Windows/MacOS/Linux write behaviors.

Principais diferenciais
- Integrated USB 2.0 Full-Speed OTG with on-chip transceiver (vs PIC32MX360F256L-80V/BG)
- V-temp (-40C to +105C) operating range (vs PIC32MX460F256LT-80I/BG)
- Highest pin-count 121-TFBGA package exposes full peripheral set (vs PIC32MX450F256L-V/PF)
Notas de projeto
Estimated: For the 121-TFBGA (BG) package with 0.8 mm ball pitch, use a 4-layer PCB with a solid ground plane beneath the BGA and 1 oz copper. Microvia-in-pad is recommended for inner-row balls; outer-row balls can use standard fan-out to 0.5 mm pitch escape traces. Place the 8 MHz crystal (or 12 MHz for USB-only firmware) within 5 mm of OSCI/OSCO, route OSCI/OSCO over a continuous ground pour, and add a 100 ohm ferrite bead on AVDD before decoupling to suppress analog switching noise.
Route USB DP/DN as a 90 ohm differential pair with trace lengths matched within 1 mm, maximum trace length 50 mm, and keep the pair over a continuous ground reference plane (no splits). Add a 4.7 uF X5R bulk capacitor on VBUS within 3 mm of the BGA VUSBPWR/VBUS pin, and place a TVS array such as USBLC6-2SC6 within 5 mm of the USB connector. Stitching vias every 5 mm along the ground pour around the USB pair reduce common-mode EMI by 8-10 dB.
Do not enable the USB module without configuring the 48 MHz USB clock from the PLL with the correct reference oscillator - if the PLL is set to the 8 MHz crystal, the USB peripheral will enumerate at non-compliant frequencies and fail USB-IF compliance tests. Also, the -80V V-temp variant is intended for industrial/automotive cabin modules, not automotive under-hood (AEC-Q100); for under-hood designs use PIC32MX1xx/2xx AEC-Q100 qualified parts instead. Finally, do not enable JTAG fuses unless you have an MPLAB REAL ICE or ICD-4 capable of recovering the part via 2-wire ICSP.
