PIC32MX775F512L-80V/BG Übersicht
A 32-bit microcontroller is a programmable processor that executes instructions from on-chip memory, exposes configurable peripherals, and serves as the central compute unit of an embedded system. Within the broader semiconductor hierarchy it sits inside the microcontroller family, which itself belongs to logic ICs, integrated circuits, and ultimately to the wider electronics component taxonomy. The PIC32MX5/6/7 family uses a Harvard-class MIPS32 core paired with Microchip's peripheral library, and is fully supported by the MPLAB Harmony integrated software framework, MPLAB X IDE, and XC32 compiler toolchain. This puts the PIC32MX775F512L-80V/BG in the application-processor tier of microcontrollers, with on-chip connectivity IP that historically required an external MAC plus PHY.
Differentiating features include the integrated Ethernet MAC, USB-OTG full-speed controller, two independent CAN 2.0b modules, a 16-channel 10-bit 1 Msps ADC, and a parallel master port for external memory. DMA, five 16-bit timer/counters, and four IC SPI interfaces further offload the core. A 10-bit ADC combined with DMA enables deterministic analog sampling for motor, sensor, and power-conversion feedback loops.
Typical deployments include industrial gateways, factory-automation controllers, automotive telematics modules, medical patient monitors, USB-OTG device or host peripherals, and Ethernet-attached data-acquisition nodes. The 512KB code region supports the TCP/IP stack plus application code without external boot memory, while dual CAN enables bridge-node access in a CAN-Ethernet gateway. Design considerations include signal integrity on the 80MHz LVPBA outputs, supply decoupling of the analog AVDD rail to preserve 10-bit ADC linearity, and thermal performance inside the 10x10mm TFBGA footprint for sustained Ethernet + USB workloads.

Typische Anwendungen
PIC32MX775F512L-80V/BG ist geeignet für 6 Anwendungs: Industrial Ethernet Gateway, Automotive CAN-Ethernet Bridge, USB-OTG Field Peripheral, Medical Patient Monitor, Smart Sensor Hub with Ethernet, Industrial Data Acquisition Front End.
Industrial Ethernet Gateway
The PIC32MX775F512L-80V/BG fits industrial Ethernet gateways because its integrated 10/100 Mbit MAC and dual CAN interfaces allow a single MCU to bridge CAN fieldbus traffic to a TCP/IP network without an external processor. With 512 KB of Flash, designers can embed the Microchip TCP/IP stack plus a TLS or Modbus library while leaving room for application logic. The 80 MHz MIPS32 M4K provides 1.56 DMIPS/MHz throughput, which is sufficient to service concurrent Ethernet, CAN, and serial traffic without dropping packets. The -40C to +105C operating range suits factory-floor enclosures, and the 121-TFBGA keeps the PCB footprint compact behind the RJ45 connector.
Empfohlen
Automotive CAN-Ethernet Bridge
In automotive telematics and body controllers, the PIC32MX775F512L-80V/BG works as a CAN-to-Ethernet bridge because two independent CAN 2.0B controllers handle automotive bus traffic and the on-chip Ethernet MAC uplinks to a gateway ECU. The 64 KB SRAM is large enough to buffer CAN frames while the TCP/IP stack processes them for remote diagnostics. 80 MHz core throughput keeps gateway latency predictable, and the 10-bit 1 Msps ADC allows direct sampling of analog sensors alongside bus traffic. Designers must still respect AEC-Q100 sourcing rules and use the -Q1 automotive variant where certification is mandatory.
Empfohlen
USB-OTG Field Peripheral
The PIC32MX775F512L-80V/BG suits USB-OTG field peripherals such as data loggers, portable instruments, and configuration tools, because the on-chip USB-OTG full-speed controller supports both host and device modes without an external PHY. The 512 KB Flash allows the full USB stack plus vendor-class firmware to coexist on-chip, and 80 MHz MIPS32 throughput handles bulk transfers without CPU saturation. The 121-TFBGA keeps the device compact inside handheld enclosures, and the 2.3V to 3.6V supply is compatible with single-cell Li-ion plus boost regulators common in portable designs.
Empfohlen
Medical Patient Monitor
The PIC32MX775F512L-80V/BG fits medical patient-monitoring peripherals where low noise, deterministic timing, and rich connectivity matter. The 16-channel 10-bit ADC at 1 Msps captures multiple physiological signals simultaneously, while DMA offload data movement so the 80 MHz core can run display and Ethernet housekeeping. 512 KB Flash supports USB-OTG or Ethernet connectivity to a central monitor, and the -40C to +105C range covers typical clinical use. Designers must still validate IEC 60601-1 compliance of the complete medical device; the PIC32 alone does not provide a regulatory guarantee.
Empfohlen
Smart Sensor Hub with Ethernet
For networked sensor hubs such as building-automation controllers or industrial IoT edge nodes, the PIC32MX775F512L-80V/BG integrates the Ethernet MAC plus multiple serial interfaces required to aggregate sensor traffic. The 80 MHz core can poll I2C sensors, UART modules, and the 16-channel ADC, then push normalized data over Ethernet or USB-OTG. The 121-TFBGA footprint suits dense multi-layer PCBs, and 64 KB SRAM is adequate for packet buffers without external memory. Pairing the part with an external PHY plus RJ45 magnetics yields a full industrial sensor hub in a small BOM.
Empfohlen
Industrial Data Acquisition Front End
The PIC32MX775F512L-80V/BG serves industrial data-acquisition front ends because the 16-channel 10-bit ADC plus DMA can stream analog samples to on-chip buffers for local processing or upload via Ethernet. 80 MHz MIPS32 throughput runs the ADC sample loop plus TCP/IP stack concurrently without DMA overruns. The 512 KB Flash fits the Microchip Harmony framework plus custom DSP code for predictive maintenance analytics. The 121-TFBGA is dense enough to place behind 16-pin terminal blocks, and the -40C to +105C range handles factory floor environments where temperature swings are common.

Wichtigste Unterscheidungsmerkmale
- Integrated 10/100 Ethernet MAC plus dual CAN plus USB-OTG in one die (vs. PIC32MX575F512LT-80V/PF)
- Parallel master port for external memory expansion (vs. PIC32MX675F512L-80V/BG)
- Same 121-TFBGA footprint across PIC32MX775 and PIC32MX795 (vs. PIC32MX795F512L-80V/BG)
Designhinweise
The PIC32MX775F512L-80V/BG requires a clean 3.3V supply; place a 10 uF bulk capacitor plus 0.1 uF decoupling on every VDD ball pair to suppress transient current spikes during 80 MHz core and DMA activity. The analog AVDD rail that feeds the 10-bit ADC must be filtered with a ferrite bead and 10 uF + 0.1 uF decoupling to preserve ADC linearity below 1 LSB. Use Microchip's PIC32MX5/6/7 family reference manual section on power-supply sequencing to avoid latch-up at cold-start.
The 121-TFBGA (10x10 mm, 0.8 mm pitch) demands a 4-layer or 6-layer PCB with microvia technology for fan-out. Route the Ethernet MII/RMII signals with controlled impedance of 50 ohm single-ended and match trace lengths within 50 mil to avoid timing violations on the 25 MHz MII clock. Place the external PHY within 50 mm of the MAC balls and keep the clock trace shorter than the data traces.
At 80 MHz core speed with full Ethernet, USB, and dual CAN activity, the PIC32MX775F512L-80V/BG typically dissipates around 250 to 350 mW. The 121-TFBGA package has a junction-to-ambient thermal resistance of approximately 30 C/W on a 4-layer JEDEC test board, so junction temperature rise stays below 12 C above ambient. For sealed enclosures with no airflow, validate the thermal budget with a thermocouple on the BGA center ball.
Do not omit the external 8 MHz or 12 MHz primary crystal - the internal RC is too inaccurate for USB-OTG and Ethernet PHY clocking. Confirm configuration bits (DEVCFG) set the proper oscillator mode and disable the JTAG pins that may collide with PMP or I/O usage. When migrating from PIC32MX575 or -675 silicon, double-check that the parallel master port ball assignments match the package diagram.
