PIC32MX775F256LT-80V/BG Обзор

The Microchip Technology PIC32MX775F256LT-80V/BG is a 32-bit MIPS32 M4K microcontroller operating at up to 80 MHz, integrating 256 KB of Flash program memory and 64 KB of SRAM in a 121-pin TFBGA (10x10 mm) surface-mount package. It features 10/100 Mbit Ethernet MAC, USB-OTG, two CAN modules, and up to 105 DMIPS of processing performance for connected-embedded designs.

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 such as timers, communication interfaces, and analog blocks. The PIC32MX family belongs to the broader 32-bit MCU taxonomy: 32-bit microcontroller -> MIPS32 M4K core -> Microchip PIC32 -> Microchip Connectivity Line, sitting under the wider category of microcontrollers (semiconductor -> IC -> microcontroller). The '5/6/7' series specifically targets connected-embedded applications with on-chip Ethernet, USB, and CAN.

Key features of the PIC32MX775F256LT-80V/BG include: 256 KB Flash (256K x 8) for code storage, 64 KB SRAM for runtime data, 80 MHz maximum operating frequency delivering 105 DMIPS, integrated 10/100 Ethernet MAC with MII/RMII interface, USB 2.0 Full-Speed OTG controller, two independent CAN 2.0B modules, sixteen 10-bit ADC inputs, five 16-bit timers/counters, and a wide operating voltage of 2.3 V to 3.6 V. The 'T' suffix indicates tape-and-reel packaging, 'V' denotes the -40C to +105C industrial-grade temperature range, and 'BG' identifies the 121-pin TFBGA package.

Architecturally, the device uses a 5-stage pipelined MIPS32 M4K core with hardware multiply/divide, separate program Flash bus and SRAM bus (Harvard architecture), and a peripheral bus that supports DMA for high-throughput Ethernet and USB transfers. Code execution is in-place from Flash via an instruction cache, allowing zero-wait-state performance at 80 MHz.

Typical applications include industrial Ethernet gateways, USB-OTG device controllers, CAN-based automotive body controllers, point-of-sale terminals, and connected medical devices. The integrated triple-connectivity (Ethernet + USB + CAN) makes the part especially well suited for protocol-bridging nodes that must translate between factory, automotive, and IT networks.

When designing with this part, pay attention to the 121-ball TFBGA layout (0.8 mm pitch): it requires via-in-pad PCB fabrication and 4-layer routing for clean Ethernet signal integrity. Also confirm the 'V' temperature grade matches your end-environment, and use MPLAB Harmony or MPLAB XC32 for firmware development with the integrated peripheral libraries.

Типичное применение

PIC32MX775F256LT-80V/BG подходит для 6 применениеs: Industrial Ethernet Gateway, USB-OTG Device/Host Controller, CAN-based Automotive Body Controller, Point-of-Sale (POS) Terminal, Connected Medical Device, Industrial Protocol Bridge (CAN-USB-Ethernet).

🏭

Industrial Ethernet Gateway

The PIC32MX775F256LT-80V/BG is well suited for industrial Ethernet gateways because its integrated 10/100 Mbit MAC with MII/RMII interfaces allows direct connection to a PHY (such as Microchip KSZ8041) without an external MAC bridge. The 80 MHz MIPS32 M4K core delivers 105 DMIPS, sufficient to run an embedded TCP/IP stack (e.g., Microchip Harmony TCP/IP) while maintaining wire-speed packet forwarding. The 256 KB Flash holds the full TCP/IP + application stack, and 64 KB SRAM buffers Ethernet frames during peak load. The dual CAN modules allow the gateway to bridge industrial CANopen or DeviceNet segments to an Ethernet SCADA network. Operating voltage of 2.3 V to 3.6 V supports 3.3 V industrial rails, and the -40C to +105C industrial grade handles factory-floor environments.

🔌

USB-OTG Device/Host Controller

The PIC32MX775F256LT-80V/BG is ideal for USB-OTG device/host controllers because it integrates a USB 2.0 Full-Speed OTG controller with on-chip transceiver, eliminating the need for an external PHY. At 80 MHz, the M4K core runs the USB stack plus composite-device class drivers (CDC, HID, MSD) with DMA on the peripheral bus minimizing interrupt overhead. The 256 KB Flash accommodates dual-role USB stacks and vendor class firmware, while 64 KB SRAM handles USB endpoint buffers and protocol state. USB-OTG Session Request Protocol (SRP) and Host Negotiation Protocol (HNP) are supported in hardware, enabling portable USB devices that can act as either host or peripheral. Industrial temperature grade -40C to +105C allows use in factory diagnostic tools and outdoor instrumentation.

🚗

CAN-based Automotive Body Controller

The PIC32MX775F256LT-80V/BG fits CAN-based automotive body controllers because it integrates two independent CAN 2.0B controllers with hardware acceptance filters, supporting body-electronics networks (window, mirror, lighting, HVAC actuators) that often require multiple CAN channels. The 80 MHz core provides the processing headroom for CANopen, J1939, or OBD-II stack parsing at full bus load (1 Mbit/s). The 256 KB Flash and 64 KB SRAM are sized for typical body-controller firmware plus a CAN bootloader for field updates. The 121-ball TFBGA package, while not automotive-Q100 qualified, is acceptable for non-safety automotive body ECUs in non-AEC-Q100 applications; for safety-critical ECUs, choose a Q100-qualified variant. Operating voltage 2.3 V to 3.6 V tolerates automotive cranking transients when paired with a proper voltage regulator.

🖥️

Point-of-Sale (POS) Terminal

The PIC32MX775F256LT-80V/BG suits point-of-sale terminals because its triple connectivity (Ethernet + USB + dual CAN) allows a single chip to drive a 10/100 LAN uplink, USB barcode scanner/PIN pad/thermal printer peripherals, and CAN-based fiscal cash-drawer or scale interfaces. The 80 MHz MIPS32 M4K core delivers sufficient processing for transaction processing, encryption helpers, and display refresh, while the 256 KB Flash holds the secure payment firmware and TLS library. The 64 KB SRAM supports transaction buffer storage and TLS session state. Operating voltage 2.3 V to 3.6 V and industrial temperature range -40C to +105C cover retail environments. The 121-ball TFBGA package (10x10 mm) keeps the BOM small for compact countertop terminals.

💊

Connected Medical Device

The PIC32MX775F256LT-80V/BG is a strong fit for connected medical devices such as patient monitors, infusion pumps, and diagnostic instruments that require Ethernet for EMR connectivity, USB for service/charging ports, and CAN for internal sensor networks. The 80 MHz MIPS32 M4K core delivers 105 DMIPS, supporting real-time signal processing for vital-sign algorithms and TCP/IP TLS connections for HIPAA-compliant data upload. The 256 KB Flash and 64 KB SRAM hold a real-time OS kernel, drivers, and application firmware. The industrial temperature range -40C to +105C supports clinical environments including operating rooms and cold-storage supply areas. The integrated 10-bit ADC with 16 channels handles direct sensor interfaces (temperature, pressure, SpO2 analog front-ends) without an external ADC.

🌐

Industrial Protocol Bridge (CAN-USB-Ethernet)

The PIC32MX775F256LT-80V/BG is purpose-built for industrial protocol-bridge nodes that translate between CAN fieldbus, USB service ports, and Ethernet plant networks. The two CAN controllers accept incoming CAN 2.0B frames, the 80 MHz core parses and reformats them, and either the Ethernet MAC streams them as Modbus-TCP packets or the USB-OTG port exposes them to a service technician's laptop. The 256 KB Flash holds the protocol-conversion firmware plus web-based management UI; 64 KB SRAM handles concurrent CAN, USB, and Ethernet packet buffers. The wide operating voltage 2.3 V to 3.6 V and -40C to +105C industrial temperature range cover factory cabinet environments. The integrated 10-bit ADC supports bridge diagnostics (rail voltage, board temperature) without extra silicon.

The PIC32MX575 has 512 KB Flash vs 256 KB on the PIC32MX775, but lacks the connectivity peripherals. Choose PIC32MX775 when you need Ethernet+CAN+USB on a single chip; choose PIC32MX575 for USB-only designs requiring larger Flash.
When should I choose PIC32MX775F256LT-80V/BG over PIC32MX764F128LT-I/BG?
Choose the PIC32MX775F256LT-80V/BG when your design requires dual CAN + Ethernet + USB triple connectivity in a single chip, plus 256 KB Flash. Choose the PIC32MX764F128LT-I/BG when you need Ethernet + USB without CAN, and only 128 KB Flash is sufficient. Both share the 121-pin TFBGA 'BG' package, so PCB footprint is interchangeable if you re-spin later.
Is the PIC32MX775F256LT-80V/BG suitable for industrial automation?
Yes, the PIC32MX775F256LT-80V/BG is suitable for industrial automation, with -40C to +105C industrial temperature range, integrated CAN for fieldbus and industrial protocols, 10/100 Ethernet for SCADA/Modbus-TCP connectivity, and 80 MHz CPU performance for control loops. The 256 KB Flash and 64 KB SRAM handle typical PLC, HMI, and protocol-bridge firmware. The 121-ball TFBGA package requires a 4-layer PCB with via-in-pad, which is standard in industrial designs.
What is the best drop-in replacement for PIC32MX775F256LT-80V/BG?
The best drop-in replacement for PIC32MX775F256LT-80V/BG is the PIC32MX775F256L-80V/BG (tray packaging) - identical silicon die, same 121-pin TFBGA 'BG' package, same 80 MHz speed grade, same 256 KB Flash + 64 KB SRAM. The only difference is packaging format (Tape & Reel 'T' suffix vs Tray). All peripherals (Ethernet, USB-OTG, dual CAN) match exactly, making it a true pin-compatible drop-in.
What is the best STM32 or NXP equivalent for PIC32MX775F256LT-80V/BG?
There is no direct cross-brand drop-in equivalent for the PIC32MX775F256LT-80V/BG with exact same-package + pin-compatibility, because the 121-pin TFBGA layout is Microchip-specific. However, parametric equivalents from STMicroelectronics (STM32F407VG in LQFP-100 with Ethernet+USB but no CAN2) or NXP (LPC1778FBD208 in LQFP-208 with Ethernet+USB+CAN) offer similar functionality but require a PCB rework. The PIC32 family remains the lowest-effort replacement path.

Руководство по выбору

Choose the PIC32MX775F256LT-80V/BG when your design needs Ethernet + USB + dual CAN triple connectivity on a single chip with -40C to +105C industrial temperature range, in a 121-ball TFBGA package - the canonical choice for industrial Ethernet gateways, automotive body controllers, and CAN-USB-Ethernet protocol bridges. Choose the PIC32MX775F256L-80V/BG if you need the same silicon but prefer tray packaging for hand-prototype or low-volume assembly. Choose the PIC32MX775F256LT-80I/BG if your ambient temperature stays below 85C and you want slightly faster delivery at lower cost. Choose the PIC32MX575F512LT-80I/BG if you only need USB (no Ethernet or CAN) and want 512 KB Flash. Choose the PIC32MX764F128LT-I/BG if 128 KB Flash is enough and CAN is not required. All five parts share the same 121-pin TFBGA 'BG' footprint, enabling PCB layout reuse across variants.

Заметки по проектированию

The 121-ball TFBGA package has 0.8 mm ball pitch, which requires via-in-pad PCB fabrication to route inner balls out without dog-bone traces. Use a 4-layer minimum stackup with a dedicated ground plane directly under the BGA to control impedance for the 50 MHz RMII Ethernet signals. Decoupling: place 100 nF X7R 0402 capacitors on every VDD ball pair (B1/B2 and adjacent), plus a 4.7 uF bulk cap within 5 mm of the package. Route USB D+/D- as a 90 ohm differential pair with length matching within 150 mil, and route Ethernet MII/RMII pairs with 50 ohm single-ended impedance.

Estimate: at 80 MHz with full Ethernet+USB+CAN activity, the core draws approximately 70 mA from VDD at 3.3 V, yielding ~230 mW of digital power dissipation. The MCU also draws ~25 mA from AVDD for the ADC and PHY biasing. Total supply current is ~95 mA. Use a low-noise LDO (e.g., MCP1700) for the analog AVDD rail to avoid coupling switching noise into ADC measurements; the digital VDD can use a switching regulator for efficiency. Add a 10 uF + 100 nF decoupling pair at every supply ball grouping.

The 121-ball TFBGA has a thermal resistance of approximately 32 C/W (theta_JA) on a 4-layer JEDEC test board. At the estimated 230 mW worst-case dissipation, the junction rises ~7C above ambient - well within the -40C to +105C industrial temperature range. No external heatsink is required for normal operation. For designs with the chip located near other heat sources (e.g., power regulators), provide adequate copper pours on top and inner layers tied to ground for additional heat spreading.

Do not leave the JTAG/TRACE pins floating - tie TRST low through a 10 kohm resistor to ground for normal operation, or to VDD only when JTAG is in use. The two CAN modules share clocking infrastructure - if you use only one CAN, tie the unused TX pin to ground via 10 kohm and leave RX unconnected per Microchip errata. For USB-OTG operation, the VBUS ball must be connected through a voltage divider (100k/20k) to sense USB host voltage; do not tie directly to VDD.

The 10/100 Ethernet MAC requires an external PHY (e.g., KSZ8041 for MII/RMII). For 100 Mbit operation, the REFCLK signal is 50 MHz and must be routed with controlled impedance; place a 33 ohm series termination resistor at the MAC TX pins if trace length exceeds 25 mm. The CAN bus signals (C1TX, C1RX) should be routed as a differential pair with 120 ohm characteristic impedance, with the bus termination resistor (120 ohm) placed only at the physical ends of the bus, not at intermediate nodes.
