PIC18F4480-I/PT - 8-bit 40MHz MCU 16KB Flash w/ ECAN | Microchip
MPN： PIC18F4480-I/PT ✓ 啟用中PIC18F4480-I/PT 概覽
A PIC18 microcontroller is an 8-bit Harvard-architecture MCU from Microchip's PIC18 family - the performance tier above the baseline PIC16 line, designed for high computational performance at economical cost with the addition of Enhanced Flash program memory. It belongs to the broader category of microcontrollers (MCU) -> embedded controllers -> microprocessors, and is part of Microchip's power-management-aware nanoWatt technology family that adds sleep and idle modes to reduce active current consumption.
Key specifications include: 40 MHz maximum clock speed, 16 KB Flash program memory, 768 bytes SRAM, 256 bytes EEPROM, 36 I/O pins, 11 channels of 10-bit ADC, an ECAN module, USART, MSSP (SPI/I2C) peripherals, and a 4.2 V to 5.5 V supply voltage range. The industrial -40 C to +85 C temperature range supports embedded applications in non-automotive environments.
The ECAN controller is the headline feature, implementing the CAN 2.0B active protocol with hardware acceptance filters and prioritization. Combined with the 10-bit ADC and nanoWatt sleep modes, the PIC18F4480 fits embedded industrial nodes that require deterministic serial communication alongside analog sensing. The 44-pin TQFP (PT) package exposes enough pins for full peripheral operation while remaining hand-solderable for prototypes.
Typical applications include industrial CAN nodes, sensor hubs, motor-control signal conditioning front-ends, building automation controllers, and low-power remote sensor platforms. The wide supply voltage range (4.2 V to 5.5 V) and nanoWatt sleep modes make the device usable in 5 V industrial backplanes.
When designing with this device, verify that the on-chip ECAN controller matches the CAN protocol in your network. For designs that do not need ECAN, the PIC18F4580 (32 KB Flash) or PIC18F4450 (USB) offer more memory or USB connectivity in the same TQFP-44 footprint.

典型應用
PIC18F4480-I/PT 適用於 6 應用s: Industrial CAN Node, Sensor Hub with Digital I/O, Building Automation Controller, Low-Power Remote Sensor Platform, Motor Control Signal Conditioning, Industrial User Interface Front-End.
Industrial CAN Node
The PIC18F4480-I/PT's integrated Enhanced CAN (ECAN) controller implementing CAN 2.0B active makes it ideal for industrial CAN nodes requiring deterministic serial communication with hardware acceptance filters and message prioritization. The 40 MHz core delivers 10 MIPS throughput, sufficient for processing sensor data and CAN frame payloads at 1 Mbit/s bus speeds, while the 11-channel 10-bit ADC acquires analog field-sensor inputs. Power is supplied from 4.2 V to 5.5 V industrial backplanes, and the 44-pin TQFP package exposes 36 I/O pins for status LEDs and digital I/O expansion. Designers place 0.1 uF decoupling close to each VDD pin and a 10 uF bulk capacitor on the bus rail. Compared with discrete CAN implementations, the integrated ECAN reduces BOM cost and PCB area by replacing external CAN transceivers' SPI interface glue.

Sensor Hub with Digital I/O
The PIC18F4480-I/PT's 36 digital I/O pins and 11-channel 10-bit ADC suit it for multi-sensor hub aggregation in industrial monitoring. Each ADC channel handles thermistor, pressure, or voltage sensing with successive-approximation conversion, while the ECAN module backhauls aggregated telemetry over a CAN bus to a central controller. nanoWatt sleep modes drop quiescent current below typical sensor standby levels, enabling battery-backed remote sensor platforms. The 4.2 V to 5.5 V supply range tolerates wide industrial rail variations. The -I industrial temperature suffix supports -40 C to +85 C deployment in factory floors. Designers use the MSSP peripheral for SPI-based digital sensors and the USART for RS-485 expansion, sharing 36 I/O without muxing.
推薦
Building Automation Controller
The PIC18F4480-I/PT fits building automation sub-controllers requiring BACnet or CAN-based communication, with 16 KB Flash accommodating protocol stacks plus control logic. The 40 MHz core runs 10 MIPS, sufficient for PID loops on HVAC actuators and lighting ballasts, while the 11-channel ADC reads 0-10 V or 4-20 mA analog inputs from field devices. Industrial -40 C to +85 C temperature range supports mechanical rooms and rooftop enclosures. The ECAN module integrates with BMS trunk lines, reducing the need for external protocol bridges. The 44-pin TQFP package with 36 I/O provides enough headroom for relay drivers, keypad inputs, and LED indicators. Designers typically run the part at 4 MHz from the internal oscillator to minimize EMI in noise-sensitive installations.
推薦
Low-Power Remote Sensor Platform
The PIC18F4480-I/PT's nanoWatt technology provides sleep, idle, and doze modes that reduce current consumption for battery-powered remote sensor platforms. The 256-byte EEPROM stores calibration constants across sleep cycles, and the 10-bit ADC wakes the core on threshold crossings to maximize battery life. The 4.2 V to 5.5 V supply range supports 3-cell alkaline or lithium battery packs with boost regulation. The 768-byte RAM is ample for sensor queue buffering between ECAN transmissions. The -40 C to +85 C temperature grade suits outdoor installations. Designers use the MSSP peripheral to communicate with low-power SPI sensors during wake windows, then return to sleep between measurement intervals to achieve multi-year battery life.
推薦
Motor Control Signal Conditioning
The PIC18F4480-I/PT's 10-bit ADC and 36 I/O make it suitable as a signal-conditioning front-end for small motor drives and BLDC commutation timing. The 40 MHz core executes FOC loops at switching frequencies suitable for small brushless motors up to several kHz. The ECAN module provides deterministic communication with the system controller, while USART and MSSP handle encoder feedback and gate-driver interfaces. Industrial -40 C to +85 C temperature rating supports motor enclosures. The 4.2 V to 5.5 V supply matches 5 V gate-driver rails. Designers commonly pair the device with MCP8024 BLDC gate drivers and MCP2551 CAN transceivers to build compact networked motor nodes.
推薦
Industrial User Interface Front-End
The PIC18F4480-I/PT can act as a user-interface front-end controller for industrial HMIs, keypads, and LED indicators. The 36 I/O pins drive matrix keypads up to 6x6, while the 11-channel ADC reads analog potentiometers and rotary encoders. The ECAN module backhauls user input events to the main controller over an industrial CAN bus, simplifying wiring in distributed control panels. The 4.2 V to 5.5 V supply range suits industrial 5 V rails, and the -I industrial temperature suffix supports factory floor installations. The 16 KB Flash accommodates debouncing, hold-timer, and CAN message formatting logic. Designers use the MSSP peripheral to drive SPI-based LED drivers or character displays, sharing the 36 I/O without multiplexing.

設計說明
Place a 0.1 uF ceramic decoupling capacitor close to each VDD pin (pin 10 and pin 20) and a single 10 uF tantalum or ceramic bulk capacitor on the board power rail. The PIC18F4480-I/PT draws peak transient currents during ECAN transmissions and ADC conversions; without local decoupling, supply ripple can cause ECAN bit errors and ADC reference drift. nanoWatt sleep modes drop quiescent current to single-digit microamps - useful for battery-backed remote nodes, but the wake-up latency must be accounted for in CAN message timing.
Route the CANRX and CANTX differential pair (pins 41, 42) to the external MCP2551 transceiver with matched-length, impedance-controlled traces and keep them isolated from the oscillator pins (OSC1, OSC2 - pins 43, 44). Place the crystal or resonator within 10 mm of the oscillator pins with short ground-return vias. Use a four-layer PCB with a dedicated ground plane beneath the TQFP-44 footprint to minimize EMI coupling into the 10-bit ADC analog inputs (AN0-AN5 on pins 33-38).
Configuration bits must be programmed correctly to enable the internal oscillator and disable the watchdog timer for predictable ECAN timing. The MSSP peripheral conflicts with the ECAN module on certain pin assignments - consult the datasheet pin function tables before assigning SPI or I2C functions to overlapping PORTB/PORTC pins. Do not exceed 5.5 V on any I/O; the PIC18F4480-I/PT is not 5V-tolerant on analog inputs when operating above 5.5 V VDD. Always include an ICD 5 or ICD 4 in-circuit debugger header (PGC/PGD on pins 7, 8) for firmware development.
Estimated: the PIC18F4480-I/PT dissipates approximately 200-300 mW at 40 MHz with all peripherals active at 5.0 V VDD. The 44-pin TQFP package has a thermal resistance (theta_JA) of approximately 50 C/W on a standard 4-layer JEDEC test board, yielding a junction-to-ambient temperature rise of roughly 15 C above ambient. At the upper industrial limit of +85 C ambient, junction temperature remains well below the +150 C maximum, so no heatsink is required under normal operating conditions.
