PIC18LF4480-I/ML - 8-bit MCU 16KB Flash ECAN 44-QFN | Microchip
MPN: PIC18LF4480-I/ML ✓ Hoạt độngPIC18LF4480-I/ML Tóm tắt
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, integrating a CPU core, program and data memory, digital I/O, and a set of on-chip peripherals such as timers, ADC, and communication controllers. Within the PIC taxonomy it sits as PIC18 -> 8-bit MCU -> microcontroller -> embedded IC -> semiconductor. The PIC18LF4480 belongs to the PIC18F4480 family, which was designed to bring cost-effective ECAN connectivity to industrial and automotive CAN nodes while keeping the developer-friendly PIC18 instruction set.
Key features include 16 KB Flash program memory with self-programmability, 768 bytes SRAM, 256 bytes EEPROM, an Enhanced CAN module supporting CAN 2.0B, a 10-bit ADC with up to 11 channels, two Enhanced USART modules, one MSSP (SPI/I2C) module, and nanoWatt power-saving modes that drop Iq to below 1 uA in sleep. The part supports an internal 8 MHz oscillator and an external clock up to 40 MHz, yielding 10 MIPS execution.
Typical applications include CAN nodes on the CAN bus, automotive CAN nodes with body/comfort/chassis networking, industrial CAN nodes in PLCs, sensor and actuator networks using ECAN. The wide operating voltage and industrial temperature grade (-40C to +85C) also suit process-control and building-automation CAN nodes.
When designing with this device, ensure your programmer/debugger supports the ICSP interface and that you budget for the 44-QFN thermal pad soldering to the PCB ground plane for proper heat sinking and electrical reference.

Ứng dụng tiêu biểu
PIC18LF4480-I/ML phù hợp cho 6 Áp dụngs: Industrial CAN Node, Automotive Body Electronics, Building Automation Sensor Network, Process Control and Instrumentation, Medical Device CAN Interface, Industrial Sensor and Actuator Networks.
Industrial CAN Node
The PIC18LF4480-I/ML is a classic choice for industrial CAN nodes on a CAN bus, where its integrated Enhanced CAN module implements CAN 2.0B active protocol with standard and extended identifiers. With 16 KB Flash for application logic, 768 bytes of RAM for protocol buffers, and 36 I/O for sensor/actuator interfacing, the device handles a single CAN node with adequate headroom. Operate from 3.3 V to keep noise margins clean on long CAN trunks.
Được đề xuất
Automotive Body Electronics
For automotive CAN nodes in body and comfort domains, the PIC18LF4480-I/ML offers ECAN connectivity, 10-bit ADC for sensor reading, and industrial -40 C to +85 C temperature range. Use it to drive seat controllers, HVAC blend doors, mirror modules, and lighting controllers where a small 44-QFN footprint saves PCB space. For under-hood or safety-critical systems, migrate to the AEC-Q100 qualified variants.
Được đề xuất
Building Automation Sensor Network
In building automation CAN nodes (HVAC, lighting, access control), the PIC18LF4480-I/ML supports wide-Vdd operation down to 2.0 V, enabling battery-backed sensor nodes that wake on CAN traffic. The 16 KB Flash stores protocol stacks (CANopen, DeviceNet slave) plus application code, and 36 I/O handle keypads, displays, and relays. nanoWatt sleep modes drop Iq to <1 uA for energy-harvested nodes.
Được đề xuất
Process Control and Instrumentation
For process control and instrumentation CAN nodes, the PIC18LF4480-I/ML brings deterministic 10 MIPS performance, a 10-bit ADC with up to 11 channels, and ECAN for backplane networking in PLC racks. Industrial temperature grade and wide-Vdd tolerance handle 24V industrial bus systems with simple linear regulation. The 44-QFN exposed pad aids thermal dissipation in enclosed cabinets.
Được đề xuất
Medical Device CAN Interface
In medical device CAN nodes (patient monitors, infusion pumps, lab analyzers), the PIC18LF4480-I/ML offers a reliable 8-bit core for sensor data acquisition with ECAN backhaul to a central station. Its wide-Vdd range simplifies battery-management designs, while the 10-bit ADC is sufficient for vital-sign analog front-ends. For higher-performance signal paths, pair with external 16-bit ADCs over the MSSP SPI port.
Được đề xuất
Industrial Sensor and Actuator Networks
The PIC18LF4480-I/ML anchors distributed CAN nodes in industrial sensor and actuator networks, where each node reads local sensors via the 10-bit ADC, drives actuators via PWM/CCP, and reports over ECAN. With 36 I/O and four 16-bit timers, a single MCU can multiplex multiple sensing channels. The exposed-pad QFN package keeps the board footprint under 7x7 mm.

Bảo phân biệt quan trọng
- Wide-Vdd operation down to 2.0 V vs 4.2 V on F variant (vsPIC18F4480-I/ML)
- Same 44-QFN footprint across the entire LF/F 4480/4580 family (vsPIC18LF4580-I/ML)
- Industrial temperature grade standard (no AEC-Q100) (vsPIC18F4580-I/ML)
Ghi chú thiết kế
The 44-pin QFN (ML) package has an exposed thermal pad (pin 45) that MUST be soldered to the PCB ground plane for both thermal dissipation and electrical reference. Use an array of thermal vias under the pad to conduct heat into inner copper layers. Inadequate soldering will cause erratic operation, overheating, and reduced ADC accuracy due to ground bounce.
Decouple every Vdd/Vss pair (pins 10/9, 20/19, 30/29, 40/39) with a 100 nF ceramic capacitor placed within 3 mm of the pin. Add a single 10 uF bulk tantalum or ceramic capacitor near the MCU to handle peak current transients when the ECAN module and timers switch simultaneously. The 'LF' variant operates down to 2.0 V but still requires stable Vdd for ADC accuracy.
Do not confuse the PIC18LF4480 (wide-Vdd 2.0-5.5 V) with the PIC18F4480 (4.2-5.5 V) - using the F variant on a 3.3 V rail will cause undefined behavior. Also verify that your ICSP programmer (PICkit 3, MPLAB ICD 4) is configured for the correct Vdd; the 'LF' part needs the low-voltage programming entry sequence enabled in the configuration bits.
Keep the CANRX (RE0/RA5 alt) and CANTX (RE1/RA5 alt) traces short and route them away from switching converter nodes. Use a 120-ohm termination resistor at each end of the CAN bus and place the MCP2551 transceiver within 20 mm of the MCU. Implement a TVS diode (e.g., SMAJ24CA) on the bus for transient protection in industrial environments.
