PIC18LF46K80T-I/PT Übersicht
An 8-bit PIC microcontroller is a RISC-architecture MCU built around a 16-bit instruction word, providing deterministic execution timing and rich peripheral integration for cost-sensitive embedded designs. PIC18LF devices sit at the top of the 8-bit PIC family, adding large linear RAM, hardware ECAN/USB stacks, and nanoWatt XLP™ sleep modes that push active current down to the single-digit mA range and sleep current to the sub-microamp range. Within the broader semiconductor hierarchy, PIC MCUs belong to the microcontroller family, which itself sits inside the embedded system category of integrated circuits.
Key features include a 12-bit A/D converter with up to 12 channels, a CTMU (Charge Time Measurement Unit) for capacitive touch sensing, four 16-bit timers, two CCP/ECCP modules, two MSSP (I²C/SPI) ports, two ECAN modules, two comparators, and 35 general-purpose I/O pins. The device supports LIN, SPI, I²C, and CAN connectivity, plus a 4 KB EEPROM for non-volatile data storage. The nanoWatt XLP™ feature delivers an ultra-low standby current profile for energy-harvesting and IoT battery designs.
Architecturally, the PIC18LF46K80 uses a Harvard-style RISC core with hardware multiply and a 31-level stack, providing predictable interrupt latency and deterministic real-time control. Its ECAN™ peripheral supports CAN 2.0B with acceptance filters, making it a strong fit for automotive body and industrial networks. The integrated CTMU simplifies touch-button and capacitive-proximity interfaces without an external analogue front end.
Typical applications include CAN node endpoints, automotive body controllers, sensor nodes, industrial control panels, and low-power IoT endpoints. The wide -40 °C to +85 °C industrial temperature range, combined with the low-voltage operating window, makes this part a strong fit for any 3.3V system requiring robust connectivity and ultra-low standby power.
When designing with this device, ensure the supply stays within 1.8V to 3.6V (LF variant) and that the ECAN bus is terminated with 120 Ω at each end. For sleep-mode current to reach the datasheet minimum, the MCLR pull-up and unused I/O lines must be configured to avoid parasitic current paths.

Typische Anwendungen
PIC18LF46K80T-I/PT ist geeignet für 6 Anwendungs: Automotive CAN Node, Industrial Sensor Node, Capacitive Touch Interface, Battery-Powered IoT Endpoint, Home Appliance Control Board, Portable Medical Monitor.
Automotive CAN Node
The PIC18LF46K80T-I/PT fits automotive CAN nodes because its two integrated ECAN™ modules implement CAN 2.0B with acceptance filters, eliminating the need for an external CAN controller. With 64 KB flash, 3.6 KB RAM, and 1.8V–3.6V supply, it handles OBD-II firmware, J1939 stacks, and gateway tasks while staying within automotive power budgets. Pair with an MCP2551 or MCP2562 CAN transceiver; the LF variant operates on a 3.3V rail common in body-electronics modules.
Empfohlen
Industrial Sensor Node
In industrial sensor nodes the PIC18LF46K80T-I/PT serves as the local controller and protocol translator. Its 12-bit ADC with up to 12 channels handles multi-sensor scanning (temperature, pressure, current) while the ECAN module reports back to a PLC. The 64 MHz CPU executes J1939 or CANopen stacks in real time. The industrial -40 °C to +85 °C temperature range and robust PIC18 XLP peripheral set suit factory-floor deployments.
Empfohlen
Capacitive Touch Interface
The PIC18LF46K80T-I/PT is well suited for capacitive touch interfaces thanks to the integrated CTMU (Charge Time Measurement Unit), which measures capacitance changes on a button or slider pad without an external analogue front end. With 64 KB flash and 35 GPIO, the same MCU runs the touch firmware, drives the LCD, and communicates via UART to a host controller. The 12-bit ADC supports proximity-sensor overlays and LED current sense.
Empfohlen
Battery-Powered IoT Endpoint
The PIC18LF46K80T-I/PT fits coin-cell and 2xAA IoT endpoints because the nanoWatt XLP™ sleep current drops to sub-microamp levels, and the 1.8V–3.6V supply accepts a CR2032 coin cell directly. With 64 KB flash and 3.6 KB RAM, the part handles BLE/Zigbee co-processor command parsing, sensor aggregation, and ECAN / LIN bus duty cycling. The integrated 12-bit ADC reads battery voltage for accurate SoC reporting.
Empfohlen
Home Appliance Control Board
White-goods and HVAC controllers benefit from the PIC18LF46K80T-I/PT's LIN bus connectivity for sensor/actuator networking, plus the ECAN port for higher-speed backbone links to the main board. The 35 GPIO drive relays, TRIACs, and status LEDs directly, and the 12-bit ADC reads thermistors and pressure transducers. The industrial temperature range covers under-cabinet and outdoor HVAC environments.
Empfohlen
Portable Medical Monitor
Portable medical devices such as pulse oximeters and glucose meters leverage the PIC18LF46K80T-I/PT's low-voltage operation, low sleep current, and 12-bit ADC for accurate sensor readout. The 64 KB flash stores reference curves and calibration tables, while the ECAN port enables secure wired connectivity to hospital networks. The wide operating temperature range and the LF variant's 1.8V minimum suit lithium-primary powered designs.

Wichtigste Unterscheidungsmerkmale
- Integrated ECAN module (CAN 2.0B) eliminates external CAN controller (vs. PIC18LF46K40-I/PT)
- Two ECAN modules enable CAN gateway or dual-bus architectures (vs. PIC18LF26K80T-I/SO)
- CTMU peripheral simplifies capacitive touch firmware (vs. PIC18LF46J11-I/ML)
Designhinweise
For nanoWatt XLP™ sleep current to reach the datasheet minimum (sub-1 µA), unused peripherals must be disabled in the PMDx register and unused I/O configured as outputs driving low. The MCLR pull-up should be implemented as a 100 kΩ resistor or omitted in sleep-only designs to prevent parasitic current paths through the input protection diodes.
Keep the ECAN TX/RX traces short and matched to within 5 mm to comply with CAN 2.0B bus timing at 1 Mbps. Place a 120 Ω termination resistor at each end of the bus only, not on every node. The 44-pin TQFP-44 (10x10) package benefits from a continuous ground plane beneath the device to provide thermal dissipation and a low-impedance return path for ECAN and MSSP signals.
Do not exceed 3.6V VDD on the LF variant - operation above the absolute-maximum supply voltage will damage the part. If a 5V supply is unavoidable, choose the PIC18F46K80T-I/PT sibling instead. For ECAN loop-back tests, remember to put the microcontroller into Loopback mode by setting the CANCTRL.REQOP bits before connecting to an active bus, otherwise it will interfere with other nodes.
Estimated: At maximum 64 MHz CPU clock with all peripherals active, the PIC18LF46K80T-I/PT draws approximately 15 mA from a 3.3V supply, dissipating about 50 mW. The TQFP-44 (10x10) package has a typical theta_JA around 50 °C/W, giving a junction temperature rise of only 2.5 °C above ambient - no heatsink is required. Thermal management is dominated by I/O current, not core power.
