PIC18F45K80T-I/PT 概要
Key features include a 64MHz internal oscillator, 35 digital I/O pins, 3.6KB of SRAM data memory, 1KB of EEPROM, a 12-bit ADC with Charge Time Measurement Unit (CTMU), and an operating voltage range of 1.8V to 5.5V. The device executes instructions at 16 MIPS (Million Instructions Per Second) under typical conditions.
The PIC18F45K80 belongs to Microchip's PIC18 XLP 18K family, which is a subfamily of 8-bit microcontrollers within the broader PIC microcontroller taxonomy (PIC microcontroller -> MCU -> microprocessor -> semiconductor). The XLP designation indicates nanoWatt technology with sleep currents measured in nanoamps, making this family well-suited to battery-powered and energy-harvesting designs. The integrated ECAN module supports CAN 2.0B with six programmable receive/transmit buffers and three dedicated transmit buffers, eliminating the need for an external CAN controller in automotive and industrial networked applications.
Typical applications include automotive body and chassis ECAN nodes, building climate and elevator controllers, industrial sensor nodes, and battery-powered remote monitoring with CAN connectivity. The 1.8V minimum supply voltage allows operation directly from a single lithium cell across most of its discharge curve, while 5.5V tolerance supports industrial 5V rails.
Designers should note that the PIC18F45K80T-I/PT is the tape-and-reel (T) and industrial temperature (-I/-40C to +85C) variant. Pin-compatible family members with different flash densities, temperature grades, and packaging options are available for cost optimization. The microcontroller requires MPLAB X IDE and a compatible programmer such as PICkit or ICD for firmware development.

主な用途
PIC18F45K80T-I/PT の用途: 6 件s: Automotive ECAN Body Control Module, Building Automation HVAC Controller, Industrial Elevator Control, Battery-Powered Remote Sensor Node, Medical Patient Monitoring Peripheral, CAN-Based Industrial Sensor Hub.
Automotive ECAN Body Control Module
The PIC18F45K80T-I/PT is purpose-built for in-vehicle network nodes because it integrates an Enhanced CAN module supporting CAN 2.0B with six receive buffers and three transmit buffers, removing the need for an external CAN controller IC. At 64MHz / 16 MIPS, the part easily handles CAN message scheduling, sensor fusion at 100Hz, and the LIN-to-CAN gateway logic typical of door, seat, and mirror modules. The 1.8V-5.5V range tolerates 12V automotive rail transients when paired with a TVS clamp, and nanoWatt XLP sleep current under 100nA preserves battery life during key-off. The 44-TQFP footprint is industry-standard and direct-RC-solder-friendly for prototype build.
おすすめ
Building Automation HVAC Controller
The PIC18F45K80T-I/PT's 12-bit ADC with integrated CTMU is ideal for HVAC sensor nodes that measure temperature, humidity, and pressure with high linearity over wide operating ranges. The 35 I/O pins interface directly with relay drivers, TRIAC controllers, and 4-20mA loops without a serial expander. nanoWatt XLP lets the controller sleep at nanoamp currents between sensor reads, dramatically reducing building energy waste. The 5.5V tolerance aligns with 24V industrial HVAC control boards when used with a downstream regulator. Internal 64MHz oscillator eliminates external crystals, cutting BOM cost for high-volume commercial thermostat deployments.
おすすめ
Industrial Elevator Control
Elevator dispatch and door control demand deterministic response times and CAN bus connectivity, both of which the PIC18F45K80T-I/PT delivers through its ECAN module and 16 MIPS throughput. The 32KB Flash accommodates state-machine firmware for call logic, anti-trap algorithms, and fault logging. The industrial temperature range (-40C to +85C) handles unconditioned machine rooms, and the TQFP-44 package is rated for vibration-heavy motor rooms. The CTMU enables touch-button capacitive sensing without additional ASICs, simplifying the user panel design. Self-programmable flash supports in-field firmware updates over the service bus.
おすすめ
Battery-Powered Remote Sensor Node
Battery-powered wireless sensor nodes benefit from the PIC18F45K80T-I/PT's nanoWatt XLP technology, which achieves sub-100nA sleep current allowing years of operation from a single AA lithium cell. The 1.8V minimum VDD lets the part run directly from a nearly-discharged battery, while the 64MHz active mode wakes the part only when sensor data must be transmitted. The 12-bit ADC plus CTMU supports accurate ratiometric measurements on thermistors and resistive bridges. Integrated ECAN, while underutilized in purely wireless nodes, provides a wired commissioning interface for factory calibration without removing the device from service.
おすすめ
Medical Patient Monitoring Peripheral
For non-life-critical medical peripherals such as infusion pump displays, therapy timers, and bedside sensors, the PIC18F45K80T-I/PT provides the reliability of PIC18 silicon with integrated ECAN for connectivity to bedside monitoring hubs. The 12-bit ADC digitizes analog physiological signals with sufficient resolution for trend monitoring, while the CTMU enables accurate touch-panel sensing for caregiver input. The nanoWatt XLP sleep mode is essential for battery-backed devices that must remain operational during patient transport. Pin-compatible family members allow easy migration to the PIC18F46K80-I/PT if firmware exceeds 32KB.
おすすめ
CAN-Based Industrial Sensor Hub
Multi-sensor industrial hubs leverage the PIC18F45K80T-I/PT's 35 I/O count to interface with multiple analog and digital sensors while publishing aggregated data over ECAN to a PLC. The 64MHz speed handles the polling, averaging, and CAN frame assembly within the typical 10ms cycle time required for process control. Industrial temperature tolerance and TQFP-44 vibration-resistant package suit plant floor deployment. Self-programmable flash lets OEMs push sensor calibration updates over the same CAN bus used for process data, avoiding field service calls and reducing total cost of ownership.

設計ノート
Decouple VDD with a 100nF ceramic capacitor placed within 5mm of each VDD/VSS pair on the 44-TQFP package, plus a single bulk 10uF tantalum or ceramic at the chip's main VDD pin. For noise-sensitive ECAN nodes add a ferrite bead in series with VDD and a second 100nF decoupling cap on the analog supply (AVDD). The 1.8V minimum VDD lets the PIC18F45K80T-I/PT run directly from a single lithium cell - but ensure VDD rise time is less than the datasheet-specified maximum to guarantee a clean Power-on Reset.
Place the ICSP (In-Circuit Serial Programming) pins RB6/PGC and RB7/PGD on accessible test pads or a 2x3 0.1-inch header for in-field firmware updates. Route the ECAN TX/RX traces to the MCP2551 (or equivalent) CANH/CANL pins as a 120-ohm terminated differential pair with characteristic impedance of 120 ohms and length matching within 5mm. The 44-TQFP footprint exposes the die pad as GND; solder it to a large copper pour for thermal dissipation and ground integrity.
The PIC18F45K80T-I/PT's -I temperature grade is -40C to +85C; do not specify this part for underhood or industrial furnace environments - use the -E (-40C to +125C) or -H (-40C to +150C) variants instead. The internal oscillator is factory-trimmed but can drift up to 5% across temperature; for CAN timing-critical applications use an external 16MHz or 20MHz crystal with the HS-PLL configuration. Avoid driving ECAN with software bit-banging - always use the dedicated ECAN peripheral to ensure CAN 2.0B timing compliance.
