PIC18F26K80-H/SS Visão geral
What is an 8-bit microcontroller with integrated CAN? It is a single-chip processor that combines a CPU, memory, peripherals, and a CAN bus interface in one package, sitting in the embedded hierarchy between a bare microprocessor and a complete system-on-module. The ECAN peripheral (enhanced CAN) implements the ISO 11898 CAN 2.0B protocol with hardware acceptance filters, allowing a microcontroller class device to communicate reliably on automotive and industrial CAN buses without an external controller chip. Adding nanoWatt XLP technology to this mix places the device in the low-power MCU category.
Key features include a 12-bit ADC with up to 11 channels, a CTMU (Charge Time Measurement Unit) for capacitive touch and time-of-flight sensing, multiple timers, an enhanced addressable USART, SPI and I2C peripherals, and the nanoWatt XLP idle/sleep current well below typical microamps. The 28-SSOP package keeps the footprint compact for dense PCB designs while exposing the full peripheral set of the larger 40/44/64-pin family members. The device is built around a modified Harvard architecture with separate program and data buses, giving deterministic single-cycle execution for most instructions.
Typical applications include automotive body and chassis ECAN nodes, industrial building-automation controllers, elevator control panels, capacitive-touch user interfaces, sensor hubs, and battery-powered remote nodes. The wide 1.8V-5.5V supply range allows direct operation from a single Li-ion cell or a regulated 3.3V/5V rail, simplifying power-tree design. AEC-Q100-grade thermal performance and ECAN make it a strong candidate for in-vehicle networking such as door modules, lighting controllers and HVAC nodes. When designing with this MCU, allocate an unused pair of I/O lines to the ECAN TX/RX pins and provide a CAN transceiver (such as MCP2551 or MCP2562) between the MCU and the bus; do not connect the MCU directly to a CAN bus without galvanic isolation considerations.

Aplicações típicas
PIC18F26K80-H/SS é adequado para 6 aplicaçãos: Automotive Body and Chassis ECAN Node, Industrial Building-Automation Controller, Battery-Powered Sensor Hub, Capacitive Touch User Interface, Elevator / Lift Control Panel, Automotive Lighting and HVAC Node.
Automotive Body and Chassis ECAN Node
The PIC18F26K80-H/SS is purpose-built for automotive ECAN nodes that need an integrated ISO 11898 CAN 2.0B controller without an external chip. The integrated ECAN peripheral has hardware acceptance filters and dedicated transmit/receive buffers, so a single MCU can serve as a door-module, seat-controller, lighting-driver or HVAC-node endpoint with reduced PCB area. The AEC-Q100 high-temperature -40 to +150C grade tolerates under-hood thermal stress and the wide 1.8-5.5V supply rides through automotive cranking transients. Recommend companion MPN MCP2562 (CAN transceiver) and PIC18F46K80 when migrating to a higher-pin-count design.
Recomendado
Industrial Building-Automation Controller
Building-automation equipment (HVAC controllers, elevator panels, sensor hubs) benefits from the PIC18F26K80-H/SS combination of 64KB Flash for CANopen or BACnet-style protocol stacks and the 12-bit ADC for analog sensor reading. The nanoWatt XLP extreme low-power technology cuts standby current during idle polling and the wide 1.8-5.5V supply simplifies power-tree design across 3.3V and 5V subsystems. With 24 I/O pins and CTMU capacitive-touch support, the MCU can read multiple push-buttons, rotary encoders and touch sliders without extra analog-front-end chips. Recommended companion MPNs include MCP2551 (CAN transceiver) for inter-floor bus and PIC18F46K80 (higher pin-count variant) for supervisory logic.
Recomendado
Battery-Powered Sensor Hub
In distributed sensor networks powered by 3.6V Li-SOCl2 cells or two AA batteries, the PIC18F26K80-H/SS maximises battery life thanks to nanoWatt XLP technology that drops standby current to a few microamps. The 1.8-5.5V supply works directly from a single Li-ion cell or a regulated 3.3V rail, removing the need for an additional boost converter. The CTMU (Charge Time Measurement Unit) enables capacitive water-level, soil-moisture or proximity sensing without dedicated front-end ICs, and the integrated 12-bit ADC reads thermistor or 4-20mA-loop signals through simple signal conditioning. Suggest MCP1700 (3.3V LDO) for supply regulation and PIC18F46K80 (40-pin variant) as next-step migration path.
Recomendado
Capacitive Touch User Interface
The PIC18F26K80-H/SS Charge Time Measurement Unit (CTMU) provides a constant-current source that, combined with the on-chip ADC, measures capacitance changes in real time to deliver up to 16 capacitive touch channels. Designers can build touch keypads, sliders, proximity sensors and rotary encoders without dedicated touch ICs, lowering BOM cost in consumer appliances and entry-level industrial HMIs. The 16 MIPS instruction throughput keeps touch-decoding responsive under multi-touch scanning, and the 64KB Flash comfortably supports bootloader plus UI firmware. Recommended companion: PIC18F46K80 (when more I/O needed) and MCP2221 (USB bridge for firmware update).
Recomendado
Elevator / Lift Control Panel
In elevator controller and lift control panel deployments the PIC18F26K80-H/SS handles multi-floor LED/LCD indicator driving while its ECAN interface participates in the cabin-to-machine-room CAN bus used for floor-call messaging and diagnostics. The 12-bit ADC reads button voltages with proper debounce filtering, the enhanced USART supports panel programming terminals, and the 64KB Flash is large enough for floor-mapping, fault-logging and CANopen remote I/O stacks. AEC-Q100 qualification and -40 to +150C tolerance ease compliance with lift-industry environmental testing. Use MCP2551 (CAN transceiver) and PIC18F46K80 (controller) in pair; PIC18F25K80 (lower flash) suits auxilliary floor-extension boards.
Recomendado
Automotive Lighting and HVAC Node
Drivers for LED headlamp controllers, rear-lamp modules and HVAC damper actuators rely on the PIC18F26K80-H/SS automotive grade -40 to +150C thermal range and on the AEC-Q100 grade qualification. The 12-bit ADC reads thermistor and current-sense inputs for thermal foldback on LED strings, while the PWM output drives power-FET gate drivers via opto or driver chips. ECAN 2.0B allows the node to participate in body-controller messages such as 'lights on' and 'door open' without an external CAN chip. Recommend companion MPN MCP2562 (CAN transceiver) and PIC18F46K80 (higher pin-count sibling); for non-automotive HVAC use PIC18F26K80-I/SS is a cost-optimised substitute.

Notas de projeto
Place decoupling capacitors close to the VDD/VSS pins: 100nF ceramic on every VDD/VSS pair and 10uF tantalum or ceramic at the supply entry. The PIC18F26K80-H/SS draws only a few microamps in sleep mode thanks to nanoWatt XLP, but its in-rush during full-speed 64MHz wake-up can momentarily exceed 30 mA on the digital rail; a large bulk cap helps prevent supply droop.
Do not connect the PIC18F26K80-H/SS CANTX/CANRX pins directly to a CAN bus - they are 5V-logic CMOS signals, not bus-level differential. Route them through an MCP2551 or MCP2562 CAN transceiver to convert to the ISO 11898 differential signals on the bus. Also ensure that MCLR (pin 1) is pulled to VDD through a 10k resistor and that PGC/PGD (RB6/RB7) remain accessible for ICSP debugging.
Route the crystal oscillator traces RA6/RA7 (when used) over a continuous ground plane and keep them short (less than 10 mm) to minimise EMI pickup. The 28-SSOP package is small (5.30 mm body width), so use 0.2 mm clearances between SSOP pads and high-voltage signals, and keep analog inputs away from PWM output traces to prevent coupling into the 12-bit ADC.
