MPN: PIC18F26K80-E/SP ✓ Hoạt độngPIC18F26K80-E/SP Tóm tắt
What is a PIC18F microcontroller? The PIC18F family is Microchip's 8-bit RISC architecture line designed for embedded control, bridging the gap between the legacy PIC16 family and the more powerful PIC24/dsPIC families. It belongs to the wider microcontroller category (MCU -> 8-bit MCU -> PIC18F -> K80 sub-family) and serves applications requiring deterministic real-time control, peripheral integration, and low-power sleep behaviour.
Key features of the PIC18F26K80-E/SP include a 12-bit ADC with up to 11 channels, a CTMU (Charge Time Measurement Unit) for capacitive touch and precise time measurement, an enhanced CAN module supporting CAN 2.0B active and passive, three analogue comparators, two ECCP/SCCP modules and multiple timer peripherals. The 'K80 family is notable for its 1.8V to 5.5V operating range and very low sleep current, enabling battery-backed applications. AEC-Q100 Grade 1 qualification makes the part suitable for under-hood and cabin automotive designs.
The PIC18F26K80-E/SP uses a 16-bit modified Harvard architecture with pipelined instruction fetch and a 31-level hardware stack. The internal oscillator is selectable from 32 kHz to 16 MHz, with PLL support to 64 MHz. nanoWatt XLP technology provides deep sleep modes down to a few hundred nanoamps, RTCC from a separate timer, and multiple idle modes.
Typical applications include CAN node ECUs, automotive body and climate control, elevator control, industrial sensor hubs, building automation, USB-to-CAN bridges, and low-power metering. The -E temperature grade supports -40C to +125C.
When designing with this MCU, observe the decoupling guideline of 0.1 uF plus bulk capacitance near VDD/AVDD pins, route the ECAN TX/RX as a differential pair with 120 ohm termination, and configure the WDT and BOR in MPLAB X projects for fail-safe bring-up.

Ứng dụng tiêu biểu
PIC18F26K80-E/SP phù hợp cho 6 Áp dụngs: Automotive Body Control Module, Elevator Control Node, Building Automation / HVAC Controller, Industrial Sensor Hub (CAN node), USB-to-CAN Bridge Adapter, Battery-Backed Metering and Wireless Sensor Node.
Automotive Body Control Module
The PIC18F26K80-E/SP fits automotive body-control nodes because its AEC-Q100 Grade 1 qualification and -40C to +125C range cover under-hood and cabin thermal stress. The integrated ECAN module serves 125 kbit/s to 1 Mbit/s CAN-FD-style traffic without an external controller, and the nanoWatt XLP sleep mode draws only nanoamps when the bus is quiet, preserving quiescent battery drain. Its 24 I/O pins are sufficient to drive low-side FET arrays for door lock, mirror and lighting loads, while three analogue comparators and a 12-bit ADC with CTMU handle window lift and rain-light sensing.
Được đề xuất
Elevator Control Node
The PIC18F26K80-E/SP is well-suited to elevator control panels and door-zone nodes thanks to its deterministic 16 MIPS core, three 16-bit timers and three ECCP modules. These peripherals drive triac-based motor control and PWM indicator rings while the CTMU measures capacitive touch buttons without an external ASIC. The 1.8V-5.5V operating window allows direct connection to a 24V->5V industrial rail, and the ECAN peripheral links the node into the elevator's distributed CAN backbone. AEC-Q100 Grade 1 screening also handles the 0 to +70C shaft environment with margin.

Building Automation / HVAC Controller
HVAC and building-automation controllers benefit from the PIC18F26K80-E/SP's nanoWatt XLP deep-sleep modes that hold less than 1 uA, allowing wireless and battery-backed room sensors to operate for years on a coin cell. The 12-bit ADC reads multiple temperature and humidity sensors, while the ECAN or UART peripheral reports to a central BMS over a CAN or RS-485 link. AEC-Q100 qualification guarantees reliability in plant-room thermal swings, and the 28-SPDIP package simplifies through-hole servicing in field-deployed thermostats and damper actuators.
Được đề xuất
Industrial Sensor Hub (CAN node)
Factory sensors with CAN output pair naturally with the PIC18F26K80-E/SP. The ECAN hardware acceptance filter offloads bus traffic from the CPU, freeing 16 MIPS for sensor fusion, while three analogue comparators detect analog thresholds directly without ADC conversion. CTMU measures small capacitance changes for proximity or level sensing, and the 1.8V-5.5V supply range accepts power from a 24V industrial backplane or a 3.3V local LDO. AEC-Q100 qualification brings long-term reliability to 24/7 factory environments.
Được đề xuất
USB-to-CAN Bridge Adapter
When paired with a USB-UART bridge, the PIC18F26K80-E/SP forms a low-cost USB-to-CAN adapter used in automotive diagnostics. The ECAN peripheral handles the bus side while UART (or a software-over-USB channel) talks to the host. Its 64KB Flash holds the device firmware and a small scripting engine, and 3.6KB RAM is enough to buffer CAN frames. The 64 MHz CPU sustains full 1 Mbit/s CAN throughput and parses UDS / OBD-II requests in real time.
Được đề xuất
Battery-Backed Metering and Wireless Sensor Node
For wireless metering and remote sensor nodes, the PIC18F26K80-E/SP brings nanoWatt XLP sleep currents in the nanoamp range, enabling multi-year operation on a single AA cell. The 12-bit ADC with internal reference achieves calibrated voltage and current measurements, while CTMU measures small capacitive changes for fuel- or water-level sensing. ECAN or UART acts as the upstream link, and the 1.8V minimum VDD keeps the node alive down to battery cut-off, maximizing usable capacity.

Ghi chú thiết kế
Place a 0.1 uF ceramic bypass capacitor within 3 mm of each VDD/VSS pair (pins 7/8 and 19/20 on the SPDIP-28) plus a single 4.7 uF to 10 uF bulk capacitor at the supply entry. The PIC18F26K80-E/SP can operate down to 1.8V but its ECAN bus levels require 3.3V or higher to meet CAN driver thresholds, so a separate LDO for the CAN transceiver rail is recommended when VDD dips during sleep.
For the ECAN bus, route CANTX and CANRX as a 100 ohm differential pair and place the MCP2562 transceiver within 25 mm of the MCU. Provide a 120 ohm termination resistor at each end of the bus, never mid-line. Keep the CAN traces away from switching regulator nodes (for example a buck converter SW node) to avoid coupling common-mode noise into the CAN receiver.
Do not configure the PIC18F26K80-E/SP for the K22/CTMU register layout; the K80 family has different SFR addresses for CTMU and CAN. Always rebuild the project with the XC8 compiler and the pic18f26k80 device family pack when migrating from PIC18F26K22 firmware. Confirm the CONFIG fuses (FOSC, BOR, WDT) match the application thermal and reset requirements.
Estimated: at a CPU utilisation of 80% with 64 MHz CPU clock and 3.3V VDD, the PIC18F26K80-E/SP draws approximately 14 mA core current. Power dissipation is roughly 46 mW, well within the SPDIP-28 thermal envelope (theta_JA ~70 C/W) and far below the 125C junction limit; no heatsink is required for typical embedded designs.
