PIC18F26K80-I/SO - 64KB Flash 8-bit MCU w/ ECAN | Microchip

The Microchip Technology PIC18F26K80-I/SO is a high-performance 8-bit flash microcontroller with integrated ECAN (CAN 2.0B active) and nanoWatt XLP (eXtreme Low Power) technology, housed in a 28-pin SOIC wide-body package. It delivers 64 MHz (16 MIPS) performance with 64 KB of flash program memory, 3.6 KB of RAM, and 1 KB of EEPROM. The device operates from 1.8 V to 5.5 V, features a 12-bit ADC with up to 11 channels, and supports automotive temperature grades of -40°C to +85°C in the -I variant. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit CPU core - in this case Microchip's PIC18 RISC architecture - that integrates program memory (flash), data memory (SRAM), non-volatile EEPROM, and peripherals onto one die. The PIC18F26K80 sits in the broader hierarchy: 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. It is part of Microchip's PIC18 K-series, distinguished by integrated ECAN, XLP sleep modes, and a wide operating voltage range that supports both 3.3 V and 5 V designs. Key features include 64 KB flash (32K x 16 words), 3.6 KB RAM, 1 KB EEPROM, integrated ECAN module, a 12-bit A/D converter with up to 11 input channels, 4 hardware timers, two MSSP (SPI/I2C), two enhanced USART modules, and nanoWatt XLP sleep currents as low as 100 nA. The 12-bit ADC delivers conversion rates up to 100 ksps and supports an internal bandgap reference for ratiometric measurements. The PIC18F26K80 uses Microchip's enhanced PIC18 Harvard architecture with a 16-bit instruction word and 8-bit data path, allowing single-cycle hardware multiply and 200 ns instruction execution at 64 MHz. The ECAN module supports CAN 2.0B active with acceptance filters and masks, and the integrated CTMU (Charge Time Measurement Unit) enables touch sensing and precise time-of-flight measurements. Typical applications include industrial CAN-bus node controllers, automotive body and chassis modules, elevator control panels, building automation, sensor interfaces with analog front-ends, and low-power battery-operated sensor nodes where ECAN connectivity and nanoWatt XLP combine to enable wire-replacement topologies with extended battery life. When designing with this part, verify the SOIC-28 footprint and pinout against your PCB land pattern. For new designs, Microchip recommends the newer PIC18F26K42 family with Core Independent Peripherals unless specific ECAN migration paths are required - the K42 family uses a different oscillator and interrupt architecture and is NOT a drop-in replacement.

The Microchip PIC18F26K80-I/SP is a high-performance 8-bit CMOS flash microcontroller built on the PIC18 RISC architecture, featuring integrated ECAN, 64 KB of program Flash, 3648 bytes of RAM, and a 12-bit ADC with CTMU, packaged in a 28-pin SPDIP (SP) through-hole form factor. It executes instructions in 200 ns (16 MIPS at 64 MHz) and operates over a 1.8 V to 5.5 V wide supply range with nanoWatt XLP extreme low-power sleep modes for energy-constrained designs. An 8-bit microcontroller (MCU) is a programmable single-chip processor that integrates CPU, non-volatile program memory, volatile data memory, and peripherals on one die; it sits in the hierarchy: microcontroller -> embedded processor -> semiconductor device. The PIC18 family extends this with enhanced 16-bit instruction width, hardware multiply, and C-optimized architecture, while the K80 sub-family adds an on-board ECAN 2.0B controller, making the part suited to distributed industrial networks where automotive-grade robustness matters. Key features include 24 I/O pins, an internal oscillator selectable up to 64 MHz, three 16-bit timers, two CCP/ECCP modules, an enhanced USART, two SPI and two I2C peripherals, a 12-channel 12-bit ADC, and CTMU (Charge Time Measurement Unit) for capacitive touch and precise time-based measurements. The ECAN module is CAN 2.0B active with hardware filtering, and the nanoWatt XLP technology delivers sleep currents down to the nanoampere range, enabling battery-backed designs that wake on interrupt. Typical applications include automotive body and comfort modules (CAN nodes for window lifters, seat controllers), elevator control boards, industrial building automation (HVAC, lighting controllers), CAN-based sensor networks, and low-power metering with touch-button front panels. The wide 1.8 V-5.5 V range also lets the same firmware run directly from a single Li-ion cell or a regulated 5 V rail without a level shifter. When designing with this part, budget decoupling capacitance at each VDD/VSS pair (100 nF plus 1-10 µF bulk), and assign the ECAN TX/RX pins to PWM-capable ports only if pin remapping is not used, since CAN bus timing is sensitive to jitter. For new product designs, evaluate the newer PIC18F26K42 family first - it is pin-compatible but adds CIP (Core Independent Peripherals) and improved ADC.

What is an 8-bit microcontroller? An 8-bit microcontroller (MCU) is a single-chip computer that processes data in 8-bit wide paths and integrates CPU core, non-volatile Flash program memory, volatile SRAM data memory, peripherals, and I/O on one die. 8-bit MCUs sit within the broader category of microcontrollers -> embedded processors -> semiconductor ICs. They remain dominant in cost-sensitive and low-power applications because of mature toolchains, predictable real-time behavior, and very low standby current draw, all of which make them the workhorse of the embedded industry. Key features of the PIC18F26K83 include XLP (eXtreme Low Power) technology for sub-µA sleep currents, a 12-bit ADC with computation engine for averaging and oversampling, hardware CAN 2.0B, four 16-bit timers, two I²C, two SPI, two UART, a 5-bit DAC, and CTMU for capacitive touch. The 28-SOIC variant (the SO package) gives 25 user I/O pins, sufficient for sensor nodes and human-interface designs. Architecturally, the part uses a modified Harvard architecture with a 16-bit instruction word and 8-bit data path, a 31-level hardware stack, and a priority-level interrupt controller. ADC² offloads averaging, oversampling, filtering, and threshold detection from the CPU, freeing MIPS for application logic and reducing firmware complexity for touch and sensor signal chains. Typical applications include automotive body and sensor nodes (via CAN), industrial control and sensor hubs, capacitive touch human interfaces, low-power IoT edge nodes, and functional-safety designs that require IEC 61508 SIL capable documentation. The wide 2.3 V to 5.5 V operating range and robust peripherals support battery-powered systems as well as 5 V industrial buses. Design tip: reserve a stable, low-impedance ground plane under the MCU and keep analog traces short when routing the 12-bit ADC inputs to preserve signal integrity.

Key features include Functional Safety (FuSa) support, ultra-low-power XLP sleep currents, 36 instruction set, hardware multiplier, direct and indirect addressing modes, multiple I/O ports (PORTA/PORTB/PORTC), and on-board debug via ICD/ICSP. The 64 KB Flash supports 100K endurance cycles typical, with self-programmability and code protection. The 28-QFN (6x6) package provides 23 I/O pins and a low thermal resistance path through the exposed pad for high-current GPIO drive. The PIC18-Q10 architecture pairs a deterministic 8-bit core with Core Independent Peripherals (CIPs) - CLC, CWG, HLT, and ADC2 - which offload timing-critical tasks from the CPU, improving real-time responsiveness. The 5 V operation directly interfaces to industrial sensors, motor drivers, and noisy environments without external level shifters, reducing BOM and PCB area. Typical applications include industrial sensor nodes, BLDC/PMSM motor control, LED lighting controllers, home appliances, automotive body and chassis ECUs (non-safety), IoT edge nodes with long battery life, and human-machine interfaces. The XLP nanoWatt technology enables sleep currents below 50 nA typical, suiting battery-backed designs. When designing with this device, allocate the exposed pad (EP) as the primary thermal dissipation path, place a 100 nF decoupling capacitor on each VDD pin, and reserve the ICSP/ICD pins for in-circuit programming to simplify firmware iteration.
