PIC18F26K22-I/SP Обзор
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, volatile data memory, and configurable peripherals. The 8-bit class targets cost-sensitive, deterministic control tasks such as sensor interfacing, motor driving, user I/O handling, and simple protocol bridging. PIC18F devices sit above baseline PIC10/12/16 parts by offering a 16-bit instruction word, a 31-level hardware stack, linear memory access, and a richer interrupt controller — features useful when C compilers are used and code density matters. PIC18F 'K' series parts add nanoWatt XLP for sleep currents often below 100 nA typical.
Key features include nanoWatt XLP extreme low-power with multiple idle/sleep modes, 25 I/O pins with peripheral pin select (PPS), two Enhanced USART modules, two MSSP (SPI/I2C) ports, a 12-bit ADC with computation (ADC2) oversampling, multiple 16-bit timers, and a charge time measurement unit (CTMU) for capacitive touch and ratiometric sensing. The device operates from 1.8 V to 5.5 V on wide-range Fosc and supports on-board 8 MHz to 64 MHz PLL-based operation.
The PIC18F26K22 uses a Harvard architecture with separate 16-bit instruction and 8-bit data paths, 31-level hardware stack, and an internal 16 MHz 0.5% accurate oscillator (HFINTOSC) that can be locked to 16 MHz or 64 MHz via the 4x PLL. The 12-bit ADC2 includes hardware averaging and automatic threshold scanning for low-MIPS sensor acquisition.
Typical applications include consumer remote controls, battery-powered sensor nodes, capacitive touch user interfaces, industrial control panels, USB-to-UART bridges (with external MCU-side USB transceiver), and home-automation HMI modules. The wide 1.8V-5.5V supply range suits single-cell Li-ion or two-AA designs that must hibernate in dark rooms for months.
When designing with this device, the Watchdog Timer, Brown-out Reset and POR should be configured to match the application's supply-rail behavior. PPS remapping lets designers reassign peripheral I/O to alternate pins to ease PCB routing, but each pin can serve only one peripheral function at a time. Use the MPLAB PICkit 5 or ICD 4 for programming and debugging.

Типичное применение
PIC18F26K22-I/SP подходит для 6 применениеs: Battery-Powered IoT Sensor Nodes, Consumer Remote Controls, Capacitive Touch User Interfaces, Industrial Control Panels, HVAC Sensor Modules, USB HID Bridge / UART Emulation Dongles.
Battery-Powered IoT Sensor Nodes
The PIC18F26K22-I/SP suits battery-powered IoT sensor nodes because nanoWatt XLP holds sleep current below 100 nA typical in Retention mode. With 64 KB Flash and 3896 B SRAM, it can run a 6LoWPAN or LoRaWAN style stack on a private sub-GHz radio plus on-chip ADC2 sweeping a sensor farm. Unlike simpler PIC16 parts, the K22 provides PPS for clean PCB routing when a 2.4 GHz antenna needs to be kept away from digital lines.
Рекомендуется
Consumer Remote Controls
Universal remote controls benefit from the PIC18F26K22-I/SP's 25 I/O and dual MSSP/I2C channels to scan 4x4 key matrices while driving IR LED drivers through PWM. NanoWatt XLP sleep keeps standby drain under a microamp, letting two AAA cells last the product lifetime. Compared with smaller PIC16F parts, the K22's PPS eliminates the need for remappable-pin PCB workarounds in densely packed handheld enclosures.
Рекомендуется
Capacitive Touch User Interfaces
The PIC18F26K22-I/SP drives capacitive touch sliders and buttons using the on-board CTMU, with 12-bit ADC2 achieving reliable touch sensing without dedicated touch controllers. CTMU's hardware timing translates capacitance changes into counts faster than polled ADC alone. Designers can wake the MCU only when a touch event is detected, then return to nanoWatt XLP sleep within microseconds after firmware processing.
Рекомендуется
Industrial Control Panels
Industrial control panels favor the PIC18F26K22-I/SP because of its 5.5 V tolerance on most I/O pins (no need for level shifters on 5 V buses), the 12-bit ADC with 19 channels for analog sensor trimming, and two EUSART ports for RS-485 / RS-232 / DMX traffic. The 28-SPDIP through-hole package simplifies hand-rework in factory-floor retrofits where surface-mount rework stations are scarce.
Рекомендуется
HVAC Sensor Modules
The PIC18F26K22-I/SP suits HVAC sensor modules because its 1.8 V to 5.5 V supply range tolerates typical 24 VAC rectified rails after LDO regulation, while nanoWatt XLP keeps idle draw from a sealed sensor housing low enough to meet building-energy standards. Two MSSP ports can drive SPI temperature/humidity chains simultaneously, freeing up PPS-mapped I/O for actuator drivers.
Рекомендуется
USB HID Bridge / UART Emulation Dongles
USB HID bridges benefit from the PIC18F26K22-I/SP's dual EUSART + 2x MSSP plus PPS remapping, allowing one EUSART to handle debug logging and the other to expose a CDC-style channel via USB HID-to-UART conversion. The 64 MHz CPU runs interrupt-driven USB descriptors without dedicated hardware USB. Compared with lower-pin PIC18F parts, the K22's 25 I/O allow a single MCU to handle both bus side and target UART side plus indicators.

Заметки по проектированию
The PIC18F26K22-I/SP uses nanoWatt XLP to reach sub-100 nA typical current in Retention sleep mode. To achieve this, configure the FVR, ADC, comparators, and unused peripherals as off before executing the SLEEP instruction; the data sheet ERRATA documents that forgetting to disable the FVR can add ~30 uA continuous draw.
Operating temperature for the I/SP is -40 C to +85 C industrial range. For retrofit-style panel designs that live inside sealed enclosures, derate maximum Fosc at high ambient using the data sheet curves; at 85 C ambient, design to a CPU clock of 16 MHz or below to retain thermal margin.
Configuration bits must be set explicitly: LVP=1 enables ICSP with PGM pin, LVP=0 disables it and frees RC0/RC1. Forgetting to disable LVP can result in RB5/RC0 acting as temporary programming lines during ramp-up. Use an external pull-down on PGM for high-reliability starts unless you commit to LVP=0.
Place a 0.1 uF decoupling capacitor within 5 mm of each VDD pin and a 1 uF bulk capacitor within 10 mm of the package. The AVDD pin (when used with analog features) needs its own 10 uH inductor or ferrite-bead and 10 uF bypass cap, separating digital and analog supply from MCU side. For SPI runs above 10 MHz, route on inner layer with grounded adjacent via fence.
Информация о соответствии
RoHS and lead-free compliant per Microchip product page. Not AEC-Q100 qualified - this is an industrial-grade part, not an automotive part. The I/SP suffix indicates industrial temperature grade (-40 C to +85 C).
