PIC18F26J13-I/SO 概要
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash), data memory (RAM), peripherals, and I/O on one die. The PIC18 architecture belongs to the broader Modified Harvard RISC family, and within Microchip's portfolio it sits in the PIC18F sub-family of flash-based, general-purpose microcontrollers. PIC18F parts are positioned between the baseline PIC10/12/16 and the 16-bit dsPIC/PIC24 families, offering more peripherals and addressing modes than baseline parts while keeping the simple 8-bit instruction set.
Key features include 64KB (32K x 16) of Flash program memory, 4KB of RAM, a 12-bit ADC with multiple channels, multiple Enhanced USART, I2C and SPI interfaces, and nanoWatt XLP technology that includes deep sleep mode for power-constrained applications. The 28-pin SOIC package supports up to 25 digital I/O pins while remaining easy to hand-solder and breadboard-prototype.
Technically, the PIC18F26J13 uses a 16-bit instruction word with a 16-bit data path and runs at up to 12 MIPS from a 48 MHz internal oscillator, simplifying designs that do not require an external crystal. The XLP deep-sleep mode allows current consumption in the nanoampere range, and the integrated RTCC (Real-Time Clock and Calendar) plus multiple capture/compare/PWM modules support motor, lighting, and timing-intensive applications.
Typical applications include industrial control, consumer electronics, automotive body and accessory subsystems, low-power sensor nodes, USB/HID peripherals, and small appliance controls. The combination of peripheral richness, low power, and a low-pin-count SOIC package also makes this MCU popular in cost-sensitive designs where a 32-bit Cortex-M device would be over-spec.
When designing with this device, ensure the supply voltage is within the 2.0V-3.6V core Vdd range (typical for J-series parts) and that the I/O voltage rails are configured correctly to avoid damage. Programming and debugging require a Microchip ICD tool such as MPLAB ICD 3, ICD 4, or PICKit 4.
This page synthesizes distributor pricing, drop-in alternatives in the same 28-SOIC package, and practical design notes not found in the manufacturer datasheet, helping engineers select the right part and avoid common pitfalls.

主な用途
PIC18F26J13-I/SO の用途: 8 件s: Industrial Control and Automation, Consumer Electronics and Home Appliances, Automotive Body and Accessory Modules, Low-Power Wireless Sensor Nodes, USB HID and Human Interface Devices, Motor Control and PWM Drivers, Test and Measurement Handhelds, Lighting Control and LED Drivers.
Industrial Control and Automation
The PIC18F26J13-I/SO is well suited for industrial control with 25 digital I/O pins, 12-bit ADC, and PWM outputs that directly drive relays, solenoids, and small motors. Its -40C to +85C industrial temperature rating and 64KB Flash support complex ladder-logic-equivalent control code plus bootloader-based field updates. The 48 MHz core (12 MIPS) executes PID loops fast enough for closed-loop control of temperature, flow, or pressure processes, and nanoWatt XLP deep-sleep extends battery life in remote sensor-actuator nodes.
おすすめ
Consumer Electronics and Home Appliances
The PIC18F26J13-I/SO is widely used in consumer appliances such as washing machines, microwave ovens, and smart thermostats where cost-effectiveness and reliability matter. The 64KB Flash stores user-interface state machines and look-up tables for sensor calibration, while 4KB RAM buffers display and keypad input. The 28-SOIC package keeps the BOM small in space-constrained enclosures, and nanoWatt XLP allows standby power in the single-digit milliwatt range for energy-star compliance.
おすすめ
Automotive Body and Accessory Modules
The PIC18F26J13-I/SO targets automotive body modules such as window lifters, seat controllers, and lighting drivers where 25 I/O pins interface to relays, MOSFET drivers, and LIN bus. Its industrial -40C to +85C rating covers cabin environments, while 64KB Flash accommodates CAN/LIN stack and diagnostic firmware. PWM and capture modules drive brushless DC fans and LED dimming, and the small 28-SOIC footprint simplifies integration into tight module enclosures.
おすすめ
Low-Power Wireless Sensor Nodes
Battery-powered sensor nodes benefit from the PIC18F26J13-I/SO's nanoWatt XLP deep-sleep current in the nanoampere range. The 12-bit ADC reads temperature, humidity, or battery voltage while the MCU sleeps, then wakes on a timer interrupt to transmit via UART-attached radio. The 64KB Flash holds protocol stacks such as Modbus RTU or proprietary RF protocols, and the 28-SOIC package enables miniature PCB designs for wearable or IoT form factors.
おすすめ
USB HID and Human Interface Devices
The PIC18F26J13-I/SO can serve as a USB HID device using Microchip's USB stack for keyboards, mice, custom HID controllers, and game controllers. With 64KB Flash it fits the USB stack plus application code, while 4KB RAM supports HID report buffers and ring buffers for incoming USB traffic. The 48 MHz core sustains 12 MIPS, sufficient to handle USB polling at 1 ms intervals alongside application logic. The 28-SOIC package enables compact dongle-style product designs.
おすすめ
Motor Control and PWM Drivers
The PIC18F26J13-I/SO handles brushed DC and small BLDC motor control via its capture/compare/PWM modules. The 12-bit ADC reads back-EMF or current shunt for closed-loop control, and 64KB Flash stores motor profiles plus field-orientation lookup tables. With 25 I/O pins it interfaces to gate drivers and Hall sensors, and the 28-SOIC package simplifies integration into motor-driver PCBs. nanoWatt XLP reduces standby consumption when the motor is idle for energy efficiency.
おすすめ
Test and Measurement Handhelds
Handheld test instruments use the PIC18F26J13-I/SO for measurement acquisition and LCD/keypad user interface. The 12-bit ADC samples multiple analog channels for multimeter-class measurements, while 64KB Flash holds calibration tables and UI state machines. The 4KB RAM buffers measurement data for averaging, and the 28-SOIC package fits inside small instrument enclosures. Enhanced USART plus SPI enable communication with external ADCs, DACs, or wireless modules.
おすすめ
Lighting Control and LED Drivers
The PIC18F26J13-I/SO drives LED arrays via PWM outputs for dimming, color mixing, and dynamic lighting effects. The 12-bit PWM resolution enables smooth dimming curves, and 64KB Flash stores lighting presets and DMX-like protocols. The 25 I/O pins interface to multiple LED strings, and nanoWatt XLP reduces standby consumption for smart-lighting and architectural-lighting fixtures. The 28-SOIC footprint keeps the BOM small in cost-sensitive lighting products.

設計ノート
The PIC18F26J13-I/SO is a 3.3V-native J-series part - confirm Vdd is within 2.0V to 3.6V before applying power. For 5V systems, level-shift all I/O via the RP-pin remappable peripheral paths or choose a K-series part (PIC18F25K22-I/SO or PIC18F25K80-I/SO) that natively supports 5V. Decoupling: place 100 nF ceramic + 10 uF bulk as close as possible to each Vdd/Vss pin pair.
Watch the AVDD/AVSS analog supply pins and VREF+/VREF- pins (RA2/RA3 in SOIC-28) - tie AVDD to Vdd and AVSS to Vss, but isolate VREF with its own 100 nF capacitor if used. Also remember that all remappable peripheral pins (RPx) must be explicitly unlocked and remapped in firmware - they default to GPIO after reset and stay GPIO until PPS configuration runs.
For 48 MHz operation, keep the high-speed signal traces short and place decoupling capacitors within 2 mm of Vdd/Vss pins. Use a ground pour on the top layer under the MCU and stitch vias to a ground plane. The ICSP pins (RB6/RB7) must be brought out to a programming header or test pads - do not strap these pins to ground or power, or programming will fail.
Estimated: at 48 MHz, Vdd=3.3V, and typical I/O loading (8mA per pin), the PIC18F26J13-I/SO dissipates around 50-100 mW during active operation. The 28-SOIC package has theta_JA around 80 C/W, so a 100 mW dissipation gives an 8C junction rise above ambient - well within the -40C to +85C industrial range without special thermal management.
When routing SPI or EUSART at high baud rates (>1 Mbps), keep trace lengths matched within 2 mm and add a 33 ohm series resistor at the source to dampen reflections. For I2C, populate both SCL1 (RC3) and SDA1 (RC4) lines with 4.7 kohm pull-ups to Vdd and avoid routing near switching power nodes to prevent noise coupling into the I2C bus.
