PIC18F27J13T-I/ML 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and programmable I/O peripherals. The PIC18 family uses an enhanced 8-bit RISC Harvard architecture with 16-bit-wide instructions, enabling most instructions to execute in a single cycle. PIC MCUs target cost-sensitive embedded applications where deterministic real-time response, low power consumption, and ease of development matter more than raw computational throughput, and they sit in the broader category of 8-bit microcontrollers alongside 8051 and AVR devices.
Key features of this device include 128 KB self-programmable Flash, 3.8 KB RAM, 8-channel 10-bit ADC, two USART modules, two SPI and two I2C peripherals, and up to 22 digital I/O pins. Microchip's nanoWatt XLP technology adds a deep-sleep mode drawing nanoamp-level current, making the device well suited to battery-powered designs. The integrated RTCC and CTMU peripherals reduce external component count for touch and timing applications.
Architecture-wise the PIC18F27J13 uses an internal PLL to derive a 48 MHz system clock from a wide range of external crystals or internal oscillator sources. The 28-pin QFN package leaves I/O count intentionally limited but offers an exceptionally small 6x6 mm footprint with an exposed thermal pad, while keeping all analog and digital peripherals accessible from the remaining GPIO.
Typical applications include consumer electronics control boards, low-power IoT sensor nodes, battery-powered handheld instruments, USB peripherals with on-chip transceivers, home automation gateways, and educational/development boards. Designers often choose this MCU when they need more Flash than the PIC18F25 series but fewer pins than the 44-pin PIC18F46 variants, with nanoWatt XLP enabling years of operation from a coin cell.
For new designs, verify the latest silicon revision in the datasheet before commit because the PIC18F27J13 family has multiple silicon revs. Ensure decoupling capacitors are placed as close as possible to VDD/VDDCORE pins and that the QFN thermal pad is soldered to a properly sized ground copper pour for thermal dissipation.
This page synthesizes distributor pricing, drop-in cross references, and practical design notes that go beyond what appears in any single manufacturer document, giving engineers and procurement teams a single source for technical and commercial decisions about this MCU.

主な用途
PIC18F27J13T-I/ML の用途: 6 件s: Consumer Electronics Control, Battery-Powered IoT Sensor Node, Industrial Control and HMI, Handheld Test Instruments, Home Automation Gateway, Educational Development Board.
Consumer Electronics Control
The PIC18F27J13T-I/ML fits consumer electronics control boards that need 64 to 128 KB of code space and nanoWatt XLP standby. The 48 MIPS throughput handles simple UI loops, capacitive touch sensing via the CTMU, and PWM-driven lighting or motor control without external logic. Place the MCU between a 3.3V LDO and downstream actuators; nanoWatt XLP deep-sleep keeps idle power budgets in the microamp range, which is critical for wall-powered standby targets such as Energy Star.
おすすめ
Battery-Powered IoT Sensor Node
The 128 KB Flash and nanoWatt XLP deep-sleep mode make the PIC18F27J13T-I/ML ideal for wireless sensor nodes running on coin cells or Li-SOCl2 primaries. The internal 48 MHz PLL eliminates an external high-speed crystal, saving board area and quiescent draw. Drive the radio from a GPIO-controlled LDO and use the RTCC for periodic wake; this matches years-of-life targets for remote environmental, agricultural, and smart-metering deployments.
おすすめ
Industrial Control and HMI
The PIC18F27J13T-I/ML serves 24V industrial HMI panels and small PLCs where 22 I/O pins, 8-channel 10-bit ADC, and 128 KB Flash are sufficient. The 2.0V to 3.6V supply range requires a regulated 3.3V rail, and the QFN exposed pad dissipates local power dissipation from I/O switching. Use the I2C bus to attach EEPROM or RTC and the SPI bus for an LCD controller, while the USART links to RS-485 transceivers for fieldbus connectivity.
おすすめ
Handheld Test Instruments
Handheld multimeters and clamp meters benefit from the PIC18F27J13T-I/ML's combination of low-power deep sleep, 10-bit ADC for measurement front-ends, and 22 GPIO for keypad/display multiplexing. The 128 KB Flash accommodates calibration tables, user UI in C, and bootloader for firmware updates via the ICSP interface. nanoWalt XLP keeps leakage well below 1 uA in standby so two AA cells can run the meter for years.
おすすめ
Home Automation Gateway
PIC18F27J13T-I/ML's dual USART and dual I2C interfaces let it bridge Wi-Fi/BLE modules and sensor peripherals at the same time as running the local control loop in firmware. Place the device near a 3.3V regulator and add a small EEPROM for persistent configuration. The industrial temperature grade (-40C to +85C) covers attic and garage installations, and nanoWatt XLP maintains quiescent draw in the microamp range overnight.
おすすめ
Educational Development Board
The 128 KB Flash and full J-series peripheral set make PIC18F27J13T-I/ML a strong choice for teaching embedded systems. Its QFN 6x6 mm footprint is larger than BGA but small enough for hand-soldered breakout boards, and the same PICkit 4 debugger used for development supports all J13 variants. Combine with on-board USB-to-UART, LEDs, and a potentiometer to demonstrate ADC, PWM, and timers in a single lab session.

設計ノート
PIC18F27J13T-I/ML requires a regulated 2.0V to 3.6V supply; place a 100 nF decoupling capacitor as close as possible to each VDD/VSS pair. For battery-powered designs add a 10 uF bulk capacitor near the MCU and use the deep-sleep mode plus RTCC wake to achieve single-digit microamp idle current; verify the chosen LDO's quiescent current is below the MCU's deep-sleep floor.
The 28-QFN 6x6 mm package exposes a thermal pad on pin 28 which must be soldered to a ground copper pour of at least 50 mm^2. Estimated: at 48 MHz with full GPIO switching and 3.3V supply the MCU draws about 15 mA total, dissipating roughly 50 mW which is well below thermal limits, but adequate copper still improves EMI and long-term reliability in enclosed enclosures.
Keep the ICSP clock (PGC, pin 16) and ICSP data (PGD, pin 17) traces short and away from switching signals or oscillator traces to avoid programming failures. Trace the RESET line (MCLR if implemented) with a 100 ns edge filter using a 10 kohm pull-up and a capacitor near the MCU; for in-circuit programming verify the line is not driven by external circuitry during programming.
Do not assume PIC18F27J13T-I/ML supports USB full-speed; the J53 variant is required for on-chip USB. Watch for silicon revision differences - some errata items are only fixed in revision B3 or later, so check the device ID register before volume commit. Configuration bits must be set correctly otherwise the oscillator source remains unconfigured and the device appears dead on first power-up.
