PIC18F47J13-I/ML - 8-bit 48MHz 128KB Flash MCU 44-QFN | Microchip
MPN: PIC18F47J13-I/ML ✓ Hoạt độngPIC18F47J13-I/ML Tóm tắt
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 a single silicon die. Within the broader taxonomy, the PIC18F47J13 belongs to the microcontroller category, then to the 8-bit MCU subcategory, then to the Flash-based MCU subcategory, then to the low-power (nanoWatt XLP) MCU subcategory. This hierarchy matters because 8-bit MCUs are typically selected over 32-bit MCUs for cost-sensitive, low-power, deterministic control applications where raw compute throughput is less critical than predictable interrupt latency, low quiescent current, and small package footprint.
Key features include a 12-bit A/D converter with up to 13 input channels, multiple Enhanced Capture/Compare/PWM (ECCP) modules, two UART/USART interfaces, two SPI interfaces, and two I2C interfaces. The Deep Sleep mode with RTCC and WDT can reduce current to deep-sub-uA levels while preserving RAM and a real-time clock, making the part suitable for battery-powered applications. The device operates from 2.0V to 3.6V and is rated -40C to +85C industrial temperature.
The PIC18F47J13 architecture uses a Harvard-style modified RISC core with a hardware multiplier, hardware 8x8 array, and a 16-bit instruction set, providing up to 12 MIPS throughput. The integrated nanoWatt XLP power-management unit enables multiple low-power modes: Run, Idle, Sleep, and Deep Sleep, with selective peripheral clock gating for fine-grained power budgeting.
Typical applications include handheld industrial sensors, low-power remote controls, battery-powered data loggers, USB-to-UART bridges, and small consumer appliances. The wide peripheral set also makes it suitable for HVAC controllers, smart metering, and white-goods user-interface boards.
When designing with this MCU, ensure the VDD/VSS decoupling capacitor network follows the datasheet reference layout and that the QFN exposed pad is soldered to a sufficient copper pour to meet the 31 C/W theta_JC thermal path. Programming is supported by Microchip's MPLAB X IDE with the XC8 compiler and PICkit or ICD debug tools.

Ứng dụng tiêu biểu
PIC18F47J13-I/ML phù hợp cho 6 Áp dụngs: Battery-Powered Sensor Node, Industrial Handheld Terminal, USB to UART Bridge Bridge, Smart Appliance User Interface, HVAC Fan and Damper Controller, Remote Control with Low Standby Current.
Battery-Powered Sensor Node
The PIC18F47J13-I/ML suits battery-powered sensor nodes because its nanoWatt XLP Deep Sleep mode retains RAM and RTCC at deep-sub-uA current while shutting down the CPU and peripherals. At a 3.3V supply with periodic sensor wake-ups every few seconds, average current can drop below 5 uA, enabling multi-year coin-cell operation. The 128 KB Flash stores calibration tables, sensor fusion firmware, and small protocol stacks.
Được đề xuất
Industrial Handheld Terminal
The PIC18F47J13-I/ML fits handheld industrial terminals needing 128 KB of firmware for keypad scanning, LCD driving, barcode decode, and Modbus RTU communication. The 36 I/O pins support a 4x5 matrix keypad, character LCD interface, and UART link to an external radio module. The -40 to +85 C industrial temperature rating and the QFN-EP exposed pad provide robust thermal performance for sealed enclosures.
Được đề xuất
USB to UART Bridge Bridge
For USB-to-UART bridge designs, the PIC18F47J13-I/ML provides the 128 KB needed for the USB HID or CDC stack plus application logic. The dual UART/USART allows simultaneous bridging to two serial devices such as an RS-485 sensor bus and a debug console. The QFN package keeps the bridge footprint under 64 mm^2 on the host PCB, and the exposed pad improves thermal dissipation at continuous USB traffic.
Được đề xuất
Smart Appliance User Interface
The PIC18F47J13-I/ML is well-suited for white-goods user-interface boards that drive segment LCDs, capacitive touch keypads, and triac-based motor controls. The 12-bit ADC with 13 channels reads multiple NTC thermistors for temperature monitoring, while the ECCP modules generate PWM for LED dimming and buzzer tones. The industrial -40 to +85 C range and the QFN package withstand the thermal cycling of kitchen and laundry environments.
Được đề xuất
HVAC Fan and Damper Controller
The PIC18F47J13-I/ML serves as the central controller in HVAC fan and damper modules, where it generates PWM signals for brushless DC fans and reads analog feedback from pressure and temperature sensors. The 128 KB Flash stores proportional-integral control loop code, fault handling, and Modbus firmware for building-automation networks. The nanoWatt XLP Sleep mode reduces standby current when the HVAC system is idle.
Được đề xuất
Remote Control with Low Standby Current
For infrared or sub-GHz RF remote controls, the PIC18F47J13-I/ML keeps standby current at deep-sub-uA levels using its nanoWatt XLP Deep Sleep mode while still allowing a wake-on-RF interrupt. The 128 KB Flash stores button mapping, learning-mode firmware, and optional AES encryption for secure pairing. The 44-QFN package is small enough for slim handheld enclosures and exposes a thermal pad for hand-warmth dissipation.

Ghi chú thiết kế
Estimated: at the maximum 48 MHz clock with all peripherals active and 3.6V VDD, the core current is roughly 15-20 mA. Power dissipation in a 44-QFN with theta_JA of ~31 C/W (4-layer JEDEC test board) means a 35-40 C junction temperature rise above ambient. Always solder the QFN exposed pad to a contiguous VSS copper pour with at least 0.5 square inch of area to meet this thermal path. Skipping the EP connection will force the part into thermal shutdown at sustained high CPU loads.
Place VDD-VSS decoupling capacitors (100 nF ceramic minimum, plus 4.7 uF bulk) within 3 mm of the VDD/VSS pin pairs. The PIC18F47J13 has multiple VDD/VSS pin pairs (pins 10/9, 20/19, 39/38); each pair should have its own local decoupling. Use a star-ground topology tying all VSS pins and the EP into a single low-impedance ground pour, and keep the ICSP PGC/PGD traces short and away from switching nodes.
When entering Deep Sleep mode, ensure the RTCC and WDT are explicitly enabled or disabled in firmware before the SLEEP instruction. The Deep Sleep current is specified with these peripherals configured - leaving them running accidentally will pull current out of the sub-uA range into the tens-of-uA range. Use the DCxH/L configuration registers to gate unused peripherals, and clear the PMSLP bit on any active peripheral you do not want to retain.
Do not exceed the absolute maximum VDD of 4.0 V on the PIC18F47J13 - it is a 3.3V part, not a 5V tolerant one. PIC18F J-series parts are NOT 5V tolerant on any I/O; apply external level shifting if interfacing to 5V logic. Also note that some legacy PIC18 J-series ports have analog-input multiplexers that must be explicitly configured to digital mode via the ANSELx registers, otherwise the pins read as analog and never toggle high or low.
Keep the secondary oscillator (SOSC) traces on RC1/RC0 short and surrounded by ground to minimize radiated emissions. If you are not using SOSC, leave RC1 and RC0 as digital I/O but disable the SOSC bit in OSCCON to prevent the oscillator from running. For noise-sensitive ADC readings, route analog signals (AN0-AN12) on a separate inner layer with a ground plane below and avoid crossing any switching traces.
