PIC18F27J13-I/SS Visão geral
An 8-bit microcontroller (MCU) is a compact computer-on-a-chip containing a CPU, program memory (Flash/ROM), data memory (RAM), and integrated peripherals such as ADCs, timers, communication interfaces, and I/O ports. PIC18 J-series devices sit in the PIC microcontroller family hierarchy as PIC -> PIC18 -> PIC18 J-series, designed for cost-sensitive applications that need higher memory density and peripheral flexibility than baseline PIC16 parts. The J-series is distinguished from K-series parts by its 2.0-3.6 V core supply and 5.5 V tolerant I/O, making it ideal for mixed-voltage systems.
Key features include 128 KB (64K x 16) Flash program memory, 4 KB RAM, 12-bit A/D converter with up to 10 channels, two comparators, two CCP/ECCP modules, four 8/16-bit timers, hardware RTCC, two MSSP (SPI/I2C) ports, two enhanced USART modules, and a 10-bit DAC reference output. The deep-sleep mode current is in the hundreds of nanoamperes, while run-current is roughly a few mA per MHz, enabling years of battery life on coin cells.
The PIC18F27J13-I/SS uses a modified Harvard RISC architecture with a 16-bit instruction word and 8-bit data path. Code is executed from Flash via a 2-stage pipeline that lets the next instruction pre-load while the current one executes, supporting the 12 MIPS throughput at 48 MHz. Peripherals are memory-mapped through SFRs and configured via PPS (Peripheral Pin Select) for flexible pin assignment.
Typical applications include portable medical devices, low-power wireless sensor nodes, USB HID peripherals (with the PIC18 USB J-series siblings), consumer appliances, smart meters, and industrial control boards. The wide memory and deep-sleep capability suit applications that wake occasionally to log or transmit data.
When designing with this device, ensure the core VDD stays within 2.0 V to 3.6 V while the I/O pins can be pulled up to 5.5 V for mixed-voltage buses. Decouple VDD/VSS with 100 nF ceramic caps close to each pin pair, and configure unused I/O as outputs to minimize sleep current. Use the PPS system to remap peripherals to alternate pins if board layout constraints change.

Aplicações típicas
PIC18F27J13-I/SS é adequado para 7 aplicaçãos: Battery-Powered Wireless Sensor Nodes, Smart Metering and Energy Monitoring, Industrial Control and Sensor Conditioning, Consumer Appliance User Interface Boards, Portable Medical and Wellness Devices, Automotive Body and Comfort Electronics, USB HID Peripherals (USB-less variant baseline).
Battery-Powered Wireless Sensor Nodes
The PIC18F27J13-I/SS is well suited to battery-powered wireless sensor nodes thanks to its nanoWatt XLP deep-sleep mode (hundreds of nA with RTCC running) and 12 MIPS throughput at 48 MHz. The 2.0-3.6 V core with 5.5 V tolerant I/O simplifies interfacing to a 3.6 V LiSOCl2 primary cell while still allowing direct connection to 5 V sensors without level shifters. In a typical design the MCU wakes on RTCC alarm every few seconds, samples a sensor via the 12-bit ADC, and transmits via a sub-GHz radio before re-entering deep sleep. The 128 KB Flash and 4 KB RAM easily fit protocol stacks such as Wireless M-Bus or proprietary sensor frameworks.
Recomendado
Smart Metering and Energy Monitoring
The PIC18F27J13-I/SS fits smart metering endpoints that need calibrated single-phase energy measurement and long battery life. The 12-bit ADC with up to 10 channels supports simultaneous voltage and current sensing from CT/PT sensors, while the hardware CCP/ECCP modules drive power-calculation timers and zero-crossing detection. The 5.5 V tolerant I/O lets the MCU directly interface to 5 V metrology front-ends without level shifters. Deep-sleep mode current in the hundreds of nA extends coin-cell or supercap backup lifetime to years. The 128 KB Flash accommodates DLMS/COSEM or proprietary metering stacks plus secure firmware update routines.
Recomendado
Industrial Control and Sensor Conditioning
The PIC18F27J13-I/SS serves as a low-cost controller in industrial control boards where 8-bit processing, 12-bit ADC precision, and a wide industrial temperature range are sufficient. Its 48 MHz core easily handles Modbus RTU framing, PWM actuator control via ECCP, and encoder feedback using the CCP and timer modules. The 2.0-3.6 V core plus 5.5 V tolerant I/O simplifies mixed-voltage interfaces to 24 V industrial signal-conditioning rails through external resistor dividers. The 28-SSOP package is footprint-compatible with the larger PIC18F46J13 part, easing upward migration when code size grows.
Recomendado
Consumer Appliance User Interface Boards
The PIC18F27J13-I/SS powers user-interface boards in washing machines, ovens, and HVAC thermostats where cost and reliability outweigh raw MIPS. Its 12-bit ADC reads thermistor and potentiometer inputs for temperature and setpoint values, while two EUSART modules handle the main appliance controller link and an optional service/diagnostic port. nanoWatt XLP deep-sleep lets the UI board sit idle in standby at microamp-level current draw when the appliance is off. The 128 KB Flash supports rich LCD menu firmware and capacitive-touch sensing via the comparators and CTMU module. The 28-SSOP package is widely accepted by white-goods contract manufacturers.
Recomendado
Portable Medical and Wellness Devices
The PIC18F27J13-I/SS fits portable medical and wellness devices such as pulse oximeters, glucose meters, and electronic thermometers that demand low power, small package, and integrated analog. Its 12-bit ADC digitizes photodiode or bio-impedance sensor signals with sufficient resolution for trend monitoring, and the 10-bit DAC reference calibrates the analog front-end. nanoWatt XLP operation extends battery life on coin cells to months or years between replacements. The 5.5 V tolerant I/O allows direct drive of piezo buzzer alarms and LED indicators from higher-voltage rails. Industrial -40C to +85C temperature grade supports outdoor or wearable use cases.
Recomendado
Automotive Body and Comfort Electronics
The PIC18F27J13-I/SS is suitable for non-safety automotive body and comfort applications such as seat controllers, mirror adjusters, ambient lighting, and HVAC blend-door actuators where the I-grade temperature range (-40C to +85C) is acceptable. The two CCP/ECCP modules generate PWM signals for motor speed control and LED dimming, while the comparators monitor current sense for fault detection. The 128 KB Flash supports LIN slave stacks and proprietary body-controller protocols. For under-hood or AEC-Q100 qualified applications, choose the PIC18F27J53 or PIC18F K-series with Q-1 suffix instead.
Recomendado
USB HID Peripherals (USB-less variant baseline)
Although the PIC18F27J13-I/SS does not include USB, it serves as the firmware-compatible non-USB baseline for designers prototyping USB HID peripherals on the sibling PIC18F27J53. Code that handles sensor acquisition, button processing, and command parsing runs unmodified on the PIC18F27J13-I/SS while engineers validate the analog and mechanical subsystems before stepping up to the USB-enabled part. Both parts share the 128 KB Flash, 4 KB RAM, 12-bit ADC, and 28-SSOP pinout, so firmware libraries and PCB layouts remain identical between development and production variants.

Notas de projeto
The PIC18F27J13 core VDD must remain within 2.0 V to 3.6 V even though its I/O pins are 5.5 V tolerant. Place a 100 nF ceramic decoupling capacitor as close as possible to each VDD/VSS pin pair (pin 20/19 and pin 8/7) and add a bulk 4.7 uF or 10 uF tantalum/ceramic near the supply pins. For battery applications with peak load above 50 mA (e.g., radio TX bursts), add a local 10 uF bulk to prevent VDD droop during transmit. The I/O pins can be pulled to 5 V even when the core is at 2.5 V, but never pull VDD itself above 3.6 V.
When laying out the 28-SSOP footprint, place the IC with pin 1 marker at top-left and follow the standard SSOP 0.65 mm pitch. Keep crystal traces from OSC1/OSC2 short and symmetric to avoid stray capacitance, and route the MCLR pull-up directly to VDD with a 10 k resistor. If using ICSP, ensure PGC/PGD (RB6/RB7) are accessible for in-circuit programming without disturbing other signals. Analog inputs should be guarded with a ground trace on each side to reduce digital crosstalk into the 12-bit ADC.
Do not confuse the PIC18F27J13-I/SS with the PIC18F27J53-I/SS - the former lacks USB and the latter includes it. Avoid powering the core above 3.6 V or pulling I/O above 5.5 V. Configure unused I/O as outputs (not inputs) to minimize deep-sleep current leakage. When migrating from PIC18F26J13, the peripherals are identical but Flash is halved, so verify that linker section placement does not exceed 64 KB. Always configure PPS (Peripheral Pin Select) lock bits if peripherals are mapped to non-default pins.
