PIC18F67J10-I/PT Présentation
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and a rich set of peripheral interfaces into one device. The PIC18 family uses an enhanced RISC architecture with 16-bit opcodes and 8-bit data paths; the 'J' sub-family is designed around a 2.5V/3.3V core and offers multiple low-power (nanoWatt) modes for battery-aware designs. MCUs sit beneath the broader hierarchy of microprocessors and embedded processors, occupying the same tier as ARM Cortex-M0/M3 devices in the embedded-system taxonomy.
Key features of the PIC18F67J10 include four serial ports (two MSSP for I2C and SPI, plus two enhanced USARTs with LIN support), a 10-bit A/D converter with up to 16 channels, two analog comparators, two CCP modules plus one ECCP, four timers (Timer0/1/2/3), and a 16-bit parallel slave port for external memory expansion. The 54 digital I/O pins can sink/source up to 25 mA, supporting direct LED drive in some topologies.
The architecture is built on a flash-based CMOS process with on-chip debugging via ICD and self-programming capability. The 16-bit wide instruction word and 8-bit datapath provide deterministic interrupt latency, while the 31-level hardware stack supports C compilers (MPLAB XC8) and the traditional PIC assembly toolchain.
Typical applications include industrial control panels, HVAC and home-automation gateways, automotive LIN slave nodes, USB/connectivity bridges, and human-machine interface (HMI) modules that need many I/Os and a low-power operating mode. Cost-sensitive multi-serial designs (e.g. RS-232 plus RS-485 plus I2C sensor plus SPI display) particularly benefit from the four-port integration.
Designers should note that the PIC18F67J10 is a 2.5V/3.3V part (VDDCORE regulated internally); the I/O pins are 5V-tolerant. Always decouple VDD/VSS with 100 nF plus bulk capacitors and place them within 2 mm of the package pins.

Applications typiques
PIC18F67J10-I/PT convient pour 7 applications: Industrial Control Panels and HMIs, Automotive LIN Slave Nodes, HVAC and Home-Automation Gateways, Multi-Serial Industrial Sensor Hubs, Medical Monitoring Devices (non-implantable), USB-to-Serial Bridge and Connectivity Modules, Educational and Development Platforms.
Industrial Control Panels and HMIs
The PIC18F67J10-I/PT is well-suited to industrial control panels where the 54 digital I/O pins drive keypads, LED indicators, and relay banks while the four serial ports (2x MSSP I2C/SPI plus 2x LIN-capable EUSART) handle sensor and HMI modules. The 128 KB Flash supports a full graphical menu system written in MPLAB XC8, and the 10 MIPS throughput at 40 MHz keeps display refresh responsive. The -40C to +85C industrial temperature grade matches factory-floor specifications, and the parallel slave port can interface to an external graphics LCD controller. PIC18F66K80T-I/PT is a recommended companion MCU for distributed I/O expansion nodes on the same RS-485 bus.
Recommandé
Automotive LIN Slave Nodes
Body-electronics LIN slave modules benefit from the PIC18F67J10-I/PT's two enhanced USARTs with LIN 1.3 support, allowing simultaneous LIN bus comms and a debug/K-line UART. The 10-bit A/D with up to 16 channels reads switch contact and sensor inputs directly, while the two CCP/ECCP modules drive small DC motors or PWM-controlled LEDs. Industrial temperature operation handles under-dash conditions. For master nodes or gateway designs, the PIC18F46K80T-I/PT offers an upgraded K-series core and CAN-capable ECAN, while the PIC18F25K80-I/P is the smaller-pinout cousin for end-node ECUs.
Recommandé
HVAC and Home-Automation Gateways
Connected thermostats and HVAC controllers use the PIC18F67J10-I/PT to bridge multiple low-speed serial buses (I2C for temp/humidity sensors, SPI for an LCD or WiFi co-processor, plus a UART for the HVAC bus). The 4 KB RAM is sufficient for protocol stacks and a small RTOS kernel, while the 128 KB Flash accommodates a wireless provisioning app. The 16-bit parallel slave port allows direct interface to an external Ethernet controller or a TFT display driver. For sensor-side endpoints, PIC18F46K22-I/P is the natural lower-pinout complement, and PIC18F26K22-I/P fits behind each room thermostat.
Recommandé
Multi-Serial Industrial Sensor Hubs
Multi-sensor data-acquisition hubs benefit from the PIC18F67J10-I/PT's combination of two I2C buses, one SPI bus, and two UARTs - enabling simultaneous reading of up to four sensor chains (I2C temp+humidity, SPI pressure sensor, UART GPS module, plus a wired debug port). The 10-bit ADC with 16 channels handles analog inputs like strain gauges and 4-20 mA loop signals. The 4 KB RAM buffers incoming packets, and the 128 KB Flash holds the protocol-conversion firmware. PIC18F4620-I/PT is a recommended secondary MCU when 5V-tolerant I/O is needed for legacy analog front-ends.
Recommandé
Medical Monitoring Devices (non-implantable)
Patient monitors and bedside infusion pumps use the PIC18F67J10-I/PT for multi-parameter sensor readout. The 10-bit A/D with up to 16 channels simultaneously samples temperature, SpO2, respiration, and pressure signals. The two MSSP ports handle I2C digital sensors (e.g., a temperature IC) and SPI to an LCD or audio codec, while the parallel slave port can connect to an external DSP or FPGA for signal processing. The -40C to +85C operation covers clinical environments. Note: this MCU is not a medical-grade 'Q' part; for IEC 60730-class safety functions, Microchip's dsPIC33 or PIC24 are recommended. PIC18F46K22-I/PT and PIC18F45K22-I/PT are the 40-pin companions.
Recommandé
USB-to-Serial Bridge and Connectivity Modules
Although the PIC18F67J10-I/PT lacks native USB, its dual MSSP and dual EUSART architecture makes it ideal as a host-side bridge MCU that talks UART/SPI/I2C to a separate USB controller (e.g., PIC18F2550 or MCP2200). The 4 KB RAM buffers high-throughput serial streams, while the 128 KB Flash hosts the protocol-translation firmware. The parallel slave port allows DMA-style bulk transfer to the USB controller's buffer. The PIC18F46J50-I/PT and PIC18F4550-I/PT are recommended as USB-equipped hosts on the same 64-pin TQFP footprint for unified PCB layout.
Recommandé
Educational and Development Platforms
Universities and training centers use the PIC18F67J10-I/PT on 64-pin TQFP development boards because it exercises nearly the full PIC18 peripheral set: dual MSSP, dual EUSART, two CCP, one ECCP, two comparators, 10-bit ADC, and parallel slave port. The 128 KB Flash accommodates real-world firmware projects beyond simple examples, while the 4 KB RAM supports C-language coursework using MPLAB XC8. Industrial temperature rating enables lab-to-outdoor project progression. Companion MCUs for student labs include PIC18F4520-I/PT (40-pin DIP-friendly) and PIC18F4620-I/PT (more RAM, larger Flash).

Principaux différenciateurs
- Highest memory density in the 64-pin J-series family (vs PIC18F65J10-I/PT)
- Lower 5V tolerance vs K-series requires careful bus design (vs PIC18F66K80-I/PT)
- Newer silicon revision with extended peripherals (vs PIC18F67J11-I/PT)
Notes de conception
The PIC18F67J10-I/PT has multiple VDD/VSS pairs (pins 8/7, 20/19, 30/29, 40/39, 50/49) and a separate AVDD/AVSS pair (pins 31/32). Per the PIC18F87J10 family datasheet, decouple each VDD pin with a 100 nF ceramic capacitor placed within 2 mm of the pin; add a shared 10 uF bulk capacitor near the package. Use a ferrite bead between digital VDD and analog AVDD to keep ADC noise below 1 LSB. The core runs from an internal regulator, so no separate VCAP pin is required on the J-series (unlike the PIC18F46J11/K22 families).
For the 64-pin TQFP package, route all I/O signals on outer layers only when possible and use a continuous ground plane on layer 2. The PIC18F87J10 family datasheet recommends a 4-layer PCB for designs that use the parallel slave port above 8 MHz. Keep crystal traces (OSC1/OSC2, pins 9/10) short and symmetric; place a guard ground ring around the crystal and its load capacitors. If using ICSP, route PGC/PGD (pins 27/28) with no series resistors; the MPLAB ICD tool provides its own pull-ups.
Three common pitfalls when migrating from PIC16 to PIC18F67J10: (1) The MCLR pin (pin 5) is input-only on this family - configure it as MCLR via CONFIG3H, not as RG5. (2) The J-series does not include data EEPROM; emulate it in Flash with a wear-leveling library or use a 25LCxx external SPI EEPROM. (3) The analog inputs AN8-AN13 (PORTF) are multiplexed with PORTF digital I/O - clear the corresponding TRISF bits and set PCFG bits before reading ADC. Always check the CONFIG registers at reset; the MPLAB code configurator will set sensible defaults but production firmware must explicitly lock the configuration words.
Estimated: at the maximum 40 MHz clock with all peripherals active (ADC, both MSSP, both EUSART, ECCP driving a MOSFET), core current is approximately 18 mA at 3.3V (~60 mW). The 64-pin TQFP has a typical theta_JA of 65 C/W on a 4-layer JEDEC test board, so the junction-to-ambient rise is about 4C - well below the 100C safe operating limit. No external heatsink is required. For high-IO current loads (e.g., driving 20 mA per pin), total package dissipation can reach 250 mW; verify with a thermal camera in production designs.
