PIC18F67J10T-I/PT Overview
Key features include 128 KB Flash (64K x 16), 3936 bytes of RAM, 40 MHz maximum clock with 200 ns instruction cycle (10 MIPS at 40 MHz when using a 4x PLL), 10-bit ADC with up to 11 channels, nanoWatt Technology power management modes, and two comparators. The wide 2.0 V to 3.6 V core VDD range (with 4.2 V to 5.5 V noted in some datasheet rows; the canonical PIC18F67J10 family is 2.0-3.6 V) supports both battery-powered and regulated industrial rails. The 64-pin TQFP footprint is one of the most widely supported packages for the PIC18F family, simplifying layout, hand-rework, and socket compatibility.
The PIC18F67J10 architecture uses an enhanced Harvard RISC core with 16-bit-wide instructions and 8-bit-wide data path, providing deterministic timing for interrupt-driven and control-loop applications. The nanoWatt Technology dynamic power management block enables idle, sleep, and run-time switching to optimize current consumption in low-duty-cycle designs. CIP (Core Independent Peripherals) such as the Enhanced USART, MSSP (Master Synchronous Serial Port supporting I2C and SPI), and PWM modules operate without CPU intervention after configuration, freeing the core for application logic. The 40 MHz internal oscillator option further reduces BOM count.
Typical applications include industrial control (sensor hubs, PLC expansion modules), automotive body and chassis subsystems (LIN nodes, lighting controllers), consumer appliances (HVAC controls, washing-machine front panels), USB/serial bridging, and embedded HMI. The combination of large Flash, dual serial ports, and 54 I/O lines enables complex protocol stacks and rich user interfaces on a single MCU.
When designing with this part, choose the VDD range that matches your supply rail (2.0-3.6 V core VDD), use the on-chip 8 MHz internal oscillator for BOM-cost savings, and verify the pinout against the 64-pin TQFP diagram in the PIC18F67J10 family datasheet before PCB layout.

Typical Applications
PIC18F67J10T-I/PT is suitable for 6 applications: Industrial Sensor Hub & PLC Expansion I/O, Automotive Body Electronics & LIN Nodes, Consumer Appliance Control Boards, USB-to-Serial Bridge & Embedded Host Interface, Embedded HMI Front Panels, Motor Control & PWM Fan Drivers.
Industrial Sensor Hub & PLC Expansion I/O
The PIC18F67J10T-I/PT's 54 I/O pins and dual UART (with LIN support on USART1) make it ideal for industrial sensor hubs and PLC expansion modules that aggregate multiple analog and digital inputs. The 10-bit ADC handles typical 0-10 V or 4-20 mA sensor conditioning with internal reference, while the 128 KB Flash accommodates Modbus RTU, IO-Link, or vendor-specific protocol stacks. Its -40C to +85C industrial temperature grade ensures reliable operation in factory-floor enclosures, and nanoWatt Technology sleep modes cut standby current for remotely mounted I/O tiles. The 64-pin TQFP footprint is widely supported by low-cost carrier boards, simplifying field replacement.
Recommended
Automotive Body Electronics & LIN Nodes
PIC18F67J10T-I/PT suits LIN-connected automotive body and chassis subsystems such as mirror controllers, seat adjusters, HVAC dampers, and lighting clusters. The two enhanced USARTs both support LIN 1.3/2.0 master and slave modes with automatic baud-rate detection, offloading the core from bit-banging. Industrial-grade -40C to +85C operation tolerates cabin and engine-bay thermal stress, while 128 KB Flash holds the LIN stack plus application logic. The 64-pin TQFP-10x10 is the standard Microchip automotive body-electronics footprint, sharing PCB layout across LIN sub-modules. For AEC-Q100 automotive-qualified replacements, designers can drop in PIC18F66K22-I/PT or PIC18F46K80-I/PT with firmware porting.
Recommended
Consumer Appliance Control Boards
Washing machines, dishwashers, ovens, and HVAC indoor units benefit from PIC18F67J10T-I/PT's combination of large Flash (for multi-language UI and motor-control state machines), 54 I/O lines (for keypad scanning, LED/LCD drive, triac firing), and 2x UART (for diagnostic ports and BLE/Wi-Fi module host links). The MSSP peripheral supports I2C or SPI to interface with sensor front-ends (temperature, humidity, pressure) and to program EEPROM for run-time parameter storage. Its 2.0 V to 3.6 V core VDD is well-matched to 3.3 V regulated rails, and nanoWatt Technology idle modes trim standby power to meet energy-star requirements. The 64-pin TQFP is hand-rework friendly, simplifying warranty repair depots.
Recommended
USB-to-Serial Bridge & Embedded Host Interface
PIC18F67J10T-I/PT can act as a USB-to-UART/SPI/I2C bridge between a host PC and legacy serial peripherals, offloading enumeration and bulk-transfer handling onto the PIC18 core while exposing MSSP and USART channels downstream. The 128 KB Flash comfortably fits USB CDC, HID, or vendor-class firmware plus command interpreters, and the 3936 bytes of RAM buffer small HID report descriptors or CDC line-state buffers. The 64-pin TQFP-10x10 provides generous I/O for status LEDs and external interface muxing. For designs requiring native USB, the PIC18F66J50T-I/PT (same package, includes USB Full-Speed peripheral) is a drop-in alternative.
Recommended
Embedded HMI Front Panels
The PIC18F67J10T-I/PT drives character LCDs, small TFTs, segmented LED displays, and capacitive touch keypads in appliance and industrial HMI front panels. Its 54 I/O pins support parallel LCD data buses, LED matrix scanning, and PWM backlight control through the CCP/ECCP modules. 128 KB Flash fits rich state-machine UI logic plus bootloader for field firmware updates over UART or I2C. The industrial -40C to +85C rating keeps the display module functional across factory and warehouse environments. nanoWatt Technology sleep modes drop below 1 uA when the user is idle, extending battery life in portable HMI scanners.
Recommended
Motor Control & PWM Fan Drivers
PIC18F67J10T-I/PT's multiple CCP/ECCP modules deliver PWM outputs suitable for brushed DC, stepper, or BLDC commutation in low-power motor and fan driver boards. The 10-bit ADC samples back-EMF or current-sense feedback, while 128 KB Flash holds field-oriented control or trapezoidal commutation tables. The 64-pin TQFP-10x10 leaves headroom for gate-driver enable signals and fault inputs, and its 2.0 V to 3.6 V VDD simplifies 3.3 V gate driver interfacing. For higher-voltage (5 V) drive, the K-series PIC18F46K22T-I/PT (same package) is an alternative with 5 V tolerance.

Key Differentiators
- Highest Flash density in the TQFP-64 PIC18J family (vs PIC18F66J15T-I/PT)
- Native LIN support on dual USARTs (vs PIC18F66J50T-I/PT)
- Industrial -40C to +85C grade standard (vs PIC18F6720-I/PT)
Design Notes
The PIC18F67J10T-I/PT has a VDDCORE pin (pin 41) that must be decoupled with a low-ESR 1 uF ceramic capacitor to ground, placed within 5 mm of the pin. The internal 1.8 V regulator powers the core logic; do not load VDDCORE externally. Bulk VDD rails should each have a 100 nF ceramic plus 4.7 uF tantalum/ceramic capacitor for stability across load transients, especially when waking from sleep mode at high slew rates.
The PIC18F67J10 is a 3.3 V part (VDD 2.0 V to 3.6 V); applying 5 V to VDD will damage the MCU. For designs migrating from a 5 V PIC18F4520 or PIC18F6720, use a 3.3 V LDO and verify all peripherals are 3.3 V tolerant. The MCLR reset pin (pin 57) requires a 10 kohm pull-up to VDD; do not leave it floating or the device may intermittently enter reset during EMI events.
Route the ICSP signals PGC (RB6, pin 35) and PGD (RB7, pin 36) as short traces with ground guarding, and keep them away from switching power or PWM outputs to prevent programming/debug failures. Place the 40 MHz external crystal (if used) within 5 mm of OSC1/OSC2 (RA6/RA7) with grounded guard traces; the on-chip 8 MHz internal oscillator is generally adequate for non-USB designs and removes BOM cost.
Estimated: at -40C to +85C ambient, the TQFP-64 package theta_JA is approximately 50 C/W per typical Microchip thermal data. At full CPU (40 MHz, all peripherals active) the core dissipation is ~150 mW, producing ~7.5C temperature rise above ambient - well within the 85C industrial ceiling. No external heatsink is required for typical duty cycles.
Compliance Information
Industrial temperature grade only (-40C to +85C); -E suffix variants extend to +125C but are not AEC-Q100 qualified. RoHS/REACH compliance per Microchip product environmental documentation.
