PIC18F67J50-I/PT - 8-bit 48MHz 128KB Flash USB MCU | Microchip
MPN: PIC18F67J50-I/PT ✓ פעילPIC18F67J50-I/PT סקירה
An MCU (microcontroller unit) is a single-chip computer containing a CPU, non-volatile program memory, working RAM, and a rich set of peripherals such as timers, ADCs, communication interfaces, and I/O. Within the Microchip taxonomy, the PIC18 family sits above the baseline PIC16 line and below the PIC24/dsPIC33 16-bit families, using an enhanced 8-bit RISC core with hardware multiplier and C-friendly architecture.
Key features include a 10-channel 10-bit ADC, two enhanced USARTs with LIN support, one MI2C and one SPI port rated up to 10 Mbit/s, an integrated Full-Speed USB 2.0 transceiver (12 Mbit/s) that eliminates external PHY circuitry, four timers, and nanoWatt power management with multiple idle and sleep modes. The 64-pin TQFP exposes 50+ general-purpose I/O pins, suiting applications with rich keypad, LCD, or sensor interfaces.
The PIC18F67J50-I/PT architecture combines a 16-bit wide instruction path with an 8-bit datapath, providing deterministic interrupt latency and a single-cycle hardware multiplier. Internal oscillator calibration plus Fail-Safe Clock Monitor make the device robust against main crystal failures in industrial environments. The integrated USB SIE handles most protocol overhead in hardware, freeing CPU cycles for application logic.
Typical applications include USB HID/CDC peripherals such as custom keyboards, mice, data loggers and industrial sensors, embedded web servers with TCP/IP stacks, automotive LIN slave nodes, low-cost instrumentation, and battery-powered consumer devices leveraging nanoWatt modes. The combination of USB, ample RAM for USB descriptors and TCP/IP buffers, and 128 KB Flash for protocol stacks makes this MCU a compact one-chip solution.
When designing with this part, note that core supply VDD must be 2.0-3.6V while I/O pins are 5V-tolerant only on selected pins; a 3.3V LDO or switching regulator is normally used. Decouple VDD/VUSB/VUSB3V3 with 100 nF plus 4.7 uF bulk caps close to the pins, route D+/D- as a 90-ohm differential pair, and respect the USB suspend current budget to benefit from nanoWatt idle modes.

Embedded Web Server / TCP-IP Edge Devices
For embedded web servers and TCP/IP-connected edge devices, the PIC18F67J50-I/PT offers 128 KB Flash to hold a small IPv4 stack plus HTML assets, and 3,936 bytes RAM to buffer incoming TCP segments. Its 48 MHz core runs a 12 MIPS pipeline that executes the network stack with low jitter. The integrated USB can simultaneously expose a CDC debug channel, while SPI up to 10 Mbit/s drives an Ethernet controller such as ENC28J60 for full TCP/IP connectivity without external PHY complexity.
מומלץ
Automotive LIN Slave Nodes
The PIC18F67J50-I/PT's two EUSARTs are LIN-capable, making it a strong fit for automotive body electronics and LIN slave nodes such as mirror controllers, seat adjusters, or HVAC flap drivers. Its 2.0V-3.6V supply suits 12V automotive rails after LDO regulation. With 128 KB Flash the MCU has ample room for LIN 2.x stacks, NMIs for fault handling, and PWM-driven actuator loops. Industrial -40 C to +85 C rating matches under-hood and cabin environments.
מומלץ
Industrial Sensors and Data Acquisition
The PIC18F67J50-I/PT integrates a 10-channel 10-bit ADC that scans multiple analog sensors in industrial data acquisition systems. Combined with MI2C and SPI ports, the MCU aggregates readings from external sensors, op-amps, and digipots while streaming results via USB or RS-485. The 48 MHz core provides deterministic ADC-to-output latency critical for control loops, while nanoWatt idle modes reduce sleep current to support battery or energy-harvested sensor nodes.
מומלץ
Battery-Powered Consumer Devices
For battery-powered consumer devices, the PIC18F67J50-I/PT's nanoWatt technology provides multiple low-power modes - Idle, Sleep, and deep Sleep - that drop quiescent current to microamp levels. The 2.0V minimum supply extends usable life on partially discharged Li-ion cells or 2x AA packs. With integrated USB the MCU handles charging protocol or data sync without an extra interface chip, and 128 KB Flash accommodates BLE via SPI radio plus app logic in one part.
מומלץ
Low-Cost Test and Measurement Instrumentation
The PIC18F67J50-I/PT fits cost-sensitive bench instruments such as USB voltmeters, logic analyzers, and signal generators. Its 10-bit ADC plus 50+ GPIO can sample external signals while the integrated USB streams data to host software at 12 Mbit/s. With 128 KB Flash the MCU can hold protocol interpreters for SCPI over CDC, simple FFT algorithms, or PC-side GUI drivers, eliminating the cost of a dedicated instrument controller and shortening design cycle.
מומלץ
Display and Keypad Interface Boards
For human-machine interfaces combining character or graphic LCDs with matrix keypads, the PIC18F67J50-I/PT's 50+ GPIO are sufficient to drive a 4x20 character LCD plus 4x5 keypad without external I/O expanders. SPI up to 10 Mbit/s can drive small TFT displays, while the USB interface accepts configuration uploads from a host PC. nanoWatt modes let the device sleep between user interactions, minimizing idle power in wall-powered or battery HMI panels.

הערות תכנון
The PIC18F67J50-I/PT core VDD must be supplied from 2.0 V to 3.6 V while the integrated USB transceiver derives 3.3 V internally via an on-chip regulator. Place a 100 nF ceramic decoupling cap on each VDD pin (7, 20, 50, 60) within 5 mm of the pin, and add a single 4.7 uF bulk capacitor on the main VDD rail. The VUSB3V3 pin (6) requires its own 220 nF decoupling cap; do not load this pin with external circuitry as it powers only the USB transceiver.
USB differential pair routing is critical - route D+ (pin 9) and D- (pin 10) as a 90-ohm differential pair with controlled impedance, matching trace lengths within 150 mil, and keeping them away from switching regulators and clocks. Place the 27-ohm series termination resistors close to the MCU side, not the connector. Use a common ground plane under the USB traces; do not split the ground. This layout minimizes EMI and ensures USB compliance.
Several I/O pins (RB0-RB3, RC4/RC5) on the PIC18F67J50-I/PT are NOT 5V-tolerant when the device is running at 2.0 V; review the datasheet DC characteristics table before connecting to 5V logic. A common mistake is leaving MCLR floating - tie it to VDD via a 10 kohm resistor and place a 100 nF cap on MCLR only if in-circuit debugging is used. Also ensure unused I/O pins are configured as outputs low or inputs with internal weak pull-ups enabled to minimize current draw.
The 64-pin TQFP (PT) package has a typical theta_JA of around 40 C/W on a 2-layer JEDEC test board, giving roughly 0.025 C/W per copper pour. At full 48 MHz operation with all peripherals active, total power dissipation stays well under 200 mW even at 3.6 V, so junction temperature rise above ambient is approximately 8 C - well within the +85 C industrial limit. For thermally enclosed designs, add 1 square inch of copper pour to the VSS/VDD pins.
When using the SPI port at the maximum 10 Mbit/s rate with the PIC18F67J50-I/PT, keep SPI traces short and series-terminate the SCK line with 33-ohm if the trace exceeds 50 mm. Use the MI2C peripheral instead of bit-banging for I2C to avoid timing violations; enable the internal weak pull-ups only for low-speed (100 kHz) operation. For EUSART LIN mode, ensure the baud-rate error stays below +/- 2% to meet LIN 2.x compliance.
