PIC18LF6310T-I/PT Übersicht
An 8-bit microcontroller (MCU) is a small computer-on-a-chip integrating a CPU, RAM, Flash program memory, EEPROM, timers, ADCs, and serial peripherals on a single die. Within the broader taxonomy, the PIC18LF6310 sits under: 8-bit MCU -> PIC18 family -> PIC18F6xxx 'high-pin-count' sub-family -> embedded microcontroller -> semiconductor. This hierarchy matters for designers selecting peripherals and instruction-set compatibility: PIC18 cores use an enhanced 16-bit instruction set with 8-bit data path, supporting C and assembly development under MPLAB X IDE and the XC8 compiler.
Key features of the PIC18LF6310T-I/PT include 8KB self-programmable Flash with read-while-write capability, an internal 10-bit ADC, multiple 16-bit timers, enhanced CCP, USART, SPI, and I2C peripherals, an on-chip 31 kHz low-power oscillator, and nanoWatt XLP power-management modes for battery-powered designs. Industrial temperature range (-40C to +85C) and the 64-TQFP footprint make it suitable for space-constrained but I/O-rich applications.
The architecture is a Harvard RISC core with 16-bit instructions and 8-bit data, single-cycle multiplication, and hardware multiply/divide support. Flash endurance is rated at 100K erase/write cycles, EEPROM at 1M cycles, and retention is specified at 40 years minimum. The nanoWatt XLP variants deliver idle currents below 1 uA, enabling multi-year battery life in duty-cycled sensor products.
Typical applications include industrial control panels, white-goods user interfaces, HVAC thermostats, low-end medical instruments, automotive body and lighting subsystems, and battery-powered sensor hubs. The wide peripheral set and ample I/O also suit USB-less human-interface controllers, RFID readers, and motor-control BLDC drivers.
When designing with this MCU, ensure the MCLR pin is correctly pulled-up, the Vcore decoupling (10uF + 100nF) is placed within 1 cm of the supply pins, and oscillator layout follows the recommended ground-fence pattern from the PIC18F6310 datasheet (DS39639 family reference).

Typische Anwendungen
PIC18LF6310T-I/PT ist geeignet für 7 Anwendungs: Industrial Control Panel HMI, HVAC Thermostat / Building Sensor Hub, White-Goods / Home Appliance Control, Automotive Body & Lighting ECU, Battery-Powered Sensor Node, BLDC / Small Motor Control, Low-End Medical Instrument Controller.
Industrial Control Panel HMI
The PIC18LF6310T-I/PT's 64-pin TQFP delivers 50+ usable I/O lines for keypad scanning, seven-segment or character-LCD drive, status LEDs, and relay outputs typical of industrial HMI panels. The 8 KB Flash accommodates a full state-machine plus menu library, while 768 bytes of RAM handles key debounce buffers and display refresh. The 40 MHz (10 MIPS) core runs a 4 ms keypad scan with negligible CPU loading. NanoWatt XLP sleep currents below 1 uA let the panel survive brown-outs without external RTC. Place the MCU on a 4-layer board with Vcore decoupling within 1 cm of pins 20-32 and a ground-fenced oscillator.
Empfohlen
HVAC Thermostat / Building Sensor Hub
The PIC18LF6310T-I/PT's LF core runs from a single 3.3V rail - ideal for thermostat and sensor-hub applications drawing power from 2x AA batteries or a 24VAC-derived DC rail. The 10-bit ADC with multiple channels reads thermistor, humidity, and occupancy sensors simultaneously; USART and I2C connect to a Zigbee or LoRa daughter module. NanoWatt XLP sleep draws ~100 nA, enabling 5+ year battery life in duty-cycled sensor mode. The 64-pin TQFP footprint keeps board area to ~10x10 mm. Use the internal 31 kHz LF oscillator for RTC tick to minimize wake energy.
Empfohlen
White-Goods / Home Appliance Control
Washing machines, dishwashers, and ovens need a robust MCU that can drive triac-gated AC loads, read rotary encoders, and run a safety-watchdog state machine. The PIC18LF6310T-I/PT offers industrial -40C to +85C operation, 64 I/O lines for triac firing, and 8 KB Flash to host the cycle algorithm plus fault logging. The 40 MHz core executes a 1 ms triac zero-cross routine with margin. Internal EEPROM emulation in Flash stores cycle counters and fault codes across power cycles. Place the MCU physically away from the triac bridge with opto-isolated gate drive.
Empfohlen
Automotive Body & Lighting ECU
Interior lighting, mirror controllers, and accessory modules often use a 3.3V PIC18LF6310T-I/PT for cost reasons. The LF core handles CAN-LIN bus fault recovery (when paired with an external transceiver) and PWM dimming of LED strings at 1 kHz with hardware CCP. Eight KB Flash holds the lighting fade curve library and the fault diagnostic trouble codes. The 64-TQFP gives 50+ I/O for LED driver enable lines. Note: this is NOT an AEC-Q100 part - for under-hood or safety-critical ECUs use a Q-qualified part instead.
Empfohlen
Battery-Powered Sensor Node
The PIC18LF6310T-I/PT's nanoWatt XLP modes let a sensor node wake every 5 seconds, take an ADC sample, transmit via SPI radio, and return to sleep - all within 10 ms - drawing average current below 50 uA from a CR2032 cell. The LF 2.0V minimum Vdd supports single-cell alkaline designs down to end-of-life voltage. 8 KB Flash hosts the radio driver and sensor compensation tables. The 64-TQFP offers ample GPIO for multi-sensor boards. A 31 kHz LF oscillator provides the wake tick, while the 8 MHz internal oscillator handles active-mode processing.
Empfohlen
BLDC / Small Motor Control
Small BLDC fans, pumps, and e-bike auxiliary motors can be driven by the PIC18LF6310T-I/PT using its enhanced CCP and 16-bit timer for hardware commutation. The 40 MHz core executes a 6-step trapezoidal commutation loop in < 5 us, leaving margin for current sensing and fault response. 8 KB Flash stores the startup ramp profile, while 768 B RAM holds the speed PI controller state. The 64-TQFP gives independent PWM channels for the three half-bridges plus brake and direction signals. Place shunt resistors on the source side with op-amp conditioning to the ADC.
Empfohlen
Low-End Medical Instrument Controller
Bedside monitors, infusion pump keypads, and point-of-care devices that do not require IEC 60730 class B software can use the PIC18LF6310T-I/PT as the main user-interface controller. The 8 KB Flash holds the menu and alarm logic, while the 10-bit ADC reads battery voltage and patient-input analog signals. The 64-pin TQFP fits a compact front-panel board. NanoWatt XLP idle extends battery runtime on portable carts. Designers targeting FDA-class II or higher should add a watchdog (e.g. MCP1316) and consider a Q-qualified or medical-specific MCU.

Wichtigste Unterscheidungsmerkmale
- 64-pin TQFP with full PIC18 peripheral set (vs. PIC18LF46K22T-I/PT)
- Low-voltage LF core for battery designs (vs. PIC18F6310T-I/PT)
- Tape-and-reel suffix for SMT production (vs. PIC18LF6310-I/PT)
Designhinweise
The PIC18LF6310T-I/PT requires decoupling within 1 cm of every VDD/VSS pin pair (pins 11/10, 24/23, 34/33, 44/43, 54/53). Use a 100 nF X7R ceramic per pair plus a single 10 uF tantalum or ceramic bulk cap on the main 3.3V rail. A separate AVDD/AVSS pair (pins 61/60) feeds the analog domain and should have its own 100 nF + 10 uF filter. Estimated total bulk capacitance for a clean LF core: 5x 100 nF + 1x 10 uF. Follow the layout pattern in the PIC18F6310 datasheet (DS39639) section 2.0 'Guidelines for Getting Started with PIC18'.
The 64-TQFP (10x10 mm) package has 0.5 mm pitch - use 0.25 mm trace/space with a 4-layer stack-up (signal/GND/power/signal) to escape the inner pins. Place the crystal or resonator within 5 mm of pins 13-14 (OSC1/OSC2) and surround the oscillator with a ground fence tied to the analog ground. Keep high-speed digital lines (PWM, SPI clocks) at least 5 mm away from the analog AVDD/AVSS pair. The exposed thermal pad on TQFP-64 is NOT present on this package - thermal dissipation is through the 64 perimeter leads only.
Three common PIC18LF6310T-I/PT design mistakes: (1) Forgetting to pull MCLR (pin 1) high through a 10 kOhm resistor - the part will not run otherwise; (2) Configuring the LF device at 5V - the LF core is rated 2.0V to 3.3V only, exceeding 3.6V will damage the silicon; (3) Driving a crystal without loading capacitors - use 22 pF to GND from each OSC pin per the crystal datasheet. Configuration word settings (4 MHz vs 8 MHz internal oscillator, WDT enable) must be reviewed against the actual hardware for first-time bring-up.
For designs that switch the 64-pin TQFP I/O at high frequency (e.g. SPI > 10 MHz or PWM > 50 kHz), series-terminate each output with 33 ohm to dampen reflections on long traces (> 50 mm). Keep the I/O supply (VDD pins 11/24/34/44/54) star-routed to a common ferrite bead from the 3.3V rail. The analog AVSS pin (60) MUST be tied to the same ground potential as VSS pins; floating AVSS causes ADC channel crosstalk and reference drift up to 5 LSB.
