PIC18F6310T-I/PT - 8-bit PIC MCU, 8KB Flash, 64-Pin TQFP | Microchip
MPN: PIC18F6310T-I/PT ✓ Hoạt độngPIC18F6310T-I/PT Tóm tắt
An 8-bit microcontroller (MCU) is a programmable integrated circuit that combines a CPU, memory (Flash for program storage, SRAM for data), and peripheral interfaces on a single die. The PIC18F family sits within the broader PIC (Peripheral Interface Controller) architecture and traces its hierarchy to microcontroller -> embedded processor -> semiconductor device. PIC18F MCUs use a Harvard RISC architecture with separate program and data buses, and they execute most instructions in a single 4-cycle clock period (one instruction cycle per 4 oscillator cycles).
Key features include 8 KB (4K x 16) of self-programmable Flash, 768 bytes of data RAM, 256 bytes of EEPROM, and a 10-bit Analog-to-Digital Converter (ADC) with up to 12 input channels. Communication peripherals include Enhanced USART, MSSP (SPI/I2C), and Parallel Slave Port. The device supports 54 digital I/O pins with high-current sink/source capability and offers multiple power-managed modes for low-power operation.
The PIC18F6310 integrates advanced peripherals such as a 16-bit Capture/Compare/PWM (CCP) module, multiple timers, and a Hardware RTCC for real-time clock functions. These are designed for human-interface and control applications where deterministic real-time response is critical. The 64-pin TQFP package provides ample I/O access in a 10 x 10 mm outline suitable for moderately dense PCB designs.
Typical applications include industrial manufacturing equipment, instrumentation and monitoring, data acquisition systems, power conditioning, environmental monitoring, telecom infrastructure, and consumer electronics. The wide peripheral set also makes it suitable for HVAC controls, security panels, and display drivers.
When designing with this MCU, ensure VDD decoupling uses 100 nF and 10 uF capacitors placed close to the supply pins. Configure the configuration bits (fuses) for oscillator source, watchdog timer, and code protection before programming. The Industrial temperature grade allows deployment in uncontrolled thermal environments.

PIC18F6310T-I/PT phù hợp cho 6 Áp dụngs: Industrial Manufacturing Equipment Control, Data Acquisition and Instrumentation, Power Conditioning and Energy Monitoring, Environmental Monitoring and HVAC Control, Telecom Infrastructure Peripherals, Consumer Appliance Control Boards.
Industrial Manufacturing Equipment Control
The PIC18F6310T-I/PT fits industrial machinery controllers thanks to its 10 MIPS throughput, 54 GPIO lines, and 10-bit ADC for sensor interfacing. A typical CNC auxiliary board uses the MCU to drive stepper direction signals, read limit-switch inputs, and poll analog load sensors at 4.2-5.5 V. Compared with discrete logic, the integrated EUSART and SPI simplify wiring to motor-driver ICs like the DRV8711, while the 8 KB Flash comfortably fits state-machine firmware.

Environmental Monitoring and HVAC Control
The PIC18F6310T-I/PT is well suited to multi-sensor HVAC and building-automation panels, where its 12 ADC inputs read temperature/humidity probes and its EUSART links to Modbus or BACnet transceivers. The 10 MIPS throughput executes PID loops with 1 ms loop time, and the CCP drives TRIAC phase-control outputs for damper actuators. Industrial-grade temperature tolerance ensures reliable operation in unconditioned plant rooms.

Ghi chú thiết kế
Decouple every VDD/VSS pair with a 100 nF ceramic capacitor placed within 5 mm of the IC pins; add a single 10 uF bulk capacitor near the package. The PIC18F6310T-I/PT has six VDD/VSS pairs distributed around the TQFP-64, and skipping any of them can cause brown-out resets or ADC noise. Estimated: based on the package pin map, six bypass caps provide the recommended ground-return paths for the digital core and I/O banks.
Route the ICSP lines PGC (RB6) and PGD (RB7) directly to a 6-pin header with no series resistors in production circuits. Keep the trace length below 50 mm to ensure reliable in-circuit programming at 5 V. Place the MCLR pull-up (typically 10 kOhm) close to the MCU and add a 100 nF capacitor to ground for noise immunity, especially in motor-control or relay-driven boards.
Configure the configuration bits (CONFIG1H-4L) before programming: select HS or XT oscillator mode for 40 MHz crystals, disable the watchdog unless required, and enable code protection only after firmware is finalized. The CCP1 pin (RC2) is multiplexed; if used for analog or GPIO, remap CCP1 output to a different pin via the PPS-equivalent register set on compatible PIC18F variants. Failure to set the BOR (Brown-Out Reset) voltage correctly can lead to unreliable startup on slowly rising supplies.
When using the 10-bit ADC, add a 100 nF bypass on AVdd and a small RC filter (1 kOhm + 100 nF) on each analog input to reduce digital switching noise coupling. Avoid routing ADC traces next to high-frequency signals (SPI clock, PWM outputs). Estimated: 1 kOhm source impedance plus 100 nF yields a 1.6 kHz low-pass cutoff, suitable for 100 Hz-1 kHz sensor sampling without significant attenuation.
