PIC18F67K40-E/PT 개요
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, integrating CPU, volatile and non-volatile memory, peripherals and interrupt logic on one die. The PIC18 family uses an enhanced RISC Harvard architecture with a 16-bit instruction word, C-compiler friendly instruction set and on-chip peripherals such as Core Independent Peripherals (CIPs) that can execute logic, timing, PWM and communications without CPU intervention.
Key features of the PIC18F67K40 include eXtreme Low Power (XLP) technology with sub-uA sleep currents, 5 V tolerance on most digital I/O, an integrated 12-bit ADC with computation (ADC2), multiple UART/SPI/I2C peripherals, PWM, Complementary Waveform Generator (CWG), CRC/SCAN memory scan, Windowed Watchdog Timer (WWDT), and hardware touch (CTMU) capable I/O. The 64-pin TQFP exposes up to 60 I/O pins for ample user connectivity.
Architecturally, the PIC18F67K40 combines a 16-bit program-word Flash with 8-bit data path, a 31-level hardware stack, and on-chip instruction trace support via a debug interface. Internal PLL allows selectable system clocks up to 64 MHz while the XLP sleep mode retains RAM at <1 uA, making it ideal for battery powered sensor nodes.
Typical applications include industrial control panels, home appliance HMI, low-power IoT sensor nodes, automotive body and climate modules, and USB/HID peripherals using the on-chip FS USB transceiver. Designers frequently use the PIC18F67K40 in human-machine interface boards, motor control command front-ends and sensor aggregation hubs.
When designing in this part, leave the reserved pins (OSC1/OSC2/VDD/VSS pairs) on the 64-pin TQFP well-bypassed with 0.1 uF and 10 uF capacitors; the debug pins PGC/PGD should be brought to a 5-pin header for in-circuit serial programming. Pick PIC18F67K40-I/PT instead if your thermal environment does not exceed +85 °C.

설계 노트
Place a 0.1 uF decoupling capacitor within 5 mm of every VDD pin (11 and 32) and a single 10 uF bulk capacitor on the AVDD supply rail. For USB operation, the VUSB pin must be tied to VDD through a 10 uF capacitor and the D+/D- lines require 27 ohm series resistors per the USB specification to meet FS edge rates.
Keep the 64-pin TQFP footprint with 0.5 mm pitch and an exposed die pad for thermal dissipation. Route the PGC and PGD pins to a 5-pin ICSP header (MCLR, VDD, GND, PGC, PGD) placed at the board edge for in-circuit serial programming without removing the MCU. The exposed thermal pad must be soldered to a copper pour of at least 25 mm^2 for thermal relief at full 64 MHz operation.
Do not leave unused I/O pins floating - configure them as outputs driving low to eliminate shoot-through current in XLP sleep mode. The MCLR pin should be tied to VDD through a 10 kohm pull-up; do not leave it floating. A 100 nF capacitor on MCLR is recommended to suppress ESD-induced resets. Verify the PLL settings against the oscillator configuration bits to avoid lockup at startup.
Isolate the analog AVDD/VSS pair with a ferrite bead from the digital VDD/VSS supply to keep ADC2 measurements clean. Place the 12-bit ADC reference capacitor (0.1 uF) adjacent to the VREF+ pin. For CTMU touch applications, route touch electrodes with a guard ring tied to a quiet analog ground to maximize touch SNR.
