PIC18F2620-E/SP 개요
A PIC microcontroller (MCU) is a compact programmable processor that integrates CPU core, Flash program memory, RAM, EEPROM, peripherals, and interrupt logic on a single silicon die. Within the Microchip taxonomy, the PIC18F2620 sits in the enhanced mid-range PIC18 family (8-bit RISC architecture with C-compiler-friendly instruction set), which itself is a sub-family of the broader PIC microcontroller hierarchy: PIC microcontroller -> 8-bit MCU -> embedded MCU -> microcontroller -> semiconductor IC.
Key features of the PIC18F2620 include ten 10-bit Analog-to-Digital Converter (ADC) channels, a 10 MIPS execution rate, an 8x8 single-cycle hardware multiplier, an internal oscillator block (31 kHz to 8 MHz) with PLL, a Fail-Safe Clock Monitor, and a Watchdog Timer with its own dedicated RC oscillator. The 25 bidirectional I/O pins support capacitive touch via the mTouch sensing solution, and the device includes multiple serial peripherals: Enhanced USART, MSSP (I2C/SPI), and up to two CCP/ECCP modules. NanoWatt power management offers Idle, Sleep, and several low-power modes for battery-friendly designs.
Architecturally, the PIC18F2620 uses a Harvard-class RISC core with 16-bit opcodes and 8-bit data path, dual-pointer stack with hardware context save, and a unified 16-bit instruction word that speeds single-cycle execution and simplifies C code generation. The integrated band-gap reference and self-programmable Flash support field firmware updates via ICSP, while the 256-byte EEPROM provides non-volatile parameter storage.
Typical applications include industrial automation controllers, automotive body/comfort ECUs, HVAC controls, medical patient-monitoring peripherals, low-cost sensor hubs, USB/serial bridges (when paired with the PIC18F2550 in the family), smart energy meters, and consumer appliances. The wide temperature range also enables outdoor signage, white-goods control boards, and instrumentation front-ends.
Design tip: the SPDIP package is preferred for breadboarding and legacy through-hole boards, but surface-mount variants (PIC18F2620-I/SO and PIC18F2620-I/SS) share the same pinout if you need to migrate to SMT. Always reserve a 6-pin ICSP header (PGD/PGC/MCLR/VSS/VDD/VPP) for in-circuit programming.

설계 노트
The PIC18F2620-E/SP operates from 4.2 V to 5.5 V; add a 100 nF decoupling capacitor within 5 mm of the VDD pin (pin 20) and a bulk 10 uF tantalum or aluminum polymer capacitor on the same rail. Use a ferrite bead if the 5 V rail shares a switching regulator with analog circuitry, and place a TVS diode (e.g. SMBJ5.0A) at the input of any field-wired connector. The MCLR/VPP pin (pin 1) needs a 10 kohm pull-up to VDD and a 100 nF cap to VSS to filter noise; without it, transient spikes can falsely reset the part in industrial environments.
Route the crystal traces (OSC1/OSC2, pins 8/9) as short as possible and keep ground pour at least 2 mm away from the crystal body. For HS mode (25 MHz), keep the crystal-to-pin traces under 10 mm and surround them with a ground guard ring. Place the ICSP header (PGD on pin 27, PGC on pin 26) on the board edge for production programming access, and label pin 1 clearly because the SPDIP notch orientation is sometimes reversed during assembly.
Three common pitfalls when migrating from PIC18F2525 firmware: (1) the PIC18F2620's larger Flash can shift the interrupt-vector table relative to bootloader code - verify the BOOT_ADDRESS fuses match the new code size; (2) the Analog input count is the same (10 channels) but channel mapping on PORTB pins differs slightly from the PIC18F4525/4620, so recheck ADC channel assignments; (3) do not apply > 5.5 V to any I/O pin or to VDD, even briefly, or the internal ESD clamp will forward-conduct and corrupt ADC readings. Use the LF variant (PIC18LF2620) if you need sub-5 V operation.
When using the PIC18F2620-E/SP's EUSART in RS-485 mode, isolate the TX/RX traces from the analog-input traces with a ground trace or guard ring to prevent switching noise from coupling into ADC samples. Place the RS-485 transceiver (e.g. MAX485) within 50 mm of the EUSART pins (RC6/RC7), and provide a 120 ohm termination at the cable-end node only. For I2C, use 4.7 kohm pull-ups on SCL/SDA (pins 13/14) at 100 kHz, or 2.2 kohm at 400 kHz Fast-Mode; weaker pull-ups cause rise-time violations on multi-slave buses.
The PIC18F2620-E/SP's quiescent current is approximately 1.6 mA active at 25 MHz, plus I/O drive current - in fully-loaded designs with all 25 outputs sourcing 20 mA, total current can exceed 500 mA. The SPDIP-28 package has a thermal resistance theta_JA of approximately 70 C/W in still air, so at 5.5 V x 0.5 A the part dissipates 2.75 W and the junction temperature rises 192 C above ambient - well above the 125 C limit. Derate I/O drive strength or limit active I/O count for high-temperature designs.
