MICROCHIP PIC18F4620 8-Bit Flash Microcontroller, 40MHz, DIP40

The MICROCHIP PIC18F4620-I/P is an enhanced 8-bit Flash microcontroller built on a high-performance, C compiler-optimised RISC architecture. It integrates advanced features like 10-bit analogue-to-digital conversion and proprietary nanoWatt technology for exceptional power management across a wide range of embedded applications.

This versatile device offers seven distinct operating modes, including Run, Idle, and Sleep, allowing for selective power conservation in resource-sensitive designs. Its innovative power-saving technology enables impressively low current consumption, with typical idle currents as low as 5.8μA and sleep mode currents down to 0.1μA. The microcontroller supports ten different oscillator options, including an internal oscillator ranging from 31kHz to 8MHz with a 4x Phase-Locked Loop (PLL), providing developers with extensive flexibility for their hardware design.

Key Features & Architecture

Employing a Harvard architecture, the PIC18F4620 uses separate busses for program and data memory, enabling concurrent access for improved performance. It includes a substantial 64KB of Flash program memory and 3.9KB of RAM. The integrated peripheral set is comprehensive, featuring a 10-bit Analogue-to-Digital Converter (ADC) with 13 channels capable of 100k samples per second, an LCD driver module capable of driving 48 segments and 4 commons, and multiple communication interfaces including EUSART (with LIN bus support), SPI, I²C, and PSP.

Reliability & System Protection

Designed for robust operation, the microcontroller includes several critical system protection features. These include a programmable brown-out-reset module, a programmable low-voltage detection module, a fail-safe clock monitor for safe shutdown during clock failure, and a watchdog timer with a separate RC oscillator. It operates within a supply voltage range of 4.2V to 5.5V and across a broad temperature range from -40°C to
