MICROCHIP PIC18F4520-I/P 8-Bit Flash Microcontroller DIP40

The MICROCHIP PIC18F4520-I/P is an Enhanced Flash Microcontroller featuring 10-bit Analogue-to-Digital conversion and advanced nanoWatt technology. This powerful 8-bit device is engineered for high-performance and power-sensitive applications, offering a suite of features designed to significantly reduce energy consumption during operation. Its robust RISC architecture delivers up to 10 MIPS performance and is optimised for C compilers, providing efficient processing power for complex embedded tasks.

A key innovation is the internal oscillator block, which generates multiple clock signals and can eliminate the need for external oscillator components on the OSC1 or OSC2 pins. This simplifies board design and reduces component count. The microcontroller is fully self-programmable under software control and supports In-Circuit Serial Programming (ICSP), allowing firmware updates via just two lines for data and clock while installed in the end application.
