Microchip PIC18F4685-I/P 8-Bit Flash MCU, DIP40

The Microchip PIC18F4685-I/P is a high-performance 8-bit Flash microcontroller from the PIC18 family, designed for demanding and power-sensitive applications. Featuring ECAN™ technology, a 10-bit A/D converter, and nanoWatt technology, this MCU delivers reliable operation with enhanced power management. The device includes an internal oscillator block that can generate two different clock signals, potentially eliminating the need for external oscillator circuits on the OSC1 or OSC2 pins, simplifying your design and reducing component count.

The PIC18F4685 supports serial programming while in the end application circuit, using just two lines for clock and data, plus three additional lines for power, ground, and programming voltage. In-Circuit Debug (ICD) is also supported via two pins, easing development and troubleshooting. With power-managed modes including Run, Idle, and Sleep, plus a flexible oscillator structure with a secondary oscillator using Timer1 at 32kHz and a fail-safe clock monitor, this microcontroller optimises energy usage without compromising performance.
