Microchip PIC18F4685 8-Bit Flash Microcontroller TQFP44

Microchip PIC18F4685 is an 8-bit Flash microcontroller in a TQFP44 package, offering 96 KB of program memory and integrated ECAN technology for high-performance and power-sensitive applications.

Overview

The Microchip PIC18F4685-I/PT is an Enhanced Flash microcontroller that integrates ECAN technology, a 10-bit A/D converter and nanoWatt technology. Its robust feature set and low-power capabilities make it well suited to a wide range of industrial and embedded applications.

The internal oscillator block generates two distinct clock signals, which can potentially eliminate the need for external oscillator circuits on the OSC1 or OSC2 pins. The device supports serial programming within the end application circuit using two lines for clock and data, along with three additional lines for power, ground and programming voltage. Power-managed modes include Run, Idle and Sleep, while the flexible oscillator structure includes a secondary oscillator using Timer1 at 32 kHz and a fail-safe clock monitor.
