Overview

The PIC18F25K40-I/SO is a high-performance 8-bit microcontroller featuring 32KB of Flash memory and 2KB of RAM, operating at speeds up to 64MHz. Part of the PIC18 K40 family, it integrates Core Independent Peripherals and XLP technology to minimize power consumption in battery-operated systems. This device is housed in a 28-pin SOIC package and includes a 10-bit ADC with Computation (ADC2) for automated signal analysis.

Why Choose This Part

This microcontroller offers Core Independent Peripherals (CIPs) which handle tasks in hardware to reduce CPU overhead and power draw. It features an optimized C compiler RISC architecture with a 31-level deep hardware stack and an extended instruction set for efficient code execution. The Peripheral Pin Select (PPS) functionality provides significant PCB routing flexibility by allowing I/O remapping.

Applications

Industrial Sensor Nodes
Utilizes the 10-bit ADC with Computation and Zero-Cross Detect for local signal processing and monitoring.
Battery-Powered Consumer Electronics
Leverages eXtreme Low-Power (XLP) technology and multiple sleep modes to extend battery life.
Capacitive Touch Interfaces
The integrated Hardware Capacitive Voltage Divider (CVD) simplifies the implementation of touch buttons and sliders.
System Supervisors
Acts as a secondary controller using the Windowed Watchdog Timer (WWDT) and Brown-out Reset to monitor main processor health.
