Overview

The PIC18F45K40-I/PT is a versatile 8-bit microcontroller featuring 32KB of Flash memory and a 64MHz internal oscillator. Part of the PIC18 'K40' family, it integrates eXtreme Low Power (XLP) technology with core independent peripherals to handle complex tasks with minimal CPU intervention. Its 44-pin TQFP package provides 36 I/O pins, making it suitable for applications requiring significant digital and analog interfacing.

Why Choose This Part

Engineers choose this part for its Peripheral Pin Select (PPS) feature, which simplifies PCB routing by allowing digital peripherals to be mapped to any I/O pin. The integration of 256 bytes of EEPROM provides reliable non-volatile storage for calibration data and user settings without requiring external components.

Applications

Industrial Control Systems
Utilizing the 10-bit ADC with computation and multiple timers for monitoring and controlling factory floor equipment.
Automotive Body Electronics
Managing interior lighting, door locks, and window controls via the integrated LINbus and EUSART interfaces.
Handheld Battery-Powered Devices
Leveraging XLP technology and Peripheral Module Disable (PMD) to extend battery life in portable instrumentation.
Sensor Integration Hubs
Using Peripheral Pin Select (PPS) to flexibly map I2C, SPI, and UART interfaces to specific pins for multi-sensor data collection.

Getting Started

Development is primarily supported through Microchip MPLAB X IDE and the XC8 C Compiler. For rapid prototyping, the Curiosity High Pin Count (HPC) Development Board is the recommended hardware platform, while the MPLAB PICkit 4 or ICD 4 serve as the standard in-circuit debugger and programmer.
