Microchip PIC18F24K42-I/SO 8-bit Microcontroller: Features and Applications
The Microchip PIC18F24K42-I/SO is a high-performance 8-bit microcontroller unit (MCU) from Microchip Technology's extensive PIC18 family. Housed in a 28-pin SOIC (Small Outline Integrated Circuit) package, this device is engineered to deliver a powerful combination of advanced peripherals, robust performance, and exceptional power efficiency, making it a versatile solution for a wide array of embedded control applications.
Key Features
At the core of the PIC18F24K42 lies a enhanced mid-range 8-bit CPU with a CIP (Core Independent Peripherals) architecture. This design allows peripherals to operate autonomously from the core, minimizing CPU intervention, reducing power consumption, and simplifying complex control logic.
A standout feature is its extensive memory configuration. It boasts 16 KB of Flash program memory, 1024 Bytes of Data SRAM, and 256 Bytes of Data EEPROM, providing ample space for both code and critical data storage. The MCU supports hardware-based Context Saving for faster and more deterministic interrupt handling.
Its analog capabilities are impressive, integrating a 12-bit Analog-to-Digital Converter (ADC) with Computation (ADC2). This peripheral can perform math operations on acquired data (like averaging, filtering, and comparison) while the CPU is in sleep mode, drastically improving power efficiency in sensor-based applications. It also includes on-chip comparators and a 5-bit Digital-to-Analog Converter (DAC).
For connectivity, the microcontroller is equipped with multiple serial communication modules, including EUSART (for UART), I2C, and SPI interfaces, enabling seamless communication with a vast ecosystem of sensors, displays, and other peripherals.
Furthermore, it includes advanced PWM (Pulse Width Modulation) modules for precise motor control and power conversion applications, along with hardware limit timers for added safety. Operating from 1.8V to 5.5V, it is suitable for both low-power battery-operated devices and more traditional 5V systems.
