Its combination of nanoWatt technology and enhanced core features makes it a compelling choice for embedded designers across consumer, industrial, and automotive domains.
Core Architecture and Performance
At its heart lies an enhanced PIC18 architecture with a 16-bit instruction set. The core operates at speeds up to 64 MHz, delivering a performance of 16 MIPS (Million Instructions Per Second). This balance of speed and efficiency is central to its design, enabling it to handle complex control algorithms and real-time processing tasks effectively. The core is further augmented with a hardware multiplier, accelerating mathematical computations crucial for data processing applications.
Memory Configuration
The PIC18F24K20T-I/ML is equipped with a substantial and flexible memory subsystem. It features 16 KB of self-read/write capable Flash program memory, which allows for robust bootloader functionality and firmware updates in the field. For data handling, it incorporates 768 Bytes of RAM and 256 Bytes of EEPROM. The EEPROM provides critical non-volatile storage for application parameters, ensuring data retention even during power cycles.
Integrated Peripherals and Connectivity
This microcontroller distinguishes itself with a powerful array of on-chip peripherals, reducing system component count and overall design complexity.
Analog Capabilities: It includes a 10-bit Analog-to-Digital Converter (ADC) with up to 13 channels, facilitating precise measurement of multiple analog sensors. It also features a comparator and voltage reference module for advanced analog signal conditioning.
Communication Interfaces: For system connectivity, it offers multiple serial communication protocols, including EUSART (for RS-232/RS-485), SPI, and I2C™. These interfaces are essential for communicating with sensors, displays, memory chips, and other peripherals.
Timing and Control: The device is packed with timers, including 4x 8-bit and 3x 16-bit timers/counters.
