Microchip PIC18F26K40-I/SO 8-bit Microcontroller Technical Overview and Application Guide
The Microchip PIC18F26K40-I/SO is a high-performance 8-bit microcontroller built on PIC18 architecture, designed to deliver a powerful combination of processing capability, energy efficiency, and peripheral integration. It is an ideal solution for a wide range of embedded control applications in automotive, industrial, consumer, and IoT domains.
Housed in a 28-pin SOIC (Small Outline Integrated Circuit) package, this microcontroller is engineered for space-constrained applications. At its core lies an enhanced mid-range CPU capable of operating at up to 64 MHz, achieving 16 MIPS performance. A significant advantage of this core is its independent memory architecture, which allows simultaneous access to both program and data memory, boosting throughput.
One of the device's most critical features is its extreme power efficiency, enabled by multiple operational modes. The nanoWatt XLP (eXtreme Low Power) technology allows the device to achieve deep sleep currents as low as 20 nA, making it exceptionally suitable for battery-powered and energy-harvesting applications where longevity is paramount.
The peripheral set is rich and versatile. It includes:
Analog Integration: A 12-bit Analog-to-Digital Converter (ADC) with Computation (ADCC). This advanced module can perform signal analysis (averaging, filtering) autonomously while the CPU sleeps, further conserving power. It also features dual 5-bit DACs and comparators.
Communication Interfaces: A full suite of serial communication modules is present, including EUSART (for UART, LIN), SPI, and I²C. This ensures easy connectivity to sensors, memories, wireless modules, and other system components.
Timing and Control: Multiple PWM (Pulse Width Modulation) outputs, Capture/Compare modules, and a hardware limit timer are integrated for precise motor control, power conversion, and signal generation tasks.
Memory: It boasts 64 KB of self-read/writable Flash program memory and 3.8 KB of RAM, providing ample space for complex applications and data handling.
