MCHPPIC18F26K22-I/ML
Overview
The PIC18F26K22-I/ML is a high-performance 8-bit microcontroller featuring Microchip's eXtreme Low Power (XLP) technology and 64KB of Flash memory. Operating at speeds up to 64MHz, it integrates 1024 bytes of EEPROM and 3.8KB of RAM into a compact 28-pin QFN package. This device is optimized for power-sensitive applications requiring robust peripheral sets and high-speed processing on a small footprint.
Why Choose This Part
This MCU offers a compelling balance of 64MHz performance and eXtreme Low Power technology with sleep currents as low as 10uA. It features dual serial ports (2x UART, 2x SPI/I2C) and high-current I/O pins capable of sinking or sourcing 25mA, simplifying direct interfacing with LEDs or small relays. The wide 2.3V to 5.5V operating range ensures compatibility with both legacy 5V systems and modern 3.3V battery-powered designs.
Applications
Key Specifications
Getting Started
Begin development using the MPLAB X IDE and the XC8 compiler provided by Microchip. For hardware debugging and programming, use the MPLAB ICD or PICkit 4 probes via the In-Circuit Serial Programming (ICSP) pins. Evaluation can be performed using the Curiosity Development Board or by designing a custom breakout for the 28-QFN package.
