Microchip PIC18F26K20-I/ML 8-Bit Microcontroller Overview

The Microchip PIC18F26K20-I/ML is a high-performance 8-bit microcontroller built on an enhanced PIC18 architecture. This device combines robust processing capabilities with versatile peripherals, making it a compelling choice for a wide range of embedded control applications in the industrial, automotive, and consumer markets. Housed in a compact 28-pin QFN (ML) package, it is designed for space-constrained designs requiring a powerful computational core.

At its heart, the microcontroller features a 16 MIPS performance at 64 MHz operation, enabled by an internal PLL. This ensures efficient execution of complex control algorithms. A significant architectural advantage is its nanoWatt XLP technology, which provides extremely low power consumption. This is critical for battery-powered and energy-harvesting applications, allowing for extended operation without frequent battery replacement.

The memory subsystem is substantial for an 8-bit core. It includes 64 KB of self-read/write capable Flash program memory and 3896 bytes of RAM. This generous memory space supports larger application codes and more complex data handling than many competitors in its class. Furthermore, it boasts 1024 bytes of data EEPROM, offering reliable non-volatile storage for critical parameters.

Its peripheral set is rich and diverse. Key communication interfaces include EUSART, SPI, and I2C modules, facilitating easy connection to sensors, displays, and other system components. For precision control, it is equipped with two analog comparators and a 10-bit Analog-to-Digital Converter (ADC) with up to 13 channels. This allows for accurate monitoring of analog signals from the environment. The controller also features multiple timers and two CCP (Capture/Compare/PWM) modules, which are essential for generating precise waveforms for motor control and other timing-critical functions.

Operating over an extensive voltage range (2.0V to 5.5V) and across a wide temperature spectrum (-40°C to +85°C), the PIC18F26K20-I/ML is engineered for reliability in harsh and demanding environments.

ICGOODFIND: The PIC18F26K20-I/ML stands out as a highly integrated, power-efficient 8-bit solution. Its blend of high computational speed, extensive memory, nanoWatt XLP technology, and a comprehensive peripheral set makes it an exceptionally versatile microcontroller for developers aiming to balance performance with low power consumption in compact designs.
