Microchip PIC18F26K22-E/SO 8-Bit Microcontroller Data Sheet and Technical Specifications

The Microchip PIC18F26K22-E/SO is a high-performance, enhanced 8-bit microcontroller from Microchip Technology's renowned PIC18 family. Fabricated with advanced nanoWatt XLP technology, this device is engineered for applications demanding robust performance, low power consumption, and a rich set of peripherals within a compact 28-pin SOIC (Small Outline Integrated Circuit) package.

At its core, the microcontroller features a powerful PIC18 architecture operating at up to 64 MHz, delivering a performance of 16 MIPS (Million Instructions Per Second). This processing power is supported by a substantial 64 KB of self-read/write capable Flash program memory and 3,896 Bytes of RAM, ensuring ample space for complex application code and data handling.

A key strength of the PIC18F26K22 lies in its ultra-low-power management. The nanoWatt XLP technology enables exceptionally low sleep currents, down to 20 nA, making it an ideal choice for battery-powered and energy-harvesting applications where power conservation is critical. The device operates over a wide voltage range (1.8V to 3.6V), further enhancing its versatility in portable designs.

The peripheral set is comprehensive and designed for embedded connectivity. It includes:

Analog-to-Digital Converter (ADC): A 10-bit module with up to 24 channels, facilitating precise sensor interfacing.

Communication Interfaces: Multiple serial communication modules, including EUSART (for RS-232, RS-485), SPI, and I2C™, providing flexible connectivity to other system components.

Timers and CCP: Five timers, along with Capture/Compare/PWM (CCP) and Enhanced CCP (ECCP) modules, offer precise timing and control for motor drives and power conversion.

Comparator and CVREF: Two analog comparators with a fixed voltage reference (CVREF) simplify analog signal conditioning without external components.

The -E suffix in the part number denotes the device's enhanced electrical characteristics, including a wider operating voltage range and improved robustness. The /SO designation specifies the 28-pin SOIC package, suitable for automated assembly processes and space-constrained PCB designs.

ICGOOODFIND: The PIC18F26K22-E/SO stands out as a highly integrated and power-efficient 8-bit MCU solution. Its blend of substantial memory, a rich array of peripherals, and industry-leading low-power technology makes it exceptionally well-suited for a vast range of applications, including industrial control, consumer electronics, medical devices, and Internet of Things (IoT) sensor nodes.
