MCHPPIC18F25K22-I/SO
Overview
The PIC18F25K22-I/SO is a high-performance 8-bit microcontroller featuring Microchip's eXtreme Low Power (XLP) technology and a 64MHz maximum clock speed. This 28-pin SOIC device includes 32KB of Flash memory, 256 bytes of EEPROM, and a wide operating voltage range up to 5.5V. It is designed for applications requiring high computational throughput alongside strict power consumption targets.
Why Choose This Part
This MCU offers a high I/O-to-pin ratio with 25 GPIOs in a compact 28-pin package and supports 5V tolerant inputs for interfacing with legacy hardware. Its flexible power management, including Idle and Sleep modes, allows engineers to optimize performance against current draw down to 13uA in specific idle states.
Applications
Key Specifications
Getting Started
Development is best supported by the MPLAB X IDE and the XC8 compiler. Hardware debugging can be performed using the MPLAB PICkit 4 or ICD 4 via the In-Circuit Serial Programming (ICSP) interface. For rapid prototyping, the PIC18F25K22 can be evaluated using the Curiosity Development Board or by mounting the SOIC package to a standard 28-pin adapter.
