• Compact size: 7mm x 7mm package, with 12 I/O lines and 2 oscillator pins.
• Up to 256KB Flash Memory.
• 256 bytes Data Memory (EEPROM).
• 8K of RAM.
• Serial Port (SPI and I2C).
• 10-bit Analog-to-Digital (A/D) Converter.
• Six High-Speed I/O Pins.
• Low Power Modes.

Application Field

The PIC18F25K40-I/SS is ideal for low power embedded applications that require a high degree of performance. It is well suited for a wide range of applications, including:

• Motor Control.
• Industrial Automation.
• Telecommunication.
• Energy Monitoring.

Working Principle

The PIC18F25K40-I/SS works by executing instructions which are stored in its Flash Memory. The Flash Memory is divided into 8K blocks, which are made up of 8192 Flash locations. Each location can store 14 bits of data. The 14-bit instruction is divided into three parts: the first 12 bits are the instruction code, the second 2 bits are the instruction type, and the last 2 bits are the instruction options. Each instruction takes a single Flash location, so each instruction is a single 8192 instruction address.

The PIC18F25K40-I/SS also has a Data Memory (EEPROM) which can store up to 256 bytes of data. This data is accessed via software, and the address and data of each byte can be controlled by the user. The Data Memory can also be used to store system configuration and program constants.

The PIC18F25K40-I/SS also includes several analog-to-digital (A/D) converters, serial interfaces, I/O ports, and other peripherals. The A/D converters allow the microcontroller to measure analog signals, while the serial interfaces allow the microcontroller to communicate with other microcontrollers or devices. Finally, the I/O ports allow the microcontroller to control and monitor external devices.

Conclusion

The PIC18F25K40-I/SS is a powerful 8-bit microcontroller that is well suited for low power embedded applications. It features 256KB Flash Memory, an A/D Converter, and several serial interfaces. Its low power consumption and high performance make it ideal for home automation, telecommunications, and industrial control applications.
