## Description

## Description

The **IS8705102** is a dedicated hardware protocol controller for the **IEC 60870-5-102 standard**, designed to simplify integration of metering data into embedded systems. It enables microcontrollers to access standardized energy meter information—such as **periodic energy values and end-of-billing-period readings**—without the need to implement the complex IEC 870-5-102 stack in firmware.

By providing the protocol in silicon, the IS8705-102 reduces development time and ensures reliable interoperability with compliant energy meters. Communication with the host microcontroller is done through a simple I2C serial interface, allowing engineers to focus on data handling and system integration rather than low-level protocol details.

This chip is especially suitable for:

* **Photovoltaic installations** (both small-scale and large plants) where operators want independent and automated energy measurement.
 
* **Industrial monitoring systems** requiring standardized access to meter data.
 
* **OEMs** seeking a fast and cost-effective way to embed IEC 870-5-102 support in their products.

With the IS8705-102, developers gain a ready-to-use solution that bridges the gap between energy meters and their monitoring or control systems, ensuring compliance with international standards while saving valuable firmware development resources.
