Embedded Controller (EC) Firmware

Rating: 3.33 (5 ratings)

The embedded controller (EC) is an essential component in modern mobile, ultra-mobile and embedded computer systems. An efficient EC sub-system enables energy-conscious designs to obtain dramatic power savings.

The latest EC silicon feature higher processing power and complex features, requiring a more robust firmware solution. With over 25 years of experience in BIOS and keyboard controller programming, AMI is the best candidate to provide an advanced EC firmware solution.

Since the first AMIKEY firmware was released for 8042-compatible controllers, AMI has consistently adapted to the shift from the basic keyboard controller to full-featured EC products.

Advanced Functionality:
* Keyboard Controller Functionality: AT and PS/2 8042 Compatibility with support for matrix keyboard scan controllers, device hot-swap, hot-plug and OEM hot-key implementations.
* ACPI Embedded Controller: Full compatibility with ACPI EC requirements
* Smart Battery Management: SMBus interface for smart or control method batteries
* OEM Customization: Utilize EC advanced functionality to create unique platform functionality. Including general purpose I/O (GPIO), analog-to-digital convertor (ADC), pulse-width modulator (PWM) and watch dog timer (WDT) functionality.

Flexible Development Options:
* Full source code available for development
* Firmware development in C or assembly language (depends on part selection)
* Supports ShareBIOS and Internal Flash implementations (depends on part selection)
* AMI offers EC firmware ported to many popular chipset reference board (CRB) designs.

Though AMI claim to provide the EC source code for development, we are finding difficulty to get the EC source code from our local AMI office.

What is the procedure to get the EC source code (Crown beach CRB/H8S2117R)?

你们好 我现在使用的是ATOM Z530的芯片组开发工业控制板（在代理商那里购买了一块开发板 EC 是 二进制的文件），但是在开发过程想改变其中 EC 的设计（H8S2117R 芯片），但是没有源代码。不知道我怎样才能获得此EC的源代码。

How are you I am now using ATOM Z530 chipset development of industrial control panel (in the agent purchased a development board where the EC is a binary file), but in the development process in which EC want to change the design (H8S2117R chip), but did not the source code. I do not know how to get the source code for this EC.
