congatec Battery Management Interface
To facilitate the development of battery powered mobile systems based on embedded modules, congatec GmbH defined an interface for
the exchange of data between a CPU module (using an ACPI operating system) and a Smart Battery system. A system developed according
to the congatec Battery Management Interface Specification can provide the battery management functions supported by an ACPI capable
operating system (for example, charge state of the battery, information about the battery, alarms/events for certain battery states and so on)
without the need for additional modifications to the system BIOS.
In addtion to the ACPI-Compliant Control Method Battery mentioned above, the latest versions of the conga-TC570 BIOS and board controller
firmware also support LTC1760 battery manager from Linear Technology and a battery only solution (no charger). All three battery solutions are
supported on the I2C bus and the SMBus. This gives the system designer more flexibility when choosing the appropriate battery sub-system.
For more information about the supported Battery Management Interface, contact your local sales representative.

API Support (CGOS)
In order to benefit from the above mentioned non-industry standard feature set, congatec provides an API that allows application software
developers to easily integrate all these features into their code. The CGOS API (congatec Operating System Application Programming
Interface) is the congatec proprietary API that is available for all commonly used Operating Systems such as Win32, Win64, Win CE, Linux.
The architecture of the CGOS API driver provides the ability to write application software that runs unmodified on all congatec CPU modules.
All the hardware related code is contained within the congatec embedded BIOS on the module. See section 1.1 of the CGOS API software
developers guide, available on the congatec website.

Security Features
The conga-TC570 offers a discrete SPI TPM 2.0 (Infineon SLB9670VQ2.0) by default.
6.6
Suspend to Ram
The Suspend to RAM feature is available on the conga-TC570.
