5.18 Real Time Clock
An external 32.768 kHz crystal sources the internal real time clock inside ICH10R with a
frequency tolerance of 20 PPM. The RTC is fully DS1287, MC14618, PC87911 and Y2K
compliant and provides 256 bytes of backed up CMOS RAM (of which 14 bytes containing the
RTC time and date information and RTC configuration). During power-down, the RTC
consumes 0.9uA/hr. The optional power-down backup method uses a Super CAP with a 1 Farad
capacity. This provides 300 hours of RTC/SRAM backup. The default battery is an external +3V
lithium battery with a capacity of 200mAh, which provides three years of backup.
5.19 VGA Module
The VGA-7360 module is based on XGI Volari Z11M graphics controller and delivers the
following features on a standard DSUB15 pin analog VGA graphics connector at the faceplate:
 High Performance 2D Accelerator
 8 MB Integrated MCM Memory
 Analog CRT output with maximum 230 MHz pixel clock and graphics mode up to
1920x1200
Certain variants of ATCA-7365 supports the VGA-7360 module. They are:
 ATCA-7365-D-0GB-V
 ATCA-7365-D-24GB-V
 ATCA-7365-D-48GB-V
