AM4024(E)
2.1.1 Integrated Processor Graphics Controller
The 4
th
gen. Intel® Core™ i7/i5 processor includes a highly integrated processor graphics controller
with up to 40 execution units delivering high-performance 3D, 2D graphics capabilities. The
AM4024(E) uses one display interface of the integrated processor graphics controller and supports res-
olutions up to 3840 x 1160 pixels @ 60 Hz through DisplayPort and up to 1920 x 1200 pixels @ 60 Hz
using DVI.
2.2 Memor y
The AM4024(E) supports a soldered, dual-channel (144-bit), Double Data Rate (DDR3) memory with Er-
ror Checking and Correcting (ECC) running at 1600 MHz (memory error detection and reporting of 1-
bit and 2-bit errors and correction of 1-bit failures). The available memory configuration can be either
8 GB or 16 GB.
However, when the internal graphics controller is enabled, the amount of memory available to appli-
cations is less than the total physical memory in the system. For example, the chipset’s Dynamic Video
Memory Technology dynamically allocates the proper amount of system memory required by the oper-
ating system and the application.
2.3 Watchdog Timer
The AM4024(E) provides a Watchdog timer that is programmable for a timeout period ranging from 125 ms
to 4096 s in 16 steps.
The Watchdog timer provides the following modes of operation:
»
Timer-only mode
»
Reset mode
»
Interrupt mode
»
Dual-stage mode
In dual-stage mode, a combination of both interrupt and reset is generated if the Watchdog is not ser-
viced.
2.4 Batter y
The AM4024(E) does not have any provisions for an onboard battery for backup of the RTC. There is,
however, an optional mezzanine module available which does provide battery-powered backup for the
RTC. The RTC Backup Battery module uses the J7 connector for interfacing with the AM4024(E). If this
module is required, the J7 interface is not available for the SATA Flash module. Refer to Chapter 7
for
further information on this module.
