Intel Intel NetStructure Single Board Computer 4 I/O, 4.1 I/O Controller Hub, Real-Time Clock

MPCBL0010 SBC—Feature Overview

Note: Two 25-degree 240-pin DIMMs theoretically support memory configurations up to 8 GBytes of PC2-3200 registered DDR2-400 SDRAM, but only memory configurations of 2 GBytes and 4 GBytes have been validated.

Table 1.	Supported Memory Configurations
	Total Memory		J10		J12
	2 GBytes	1	GByte DDR2-400 DIMM	1	GByte DDR2-400 DIMM
	4 GBytes	2	GBytes DDR2-400 DIMM	2	GBytes DDR2-400	DIMM

Note: See the Intel NetStructure® MPCBL0010 High-Performance Single Board Computer Compatibility Report, available on the Intel web site, for a complete list of validated memory.

Memory scrubbing is supported and enabled on the MPCBL0010 SBC as described in the Intel E7520 chipset datasheet. There is no additional configuration or driver support required. The memory subsystem is periodically checked and cleansed as the scrubbing process repeats itself over and over. If a correctable memory error is found it is fixed automatically and a "Correctable ECC" event is sent to the SEL. If uncorrectable memory errors are found, an "Uncorrectable ECC" event is sent to the SEL.

2.2.4I/O

2.2.4.1I/O Controller Hub

The 6300ESB ICH includes integrated USB 2.0 and USB Classic support, SATA, an LPC interface, a system management interface, a power management interface, integrated IOxAPIC and 8259 interrupt controllers, and an integrated DMA controller.

See the 6300ESB ICH product-specific documentation as noted in Appendix A, “Reference Documents”for further details.

2.2.4.2Real-Time Clock

The MPCBL0010 SBC real-time clock is integrated into the ICH. It is derived from a

32.768 kHz crystal with the following specifications:

•Frequency tolerance @ 25 ºC: ±20 ppm

•Frequency stability: maximum of -0.04ppm/(ΔºC)2

•Aging ΔF/f (1st year @ 25º C): ±3 ppm

•±20ppm from 0-55º C and aging 1 ppm/year

The real-time clock is powered by a 0.22 F SuperCap capacitor when main power is not applied to the board. This capacitor powers the real-time clock for a minimum of two hours while external power is removed from the MPCBL0010 SBC.

2.2.4.3Timers

The 6300ESB ICH provides three timers. Each is implemented as a single counter with its own comparator and value register. Each timer’s counter increases monotonically. Each individual timer can generate an interrupt when the value in its value register matches the value in the main counter. Some of the timers can be enabled to generate a periodic interrupt.

The registers associated with these timers are mapped to a memory space (much like the I/O APIC). However, this memory space is not implemented as a standard PCI function. The BIOS reports to the operating system the location of the register space.
