2.7.3
CompactFlash*
The IQ80315 CRB supports a 3.3 V, 16-bit CompactFlash* type II socket on the peripheral bus.
The CompactFlash interface is compliant with the CF+ v1.4 CompactFlash specification. The
CompactFlash interface of the IQ80315 CRB supports memory and I/O accesses. CompactFlash
ATA cards are not supported.
The CompactFlash card interface to the IQ80315 CRB board is through an AVX 50-pin socket
mounted in the rear panel gasket area.
The CompactFlash socket is connected to PCE1# and responds to the address ranges identified in
Section
3.2. The CompactFlash interface connects to the buffered peripheral bus interface
generated by the CPLD to protect the 80314 from ESD. The CPLD also generates the I/O read and
I/O write signals for accesses to the upper 512 KB of the CompactFlash address range.
When the system is powered-up and not in reset, inserting a CompactFlash card into the socket
generates an interrupt. See
2.7.4
LCD Support
The IQ80315 CRB has a 14-pin LCD header and 2-pin backlight header to support a character-
based LCD module. The IQ80315 CRB supports the following LCD modules:
•
Lumex* Opto* LCM-S02404DSF
•
Varitronix* MDLS-20265
The CPLD generates the LCD chip enable (LCD_CE#) and register-select (LCD_RS) signals. See
Section 3.2
A 10 KΩ trimpot mounted in the gasket area is used to adjust the LCD contrast voltage (Vo)
between 0 V and 5 V.
Connecting the +5 V power plane through a diode to the backlight connector generates the 4.2 V
backlight voltage.
2.7.5
LEDs
The IQ80315 CRB contains power, hard-drive, and seven-segment LEDs to communicate current
system status.
There is a green LED on the board for each major power plane: +12 V, +5 V, and +3 V. When
power is applied to these power planes, the associated LED is lit.
The board has nine hard-drive activity LEDs. There are eight blue LEDs (one for each hard drive),
and one aggregated green LED. One blue LED is connected to each Intel
is illuminated whenever the associated hard drive is being accessed. The green LED is illuminated
whenever any of the hard drives is being accessed.
The board has a pair of Agilent* HDSP-G211 seven-segment LEDs for displaying POST codes or
other software generated debug codes. Both seven-segment LEDs are individually addressed. See
