F2 ULV-CPU
13
The ICS954204 provides an I
2
C (2 wire) interface to program the internal registers. For EMI
reduction the synthesizer provides integrated LCD spread spectrum.
The ICS954204 is housed in 56 pin TSSOP package.
Hardware Monitoring
The PC87366 contains an enhanced Hardware Monitor which will be used for sensing/ con-
trolling the following signals:
the temperature of the processor
Core voltage of the processor
3.3V system voltage
2.5V system voltage for power management
1.5V core voltage
5V system voltage
Battery voltage
12V system voltage
-12V system voltage
Fan tachometer signal of processor fan, system fan and PSU fan
Fan PWM signal for processor fan and system fan
Main Memory
The F2- CPU provides two DIMM(184 Pin) sockets for connecting DDR modules in unbuffered
SDRAM technology from 256MB ( 1 x 256MB) up to 2 Bytes ( 2x 1GB). DDR DIMMs with different
sizes are usable.
One or both DDR DIMM may be assembled. The DDR DIMMs are unbuffered 2.5V memory modules.
