Kontron caters for the lack of Super I/O with legacy support by using an additional module to which the user can optionally add a CompactFlash, an HDD microdrive up to 1 GByte or a 2.5 inch HDD. The CP304 goes even further than the other members of the 300 family towards fulfilling the customer demands for the most flexible selection possible for computing power and memory capacity. Consequently, the CP304 is fitted with a processor socket which supports the implementation of all Intel? Pentium? III processors in the FC-PGA and FC-PGA2 housings - from Celeron with 566 MHz and 128 KB L2 cache, through the Intel? Pentium? III with 256 KB to the latest Intel? Pentium? III-S processor with 512 KB. The synchronous DRAM memory (max. 512 MB) operates at 133 MHz and is accommodated in a SODIMM socket. The clock rate of 1.26 GHz will become established for availability over the long term, whereby the clock rate though will probably be developed up to 1.53 GHz.
