What is the performance difference between PCMCIA and CardBus PC Cards?
PCMCIA (16-bit) PC Cards can typically operate at speeds less than 10 MB/sec. CardBus PC Cards can run as fast as the PCI bus (132 MB/sec), but in realistic systems today the performance is limited by the burst performance of other devices on the PCI bus. TI’s PCI12xx series controllers are capable of bursting data up to the 132 MB/sec performance of the PCI Bus. TI’s competitors have, up to now, only released controllers which support burst performance between 5-60 MB/sec based on initial evaluations. • Does TI perform Compatibility Testing with TI’s PC Card Controllers? TI performs extensive compatibility testing with over 200 different PC Cards on various operating systems and using various Card & Socket Services drivers. In addition, TI is developing a compatibility testing program where TI’s customers can submit prototype systems for compatibility testing in TI’s lab. • What CardBus PC Cards has TI tested? Intel Video Capture Card, SMC 100 Mb Ethernet, TDK 100 Mb Ethernet,Xircom 1
