www.DataSheet4U.com Advanced DMA Controller for 16-Bit Microcomputer Sytems (ADMA) SAB 82C257 SAB 82C258A General Description The SAB 82258A is an advanced general-purpose fourchannel DMA controller tailored for efficient high speed data transfer between peripheral devices and memories. It is either coupled tightly with a companion CPU (local mode) or working in stand alone applications using the remote mode. The SAB 82258A is unique among DMA controllers providing complete direct interfacing to the SAB 80286 as well as to SAB 80186/188/86/88 bus. Its four superfast DMA channels transfer rate up to 10 Mbytes per second are possible. If the maximum transfer rate reaches as much as 20 Mbyte/second.
