SAB82C257-1-N - (SAB82C25x-x-N) Advanced DMA Controller

Download the SAB82C257-1-N datasheet PDF. This datasheet also covers the SAB82C258A-20-N variant, as both devices belong to the same (sab82c25x-x-n) advanced dma controller family and are provided as variant models within a single manufacturer datasheet.

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.

Features

  • 16-bit DMA controller for 16-bit family processors.
  • SAB 80286.
  • SAB 80186 188.
  • SAB 8086/88.
  • 4 independent high-speed DMA channels.
  • 16 Mbyte addressing range.
  • 16 Mbyte maximum block length.
  • Memory based communication with CPU.
  • “On-the fly” compare, translate and verify operations.
  • Transfer rates up to 10 Mbyte/s.
  • 32-bit-fly-by transfers with up to 20 Mbyte/s (10-MHz system).
  • Single cycle an.

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.
