Description:
82C283 386SX System Controller
The 82C283 is a highly integrated, AT system logic VLSI chip for high-end 386SX/AT systems. It integrates a local memory controller (local memory is on-board memory), AT bus controller, and data bus controller into one chip. It is designed for systems running at 16MHz, 20MHz, 25MHz, and 33MHz*. A high performance, compact 386SX/AT system is readily implemented with the 82C283 and a standard peripheral controller like OPTi's 82C206 or the 82C100 (with Dallas Semi-conductor (DS1287).
