**82C291 SXWB PC/AT Chipset (386SX) c:91
***Info:
The OPTi SXWB provides a highly integrated solution for fully
compatible, high-performance PC/AT platforms. Since the chipset is so
critical to the performance and cost structure of a PC, this highly
integrated approach provides the foundation for a very cost effective
platform without compromising performance. Together with OPTi’s
82C206 Integrated Peripherals Controller (IPC), this silicon will
support the Intel/AMD 386SX and Cyrix CX486SLC microprocessors in the
most cost effective and power efficient designs available today. This
chipset offers optimum next generation performance for 386SX systems
running up to 33MHz. The OPTi SXWB solution provides the performance
benefits of a 32-bit programming architecture with the cost savings
associated with 16-bit hardware systems. The OPTi SXWB chipset
provides a solution positioned to deliver value, without neglecting
quality, compatibility, or reliability.
The 82C291 integrates a write-back cache controller, a local DRAM
controller, the CPU state machine, the AT bus state machine, and data
buffers all in a single 160-pin Plastic Quad Flat Pack (PQFP). On-chip
hardware provides the hooks for local bus device support.
