Intel486™ SX Embedded Processor Overview
The embedded Intel486™ SX processor provides high performance to 32-bit, embedded applications that do not required a floating-point unit. The embedded Intel486 SX processor is binary compatible with the Intel386™ and earlier Intel processors. Compared with the Intel386 processor, it provides faster execution of many commonly used instructions. It also provides the benefits of an integrated 8-Kbyte, write-through cache for code and data. Its data bus can operate in burst mode, which provides up to 106Mbps transfers for cache-line fills and instructions prefetches. Two component packages are available: a 196-Lead Plastic Quad Flat Pack (PQFP), and a 168-Pin Grid Array (PGA), both available for 5-volt designs. Both products operate at CLK frequencies up to 33MHz.
