Product Brief

AMD SD186ES Stand-Alone Evaluation Platform

The SD186ES demonstration board provides a complete stand-alone microcontroller-based evaluation platform in a low-cost, very small form-factor product for those developers working with the Am186™ES microcontroller.

The Am186ES microcontroller is designed to meet the most common requirements of embedded products developed for the office automation, mass storage, communications, industrial, and general embedded markets. The SD186ES board demonstrates the basic processor functionality and features of the Am186ES microcontroller and the simplicity of its system design.

Product Description

The SD186ES demonstration board is a fully functional stand-alone evaluation platform for the Am186ES microcontroller. The Am186ES microcontroller integrates peripherals such as a DMA controller, memory controller, chip select, dual channel serial controller, programmable I/Os, and timers to increase a system's functionality while reducing overall cost. The memory controller supports a glueless connection to SRAM, EPROM, FLASH, and Pseudo-Static RAM. The Am186ES microcontroller also features an innovative bus design that frees the processor to run at nearly twice the speed of standard 80C186 processors--without an increase in memory speed requirements.
