PRODUCT DESCRIPTION
| The SD186ED demonstration board is a fully functional, stand-alone evaluation platform for the Am186ED microcontroller. The Am186ED microcontroller integrates peripherals such as a DMA controller, memory controller, chip select, dual channel serial controller, programmable I/Os, and timers to increase system functionality while reducing overall cost. The memory controller supports a glueless connection to SRAM, EPROM, FLASH, and DRAM. TheAm186ED 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.
