AM186ES-40KC – AMD

The AM186ES-40KC is an embedded x86 processor manufactured by AMD. It operates at a clock frequency of 40 MHz, providing a balance of performance and power consumption suitable for embedded systems applications. This specific part number, AM186ES-40KC, is identified as non-RoHS compliant, indicating the presence of lead or other restricted substances exceeding allowable limits as defined by the Restriction of Hazardous Substances Directive. The AM186ES core is a 16-bit processor with integrated peripheral support, including timers, DMA controllers, and interrupt controllers, reducing the need for external components. Its instruction set is largely compatible with the Intel 80186 architecture, facilitating code migration and development. The “ES” designation suggests an engineering sample or early silicon revision, which may have different characteristics or limitations compared to production versions.
