16-bit embedded controller with integrated DRAM interface
The 16 MHz core clock sets the memory bus timing and the instruction throughput. The integrated DRAM controller supports page-mode access typical of 80C186-family designs.
Integrated DRAM controller — one less chip on the BOM
The on-chip DRAM controller handles the multiplexed address/data bus and refresh timing for standard DRAM arrays. This eliminates a separate DRAM controller or PAL-based glue logic, saving board area and reducing component count. The controller supports a direct interface to DRAM without external address latches for the row/column strobe sequence — a meaningful integration win for a 16-bit embedded system. The part does not include graphics acceleration; video frame buffers would need a separate display controller.
