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.","metaTitle":"SB80C188-16 16-bit Microprocessor, 16 MHz, i186 Series, 5.0V I/O","metaDescription":"SB80C188-16 16-bit embedded controller from the i186 series. 16 MHz core, 5.0V I/O, integrated DRAM controller.

Both share the same 80C186 core, 5.0V I/O, integrated DRAM controller, and commercial temperature range. The -20 offers a 25% higher clock rate for designs needing tighter loop response, but requires faster memory to avoid wait states."},{"question":"Does SB80C188-16 have a built-in DRAM controller?","answer":"Yes, the SB80C188-16 integrates a DRAM controller on-chip. It handles the multiplexed address/data bus and refresh timing for standard DRAM, eliminating the need for an external DRAM controller or glue logic."},{"question":"What voltage does the SB80C188-16 require?","answer":"The SB80C188-16 operates with a 5.0V I/O supply. This is consistent with the 5V-logic ecosystem of the i186 family."},{"question":"What is the operating temperature range for SB80C188-16?","answer":"The SB80C188-16 is specified for the commercial temperature range of 0°C to 70°C.
