As a side-effect of the complexity of the design, the CPU did not fit on a single chip. The 68030, released the year earlier, had 273,000 transistors, including the arithmetic logic unit (ALU) and memory management unit (MMU) on a single chip, with the optional floating point unit (FPU) as a separate chip. In contrast, the 88000 packaged the ALU and FPU together on the 750,000 transistor MC88100, and the memory management unit (MMU) and 16 kB static RAM cache in the 750,000 transistor MC88200. In contrast to the 68030 where the FPU was truly optional, a practical 88000 system could not be built without a MC88200. Systems could include more than one MC88200, producing larger caches and allowing multiple paths to main memory for improved performance.
