The late 1980s saw the beginnings of the System-on-Chip (SoC). One of the first true SoCs was the MC68332 from Motorola, Inc. In this chip, Motorola demonstrated simplified SoC integration with standardized physical and electrical interfaces. It was designed specifically for high-end engine controllers and utilized a fully static CMOS 68020 32-bit MPU with specialized table-lookup and interpolation instructions. Engine control functions were performed by a microcoded time-processing unit (TPU). The block diagram and die photo are shown in Figure 1. Figure 1. Block diagram and die photo of the 68332.
