The MC68332, a highly-integrated 32-bit microcontroller, combines high-performance data manipula tion capabilities with powerful peripheral subsystems. The MCU is built up from standard modules that interface through a common intermodule bus (IMB). Standardization facilitates rapid development of devices tailored for specific applications.
