The MC68332ACEH20 is a highly-integrated 32-bit Modular Microcontroller combines high-performance data manipulation 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. The MCU incorporates a 32-bit CPU (CPU32), a system integration module (SIM), a time processor unit (TPU), a queued serial module (QSM) and a 2kB static RAM module with TPU emulation capability (TPURAM). The MCU can either synthesize an internal clock signal from an external reference or use an external clock input directly. Operation with a 32.768kHz reference frequency is standard. The maximum system clock speed is 20.97MHz. System hardware and software allow changes in clock rate during operation.
