MC68332ACEH25

MC68332ACEH25 is a highly integrated 32-bit microcontroller that combines high-performance data manipulation capabilities with powerful peripheral subsystems. The MCU is built up of standard modules that interface through a common intermodule bus. Standardization facilitates the rapid development of devices tailored for specific applications. The MCU incorporates a 32-bit CPU, a system integration module, a time processor unit, a queued serial module, and a 2Kbyte 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. Because MCU operation is fully static, register and memory contents are not affected by clock rate changes.
