MC68331CEH20

The MC68331CEH20 is a 32-bit Modular Microcontroller combines high-performance data manipulation capabilities with powerful peripheral subsystems. MCU is built up from standard modules that interface through a common inter-module bus. Standardization facilitates rapid development of devices tailored for specific applications. The MCU incorporates a 32-bit CPU, a system integration module, a general-purpose timer and a queued serial module. 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. Because MCU operation is fully static, register and memory contents are not affected by a loss of clock. High-density complementary metal-oxide semiconductor architecture makes the basic power consumption of the MCU low. The CPU32 instruction set includes a low-power stop command that efficiently implements this capability.
