Product Summary

The MC68331CFC20 is a highly-integrated 32-bit microcontroller, combines high-performance data manipulation capabilities with powerful peripheral subsystems. The MC68331CFC20 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 MC68331CFC20 incorporates a 32-bit CPU (CPU32), a system integration module (SIM), a general-purpose timer (GPT), and a queued serial module (QSM).
