MC68331|32 Bit Microcontroller (MCU)

For best experience this site requires Javascript to be enabled. To enable on your browser, follow our accessibility instructions.

The MC68331 is a highly-integrated 32 bit microcontroller that combines high-performance data manipulation capabilities with powerful peripheral subsystems.This MCU is built up from standard modules that interface through a common intermodule bus (IMB).

The MCU incorporates a 32 bit CPU (CPU32), a system integration module (SIM), a general purpose timer (GPT) and a queued serial module (QSM).
