The MC68332 Technical Summary describes a 32-bit microcontroller built from standard modules that interface through a common intermodule bus. The device combines a 32-bit CPU32, a system integration module (SIM), a time processor unit (TPU), a queued serial module (QSM), and a 2-Kbyte static RAM module with TPU emulation capability (TPURAM).
The document outlines features, block diagram, pin assignments, address map, and signal descriptions. It also covers the system integration module, central processor unit, time processor unit, queued serial module, and standby RAM, and includes ordering information for 132-pin PQFP and 144-pin QFP packages at 16 MHz and 20 MHz across several temperature ranges.
