The integrated processor combines a CPU32 M68000-family core, a 32-bit DMA controller, and on-chip peripheral subsystems. It supports a 16-bit external memory system, background debug operation, IEEE 1149.1 boundary-scan test access, timers, and serial communications. The 16E speed grade corresponds to 16.78 MHz operation, with standard MC68340 electrical specifications referencing a 5 V supply.
