This is a high performance DSP-based motor controller
This manual describes the ADMC300, a single‑chip DSP‑based controller for AC induction, permanent‑magnet synchronous and brushless DC motors. It includes a functional block diagram, detailed pin‑function tables, and information on the DSP core, memory, and peripheral subsystems such as PWM generation, encoder interface, and serial ports.
The document also lists electrical specifications, timing requirements, absolute maximum ratings, and ordering information, including package dimensions for the 80‑lead TQFP (ST‑80) version. Safety notes such as ESD handling are provided.

The digital supply voltage (Vpp) should be between 4.5 V and 5.5 V.
The encoder interface can handle pulse rates up to 3.1 MHz.
It is offered in an 80‑lead plastic thin quad flat‑pack (TQFP) designated ST‑80.
The PWM generator provides an edge resolution of 40 ns.
