Product Summary
The P80C32UBA is a single-chip control-oriented microcontroller which is fabricated on Intels reliable CHMOS III-E technology. Being a member of the MCS 51 family of controllers, the P80C32UBA uses the same powerful instruction set, has the same architecture, and is pin-for-pin compatible with the existing MCS 51 family of products. The added features make it an even more powerful microcontroller for applications that require clock output, and up/down counting capabilities such as motor control. The P80C32UBA also has a more versatile serial channel that facilitates multi-processor communications.
