Product Summary

The SAB80C537-N is a CMOS Single-Chip Microcontroller. The SAB80C537-N is a high-end member of the Siemens SAB 8051 family of microcontrollers. The SAB80C537-N is designed in Siemens ACMOS technology and based on the SAB 8051 architecture. ACMOS is a technology which combines high-speed and density characteristics with low-power consumption or dissipation.

Parametrics
