SAB80C537

Product Summary

The SAB80C537 is a high-end member of the Siemens SAB 8051 family of microcontrollers. It 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. The SAB80C537 is identical with the SAB 80C517 except that it lacks the on-chip program memory. The SAB80C537 is supplied in a 84 pin plastic leaded chip carrier package (P-LCC-84) and in a 100-pin plastic quad metric flat package (P-MQFP-100-2).
