SAB80C537-N

Product Summary

The SAB80C537-N is an 8-Bit CMOS Single-Chip Microcontroller. 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-N is identical with the SAB 80C517 except that it lacks the on-chip program memory.

Parametrics

SAB80C537-N absolute maximum ratings: (1)Ambient temperature under bias: 0 to 70℃; (2)Storage temperature, TST: – 65 to 150℃; (3)Voltage on VCC pins with respect to ground (VSS): – 0.5 V to 6.5 V; (4)Voltage on any pin with respect to ground (VSS): – 0.5 to VCC+0.5 V; (5)Input current on any pin during overload condition: – 10mA to +10mA; (6)Absolute sum of all input currents during overload condition: |100mA|; (7)Power dissipation: 2 W.
