SAB80C537-16-NT40/85

The SAB80C537-16-NT40/85 is a kind of high-end member of the Siemens SAB 8051 family of microcontrollers, which 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.

Features of the SAB80C537-16-NT40/85 are:(1) fast 32-bit division, 16-bit 2 mutipication,32-bit normaize and shift by periphera; (2) 8 K x 8 ROM (SAB 80C517 ony) ; (3) 256 x 8 on-chip RAM ; (4) four 16-bit timer/counters ; (5) powerful 16-bit compare/capture unit  nine ports: 56 I/O lines, 12 input lines; (6):  extended power saving modes; (7): eight data pointers for externa memory.

The absolute maximum ratings of the SAB80C537-16-NT40/85 can be summarized as:(1): storage temperature (TST) is  65 to 150; (2): voltage on VCC pins with respect to ground (VSS) is 0.5 V to 6.5 V; (3): voltage on any pin with respect to ground (VSS) is 0.5 V to VCC+0.5 V; (4): input current on any pin during overload condition is 10mA to +10mA; (5): absolute sum of all input currents during overload condition is |100mA|; (6): power dissipation is 2 W.
