SAB80C537-16N

The SAB80C537-16N is one member of the SAB80C537 series.The SAB 80C537 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.

Features of the SAB80C537 are:(1) eight data pointers for external memory addressing;(2) fourteen interrupt vectors, four priority levels selectable;(3)powerful 16-bit compare/capture unit(CCU) with up to 21 high-speed or PWM output channels and 5 capture inputs;(4)8-bit A/D converter with 12 multiplexed inputs and programmable ref. voltages;(5)two full duplex serial interfaces.Use of the software controlled power saving modes is blocked, when this pin is held on high level. A high level during reset performs an automatic start of the watchdog timer immediately after reset.When left unconnected this pin is pulled high by a weak internal pull-up resistor.All registers, except the program counter and the four general purpose register banks, reside in the special function register area. The 81 special function registers include arithmetic registers, pointers, and registers that provide an interface between the CPU and the on-chip peripherals. There are also 128 directly addressable bits within the SFR area.

Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage of SAB80C537-16N. SAB80C537-16N is a stress rating only and functional operation of SAB80C537-16N at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for  longer periods may affect device reliability. During overload conditions (VIN > VCC or VIN < VSS)theVoltageonVCC pins with respect to ground (VSS) must not exeed the values definded by the absolute maximum ratings.Exceeding the limit values at one or more input channels will cause additional current which is sinked sourced at these channels. SAB80C537-16N may also affect the accuracy of other channels which are operated within the specification.
