The SAB 80C515/80C535 is a powerful member of the Siemens SAB 8051 family
of 8-bit microcontrollers. It is designed in Siemens ACMOS technology and is functionally
compatible with the SAB 80515/80535 devices designed in MYMOS technology.
The SAB 80C515/80C535 is a stand-alone, high-performance single-chip microcontroller
based on the SAB 8051/80C51 architecture. While maintaining all the SAB 80C51 operating
characteristics, the SAB 80C515/80C535 incorporates several enhancements which
significantly increase design flexibility and overall system performance.
In addition, the low-power properties of Siemens ACMOS technology allow applications where
power consumption and dissipation are critical. Furthermore, the SAB 80C515/80C535 has
two software-selectable modes of reduced activity for further power reduction: idle and powerdown mode.
The SAB 80C535 is identical with the SAB 80C515 except that it lacks the on-chip program
memory. The SAB 80C515/80C535 is supplied in a 68-pin plastic leaded chip carrier package
(P-LCC-68) or in a plastic metric quad flat package (P-MQFP-80).
There are versions for 12, 16 and 20 MHz operation and for 16 MHz operation and for extended
temperature ranges – 40 to 85 ˚C. Versions for extended temperature range – 40 to + 110 ˚C
are available on request.
