Introduction
The SAB 80C515/80C535 is a new, powerful member of the Siemens SAB 8051 family of 8-bit
microcontrollers. lt is designed in Siemens ACMOS technology and is functionally compatible with
the SAB 80515/80535 devices designed in MYMOS technology.
The ACMOS and the MYMOS versions ^{1) 2)} are stand-alone, high-performance single-chip
microcontrollers based on the SAB 8051/80C51 architecture. While maintaining all the
SAB 80(C)51 operating characteristics, the SAB 80(C)515/80(C)535³⁾ incorporate several
enhancements which significantly increase design flexibility and overall system performance.
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 power-down mode.
The SAB 80(C)535 is identical to the SAB 80(C)515 except that it lacks the on-chip program
memory. The SAB 80(C)515/80(C)535 is supplied in a 68-pin plastic leaded chip carrier package
(P-LCC-68). In addition to the standard temperature range version (0 ° to + 70 °C) there are also
versions for extended temperature ranges available (see data sheets).
Functional Description
The members of the SAB 80515 family of microcontrollers are:
– SAB 80C515: Microcontroller, designed in Siemens ACMOS technology, with 8-Kbyte
factory mask-programmable ROM
– SAB 80C535: ROM-less version, identical to the SAB 80C515
– SAB 80515: Microcontroller, designed in Siemens MYMOS technology, with 8-Kbyte
factory mask-programmable ROM
– SAB 80535: ROM-less version, identical to the SAB 80515
– SAB 80515K: Special ROM-less version of the SAB 80515 with an additional interface for
program memory accesses. An external ROM that is accessed via the
interface substitutes the SAB 80515’s internal ROM.
1 _{In this User’s Manual the term "ACMOS versions" is used to refer to both the SAB 80C515 and}
SAB 80C535.
2 _{The term "MYMOS versions" stands for SAB 80535 and SAB 80515.}
3 _{The term "SAB 80(C)515" refers to the SAB 80515 and the SAB 80C515, unless otherwise}
noted.
