SAB80C515A-5 Datasheet, PDF (5/108 Pages) Siemens Semiconductor Group – 8-Bit CMOS Single-Chip Microcontroller Family

Introduction
The SAB 80C515A is available in two different versions:
– "ROMless" Version SAB 80C515A. Although this part is called "ROMless" there is an internal
ROM of 2 KByte (for Test and Loader Software)
– ROM Version SAB 83C515A-5. This part has 32 KByte on-chip ROM.
With exception of the ROM sizes both parts are identical. Therefore the term SAB 80C515A refers
to both versions within this specification unless otherwise noted.
This manual describes only the new features of the SAB 80C515A in addition to the features of the
SAB 80C515/80C535. For reference to the SAB 80C515, the user's manual should be used.
Listed below is a summary of the main features of the SAB 80C515A:
q SAB 80C515A/83C515A-5, up to
18 MHz operation frequency
