Fundamental Structure

2 Fundamental Structure

The SAB 80C515A/83C515A-5 is a high-end member of the Siemens SAB 8051 microcontroller

family. 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.

While maintaining all the SAB 80C515 features and operating characteristics the SAB 80C515A/

83C515A-5 contains more on-chip RAM/ROM. Furthermore a new 10-bit A/D-Converter is

implemented as well as extended security mechanisms. The SAB 80C515A is identical with the

SAB 83C515A-5 except that it lacks the on-chip program memory. The SAB 80C515A/

83C515A-5 is supplied in a 68-pin plastic leaded chip carrier package (P-LCC-68).

The essential enhancements to the SAB 80C515 are (see also figure 2-1):

– Additional 1KByte RAM on chip

– 8-Channel 10-bit A/D Converter

– New baud rate generator for the Serial Channel

– Oscillator Watchdog Unit

– Improved functionality of the Watchdog Timer

– Hardware controlled Power Down Mode

– High speed operation of the device (up to 18 MHz crystal frequency)
