SAB80515 Datasheet, PDF (15/270 Pages) Siemens Semiconductor Group – 8-Bit Single-Chip Microcontroller Family

Fundamental Structure
2.1.5 A/D Converter Timings
See the corresponding data sheets for the specification of t_L (load time), t_S (sample time), t_C
(conversion time).
2.1.6 The Oscillator and Clock Circuits
There is no difference between the MYMOS and ACMOS versions if they are driven from a crystal
or a ceramic resonator.
Please note that there is a difference between driving MYMOS and ACMOS components from
external source. How to drive each device is described in chapter 7.8.2 and in each data sheet.
2.1.7 The V_BB Pin
The SAB 80515/80535 has an extra V_BB pin connected to the device’s substrate. lt must be
connected to V_SS through a capacitor for proper operation of the A/D converter.
The SAB 80C515/80C535 has no V_BB pin. In ACMOS technology the substrate is directly connected
to V_CC ; therefore, the corresponding pin is used as an additional V_CC pin.
