SELECTION OF MICROCONTROLLER

Although the microcontroller used in this project is

MC68HC05B16, a smaller ROM version microcontroller can

also be used. The table below shows the requirement of

microcontroller for this blood pressure meter design in this

project.

Table 1. Selection of microcontroller

On–chip ROM space 2 kilobytes

On–chip RAM space 150 bytes

2–channel A/D converter (min.)

16–bit free running counter timer

LCD driver

On–chip EEPROM space 32 bytes

Power saving Stop and Wait modes

CONCLUSION

This circuit design concept may be used to evaluate

Motorola pressure sensors used in the digital blood pressure

meter. This basic circuit may be easily modified to provide

suitable output signal level. The software may also be easily

modified to provide better analysis of the SBP and DBP of a

person.
