The Core
Peripherals
Device Structure
Each part of a device can be placed into one of three groups:
1.
2.
3.
The core pertains to the basic features that are required to make the device operate. These
include:
1.
2.
3.
4.
5.
6.
7.
Peripherals are the features that add a differentiation from a microprocessor. These ease in inter-
facing to the external world (such as general purpose I/O, LCD drivers, A/D inputs, and PWM
outputs), and internal tasks such as keeping different time bases (such as timers). The peripher-
als that are discussed are:

10. Voltage References
11. Comparators
12. 8-bit Analog to Digital (A/D)
13. Basic 8-bit Analog to Digital (A/D)
14. 10-bit Analog to Digital (A/D)
