P89LPC938
8-bit microcontroller with 10-bit A/D converter
7.29 User conguration bytes
Some user-congurable features of the P89LPC938 must be dened at power-up and
therefore cannot be set by the program after start of execution. These features are
congured through the use of the Flash byte UCFG1. Please see the
P89LPC938 User’s
Manual for additional details.
7.30 User sector security bytes
There are eight User Sector Security Bytes on the P89LPC938. Each byte corresponds to
one sector. Please see the
P89LPC938 User’s Manual for additional details.

A/D converter
8.1 General description
The P89LPC938 has a 10-bit, 8-channel multiplexed successive approximation
analog-to-digital converter module. A block diagram of the A/D converter is shown in
Figure 21. The A/D consists of an 8-input multiplexer which feeds a sample-and-hold
circuit providing an input signal to one of two comparator inputs. The control logic in
combination with the SAR drives a digital-to-analog converter which provides the other
input to the comparator. The output of the comparator is fed to the SAR.
8.2 Features
s 10-bit, 8-channel multiplexed input, successive approximation A/D converter.
s Eight result register pairs.

s 10-bit conversion time of 4
s at an A/D clock of 9 MHz
s Interrupt or polled operation
s High and Low Boundary limits interrupt; selectable in or out-of-range
s Clock divider
s Power-down mode
