Figure 53. Typical System Configuration
comes with the single-pin emulator available from Accutron Limited
(www.accutron.com), use a 2-pin 0.1-inch pitch “Friction Lock”
header from Molex (www.molex.com) such as their part number
22-27-2021. Be sure to observe the polarity of this header. As
represented in Figure 53, when the Friction Lock tab is at the
right, the ground pin should be the lower of the two pins (when
viewed from the top).
Enhanced-Hooks Emulation Mode
ADuC824 also supports enhanced-hooks emulation mode. An
enhanced-hooks-based emulator is available from Metalink
Corporation (www.metaice.com). No special hardware support
for these emulators needs to be designed onto the board since
these are “pod-style” emulators where users must replace the chip
on their board with a header device that the emulator pod plugs
into. The only hardware concern is then one of determining if
adequate space is available for the emulator pod to fit into the
system enclosure.
Typical System Configuration
A typical ADuC824 configuration is shown in Figure 53. It sum-
marizes some of the hardware considerations discussed in the
previous paragraphs.
Figure 53 also includes connections for a typical analog mea-
surement application of the ADuC824, namely an interface to
an RTD (Resistive Temperature Device). The arrangement
shown is commonly referred to as a 4-wire RTD configuration.
Here, the on-chip excitation current sources are enabled to excite
the sensor. An external differential reference voltage is generated
by the current sourced through resistor R1. This current also
flows directly through the RTD, which generates a differential
voltage directly proportional to temperature. This differential
voltage is routed directly to the positive and negative inputs of
the primary ADC (AIN1, AIN2 respectively). A second external
resistor, R2, is used to ensure that absolute analog input voltage
on the negative input to the primary ADC stays within that
specified for the ADuC824, i.e., AGND + 100 mV.
It should also be noted that variations in the excitation current
do not affect the measurement system as the input voltage from
the RTD and reference voltage across R1 vary ratiometrically with
the excitation current. Resistor R1 must, however, have a low
temperature coefficient to avoid errors in the reference voltage
over temperature.
