Brief Description

The new modular evaluation kit system of ZMD’s
sensor signal conditioner ICs allows the user a very
simple and intuitive handling of both, evaluation
hardware and software. For the evaluation of different
SSC-ICs only this IC-specific SSC evaluation board
and software has to be interchanged, the other parts
of the evaluation hardware (communication board and
bridge simulator) are almost the same.

The SSC evaluation board allows a simple-to-install­evaluation of ZMD’s SSC-IC matching with this board.
Either this IC is assembled directly on the PCB by
soldering (standard version), or is connected via a
common SSOP-ZIF-socket for simple IC-interchange
(optional).

On board there are two 50-pin-connectors for “plug &
play” – connection to the communication board and (if
necessary) to the sensor replacement board.
Alternatively, by the on-board-screw terminal an
external bridge sensor element can be connected too
for a more realistic evaluation.

On-board-LEDs display the status of 5 VDC-power
supply and (depending on SSC-IC-type) the status of
digital outputs (e.g. ALARM 1 and 2 at ZMD31050).
Several strips allow the access to all signal-I/O-lines of
the SSC-IC for a simple system check.

Every SSC-evaluation board type is hard-coded, this
allows its identification by the µC of the
communication board.

1.1 ZMD31020 USB Evaluation board description

The ZMD31020 Evaluation board is supplied by the regulated 5 VDC-power line controlled by the µC
via a relay of the communication board. Additionally, an on-board-jumper allows the manual cut of the
IC-power supply and a simple measurement of the supply current of the ZMD31020. A red LED
displays the power supply status, its forward current is not included in the measured supply current.

The I
stimulus values and the configuration of the ZMD31020. The EEPROM programming voltage VPP is
supplied by the communication board too. The analog output voltage VOUT of the ZMD31020 is
connected with µC-input “ADC 0”, thus a direct processing of this analog signal by the µC is possible.
This board is hard-coded by three resistors on (D7=L / D6 = H / D5 = L). It is connected to the
communication board via a 50-pin-connector (female). On-board there are two strips for a simple
access on bridge sensor signals, VOUT and bridge power supply voltage. Via a second 50-pin­connector (male) the sensor replacement board can be connected. Alternatively, an external bridge
sensor element is connectable by the on-board screw terminal.
