ZSSC3241
Sensor Signal Conditioner IC for Resistive Sensors
Description
ZSSC3241 SSC Evaluation Kit is designed for
sensor module evaluation, laboratory setup, and
module calibration development for the ZSSC3241
Sensor Signal Conditioner (SSC).
The main purpose of the ZSSC3241 Evaluation Kit
is to enable the communication between the user
and the ZSSC3241 device with the GUI (Graphical
User Interface). The ZSSC3241-GUI establishes the
communication via a USB port (configured as a
virtual COM port) to the SSC Communication Board
(CB). The microcontroller on the SSC CB interprets
these commands, converts them to the configured
interface (I2C, SPI, or OWI), and provides it to the
ZSSC3241 located on the ZSSC3241 SSC
Evaluation Board.
Almost all possible applications can be tested with
the Evaluation Kit and the GUI, so that the customer
can easily get the first experience and also evaluate
in detail the ZSSC3241 functionalities.

Sensor and Temperature Readings Sensor (external and temperature) readings from the ZSSC3241 are indicated in the numerical displays (see Figure 23). The displays show the recent measurement value in the decimal notation. As the measurement values in Measurement tab and measurement log, the output of the numerical displays is defined by the settings in the Display Control (see section 2.4).

New CRC calculation can be triggered by clicking the ‘Write CRC’ button (see Figure 42). On start-up, the GUI automatically attempts to read the memory content of the connected ZSSC3241. If it fails, the NVM tab displays the value 0 for all registers.

ADC Diagnostic When the ‘Apply ADC-Diagnostic’ button is clicked to activate the ADC Diagnostic, the standard sensor processing path is disconnected. Instead, an analog differential voltage ranging from -15mV to +15mV is directly input to the ADC, which performs a conversion using the SM_config registers setup. The input is realized via a decimal number from 0 to 31, which are directly mapped to the mV stages from -15mV to 15mV.
