Description
The ZSSC324x SSC Evaluation Kit is designed for sensor module
evaluation, laboratory setup, and module calibration development
for the ZSSC324x Sensor Signal Conditioner (SSC).
The main purpose of the ZSSC324x Evaluation Kit is to enable the
communication between the user and the ZSSC324x device with
the GUI (Graphical User Interface). The ZSSC324x-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 ZSSC324x located on the ZSSC324x 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 ZSC324x functionalities.

Features
I2C, SPI or OWI communication interface enables quick and
easy configuration and calibration of the ZSSC324x using the
user's computer.
Connections are provided on the ZSSC324x SSC Evaluation
Board for user's sensor module, which can be used instead
of the SSC Sensor Replacement Board.
A potentiometer on the SSC Sensor Replacement Board
controls a voltage that simulates a sensor signal ranging
from 2mV to 110mV, which can be input to the analog
frontend of the ZSSC324x (INP and INN pins) for evaluation
of basic features or for demonstrating a "dry-run" calibration.
Modular design allows reuse of kit components for evaluation
of select ZSSC324x products.
Clamshell 24-PQFN socket for ZSSC324x device under test
(DUT) facilitates testing multiple DUTs without soldering.
Software is available for download from the Renesas web site.
Note: The SSC Communication Board must have the V4.12
firmware (or higher version) in order to recognize the ZSSC324x. If
using an older Communication Board, contact Renesas regarding
firmware update procedures. For more detailed information about
the SSC Communication Board, refer to the SSC Communication
Board Data Sheet available at www.IDT.com/SSC-COMM-BD.
