1 Evaluation Kit Contents and Overview
The ZSSC4151 SSC Evaluation Kit is designed for sensor module evaluation, laboratory setup, and module
calibration development for the ZSSC4151 Sensor Signal Conditioner (SSC). The user’s sensor module can be
connected to the kit for development, evaluation, and calibration. Alternately, the kit provides a sensor
replacement board that can be connected in place of an actual sensor module for basic evaluation purposes only.
The ZSSC4151 Evaluation Kit consists of the following parts:
•SSC Communication Board (SSC CB) V4.1 *
•ZSSC415x/6x/7x SSC Evaluation Board (SSC EB) V1.1
•SSC Sensor Replacement Board (SRB) V2.0
•6 ZSSC4151 samples (QFN24 4x4mm)
•USB cable
•Vacuum suction pen (provided for safe handling of IC samples)
Note: The ZSSC4151 Evaluation Software required for the ZSSC4151 SSC Evaluation Kit is not included with the
kit. This software is available for download from the ZSSC415x product page or by contacting IDT (for contact
information, see page 10). It provides a graphical user interface (GUI) for communication, calibration, and
evaluation. Refer to the ZSSC4151 Evaluation Kit Startup Guide for instructions for setting up the kit hardware,
connections, and software.
Note: The ZSSC415x/6x/7x SSC Evaluation Board is also used in kits for other products, so some of the
ZSSC4151 pin names differ from the board and schematic labels. See Table 2.4 for the corresponding pin names.
Note: There is a “dummy” IC in the socket on the ZSSC415x/6x/7x SSC Evaluation Board that should be replaced
with an actual ZSSC4151 device under test (DUT). Refer to Figure 1.1 for the location of pin 1 for proper IC
orientation.

The ZSSC4151 SSC Evaluation Kit contains the hardware needed for communication and calibration of the
ZSSC4151 sensor signal conditioning IC. The user’s PC can communicate with the ZSSC4151 on the SSC EB
via the SSC Communication Board (SSC CB) through a USB connection. The Sensor Replacement Board (SRB)
provides a replacement for an actual sensor and can be used for the first step of a calibration demonstration or a
dry-run calibration. On the SRB, the sensor replacement signal is controlled by a potentiometer and provides a
signal ranging from 2mV to 110mV to the analog front-end of the ZSSC4151 (BRN and BRP pins via the BR1N
and BR1P pins respectively on the K10 connector; see Figure 2.2) and a temperature sensor signal from a
1N4148 diode to the ZSSC4151 temperature input (TS1 or TS2 pin, selectable by jumper K8, see Figure 2.1).
One of the primary purposes of the ZSSC4151 Evaluation Kit is communication between the user’s PC and the
ZSSC4151 DUT. The PC sends commands and data via its USB port (configured as a virtual COM port) to the
SSC CB. The microcontroller on the SSC CB interprets these commands and relays them to the ZSSC4151 in the
I²C™*or OWI†(One-Wire Interface) communication mode.
The microcontroller will also forward any data bytes from the ZSSC4151 back to the PC via the USB connection.
These bytes can be sensor and temperature readings to be displayed via the GUI, raw analog-to-digital converter
(ADC) data used during calibration, or EEPROM data. The SSC CB microcontroller controls the power signals
required for entering the Command Mode (when the OWI interface is used).
The ZSSC4151 power (VDDE) can be supplied from the CB KS5V power supply (jumper K7 closed; refer to
Figure 2.1) or from an externally connected VDDE2 supply (jumper K7 open).
Important: Ensure that jumper K7 is open before connecting an external VDDE2 power supply.
If connected, the VDDE2 supply can be switched ON or OFF by the CB-controlled KS5V and the IC4 power
MOSFET as needed to establish OWI communication.
The reset button (see Figure 1.1) initializes the CB controller to its initial state. Note that any CB port settings
will be overwritten.
The Mass Calibration Board DUT connector is intended for connecting the ZSSC415x/6x/7x Evaluation Board
(SSC EB) to a Mass Calibration Board (MCB) for evaluation. The connector provides an I2C™ and OWI interface
through the MCB and provides power to it.
Important: Do not connect the SSC CB to the SSC EB if the MCB is used.
*I2C™ is a trademark of NXP.
†OWI is also referred to as ZACwire™.
