The SSC Evaluation Kit provides the hardware needed for communication and calibration of the ZSSC3170
sensor signal conditioning (SSC) IC. A PC can communicate with the ZSSC3170 SSC Evaluation Board via the
SSC Communication Board (CB) through a USB connection. The software should function on any Windows®
2000/XP/ Vista / Windows® 7/Windows® 8 system after the installation of a USB driver.
The Sensor Replacement Board (SRB) provides a replacement for an actual sensor and can be used for the first
step of calibration or a dry-run calibration as described in section 4. On the SRB, the sensor replacement signal is
controlled by a potentiometer (see Figure 1.1).

ZSSC3170 Evaluation Board
Overview
ZSSC3170 SSC Evaluation Board – Overview
Figure 2.1
The main purpose of the SSC Evaluation Kit is to perform communication between the user’s PC and the
ZSSC3170 (referred to as the DUT). The PC sends commands and data via the USB port on the CB (virtual COM
2
†
port). The microcontroller on the CB interprets these commands and relays them to the DUT in the I C™ or LIN
communication mode (via connector K1; see Figure 2.1). The microcontroller also forwards any data bytes from
the DUT back to the PC via the USB connection. These bytes can be bridge and temperature readings to be
displayed by the ZSSC3170 SSC Evaluation Kit software or raw ADC readings used during calibration or
EEPROM content bytes.
The SSC CB microcontroller controls the power signals required for entering the Command Mode, and it is able to
read the PWM output signal of ZSSC3170 and send this value back to PC. Because the ZSSC3170 provides a
high and low side switch PWM signal, an inverted LIN communication protocol is also required. This is generated
automatically by the SSC EB and controlled via the SSC CB.
