ZSSC3170EA3R

Overview

The ZSSC3170EA3R is a CMOS integrated circuit designed for highly accurate amplification and sensor-specific correction of resistive bridge sensor signals. It features a maximum analog gain of 420 and extended offset compensation capabilities, making it suitable for nearly all resistive bridge sensor types. The device utilizes a 16-bit RISC microcontroller to perform digital compensation of offset, sensitivity, temperature drift, and nonlinearity up to the third order. Conditioning coefficients are stored in an automotive-certified EEPROM. Measured values are provided via digital LIN or PWM interfaces, which support end-of-line calibration. The component operates within a supply voltage range of 7V to 18V and supports an operating temperature range from -40°C to 125°C.

Feature Summary

• Digital compensation of offset, gain, temperature effects, and nonlinearity using a 16-bit RISC microcontroller
• Configurable LIN publisher frame content compliant with LIN specifications 1.3, 2.0, and 2.1
• Internal or external temperature reference capability for media temperature sensing
• Load-dump protection on the LIN pin up to ±40V

Applications

• Automotive sensor signal conditioning
• Resistive bridge sensor interface
• End-of-line calibration systems

Procurement Notes

Verify the specific suffix EA3R against official Renesas documentation to confirm package type and availability status. Note that this part number may be listed as obsolete in some distributor catalogs; cross-reference with current Renesas product lifecycle data to ensure long-term supply viability before finalizing design-in decisions.

Selection Notes

Select this component when designing automotive applications requiring precise digital compensation for resistive sensors. Ensure the system architecture supports LIN or PWM communication protocols. Verify that the required accuracy levels align with the specified FSO tolerances across the intended operating temperature range. Confirm compatibility with the ZSSC3170KIT evaluation hardware if prototyping is required.

Part Context

The ZSSC3170 series represents Renesas' specialized sensor signal conditioner family aimed at simplifying IoT and automotive sensor integration. These ICs reduce design complexity by handling amplification and correction internally, allowing designers to focus on system-level integration rather than complex driver code development for individual sensor types.
