ZSSC4169DE5R-APC

Overview

The ZSSC4169DE5R-APC is an automotive-grade sensor signal conditioning IC from the Renesas ZSSC416x series. It provides high-precision amplification and digital correction for differential bridge sensors, supporting a maximum analog gain range of 2.1 to 200. The device features a 14-bit resolution with a maximum sample rate of 1.3 kHz and operates on a supply voltage of 4.75 V to 5.25 V. It integrates a 16-bit RISC microcontroller for offset, sensitivity, temperature drift, and nonlinearity compensation, storing calibration data in non-volatile memory. Communication interfaces include SENT and I2C.

Feature Summary

• Integrated digital compensation for offset, sensitivity, temperature drift, and nonlinearity using an embedded 16-bit RISC microcontroller.
• Supports both fast-channel SENT output for primary sensor data and I2C interface for configuration and offline calibration.
• Includes integrated non-volatile memory (NVM) for reliable storage of calibration coefficients and configuration data in automotive environments.
• Optimized for automotive applications with overvoltage protection, reverse polarity protection, and robust electromagnetic compatibility.

Applications

• Automotive pressure sensors
• Automotive temperature sensors
• Automotive acceleration sensors

Procurement Notes

Verify the specific suffix 'E5' against official Renesas documentation to confirm pinout and package compatibility, as variations exist within the ZSSC416x family. Confirm availability status directly with authorized distributors, as automotive components may have limited stock or long lead times. Ensure the selected variant matches the required interface (SENT/I2C) and packaging type for your design.

Selection Notes

Select this component when designing systems requiring high accuracy for resistive bridge sensors without external trimming. The integrated digital calibration reduces assembly costs by eliminating the need for external calibration equipment. Ensure the application requires SENT or I2C output and operates within the specified -40°C to +150°C temperature range.

Part Context

The ZSSC4169 belongs to the ZSSC416x/ZSSC417x series of sensor signal conditioners designed for automotive IoT applications. These devices complement Renesas' MCU portfolio by handling precise sensor signal acquisition and conditioning, enabling faster design cycles and improved system accuracy for connected vehicle solutions.

Replacement Considerations

Check for other members of the ZSSC416x series, such as ZSSC4161 or ZSSC4169 variants with different suffixes, which may offer similar functionality but potentially different interfaces or packages. Verify functional equivalence before substitution.
