ZSSC4151CE5R

Overview

The ZSSC4151CE5R is a sensor signal conditioner manufactured by Renesas Electronics, designed for resistive bridge sensors. It features an internal 16-bit RISC microcontroller that performs digital compensation for offset, sensitivity, temperature drift, and nonlinearity, with coefficients stored in integrated EEPROM. The device supports I2C and ZACwire™ (OWI) interfaces and provides a ratiometric analog voltage output. It operates on a supply voltage of 4.5 V to 5.5 V, consumes up to 7 mA, and functions within a temperature range of -40°C to +150°C. The component is housed in a 16-TSSOP package.

Feature Summary

• Digital compensation for sensor offset, sensitivity, temperature drift, and nonlinearity via internal microcontroller
• Supports I2C and ZACwire™ (OWI) digital interfaces alongside analog output
• High-voltage tolerant pins (VDDE, VSSE, AOUT) with reverse polarity protection
• Internal or external temperature compensation options

Applications

• Automotive pressure sensors
• Automotive temperature sensors
• Industrial load cells
• Resistive bridge sensor conditioning

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm package type and tape/reel specifications. Ensure compatibility with automotive qualification standards such as AEC-Q100 if required for the application. Confirm availability through authorized distributors as lead times may vary.

Selection Notes

Select this component when digital calibration is preferred over analog trimming to reduce assembly costs. It is suitable for applications requiring high accuracy across wide temperature ranges. Consider the available interface options (I2C/OWI) and the need for analog output flexibility when designing the system architecture.

Part Context

The ZSSC4151 series includes variants like CE5T, CE1C, CE6R, and CE4R, offering different packaging options such as TSSOP-16, Die, and QFN-24. The CE5R variant specifically denotes a tape and reel configuration of the standard sensor signal conditioner, maintaining the core functionality of the family while adapting to automated surface-mount assembly processes.

Replacement Considerations

Direct substitutes are not explicitly listed in public data. Evaluate other members of the ZSSC4151 family (e.g., ZSSC4151CE6R) for pin-compatible alternatives if package differences are critical. Verify functional equivalence regarding interface protocols and compensation algorithms before substitution.
