ZSC31010CEC

Overview

The ZSC31010CEC is a CMOS integrated circuit sensor interface die from Renesas Electronics, designed for resistive bridge sensors. It provides digital compensation for offset, sensitivity, temperature drift, and non-linearity via EEPROM calibration. The device accommodates differential signal spans from 3 mV/V to 105 mV/V with an adjustable analog gain of 6, 12, 24, or 48. It features a 14-bit resolution and a maximum sample rate of 1 kHz. Supply voltage ranges from 2.7 V to 5.5 V, extending to 30 V with an external JFET. Current consumption varies between 0.25 mA and 1 mA depending on the sample rate. The operational temperature range is -40°C to +85°C.

Feature Summary

• Digital compensation of sensor offset, sensitivity, temperature drift, and non-linearity
• ZACwire one-wire serial interface for host communication and mass calibration
• Internal temperature detection using bandgap PTAT with optional sequential output
• Selectable output modes including ratiometric analog voltage, absolute analog voltage, and digital data

Applications

• Industrial pressure sensors
• Force and torque measurement systems
• Automotive HVAC sensor interfaces

Procurement Notes

Verify the specific suffix 'CEC' against official Renesas documentation to confirm it denotes the wafer sawn die format in a frame. Confirm that the package type matches your assembly process requirements. Check current availability status as distribution may vary. Ensure the operating temperature range meets your application's environmental specifications before finalizing procurement.

Selection Notes

Select this component when precise digital calibration of resistive bridge sensors is required without external microcontrollers. It is suitable for applications needing high accuracy over wide temperature ranges. Consider the ZACwire interface compatibility with your host system. Evaluate if the 14-bit resolution and 1 kHz sampling rate meet your dynamic response needs.

Part Context

The ZSC31010 series belongs to Renesas' ZACwire SSC family, offering modular sensor signal conditioning. The CEC suffix typically indicates the die form factor, distinguishing it from packaged variants like SSOP. This family integrates amplification, ADC, and digital correction algorithms into a single CMOS IC, simplifying sensor design by handling non-linearities digitally.

Replacement Considerations

Publicly confirmed direct substitutes are not available in the provided source material. For equivalent functionality, consider other members of the ZSC310xx series or ZSSC family, such as the ZSC31015 or ZSC31050, after verifying pinout and feature compatibility with official datasheets.
