ZSSC3135BE1D

Overview

The ZSSC3135BE1D is a sensor signal conditioner from the ZSSC313x family, designed for automotive and industrial piezoresistive bridge sensors. It features an analog gain of 105 and supports sample rates up to 200Hz with 13/14-bit ADC resolution. The device includes a 16-bit RISC microcontroller for digital compensation of offset, sensitivity, temperature drift, and nonlinearity. Calibration coefficients are stored in on-chip EEPROM via single-pass calibration. Output options include ratiometric analog voltage (5% to 95%, 12.4-bit resolution) or ZACwire™ digital one-wire interface. Supply current is max 5.5mA, with operation temperature range -40°C to +150°C.

Feature Summary

• Internal 16-bit RISC microcontroller performs real-time digital correction of sensor errors including offset, sensitivity, temperature drift, and nonlinearity.
• Supports single-pass calibration procedure storing coefficients in on-chip EEPROM for traceability.
• Provides high-voltage protection up to 33V along with reverse polarity and short circuit protection capabilities.

Applications

• Automotive pressure and force sensing applications requiring high accuracy.
• Industrial sensor interfaces utilizing piezoresistive bridge elements.
• Cost-optimized switch applications needing fast switching or stabilized input signals.

Procurement Notes

Verify component authenticity through authorized Renesas distributors. Confirm package type matches BE1D designation (Dice Wafer Sawn). Check revision history for any functional updates. Ensure storage conditions comply with moisture sensitivity level requirements. Validate supply chain documentation against official Renesas part number records.

Selection Notes

Select ZSSC3135BE1D when piezoresistive sensor compensation is required. Choose this model over ZSSC3131 if external temperature sensor support is needed for enhanced drift compensation. Consider ZACwire interface for digital output systems. Verify analog gain requirements match the 105x specification. Ensure operating temperature range covers -40°C to +150°C application needs.

Part Context

The ZSSC3135 belongs to the ZSSC313x product family of CMOS integrated circuits. This family targets highly accurate amplification and sensor-specific correction for resistive bridge sensors. The ZSSC3135 variant specifically emphasizes compatibility with piezoresistive elements through its dedicated analog gain stage and optional external temperature compensation architecture.

Replacement Considerations

ZSSC3135BA1B is an obsolete wafer-level alternative within the same family. No direct pin-compatible replacements are documented. Evaluate ZSSC3131 for cost-sensitive switch applications lacking external temperature sensor requirements. Verify functional equivalence before substitution.
