ZSSC3240CC1C

Overview

The ZSSC3240CC1C is a sensor signal conditioning IC designed for resistive bridge sensors. It features a programmable measurement sequencer that multiplexes between bridge, temperature, and diagnostic measurements. The device provides offset compensation and amplification with a gain factor up to 540V/V to optimize the ADC input range. It digitizes signals up to 24-bit resolution and uses an internal DSP for linearization and temperature compensation. Output interfaces include SPI, I2C, and 1-Wire. The analog output resolution is programmable up to 16 bits. Operating voltage ranges from 1.8V to 3.6V. Supply current is typically 2.8mA. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Supports digital compensation for sensor offset, sensitivity, temperature drift, and non-linearity via a 26-bit math core.
• Provides flexible output options including absolute or ratiometric analog voltage and standard industrial current loop.
• Includes on-chip diagnostics and self-diagnostic coverage for system safety.

Applications

• Pressure sensors
• Industrial sensing platforms
• Resistive bridge sensor interfaces

Procurement Notes

Verify the specific suffix 'CC1C' against official Renesas documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB layouts as the ZSSC3240 series maintains consistent pad layouts across variants. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before final procurement.

Selection Notes

Select the ZSSC3240CC1C when high-accuracy signal conditioning for resistive sensors is required. It is suitable for applications needing both digital and analog outputs. Compare with the ZSSC3241 if additional AFE configuration options or backward compatibility with ZSSC3240 features are not needed. Consider power consumption requirements relative to the 2.8mA typical supply current.

Part Context

The ZSSC3240 is part of Renesas' Sensor Signal Conditioning (SSC) portfolio. It is designed for easy sensor platform development in the rapidly growing sensing industry. The device sets standards for performance and flexibility. It is often used in conjunction with external resistive sensor elements to create complete sensing solutions.

Replacement Considerations

The ZSSC3241 is noted as being 99% backward compatible to the ZSSC3240. Verify pinout and EEPROM differences if substituting. No other direct public substitutes are confirmed in the provided data.
