ZSSC3281BI5B

Overview

The ZSSC3281BI5B is a sensor signal conditioner from Renesas Electronics, designed for Industrial Internet of Things (IIoT) applications. It integrates an Arm Cortex-M3 core operating at 16MHz with 64kByte flash memory. The device features two fully independent analog front ends (AFE), each including an input switch matrix, programmable gain amplifier with offset correction, and a high-resolution ADC supporting up to 24 bits. It supports calibration using up to four temperature sources and processes three independent temperature channels alongside two main sensor channels.

Feature Summary

• Integrates an Arm Cortex-M3 microprocessor core for digital processing and code conversion
• Features dual independent analog front ends with high-resolution analog-to-digital conversion capabilities
• Supports flexible calibration using multiple onboard and external temperature sources

Applications

• Industrial Internet of Things (IIoT) smart sensors
• Temperature sensing systems
• Pressure measurement devices
• Flow and level sensing instruments
• Weight measurement systems

Procurement Notes

Verify the specific suffix 'BI5B' against official Renesas documentation to confirm package type and environmental compliance. Confirm availability status as supply may be limited or subject to factory special orders. Ensure the selected variant matches the required interface and performance specifications for the target design.

Selection Notes

Select this component when designing smart sensors requiring integrated signal conditioning and processing. Consider the 24-bit ADC resolution and dual AFE architecture for high-precision applications. Evaluate the 16MHz Cortex-M3 core capacity for required algorithm complexity. Verify thermal management requirements given the on-chip temperature calibration features.
