ZSSC3230BI1B

Overview

The ZSSC3230BI1B is a capacitive sensor signal conditioner IC from the Renesas ZSSC3230 series, manufactured by Renesas Electronics. It is supplied as an unsawn wafer die in a gel pack, intended for surface mount device (SMD/SMT) integration. The component operates within a supply voltage range of 1.68 V to 3.6 V and supports I2C digital interface communication. Designed for low-power applications, it achieves average power consumption down to 1.3 µA at a 1 Hz conversion rate. The device features a high-precision capacitive analog front end and internal reference capabilities.

Feature Summary

• Integrates a high-precision capacitive analog front end with a CMOS integrated structure for accurate signal conditioning.
• Supports I2C digital interface for communication with host systems.
• Features an internal reference type to simplify circuit design.
• Utilizes a buck-boost architecture approach to maximize battery life in portable applications.

Applications

• Battery-driven low-power sensing technologies
• Capacitive pressure sensors
• Wearable devices requiring minimal power consumption

Procurement Notes

Verify the specific suffix 'BI1B' against official Renesas documentation to confirm the exact wafer lot and binning specifications. As this item is sold as an unsawn wafer die, ensure that your manufacturing process includes appropriate dicing and packaging capabilities. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to procurement.

Selection Notes

Select the ZSSC3230BI1B when designing systems that require direct integration of a capacitive sensor signal conditioner onto a custom substrate. This die-level package is suitable for high-volume production where final packaging is handled internally. Ensure the design environment supports the 1.68 V to 3.6 V operating voltage range and accommodates the thermal characteristics for operation between -40°C and +125°C.

Part Context

The ZSSC3230BI1B belongs to the ZSSC3230 family of Sensor Signal Conditioners (SSCs). This series is engineered for battery-powered applications, combining low-power technology with high-precision analog front ends. Other variants in the family include packaged versions like the ZSSC3230BI3W and evaluation kits such as the ZSSC3230KIT, which facilitate development before transitioning to die-level components for mass production.

Replacement Considerations

For packaged alternatives, consider the ZSSC3230BI3W, which offers the same functionality in a PQFN-24 package. For legacy designs, the ZSSC3123AI3B provides similar signal conditioning but with different voltage ranges and interface options. Verify pin compatibility and software configuration requirements when substituting these parts.
