TDC-GP30YA 1K

Sensor And Detector Interfaces Overview

The TDC-GP30YA 1K is a system-on-chip ultrasonic flow converter manufactured by ScioSense. It integrates a 32-bit CPU, analog front-end, and time-to-digital converter within a 40-pin QFN package (6x6 mm). The device operates on a supply voltage of 2.5 to 3.6 V with a typical quiescent current of 1.9 µA. Key specifications include a TDC resolution of 11 ps LSB, a measurement range up to 4096 µs for TOF, and support for SPI and UART interfaces. It features 4k x 8 bit ROM and NVRAM for firmware storage.

Sensor And Detector Interfaces Feature Summary

• Integrates high-precision analog frontend and digital signal processing for direct transducer connection without external components.
• Supports MID-compliant flow and temperature calculations using internal firmware libraries.
• Enables ultra-low power operation suitable for battery-powered applications with standard measuring frequencies.

Sensor And Detector Interfaces Applications

• Ultrasonic heat meters
• Ultrasonic water meters
• Industrial flow metering systems

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm firmware inclusion and packaging quantity. Confirm that the component meets RoHS compliance requirements for your region. Check for any product change notifications regarding material or pinout modifications before finalizing procurement plans.

Sensor And Detector Interfaces Selection Notes

Select this variant when a 40-pin QFN package is required for the design. Ensure the application does not require pre-loaded firmware, as this part number indicates no firmware. Verify interface compatibility with SPI or UART protocols and confirm operating temperature ranges align with the -40°C to +85°C specification.

Sensor And Detector Interfaces Part Context

This component belongs to the TDC-GP30 family of ultrasonic flow converters. It represents a system-integrated solution designed to replace traditional two-chip architectures. The 'YA' designation specifically identifies the QFN40 package variant within the series.

Sensor And Detector Interfaces Replacement Considerations

Direct replacements are limited due to the integrated nature of the chip. Consider the TDC-GP30YD 1K if a QFN32 package is acceptable and firmware is not required. Verify pinout compatibility and software migration efforts before substituting.
