TDC-GP30YA 3K

Sensor And Detector Interfaces Overview

The TDC-GP30YA 3K is a system-on-chip ultrasonic flow converter manufactured by ScioSense. It integrates a 32-bit CPU, Time-to-Digital Converter (TDC), and analog frontends for direct transducer connection. The device operates on a supply voltage of 2.5 V to 3.6 V with quiescent current as low as 1.9 µA. It features 4 kByte ROM for firmware, 4 kByte NVRAM for code, and 128 x 32-bit NVRAM for data. The TDC resolution is 11 ps LSB with a measurement range up to 4096 µs. Communication interfaces include SPI (up to 10 MHz) and UART. The component is housed in a QFN-40 package.

Sensor And Detector Interfaces Feature Summary

• Integrated single-chip solution performing all flow and temperature calculations without external microcontrollers.
• Direct transducer interface capability eliminating the need for external components.
• Supports up to 31 multi-hits for high-accuracy flow measurement.
• Ultra-low power consumption enabling battery operation at 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 '3K' corresponds to the required tape-and-reel quantity of 3000 units. Confirm that the 'YA' designation matches the QFN-40 package requirement for your PCB layout. Ensure the firmware version 'no' aligns with your software integration strategy, as this variant lacks pre-loaded F01 firmware.

Sensor And Detector Interfaces Selection Notes

Select the TDC-GP30YA 3K when a QFN-40 package is preferred over the QFN-32 option. This part number indicates no pre-programmed firmware; developers must implement their own application logic using the provided ROM libraries. Verify compatibility with the target transducer frequency range, typically 1 MHz to 4 MHz, against the high-speed oscillator specifications.

Sensor And Detector Interfaces Part Context

This component belongs to the TDC-GP30 family, originally developed by acam-messelectronics GmbH and now produced by ScioSense B.V. The technical specifications remain unchanged following the commercial transfer. The 'YA' suffix specifically denotes the QFN-40 package variant, distinguishing it from the QFN-32 'YD' version.

Sensor And Detector Interfaces Replacement Considerations

The TDC-GP30YD 3K serves as a pin-compatible alternative if a smaller QFN-32 package is acceptable. Both variants share identical electrical characteristics and functionality. Ensure the footprint difference between QFN-40 and QFN-32 is addressed during hardware redesign if switching packages.
