TDC-GP30YD-F01 1K

Sensor And Detector Interfaces Overview

The TDC-GP30YD-F01 1K is a system-on-chip ultrasonic flow converter manufactured by ScioSense. It integrates a 32-bit CPU, Time-to-Digital Converter (TDC), and analog front-end within a QFN-32 package. The device supports supply voltages from 2.5 V to 3.6 V and operates across an ambient temperature range of -40°C to +85°C. Key electrical parameters include a quiescent current of 1.9 µA with clocks off and a typical standby current of 2.2 µA at 3.0 V. The TDC resolution is 11 ps LSB with a measurement range up to 4096 µs for time-of-flight applications.

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm firmware inclusion and packaging quantity. Confirm that the QFN-32 package dimensions and pinout match the target PCB footprint. Ensure compliance with RoHS directives and check for any recent Product Change Notifications regarding material or process updates before finalizing procurement.

Sensor And Detector Interfaces Selection Notes

Select this component when a compact, single-chip ultrasonic flow conversion solution is required. The integrated CPU and NVRAM reduce external component count compared to two-chip solutions. Verify that the operating voltage range and interface requirements align with the host system design. Consider the thermal resistance and soldering profile constraints associated with the QFN-32 package during layout.

Sensor And Detector Interfaces Part Context

This part belongs to the TDC-GP30 family, which represents the next generation of ultrasonic flow converters previously developed by acam-messelectronics GmbH. The product line is designed to simplify the design of ultrasonic heat and water meters by performing all flow and temperature calculations on-chip. The 'YD' designation indicates the QFN-32 package variant.

Sensor And Detector Interfaces Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult ScioSense directly for alternative components or updated versions within the GP30 family if this specific SKU becomes obsolete.
