STHVUP64

Overview

The STHVUP64 is a monolithic 64-channel high-voltage and high-speed ultrasound pulser with an integrated transmit beamformer, designed for low-power ultra-portable medical imaging. It generates ±100 V waveforms in 3-level or 5-level configurations. Peak output currents are programmable to ±400 mA (3-level) or ±200 mA (5-level). The device features fully integrated 45 Ω transmitting/receiving switches and ground clamping circuits. A digital core operates at up to 200 MHz, managing delay profiles and waveform generation via embedded memory storing up to 32 states.

Procurement Notes

Verify the specific package variant against the datasheet, as local listings may indicate bulk packaging while official documentation specifies tray packing. Confirm that the ordering suffix matches the required thermal and mechanical specifications for the target application environment.

Selection Notes

Select this component for designs requiring high integration of beamforming logic and high-voltage pulsing in a small footprint. Ensure the system power budget accommodates the peak current requirements of the chosen 3-level or 5-level mode. Verify compatibility with the QSPI interface for control signals.

Part Context

This part belongs to STMicroelectronics' STHVUP series of ultrasound transmitters. It utilizes proprietary BCD6s-SOI technology to combine high-voltage power stages with low-voltage CMOS logic on a single chip, enabling compact solutions for point-of-care diagnostic devices.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative ST models within the STHVUP family based on channel count and voltage ratings if direct replacement is necessary.
