STMicroelectronics STHVUP64 | Demoboard STEVAL-IME017A

Beschreibung

STEVAL-IME017A is an evaluation kit that demonstrates STHVUP64 performances, a 64-channel monolithic high-voltage and high-speed pulser with an integrated beamformer.STHVUP64 is specifically designed for pulse generation in multichannel low-power and ultraportable medical ultrasound applications.The waveforms generated by STHVUP64 are described with sequences of up to 32 states stored in the device memory. With each state it is possible to configure each individual output channel to be connected to high-voltage supplies (positive or negative), clamped to the ground, or left in high-impedance. The STHVUP64 also embeds a digital core that manages the delay profile used in the beamformer of the channels.For demonstration purposes, dedicated connectors have been added to which the probes of an oscilloscope or an analog front-end can be connected to display or process the high-voltage signals generated by the STHVUP64. There are also programming, start and reset buttons, and a GUI is provided to facilitate demo-kit programming operations.
