STEVAL-IME016A [STMicroelectronics]

The STEVAL-IME016A is an evaluation kit demonstrating the STHVUP32 performances.

The STHVUP32 is a 32-channel monolithic high-voltage and high-speed pulser with an integrated beamformer.

The STHVUP32 is specifically designed for pulse generation in multichannel low-power and ultraportable medical ultrasound applications.

The waveforms generated by STHVUP32 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 STHVUP32 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 STHVUP32.

There are also programming, start and reset buttons, and a GUI is provided to facilitate demo-kit programming operations.

• Power lift gate features:
  • 32-channel high-voltage output (XDCR)
  • 32-channel low-voltage output (LVOUT)
  • No loads on XDCR and LVOUT
  • USB connector to change programs and waveforms
  • Button interface to program, start and stop the generation of the waveforms
  • LEDs to monitor STHVUP32 behavior
  • System based on STM32
• 2-layers (modules) staked:
  • STM32 Nucleo-32 board
  • STHVUP32 module
  • Low-voltage supplies generated on board
  • Only one external supply is needed (7-12 V) for LV supply rails generation
  • Dedicated connector for the four high-voltage supply rails
  • GUI or textual interface to configure STEVAL-IME016A by yourself
