== ISO/TS16949==
• Microchip products meet the specification contained in their particular Microchip Data Sheet.
• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
• Microchip is willing to work with the customer who is concerned about the integrity of their code.
• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”

Chapter 1. Product Overview
1.1 INTRODUCTION
This chapter discusses the following topics:
• HV7351 Device Overview
• Board Overview
• What the HV7351 Ultrasound Tx Beamformer Evaluation Board Kit Includes
1.2 HV7351 DEVICE OVERVIEW
The Microchip Technology Inc. HV7351 is a monolithic, eight channel, high-speed,
high-voltage ultrasound transmitter Return-To-Zero (RTZ) programmable pulser. This
integrated, high-performance circuit comes in a single 11 x 11 x 0.9 mm, 80-lead DFN
package.
Each channel is capable of swinging up to ±70V with an active discharge back to 0V.
The outputs can source and sink more than 3A to achieve fast output rise and fall times.
The active discharge is also capable of sourcing and sinking 3A for a fast return to
ground. The digital beamforming topology of the HV7351 will significantly reduce the
number of I/O logic control lines to the transmitter.
Each output is controlled by a 16 or 32-bit serial shift register. An arbitrary pattern can
be generated depending on what is loaded into the shift registers, including four
independent pattern options.
Once the patterns are loaded, the user can quickly select any of the four predefined
patterns without having to clock in new data. A programmable 10-bit delay counter is
provided for each output. This allows the user to program different delay times for each
channel for beamforming.

EVALUATION BOARD USER’S GUIDE
1.3 BOARD OVERVIEW
There are two built-in Complex Programmable Logic Devices (CPLDs) and one serial
EEPROM on the board to provide multiple demo waveform patterns. Other custom
experimental data can be easily downloaded to these CPLDs/PROMs via the 6-pin
Joint Test Action Group (JTAG) interface.
The HV7351 Board output waveforms can be directly displayed using an oscilloscope,
by connecting the scope probe to the test points TX1 - TX8 and GND. The soldering
jumper can select whether or not to connect the on-board dummy-load, a 330 pF
capacitor paralleling with a 2.5 k resistor. The test points can be used to connect the
user’s transducer to easily evaluate the pulser.
