2.2 Basic Operation

The PGA450-Q1 device can operate from either OTP or DEVRAM memory, and from the LIN, UART, or SPI communication interfaces. Because of the various methods of operation, the configuration of OTP memory and UART communication for initial evaluation, development, and debug is used as the basic operation example throughout this document. To burst and capture an ultrasonic profile, the user must connect a 5-V logic-level compatible UART-to-USB interface device, and send the corresponding commands discussed in Section 2.3. The details of this section are limited to the minimum requirements because this user's guide assumes that the user has fully evaluated the PGA450Q1EVM, which provides more extensive and elaborate details.
