TPS65987D: Can I use NO external SPI Flash?

TPS65987D: Eliminating the FTDI and using Aardvark adapter

Part Number: TPS65987D

Hi,

I'm designing my board from the TPS65987-90EVM circuit. The EVM board adopt an FTDI chip to configure the TPS65987D, but I'll eliminate the FTDI and place a connector which pins connect to SPI and I2C of the TPS65987D. I'm going to use the Aardvark adapter to configure through the board connector. I summarize my questions;

1. Where can I buy the Aardvark adapter?
2. Figure 23 of the SLVUAR8A document describes the I2C connection only, while the FTDI on the EVM connects both I2C and SPI. Is the I2C sufficient for the configuration and programming?
3. Figure 23 says you connect I2C port 1, while the EVM FTDI uses I2C port 2. Which is correct, I2C port 1 or 2?

Thanks again,

    Hi Jeong,

    1. You can purchase the Aardvark adapter online, just search for "Total Phase Aardvark" and you will find a buy now link

    2. You need to connect both I2C and SPI. When the boards are new, you need to program the SPI Flash over SPI.

    3. You can connect either port, if your application has both I2C1 and I2C2 as slave ports, either would work.

    Thank you,
