Q: I'm interested in buying some of your products, but I have a few questions. First, is there any memory in any of your products that would retain information when powered down? If the answer to this is yes, I have another question – is there a sanitization procedure for these devices that can be performed after using a classified processing system?

A: Thanks for your question! To answer your questions, we'll first give a little background on what types of products are manufactured by Total Phase.

• Total Phase offers three types of products – protocol analyzers, host adapters, and CAN interfaces. Protocol analyzers are passive monitoring tools. When the protocol analyzer is hooked up to a USB, I2C, or SPI bus, data between the bus and target device is monitored and displayed for the developer to analyze immediately. Users have the option of saving the trace to their computer hard drive, no data is saved to the PC unless specified by the user.
• Host adapters are active programming tools with master and/or slave capabilities. Engineers can actively communicate over the I2C or SPI bus by reading and writing messages, programming batch commands, and more. While users can enter data into our GUIs or load batch files, no data is saved to the PC unless specified by the user.
• The last type of product we offer is the CAN interface. The CAN interface is an all-in-one tool that allows engineers to perform active CAN data transmission and passive CAN data monitoring. Like protocol analyzers and host adapters, while users can enter data into our GUIs or load batch files, no data is saved to the PC unless specified by the user.

Now that we've gone through a rundown of all the Total Phase products, let's discuss your question about memory. For all of our products – host adapter, protocol analyzer, CAN interfaces – and for all protocols – USB, I2C, SPI, CAN – user data is never stored in non-volatile memory. Once the device is powered down, the contents of the volatile memory lost. Thus, no sanitization procedure is required.

If you have any need for a letter of volatility to present to your colleagues regarding any of our tools' memory storage, please email us at sales@totalphase.com to request one.

We hope this answers your questions about the memory in our products! If you have any questions, feel free to email us at sales@totalphase.com or support@totalphase.com.
