Difference between CY7C6521x and PSoC 4 with USB-CDC + UART SCB?

[DaEr_349131]

For pure UART to USB-CDC bridging,

• are there any differences between a CY7C65213 vs PSoC 4 with a USB-CDC + UART SCB component?

Hello,

The USB-Serial device CY7C65213 is a fixed firmware part with a single SCB. It supports UART under CDC and vendor mode and can be easily configured using the USB-Serial Configuration Utility where PSoC 4 device has more features including 2 SCBs which are individually configurable.

Both the device can implement CDC.

Please refer to the Data sheet of both the parts and you can compare the UART interface in both of them.

HI Yatheesh,

Yes, we're familiar with both. Just curious if the UART block in the PSoC4 is the same (feature-set) as the CY7C6xx parts?

Related: Can you help comment if the CY7C65213 supports "run-time" configuration for setting different baud-rates and such (via say a separate USB-CDC or HID endpoint)

Hello,

The UART blocks on the two parts are different.

->

The CY7C65213 can be configured to work in UART CDC and UART Vendor mode.

In CDC mode you can use standard application like the tera term to configure the baud rates dynamically.

If you are using UART under vendor mode, we provide APIs to set the required configuration for UART, this can be used in your application.

You can refer to the USB-Serial API documentation in this link: https://www.cypress.com/file/123321/download
