Internal Flash Configuration

The internal flash memory can be used to store configuration parameters as shown in the following table. A free configuration utility

is provided to configure the parameters listed in the table to meet application-specific requirements over a USB interface. The

configuration utility can be downloaded at www.cypress.com/go/usbserial.

USB Configuration

Default Cypress VID. Can be configured to customer VID

Default Cypress PID. Can be configured to customer PID

Can be configured with any string up to 64 characters

Can be configured with any string up to 64 characters

Can be configured with any string up to 64 characters

Can be configured to bus-powered or self-powered mode

Can be configured to any value from 0 to 500 mA. The configuration

descriptor will be updated based on this.

Can be disabled. Remote wakeup is initiated by driving #RI low

Can be configured to function in CDC, PHDC, or Cypress vendor class

This option should be checked if we need to bypass USB regulator in

CY7C65213/CY7C65213A.

This option should be checked if we need to bypass VCCIO regulator in

CY7C65213/CY7C65213A.

This option enables an additional vendor class manufacturing mode interface

to reconfigure the CY7C65213/CY7C65213A.

Can be configured to either CMOS or LVTTL.

Can be configured to either fast or slow for EMI considerations.

Can be configured in an editable drop-down combo box that lists the

predefined, standard baud rates. You can also enter a specific baud rate in

the combo box.

This option is nor re-configurable. Pre-configured to 8 pin type.

Can be configured to either 7 bits or 8 bits.

Can be configured to either 1 bit or 2 bits.

Can be configured to either None, Odd, Even, Mark, or Space.

By selecting this option in USB Serial Configuration Utility, the polarity of the

RTS line can be inverted.

By selecting this option in USB Serial Configuration Utility, the polarity of the

CTS line can be inverted.

By selecting this option in USB Serial Configuration Utility, the polarity of the

DTR line can be inverted.

By selecting this option in USB Serial Configuration Utility, the polarity of the

DSR line can be inverted.

By selecting this option in USB Serial Configuration Utility, the polarity of the

DCD line can be inverted.

By selecting this option in USB Serial Configuration Utility, the polarity of the

RI line can be inverted.

This parameter defines the behavior of the UART when an error is detected

in the packet received (RX packet/byte). When this option is selected in USB

Serial Configuration Utility, the data packet/byte in the RX buffer is discarded.
