33 / 43 page  Copyright © 2010 Future Technology Devices International Limited 33 Document No.: FT_000053 FT232R USB UART IC Datasheet Version 2.07 Clearance No.: FTDI# 38 8 Internal EEPROM Configuration Following a power-on reset or a USB reset the FT232R will scan its internal EEPROM and read the USB configuration descriptors stored there. The default factory programmed values of the internal EEPROM are shown in Table 8.1. Parameter Value Notes USB Vendor ID (VID) 0403h FTDI default VID (hex) USB Product UD (PID) 6001h FTDI default PID (hex) Serial Number Enabled? Yes Serial Number See Note A unique serial number is generated and programmed into the EEPROM during device final test. Pull down I/O Pins in USB Suspend Disabled Enabling this option will make the device pull down on the UART interface lines when in USB suspend mode (PWREN# is high). Manufacturer Name FTDI Product Description FT232R USB UART Max Bus Power Current 90mA Power Source Bus Powered Device Type FT232R USB Version 0200 Returns USB 2.0 device description to the host. Note: The device is a USB 2.0 Full Speed device (12Mb/s) as opposed to a USB 2.0 High Speed device (480Mb/s). Remote Wake Up Enabled Taking RI# low will wake up the USB host controller from suspend in approximately 20 ms. High Current I/Os Disabled Enables the high drive level on the UART and CBUS I/O pins. Load VCP Driver Enabled Makes the device load the VCP driver interface for the device. CBUS0 TXLED# Default configuration of CBUS0 – Transmit LED drive. CBUS1 RXLED# Default configuration of CBUS1 – Receive LED drive. CBUS2 TXDEN Default configuration of CBUS2 – Transmit data enable for RS485 CBUS3 PWREN# Default configuration of CBUS3 – Power enable. Low after USB enumeration, high during USB suspend mode. |
