FTDI FT232R USB to UART Interface IC SSOP28 Package

The FTDI FT232R USB to UART Interface IC is a 28-pin SSOP28 integrated circuit that provides a complete single-chip solution for converting USB to asynchronous serial data. It removes much of the complexity usually associated with USB to serial designs.

Overview

The FT232R is the latest device in FTDI's USB UART interface range. It handles the entire USB protocol on-chip, so no USB-specific firmware programming is required from the user. The chip integrates the EEPROM used for device configuration, the clock circuit, and the necessary USB resistors, which simplifies board layout and reduces the bill of materials.

Key Features

• FTDIChip-ID security dongle capability for enhanced device authentication and security
• Flexible UART interface supporting 7 or 8 data bits, 1 or 2 stop bits, and odd, even, mark, space, or no parity
• Hardware handshaking or X-On/X-Off software handshaking for reliable data flow control
• In-built support for event characters and line break conditions
• Configurable CBUS I/O pins providing additional GPIO functionality
• Auto transmit buffer control for RS485 networks
• Dedicated transmit and receive LED drive signals
• Clock outputs at 48MHz, 24MHz, 12MHz, and 6MHz for driving an external MCU or FPGA

Specifications

• Bridge type: USB to UART
• Supply voltage: 1.8V to 5.25V
• Operating temperature: -40°C to +85°C
• Package: SSOP (Shrink Small-Outline Package), 28 pins
• Moisture sensitivity level: MSL 3 - 168 hours
• Dimensions (width x depth x height): 3.3 x 1.5 x 4.3
• Weight: 0.426 g

Applications

The FT232R is suited to industrial applications, including RS485 network designs, and to any USB design that needs conversion to asynchronous serial communication. Its configurable CBUS pins and clock outputs also support designs where an external MCU or FPGA must be driven from the same device.
