Introduction

AI Translation

The FT232R is a USB to serial UART interface with optional clock generator output, and the new FTDIChip-ID security dongle feature. In addition, asynchronous and synchronous bit bang interface modes are available. USB to serial designs using the FT232R have been further simplified by fully integrating the external EEPROM, clock circuit and USB resistors onto the device. The FT232R adds two new functions compared with its predecessors, effectively making it a “3-in-1” chip for some application areas. The internally generated clock (6MHz, 12MHz, 24MHz, and 48MHz) can be brought out of the device and used to drive a microcontroller or external logic. A unique number (the FTDIChip-ID) is burnt into the device during manufacture and is readable over USB, thus forming the basis of a security dongle which can be used to protect customer application software from being copied. The FT232R is available in Pb-free (RoHS compliant) compact 28-Lead SSOP and QFN-32 packages.

Product FAQ

  • 1. What core interface translation features and integrated peripheral functions define the FT232RL-REEL?
    The FT232RL-REEL is a single-chip USB 2.0 Full Speed (12 Mbps) to asynchronous serial data (UART) interface IC. It features a fully integrated 1024-bit internal EEPROM for storing USB VID, PID, serial number, product description strings, and configuration descriptors, an integrated 12 MHz oscillator that eliminates the need for an external crystal, and configurable clock output options of 6 MHz, 12 MHz, 24 MHz, and 48 MHz. The device supports asynchronous data transfer rates from 300 baud up to 3 Mbaud at TTL/CMOS levels and includes a 256-byte receive FIFO buffer and a 128-byte transmit FIFO buffer for high data throughput.
  • 2. What input supply ranges, power consumption profiles, and flexible logic levels govern IC operation?
    The device operates from a single main supply voltage (VCC) of 3.3 V to 5.25 V, with a typical operating current of 15 mA and a typical USB suspend current of 70 μA. An integrated 3.3 V LDO regulator provides up to 50 mA for external circuitry if required and can also supply the VCCIO pin. The UART interface logic level is configurable through VCCIO, which supports supply voltages from 1.8 V to 5.25 V, allowing direct interfacing with a wide range of logic families without external level shifters.
  • 3. Which physical footprint, terminal count, and mechanical dimensions specify the SSOP-28 package?
    The FT232RL is supplied in a 28-pin Shrink Small Outline Package (SSOP-28). The package body measures 10.20 mm × 5.30 mm (approximately 7.80 mm across the leads), has a maximum height of 2.00 mm, and uses a 0.65 mm lead pitch. The package is Pb-free and RoHS compliant.
  • 4. What does the FT232RL part designation indicate?
    The FT232R designates FTDI's USB-to-UART bridge device family with integrated EEPROM and clock circuitry. The "L" suffix identifies the 28-pin SSOP package, while the related FT232RQ version is supplied in a QFN-32 package. The datasheet does not define the meaning of the "-REEL" suffix or specify reel dimensions or packing quantities.
  • 5. What operating temperature range and solder reflow conditions apply to the FT232RL?
    The FT232RL operates over an industrial ambient temperature range of −40°C to +85°C. It is supplied in a Pb-free, RoHS-compliant package and supports standard lead-free solder reflow with a peak temperature of 260°C. The device is MSL 3 compliant in accordance with IPC/JEDEC J-STD-033A. The datasheet does not specify an ESD rating.
