FTDI FT232HL Single Channel Hi Speed USB to UART/FIFO IC, 48-Pin LQFP

The FTDI FT232HL-REEL is a versatile, single-channel integrated circuit providing a high-speed bridge between USB and various multipurpose serial or parallel interfaces. It handles the entire USB protocol on-chip, eliminating the need for complex USB-specific firmware programming, which significantly simplifies design and development.

Featuring a Multi-Protocol Synchronous Serial Engine (MPSSE), it effortlessly manages synchronous serial protocols such as USB to JTAG, I²C, SPI (Master), and bit-bang modes. It also supports the proprietary half-duplex FT1248 interface with a configurable data bus width (1, 2, 4, or 8 bits). For asynchronous communication, it offers a full-featured UART interface with hardware handshaking and modem control signals.

Key Performance Features

• High-Speed USB: Fully compatible with USB 2.0 High-Speed (480 Mbps) and Full-Speed (12 Mbps) standards.
• Flexible Data Transfer: Supports UART data rates up to 12 Mbaud, asynchronous 245 FIFO transfers up to 8 MB/s, and synchronous 245 parallel FIFO transfers up to 40 MB/s.
• Simplified Integration: A CPU-style FIFO interface mode streamlines connection to microprocessors. Configurable I/O drive strength (4, 8, 12, or 16 mA) and slew rate allow for optimisation with different loads.
• Broad Compatibility: Works with UHCI, OHCI, and EHCI USB host controllers, ensuring wide system support.

This IC is supplied in a compact 48-pin LQFP package and is designed for robust operation in commercial and industrial environments, with an extended operating temperature range. FTDI’s royalty-free Virtual COM Port (VCP) and Direct (D2XX) drivers are available, removing the requirement for custom USB driver development in most applications.
