FTDI FT4232HL-R Quad USB to UART/MPSSE IC LQFP64

The FTDI FT4232HL-R is a quad high-speed USB 2.0 (480Mb/s) to multipurpose UART/MPSSE interface IC, supplied in a compact 64-pin LQFP package. As a 5th generation USB device, it integrates four UART channels, two of which can be independently configured as MPSSE (Multi-Protocol Synchronous Serial Engine) engines. This flexibility allows the FT4232H to operate as two UART/bit-bang ports plus two MPSSE engines, enabling emulation of JTAG, SPI, I2C, bit-bang, or other synchronous serial protocols.

The entire USB protocol is handled on-chip, so no USB-specific firmware programming is required. The device is compatible with USB 2.0 high-speed (480Mbits/s) and full-speed (12Mbits/s) modes. Features include independent baud rate generators, RS232/RS422/RS485 UART transfer data rates up to 12Mbaud, an adjustable receive buffer timeout, and a 3.3V single supply operating voltage. It supports USB bulk data transfer mode (512-byte packets in high-speed mode) and a UART interface with 7/8-bit data, 1/2 stop bits, and odd/even/mark/space/no parity options. The IC boasts low operating and USB suspend current, with an ambient operating temperature range from -40°C to 85°C, making it suitable for demanding environments.

This component is ideal for applications in communications, networking, consumer electronics, portable devices, and industrial systems. Its robust design and advanced features ensure reliable performance in a variety of embedded and interface bridging applications.
