FT4232H-56Q-REEL

Controllers Overview

The FT4232H-56Q-REEL is a USB interface integrated circuit from the FT4232H series, manufactured by Future Technology Devices International Ltd. It functions as a bridge converting USB 2.0 signals to UART and FIFO interfaces. The device supports high-speed data rates of 480 Mb/s and full-speed operation at 12 Mb/s. It operates within a supply voltage range of 1.62 V to 3.63 V, with a typical operating current of 70 mA. The component is housed in a VQFN-56 package suitable for surface mount technology. It supports an industrial operating temperature range from -40°C to +85°C.

Controllers Feature Summary

• Integrates four configurable serial ports supporting UART, FIFO, JTAG, SPI, and I2C protocols
• Includes two Multi-Protocol Synchronous Serial Engine (MPSSE) channels for bit-bang and synchronous serial modes
• Provides independent baud rate generators for flexible communication timing
• Supports hardware flow control and software handshake options

Controllers Applications

• Computer peripherals requiring USB-to-UART connectivity
• Industrial automation and process control systems
• Audio equipment and sensing instrumentation
• Embedded development using MPSSE for JTAG or SPI programming

Controllers Procurement Notes

Verify the specific reel quantity and packaging configuration against the distributor's listing, as the REEL suffix indicates tape-and-reel delivery. Confirm RoHS compliance status through official manufacturer documentation or certified datasheets prior to procurement. Ensure the ordering suffix matches the required moisture sensitivity level handling procedures for surface-mount assembly processes.

Controllers Selection Notes

Select this component when a single chip solution is needed to provide four independent serial interfaces over a USB connection. The FT4232H-56Q variant offers a compact VQFN-56 footprint compared to larger packages like LQFP-64. Consider the MPSSE capability if simultaneous UART and synchronous serial operations are required. Verify that the 3.3V logic levels align with the target system's voltage requirements.

Controllers Part Context

This part belongs to the FT4232H family, representing FTDI's fifth-generation USB 2.0 high-speed controllers. It succeeds earlier generations by offering higher data throughput and greater interface flexibility. The FT4232H series is widely used in applications replacing legacy RS232/RS422/RS485 connections with modern USB standards while maintaining backward compatibility through virtual COM port drivers.

Controllers Replacement Considerations

FT4232HL-REEL serves as a pin-compatible alternative in a 64-LQFP package. FT4232HQ-REEL is available in a 64-pin QFN package. Verify pinout compatibility and thermal performance differences when substituting between these package variants.
