FT4232HL-REEL

Controllers Overview

The FT4232HL-REEL is a USBmadeEZ-FIFO series bridge controller from FTDI, converting USB 2.0 High Speed (480 Mb/s) to four independent serial interfaces in a 64-LQFP package. It supports UART, JTAG, SPI, I2C, and bit-bang modes. Operating voltage ranges from 1.62 V to 1.98 V with a supply current of 70 mA. The device functions within an industrial temperature range of -40°C to 85°C.

Controllers Feature Summary

• Supports four configurable interface channels for versatile protocol integration
• Includes dual Multi-Protocol Synchronous Serial Engine (MPSSE) capabilities
• Features integrated ESD protection mechanisms
• Provides full hardware support for USB protocol handling without firmware programming

Controllers Applications

• USB to Quad UART bridge implementations
• JTAG and SPI programming adapter designs
• Industrial data acquisition systems requiring multiple serial ports
• Embedded system debugging and configuration interfaces

Controllers Procurement Notes

Verify the specific suffix 'REEL' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to assembly. Ensure compatibility with standard surface-mount reflow profiles for LQFP-64 packages during manufacturing planning.

Controllers Selection Notes

Select this component when four independent serial interfaces are required from a single USB connection. Consider the 64-LQFP footprint constraints and 1.98 V maximum operating voltage limits. Verify that the MPSSE functionality meets synchronization requirements for target protocols like SPI or I2C.

Controllers Part Context

This part belongs to the FT4232H family, representing FTDI's fifth-generation USB-to-UART/FIFO ICs. It serves as a high-speed alternative to legacy USB-to-serial solutions, offering enhanced throughput and multi-protocol support within a compact form factor suitable for dense PCB layouts.
