FT4232HAQ-REEL

Controllers Overview

The FT4232HAQ-REEL is a fifth-generation USB device from FTDI, designed as a USB 2.0 high-speed (480Mb/s) to UART/MPSSE integrated circuit. It features four independent, configurable interfaces, with two channels capable of operating as Multi-Protocol Synchronous Serial Engines (MPSSE). This allows the chip to function as two UART/Bit-Bang ports and two MPSSE engines for protocols like JTAG, SPI, or I2C. The component complies with AEC-Q100 Grade 2 automotive standards, supporting an extended temperature range of -40°C to +105°C. It operates on a core voltage of 1.08V to 1.32V and includes built-in FIFO buffers, programmable baud rates, and hardware flow control.

Controllers Feature Summary

• Automotive-grade reliability compliant with AEC-Q100 Grade 2 standards for harsh environments
• On-chip processing of the entire USB protocol eliminates the need for custom firmware programming
• Dual MPSSE engines enable simultaneous simulation of JTAG, SPI, I2C, and bit-bang modes
• Configurable interface options support RS232, RS422, and RS485 transmission speeds up to 12Mbaud

Controllers Applications

• Automotive infotainment systems and instrument clusters
• Industrial automation and process control equipment
• Medical devices requiring certified interface components
• Computer peripherals and data acquisition systems

Controllers Procurement Notes

Verify that the specific suffix 'AQ' denotes the automotive qualification and QFN-64 package configuration. Confirm the reel packaging type matches production requirements. Ensure the supplier provides traceability documentation consistent with automotive supply chain standards. Check for RoHS compliance status relevant to the manufacturing date code.

Controllers Selection Notes

Select this component when automotive certification (AEC-Q100 Grade 2) is mandatory for the application. It is suitable for designs requiring four serial interfaces with mixed UART and synchronous protocol capabilities. Consider the 1.08V-1.32V core voltage requirement for power budget calculations. Compare against non-automotive variants if environmental ratings do not require Grade 2 specifications.

Controllers Part Context

This part belongs to the FT4232H series, representing FTDI's fifth-generation USB bridge technology. The 'A' suffix typically indicates automotive qualification, while 'Q' specifies the QFN package. The '-REEL' suffix denotes tape-and-reel packaging for automated assembly. It shares architectural similarities with the FT4232HQ but differs in operating temperature and reliability standards.

Controllers Replacement Considerations

FT4232HQ-REEL: Non-automotive grade equivalent with similar electrical characteristics but limited to commercial temperature ranges. FT4232HL-REEL: LQFP package alternative offering pin-compatible mechanical form factor without automotive certification.
