Overview
The FT232BM-TRAY is a second-generation USB to asynchronous serial data interface integrated circuit manufactured by Future Technology Devices International Ltd. It operates on a single 4.35V to 5.25V supply and supports USB 1.1 and USB 2.0 specifications with full-speed connectivity at 12 Mbps. The device integrates a 6MHz to 48MHz clock multiplier PLL, an internal 3.3V regulator, and power-on-reset circuits. It features a 384-byte receive buffer and a 128-byte transmit buffer to ensure high data throughput. The component supports UART interfaces with configurable data bits, stop bits, and parity options, accommodating baud rates from 300 to 3M Baud for TTL levels.
Feature Summary
- Integrates level converters for interfacing with both 5V and 3.3V logic systems without external components.
- Supports adjustable RX buffer timeout and auto transmit buffer control specifically for RS485 applications.
- Includes built-in support for event characters and line break conditions within the hardware protocol handling.
Applications
- Converting legacy RS232, RS422, or RS485 devices to USB interfaces.
- Connecting microcontrollers and programmable logic devices (PLDs) via USB.
- Implementing industrial automation controls and PLC communication links.
Procurement Notes
Verify the specific suffix against official FTDI documentation to confirm package type and tape/reel specifications. Ensure the ordering code matches the required quantity format and lead time constraints. Confirm RoHS compliance status through the manufacturer's current datasheet rather than relying solely on distributor listings.
Selection Notes
Select this component when pin compatibility with the original FT8U232AM is required for existing designs. Choose this IC for applications needing integrated level shifting between 5V and 3.3V domains. Consider this part for designs requiring reduced external component count while maintaining high data throughput capabilities.
Part Context
The FT232BM represents the second generation of FTDI’s popular USB UART interface family. It was designed to add extra functionality compared to its predecessor, the FT8U232AM, while significantly reducing the external component count. The device maintains a high degree of pin compatibility with earlier models, facilitating easier upgrades or cost reductions in existing hardware architectures.
