Product Summary
The FT232BM is the 2nd generation of FTDI popular USB UART i.c. The device maintains a high degree of pin compatibility with the original, making it easy to upgrade or cost reduce existing designs as well as increasing the potential for using the device in new application areas. The applications of the FT232BM include: (1)USB and RS232 Converters; (2)USB and RS422 / RS485 Converters; (3)Upgrading RS232 Legacy Peripherals to USB; (4)Cellular and Cordless Phone USB data transfer cables and interfaces; (5)Interfacing MCU based designs to USB; (6)USB Audio and Low Bandwidth Video data transfer; (7)PDA ó USB data transfer; (8)USB Smart Card Readers; (9)Set Top Box ( S.T.B. ) PC - USB interface; (10)USB Hardware Modems; (11)USB Wireless Modems; (12)USB Instrumentation; (13)USB Bar Code Readers.
Parametrics
FT232BM absolute maxing ratings: (1)Storage Temperature:–65℃ to + 150℃; (2)Ambient Temperature ( Power Applied ): 0℃ to + 70℃; (3)VCC Supply Voltage: -0.5v to +6.00v; (4)DC Input Voltage - Inputs: -0.5v to VCC + 0.5v; (5)DC Input Voltage - High Impedance Bidirectionals: -0.5v to VCC + 0.5v; (6)DC Output Current – Outputs: 24mA; (7)DC Output Current – Low Impedance Bidirectionals: 24mA; (8)Power Dissipation ( VCC = 5.25v ): 500mW; (9)Electrostatic Discharge Voltage ( I < 1μA ): +/- 2000v; (10)Latch Up Current ( Vi < 0 or Vi > Vcc ): 100mA.
Features
FT232BM features: (1)384 Byte Receive Buffer / 128 Byte Transmit Buffer for high data throughput; (2)Adjustable RX buffer timeout; (3)Full hardware assisted hardware or X-On / X-Off handshaking; (4)In-built support for event characters and line break condition; (5)Auto Transmit Buffer control for RS485; (6)Support for USB Suspend / Resume through SLEEP# and RI# pins; (7)Support for high power USB Bus powered devices through PWREN# pin; (8)Integrated level converter on UART and control signals for interfacing to 5v and 3.3v logic; (9)Integrated 3.3v regulator for USB IO; (10)Integrated Power-On-Reset circuit; (11)Integrated 6MHz-48MHz clock multiplier PLL.
