... DLP-USB232M-G USB – SERIAL UART Interface Module The DLP-USB232M-G lead free module uses FTDI’s 2nd generation FT232BM USB-UART chip that adds extra functionality to its predecessor (the FT8U232AM) and reduces external component count. HARDWARE FEATURES • Single Chip USB Asynchronous Serial Data Transfer • ...

... High ). In this mode, any residual voltage on external circuitry is bled to GND when power is removed thus ensuring that external circuitry controlled by PWREN# resets reliably when power is restored. Copyright © DLP Design 2002 DLP-USB232M User’s Manual • Lower Suspend Current Integration of RCCLK within the device and internal design improvements reduce the suspend current of the FT232BM to under 200uA ( excluding the 1 ...

... Table 1 - DLP-USB232M PINOUT DESCRIPTION Pin# Description 1 BOARD ID (Out) Identifies the board as either a DLP-USB245M or DLP-USB232M. High for DLP- USB232M and low for DLP-USB245M. 2 Ground 3 RESET# (In) Can be used by an external device to reset the FT245BM. If not required, this pin must be tied to VCC. 4 RESETO# (Out) Output of the internal Reset Generator. Stays high impedance for ~ 2ms after VCC > ...

... A Self Powered Device can take as much current as it likes during normal operation and USB suspend as it has its own Power Supply Self Powered Device can be used with any USB Host and both Bus and Self Powered USB Hubs. Copyright © DLP Design 2002 DLP-USB232M User’s Manual Figure 1 illustrates a typical USB bus powered configuration. A USB Bus Powered device gets its power from the USB bus. Basic rules for USB Bus power devices are as follows – ...

... Figure 3 shows how to configure the DLP-USB232M to interface with a 3.3v logic device in Bus-Powered configuration. In this example, a LDO regulator provides 3.3 volts from the USB Bus to the target microcontroller and the VCCIO line (pin 10) which in turn will cause the UART interface IO pins to drive out at 3.3v level. ...
