... The typical power consumption is very low with about operational state and in the order of a few microwatts in standby mode. TOIM5232 in the tiny QFN-20 package is the space-minimized version of TOIM5232. ULC Technology: High performance gate array package using multiple metal layer CMOS technology featuring sub-micron channel lengths (0.35 µ ...

... V CC Resets all internal registers. Initially must be high (“1”) to reset internal registers. When high, the TOIM5232 sets the IrDA default bit rate of 9600 bit/s, sets pulse width to 1.627 µs. The V output is simply an inverted reset signal which allows shutdown of a TFDx4x00 CC_SD transceiver when applying the reset signal to the TOIM5232 ...

... RS232 IR-dongle applications. For programming the BR/D pin has to be set active, BR this case the TOIM5232 interprets the 7 LSBs at the TD_232 input as a control word. The operating baud rate will change to its supposedly new baud rate when the BR/D returns back to low (“ ...

... For proper operation, the RS232 must be programmed (using 8 bit, 1 stop, no parity) to send a two character control word, YZ. The control word YZ is composed of two characters, written in hexadecimal, in format: YZ. The transfer rate for programming must be identical with the formerly programmed data rate, or after resetting the TOIM5232, the default rate of 9600 bit/s is used. STEP. ...

... TOIM5232 Vishay Semiconductors TRANSMIT (TXD) CHANNEL Figure 4 shows the transmission in the default mode. For data transfer, the endec is set to that mode by BR/D = “0”. In the examples “6” is always transmitted (binary “00000110”). The “0” is represented in the IrDA protocol by an optical pulse. Also here the LSB is transmitted first after the start bit. “ ...
