DESCRIPTION
In the transmit mode, the TOIM3232 shortens the RS232 output signal to IrDA compatible electrical pulses to drive the infrared. In the receive mode, the TOIM3232 stretches the received infrared pulses to the proper bit width at the operating bit rate. The clock can be generated by the internal oscillator or an external clock can be used, too. The TOIM3232 is programmable to operate from 1200 bit/s to 115.2kbit/s by the communication software through the RS232 port. The output pulses are software programmable as either 1.627 ms or 3/16 of bit time. The typical power consumption is very low with about 10 mW in operational state and in the order of a few microwatts in standby mode. FEATURES
