DESCRIPTION
The TOIM4232 Endec IC provides proper pulse shaping for
the SIR IrDA
4000-series. For transmitting the TOIM4232 shortens the
RS232 output signal to IrDA compatible electrical pulses to
drive the infrared transmitter. In the receive mode, the
TOIM4232 stretches the received infrared pulses to the
proper bit width depending on the operating bit rate. The IrDA
bit rate varies from 2.4 kbit/s to 115.2 kbit/s.The TOIM4232
is using a crystal clock 3.6864 MHz for its pulse stretching
and shortening. The clock can be generated by the internal
oscillator. An external clock can be used, too. The TOIM4232
is programmable to operate from 1200 bit/s to 115.2 kbit/s by
the communication software through the RS232 port. The
output pulses are software programmable as either 1.627 µs
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.
ULC TECHNOLOGY
High performance gate array package using multiple metal
layer CMOS technology featuring sub-micron channel
lengths (0.35 µm).

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 TOIM4232, the default rate of 9600 bit/s is used. STEP. ...
