SIR Endec for IrDA Applications
Integrated Interface Circuit
Description
The TOIM4232 Endec IC provides proper pulse shap-
ing for the SIR IrDA
as of the 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 stretch-
ing 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 soft-
ware 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).

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