TOIM3232
Vishay Telefunken
ULC Technology:
High-performance gate array package using dual metal layer CMOS technology,
featuring sub-micron channel length (0.8 mm)
Description
The TOIM3232 IC provides proper pulse shaping for
the front end infrared transceivers of the 3000- and
4000-series (3000- and 4000-series devices are in-
frared transceiver compliant to the IrDA standard
made by Vishay Telefunken), as specified by the IrDA
standard. In the transmit mode, the TOIM3232 short-
ens 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 IrDA bit rate varies between 2.4 kbit/s to
115.2 kbit/s.
The TOIM3232 is using a crystal clock 3.6864 MHz for
its pulse stretching and shortening. 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 commu-
nication 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.
