ULC-Technology:
High-performance gate array package using dual metal layer CMOS technology, featuring
sub-micronic channel length (0.8 m)
Description
The TOIM3xxx series ICs provide proper timing for the
front end infrared transceiver TFDS3000, as specified by
the IrDA standard. In the transmit mode, the TOIM3xxx
provides IrDA-compatible electrical pulses to the in-
frared transceiver TFDS3000 on logic LOW electrical
input. In the receive mode, the TOIM3xxx stretches re-
ceived infrared pulses to the proper bit width at the
operating bit rate. The IrDA bit rate varies from 2.4 to
115.2 kbit/s.
For the UART interface, the TOIM3000 uses the
1.8432 MHz clock input as the fast clock and the baud
clock output from the UART to do the pulse stretching
and shortening. The baud clock is 16 times the baud
rate. The output pulses are fixed at 1.627 s or 3/16 of
bit time.
For the RS232 interface, the TOIM3232 uses an exter-
nal crystal clock 3.6864 MHz for its pulse stretching
and shortening. The TOIM3232 is programmable to
operate from 1200 bit/s to 115.2 kbit/s by the commu-
nication software through the RS232 port. Output
pulses are software-programmable as either 1.627 s
or 3/16 of bit time.
The typical power consumption of both circuits is very
low with about 10 mW in operational state. It is in the or-
der of magnitude of microwatts in standby mode.
