OPERATION DESCRIPTION
The block diagram shows a typical example of an RS232
port interface. The TOIM5232 connects to an RS232 level
converter on one side, and an infrared transceiver on the
other. The internal TOIM5232 baud rate generator can be
software controlled.
When BR/D = 0, the TOIM5232 interprets the channels
TD_232 to TD_IR and RD_IR to RD_232 as data channels.
On the other hand, whenever BR/D = 1, the TOIM5232
interprets TD_232 as control word for setting the baud rate.
The baud rate can be programmed to operate from 1200
bit/s to 115.2 kbit/s. As RS232 level converter, EIA232 or
MAX232 or equivalent are recommended.
When using the TOIM5232 directly connected to an UART it
is compatible to 5 V TTL and 3.3 V CMOS logic.
Typical external resistors and capacitors are needed as
shown in the TFDU4...,TFBS4...-series references.
The output pulse duration can also be programmed, see
chapter “operation description”. It is strongly recommended
using 1.627 μs output pulses to save battery power. As
frequency determining component a Vishay XT49M crystal
is recommended, when no external clock is available.
We strongly recommend not to use this 3/16 mode
because 3/16 pulse length at lower bit rates consumes
more power than the shorter pulse. At a data rate of
9600 bit/s, the ratio of power consumption of both
modes is a factor of 12 (!)
PROGRAMMING THE TOIM5232
For correct data rate dependent timing the TOIM5232 is
using a built-in baud rate generator. This is used when no
external clock is not available as in RS232 IR-dongle
applications. For programming the BR/D pin has to be set
active, BR/D = 1.
In this case the TOIM5232 interprets the 7 LSBs at the
TD_232 input as a control word. The operating baud rate will
change to its supposedly new baud rate when the BR/D
returns back to low (“0”) set the UART to 8 bit, no parity,
1 stop bit.
