Pin Assignment and Description
Pin
Symbol
Function
I/O
Active
1
RESET
Resets all internal registers. Initially must be HIGH (“1”) to reset internal
registers. When HIGH, the TOIM3232 sets the IrDA default bit rate of
9600, sets pulse width to 1.627
ms. Then the TOIM3232 enters the
front-end (TFDS400) power saving mode by setting VCC_SD low and
therefore switching off the transceiver. When RESET returns to LOW,
the TOIM3232 sets VCC_SD HIGH switching on the front-end device,
and sets the new baud rate in the 1.627
ms pulse width mode. In the
application the RESET pin can be controlled by either the RTS or DTR
line through RS232 level converter. Minimum hold time for reset: 1
ms.
I
HIGH
2
BR/ D
Baud Rate control/ Data.
When BR/ D = 0, RD_232 data is transmitted to the IrDA transmitter pin
TD_IR, while RD_IR is routed to the transmitter pin TD_232. When
BR/ D = 1, data received from the RS232 port is interpreted as the
Control Word. The Control Word programs the baud rate and pulse
width will be effective as soon as BR/ D return to LOW.
I
3
RD_232
Received signal data output of stretched signal to the RS232 port
(using level converter).
O
HIGH
4
TD_232
Input of the signal to be transmitted from the RS232 port (passing the
level converter).
I
HIGH
5
VCC_SD
VCC shutdown output function. This pin can be used to shut down a
transceiver (e.g., TFDx4xxx). Output polarity: Inverted RESET input.
O
LOW
6
X1
Crystal input clock, 3.6864 MHz nominal. Input for external clock *)
I
7
X2
Crystal *)
I
8
GND
Ground in common with the RS232 port and IrDA transceiver ground
9
TD_LED
Transmit LED indicator driver. Use 270
W current limiting resistor in
series to LED to connect to VCC. (VCC = 5 V)
O
LOW
10
RD_LED
Receive LED indicator driver. Use 270
W current limiting resistor in
series to LED to connect to VCC. (VCC = 5 V)
O
LOW
11
NC
No connection
12
S1
User Programmable Bit. Can be used to turn ON/ OFF a front-end
infrared transceiver (e.g., an infrared module at the adapter front)
O
LOW
13
S2
User Programmable Bit. Can be used to turn ON/ OFF a front-end
infrared transceiver (e.g., an infrared module at the adapter back)
O
LOW
14
TD_IR
Data output of shortened signal to the infrared transceiver TFDx4xxx
O
HIGH
15
RD_IR
Data input from the infrared transceiver TFDx4xxx
I
LOW
16
VCC
Supply voltage
I
*)
Crystal should be connected as shown in figure 2. In addition connect a 100 k
W resistor from
Pin 6 to Pin 7 and from Pin 6 and Pin 7 a 22 pF capacitor to ground, respectively. When an
external clock is available connect it to Pin 6 leaving Pin 7 open.
