REV. 1.0.1
TWO CHANNEL INTEGRATED UART AND RS-232 TRANSCEIVER
NOTE: Pin type: I=Input, O=Output, I/O= Input/output, OD=Output Open Drain. For CMOS/TTL Voltage levels, ’LOW’
indicates a voltage in the range 0V to VIL and ’HIGH" indicates a voltage in the range VIH to VCC. For RS-232
Voltage levels, ’LOW’ is any voltage < 1.5V and ’HIGH’ is any voltage > 3V.
VREFP
40
Pwr +5.0V generated by the charge pump.
VREFN
21
Pwr -5.0V generated by the charge pump.
R_EN
19
I
When the supply voltage is < 3.6V, connect R_EN to VCC.
When the supply voltage is > 3.6V, connect R_EN to GND.
C3
42
I
When the supply voltage is 3.3 V, C3A and C3B should be connected to VCC.
When the supply voltage is 5 V, C3A should be connected to C3B with a 1 uF capacitor to
GND.
RXBSEL
7
I
When RXBSEL is HIGH, RXB is the input to the receiver of the UART.
When RXBSEL is LOW, RXDB is the input to the receiver of the UART.
FAST
15
I
When FAST is HIGH, the maximum serial data rate is 1 Mbps.
When FAST is LOW, the maximum serial data rate is 250 Kbps.
VCC
37, 41
Pwr 3.3V to 5.5V power supply. All CMOS/TTL input pins, except XTAL1, are 5V tolerant.
GND
1, 17, 26
Pwr Power supply common, ground.

PAD
Pwr The center pad on the backside of the 48-QFN package is metallic and is not electrically
connected to anything inside the device. It must be soldered on to the PCB and may be
optionally connected to GND on the PCB. The thermal pad size on the PCB should be the
approximate size of this center pad and should be solder mask defined. The solder mask
opening should be at least 0.0025" inwards from the edge of the PCB thermal pad.
