behavior of each individual part across industrial temperatures (see 4.5.3 Temperature Coefficients for
the 71M6543H). The resulting tracking of the reference VREF voltage is within ±10 ppm/°C.

Connecting I
2C EEPROMs
I
2C EEPROMs or other I2C compatible devices should be connected to the DIO pins SEGDIO2 and
SEGDIO3, as shown in Figure 33.
Pullup resistors of roughly 10 k
to V3P3D (to ensure operation in BRN mode) should be used for both
SDCK and SDATA signals. The DIO_EEX (I/O RAM 0x2456[7:6]) field must be set to 01 in order to convert
the DIO pins SEGDIO2 and SEGDIO3 to I
2C pins SCL and SDATA.

Connecting Three-Wire EEPROMs
Wire EEPROMs and other compatible devices should be connected to the DIO pins SEGDIO2 and
SEGDIO3, as described in 2.5.11 EEPROM Interface on page 66.
4.8
UART0 (TX/RX)
The UART0 RX pin should be pulled down by a 10 k
resistor and additionally protected by a 100 pF
ceramic capacitor, as shown in Figure 34.

Optical Interface (UART1)
The OPT_TX and OPT_RX pins can be used for a regular serial interface (by connecting a RS_232
transceiver for example), or they can be used to directly operate optical components (for example, an
infrared diode and phototransistor implementing a FLAG interface). Figure 35 shows the basic connections
