I
In order to connect I
microcontroller you must enable SW5.7 and
SW5.8 switches, as shown on Figure 19-1. 4K7
pull-up resistors necessary for I
are already provided on SDA and SCL lines once
switches are turned on. Prior to using EEPROM
in your application, make sure to disconnect
other peripherials, LEDs and additional pull-up
or pull-down resistors from the RC3 and RC4
communication lines that could interfere with
the data signals and cause data corruption.

EEPROM is short for Electrically Erasable
Programmable Read Only Memory. It is
usually a secondary storage memory in devices
containing data that is retained even if the device
looses power supply. EEPROMs come with parallel
or serial interface to the master device. Because
of the ability to alter single bytes of data, EEPROM
devices are used to store personal preference and
configuration data in a wide spectrum of consumer,
automotive, telecommunication, medical, industrial, and
PC applications.

communication interface and has 1024 bytes of available
memory. Board contains socket for serial EEPROMs in DIP8 packaging,
so you can easily exchange it with different memory size EEPROM IC.
EEPROM itself supports single byte or 16-byte (page) write and read operations.
Data rates are dependant of power supply voltage, and go up to 1 MHz with 5V power
supply, and 400 kHz for 3.3V power supply.

systems. I²C uses only two bidirectional open-drain lines, Serial Data Line (SDA) and Serial Clock (SCL), pulled
up with resistors. Data and clock lines are driven with a master device. Up to 112 slave devices can be connected
to the same bus. Each slave must have a unique address.
