Part 7.2:
EEPROM 24LC04
AX7020 FPGA development board contains an EEPROM, model 24LC04,
and has a capacity of 4Kbit (2*256*8bit). It consists of two 256-byte blocks and
communicates via the IIC bus. The onboard EEPROM is to learn how to
communicate with the IIC bus. The I2C signal of the EEPROM is connected to
the BANK14 IO port on the ZYNQ PL side. Figure 7-5 below shows the design
of the EEPROM
