Implementation Characteristics
Please refer to the MicroChip 24AA00 DataSheet for Protocol and Programming specifics.
Pull-Up Resistor
The Circuit board designer is required to place external pull-up resistors (10KΩ recommended) on the
SDA/SMBDATA & SCL/SMBCLK/CFG_SELO lines (per SMBus 1.0 Specification, and EEPROM
manufacturer guidelines) to Vcc in order to assure proper operation.
I2C EEPROM Slave Address
Slave address is 1010000.
Note: 10-bit addressing is NOT supported.
In-Circuit EEPROM Programming
The EEPROM can be programmed via ATE by pulling RESET_N low (which tri-states the Hub’s
EEPROM interface and allows an external source to program the EEPROM).
