Default I2C Device Address for Scratchpad and PLL EEPROM Blocks

Version 1
    Question: What are the default I2C device addresses for the CY27EE16 scratchpad memory blocks and PLL configuration block?

     

    Answer:

    The default I2C addresses are as follows:

    Scratchpad EE block 1: 1000000
    Scratchpad EE block 2: 1000001
    Scratchpad EE block 3: 1000010
    Scratchpad EE block 4: 1000011
    Scratchpad EE block 5: 1000100
    Scratchpad EE block 6: 1000101
    Scratchpad EE block 7: 1000110
    Scratchpad EE block 8: 1000111

    PLL configuration EE block: 1101000
    PLL configuration SRAM block: 1101001

    CyberClocks ISR software will enable the user to change the 4 MSB's of the Scratchpad EE block device address, the 4 MSB's will be the same for all 8 blocks and the 3 LSB's count up from 000 to 111.

    The 6 MSB's of the PLL configuration blocks can be modified to the users desired value and will be the same for the EE block and SRAM block. The LSB of the PLL configuration blocks differentiate the EE and SRAM block.
