... A0 is not used on the 24C04A and must be connected to either 24C01A or 24C02A devices and up to four 24C04A devices may be connected to the bus. Chip selection is then accomplished through software by setting the bits A0, A1 and A2 of the slave address to the corresponding hard-wired logic levels of the selected 24C01A/02A/04A. ...

... WRITE PROTECTION Programming of the upper half of the memory will not take place if the WP pin of the 24C02A or 24C04A is connected to V (+5.0V). The device will accept slave CC and word addresses but if the memory accessed is write protected by the WP pin, the 24C02A/04A will not generate an acknowledge after the first byte of data has been received, and thus the program cycle will not be started when the STOP condition is asserted ...
