... SCL clock input signal. Make sure the rising time and falling time conform to the specifications. 4. TEST/WP Pin The S-24C01A does not have a write protection (WP) function. The pin serves as a TEST pin and shoud always be connect to the GND. In the S-24C02A and S-24C04A, this pin is used for write protection. When there is no need for write protection, connect the pin to the GND ...

... When the comparison results match, the slave device outputs the acknowledgment signal during the 9th clock cycle . S-24C01A S-24C02A S-24C04A In the S-24C04A, "A0" does not exist in the slave addresses. So, "A0" becomes "P0." "P0" page address bit and is equivalent to an additional uppermost bit of the word address. Accordingly, when P0=" ...

... CMOS 2-WIRED SERIAL EEPROM S-24C01A/02A/04A 8. Address Increment Timing The address increment timing is as follows. See Figures 15 and 16. During reading operation, the memory address counter is automatically incremented at the falling edge of the SCL clock (the 8th read data is output). During writing operation, the memory address counter is also automatically incremented at the falling edge of the SCL clock when the 8th bit write data is fetched ...
