ACE24C32/64B
Two-wire Serial EEPROM
Acknowledge:
All addresses and data words are serially transmitted to and from the EEPROM in 8-bit words. The
EEPROM sends a zero to acknowledge that it has received each word. The happens during the ninth
clock cycle.
Standby Mode :
The ACE24C32B/ACE24C64B features a low-power standby mode which is enabled: (a) upon power-up
and (b) after the receipt of the stop bit and the completion of any internal operations.
Memory Reset :
After an interruption in protocol power loss or system reset, any two-wire part can be protocol reset by following
these steps:
1. Clock up to 9 cycles.
2. Look for SDA high in each cycle while SCL is high and then.
3. Create a start condition.
