... Description The AT24C512 provides 524,288 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 65,536 words of 8 bits each. The device’s cascadable feature allows up to four devices to share a common two-wire bus. The device is optimized for use in many industrial and commercial applications where low- power and low-voltage operation are essential ...

... If the pin is left floating, the WP pin will be internally pulled down to GND if the capacitive coupling to the circuit board V >3 pF, Atmel recommends connecting the pin to GND. Switching write operation creates a software write protect function. AT24C512, 512K SERIAL EEPROM: The 512K is internally organized as 512 pages of 128-bytes each. Random word addressing requires a 16-bit data word address. plane is < ...

MEMORY RESET: After an interruption in protocol, power loss or system reset, any two- wire part can be reset by following these steps: (a) Clock cycles, (b) look for SDA high in each cycle while SCL is high and then (c) create a start condition as SDA is high. 1116O– ...

DATA SECURITY: The AT24C512 has a hardware data protection scheme that allows the user to Write Protect the whole memory when the WP pin BYTE WRITE: A write operation requires two 8-bit data word addresses following the device address word and acknowledgment. Upon receipt of this address, the EEPROM will again respond with a “ ...
