The A0 and A1 pins are no-connects.The AT24C16A won't use the device address pins, which limitations the amount of products with a solitary bus to 1. The A0, A1 and A2 pins are no-connects.

Create Secure (WP): The AT24C02A/04A/08A/16A possess a Create Guard pin that provides hardware information protection. The Create Guard pin makes it possible for standard read/write oper- ations when related to ground (GND).

Once the Write Secure pin is connected to VCC, the create security characteristic is enabled and operates as proven within the subsequent table. Memory Corporation AT24C02A, 2K SERIAL EEPROM: Internally organized with 32 webpages of eight bytes each and every, the 2K calls for an 8-bit data phrase tackle for random term addressing.

AT24C04A, 4K SERIAL EEPROM: The 4K is internally arranged with 32 internet pages of 16 bytes just about every. Random word addressing needs a 9-bit data phrase address. AT24C08A, 8K SERIAL EEPROM: The 8K is internally organized with sixty four webpages of sixteen bytes each individual.

Random word addressing demands a 10-bit facts phrase deal with. AT24C16A, 16K SERIAL EEPROM: The 16K is internally structured with 128 web pages of 16 bytes each individual. Random word addressing demands an 11-bit data term address. Take note: 1. This parameter is characterised and is not 100% tested.
