AT24C512C1-10CI-2.7 Datasheet


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 4 devices to share a common 2-wire bus. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential. The devices are available in space-saving 8-pin PDIP, 20-pin JEDEC SOIC, 8-pin Leadless Array LAP , and 8-ball dBGA packages. In addition, the entire family is available in 5.0V 4.5V to 5.5V , 2.7V 2.7V to 5.5V and 1.8V 1.8V to 3.6V versions.

*NOTICE:

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Pin Description

SERIAL CLOCK SCL The SCL input is used to positive edge clock data into each EEPROM device and negative edge clock data out of each device.

SERIAL DATA SDA The SDA pin is bidirectional for serial data transfer. This pin is open-drain driven and may be wire-ORed with any number of other open-drain or open collector devices.

DEVICE/PAGE ADDRESSES A1, A0 The A1 and A0 pins are device address inputs that are hardwired or left not connected for hardware compatibility with AT24C128/256. When the pins are hardwired, as many as four 512K devices may be addressed on a single bus system device addressing is discussed in detail under the Device Addressing section . When the pins are not hardwired, the default A1 and A0 are zero.

WRITE PROTECT WP The write protect input, when tied to GND, allows normal write operations. When WP is tied high to VCC, all write operations to the memory are inhibited. If left unconnected, WP is internally pulled down to GND. Switching WP to VCC prior to a write operation creates a software write protect function.

Memory Organization

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.
