AT24C512C-XHD-B Description

The AT24C512C 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 cascading feature allows up to eight 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. The devices are available in space-saving 8-lead SOIC, 8-lead SOIJ, 8-lead TSSOP, 8-pad UDFN, 8-ball WLCSP and 8-ball VFBGA packages. All packages operate from 1.7V to 3.6V or 2.5V to 5.5V. The AT24C512C operates as a slave device and utilizes a simple I²C-compatible two-wire digital serial interface to communicate with a host controller, commonly referred to as the bus master.

This article provides you with a basic overview of the AT24C512C-XHD-B I²C Serial EEPROM, including its pin descriptions, features and specifications, etc., to help you quickly understand what AT24C512C-XHD-B is.

Frequently Asked Questions

How many pins of AT24C512C-XHD-B?
8 Pins.
What’s the operating temperature of AT24C512C-XHD-B?
-40°C~85°C TA.
How does AT24C512 clear all the contents stored inside it?
Write the data directly to overwrite the original one.
What is the essential property of the AT24C512C?
The AT24C512C provides 524,288 bits of Serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) organized as 65,536 words of 8 bits each.
I²C reads AT24C512 and reads FF. What is the reason?
All FF means that the slave does not respond. Because the address line and data line of the I²C bus are both have, it should be high when there is no data. It can be seen that all data received by the host is FF because the slave does not respond. In other words, there are two possibilities, one is that the slave device is faulty; the other is that the address of the slave device sent by the host is incorrect and the slave device does not respond.
Can AT24C512 store uboot instead of flash?
You can only access NandFlash through the NandFlash controller, that is, as long as you know the register address of the Nand controller. NandFlash is not a RamLike device. Put Uboot into nand and store it at address 0 of nand. Pay attention to page alignment when transplanting, so that Uboot can be guided by StepingStone.
