24AA256T-E/MS

Memory

The 24AA256T-E/MS is a 256-Kilobit serial EEPROM, ranging from 400kHz to 1MHz Clock rates, with a low-voltage, two-wire I2C-compatible serial interface. It is designed to serve a full range of I2C-based applications.

The 24AA256T-E/MS application field is broad, including factory/machine settings, identification, security, and information storage. This EEPROM is also widely used in embedded systems, hand-held communications, computers, automotive electronics, and other industrial applications, and can store information permanently, such as serial numbers, product codes, and installation specifications.

The 24AA256T-E/MS provides several features, including a write-protect feature that prevents accidental erasures and writes, two 8-bit user bytes, and a maximum read and write cycle times of 5ms and 1ms, respectively. The device is offered in 8-pin DIP and SOIC packages, as well as 8-pin MSOP and TSSOP packages.

Working Principle

The 24AA256T-E/MS utilizes an advanced CMOS technology, featuring a small footprint and low power consumption. It is also energy efficient, using less than 0.35mA for write operations, and it has a data retention of up to 40 years. The device also utilizes a temperature range of -55°C to +125°C.

The 24AA256T-E/MS consists of a two-wire serial interface, used for communication with a system controller. The device can operate in Standard Mode (100kHz), High-Speed Mode (400kHz), and Fast-Mode Plus (1MHz). The device has a low-power sleep mode, in which a low current is drawn, and a standby mode that automatically enters a more power optimized mode upon inactivity.

The 24AA256T-E/MS utilizes a 7-bit addressing protocol, which allows for up to 128 device addresses. The device also has an open-drain interrupt pin (I/O1), which is used for signaling events, such as write cycle complete or device failure, to the system controller. This interrupt pin is active low and can be used as a general purpose input or output pin.

The device has the capability to write up to 256 bytesto the device in a single write cycle. The write command consists of a Start Condition followed by the address byte, followed by data bytes, and terminated by a Stop Condition. The write command is acknowledged by the device indicating that the write operation was successfully completed.

The 24AA256T-E/MS is a cost-effective and reliable solution for applications that require high memory density and low power consumption. The device is also highly configurable, making it suitable for a variety of applications. The device is robust, easy to use, and low-maintenance.
