AT25128T2-10TI Application Field and Working Principle

AT25128T2-10TI is a kind of Serial EEPROM(Electrically Erasable Programmable Read-Only Memory) product and belongs to Memory. This product falls within the family of AT25128 T2-10TI products and combines advanced CMOS technology and extensive memory engineering. It is designed to provide reliable non-volatile storage of information in a small footprint.

Application Field

The AT25128T2-10TI is mainly used for those applications that require a very low-cost solution such as constrained industrial data logging, identification and tracking, medical and health-care, car keyless entries and high-end consumer products. The AT25128T2-10TI provide the following features to suit these needs:

• Compact footprint
• Pin compatible
• Erase/Write cycle endurance
• Data retention for 10 years
• Security write protection
• High-speed data transfers up to 10 Mbps

These features make the AT25128T2-10TI ideal for cost-sensitive and performance-critical applications.

Working Principle

The AT25128T2-10TI is based on the SPI protocol and is compatible with the interface. The Serial Peripheral Interface (SPI) is a synchronous serial data transfer protocol used by microprocessors for communicating with one or more peripheral devices quickly over short distances. The AT25128T2-10TI uses a single-wire serial interface for communication. The data is transferred with a transmission clock which defines the period of data bits transmission.

The AT25128T2-10TI also support advanced programming and erase operations, such as Bulk Erase, Block Erase, Erase All and Byte/Page Erase. Bulk erase operation erases all the bytes in a specified address range in the chip. The Block Erase operation erases a block of 64 bytes of memory at the specified address. The Erase All operation erases all bytes present in the memory chip. Lastly, the Byte/Page Erase operation erases the specified byte or page (256 bytes) at the specified address.

OTP (One Time Programmable) feature is available which can be used as a security feature. AT25128T2-10TI has 256 x 8 bits of non-volatility OTP memory with read, write and erase operation. The memory can be programmed with one-time programmable command that allows the data to be programmed but not erased.

Conclusion

The AT25128T2-10TI is a very cost effective solution for memory applications that require a high speed data transfer rate, low power requirements and robust data retention. The AT25128T2-10TI provides an advanced feature set for security, flexibility, and reliability for applications where high speed, large amounts of memory and low cost are paramount.
