25AA128-I/MF Datasheet/PDFMemory – 25AA128-I/MF Application Field and Working Principle
25AA128-I/MF is a support voltage of 1.65V-5.5V，a 128 Kb serial EEPROM with 128 byte page write mode and a wide range of operating temperature （-40℃ to +85℃）. It has I2C serial interface and single power supply, and has widely-used in many applications fields.
The Application Fields of 25AA128-I/MF
25AA128-I/MF serial EEPROM is widely applied in aerospace, automotive, communication, consumer electronics, entertainment and home automation, industrial, medical and wearables. Also because of the low power consuming, first class reliability, flexibility, wear leveling, leverage and customization and flexibility, it is widely involved in data storage, data security, CPU register, encryption, and digital signature.
How Does 25AA128-I/MF Works?
The 25AA128-I/MF serial EEPROM works with a single power supply of 1.65V-5.5V. It has an I2C 2-wire interface, which can be used to establish communication between master and slave devices. For example, it can be used to connect a microcontroller (the master device) and the 25AA128-I/MF EEPROM (the slave device).
In order to connect and operate the 25AA128-I/MF, certain commands are required. The 25AA128-I/MF uses three basic synchronization commands to establish contact between the master and slave: Start, Stop and Ack (Acknowledgement). The Start and Stop commands are used to inform the slave that a transmission has started and ended respectively. The Ack command is used by the master to inform the slave that it has received a successful transmission and that the slave can send the next segment of data.
The 25AA128-I/MF supports 128 byte page write mode, which allows for easy data management. The user can freely choose a data address from 00h to 7Fh,then write the data in a “page”, which might contain a data set from 0 to 128 bytes.
Overall, 25AA128-I/MF is a highly reliable, low power consuming and flexible memory chip, which can be applied in many different fields. Its convenient interface and customized functions make it a popular choice by many engineers.
