Memory

24LC02BH-E/P is one of the classification of memories with Serial EEPROM, which contains 2K-bit of Electrically Erasable PROM. It is a storage device which couldntains two-wire serial interface. 24LC02BH-E/P support four master devices, including microcontroller, microprocessor, PC and some others with the SPI interface. It is package in 8DIP, 8SOIC and 8TSSOP. It operating at temperature range 2M to 85 ℃ or 2M to 125 ℃ and on-chip self-timed erasing and write cycle with minimal supervision.

Application24LC02BH-E/P are used for applications that require non-volatile memory for the protection of parameter setting and especially suitable for the design of industrial control, instrumentation and other field. 24LC02BH-E/P have many applications, such as programmable logic controllers, energy meters and environmental logger, etc. Besides, 24LC02BH-E/P can be used in data logging or data acquisition to recording the date， such as power off timestamp and program parameters.

Architecture24LC02BC-E/P contains an array of 2024-bit of EEPROM organized as 256-byte. It’s also consists of an 8-bit device address with hardware write protect. 24LC02BC-E/P have serial port stucture including SDA and SCL. The SDA is the data port and SCL is the clock port. It also includes a clock line, which goes from low to high to select device.

Working Principle24LC02BC-E/P communicate with four I/O ports, because it has four different devices address, it helps to locate target devices on the bus. The slave address is set by device address pins (A0, A1, A2). It has two categories of operation: write and read. The write operation is to store data into EEPROM. Firstly, the write operation will be started by sending device address byte and memory address byte. After that, the data byte can be send to the EEPROM. The second operation is “read”, the process is similar to the write process and it can be done after the Master send complete 8 bit address and then the data transmission is starting from the EEPROM.

Conclusion As a summary, 24LC02BH-E/P is a non-volatile EEPROM which implements 24C02BC-E/P on microcontroller. The memory size is 2Kbit and easily operated by microcontroller. The 24LC02BH-E/P are used for the applications require non-volatile memory, such as data logging and memory protection of parameters setting, which are useful for industrial control, instrumentation and many other fields. The 24LC02BH-E/P also consists of two-wire serial interface and two categories of operation: write and read. In the future, it will provide more applications to specific field.
