24LC08B-E/SN

The 24LC08B-E/SN is an 8-pin, 1 Kilobit serial Electrically Erasable Programmable Read Only Memory (EEPROM) device typically used in applications where some slight data retention is needed, such as Automotive, Industrial, and Battery-backed applications. The 24LC08B-E/SN is an ideal device for large scale applications, or applications where space or power constraints limit the use of larger memories.

Serial EEPROM memories such as 24LC08B-E/SN are composed of two main components, a non-volatile static RAM and a nonvolatile memory array. The static RAM holds the address and data for the nonvolatile memory array. The static RAM is volatile, meaning that the information stored in it is lost when the power is turned off. The nonvolatile memory array consists of memory cells, word lines, page lines, and address and data I/O buffers.

The 24LC08B-E/SN has 8 pins and is configured like a one-wire serial EEPROM. Data bits in the memory array are encoded by a Look Up Table (LUT) which provides the necessary information for reading and writing data. The LUT uses four data lines for data input, read and write control, address decode, and chip select. The chip can be selected by setting the Chip Select line high, and the Chip Select line can be deselected by bridging the pins together.

The 24LC08B-E/SN includes a variety of functions such as write lock, erase, write, and read. The write/erase functions can be triggered either by the pins of the chip, or by a higher level control. Erasing is achieved by setting the erase line high, while the write line is kept low. Reading is done by keeping the write line low and setting the address lines to the desired memory address. Data is then read from the memory array by clocking out the data at the clock rate.

The 24LC08B-E/SN offers a broad range of applications. It is a suitable choice for applications where long term data retention is required, such as medical records, healthcare applications, automotive, battery-backed systems and more. Its capacity, flexibility and its nominal operating current make it an ideal device for many applications with complex requirements.
