24LC16B-I/S15K (hereinafter referred to as 24LC16B) is a 2Kb CMOS Serial Electrically Erasable PROM, in the memory category. It is a 16-bit device which offers high storage capacity, low power operation and a robust write cycle capability. Equipped with a serial SPI or I2C interface, the 24LC16B is ideal for applications that require high data rates, large amounts of data storage, and low-power memory applications. The 24LC16B is a versatile memory solution for many different device applications.

Application Field

24LC16B is commonly used in a variety of applications such as automotive, medical, industrial, consumer, and communications. It is especially suited for devices with limited internal memory capacity and for applications that demand high performance and reliability. Additionally, 24LC16B can be used in devices with limited system resources, making it well-suited for low-end embedded systems. For example, some automotive applications use 24LC16B in airbag monitoring systems, where a large amount of reliable data must be stored and accessed quickly. 24LC16B is also used in many consumer electronics and medical device applications, where a robust and long-lasting memory solution is needed.

Working Principle

The 24LC16B operates on a 2 wire serial interface, either SPI or I2C, which uses a 9-bit data format. The write cycle consists of three steps: first, an address is sent with write enable (WR) signal. Then, suitable page(s) of data can be written, followed by a write disable signal (WR bar). The read cycle consists of two steps: the address is sent and the data is read. The device is organized as a single block of memory divided into 16 pages of 8 bytes each. Each page may be written separately and can be written to independently of the other pages. Data can be written up to the capacity of individual page, with data within one page being consecutively written beyond the capacity of the page.

The 24LC16B employs the I2C protocol, thus it is addressable by a 4-bit address. Data is stored in the device\'s memory array, which is organized as a single block of memory divided into 16 pages of 8 bytes each. With a write enable pin, data can be written to the device in either a byte, page, or full chip mode. With a read enable pin, data can be read from the device in either byte or page mode. The device also features a write-protect pin to enable or disable data writing from the device.

24LC16B is self-timed and offers a maximum write access time of 5ms, which is much faster than other PROMs. It is also very reliable and contains automatic data protection against inadvertent write operations. In addition, it offers a wide temperature range of -20°C to 70°C, making it suitable for a variety of applications.

Conclusion

24LC16B is a versatile and reliable memory solution for many different device applications. It combines high storage capacity with low power consumption and robust write cycle capability. With a 2 wire serial interface, either SPI or I2C, the 24LC16B is attractive for embedded and consumer applications that require reliable and fast data storage. Its fast write access and wide temperature range make 24LC16B the ideal choice for mission-critical applications that demand high performance and reliability.
