Introduction

The CAT24C256YIGT3JN is a Non-Volatile Memory (NVM) from ON Semiconductor. It is a 256Kbits CMOS Serial EEPROM device which utilizes the industry standard I2C serial two-wire bus for communications.

Features

• Highly integrated: The device requires only a single 5V supply to operate and no external components are required. This simplifies design process and reduces cost.
• Reliable:The device is 100% tested for autobaud, data retention, and other performance specifications.
• Flexible: The device supports multiple memory array configurations, including the popular 256Kbit, 32Kbyte.

Application field

The CAT24C256YIGT3JN is widely used in a wide range of applications, such as for remote sensing, industrial automation, medical equipment, automotive, consumer electronics and home appliances, as well as in avionics and military system operations.

Working principle

The CAT24C256YIGT3JN consists of a 256Kbit NVM array which is divided into 8 blocks. Each block is divided into smaller page size blocks, where a page is a byte-wide area. Each byte can be programmed with data. Data can be written to a page or read from it.

The CAT24C256YIGT3JN writes data using a write cycle. This consists of sending a start condition, followed by a slave address, the write address and data, followed by a stop condition. After the write cycle, the device will enter a standby mode. Data can then be read from the device by sending a start condition, followed by a slave address and the read address, followed by the data and a stop condition.

The device is also able to perform random access of the memory arrays and program data with the use of a random access command. This command consists of sending a start condition, followed by a slave address and the write address and data, followed by a stop condition. After the command, the device will enter a standby mode.

Conclusion

The CAT24C256YIGT3JN is a highly integrated Non-Volatile Memory (NVM) device ideal for a broad range of applications. It features a 256Kbit memory array, which is divided into 8 blocks, and is able to be programmed by sending the appropriate commands. Its flexibility and reliability make it a great choice for many applications.
