Working Principle of the AT27BV256-15JI

The AT27BV256-15JI is an electrically erasable programmable read-only memory (EEPROM). It is used for storing program code and/or data for a wide variety of applications. The device is manufactured using an advanced 0.13µm process technology, which has enabled its internal memory storage capability to be increased from 64K to 256K. It is organized as single-cycle erasable blocks, each block consisting of 128 bytes.

The AT27BV256-15JI EEPROM is written to and read from using the same pins. When data is written to the device, it is first “burned” into a floating gate transistor in the device which can then be read from the device when needed. The device can be written to and read from with a single instruction. The write process is controlled by a low current write circuit which automatically stops writing when a block of 128 bytes has been written.

The AT27BV256-15JI also offers a high-speed programming cycle of 40µs. This allows the device to be quickly written to and read from allowing for faster programming of its internal memory. The device also includes self-timed erase/write detection to ensure that write operations are completed correctly and without data error.

The AT27BV256-15JI features a low power consumption and low absolute current, making it suitable for use in battery-powered applications. The device is also designed to meet AECQ-100 and HASL standards, making it suitable for use in automotive, industrial and medical applications.

Conclusion

The AT27BV256-15JI EEPROM is an ideal memory device for applications that require a high degree of security, low power consumption and long-term data storage. The device is suitable for use in a wide range of applications from embedded systems and automotive to consumer, industrial, medical and aerospace. It is also designed to meet stringent automotive and industrial standards, making it suitable for use in high-reliability environments. In addition, the device is capable of a high-speed programming cycle and offers self-timed erase/write detection for accurate data storage.
