Additionally, the device is compatible with many different communication protocols, making it a flexible option for use in different communications applications.

Working Principle

The AT28C256-15PC is an electronic non-volatile memory device. It is composed of memory cells attached to addressing and control lines. The addressing lines are used to select memory addresses while the control lines are used to read, write, erase and program the memory cells. The device uses a ten-bit address bus to access the memory cells. This bus is composed of 8 address bits, 1 mode bit and 1 control bit.

The device uses a 16-parameter byte programming algorithm, also known as a page-mode algorithm. With this algorithm, the user is able to program multiple bytes of data at a time by addressing the first byte of data and then sending subsequent bytes of data. This process is known as page programming and can be used to program any number of bytes.

The AT28C256-15PC is also capable of reading data from memory cells. This process is known as read access. Read access can be performed by first addressing the desired data then enabling the read access. Once enabled, the device will read the desired data and output the result on the output bus.

The AT28C256-15PC can also be used to erase data from memory cells. This process, known as ultra-low pulse erasure, is performed by applying a series of pulses to the addressed memory cell. This will reset the data stored in the cell to all zeroes. This process can also be used to erase an entire block of memory cells.

Conclusion

The AT28C256-15PC is a versatile memory module manufactured by ATMEL Corporation. It is a 512Kb BiCMOS auto-programming EEPROM that provides improved features over previous memory products. It has a versatile range of application fields, from embedded systems to medical equipment, and its working principle is based on an advanced 16-parameter byte programming algorithm and read access. This makes the AT28C256-15PC an ideal memory solution for a variety of applications.
