The AT28HC64B-70SA is a 64K-bit Electrically Erasable Programmable Read Only Memory (EEPROM) manufactured using advanced CMOS technology. It can store up to 64K bytes of data, accessed on a byte basis. This makes it ideal for use in applications that require non-volatile memory.

The AT28HC6B-70SA is a non-volatile, programmable-only memory which requires an external source of electrical power to retain the contents of its memory. It contains a 64K-word array of 8-bit memory cells, each with its own latch. The cells are arranged in 4 x 256-word pages of eight bits each, and single bits can be written. The AT28HC64-70SA can be programmed electrically with a uniquely generated programming code.

The AT28HC64B-70SA is designed for low-power applications. It has an operational voltage range from 3.0V to 5.5V, and a maximum quiescent current of 20µA at 2.5V and 4MHz. This makes it a great choice for applications that require low power consumption.

In terms of application fields, the AT28HC64B-70SA is a great choice for applications that require non-volatile memory and low power consumption. It is ideal for use in industrial, automotive and medical applications, as well as in consumer electronics, communications and data processing applications.

In terms of its working principle, the AT28HC64B-70SA is organized as 4K x 16-bit pages, with 8-bit wide data transfers. The memory is organized into sectors of 4K x 16 words and pages of 256 x 8 words. The data is programmed and erased electrically by writing specific patterns of 0\'s and 1\'s to the memory cells and applying a special “programming voltage”.

Reading and programming of the AT28HC64B-70SA is accomplished through the use of an external high-voltage programming device. Programming voltages are applied to the memory for the specified time intervals, and then the programming voltage is removed. This process is repeated for each consecutive page of the memory.

Reading of AT28HC64B-70SA is accomplished through the use of a serial or parallel port. The data is read out to the connected device, and the memory is reset to its preprogrammed state. Once the data is read out, the user can then erase the contents of the memory and reprogram it.

In conclusion, the AT28HC64B-70SA is an ideal choice for applications that require non-volatile memory and low power consumption. It is organized as 4K x 16-bit pages with 8-bit wide data transfers and is programmed and erased electrically. It is also capable of being read and programmed through the use of an external programming device or a serial or parallel port.
