Memory plays an integral role in a computer’s operation. Memory, defined as the storage and retrieval of information, is a vital component of any computer system. This article will look at the application field and working principle of AT28C64E-20JC, a 64K-bit CMOS static EEPROM.

AT28C64E-20JC is a 64K-bit CMOS static EEPROM, which stands for Electrically Erasable Programmable Read-Only Memory. It is manufactured by Atmel, and it is one of the most popular EEPROMs available on the market today. The AT28C64E-20JC is used in a wide variety of applications, such as embedded systems, robotics, instrumentation and more. This type of memory is extremely useful for applications that require low power usage and high-density storage.

The AT28C64E-20JC operates as a static EEPROM, meaning that it stores information without a power source and does not require refreshing to maintain the data. This makes the AT28C64E-20JC a reliable and cost-effective memory solution. Furthermore, the AT28C64E-20JC can be programmed and reprogrammed multiple times, giving it an additional advantage over other types of memory.

The working principle of the AT28C64E-20JC is based on the concept of Floating Gate technology. In this technology, an electric field is used to tunnel electrons from the control gate to the floating gate. This transfers charge from the control gate to the floating gate and changes the threshold voltage of the transistor, thus allowing for data to be written to the memory cell.

The AT28C64E-20JC can run on a variety of power supplies, ranging from 2.7V to 5.5V. The device features endurance up to 100,000 write/erase cycles, with a write time of 10ms per byte. It also features a low-power standby mode where power consumption can be reduced to as low as 0.1µA.

The AT28C64E-20JC is an affordable, low power and reliable memory solution. Some of its key advantages include: low voltage operation, high endurance, small size and weight, easy programming, high-density storage and multiple reprogramming capability.

In conclusion, the AT28C64E-20JC is a versatile and efficient memory solution. Its EEPROM technology makes it suitable for a variety of applications, such as embedded systems, robotics, instrumentation and more. Furthermore, the AT28C64E-20JC is robust, reliable and easily reprogrammable. With its low power consumption and high-density storage, the AT28C64E-20JC is the perfect memory solution for any modern device.
