AT28C17E-20PC

AT28C17E-20PC is an Electrically Erasable Programmable Read Only Memory (EEPROM). It is a device which can store electronic data without the need for power. It is used to store data in such a way that it can be quickly retrieved, modified and re-stored. EEPROMs are also referred to as \'non-volatile memory\' because the data stored in them is not lost when the power is turned off.

The AT28C17E-20PC is a 256Kbit EEPROM that comes in SOIC and TSSOP packages. It is designed to be used in applications where the data needs to be stored semi-permanently. It has improved endurance and retention characteristics which make it suitable for long-term data storage applications. It also has an advantage of being accessed much faster than other EEPROM devices.

The AT28C17E-20PC can be used in a wide range of applications. It is commonly used in medical, industrial and automotive applications. Some of the common applications of this EEPROM are engine control units, in-circuit programming, memory back-up, embedded control systems, etc. One of the main advantages of using this EEPROM is that it is pin compatible with popular 8-bit microcontrollers, making it very easy to interface with them.

The working principle of the AT28C17E-20PC is based on the same principles of other EEPROMs. Data is stored in the memory in the form of electrical charges. These electrical charges are then passed through a transistor and stored as data bits. The amount of charge stored on the transistor depends on the amount of current flowing through it. This current is determined by the programming voltage provided to the EEPROM.

When the memory needs to be read, the electrical charges stored on the transistors are measured, and the data is interpreted accordingly. Once the data has been read, it can be modified or written back to the memory. This process is repeated for all the data stored in the memory. The use of decoders in the AT28C17E-20PC allows for the reduction of power consumption and increases the storage capacity and speed.

The AT28C17E-20PC offers many advantages over other EEPROM devices. It is a cost-effective solution for applications where long-term data storage is required. It is easy to program, fast to access and has an improved endurance and retention characteristics. All these features make this EEPROM a great choice and an ideal solution for many applications.
