24LC64T-E/MS

24LC64T-E/MS Application Field and Working Principle

The 24LC64T-E/MS is an 8-pin, 64 Kbit Electrically Erasable Programmable Read Only Memory (EEPROM) device manufactured by Microchip Technology Inc. It belongs to the large family of Memory devices which includes both volatile and nonvolatile memory technologies.

Types of Memory

Memories fall into two main categories: volatile and non-volatile. Volatile memory is typically used as working memory in computers, and typically means Random Access Memory (RAM). Non-volatile memory is the type used to store semi-permanent data, such as programs and data that needs to be retained even when the power is turned off. This type is typically Flash or ROM.

Characteristics of EEPROM

EEPROM is a general category of non-volatile memory, and stands for Electrically Erasable Programmable Read Only Memory. This category of memory technology is often used to store semi-permanent data, with the benefit that the contents can be modified without physically opening the device. This makes EEPROM ideal for many applications, such as programmable logic controller (PLC) applications and embedded control and communication systems.
