<p>The AT93C66-10PC-2.7 is part of the AT93C family of non-volatile memory solutions, which include low-power, low-voltage products that offer good reliability and electrical performance.</p><p>The AT93C66-10PC-2.7 is a 1-Wire Parallel EEPROM memory chip that features a 2.7V to 5.5V supply voltage, 100kHz clock frequency, 256 bit memory capacity, and access time of 56 us. The AT93C66-10PC-2.7 is available in a SOIC-8 (150 mil) package and can be used in applications such as industrial, commercial, and automotive equipment.</p><p>AT93C66-10PC-2.7 is widely used in various sectors, particularly in industrial systems and automotive, security, medical and A/V systems where non-volatile storage, secure identification and authentication are needed.</p><p>The AT93C66-10PC-2.7 is an EEPROM chip and therefore, its working principle is based on the principle of storing electrons in an electric field. The memory cells used in EEPROM chips employ a Floating Gate Transistor (FGT) to store electrons. The process of writing to the memory cell is done by sending a positive charge to the floating gate, which creates an electric field that attracts electrons to the floating gate. This process of writing to the memory cell is called “programming”. Similarly, the process of removing electrons from the memory cell is called “erasing”. This process is done by sending a negative voltage to the floating gate.</p><p>The AT93C66-10PC-2.7 features various features like data protection, X8 code ID, and write protection/lock-out bits. The data protection feature will protect the data stored in the memory, while the X8 code ID will provide a unique 8-bit code for each AT93C66 device, which is used for identification by the system. The write protection/lock-out bits provide additional security, as it can be used to prevent unauthorized writing to the memory.</p><p>In summary, the AT93C66-10PC-2.7 is a low power, low voltage, non-volatile memory solution that is used in a variety of applications. It is based on the principle of storing electrons in an electric field, using a Floating Gate Transistor (FGT). The memory chip features various features such as data protection, X8 code ID and write protection/lock-out bits, resulting in good reliability and electrical performance.</p>
