The 93LC66AT-E/ST is an eight-kilobit serial EEPROM that is part of STMicroelectronics’ memory product line. This memory device is designed for a wide range of embedded, data processing, and communication applications, offering high speed and low power consumption among its many features. The 93LC66AT-E/ST also offers various non-volatile data storage options, allowing for reliable storage of application-specific data even during power loss.

The 93LC66AT-E/ST is a Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) device. It has an 8Kb memory array organized as 32 pages of 32 bytes each and features an SPI-compatible Interface. This EEPROM operates with a single +2.7 to 5.5V power supply and has a guaranteed endurance of 100,000 erase/write this makes the 93LC66AT-E/ST ideal for a wide range of applications, including data logging, communication systems, and embedded systems.

The 93LC66AT-E/ST’s Serial Addressable Interface is composed of four pins, namely SI (serial input), SO (serial output), SCK (clock) and CS# (chip select). Serial signals are used for data input and output, allowing for a high speed transfer rate of up to 10 Mbps for data communication. Data is presented byte by byte, and is written and read serially from the memory array.

The 93LC66AT-E/ST’s erase and write cycles are performed in blocks of bytes, which can vary from 1 to 32 bytes. The write cycle is triggered by the CS# pin going low. The CS# pin must remain low until the write cycle is complete, which is indicated by the WEL bit set in the status register. The write cycle can be aborted by releasing the CS# pin prior to this bit being set.

The 93LC66AT-E/ST also includes a number of security features, the most prominent of which is the ability to set up a write protected area (WPA) to prevent any modification of specific parts of the memory array. This can be used to protect application-specific data from unintentional erasure or overwriting. Security is further improved by the ability to protect the content of the entire memory array, allowing for reliable data storage even in the event of power loss.

In addition to its security features, the 93LC66AT-E/ST is a low power device, consuming only 500 µW of maximum power. This makes the device ideal for small, portable devices that must conserve power in order to extend battery life.

The 93LC66AT-E/ST is a low cost, easy to use memory device, designed for a wide range of applications. Its high speed, low power, and array protection features make it a highly reliable data storage option for embedded systems, data processing, and communication applications.
