The 93LC86A-E/ST is a serial EEROM (Electrically Erasable ROM) device used in a variety of applications, such as automotive, industrial, medical, and consumer products. It offers a number of features that make it suitable for use in these areas, such as high-speed communication, 2-wire Serial Peripheral Device Interfaces, a wide voltage range, and a low-power consumption design.

The 93LC86A-E/ST uses a single-contact Energy Detect Method for sensing the drive voltage on its EEROM pins. When the voltage falls below a certain threshold, the device functions as an Erasable EEPROM which can be programmed with information. The device can also be used as a Serial EEPROM and is capable of holding up to 16 bytes of data.

The 93LC86A-E/ST requires a clock signal that operates at up to 10 MHz and can work with logic levels between 0 and 5V. The device is available in several different versions with 2K, 4K, 8K, or 16K of nonvolatile memory, and operates over a temperature range of -20°C to +85°C.

The device is capable of communication via the 2-wire, serial peripheral device interfaces. It supports the Serial Peripheral Interface (SPI) and Inter-Integrated Circuit (I2C) protocols, enabling communication over a 3-wire SPI bus or 2-wire I2C bus. The SPI bus operates in both normal and fast modes, allowing for a maximum data rate of 10MHz, while the I2C bus allows for up to 400kHz data transmission.

The 93LC86A-E/ST features a low-current design and requires only 5 to 9mA at 5V for Read and Write operations. Data retention is guaranteed for up to 10 years and blank memory is detected automatically. The device contains an energy detection circuit that allows for low-power programming and reading of the memory.

In addition, it offers advanced security features such as password protection and write protection. The device also includes microcontroller compatible Write Protect and Ready/Busy pins and a latchable chip-select pin. This makes it ideal for adding memory to a system without the need for additional logic.

The 93LC86A-E/ST is a versatile, low-power, high-performance Memory device. It is designed for a wide variety of applications and offers features such as energy detection and advanced security features that make it suitable for use in automotive, industrial, medical, and consumer products.
