Memory plays an important role in the reliable operation of the chip. The 93C86C-E/SN is a special kind of memory specifically designed for use in microcontroller applications. It is a Non-Volatile Memory (NVM) chip that uses serial communication to store and read data.

The 93C86C-E/SN is an 8-pin Serial EEPROM chip that offers a wide range of features. It can operate with a single 3.0 to 5.5V supply and supports a fast 2MHz serial interface. It has 256 bits of programmable EEPROM memory and its pin-outs include an input clock (CLK), an output data (DO, or DATA OUT), an input data (DI, or DATA IN), a chip enable (CE, or CS), select (SEL), and two address pins (A0 and A1).

The 93C86C-E/SN is a versatile, low-cost and easy to use chip with many advantages. First, it can operate in both read and write modes and supports advanced programming and protection operations. Second, it uses a single 3.0 to 5.5V power supply and can be configured with an internal on-chip regulator, which eliminates the need for external regulators. Moreover, it consumes less power and has a standby current rating of only 40µA.

The 93C86C-E/SN has multiple applications in the field of microcontrollers. It can be used to store user-programmed microcontroller code in non-volatile memory, so that the program remains intact even if the power is switched off. It can also be used to store confidential data in microcontroller applications and is capable of permanently locking the data in the memory. Other applications include real-time clock applications, low-power analog-to-digital converters, capacitive sensing applications and sensor networks.

The working principle of the 93C86C-E/SN is straightforward. When in write mode, the chip receives data from an outside source via a serial bus and stores it in its internal EEPROM. This can be done by pulsing the chip enable (CE) and chip select (SEL) pins. When in read mode, the 93C86C-E/SN provides data to an outside source by pulsing its CE and SEL pins. The data can be transferred either synchronous or asynchronous depending on the specific application.

In summary, the 93C86C-E/SN is a versatile and reliable non-volatile memory chip that is ideal for use in microcontroller applications. It has 256 bits of programmable EEPROM memory and can operate with a single 3.0 to 5.5 V supply. It is capable of permanently locking data in its memory and has applications in real-time clock applications, low-power analog-to-digital converters, capacitive sensing applications and sensor networks. In terms of its working principle, it can both read and write data via a serial bus by pulsing its chip enable and chip select pins.
