Additionally, it is available in a wide temperature range (–40°C to +85°C) and provides a reliable operation of up to 1 million write cycles and up to 100,000 erase cycles.

Applications of 93LC86T/SN

The 93LC86T/SN can be used in a wide variety of applications such as automotive, industrial, medical, instrumentation, telecommunication, and military. Additionally, it is suitable for storing configuration information in microcontrollers, programmable logic controllers (PLCs) and industrial Ethernet devices. Other applications include data logging, adjustable thresholds, and programmable parameters.

Working Principle of 93LC86T/SN

The 93LC86T/SN consists of a two or three wire serial interface. The memory is organized into four separate blocks of 64-bits each. Each block is accessed by sending the 30-bit serial address, followed by the data, which is to be written/read. The device initiates a write/erase operation by sending a write enable/write/erase command. The device is programmed by applying a write pulse, which is between 4 and 10 µs with a voltage of up to 8.0V.

The data is read by sending a read command followed by the address. The device responds with the data stored in the specified address. The device is capable of being written and read at the same time, allowing for the data to be updated without waiting for the write cycle to complete. The 93LC86T/SN also supports a hold feature which allows the device to hold the data state until it is written again, reducing the power usage when the device is not in use.

Conclusion

The 93LC86T/SN is a serial electrically erasable programmable read-only memory (EEPROM) device which is highly applicable in a variety of industries and applications. The device has a two-wire or three-wire serial interface, allowing for easy programming and communication between the system and the device. Additionally, it is capable of up to 100,000 erase cycles, up to 1 million write cycles and low standby current consumption. All these features make the 93LC86T/SN an ideal device for a variety of applications which require reliable and precise data manipulation.
