The Microchip 93LC86BT-I/OT: A Robust 16K-Bit Serial EEPROM Solution

In the realm of non-volatile memory, serial EEPROMs remain a fundamental component for storing critical configuration, calibration, and data-logging information in a vast array of electronic systems. The Microchip 93LC86BT-I/OT stands out as a reliable and versatile solution, offering 16K bits of electrically erasable memory organized as 1024 x 16. Its serial interface and compact package make it an ideal choice for space-constrained applications requiring dependable data retention.

A key feature of this memory IC is its wide voltage operation range. The 93LC86BT-I/OT supports a spectrum from 2.5V to 5.5V, ensuring compatibility with both 3.3V and 5V systems. This flexibility is further enhanced by its low-power consumption, which is critical for battery-powered and portable devices. The device utilizes a simple and efficient 3-wire serial interface (CS, SK, DI, DO), allowing it to communicate with a host microcontroller using a minimal number of I/O pins, thereby simplifying board layout and reducing system cost.

The 7V specification in its title refers to its high reliability during programming. The integrated write-enable latch and software/data protection mechanisms prevent accidental writes, safeguarding stored data from corruption. Data integrity is further ensured with a built-in self-timed erase/write cycle, which requires no external components. With an endurance of 1,000,000 erase/write cycles and data retention of over 200 years, this EEPROM is built for long-term performance.

Housed in a space-saving SOT-23-6 package, the 93LC86BT-I/OT is perfectly suited for consumer electronics, automotive systems, industrial controls, and telecommunications equipment where board real estate is at a premium.

ICGOODFIND: The Microchip 93LC86BT-I/OT is a highly integrated, robust, and versatile serial EEPROM. Its wide voltage range, minimal pin count, and superior reliability features make it an excellent choice for designers seeking a non-volatile memory solution that balances performance, cost, and size effectively.
