Product Overview: Microchip Technology 93AA66A-I/ST

The 93AA66A-I/ST is a high-performance, 4K-bit serial Electrically Erasable Programmable Read-Only Memory (EEPROM) device from the renowned manufacturer, Microchip Technology. This product is designed for a wide range of applications that require low-power and high-endurance non-volatile memory solutions.

With an organization of 256 x 16-bit (words) or 512 x 8-bit (bytes), the 93AA66A-I/ST offers versatility for storing data that requires byte-level or word-level access. It operates under a standard voltage range of 1.8V to 5.5V, making it suitable for various low-voltage applications while ensuring compatibility with most microcontroller logic levels.

Key Features:

• Memory Size: 4 Kbit (512 x 8 or 256 x 16)
• Interface Type: Serial (I2C, 2-Wire)
• Voltage Range: 1.8V to 5.5V, accommodating a wide range of applications.
• Endurance: 1 Million erase/write cycles, ensuring long-term reliability and data retention.
• Data Retention: 100 years, offering a stable and durable storage solution.
• Temperature Range: Industrial (-40°C to +85°C), suitable for harsh environments.
• Packaging: 8-pin TSSOP, providing a compact footprint for space-constrained designs.
• Self-timed Erase and Write Cycles: Automatic erase-before-write and write-cycle timing eliminates the need for external timing control.
• Write Protection: Software write protection for the entire memory array.

The 93AA66A-I/ST incorporates advanced features such as a hardware write-protect pin to prevent inadvertent writes and a write-enable latch that provides further protection against accidental changes to the memory content. Additionally, its low-power consumption makes it an ideal choice for battery-operated and power-sensitive applications.

Whether used in consumer electronics, automotive systems, industrial control units, or medical devices, the 93AA66A-I/ST from Microchip Technology is a reliable and flexible solution for your non-volatile memory needs.
