The Microchip 24LC16BT/SN: A Robust 16K I²C Serial EEPROM Solution

In the realm of embedded systems and data storage, reliable non-volatile memory is a cornerstone. The Microchip 24LC16BT/SN stands out as a premier solution, offering designers a robust and highly versatile 16Kbit (2K x 8) serial EEPROM memory chip. Its integration of the ubiquitous I²C protocol makes it an indispensable component for a vast array of applications, from consumer electronics to industrial systems.

This memory IC is organized as 256 pages of 8 bytes each, providing a flexible structure for efficient data handling. A key feature of the 24LC16BT/SN is its industry-standard two-wire I²C serial interface, which minimizes board space and simplifies design by requiring only two bus lines for communication: Serial Data (SDA) and Serial Clock (SCL). This allows for significant reductions in component count and interconnect complexity, especially when multiple devices need to share the same bus.

The device supports a wide voltage range from 1.7V to 5.5V, making it perfectly suited for both 5V and modern low-voltage 3.3V systems. This flexibility ensures compatibility across diverse hardware platforms. Furthermore, it is designed for low-power operation, featuring a standby current of just 1 µA (max.), which is critical for battery-powered and energy-sensitive applications.

Built for endurance and data retention, this EEPROM is specified for 1,000,000 erase/write cycles and offers impressive data retention of over 200 years. Its hardware write-protect pin provides an additional layer of security, safeguarding critical memory contents from accidental overwrites or corruption.

The 24LC16BT/SN also incorporates advanced packaging in an 8-lead SOIC (SN), which is ideal for automated assembly processes. Its 8-byte page write buffer enables faster writing operations, while its internally organized blocking scheme allows for up to eight devices (16K each) on the same bus, offering a straightforward path to memory expansion without additional control lines.

ICGOOODFIND: The Microchip 24LC16BT/SN is a quintessential choice for engineers seeking a reliable, low-power, and easily interfaced non-volatile memory. Its combination of a standard I²C interface, wide voltage operation, and exceptional reliability makes it a go-to component for ensuring data persistence in countless electronic designs.
