Unlocking Efficient Data Storage: The Microchip 47L16T-I/SN 16K I2C Serial EEPROM Memory Chip

In the realm of embedded systems and IoT devices, reliable non-volatile memory is crucial for storing configuration data, calibration constants, or operational logs. The Microchip 47L16T-I/SN stands out as a robust 16K I2C serial EEPROM memory chip designed to meet these demands with high efficiency and minimal power consumption. This device integrates seamlessly into systems requiring dependable data retention, offering a blend of performance, durability, and ease of integration.

Housed in a compact SOIC-8 package, the 47L16T-I/SN provides 16 kilobits (2 kilobytes) of electrically erasable programmable read-only memory (EEPROM), organized as 2048 x 8 bits. Its operation via the I2C (Inter-Integrated Circuit) serial interface ensures simple connectivity with microcontrollers and processors, reducing board space and simplifying design complexity. The chip supports a wide voltage range from 1.7V to 5.5V, making it versatile for both low-power battery-operated applications and standard 5V systems.

A key feature of this EEPROM is its low power consumption, critical for energy-sensitive applications. It boasts a standby current of just 1 μA (max) and an active read current of 1 mA (max), extending battery life in portable devices. Additionally, the chip offers high endurance and data retention, capable of supporting over 1 million erase/write cycles per sector and retaining data for more than 200 years. These characteristics ensure long-term reliability in harsh environments or frequent-update scenarios.

The built-in hardware write-protection feature allows users to safeguard memory contents by controlling the WP (Write Protect) pin, preventing accidental data corruption. With an operating temperature range of -40°C to +85°C, the device is suitable for industrial and automotive applications where thermal resilience is paramount. Its page write capability (16 bytes per page) further enhances write efficiency, reducing overall transaction time.

In practice, the 47L16T-I/SN is ideal for smart sensors, medical devices, consumer electronics, and industrial controllers. Its I2C address selection via three configurable pins enables up to eight devices on the same bus, facilitating scalable memory expansion without significant hardware changes.

ICGOOODFIND: The Microchip 47L16T-I/SN combines compact form factor, I2C simplicity, and exceptional reliability, making it a top choice for developers seeking efficient non-volatile memory solutions in space-constrained and power-aware designs.
