Microchip 16 kB EEPROM Serial-SPI 8-Pin SOIC Memory Chip AT25160B-SSHL-B

Microchip AT25160B-SSHL-B is a 16 kB electrically erasable and programmable read-only memory (EEPROM) chip designed for industrial and commercial applications requiring reliable non-volatile memory storage with low power consumption. This memory chip is organized as 2,048 words of 8 bits each and utilizes a Serial Peripheral Interface (SPI) compatible SPI modes 0 and 3 operation. It offers a fast maximum random access time of 80 ns, making it suitable for high-speed data access in embedded systems.

The device operates over a wide voltage range of 1.8 V to 5.5 V, allowing flexible use in low-voltage environments. Its compact 8-pin SOIC surface mount package with a height of only 1.5 mm makes it ideal for space-constrained circuit designs.

The EEPROM features block write protection mechanisms, including a write-protect (WP) pin and software-based write disable instructions to safeguard data integrity. It supports a 32-byte page mode for efficient data writing. Data retention is rated at 100 years, ensuring durability for critical applications.

The operating temperature range from -40°C to 85°C ensures reliable performance in harsh industrial conditions. The supply current is optimized at 10 mA, and write cycles are self-timed within a maximum duration of 5 ms.
