Microchip 25C160T-E/SN: A Robust 16Kb SPI Serial EEPROM for Enhanced Data Storage Applications

In the realm of embedded systems and data storage, reliable non-volatile memory is a cornerstone for preserving critical information. The Microchip 25C160T-E/SN stands out as a high-performance 16-kilobit (2KB) Serial EEPROM component, engineered to meet the rigorous demands of modern data storage applications. Utilizing the widely adopted Serial Peripheral Interface (SPI), this memory IC offers a seamless and efficient method for storing configuration parameters, calibration data, event logs, and other essential system information, ensuring data persistence even when power is removed.

A key advantage of the 25C160T-E/SN is its simple SPI serial interface, which facilitates easy connection to a host microcontroller (MCU) with minimal wiring—typically just four pins for data communication. This significantly reduces board space and simplifies design complexity compared to parallel alternatives. The device supports SPI clock speeds up to 10 MHz, enabling high-speed data transfer for time-sensitive operations. Its 16Kb memory organization is arranged as 2048 x 8 bits, providing ample storage in a compact SOIC-8 package, ideal for space-constrained designs.

Beyond capacity, this EEPROM is built for resilience and endurance. It features a robust endurance rating of 1,000,000 erase/write cycles per sector, alongside a formidable data retention period of over 200 years. These characteristics make it exceptionally suitable for applications involving frequent data updates, such as data logging in industrial sensors, smart meters, or automotive subsystems. The component also integrates advanced write-protection mechanisms, including both hardware and software data protection features, safeguarding stored data from accidental corruption.

Operating across a broad voltage range from 1.8V to 5.5V, the 25C160T-E/SN is versatile for use in various power environments, from battery-powered IoT devices to mains-operated systems. Its extended industrial temperature range (-40°C to +85°C) ensures reliable performance under harsh operating conditions.
