The AT24C16D-SSHM-T: A Robust 16Kb Serial EEPROM Solution from Microchip Technology

In the realm of embedded systems and IoT devices, the reliable storage of configuration data, calibration constants, and operational parameters is paramount. The AT24C16D-SSHM-T from Microchip Technology stands as a quintessential solution, offering designers a dependable and efficient non-volatile memory component. This 16-kilobit (2K x 8) serial EEPROM memory chip provides a critical balance of performance, density, and power efficiency for a vast array of applications.

Operating over a broad voltage range (1.7V to 5.5V), this device is engineered for compatibility and resilience. Its low-power consumption makes it exceptionally suitable for battery-powered portable electronics, from medical devices and sensors to smart wearables and industrial handheld tools. The chip leverages the ubiquitous I2C serial interface, enabling communication with a microcontroller via a simple two-wire bus. This drastically reduces board space and simplifies design complexity compared to parallel memory alternatives.

A key feature of the AT24C16D-SSHM-T is its enhanced 16-byte page write capability, which allows for more efficient data writes than single-byte operations. With a write cycle time of 5ms maximum, it ensures data is committed swiftly. The memory array is organized into 128 blocks of 16 bytes each, providing flexible addressing. Furthermore, the device incorporates critical reliability features, including built-in data protection through hardware write-control and a legacy identification page that contains a factory-programmed, unique serial number for enhanced traceability and security.

Housed in an 8-lead SOIC package, the `-SSHM-T` suffix denotes its suitability for standard surface-mount processes and its industrial temperature range (-40°C to +85°C), ensuring stable operation in demanding environments. Designed for high endurance, it supports 1 million write cycles and boasts a data retention period of 100 years, guaranteeing the long-term integrity of stored information.

ICGOODFIND: The AT24C16D-SSHM-T is a quintessential component for designers seeking a reliable, low-power, and compact non-volatile memory solution. Its robust feature set, centered on the standard I2C interface and exceptional endurance, makes it an ideal choice for ensuring data persistence across consumer, industrial, and automotive applications.
