AT24C16D-SSHM-B

Memory IC Overview

The AT24C16D-SSHM-B is a 16-kbit (2 K x 8) serial electrically erasable programmable read-only memory manufactured by Microchip Technology. It features an I²C-compatible two-wire interface with a maximum clock frequency of 1 MHz. The device operates within a supply voltage range of 1.7 V to 3.6 V and supports surface mount installation in an 8-pin SOIC-N package. Key electrical parameters include a 450 ns access time, -40°C to +85°C operating temperature range, and 100-year data retention capability.

Memory IC Feature Summary

• I²C-compatible two-wire serial interface for efficient communication
• Hardware write protection pin for secure data storage
• Self-timed write cycle mechanism with automatic termination
• Schmitt trigger filtered inputs to suppress noise interference

Memory IC Applications

• Industrial control systems requiring non-volatile configuration storage
• Commercial electronic devices needing parameter retention
• Embedded systems utilizing low-voltage power supplies

Memory IC Procurement Notes

Verify the specific suffix 'B' against official Microchip documentation to confirm exact packaging and tape-and-reel specifications. Ensure the 1.7V minimum voltage requirement aligns with your system's power rail capabilities. Confirm the SOIC-N package dimensions match your PCB footprint design constraints before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 1 MHz I²C speed is required alongside a 1.7V to 3.6V operating range. The 16-kbit capacity suits applications storing moderate amounts of calibration data or user settings. Consider the industrial temperature range if the environment exceeds standard commercial limits. Verify that the single-device addressing limitation on the I²C bus fits the system architecture.

Memory IC Part Context

This part belongs to the AT24C16D series of serial EEPROMs from Microchip Technology. It represents a variant optimized for lower voltage operations compared to standard 5V versions. The D-series designation typically indicates specific voltage and performance characteristics distinct from other family members like the AT24C16C.

Memory IC Replacement Considerations

Cross-reference with AT24C16C-SSHM-B for similar functionality but verify voltage range compatibility as the C-series may support up to 5.5V. Check AT24C16D-SSHM-T for reel packaging alternatives if bulk handling is preferred over tube.
