DS1216F

Overview

The DS1216F is a SmartWatch ROM memory controller manufactured by Analog Devices Inc./Maxim Integrated. It utilizes a serial fixed protocol for information access and features a 32-pin DIP socket package with dimensions of 0.600 inches. The device operates within a temperature range of up to 70 °C and supports data retention for 10 years. Timing accuracy is specified at 1 minute per month at 25 degrees Celsius, utilizing a serial 64-bit protocol.

Feature Summary

• Integrates non-volatile memory control with real-time clock functionality via a dedicated serial interface.
• Provides long-term data retention capabilities suitable for embedded system applications requiring persistent storage.

Applications

• Embedded systems requiring persistent timekeeping and data storage
• Industrial controllers needing reliable non-volatile memory management
• Legacy hardware maintenance involving SmartWatch ROM architectures

Procurement Notes

Verify component authenticity due to discontinued status. Confirm RoHS compliance requirements as the part is noted as non-compliant. Ensure compatibility with existing 32-pin DIP sockets and serial protocol implementations before integration into new designs.

Selection Notes

Select this component only when legacy SmartWatch ROM architecture is required. Verify that the 32-pin DIP form factor fits the target PCB layout. Confirm that the serial 64-bit protocol matches the host microcontroller's communication capabilities.

Part Context

This component belongs to the Maxim Integrated SmartWatch family of memory controllers. These devices combine real-time clock functions with non-volatile memory management in a single integrated circuit package, designed for applications requiring precise timekeeping and data persistence without external battery backup circuits.

Replacement Considerations

DS1216B is listed as a similar replacement option from Analog Devices Inc./Maxim Integrated. Verify pinout and protocol compatibility before substitution.
