DS1213B

Overview

The DS1213B is a Smartsocket SRAM memory controller manufactured by Analog Devices Inc./Maxim Integrated. It integrates nonvolatile SRAM management within a 28-pin dual in-line package (PDIP). The device operates on a supply voltage ranging from 4.75V to 5.5V and supports an operating temperature range of 0°C to 70°C. Designed for through-hole installation, it functions as a specialized integrated circuit for maintaining data integrity in smart socket applications.

Feature Summary

• Integrates memory control logic specifically designed for Smartsocket SRAM architectures
• Provides nonvolatile data retention capabilities through integrated controller functionality
• Supports standard industrial temperature ranges for reliable operation

Applications

• Smartsocket SRAM systems requiring integrated memory management
• Industrial embedded systems needing nonvolatile data storage control
• Legacy hardware designs utilizing 28-pin DIP form factors

Procurement Notes

Verify component authenticity due to discontinued status. Confirm package integrity and pin alignment against the 28-PDIP specification. Ensure supply voltage requirements match the 4.75V to 5.5V operational range. Check for manufacturing date codes relevant to legacy system compatibility. Validate RoHS compliance documentation if required for specific regulatory environments.

Selection Notes

Select this component only when a dedicated Smartsocket SRAM controller is required. The 28-PDIP package dictates board layout constraints compared to surface-mount alternatives. Verify that the application environment remains within the specified 0°C to 70°C temperature limits. Consider availability challenges associated with discontinued product lines during design finalization.
