DS3645B+

Overview

The DS3645B+ is a secure microcontroller IC manufactured by Analog Devices Inc./Maxim Integrated. It features an embedded 1K x 8 RAM memory configuration and is designed for security applications. The device is housed in a 49-LFBGA, CSPBGA package with a supplier-specific footprint of 49-CSBGA (7x7). It supports surface mount installation and complies with RoHS3 standards.

Feature Summary

• Integrated secure memory architecture for data protection
• Optimized for dedicated security application environments
• Compact ball grid array packaging for space-constrained designs

Applications

• Secure identification systems
• Access control modules
• Authentication hardware

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm the specific suffix designation matches project requirements. Check current lifecycle status as distribution may be limited. Ensure compatibility with existing board layouts regarding the 49-pin CSPBGA form factor before finalizing orders.

Selection Notes

Select this component when a compact, secure microcontroller with integrated non-volatile or volatile storage is required for authentication tasks. The 49-ball BGA package necessitates appropriate PCB design considerations for thermal management and signal integrity. Evaluate if the 1K memory capacity meets the specific algorithmic storage needs of the target security protocol.

Part Context

This part belongs to the DS36xx series of secure microcontrollers from Maxim Integrated, now part of Analog Devices. These devices are engineered to provide robust hardware-level security features, distinguishing them from standard general-purpose microcontrollers by their focus on protecting sensitive cryptographic keys and user data within embedded systems.
