DS3660B+ is listed in the Application Specific Microcontrollers range at ChipApex. The manufacturer field lists Analog Devices Inc./Maxim Integrated. Its product description is 1KB SECURE MEMORY WITH PROGRAMMA. Review the specifications below when checking this part for your BOM.
The DS3660B+ is a secure microcontroller IC manufactured by Analog Devices Inc./Maxim Integrated. It features 1K x 8 RAM and is housed in a 49-LFBGA, CSPBGA package with dimensions of 7x7 mm (49-CSBGA). The device is designed for security applications and supports surface mount installation. It complies with RoHS3 specifications and carries an ECCN classification of EAR99.
The DigiKey part number 505-DS3660B+-ND indicates that the DS3660B+ is discontinued and no longer provided by this distributor. Current stock levels are zero, and orders for out-of-stock items cannot be accepted due to temporary supply constraints. Delivery timelines are currently uncertain. Alternative packaging options such as tape and reel (DS3660B+TRL) may exist but require verification through official channels.
Engineers selecting this component must account for its discontinued status. Verification of availability through direct manufacturer channels or authorized distributors is essential before design finalization. The 49-pin CSBGA package requires appropriate PCB layout considerations for surface mount assembly. Ensure that the 1K x 8 RAM configuration meets the specific memory requirements of the target security application.
The DS3660B+ belongs to the DS3660 family of secure microcontrollers from Maxim Integrated, now part of Analog Devices Inc. This series is characterized by integrated security features and non-volatile memory solutions. The '+' suffix typically denotes compliance with specific environmental standards, such as RoHS, within the product line.
Publicly confirmed substitute part numbers are not available in the provided data. Due to the discontinued status, alternative components should be evaluated based on pin compatibility, memory size, and security feature sets.
