AD21584WCBCZ4A10

Overview

The AD21584WCBCZ4A10 is a dual-core digital signal controller (DSC) from Analog Devices, integrating an ARM Cortex-A5 processor and a SHARC+ DSP core. Both cores operate at a maximum clock frequency of 450 MHz. The device features 32 kB L1 instruction cache and 32 kB L1 data cache per core. It operates at a supply voltage of 1.1 V and supports floating-point arithmetic. The component is housed in a CSPBGA-349 package with 80 I/O pins. It meets AEC-Q100 automotive qualification standards and functions within a temperature range of -40°C to +105°C.

Feature Summary

• Dual-core architecture combining ARM Cortex-A5 and SHARC+ DSP
• Maximum operating frequency of 450 MHz for both cores
• AEC-Q100 qualified for automotive applications
• Integrated 32 kB L1 instruction and data caches

Applications

• Automotive infotainment systems
• Advanced driver-assistance systems (ADAS)
• Industrial motor control

Procurement Notes

Verify availability status directly with Analog Devices or authorized distributors, as the part may be subject to limited supply or special order constraints. Confirm the specific suffix '4A10' matches the required pinout and configuration, as ordering suffixes can denote package variations or quality grades. Ensure compliance with RoHS directives and check for any recent PCN notifications regarding manufacturing changes.

Selection Notes

Select this component when high-performance mixed-signal processing is required in automotive environments. The combination of a general-purpose ARM core and a specialized SHARC+ DSP allows for efficient handling of complex algorithms alongside system management tasks. Verify that the 349-ball CSPBGA package fits the PCB layout constraints and that the 1.1 V supply rail is compatible with the system power design.

Part Context

This part belongs to the ADSP-SC58x family of processors, which are designed for demanding embedded applications. The AD21584 variant specifically targets automotive markets due to its AEC-Q100 certification. It shares architectural similarities with other members of the SC58x series but offers specific memory and interface configurations tailored for high-throughput audio and control applications.

Replacement Considerations

Check for direct cross-references within the ADSP-SC58x family, such as the AD21584WJBCZ4A10, if different packaging or temperature ratings are needed. No alternative manufacturers produce functionally identical dual-core ARM/SHARC+ controllers; migration would require significant hardware and software redesign.
