AD21583WCBCZ4A10

Overview

The AD21583WCBCZ4A10 is a digital signal controller from Analog Devices, part of the SHARC+ family. It integrates an ARM Cortex-A5 processor and a SHARC+ DSP core within a single package. The device supports high-performance computing with clock frequencies up to 450 MHz for both cores. It features 32 kB L1 instruction and data caches per core and includes 512 kB of data ROM. The component operates at a supply voltage of 1.1 V and is housed in a CSPBGA-349 package. It offers 80 I/O pins and supports interfaces including CAN, I2C, SPI, UART, and USB. The unit is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Dual-core architecture combining ARM Cortex-A5 and SHARC+ DSP
• Maximum clock frequency of 450 MHz for both processing cores
• Integrated memory comprising 32 kB L1 cache (instruction and data) and 512 kB data ROM
• AEC-Q100 qualification for automotive environment reliability

Applications

• Automotive infotainment systems
• Advanced driver-assistance systems (ADAS)
• Vehicle connectivity modules

Procurement Notes

Verify current availability status directly with Analog Devices or authorized distributors, as supply conditions may vary. Confirm that the specific suffix matches the required pinout and configuration. Ensure handling procedures account for moisture sensitivity levels specified in the datasheet during storage and reflow soldering processes.

Selection Notes

Select this component when a combined control and signal processing capability is required in a compact form factor. The dual-core design allows separation of real-time audio/video processing on the SHARC+ core and system management on the ARM core. Verify interface requirements against the available CAN, SPI, and UART peripherals before finalizing the design.

Part Context

This model belongs to the ADSP-SC58x series of mixed-signal controllers. It shares architectural similarities with other members like the ADSC582, offering comparable core performance but potentially differing in memory size or peripheral configurations. The SHARC+ brand indicates enhanced vector processing capabilities over previous generations.

Replacement Considerations

Check for direct pin-to-pin replacements within the ADSP-SC58x family, such as variants with different memory capacities. Ensure any substitute maintains the same AEC-Q100 grade if automotive qualification is mandatory. Verify software compatibility if migrating between closely related models.
