ADSP-21593BBPZ10

Digital Signal Processor Dsp Overview

The ADSP-21593BBPZ10 is a dual-core SHARC+ digital signal processor from Analog Devices, optimized for high-performance audio and floating-point applications. It features two SHARC+ cores operating at up to 1 GHz each, providing 32-bit, 40-bit, and 64-bit floating-point support alongside 32-bit fixed-point capabilities. Each core includes 5 Mb (640 kB) of L1 SRAM with parity protection. The device integrates 2 MB of on-chip Level 2 SRAM with ECC protection and a 16-bit interface for external DDR3/DDR3L SDRAM. It operates within a voltage range of 950 mV to 1.05 V and supports an industrial temperature range of -40°C to +125°C.

• Professional audio mixing consoles

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade and package variant against the manufacturer's ordering guide, as suffixes denote performance and thermal specifications. Confirm RoHS compliance status and automotive qualification requirements if applicable. Ensure compatibility with existing PCB layouts due to the 400-ball BGA_ED package dimensions.

Digital Signal Processor Dsp Selection Notes

Select this component for designs requiring high-density DSP processing without external memory in many use cases. The ADSP-21593 offers pin compatibility with the ADSP-2156x series, facilitating design scalability. Consider the 16-bit DDR3/DDR3L interface if larger memory capacity is needed beyond the internal 2 MB L2 SRAM.

Digital Signal Processor Dsp Part Context

The ADSP-21593 belongs to the SHARC+ family, which introduces cache enhancements and branch prediction while maintaining instruction set compatibility with previous SHARC products. It is part of a broader portfolio that includes single-core variants and models with integrated Arm Cortex-A5 processors, such as the ADSP-SC592.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21593KBPZ10 serves as a pin-compatible alternative with potentially different speed grades or peripheral configurations. Verify electrical characteristics and software compatibility when substituting.
