ADSP-21368KBPZ-3A

Digital Signal Processor Dsp Overview

The ADSP-21368KBPZ-3A is a member of the Analog Devices SHARC family, utilizing a Single-Instruction, Multiple-Data (SIMD) computational architecture. It operates at a core instruction rate of 400 MHz with an instruction cycle time of up to 2.5 ns. The processor integrates 2 Mbits of on-chip SRAM and 6 Mbits of mask-programmable ROM. It supports IEEE 32-bit single-precision and 40-bit extended-precision floating-point formats alongside 32-bit fixed-point data. The device features two processing elements (PEX and PEY), each containing an ALU, multiplier, and shifter, enabling high-performance digital signal processing optimized for automotive audio applications.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'KBPZ-3A' against the manufacturer's current ordering guide, as the provided datasheet revision history indicates that obsolete models like the ADSP-21368 were deleted from the documentation in March 2019. Confirm package availability and lead times directly with Analog Devices or authorized distributors, as this component may be discontinued or superseded by newer revisions.

Digital Signal Processor Dsp Selection Notes

Select this processor for applications requiring code compatibility with existing SHARC family members (ADSP-2126x, ADSP-2116x, ADSP-2106x). Ensure the design accommodates the 256-ball BGA_ED package if shared memory support between multiple processors is required. Verify power supply requirements of 1.25 V to 1.35 V and thermal management capabilities for the specified operating temperature range.

Digital Signal Processor Dsp Part Context

The ADSP-21368 belongs to the third-generation SHARC processors, which offer higher performance and audiocentric peripherals compared to earlier SISD models. Although the ADSP-21368 model was listed as obsolete in Rev. H of the ADSP-21369 datasheet (March 2019), it shares the same architectural foundation as the ADSP-21369. It utilizes the Super Harvard Architecture to eliminate I/O bottlenecks through multiple internal buses.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21369 is the primary successor in the same datasheet family. Developers should verify source code compatibility and peripheral pinout differences when migrating from the ADSP-21368 to the ADSP-21369.
