ADSP-BF518BSWZ-4

Digital Signal Processor Dsp Overview

The ADSP-BF518BSWZ-4 is a Blackfin embedded processor from Analog Devices, operating at up to 400 MHz. It features a dual-MAC signal processing engine with two 16-bit multipliers, two 40-bit ALUs, and four video ALUs. The device integrates 116 Kbytes of on-chip memory, including configurable L1 instruction and data SRAM/cache, and a 4K byte scratchpad. Key peripherals include an IEEE 802.3 10/100 Ethernet MAC with IEEE 1588 support, two SPORTs, two SPIs, two UARTs, an RSI controller, and a TWI interface. It utilizes a 176-lead LQFP_EP package and supports core voltages between 1.14 V and 1.47 V.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'BSWZ-4' against the manufacturer's current ordering guide to confirm package type, speed grade, and temperature range. Confirm RoHS compliance status through official documentation. Ensure availability aligns with current production lifecycle status as specifications are subject to change without notice.

Digital Signal Processor Dsp Selection Notes

Select this component when an integrated solution combining high-performance DSP capabilities with Ethernet connectivity is required. The ADSP-BF518 offers code compatibility with other Blackfin processors, facilitating migration. Consider the 176-lead LQFP_EP package constraints and the 1.14 V to 1.47 V core voltage requirements during system design.

Digital Signal Processor Dsp Part Context

This part belongs to the ADSP-BF51x family, which includes the BF512, BF514, BF516, and BF518 variants. The BF518 distinguishes itself by including an Ethernet MAC and IEEE 1588 support, whereas lower-tier models lack these network interfaces. All members share the same core architecture and peripheral set except for the Ethernet module.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the Blackfin family include the ADSP-BF516BSWZ-4, though it lacks the integrated Ethernet MAC. For projects requiring identical functionality, ensure the substitute maintains the 400 MHz speed grade and LQFP_EP packaging. Cross-family migration requires significant software adaptation due to architectural differences.
