ADSP-BF516BSWZ-4F4

Digital Signal Processor Dsp Overview

The ADSP-BF516BSWZ-4F4 is a Blackfin embedded processor from Analog Devices, operating at a maximum clock frequency of 400 MHz. It utilizes a Micro Signal Architecture (MSA) featuring two 16-bit MACs, two 40-bit ALUs, and four 8-bit video ALUs. The device includes 116 Kbytes of on-chip memory, comprising L1 instruction and data SRAM/cache and a scratchpad. It is housed in a 176-lead LQFP_EP package with an exposed pad. Operating voltages range from 1.1 V to 1.47 V for the core and support 1.8 V, 2.5 V, or 3.3 V I/O levels. The component supports an industrial temperature range of -40°C to +85°C.

Digital Signal Processor Dsp Feature Summary

• Blackfin MSA Core: Dual 16-bit MACs, dual 40-bit ALUs, and SIMD multimedia capabilities.
• Memory System: 116 Kbytes total on-chip memory with configurable L1 cache/SRAM and MMU.
• Peripheral Interface: Includes 2 SPORTs, 2 UARTs, 2 SPIs, RSI controller, TWI, and 40 GPIOs.
• Package: 176-lead LQFP_EP (with exposed pad) suitable for surface-mount applications.

Digital Signal Processor Dsp Applications

• Industrial motor control and automation systems
• Portable medical devices requiring low power consumption
• Embedded network-connected applications
• Audio processing and telecommunications equipment

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'F4' against the manufacturer's current ordering guide to confirm voltage grades and automotive qualification status. Ensure ESD precautions are taken during handling due to moisture sensitivity classification. Confirm that the 176-lead LQFP_EP footprint matches the target PCB design guidelines provided in the datasheet outline dimensions.

Digital Signal Processor Dsp Selection Notes

Select this model when a 400 MHz performance grade is required within the BF51x family. The 'B' indicates the 176-lead LQFP_EP package option. Compare against the ADSP-BF516BBCZ variant if a BGA package is preferred for higher pin density. Ensure the application does not require the Ethernet MAC found only in the BF518 variants.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-BF512/BF514/BF516/BF518 Blackfin family. It shares architectural compatibility with other members of the series, allowing for code portability. The BF516 sits between the BF514 and BF518 in terms of peripheral availability, specifically lacking the integrated Ethernet MAC present in the BF518 models.

Digital Signal Processor Dsp Replacement Considerations

Direct functional replacements include other speed grades of the ADSP-BF516 series such as the ADSP-BF516BBCZ-3 (300 MHz). Package-compatible alternatives within the same family include the ADSP-BF516KSWZ-4 in the LQFP-176 package, though verification of pinout and electrical characteristics is required.
