ADSP-BF516BSWZ-4

Digital Signal Processor Dsp Overview

The ADSP-BF516BSWZ-4 is a Blackfin embedded processor from Analog Devices, operating at a maximum clock frequency of 400 MHz. It utilizes a modified Harvard architecture with on-chip L1 instruction and data memory totaling 116 Kbytes, including configurable SRAM and cache blocks. The core features two 16-bit MACs, two 40-bit ALUs, and four video ALUs. It supports a wide range of operating voltages and includes an external memory controller for SDRAM and asynchronous memories. The device is housed in a 176-lead LQFP_EP package.

Digital Signal Processor Dsp Feature Summary

• Blackfin Processor Core: Dual 16-bit MACs, dual 40-bit ALUs, four 8-bit video ALUs, and a 40-bit shifter.
• Memory Architecture: 116 Kbytes total on-chip memory (L1 Instruction/Data SRAM/Cache + Scratchpad) with MMU support.
• Peripherals: Includes PPI, two SPORTs, two SPIs, two UARTs, RSI controller, TWI, eight 32-bit timers, and 40 GPIOs.
• Package: 176-lead LQFP_EP with exposed pad.

Digital Signal Processor Dsp Applications

• Embedded network-connected applications requiring RISC-like programmability.
• Multimedia processing and signal processing tasks utilizing SIMD capabilities.
• Industrial control systems using the integrated peripherals like PWM and timers.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'BSWZ-4' against the manufacturer's ordering guide to confirm package type (LQFP_EP), temperature range, and speed grade. Ensure compatibility with development tools such as the CrossCore Embedded Studio IDE. Check for RoHS compliance status in the latest datasheet revision.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring up to 400 MHz performance with moderate on-chip memory. Compare with ADSP-BF512 or BF514 if lower memory or peripheral counts are acceptable. Consider the ADSP-BF518 if IEEE 802.3 Ethernet MAC functionality is required, as it is not present in the BF516.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-BF51x family of Blackfin processors, which share code compatibility. The BF516 sits between the BF514 and BF518 in terms of feature set, specifically lacking the integrated Ethernet MAC found in the BF518 but offering the same core performance and general peripheral suite.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-compatible replacements within the same package include other members of the ADSP-BF51x series such as the ADSP-BF514BSWZ-4 or ADSP-BF518BSWZ-4, provided peripheral requirements match. Verify memory configuration differences when substituting.
