ADSP-BF514KSWZ-3

Digital Signal Processor Dsp Overview

The ADSP-BF514KSWZ-3 is a Blackfin embedded processor from Analog Devices, operating at a maximum clock frequency of 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 includes 116 Kbytes of on-chip memory, comprising L1 instruction and data SRAM/cache and a scratchpad. It integrates peripherals such as two SPORTs, two SPIs, two UARTs, an RSI controller, TWI, and 40 GPIOs. The processor supports flexible booting options and dynamic power management, housed in a 176-lead LQFP_EP package.

Digital Signal Processor Dsp Feature Summary

• Blackfin core with up to 400 MHz performance, featuring two 16-bit MACs and SIMD multimedia capabilities.
• 116 Kbytes of configurable on-chip L1 memory (SRAM/Cache) and external memory controller for SDRAM/asynchronous memories.
• Rich peripheral set including dual SPORTs, dual SPI, dual UART, RSI, TWI, and 40 GPIOs.
• Dynamic power management allowing voltage and frequency scaling for low-power operation.

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 leveraging the rich peripheral interface and real-time clock.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade and package variant against the ordering guide in the Rev D datasheet. Confirm that the KSWZ suffix corresponds to the 176-lead LQFP_EP package with exposed pad. Ensure compatibility with the required operating voltage range and temperature specifications defined in the electrical characteristics section.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high-performance DSP capabilities within a single-chip solution. The ADSP-BF514 lacks the Ethernet MAC found in the BF518 variants; choose accordingly if network connectivity is required. Consider the available on-chip memory configuration and the need for external SDRAM or asynchronous memory interfaces based on application data throughput requirements.

Digital Signal Processor Dsp Part Context

The ADSP-BF514 is part of the Blackfin family, which shares code compatibility across members. It sits between the lower-end BF512 and the higher-end BF518 in terms of peripheral integration, specifically lacking the IEEE 802.3 Ethernet MAC present in the BF518/BF518F16 models but retaining the RSI controller and standard serial interfaces.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-BF512KSWZ-3 is a compatible alternative with fewer peripherals (no RSI). The ADSP-BF516KSWZ-3 offers additional RSI support. For automotive qualified versions, consider the ADSP-BF514F16 series if flash memory integration is not required, or verify specific automotive qualification status in the ordering guide.
