ADSP-BF514KSWZ-4

Digital Signal Processor Dsp Overview

The ADSP-BF514KSWZ-4 is a Blackfin embedded processor from Analog Devices, operating at a maximum clock frequency of 400 MHz. It utilizes a RISC-like architecture with two 16-bit MACs and two 40-bit ALUs. The device features 116 Kbytes of on-chip memory, including configurable L1 instruction and data SRAM/cache blocks. It is housed in a 176-lead LQFP_EP package with an exposed pad. Key peripherals include two UARTs, two SPI interfaces, two SPORTs, an RSI controller for MMC/SD/SDIO, and a parallel peripheral interface (PPI). The processor supports flexible booting options and includes code security via Lockbox technology.

Digital Signal Processor Dsp Feature Summary

• Blackfin core with dual 16-bit MACs, 40-bit ALUs, and SIMD multimedia capabilities
• 116 Kbytes of on-chip memory with configurable L1 SRAM and cache
• Rich peripheral set including Ethernet MAC (BF518 only), RSI, TWI, SPORTs, and PPI
• Supports external SDRAM and asynchronous memory via glueless EBIU

Digital Signal Processor Dsp Applications

• Industrial motor control and automation systems
• Portable medical devices and instrumentation
• Consumer electronics requiring low power and high performance
• Embedded network-connected applications

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'KSWZ-4' against the manufacturer's current ordering guide to confirm package type, temperature range, and speed grade. Ensure compatibility with development tools such as VisualDSP++ for software implementation. Check for automotive qualification requirements if applicable, as some variants in this family are qualified for automotive applications.

Digital Signal Processor Dsp Selection Notes

Select the ADSP-BF514KSWZ-4 when a balance of processing power and peripheral integration is required without the Ethernet MAC found in the BF518 variant. Consider the 176-lead LQFP_EP package for board layout constraints. Evaluate memory configuration needs, as L1 memory can be partitioned between instruction and data cache or SRAM based on application latency requirements.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-BF51x Blackfin family, which shares code compatibility across members like the BF512, BF514, BF516, and BF518. The BF514 specifically lacks the integrated Ethernet MAC present in the BF518 but retains other key peripherals like RSI and SPORTs. It is designed for applications needing robust signal processing and system integration in a single chip.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes within the same family include the ADSP-BF512, ADSP-BF516, and ADSP-BF518, provided pinout and peripheral requirements align. Verify that the replacement part number matches the required speed grade (400 MHz) and package (LQFP_EP). Cross-model generic features do not guarantee identical peripheral availability or memory sizes.
