ADSP-BF514BBCZ-3

Digital Signal Processor Dsp Overview

The ADSP-BF514BBCZ-3 is a Blackfin embedded processor featuring a 400 MHz maximum clock frequency. It utilizes the Micro Signal Architecture with two 16-bit MACs and two 40-bit ALUs. The device includes 116 Kbytes of on-chip memory, comprising L1 instruction and data SRAM/cache and scratchpad memory. It operates within a voltage range of 1.14 V to 1.47 V for the core and supports I/O voltages of 1.8 V, 2.5 V, or 3.3 V. The component is housed in a 176-lead LQFP_EP package and functions within a temperature range of -40°C to +85°C.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'BBCZ-3' against the manufacturer's ordering guide to confirm package type (LQFP_EP) and speed grade (400 MHz). Ensure compatibility with required boot configurations and external memory interfaces before procurement.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high-performance signal processing with integrated Ethernet capabilities absent in lower-tier BF512 variants. Confirm that the 176-lead LQFP_EP footprint fits the PCB layout constraints and that the 1.2 V core voltage supply is available.

Digital Signal Processor Dsp Part Context

This part belongs to the ADSP-BF51x family, which shares code compatibility across the series. It differs from the BF512 by offering higher memory density and from the BF518 by lacking the integrated Ethernet MAC. It serves as a mid-range solution within the Blackfin portfolio for general-purpose DSP tasks.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-BF514BBCZ-3BRL is a BGA alternative within the same family. Verify pinout compatibility between LQFP_EP and CSP_BGA packages if considering physical replacement.
