Product details
Overview
ADSP-BF706KCPZ-3 from Analog Devices is a Blackfin+ embedded processor with 400 MHz core performance, dual 16-bit or single 32-bit MAC per cycle, 136 kB parity-protected L1 SRAM (64 kB instruction + 64 kB data + 8 kB scratchpad), 1 MB ECC-protected L2 SRAM, and AEC-Q100 qualification for automotive control systems.
For engineers reviewing the ADSP-BF706KCPZ-3 datasheet, ADSP-BF706KCPZ-3 pinout, ADSP-BF706KCPZ-3 application, or ADSP-BF706KCPZ-3 equivalent, this page delivers verified core architecture details, memory mapping, peripheral integration (2× CAN, USB 2.0 HS OTG, 2× UART, 2× SPORT), security features (crypto engine, secure boot), and package-specific electrical and timing specifications.
Technical Context
The ADSP-BF706KCPZ-3 implements a modified Harvard architecture with separate 64 kB L1 instruction and 64 kB L1 data SRAM blocks-both multi-parity-bit protected-and an 8 kB scratchpad SRAM. Its Blackfin+ core integrates two 16-bit multipliers, one 32-bit multiplier, two 40-bit ALUs, and supports simultaneous dual 16-bit MAC or single 32-bit MAC per cycle.
It features a hierarchical memory system: L1 operates at full core speed; L2 provides unified 1 MB ECC-protected SRAM accessible via a 64-bit interface at SYSCLK frequency; and L3 interface (CSP_BGA only) enables 16-bit DDR2/LPDDR support up to 200 MHz-though ADSP-BF706KCPZ-3 uses the 88-lead LFCSP package and excludes L3.
