Product details
Overview
ADSP-BF701BBCZ-2 from Analog Devices is a Blackfin+ embedded processor IC delivering 400 MHz peak performance with 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), and AEC-Q100 qualification for automotive control systems requiring deterministic real-time signal processing.
For engineers reviewing the ADSP-BF701BBCZ-2 datasheet, ADSP-BF701BBCZ-2 pinout, ADSP-BF701BBCZ-2 application, or ADSP-BF701BBCZ-2 equivalent, key selection factors include its 184-ball CSP_BGA RoHS-compliant package, integrated crypto accelerators, dual CAN 2.0B interfaces, USB 2.0 HS OTG, and L2 SRAM variants up to 1 MB with ECC protection.
Technical Context
The ADSP-BF701BBCZ-2 implements a modified Harvard architecture with separate 64 kB L1 instruction and 64 kB L1 data SRAM banks-both multi-parity-bit protected-and an 8 kB dedicated scratchpad. Its Blackfin+ core integrates two 16-bit multipliers, one 32-bit multiplier, dual 40-bit ALUs, and a 72-bit ALU supporting simultaneous 16-bit operations on register pairs.
System-level infrastructure includes a 16-bit dynamic memory controller (CSP_BGA only) for DDR2/LPDDR up to 200 MHz, three MDMA controllers, two SPORTs, dual SPI host ports (2× Quad SPI + 1× Dual SPI), and hardware crypto engines enabling fast secure boot and memDMA encryption/decryption.

FAQ
What is the maximum operating temperature range for ADSP-BF701BBCZ-2?
ADSP-BF701BBCZ-2 is AEC-Q100 qualified for Grade 2 operation, meaning it is specified to function reliably from −40°C to +105°C ambient temperature. This rating covers junction temperature limits under worst-case power dissipation and board-level thermal design - critical for under-hood automotive deployment where ADSP-BF701BBCZ-2 is commonly used in body control modules and ADAS domain controllers.
Does ADSP-BF701BBCZ-2 include an integrated analog-to-digital converter (ADC)?
No, ADSP-BF701BBCZ-2 does not include an integrated ADC. As confirmed in Table 1 of the Rev. D datasheet, the ADSP-BF701 variant has "No" listed under the "4-Channel 12-Bit ADC" row. ADC functionality is present only in ADSP-BF702, BF704, BF706, and BF707 variants. Designers using ADSP-BF701BBCZ-2 must implement external ADCs via its SPORT, PPI, or SPI interfaces.
What boot sources are supported by ADSP-BF701BBCZ-2?
ADSP-BF701BBCZ-2 supports multiple boot modes configured via the BOOT[2:0] pins, including master boot from SPI flash, slave boot over USB 2.0 HS OTG, UART, or external host processor. The internal 512 kB L2 ROM contains boot code and security firmware, enabling secure boot from any selected source - a key requirement for automotive OTA update architectures using ADSP-BF701BBCZ-2.
Is ADSP-BF701BBCZ-2 pin-compatible with other ADSP-BF70x variants in the 184-ball CSP_BGA package?
Yes, all ADSP-BF70x parts in the 184-ball CSP_BGA package - including ADSP-BF701BBCZ-2, ADSP-BF702BBCZ-2, and ADSP-BF706BBCZ-2 - share identical ball maps and mechanical footprint. This allows hardware reuse across performance tiers (200–400 MHz) and memory configurations (256 kB–1 MB L2 SRAM), simplifying platform scalability for ADSP-BF701BBCZ-2-based designs.
What development tools are officially supported for ADSP-BF701BBCZ-2?
Analog Devices provides full toolchain support for ADSP-BF701BBCZ-2 via CrossCore Embedded Studio (CCES), including C/C++ compiler, assembler, debugger, and ICE-1000/2000 emulators. The EZ-KIT Lite evaluation board (part number EVAL-ADSP-BF701-EZLITE) offers immediate hardware validation with on-board JTAG, USB, CAN, and expansion headers - enabling rapid bring-up of ADSP-BF701BBCZ-2 firmware.
