Product details
Overview
ADSP-BF700KCPZ-1 from Analog Devices is a Blackfin+ embedded processor IC featuring a 400 MHz dual-MAC core, 136 kB parity-protected L1 SRAM (64 kB instruction + 64 kB data + 8 kB scratchpad), 256 kB ECC-protected L2 SRAM, and AEC-Q100 qualification for automotive control systems. It integrates dual CAN, USB 2.0 HS OTG, two UARTs, two SPORTs, PPI, SD/SDIO, and crypto hardware accelerators.
For engineers reviewing the ADSP-BF700KCPZ-1 datasheet, ADSP-BF700KCPZ-1 pinout, ADSP-BF700KCPZ-1 application, or ADSP-BF700KCPZ-1 equivalent, this page delivers verified core architecture details, memory mapping, peripheral timing constraints, and automotive-grade power management specifications - all confirmed for the exact 88-lead LFCSP_VQ package variant.
Technical Context
The ADSP-BF700KCPZ-1 implements a modified Harvard architecture with separate 64 kB L1 instruction and 64 kB L1 data SRAM banks, each supporting multi-parity-bit protection and configurable cache modes. Its Blackfin+ core executes two 16-bit MACs or one 32-bit MAC per cycle, with 40-bit accumulators, dual 40-bit ALUs, and video-specific ALU units.
Peripherals are managed via a hierarchical system fabric: the System Event Controller (SEC) handles prioritized interrupt routing to IVG11, while the Trigger Routing Unit (TRU) enables autonomous DMA chain triggering without CPU intervention. Memory access uses a unified 32-bit address space with dedicated 64-bit L2 interface and optional L3 DDR2/LPDDR support (CSP_BGA only).

FAQ
What is the maximum operating frequency of the ADSP-BF700KCPZ-1?
The ADSP-BF700KCPZ-1 is rated for a maximum SYSCLK of 200 MHz, as specified in Table 1 of the Rev. D datasheet. This speed grade distinguishes it from higher-performance variants like the ADSP-BF701KCPZ-1 (400 MHz). Core timing is derived from CLKIN via an internal PLL, and all L1 memory accesses meet timing at this frequency with proper power delivery and thermal management.
Does the ADSP-BF700KCPZ-1 include on-chip ADC functionality?
No, the ADSP-BF700KCPZ-1 does not integrate an analog-to-digital converter. According to Table 1 in the datasheet, ADC capability is present only in the ADSP-BF702/704/706 variants. The ADSP-BF700KCPZ-1 relies on external ADCs interfaced via its PPI, SPORT, or SPI peripherals for analog signal acquisition.
Is the ADSP-BF700KCPZ-1 qualified for automotive applications?
Yes, the ADSP-BF700KCPZ-1 is AEC-Q100 qualified (Grade 3, −40°C to +85°C ambient), as explicitly stated in the FEATURES section of the datasheet. This qualification covers stress testing for temperature cycling, humidity, vibration, and ESD - validating its use in engine control, body electronics, and ADAS subsystems.
What memory types and capacities are integrated in the ADSP-BF700KCPZ-1?
The ADSP-BF700KCPZ-1 integrates 136 kB of L1 SRAM (64 kB instruction, 64 kB data, 8 kB scratchpad) with multi-parity-bit protection, and 256 kB of L2 SRAM with ECC protection. It also includes 512 kB of L2 ROM for boot and security code. No L3 DDR2/LPDDR interface is present - that feature is exclusive to CSP_BGA packages (e.g., ADSP-BF701KBCZ-1).
Which package type does the ADSP-BF700KCPZ-1 use, and is it RoHS compliant?
The ADSP-BF700KCPZ-1 uses an 88-lead LFCSP_VQ (QFN) package measuring 12 mm × 12 mm, with an exposed thermal pad. As confirmed in the FEATURES section, this package is RoHS compliant and designed for surface-mount assembly using standard reflow profiles. Pin assignments are documented in "12 mm × 12 mm 88-Lead LFCSP (QFN) Signal Descriptions" (pages 30–35).
