FAQ

What is the maximum operating frequency of the SHARC+ core in ADSP-SC570BSWZ-42?

The SHARC+ core in ADSP-SC570BSWZ-42 operates at up to 450 MHz. This frequency is specified under AEC-Q100 Grade 2 conditions (−40°C to +105°C ambient) with proper power delivery and thermal management. The Arm Cortex-A5 core also runs at 450 MHz, enabling balanced compute partitioning between DSP and application layers in ADSP-SC570BSWZ-42 designs.

Does ADSP-SC570BSWZ-42 support external DDR memory?

No, ADSP-SC570BSWZ-42 does not integrate a DDR controller. Unlike ADSP-SC572/SC573 variants, this part omits the 16-bit DDR3/DDR2/LPDDR1 interface. It relies solely on its 1 MB on-chip L2 SRAM with ECC and 768 kB total L1 SRAM (384 kB per SHARC+ core) for data and program storage. External memory expansion must use SPI flash or parallel NOR/NAND via GPIO-mapped interfaces.

What package type and ball count does ADSP-SC570BSWZ-42 use?

ADSP-SC570BSWZ-42 uses a 400-ball CSP_BGA package with 17 mm × 17 mm body size and 0.5 mm ball pitch. This package is RoHS compliant and qualified for automotive applications. Pinout matches the standard ADSP-SC57x 400-ball CSP_BGA footprint, ensuring mechanical and thermal compatibility across the SC57x family.

Is ADSP-SC570BSWZ-42 AEC-Q100 qualified, and what grade does it meet?

Yes, ADSP-SC570BSWZ-42 is AEC-Q100 qualified to Grade 2, supporting operation from −40°C to +105°C ambient temperature. This qualification covers the full device - including both SHARC+ and Arm Cortex-A5 cores, memory subsystems, and all integrated peripherals such as CAN, USB, and EMAC - making it suitable for passenger compartment automotive applications like head units and display audio systems.

How many CAN 2.0 interfaces does ADSP-SC570BSWZ-42 integrate?

ADSP-SC570BSWZ-42 integrates two fully independent CAN 2.0 controllers (CAN0 and CAN1), each with dedicated message RAM, transmit/receive buffers, and error counters. Both controllers support bit rates up to 1 Mbps and are compliant with ISO 11898-1. They are accessible via dedicated CAN_TX/CAN_RX pins and require external CAN transceivers for physical layer interfacing in ADSP-SC570BSWZ-42 implementations.
