Analog Devices Inc. ADSP-SC570KSWZ-42

Overview

ADSP-SC570KSWZ-42 from Analog Devices is a dual-core SHARC+ DSP with integrated Arm Cortex-A5 processor in 176-lead LQFP_EP package, operating at up to 450 MHz per SHARC+ core and 450 MHz for the Arm core. It delivers 384 kB L1 SRAM per SHARC+ core, 256 kB L2 cache, and supports 32-/40-/64-bit floating-point arithmetic. Designed for automotive audio processing, it integrates two CAN 2.0 controllers, three UARTs, and AEC-Q100 qualification.

For engineers reviewing the ADSP-SC570KSWZ-42 datasheet, ADSP-SC570KSWZ-42 pinout, ADSP-SC570KSWZ-42 application, or ADSP-SC570KSWZ-42 equivalent, key selection criteria include SHARC+ core frequency (450 MHz), Arm Cortex-A5 clock (450 MHz), L1 SRAM configuration (384 kB ×1 SHARC+ core), LQFP-176 RoHS-compliant packaging, and automotive-grade thermal range (−40°C to +105°C).

Technical Context

The ADSP-SC570KSWZ-42 implements a heterogeneous dual-domain architecture: one SHARC+ core (450 MHz) paired with an Arm Cortex-A5 core (450 MHz/800 DMIPS), sharing a 1 MB L2 SRAM with ECC protection and connected via system crossbar and DMA subsystem. Its memory hierarchy includes parity-protected 32 kB L1 instruction and data caches for Arm, and configurable 384 kB L1 SRAM for SHARC+.

Peripherals include dual CAN 2.0 controllers, three UARTs, three I²C interfaces, two SPI plus quad-SPI, eight timers, one EMAC (10/100 Mbps), one USB 2.0 HS PHY, and an 8-channel 12-bit HADC - all mapped to GPIO ports A–D (64 + 20 pins total) in the LQFP package. Security features include cryptographic hardware accelerators, TrustZone support, and fast secure boot with IP protection.

FAQ

What is the maximum operating frequency of the SHARC+ core in ADSP-SC570KSWZ-42?

The SHARC+ core in ADSP-SC570KSWZ-42 operates at a maximum frequency of 450 MHz. This is confirmed in Table 2 of the official datasheet (Rev. C, May 2024), which specifies "SHARC+ Core1 (MHz, Max): 450" for ADSP-SC570 variants. The ADSP-SC570KSWZ-42 does not include a second SHARC+ core - only the ADSP-SC572/SC573 and ADSP-2157x series do.

Does ADSP-SC570KSWZ-42 support DDR memory interfaces?

No, ADSP-SC570KSWZ-42 does not integrate a DDR3/DDR2/LPDDR1 controller. As shown in Table 2, the "DDR3/DDR2/LPDDR1 Controller (16-bit)" feature is marked "N/A" for ADSP-SC570 and ADSP-21571. Instead, the device relies on its 1 MB on-chip L2 SRAM with ECC and external parallel flash or serial NOR via SPI for code storage.

What package type and thermal characteristics apply to ADSP-SC570KSWZ-42?

ADSP-SC570KSWZ-42 uses a 176-lead LQFP_EP (exposed pad) package with 24 mm × 24 mm body size and 0.5 mm lead pitch. It is qualified to AEC-Q100 Grade 2, supporting operation from −40°C to +105°C ambient temperature, and includes thermal monitoring unit (TMU) with on-die temperature sensing calibrated per datasheet Section 64.

How many CAN interfaces does ADSP-SC570KSWZ-42 provide, and are they fully compliant?

ADSP-SC570KSWZ-42 integrates two fully compliant CAN 2.0B controllers (CAN0 and CAN1), each supporting standard and extended frame formats, bit rates up to 1 Mbps, and automatic retransmission. These are documented in the "PERIPHERALS" block diagram (Page 2) and Table 1 ("CAN2.0: 2") of the datasheet Rev. C.

Is ADSP-SC570KSWZ-42 pin-compatible with other SC57x variants in the same package?

Yes, ADSP-SC570KSWZ-42 is pin-compatible with ADSP-SC571KSWZ-42 and ADSP-21571KSWZ-42 in the 176-lead LQFP_EP package. All share identical ball/lead assignments, GPIO multiplexing, power sequencing, and reset behavior - enabling drop-in replacement where performance or qualification requirements align.
