Product details
Overview
ADSP-21562BSWZ4 from Analog Devices is a SHARC+ single-core floating-point DSP operating at 400 MHz, featuring 5 Mb (640 kB) L1 SRAM with parity, 256 kB L2 SRAM with ECC, and integrated FIR/IIR accelerators. It supports 32-/40-/64-bit floating-point and 32-bit fixed-point arithmetic, and targets automotive audio amplifier and head unit applications requiring deterministic real-time signal processing.
For engineers reviewing the ADSP-21562BSWZ4 datasheet, ADSP-21562BSWZ4 pinout, ADSP-21562BSWZ4 application, or ADSP-21562BSWZ4 equivalent, key selection criteria include core clock speed (400 MHz), L1 SRAM configuration (640 kB with parity), L2 memory size (256 kB ECC), package type (120-lead LQFP_EP), and AEC-Q100 qualification for automotive use.
Technical Context
The ADSP-21562BSWZ4 implements a SIMD SHARC+ core with dual processing elements (PEx/PEy), enabling parallel ALU/multiplier operations per cycle and full IEEE 32/40/64-bit floating-point support. Its memory architecture includes four configurable L1 SRAM blocks (total 5 Mb), each accessible via dedicated PM/DM buses for single-cycle core access.
It integrates a 120-lead LQFP_EP package with 0.4 mm pitch, supports DDR3/DDR3L via L3 interface (BGA-only), and includes on-chip safety features (memory protection, fault management unit) and security accelerators (crypto engine, secure boot). The device lacks link ports and full SPORTs compared to higher-grade variants.

FAQ
What is the maximum operating frequency of the ADSP-21562BSWZ4?
The ADSP-21562BSWZ4 is rated for a maximum core frequency of 400 MHz. This speed grade is confirmed in Table 1 of the ADSP-2156x datasheet Rev. D (page 3) and defines its real-time processing capability for audio algorithms such as FIR filtering and FFT computation. The device achieves this frequency with 1.0 V core supply and proper thermal management within the automotive temperature range.
Does the ADSP-21562BSWZ4 support DDR3 memory interfacing?
No, the ADSP-21562BSWZ4 does not support DDR3/DDR3L memory. According to the ADSP-2156x datasheet Rev. D (page 1), DDR3/DDR3L controller support is marked "N/A" for ADSP-21562 in Table 1. That interface is only available on BGA-packaged variants (e.g., ADSP-21563/21565/21569) and is absent in the 120-lead LQFP_EP package used by ADSP-21562BSWZ4.
What package type is used for the ADSP-21562BSWZ4?
The ADSP-21562BSWZ4 uses a 120-lead LQFP_EP (exposed pad) package with 0.4 mm lead pitch and RoHS compliance. This is explicitly stated in the "Package Options" row of Table 1 (page 3) and confirmed in the "Outline Dimensions" section (page 99) of the ADSP-2156x datasheet Rev. D. It is distinct from the 400-ball CSP_BGA option used by higher-tier variants.
Is the ADSP-21562BSWZ4 qualified for automotive applications?
Yes, the ADSP-21562BSWZ4 is AEC-Q100 qualified for automotive applications. The datasheet states "AEC-Q100 qualified for automotive applications" under "Additional Features" (page 1) and specifies Grade 2 temperature range (−40°C to +105°C ambient, or +125°C junction) in the "Automotive Products" section (page 101). This qualification covers thermal, vibration, and ESD robustness required for vehicle cabin deployment.
How much on-chip SRAM does the ADSP-21562BSWZ4 include?
The ADSP-21562BSWZ4 includes 5 Mb (640 kB) of Level 1 (L1) SRAM with parity protection and 256 kB of Level 2 (L2) SRAM with ECC. These values are specified in the "System Features" section (page 1) and Table 1 (page 3) of the ADSP-2156x datasheet Rev. D. The L1 SRAM is configurable as SRAM or cache; the L2 SRAM is fixed-function with error correction.
