Product details
Overview
ADSP-21565KSWZ10 from Analog Devices is a SHARC+ single-core floating-point DSP engineered for high-performance audio and signal processing in automotive and professional systems. It operates at up to 1 GHz, integrates 5 Mb L1 SRAM with parity, supports 32-/40-/64-bit floating-point arithmetic, and features hardware FIR/IIR accelerators running at full core speed - deployed in digital cockpit audio amplifiers and active noise cancellation (ANC) modules.
For engineers reviewing the ADSP-21565KSWZ10 datasheet, ADSP-21565KSWZ10 pinout, ADSP-21565KSWZ10 application, or ADSP-21565KSWZ10 equivalent, key selection criteria include its AEC-Q100 qualification, 400-ball CSP_BGA package (17 mm × 17 mm, 0.8 mm pitch), DDR3L interface capability, and dual-precision clock generators for synchronized multi-channel audio timing.
Technical Context
The ADSP-21565KSWZ10 implements a SIMD SHARC+ core with two parallel processing elements (PEx/PEy), each supporting IEEE 32-/64-bit floating-point and 40-bit extended-precision operations in single-cycle execution. Its memory architecture includes four configurable L1 SRAM blocks (total 5 Mb) with independent DM/PM buses enabling simultaneous instruction fetch and dual-data transfers per cycle.
System-level integration includes a dedicated SHARC fabric connecting FIR/IIR accelerators directly to L1 memory at CCLK speed, bypassing system fabric latency; plus an L2 SRAM block (1 MB, ECC-protected) and L3 DDR3/DDR3L interface optimized for low-power automotive operation across –40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Type | SHARC+ single-core SIMD DSP with instruction set compatibility to ADSP-2106x through ADSP-SC5xx families |
| Max Core Frequency | 1 GHz - enables real-time execution of complex ANC/RNC algorithms with sub-50 µs loop latency |
| L1 Memory | 5 Mb (640 kB) SRAM with parity - configurable as cache or tightly coupled memory for zero-wait-state core access |
| L2 Memory | 1 MB (8 Mb) SRAM with ECC - used for coefficient storage, DMA descriptor tables, and accelerator data buffers |

FAQ
What is the maximum operating frequency of the ADSP-21565KSWZ10?
The ADSP-21565KSWZ10 is rated for up to 1 GHz operation across the full automotive temperature range (–40°C to +125°C). This speed grade is validated per AEC-Q100 and enables real-time execution of computationally intensive algorithms such as 2048-tap FIR filters and multi-channel beamforming - all within strict latency budgets required for ANC and digital cockpit applications. The ADSP-21565KSWZ10 achieves this performance with dynamic power management and on-chip voltage regulation.
Does the ADSP-21565KSWZ10 support secure boot and firmware encryption?
Yes, the ADSP-21565KSWZ10 includes a crypto hardware accelerator and fast secure boot capability. It supports authenticated boot from either on-chip 7 kB OTP memory or external SPI flash, with AES-128/256 encryption and SHA-256 integrity verification. The secure boot process is initiated automatically on RESET_N deassertion and enforces code signing before any user application executes - a critical feature for automotive ECUs and certified professional audio equipment where IP protection is mandatory. The ADSP-21565KSWZ10 implements this without external security chips.
What memory interfaces does the ADSP-21565KSWZ10 provide for external storage?
The ADSP-21565KSWZ10 provides a 16-bit DDR3/DDR3L SDRAM interface via its L3 memory controller, supporting data rates up to 800 Mbps. It also includes one octal SPI, two quad SPI, and one standard SPI interface for flash memory expansion - enabling boot from QSPI NOR and firmware updates via OSPI. Unlike earlier SHARC generations, the ADSP-21565KSWZ10 does not integrate NAND or eMMC controllers; external storage is limited to DDR3L and SPI-based devices. All interfaces are accessible in the 400-ball CSP_BGA package.
Is the ADSP-21565KSWZ10 pin-compatible with other ADSP-2156x variants?
Yes, the ADSP-21565KSWZ10 shares identical 400-ball CSP_BGA mechanical and electrical pinout with ADSP-21562/21563/21566/21567/21569 in the same package variant (KSWZ suffix). This includes matching ball assignments for power, ground, DDR3L, DAI, and debug signals. However, functional differences exist - for example, ADSP-21562 lacks link ports and has reduced timer count - so PCB layout is reusable but firmware and peripheral initialization must match the specific variant's capabilities. The ADSP-21565KSWZ10 is not pin-compatible with LQFP-packaged variants.
What development tools are officially supported for the ADSP-21565KSWZ10?
Analog Devices officially supports CrossCore Embedded Studio (CCES) v2.12.0+ for ADSP-21565KSWZ10 firmware development, including C/C++ compilation, SHARC+ SIMD intrinsic optimization, and real-time debugging via JTAG/SWD. Hardware tools include the ICE-1000/2000 emulators and ADZS-ICE-1000-EMULATOR. Evaluation is enabled by the EZ-KIT Lite (ADZS-21569-EZLITE), which supports ADSP-21565KSWZ10 via socket adapter. Analog Devices also provides SHARC+ libraries (libdsp, libfilter), SigmaStudio integration for audio algorithm design, and AEC-Q100 test reports - all accessible through the ADSP-21565KSWZ10 product page on analog.com.
