Product details
Overview
AD21369WBSWZ102 from Analog Devices is a 400 MHz, 32-bit/40-bit floating-point SHARC® DSP optimized for high-fidelity automotive audio processing. It integrates 2 Mbits of on-chip SRAM, 6 Mbits of mask-programmable ROM, eight serial ports, one S/PDIF transceiver, and four asynchronous sample rate converters (SRC) with 128 dB performance. It serves as the real-time audio signal processor in premium car infotainment head units.
For engineers reviewing the AD21369WBSWZ102 datasheet, AD21369WBSWZ102 pinout, AD21369WBSWZ102 application, or AD21369WBSWZ102 equivalent, key selection criteria include SIMD computational throughput (2.4 GFLOPS), dedicated audio peripherals (S/PDIF, SRC, PCG), on-chip security (64-bit JTAG key), and dual-package availability (256-ball BGA_ED or 208-lead LQFP_EP).
Technical Context
The AD21369WBSWZ102 implements a dual-processing-element SIMD core (PEx/PEy), each with ALU, multiplier, shifter, and 40-bit register file, enabling parallel execution of identical instructions on independent data streams. Its enhanced Harvard architecture supports simultaneous single-cycle fetch of one instruction and four operands via separate 64-bit PM/DM buses and instruction cache.
Peripherals are partitioned into two clock domains: the core domain (400 MHz) hosts memory controllers and timers, while the I/O processor domain (PCLK) manages DAI, DPI, S/PDIF, SRC, PWM, and external port interfaces-including AMI (14M/16M-word banks) and SDRAM controller (62M/64M-word banks) with 32-bit bus width and 664 MB/s peak throughput.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Frequency | 400 MHz - enables 2.5 ns instruction cycle time and 2.4 GFLOPS SIMD performance for real-time FIR/IIR filtering. |
| On-Chip Memory | 2 Mbits SRAM + 6 Mbits ROM - supports full audio algorithm execution without external code fetch; configurable as 64k × 32-bit data or 42k × 48-bit instructions. |

FAQ
What is the maximum SDRAM bandwidth supported by AD21369WBSWZ102?
AD21369WBSWZ102 supports up to 664 MB/s SDRAM bandwidth using its 32-bit wide bus and 166 MHz clock. This is achieved through the integrated SDRAM controller with programmable timing parameters, enabling glueless interface to industry-standard SDRAM devices across four independent banks (62M–64M words each). The bandwidth is sufficient for real-time buffering of multi-channel, high-resolution audio streams in automotive and professional audio applications.
Does AD21369WBSWZ102 support I2S protocol natively?
Yes, AD21369WBSWZ102 supports I2S natively through its eight synchronous serial ports (SPORTs). Each SPORT can be configured for I2S mode with word lengths from 8 to 32 bits, left-justified or right-justified formats, and selectable synchronization. With two data pins per SPORT, up to 32 I2S channels are supported-enabling direct connection to multiple audio codecs such as the AD183x family without external level-shifting or protocol translation.
How does the ROM-based security feature work on AD21369WBSWZ102?
AD21369WBSWZ102 implements ROM-based security by enforcing boot-from-ROM operation and disabling unrestricted JTAG access unless a unique 64-bit customer key is scanned via the JTAG port. When enabled, the processor ignores external boot modes and prevents unauthorized reading of internal code. This hardware-enforced mechanism meets automotive OEM requirements for firmware intellectual property protection and secure over-the-air update execution.
Can AD21369WBSWZ102 perform sample rate conversion between 44.1 kHz and 48 kHz audio streams?
Yes, AD21369WBSWZ102 includes four independent asynchronous sample rate converters (SRC) rated at 128 dB SNR. These SRC units operate without shared clock domains and can convert between arbitrary sample rates-including 44.1 kHz (CD standard) and 48 kHz (professional audio standard)-with minimal jitter and no audible artifacts. This capability is essential for mixing audio from disparate sources like Bluetooth A2DP and USB DAC in automotive head units.
What development tools are recommended for AD21369WBSWZ102 firmware development?
Analog Devices' CrossCore Embedded Studio (CCES) is the officially supported IDE for AD21369WBSWZ102, providing C/C++ compilation, SHARC-specific optimization, real-time debugging via JTAG, and libraries for audio processing (e.g., SigmaStudio-compatible frameworks). Hardware debug support requires the ICE-1000 or ICE-2000 emulator. Reference schematics and HDL for the EZ-KIT evaluation board (ADSP-21369 EZ-KIT Lite) are available to accelerate bring-up and validation.
