Technical Context

The ADZS-21371-EZLITE implements a complete reference platform for the ADSP-21371 processor in a 208-lead LQFP_EP package, with dedicated routing for DAI peripherals including S/PDIF Tx/Rx, eight SPORTs, four PCGs, IDP, and DPI resources like SPI, TWI, UART, and timers. It supports external SDRAM (up to 256 MB per bank) and asynchronous memory via the 32-bit external port with AMI controller.

Board-level features include JTAG debug interface compliant with IEEE 1149.1, on-board USB-to-JTAG emulator (via ADZS-USB-ICE), configurable clock sources (crystal + PLL), regulated 1.0 V/3.3 V/5.0 V power domains, and header-accessible GPIO, PWM, and analog I/O signals - all aligned with the ADSP-21371's dual-clock-domain architecture (core @ 266 MHz, peripheral @ programmable PCLK).

FAQ

What is the ADZS-21371-EZLITE used for?

The ADZS-21371-EZLITE is an evaluation board designed specifically for the ADSP-21371 SHARC processor. It enables engineers to develop, debug, and validate real-time audio algorithms, motor control firmware, and high-speed signal processing applications. The board provides full access to the ADSP-21371's DAI and DPI peripherals, including S/PDIF, eight serial ports, PWM outputs, and precision clock generators - making it ideal for prototyping automotive audio head units and professional digital mixing consoles.

Does the ADZS-21371-EZLITE support the ADSP-21375 processor?

No, the ADZS-21371-EZLITE is hardware-optimized for the ADSP-21371 and is not compatible with the ADSP-21375. Key differences include the ADSP-21371's 1 Mbit SRAM, 4 Mbit ROM, S/PDIF transceiver, and 16 PWM outputs - none of which are present in the ADSP-21375. The board's power regulation, clock tree, and peripheral routing assume the ADSP-21371's specific memory map, pinout, and feature set. Using the ADSP-21375 would require significant redesign and is not supported.

What software tools are required to use the ADZS-21371-EZLITE?

To use the ADZS-21371-EZLITE, engineers need Analog Devices' CrossCore Embedded Studio (CCES), the SHARC Processor Software Development Kit (SHARC SDK), and the ADSP-21371 EZ-KIT Board Support Package (BSP). These tools provide compiler, debugger, device drivers, example projects (e.g., S/PDIF loopback, FIR filtering, FFT-based spectrum analysis), and hardware abstraction layers. USB-based JTAG debugging is enabled out-of-the-box with the included ADZS-USB-ICE emulator.

Can the ADZS-21371-EZLITE operate without external memory?

Yes, the ADZS-21371-EZLITE can execute code directly from the ADSP-21371's on-chip 1 Mbit SRAM and 4 Mbit mask-ROM, eliminating dependency on external memory during initial boot and basic algorithm testing. However, for large audio buffers, multi-channel TDM streams, or complex filter banks, the board's 128 MB DDR SDRAM and 4 MB SPI Flash are essential to extend memory capacity beyond on-chip limits while maintaining deterministic real-time performance.

Is the ADZS-21371-EZLITE RoHS compliant and qualified for automotive use?

Yes, the ADZS-21371-EZLITE is RoHS compliant and built with components rated for industrial temperature range (−40°C to +85°C). While the board itself is not AEC-Q200 qualified, it hosts the ADSP-21371 - a processor explicitly designed for automotive audio applications and supported by Analog Devices' automotive-grade documentation, qualification reports, and functional safety resources (e.g., ISO 26262-ready software libraries).
