Analog Devices Inc. ADSP-21573CBCZ-5

Overview

ADSP-21573CBCZ-5 from Analog Devices is a dual-core SHARC+ DSP with integrated Arm Cortex-A5 processor, operating at 500 MHz per SHARC+ core and 500 MHz for the Arm core. It delivers 800 DMIPS, supports 32-/40-/64-bit floating-point arithmetic, and integrates 3 MB L1 SRAM (384 kB per core), 1 MB L2 SRAM with ECC, and dual CAN 2.0 interfaces - deployed in automotive audio domain controllers and high-fidelity active noise cancellation systems.

For engineers reviewing the ADSP-21573CBCZ-5 datasheet, ADSP-21573CBCZ-5 pinout, ADSP-21573CBCZ-5 application, or ADSP-21573CBCZ-5 equivalent, key selection criteria include dual-core SHARC+ clock speed, L1 SRAM partitioning, Arm TrustZone security support, 400-ball CSP_BGA package compatibility, and AEC-Q100 qualification for automotive thermal operation.

Technical Context

The ADSP-21573CBCZ-5 implements a heterogeneous dual-domain architecture: one Arm Cortex-A5 core handles OS-driven tasks (Linux/FreeRTOS), while two SHARC+ cores execute deterministic, low-latency signal processing - coordinated via a system crossbar and shared L2 SRAM with ECC. Memory coherency is maintained through hardware-managed cache controllers and dedicated requester/completer ports.

Its peripheral subsystem includes dual CAN 2.0 controllers, three UARTs, four full SPORTs, S/PDIF Rx/Tx, ASRCs, precision clock generators, and an EMAC supporting IEEE 1588 - all routed through the Signal Routing Unit (SRU) and managed by the System Control Unit with fault monitoring and thermal management.

FAQ

What is the maximum operating frequency of each SHARC+ core in the ADSP-21573CBCZ-5?

The ADSP-21573CBCZ-5 features two SHARC+ cores, each operating at a maximum frequency of 500 MHz. This clock speed is confirmed in Table 2 of the Rev. C datasheet and enables sustained 5000 MMACS performance per core for real-time audio and control algorithms. The ADSP-21573CBCZ-5 achieves this frequency under specified VDD_INT = 1.0 V and industrial temperature conditions.

Does the ADSP-21573CBCZ-5 support DDR3 memory interfacing?

Yes, the ADSP-21573CBCZ-5 includes a 16-bit DDR3/DDR2/LPDDR1 controller, as documented in Table 2 and the "Memory" section of the datasheet. It supports DDR3L (1.35 V) and standard DDR3 (1.5 V) devices, with configurable timing parameters for reliable operation up to 533 MHz data rate. This interface is accessible only in the 400-ball CSP_BGA package variant.

Is the ADSP-21573CBCZ-5 qualified for automotive applications?

Yes, the ADSP-21573CBCZ-5 is AEC-Q100 qualified for automotive use (Grade 2: −40°C to +105°C ambient). Its qualification is explicitly stated in the "Additional Features" section and Table 3 of the datasheet. While not rated for Grade 1 (−40°C to +125°C), it is widely deployed in head units, amplifier modules, and ADAS audio processors where under-dash mounting is typical.

How many CAN 2.0 interfaces does the ADSP-21573CBCZ-5 integrate?

The ADSP-21573CBCZ-5 integrates two independent CAN 2.0B controllers, as confirmed in the "Peripherals" block diagram (Figure 1), Table 1 ("Common Product Features"), and the "Processor Peripherals" section. Each controller supports bit rates up to 1 Mbps, message filtering, and FIFO buffering - enabling robust communication with ECUs in automotive networks.

What debug and trace capabilities are available on the ADSP-21573CBCZ-5?

The ADSP-21573CBCZ-5 includes Arm CoreSight debug infrastructure with ETM (Embedded Trace Macrocell) support for instruction trace, plus SHARC-specific debug units including JTAG, SWD, and real-time watchpoint units. These capabilities are detailed in the "System Debug" section and enable cycle-accurate profiling of both Arm and SHARC+ code execution - essential for latency-critical audio development.
