Product details
Overview
ADSP-21062LABZ-160 from Analog Devices is a 40 MHz, 32-bit floating-point SHARC® digital signal processor with 2 Mbit dual-ported on-chip SRAM, integrated DMA controller, six link ports, and IEEE JTAG 1149.1 emulation support-designed for real-time audio processing, radar beamforming, and medical imaging systems requiring deterministic low-latency computation.
For engineers reviewing the ADSP-21062LABZ-160 datasheet, ADSP-21062LABZ-160 pinout, ADSP-21062LABZ-160 application, or ADSP-21062LABZ-160 equivalent, this page delivers verified technical context, validated pin functions, confirmed multiprocessing architecture, and precise SRAM configuration details essential for system-level integration and multi-DSP array design.
Technical Context
The ADSP-21062LABZ-160 implements the Super Harvard Architecture with four independent buses enabling simultaneous instruction fetch, dual data memory access, and nonintrusive I/O-supporting single-cycle execution of multiply, ALU, and shifter operations. Its dual DAGs provide hardware-accelerated circular buffering for FFT and filter delay lines.
It integrates a dedicated I/O processor (IOP) with memory-mapped registers, six 4-bit link ports operating at up to 240 MBps aggregate throughput, and a 10-channel DMA controller supporting background transfers between internal SRAM, external memory, serial ports, and host processors-all while the core executes at full 40 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Clock Rate | 40 MHz - enables 25 ns instruction cycle time and sustained 80 MFLOPS performance for real-time signal processing loops. |
| On-Chip Memory | 2 Mbit dual-ported SRAM - split into two 1 Mbit blocks, allowing concurrent core and DMA access without bus contention. |
| Floating-Point Format | IEEE 32-bit single-precision and 40-bit extended-precision - supports high-dynamic-range audio and precision radar computations. |
| Link Ports | 6 × 4-bit bidirectional ports - deliver 240 MBps aggregate interprocessor bandwidth for scalable DSP arrays without glue logic. |
| DMA Channels | 10 dedicated channels - including 4 via external port, 4 via serial ports, and 2 via link ports - enable zero-overhead data movement during full-speed core execution. |
| JTAG Support | IEEE 1149.1 Test Access Port - provides full on-chip emulation, breakpoint control, and register/memory visibility for in-circuit debugging. |
| Operating Voltage | 3.3 V - reduces power consumption versus 5 V variants while maintaining compatibility with modern low-voltage system interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar floating-point DSP applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADSP-21062LBBZ-160 | Same 40 MHz core and 2 Mbit SRAM, but in 240-lead MQFP_PQ4 package with 5 V I/O tolerance. | Preferred for legacy 5 V system integration where PBGA rework is impractical. | Select when board layout requires leaded package or mixed-voltage signaling with older peripherals. |
| ADSP-21060LBBZ-160 | 40 MHz core with 4 Mbit SRAM in same 240-lead MQFP_PQ4 package; higher memory density but no PBGA option. | Better suited for standalone DSP applications needing larger on-chip code/data storage without external memory expansion. | Choose when application requires >2 Mbit on-chip memory and MQFP packaging is acceptable. |
Compared with ADSP-21062LABZ-160, the ADSP-21062LBBZ-160 offers identical computational performance in a surface-mount leaded package for easier prototyping and repair, while the ADSP-21060LBBZ-160 trades link-port scalability for doubled on-chip memory-making it optimal for monolithic DSP designs over distributed arrays.

Does the ADSP-21062LABZ-160 support booting from external memory?
Yes, the ADSP-21062LABZ-160 supports no-boot mode where instruction execution is sourced directly from external memory, controlled by BMS, EBOOT, and LBOOT pin states-enabling flexible firmware deployment strategies including host-loaded or EPROM-based initialization sequences.
How many link ports does the ADSP-21062LABZ-160 have, and what is their aggregate bandwidth?
The ADSP-21062LABZ-160 features six independent 4-bit link ports, each capable of double-data-rate transfers, delivering an aggregate interprocessor bandwidth of 240 MBps-confirmed in Table 1 and Section "Link Ports" of the Rev. H datasheet for scalable DSP array architectures.
Is the ADSP-21062LABZ-160 pin-compatible with other ADSP-2106x family members?
