Product details
Overview
ADSP-21062LKSZ-133 from Analog Devices is a 32-bit floating-point SHARC® digital signal processor with 2 Mbit dual-ported on-chip SRAM, 40 MHz instruction rate (25 ns cycle), IEEE 32-bit/40-bit floating-point computation units, and integrated I/O peripherals including six link ports, two serial ports, host interface, and 10-channel DMA controller. It serves as the real-time computational core in high-bandwidth audio processing, radar beamforming, and medical imaging systems.
For engineers reviewing the ADSP-21062LKSZ-133 datasheet, ADSP-21062LKSZ-133 pinout, ADSP-21062LKSZ-133 application, or ADSP-21062LKSZ-133 equivalent, key selection criteria include its 3.3 V operation, PBGA-225 package, 240 MBps interprocessor link port throughput, and support for zero-overhead looping and hardware circular buffers in FFT and filter implementations.
Technical Context
The ADSP-21062LKSZ-133 implements the SHARC Super Harvard Architecture with four independent buses enabling simultaneous instruction fetch, dual data operand fetch, and nonintrusive I/O-achieving true parallel execution of multiply, ALU, and shifter operations per cycle. Its dual data address generators (DAG1/DAG2) provide hardware modulo and bit-reverse addressing for efficient FIR/IIR filtering and FFT butterfly computation.
Memory architecture centers on two 1 Mbit dual-ported SRAM blocks, each independently accessible by core processor and DMA/IOP in single cycles. The unified 4-gigaword address space integrates internal memory, external memory, multiprocessor memory space, and I/O-mapped registers-enabling glueless multiprocessing across up to six ADSP-2106x devices via distributed bus arbitration and broadcast writes.

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-21062LKBZ-133 | Same core, identical 2 Mbit SRAM and 40 MHz speed, but in 240-lead MQFP_PQ4 package (not PBGA) | Preferred where board-level thermal management favors exposed-pad QFP over BGA; lower I/O pin count limits external memory expansion | Select when PCB assembly process lacks BGA reflow capability or requires manual inspection of solder joints |
| ADSP-21065LKSZ-210 | Successor SHARC with 4 Mbit SRAM, 66 MHz clock, and enhanced DMA; not pin-compatible with ADSP-21062LKSZ-133 | Required for higher-throughput applications like multi-spectral imaging or wideband communications where 120 MFLOPS is insufficient | Choose only when redesigning for increased algorithmic complexity and can accommodate new footprint and voltage requirements (1.2 V core / 3.3 V I/O) |
Compared with ADSP-21062LKBZ-133, ADSP-21062LKSZ-133 offers superior thermal dissipation in high-density layouts via PBGA; compared with ADSP-21065LKSZ-210, it provides proven reliability and legacy toolchain support (VisualDSP++) for maintenance of existing audio/industrial designs without layout or firmware overhaul.

FAQ
What is the operating voltage requirement for ADSP-21062LKSZ-133?
The ADSP-21062LKSZ-133 operates at 3.3 V ± 0.3 V for both core and I/O domains. This 3.3 V specification distinguishes it from the 5 V ADSP-21062 variants and enables lower power consumption while maintaining full 40 MHz instruction rate. Power sequencing must ensure VDD ramps before applying CLKIN, and all supply pins require local 0.1 µF ceramic decoupling per Analog Devices' layout guidelines in the Rev. H datasheet.
Does ADSP-21062LKSZ-133 support booting from external memory?
Yes, ADSP-21062LKSZ-133 supports multiple boot modes controlled by BMS, EBOOT, and LBOOT pins. It can boot from an 8-bit EPROM, host processor via the 32-bit host interface, or through any of its six link ports. A no-boot mode is also available, where instruction execution begins directly from external memory-enabling flexible system initialization and field firmware updates without on-chip ROM dependency.
How many link ports does ADSP-21062LKSZ-133 have, and what is their maximum throughput?
The ADSP-21062LKSZ-133 features six independent 4-bit link ports (L1–L6), each capable of transferring 8 bits per core cycle when double-clocked. With a 40 MHz core clock, this delivers 240 MBps aggregate throughput across all six ports. Each link port has dedicated double-buffered input/output registers and programmable transmit/receive direction, making them ideal for deterministic interprocessor communication in radar and audio array systems.
Is ADSP-21062LKSZ-133 pin-compatible with other ADSP-2106x family members?
No, ADSP-21062LKSZ-133 is not pin-compatible with ADSP-21060 or ADSP-21065 variants due to differences in memory size, I/O configuration, and package-specific ball assignments. Within the ADSP-21062L subfamily, ADSP-21062LKSZ-133 shares the same 225-ball PBGA footprint with ADSP-21062LKBZ-133 only in mechanical outline-not electrical pinout-as the latter uses a 240-lead MQFP package. Always verify ball mapping against Rev. H datasheet Figure 34.
What development tools are supported for ADSP-21062LKSZ-133 firmware development?
ADSP-21062LKSZ-133 is fully supported by VisualDSP++® IDE (legacy) and CrossCore® Embedded Studio (current). Both provide C/C++ compilation, JTAG-based on-chip debugging, and real-time profiling. Board Support Packages (BSPs) for EZ-KIT Lite evaluation boards and middleware add-ins-including SHARC software modules for FFT, FIR, and audio codecs-are available from analog.com. Legacy projects may continue using VisualDSP++; new designs should adopt CrossCore for ongoing toolchain support.
