Product details
Overview
ADSP-21060LKB-160 from Analog Devices is a 32-bit floating-point SHARC® digital signal processor with 4 Mbit dual-ported on-chip SRAM, 40 MIPS instruction rate at 40 MHz, IEEE 32-bit/40-bit floating-point computation units, and integrated host interface, DMA controller, six link ports, and two serial ports - deployed in high-throughput audio processing, radar beamforming, and real-time spectral analysis systems.
For engineers reviewing the ADSP-21060LKB-160 datasheet, ADSP-21060LKB-160 pinout, ADSP-21060LKB-160 application, or ADSP-21060LKB-160 equivalent, key selection criteria include its 3.3 V core operation, 240-pin MQFP_PQ4 thermally enhanced package, dual-bus Harvard architecture enabling simultaneous instruction + dual-data fetch, and glueless multiprocessing support for scalable DSP arrays.
Technical Context
The ADSP-21060LKB-160 implements the SHARC Super Harvard Architecture with four independent buses (PM/DM address/data), enabling single-cycle fetch of one instruction and two operands. Its dual data address generators (DAG1/DAG2) support hardware circular buffers and bit-reverse addressing essential for FFT and filter implementations.
It integrates a dedicated I/O processor (IOP), 10-channel DMA controller supporting background transfers up to 240 MBps, and a JTAG-compliant IEEE 1149.1 test access port for on-chip emulation - all operating under 3.3 V supply with 25 ns instruction cycle time and zero-overhead looping capability.

FAQ
What is the operating voltage specification for ADSP-21060LKB-160?
ADSP-21060LKB-160 operates at a nominal 3.3 V core supply voltage, as confirmed in the ADSP-21060L/ADSP-21062L Specifications section (Rev. H, Page 18). This distinguishes it from the 5 V ADSP-21060 variant and enables lower power consumption and compatibility with modern 3.3 V system rails. The I/O pins are 3.3 V tolerant and support mixed-voltage interfacing with appropriate level-shifting for legacy 5 V peripherals.
Does ADSP-21060LKB-160 support booting from external memory?
Yes, ADSP-21060LKB-160 supports multiple boot modes controlled by BMS, EBOOT, and LBOOT pins. It can boot from an 8-bit EPROM, a 16-/32-bit host processor via the host port, or through one 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-upgradable firmware architectures.
How many DMA channels does ADSP-21060LKB-160 provide, and what are their destinations?
ADSP-21060LKB-160 integrates a 10-channel DMA controller: four channels via the external port (for host, memory, or I/O transfers), four via serial ports (two per port), and two via link ports. Four additional shared link-port DMA channels are allocated across Serial Port 1 and the external port. All channels operate concurrently with full-speed CPU execution, enabling background data movement without compromising 40 MIPS computational throughput.
Is ADSP-21060LKB-160 pin-compatible with other SHARC processors in the ADSP-2106x family?
ADSP-21060LKB-160 shares the same 240-lead MQFP_PQ4 package and pinout with ADSP-21060KB-160 and ADSP-21060CKB-160, but differs electrically from 5 V variants due to its 3.3 V operation. It is not pin-compatible with PBGA or CQFP variants (e.g., ADSP-21060LBB-160 or ADSP-21060LCB-160), nor with ADSP-21062LKBZ-160 despite identical packaging - the latter has different SRAM configuration and memory map addressing.
What development tools are officially supported for ADSP-21060LKB-160 firmware development?
Analog Devices officially supports ADSP-21060LKB-160 with VisualDSP++ IDE (legacy) and CrossCore Embedded Studio (current). Both provide C/C++ compilation, JTAG-based debugging, and hardware-assisted profiling. Board Support Packages (BSPs) for EZ-KIT Lite evaluation boards and emulator pods (e.g., ICE-1000/2000) are available. Note that VisualDSP++ remains fully functional for ADSP-21060LKB-160 but is not updated for newer processor families.
