Product details
Overview
ADSP-21061LKB-160 from Analog Devices is a 3.3 V, 160 MHz SHARC DSP microcomputer with 1 Mbit dual-ported on-chip SRAM, IEEE 32-bit/40-bit floating-point computation units (ALU, multiplier, shifter), and integrated I/O peripherals including two synchronous serial ports, host interface, DMA controller, and JTAG emulation port. It serves as a high-performance signal processor in real-time communications infrastructure and medical imaging systems.
For engineers reviewing the ADSP-21061LKB-160 datasheet, ADSP-21061LKB-160 pinout, ADSP-21061LKB-160 application, or ADSP-21061LKB-160 equivalent, key selection criteria include its 160 MHz clock rate, 3.3 V core supply, 225-ball PBGA package, dual-ported memory architecture, and multiprocessing support for glueless multi-DSP systems.
Technical Context
The ADSP-21061LKB-160 implements the Super Harvard Architecture with four independent buses enabling simultaneous instruction fetch, dual data fetch, and nonintrusive I/O. Its dual data address generators (DAG1/DAG2) support hardware circular buffers and bit-reverse addressing essential for FFT and filter implementations.
It features an on-chip instruction cache enabling three-bus operation per cycle, zero-overhead looping, and IEEE JTAG 1149.1 test access. The processor executes all instructions in single cycle at 160 MHz, delivering 80 MFLOPS sustained and 120 MFLOPS peak floating-point performance using 32-bit single-precision or 40-bit extended-precision formats.

FAQ
What is the maximum operating frequency of the ADSP-21061LKB-160?
The ADSP-21061LKB-160 operates at a maximum clock frequency of 160 MHz, corresponding to a 20 ns instruction cycle time. This speed grade is validated under 3.3 V supply conditions per the ADSP-21061L specifications section of the Rev. D datasheet. All computational units-including the ALU, multiplier, and shifter-execute instructions in single cycle at this rate, delivering 80 MFLOPS sustained floating-point performance.
Does the ADSP-21061LKB-160 support IEEE JTAG 1149.1 debugging?
Yes, the ADSP-21061LKB-160 includes a fully compliant IEEE JTAG 1149.1 test access port (TAP) with dedicated TMS, TDI, TDO, and TCK pins. This enables boundary scan testing, in-circuit emulation, and real-time debug capabilities using Analog Devices EZ-ICE emulators or third-party JTAG probes. The JTAG interface provides full visibility into internal registers, memory, and program flow without impacting real-time system timing.
How much on-chip memory does the ADSP-21061LKB-160 provide, and what is its architecture?
The ADSP-21061LKB-160 integrates 1 Mbit of on-chip SRAM organized as two independent 0.5 Mbit dual-ported blocks. Each block supports simultaneous access by the core processor and either the DMA controller or I/O processor-enabling concurrent instruction fetch, data load/store, and peripheral I/O without bus contention. Memory can be configured as 32k words of 32-bit data, 64k words of 16-bit data, or combinations up to the full 1 Mbit capacity.
Is the ADSP-21061LKB-160 pin-compatible with other SHARC processors?
The ADSP-21061LKB-160 is pin-compatible with the ADSP-21060 and ADSP-21062 in the 225-ball PBGA package variant, as confirmed in the "Porting Code" section of the Rev. D datasheet. However, link port pins present on the ADSP-21060/21062 are designated as no-connects on the ADSP-21061LKB-160. Memory organization differs (8 vs. 16 columns per bank), and 2-D DMA for SPORTs is not supported-requiring minor code adjustments during migration.
What I/O interfaces are integrated into the ADSP-21061LKB-160?
The ADSP-21061LKB-160 integrates two synchronous serial ports (SPORT0/SPORT1), a 32-bit host processor interface, a 6-channel DMA controller, an external memory/peripheral bus (32-bit address, 48-bit data), interval timer, and JTAG test port. Both serial ports support TDM multichannel mode, programmable word length (3–32 bits), μ-law/A-law companding, and independent transmit/receive clocks-enabling direct connection to codecs, ADCs, DACs, and FPGAs without glue logic.
