Overview

ADSP-21061KSZ-160 from Analog Devices is a 32-bit floating-point SHARC DSP microcomputer optimized for high-performance signal processing in communications, imaging, and graphics systems. It delivers 50 MIPS at 20 ns instruction cycle time, features dual-ported 1 Mbit on-chip SRAM, integrated serial ports (2×), host interface, DMA controller, and JTAG emulation - all in a 240-lead MQFP package rated for commercial temperature range.

For engineers reviewing the ADSP-21061KSZ-160 datasheet, ADSP-21061KSZ-160 pinout, ADSP-21061KSZ-160 application, or ADSP-21061KSZ-160 equivalent, key selection criteria include sustained 80 MFLOPS performance, IEEE 32-/40-bit floating-point support, dual-data-address-generator hardware circular buffering, zero-overhead looping, and multiprocessor interconnect capability up to six nodes.

Technical Context

The ADSP-21061KSZ-160 implements the Super Harvard Architecture with four independent buses enabling simultaneous instruction fetch, dual data fetch, and nonintrusive I/O - all in one 20 ns cycle. Its core integrates parallel ALU, multiplier, and shifter units supporting single-cycle IEEE 32-bit single-precision and 40-bit extended-precision floating-point operations.

Memory subsystem includes two dual-ported 0.5 Mbit SRAM blocks (total 1 Mbit), each independently accessible by core and I/O processor/DMA in single cycle. The external port provides unified 4-gigaword address space with programmable wait states, bank-select decoding, and glueless interfacing to DRAM, EPROM, and peripherals.

FAQ

What is the maximum operating frequency of the ADSP-21061KSZ-160?

The ADSP-21061KSZ-160 operates at a maximum clock frequency of 160 MHz, delivering 50 MIPS instruction throughput and 80 MFLOPS sustained floating-point performance. This speed grade is confirmed in the Analog Devices Rev. D datasheet under "ADSP-21061 Specifications" and corresponds to the -160 speed suffix. The device achieves this using a 5 V supply and is rated for commercial temperature range (0°C to +70°C).

Does the ADSP-21061KSZ-160 support IEEE 754 floating-point formats?

Yes, the ADSP-21061KSZ-160 supports IEEE 32-bit single-precision and 40-bit extended-precision floating-point data formats, as explicitly stated in the "KEY FEATURES-PROCESSOR CORE" section of the Rev. D datasheet. It also supports 32-bit fixed-point arithmetic. The 40-bit extended format provides guard bits to minimize round-off error accumulation in iterative algorithms like FFTs and IIR filters - a key advantage over standard 32-bit implementations.

What package type and lead count does the ADSP-21061KSZ-160 use?

The ADSP-21061KSZ-160 uses a 240-lead thermally enhanced MQFP (Metric Quad Flat Package) with an exposed thermal pad, as specified in the "Ordering Guide" and "Outline Dimensions" sections of the Rev. D datasheet. The "KSZ" in the part number denotes this MQFP variant. It is Pb-free and rated for commercial temperature operation, distinguishing it from the 225-ball PBGA option (e.g., ADSP-21061SBZ-160).

How many serial ports does the ADSP-21061KSZ-160 include, and what are their capabilities?

The ADSP-21061KSZ-160 includes two fully independent synchronous serial ports (SPORT0 and SPORT1). Each supports TDM multichannel mode, μ-law/A-law companding, keyword detection, and programmable word lengths from 3 to 32 bits. With frame sync and clock signals generated internally or externally, each port achieves up to 50 Mbps data rate - sufficient for 32-channel, 24-bit, 48 kHz audio streams or high-speed sensor data acquisition.

Is the ADSP-21061KSZ-160 pin-compatible with other SHARC processors?

Yes, the ADSP-21061KSZ-160 is pin-compatible with the ADSP-21060 and ADSP-21062 in the same 240-lead MQFP package, as confirmed in the "PORTING CODE FROM THE ADSP-21060 OR ADSP-21062" section of the Rev. D datasheet. However, link port pins present on the ADSP-21060/ADSP-21062 are designated as no-connects on the ADSP-21061KSZ-160, and memory column depth differs (8 vs. 16 columns per bank), requiring minor software adaptation for memory mapping.
