Product details
Overview
ADSP-21062CS-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, two serial ports, and host processor interface - deployed in high-throughput communications infrastructure, radar signal processing, and real-time audio synthesis systems.
For engineers reviewing the ADSP-21062CS-160 datasheet, ADSP-21062CS-160 pinout, ADSP-21062CS-160 application, or ADSP-21062CS-160 equivalent, key selection considerations include sustained 80 MFLOPS performance, 240 MBps interprocessor link port bandwidth, 4-gigaword external address space, and compatibility with VisualDSP++ and CrossCore Embedded Studio toolchains.
Technical Context
The ADSP-21062CS-160 implements a Super Harvard Architecture with four independent buses enabling simultaneous instruction fetch, dual data operand access, and nonintrusive I/O - all within a single 25 ns cycle. Its core integrates parallel 32-bit ALU, multiplier, and shifter units supporting IEEE 32-bit single-precision and 40-bit extended-precision floating-point arithmetic.
Dual data address generators (DAG1/DAG2) provide hardware circular buffering for up to 32 buffers, while the on-chip instruction cache enables zero-overhead looping and full-speed FFT butterfly execution. The device supports glueless multiprocessing via distributed bus arbitration and broadcast writes across up to six nodes.

|---|---|
| Instruction Rate | 40 MHz / 25 ns cycle - enables single-cycle execution of multiply, ALU, and shifter operations. |
| Floating-Point Performance | 80 MFLOPS sustained - sufficient for real-time 1024-point complex FFT in 0.46 µs. |
| On-Chip SRAM | 2 Mbit dual-ported - configured as 64k × 32-bit data or 40k × 48-bit instructions; accessible concurrently by core and DMA. |

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-21060CS-160 | 4 Mbit on-chip SRAM, same 40 MHz core, identical pinout - larger memory footprint but higher power dissipation. | Better suited for monolithic FFT or large coefficient-table applications where 2 Mbit SRAM is insufficient. | Select ADSP-21060CS-160 when on-chip memory demand exceeds 2 Mbit and board layout accommodates identical MQFP_PQ4 footprint. |
| ADSP-21062KSZ-160 | PBGA package (225-ball), same electrical specs - improved thermal performance and higher I/O density, different pin mapping. | Preferred for space-constrained, high-density PCBs requiring enhanced thermal management in sealed enclosures. | Choose ADSP-21062KSZ-160 when thermal design margin is critical and redesign for PBGA routing is acceptable. |
Compared with ADSP-21062CS-160, the ADSP-21060CS-160 offers double on-chip memory at the cost of increased power draw, while the ADSP-21062KSZ-160 delivers identical functionality in a thermally superior PBGA package - both require careful evaluation of memory budget and thermal constraints in final system integration.

How much on-chip memory does the ADSP-21062CS-160 integrate, and what configurations are supported?
The ADSP-21062CS-160 integrates 2 Mbit of dual-ported SRAM, configurable as 64k × 32-bit data words, 40k × 48-bit instruction words, or mixed-width allocations up to the 2 Mbit limit. All configurations support concurrent core and DMA access - a capability confirmed in the ADSP-21062CS-160 datasheet Section "Memory and I/O Interface Features".
Can the ADSP-21062CS-160 interface directly with a 32-bit host microprocessor?
Yes, the ADSP-21062CS-160 provides a fully asynchronous 32-bit host processor interface with memory-mapped access to internal SRAM and IOP registers. Host read/write operations are supported at up to the ADSP-21062CS-160's full 40 MHz clock rate using HBR/HBG/REDY handshaking - as specified in the ADSP-21062CS-160 electrical characteristics table.
What packaging options are available for the ADSP-21062CS-160, and is it RoHS-compliant?
The ADSP-21062CS-160 is supplied exclusively in the 240-lead thermally enhanced MQFP_PQ4 package and is RoHS-compliant per Analog Devices' March 2013 Rev. H documentation.
