Replacement verdict
Compatible functional replacement candidate
The ADSP-21062CS-160 is a higher-speed member of the same ADSP-2106x SHARC family as the ADSP-21060, sharing the same core architecture, instruction set, memory organization, and package footprint. It can serve as a functional replacement candidate where the faster 160 MHz grade is acceptable, but the differing speed grade, on-chip SRAM configuration, and power/thermal profile must be validated against the target design before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | ADSP-21060 | ADSP-21062CS-160 | Why it matters |
|---|---|---|---|
| Core Clock / Instruction Rate | 40 MHz max (25 ns instruction cycle) | 40 MHz max (25 ns instruction cycle) | Determines peak DSP throughput; identical instruction rate means similar real-time processing capability. |
| On-Chip SRAM | 512 Kbit (4 Mbit total on-chip memory including 4 Mbit dual-ported SRAM) | 256 Kbit (2 Mbit on-chip SRAM) | Larger on-chip memory reduces external memory accesses and latency; the 21060 offers twice the SRAM of the 21062. |
| On-Chip Memory Configuration | 4 Mbit dual-ported SRAM (2 Mbit program + 2 Mbit data) | 2 Mbit dual-ported SRAM (1 Mbit program + 1 Mbit data) | Memory partitioning affects how much code and data can reside on-chip without external memory. |
| Package / Pin Count | 240-pin PQFP / 225-ball PBGA | 240-pin PQFP | Package and pinout must match the target PCB footprint for drop-in substitutability. |
| Operating Temperature Range | 0°C to +70°C (commercial) / -40°C to +85°C (industrial) | 0°C to +70°C (commercial) | Temperature grade determines suitability for industrial versus commercial environments. |
| Supply Voltage | 5.0 V ± 5% | 5.0 V ± 5% | Supply voltage compatibility is essential for direct board-level replacement. |
| External Memory Interface | Supports up to 4 Gwords external address space with host port and DMA | Supports external memory with host port and DMA | External memory addressing capability affects system scalability and design flexibility. |
| Serial Ports | 2 synchronous serial ports | 2 synchronous serial ports | Serial ports provide connectivity to codecs, ADCs, and other peripherals; matching count preserves I/O capability. |
| Link Ports | 6 link ports (8-bit) | 6 link ports (8-bit) | Link ports enable glueless multiprocessor clustering; identical count supports the same multiprocessor topologies. |
| DMA Channels | 10 DMA channels | 10 DMA channels | DMA channels offload data movement from the core; matching count preserves data throughput characteristics. |

Frequently asked questions
What are the key architectural differences between the ADSP-21060 and the ADSP-21062CS-160?
Both devices are members of the Analog Devices SHARC (Super Harvard Architecture Computer) family and share the same core architecture, including a 32-bit floating-point DSP core, dual-ported on-chip SRAM, and a 48-bit instruction word. The ADSP-21060 is the base SHARC device, while the ADSP-21062CS-160 is a speed-graded variant of the ADSP-21062 that operates at 160 MHz. The primary differences are operating frequency, on-chip memory size, and package/grade options rather than core architecture.
How do the on-chip memory sizes of the ADSP-21060 and ADSP-21062CS-160 compare?
The ADSP-21060 integrates 4 Mbit of on-chip dual-ported SRAM (2 Mbit program memory and 2 Mbit data memory). The ADSP-21062CS-160 integrates 2 Mbit of on-chip dual-ported SRAM (1 Mbit program memory and 1 Mbit data memory). Designers requiring larger on-chip memory should account for this difference when porting code between the two devices.
What is the maximum core clock frequency of the ADSP-21062CS-160 compared with the ADSP-21060?
The ADSP-21062CS-160 is specified for a 160 MHz core clock, which corresponds to a 6.25 ns instruction cycle. The ADSP-21060 is offered in lower speed grades (for example, 33 MHz, 40 MHz, and 60 MHz variants) and does not have a 160 MHz grade. The higher clock rate of the ADSP-21062CS-160 provides greater throughput for compute-intensive DSP algorithms.
Are the ADSP-21060 and ADSP-21062CS-160 pin-compatible?
No. The ADSP-21060 is available in a 240-lead MQFP package, while the ADSP-21062CS-160 is offered in a 240-lead MQFP package as well, but the two devices are not drop-in pin-compatible because of differences in on-chip memory configuration and signal definitions. A direct substitution requires verification against the respective datasheets and the target PCB layout.
Can the ADSP-21062CS-160 be used as a direct replacement for the ADSP-21060 in an existing design?
Not without validation. Although both are SHARC-family devices with a compatible core instruction set, the ADSP-21062CS-160 has half the on-chip SRAM of the ADSP-21060 and a different speed grade. Firmware that relies on the ADSP-21060's 4 Mbit of internal memory or its specific timing parameters must be re-verified, and the PCB must be checked for package and pinout compatibility before substitution.
What are the typical applications for the ADSP-21060 and ADSP-21062CS-160?
Both devices are 32-bit floating-point SHARC DSPs suited to audio processing, industrial control, instrumentation, and communications signal processing. The ADSP-21060, with its larger 4 Mbit on-chip SRAM, is often chosen where more internal buffering is needed, while the ADSP-21062CS-160 at 160 MHz is selected for higher-throughput applications that can operate within 2 Mbit of on-chip memory.
Do the ADSP-21060 and ADSP-21062CS-160 support the same external memory and link port interfaces?
Yes. Both devices provide a 32-bit external memory interface, two serial ports, and SHARC link ports for inter-processor communication, consistent with the SHARC family architecture. The number of available link ports and the external memory addressing range should be confirmed against the specific datasheet revision, as these details can vary by device variant.
What are the power supply requirements for the ADSP-21060 and ADSP-21062CS-160?
Both devices operate from a 3.3 V supply for the I/O and a core supply as specified in their respective datasheets. The ADSP-21062CS-160 at 160 MHz has higher dynamic power consumption than lower-speed ADSP-21060 grades, so thermal and power budgeting must be recalculated when comparing the two parts. Exact supply voltage tolerances and current ratings should be taken from the official Analog Devices datasheets.
