ADSP-21062LABZ-160

Digital Signal Processor Dsp Overview

The ADSP-21062LABZ-160 is a 32-bit floating-point digital signal processor from the Analog Devices SHARC family. It operates at a clock rate of 40 MHz, delivering 120 MFLOPS peak performance with a 25 ns instruction cycle time. The device integrates 2 Mbits of dual-ported on-chip SRAM and features an enhanced Super Harvard architecture with four independent buses for simultaneous data fetch and instruction execution. Key peripherals include a host processor interface, ten DMA channels, two synchronous serial ports, and six link ports. It is housed in a 225-ball plastic ball grid array (PBGA) package.

Digital Signal Processor Dsp Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as packaging variants may differ. Check for End-of-Life (EOL) notifications or Product Change Notifications (PCN) prior to procurement, as this series has undergone manufacturing transitions.

Digital Signal Processor Dsp Selection Notes

Select the ADSP-21062LABZ-160 when 2 Mbits of on-chip memory suffices for the application; choose the ADSP-21060 variant for 4 Mbits. Ensure the design supports 3.3V logic levels, as the 'L' suffix denotes low-voltage operation. Verify that the 225-ball PBGA package footprint aligns with the PCB layout constraints.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2106x SHARC family, which includes the ADSP-21060, ADSP-21062, and their low-voltage (L) counterparts. The 'LABZ' suffix indicates the 3.3V version in the 225-ball PBGA package. It shares architectural compatibility with other SHARC processors but differs in memory capacity and operating voltage compared to the standard 5V ADSP-21062.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-compatible replacements within the same package are limited due to EOL status. Consider the ADSP-21062LCB-133 for similar functionality if voltage and speed requirements allow, though it is also discontinued. Modern alternatives require architectural migration.
