ADSP-21065LCCA-240

Digital Signal Processor Dsp Overview

The ADSP-21065LCCA-240 is a 32-bit floating-point digital signal processor from the SHARC family, manufactured by Analog Devices Inc. It operates at a clock rate of 60 MHz with a peak performance of 198 MFLOPS and 66 MIPS. The device features 544 Kbits of on-chip dual-ported SRAM and supports IEEE 32-bit and 40-bit floating-point arithmetic alongside 32-bit fixed-point operations. It utilizes a Super Harvard Architecture with four independent buses for single-cycle instruction and data fetches. The component is housed in a 196-ball CSPBGA package (15x15 mm) and functions within a temperature range of -40°C to 100°C.

Digital Signal Processor Dsp Feature Summary

• Super Harvard Architecture enabling simultaneous fetch of one instruction and two operands per cycle via four independent buses.
• Integrated 544 Kbits dual-ported SRAM configurable for various word sizes (16-, 32-, or 48-bit).
• On-chip SDRAM controller providing glueless interface to external memory at up to 66 MHz.
• Ten DMA channels: eight dedicated to serial ports and two to the external port for zero-overhead data transfers.

Digital Signal Processor Dsp Applications

• Communications systems requiring high-throughput signal processing.
• Audio processing applications utilizing I2S support for multiple channels.
• Automotive instrumentation and control systems.
• Industrial automation and data acquisition platforms.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix '-240' against the manufacturer's current datasheet to confirm the exact clock frequency rating and temperature grade. Confirm that the 196-CSPBGA package dimensions match the target PCB footprint requirements. Check for end-of-life status as this model may be discontinued or superseded by newer revisions in the SHARC family.

Digital Signal Processor Dsp Selection Notes

Select this component when a code-compatible upgrade from the ADSP-2106x family is required with integrated SDRAM control. Ensure the design accommodates the 3.3V core and I/O voltage levels. Verify that the 196-ball BGA package is suitable for the manufacturing capabilities, as it requires specialized surface mount technology compared to leaded packages.

Digital Signal Processor Dsp Part Context

This part belongs to the ADSP-21065L series, which is code-compatible with the broader ADSP-21060/21061/21062 family. It represents a cost-sensitive member of the SHARC processor line, designed to offer high performance without compromising precision. The 'CCA' designation typically refers to the commercial temperature range and CSPBGA packaging variant within the product line.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-to-pin replacements are not explicitly listed in the provided documentation. Consider the ADSP-21065LKCA-264 for similar functionality with a potentially different clock speed or package configuration, though verification of electrical compatibility is required. Review the ADSP-21375 migration guide for advanced feature sets if higher performance is needed.
