Product details
Overview
ADSP-21065LKCAZ240 from Analog Devices is a 32-bit SHARC® floating-point DSP microcomputer optimized for real-time signal processing in audio, communications, and industrial control systems. It delivers 66 MIPS, 198 MFLOPS peak performance, features 544 Kbits of configurable dual-ported on-chip SRAM, and supports I²S with eight simultaneous transmit/receive channels. Its 240 MHz core clock (15 ns cycle time) enables sub-millisecond 1024-point FFT execution (0.274 ms).
For engineers reviewing the ADSP-21065LKCAZ240 datasheet, ADSP-21065LKCAZ240 pinout, ADSP-21065LKCAZ240 application, or ADSP-21065LKCAZ240 equivalent, key selection considerations include its 208-lead MQFP package, 3.3 V operation, SDRAM controller for glueless external memory interface, dual serial ports with TDM/I²S support, and code compatibility across the ADSP-2106x family.
Technical Context
The ADSP-21065LKCAZ240 implements the Super Harvard Architecture with four independent buses-two data (PM/DM), one instruction, and one I/O-enabling simultaneous dual-data fetch, instruction fetch, and I/O access per cycle. Its computation units (ALU, multiplier, barrel shifter) execute parallel single-cycle operations, including multiply-accumulate with extended 40-bit precision.
It integrates a 32-bit fixed-point and IEEE 32/40-bit floating-point execution unit, two hardware DAGs supporting up to 32 circular buffers, an on-chip instruction cache for looped filter/FFT acceleration, and a 10-channel DMA controller with dedicated serial and external port channels operating concurrently with full-speed core execution.

Equivalent & Alternatives
The following parts are listed as comparable options for similar DSP processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADSP-21060KBCZ-150 | 150 MHz core (20 ns cycle), 400 Kbits on-chip SRAM, no SDRAM controller, 225-ball BGA package | Limited memory bandwidth and external memory flexibility; suited for cost-constrained, lower-throughput control tasks | Select when SDRAM expansion is unnecessary and BGA layout is acceptable; not drop-in due to package and memory architecture differences |
| TMS320C6713BZDHA | 225 MHz C67x VLIW DSP, 256 Kbytes L2 RAM, EMIF for SDRAM/Flash, 208-pin HTQFP package | Different instruction set (VLIW vs. SHARC), no native I²S/TDM, requires external codec interface logic | Choose for TI ecosystem alignment or where C6000 toolchain familiarity outweighs SHARC's audio-specific peripherals |
Compared with ADSP-21065LKCAZ240, the ADSP-21060KBCZ-150 offers lower cost but sacrifices 33% peak performance and lacks SDRAM support, while the TMS320C6713BZDHA provides higher clock speed but requires additional interface components and software porting effort for audio-focused implementations.

FAQ
What is the maximum achievable data throughput for external memory transfers using the ADSP-21065LKCAZ240?
The ADSP-21065LKCAZ240 achieves up to 220 MB/s data transfer rate via its integrated SDRAM controller operating at 66 MHz. This is enabled by synchronous burst transfers and pipelined address/control signaling. The external port supports up to 264 MB/s DMA throughput for internal RAM ↔ external memory transfers, verified in benchmark testing under full-speed core execution conditions.
Does the ADSP-21065LKCAZ240 support booting from external flash memory?
Yes, the ADSP-21065LKCAZ240 supports booting from an 8-bit EPROM via the BSEL and BMS pins, or from external memory mapped at reset vector address. Boot source selection is controlled by hardwired BSEL/BMS states at power-up; no firmware configuration is required. The device does not natively support SPI or Quad-SPI flash boot modes without external glue logic.
How many independent serial communication channels does the ADSP-21065LKCAZ240 provide?
The ADSP-21065LKCAZ240 provides two fully independent synchronous serial ports (SPORT0 and SPORT1), each with primary and secondary transmit/receive pairs (DT0A/DR0A/DT0B/DR0B and DT1A/DR1A/DT1B/DR1B), enabling up to eight simultaneous I²S channels (four Tx + four Rx) or 32-channel TDM operation with programmable word length (3–32 bits) and frame sync.
Is the ADSP-21065LKCAZ240 pin-compatible with other ADSP-2106x family members?
No, the ADSP-21065LKCAZ240 is not pin-compatible with earlier ADSP-21060/21061/21062 variants due to differences in package type (208-MQFP vs. 240-BGA or 225-BGA), pin count, and signal assignment - though it is code- and function-compatible, allowing software reuse without hardware redesign.
What development tools are officially supported for the ADSP-21065LKCAZ240?
Analog Devices officially supports the ADSP-21065LKCAZ240 with VisualDSP++ IDE, SHARC Assembler, C compiler, cycle-accurate simulator, and EZ-ICE® In-Circuit Emulator. Third-party tools include Ada compilers, RTOS ports (e.g., VxWorks), and SHARCPAC™-compliant hardware modules. Debugging supports mixed C/assembly view, breakpoints, watchpoints, and memory profiling.
