Analog Devices Inc. ADSP-21062LKS-160

Overview

ADSP-21062LKS-160 from Analog Devices is a 32-bit floating-point SHARC® digital signal processor with 2 Mbit dual-ported on-chip SRAM, 40 MHz instruction rate (25 ns cycle), and 3.3 V core operation. It integrates dual serial ports, six link ports, host interface, DMA controller, and JTAG emulation for real-time signal processing in communications infrastructure and audio systems.

For engineers reviewing the ADSP-21062LKS-160 datasheet, ADSP-21062LKS-160 pinout, ADSP-21062LKS-160 application, or ADSP-21062LKS-160 equivalent, key selection criteria include on-chip memory size, 3.3 V supply compatibility, 240-pin MQFP_PQ4 package footprint, and support for glueless multiprocessing via link/parallel bus interfaces.

Technical Context

The ADSP-21062LKS-160 implements the Super Harvard Architecture with four independent buses enabling simultaneous instruction fetch, dual data operand access, and nonintrusive I/O. Its computation units-ALU, multiplier, and shifter-execute single-cycle IEEE 32-bit floating-point or 40-bit extended-precision operations.

Dual data address generators (DAG1/DAG2) provide hardware circular buffering and bit-reverse addressing essential for FFT and filter implementations. The on-chip instruction cache enables three-bus operation (instruction + two operands) per cycle, sustaining 80 MFLOPS while supporting zero-overhead looping and parallel multiply-accumulate instructions.

FAQ

What is the maximum operating frequency of the ADSP-21062LKS-160?

The ADSP-21062LKS-160 operates at a maximum instruction rate of 40 MHz with a 25 ns instruction cycle time. This frequency is supported under specified 3.3 V supply and ambient temperature conditions per Analog Devices Rev. H datasheet Section "ADSP-21060L/ADSP-21062L Specifications". The device does not require an external PLL; CLKIN must be driven at exactly 40 MHz for full-speed operation.

Does the ADSP-21062LKS-160 support IEEE 754 single-precision floating-point arithmetic?

Yes, the ADSP-21062LKS-160 fully supports IEEE 32-bit single-precision floating-point format as part of its native computation units. Its ALU, multiplier, and shifter execute single-cycle IEEE-compliant operations, and the processor also supports 40-bit extended-precision and 32-bit fixed-point formats - all selectable per instruction without mode switching overhead.

How much on-chip memory does the ADSP-21062LKS-160 integrate, and is it dual-ported?

The ADSP-21062LKS-160 integrates 2 Mbit (256 kbytes) of on-chip SRAM organized as two 1 Mbit blocks, each dual-ported. This allows simultaneous, single-cycle access by the core processor and DMA controller or I/O processor - a key enabler for real-time streaming applications such as multi-channel audio or radar pulse processing without memory contention.

Can the ADSP-21062LKS-160 interface directly with a 32-bit microprocessor host?

Yes, the ADSP-21062LKS-160 includes a dedicated 32-bit host port accessible via its external bus interface. Using asynchronous handshake signals (HBR/HBG/REDY), a 32-bit host processor can directly read/write internal memory and IOP registers without additional logic. Four DMA channels are allocated to this interface, enabling high-throughput code/data transfers with minimal software overhead.

What package type and pin count does the ADSP-21062LKS-160 use?

The ADSP-21062LKS-160 uses a 240-lead thermally enhanced MQFP_PQ4 package with 0.5 mm lead pitch and an exposed thermal pad. This RoHS-compliant surface-mount package measures 27.2 mm × 27.2 mm and is optimized for industrial thermal performance and manual or automated assembly - distinct from the PBGA variant ADSP-21062LKB-160.
