Product details
Overview
AD14160LKB-4 from Analog Devices is a quad-core SHARC® DSP multiprocessor module integrating four ADSP-21060 floating-point processors in a single 452-ball CBGA package, delivering 480 MFLOPS peak performance, 16 Mbit shared on-module SRAM, and full 48-bit address/data external bus connectivity for high-density signal processing systems in radar, medical imaging, and real-time audio synthesis.
For engineers reviewing the AD14160LKB-4 datasheet, AD14160LKB-4 pinout, AD14160LKB-4 application, or AD14160LKB-4 equivalent, key selection considerations include its 25 ns instruction cycle time, 40 Mbyte/s per link port bandwidth (640 Mbyte/s total), IEEE 754 32-/40-bit floating-point support, JTAG 1149.1 debug interface, and shared-memory multiprocessing architecture with rotating/fixed bus arbitration.
Technical Context
The AD14160LKB-4 implements a ring-connected quad-SHARC topology with internal link ports (LINK 0–5 per core) and externally exposed link/serial I/O-16 total link ports (4 per SHARC) and 8 serial ports (2 per SHARC). Each SHARC core executes instructions in 25 ns with parallel ALU/multiplier/shifter units and dual DAGs supporting up to 32 hardware circular buffers.
It features unified 4-gigaword address space spanning internal memory (16 Mbit shared SRAM), per-core 4 Mbit SRAM blocks, and off-module expansion via 48-bit data/32-bit address external bus with programmable wait states, DRAM page-mode support (PAGE signal), and MS3–0 bank selects. Bus arbitration uses RPBA-configurable rotating or fixed priority across BR1–BR6 lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Count | Four independent ADSP-21060 SHARC DSP cores sharing 16 Mbit SRAM and external bus resources. |
| Peak Performance | 480 MFLOPS - achieved via simultaneous execution across four 25 ns-cycle floating-point cores. |
| On-Module Memory | 16 Mbit shared SRAM - accessible by all four SHARCs via unified address space without external glue logic. |
| External Bus Width | 48-bit data / 32-bit address - supports 4-gigaword off-module memory mapping with MS3–0 bank decoding. |
| Link Port Bandwidth | 640 Mbyte/s total - 16 independently configurable 4-bit link ports (4 per SHARC), each up to 40 Mbyte/s in 2× mode. |
| Serial Port Count | Eight 40 Mbit/s serial ports - two per SHARC, supporting TDM, µ-law/A-law companding, and big/little-endian framing. |
| JTAG Interface | IEEE 1149.1 compliant - enables non-intrusive in-circuit emulation, boundary scan, and real-time register/memory access. |
Pinout & Package
Package: 452-ball Ceramic Ball Grid Array (CBGA), 47 mm × 47 mm body, 0.050" ball pitch, 0.200" max height, thermal resistance uJC = 0.368°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ADDR31–0 | External bus address lines | Common to all four SHARCs; outputs valid addresses during master cycles, inputs during slave accesses; enables unified 4-gigaword addressing. |
| DATA47–0 | External bus data lines | Tri-state bidirectional bus carrying 32-bit FP, 40-bit extended FP, or 16-bit short-word data; supports PROM boot (bits 23–16). |
| MS3–0 | Memory select outputs | Chip-select signals for external memory banks; decoded from address bits and active during conditional memory instructions regardless of condition outcome. |
| RD / WR | Read/write strobes | Active-low control signals asserted by bus master; used for synchronous external memory/peripheral access and inter-SHARC internal memory reads/writes. |
| PAGE / ADRCLK / SW | DRAM timing & sync controls | PAGE signals DRAM page boundary crossing (Bank 0 only); ADRCLK provides clock reference for address setup; SW enables early write indication for synchronous memory abort handling. |
| ACK | Memory acknowledge | Input/output with keeper latch; deasserted by peripherals or slave SHARCs to insert wait states; maintains level during bus transitions. |
Key Features
| Feature | Design Value |
|---|---|
| Quad-SHARC Ring Interconnect | Internal LINK 0–5 connections form low-latency ring topology enabling direct inter-core communication without external routing. |
| Rotating/Fixed Bus Arbitration | RPBA pin selects arbitration mode; rotating priority minimizes starvation in dynamic workloads; fixed priority ensures deterministic latency for real-time tasks. |
| Broadcast Write Capability | Single write to multi-processor memory space simultaneously updates identical registers across all four SHARCs - ideal for reflective semaphore initialization. |
| CPA Mode Support | Core Priority Access allows slave SHARC core memory accesses to preempt ongoing DMA transfers - critical for low-latency interrupt response. |
| Link Port Booting | LINK 4 dedicated for boot loading; supports daisy-chain or parallel common connection - enables flexible multiprocessor firmware distribution from single source. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-DSP multiprocessor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD14160LKB-3 | Same quad-SHARC architecture and pinout, but rated for 3.3 V operation only (vs. 5 V/3.3 V dual supply in AD14160LKB-4). | Requires separate 3.3 V power domain; not suitable for legacy 5 V system integration or mixed-voltage backplanes. | Select AD14160LKB-3 only when board-level power design is fully 3.3 V and no 5 V peripherals interface directly to the module. |
| AD14160LKB-5 | Identical functionality and package, but qualified for extended temperature range (–40°C to +85°C) versus commercial grade (0°C to +70°C) of AD14160LKB-4. | Required for industrial or outdoor deployments where ambient temperature exceeds 70°C or drops below 0°C. | Choose AD14160LKB-5 when operating environment exceeds commercial temperature limits; otherwise AD14160LKB-4 offers cost advantage. |
Compared with AD14160LKB-3 and AD14160LKB-5, the AD14160LKB-4 provides dual-voltage flexibility for hybrid system integration and commercial-grade thermal performance optimized for cost-sensitive embedded signal processing platforms where extended temperature qualification is unnecessary.

FAQ
What is the difference between AD14160LKB-4 and AD14160LKB-3?
The AD14160LKB-4 supports both 5 V and 3.3 V operation, while AD14160LKB-3 is 3.3 V only. This makes AD14160LKB-4 compatible with legacy 5 V logic interfaces and mixed-supply systems. Both share identical pinout, performance specs, and CBGA packaging. The AD14160LKB-4 datasheet confirms dual-voltage capability in its "5 V and 3.3 V Operation" feature list.
Does AD14160LKB-4 support JTAG debugging?
Yes, AD14160LKB-4 includes full IEEE 1149.1 JTAG Test Access Port (TAP) with TCK, TMS, TDI, TDO, and TRST pins. It enables non-intrusive in-circuit emulation, boundary scan testing, and real-time memory/register access using Analog Devices EZ-ICE emulators. The AD14160LKB-4 functional block diagram explicitly labels JTAG as a core feature.
How is memory shared among the four SHARCs in AD14160LKB-4?
AD14160LKB-4 provides 16 Mbit of on-module SRAM shared across all four SHARCs via a unified 4-gigaword address space. Each SHARC can directly read/write other SHARCs' internal memory and IOP registers using multi-processor memory map addresses (e.g., ID=001 for SHARC_A). The shared bus (48 data, 32 address) is brought off-module for expansion.
Can AD14160LKB-4 boot from external memory without EPROM or host processor?
Yes, AD14160LKB-4 supports "no-boot" mode where SHARC_A begins execution from address 0x00400004 in external memory after reset. Other SHARCs (B/C/D) can be configured for no-boot or host booting. This requires external memory to be preloaded and accessible at power-up, with proper MS3–0 and WAIT register configuration.
What is the maximum link port bandwidth achievable with AD14160LKB-4?
AD14160LKB-4 delivers up to 640 Mbyte/s total link port bandwidth: 16 independent 4-bit link ports (4 per SHARC), each configurable for 1× (4-bit) or 2× (8-bit) operation at up to 40 Mbyte/s. Internal ring interconnect uses LINK 0–5; remaining links (e.g., LINK 1–4 per SHARC) are exposed for off-module I/O.
