Product details
Overview
AD14160KB-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 AD14160KB-4 datasheet, AD14160KB-4 pinout, AD14160KB-4 application, or AD14160KB-4 equivalent, key selection criteria include its 4× ADSP-21060 core architecture, 40 Mbyte/s per link port bandwidth, IEEE 754 32/40-bit floating-point support, JTAG 1149.1 debug interface, and shared-bus multiprocessing capability with rotating/fixed priority arbitration.
Technical Context
The AD14160KB-4 implements a ring-connected quad-SHARC topology with six 4-bit link ports per core (16 total off-module), eight 40 Mbit/s serial ports, and a unified 4-gigaword address space enabling direct interprocessor memory access across all four SHARCs. Each core executes instructions at 25 ns with three-bus Harvard architecture supporting simultaneous instruction fetch and dual operand reads.
Bus arbitration uses BR1–BR6 request lines with RPBA-selectable rotating or fixed priority schemes; CPA mode enables core-initiated external bus access to override ongoing DMA transfers. Booting supports EPROM, host, link port, or no-boot modes with independent control for SHARC_A versus SHARCs B–D.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-DSP multiprocessor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD14160L | Same quad-SHARC architecture but rated for industrial temperature range (−40°C to +85°C); AD14160KB-4 is commercial grade (0°C to +70°C) | Preferred for extended-temperature deployments such as outdoor radar or vehicle-mounted systems | Select AD14160L when operating outside 0°C–70°C ambient or requiring extended reliability validation |
| ADSP-TS201S | Single-core TigerSHARC processor with 600 MFLOPS peak, 24 Mbit on-chip SRAM, and 250 MHz clock - no integrated quad-cluster or shared bus | Suitable for higher-clock-rate single-thread workloads but requires external interconnect for multi-processor scaling | Choose ADSP-TS201S when prioritizing raw single-core throughput over integrated multiprocessing density |
Compared with AD14160KB-4, AD14160L offers identical functionality with extended thermal qualification, while ADSP-TS201S trades integrated quad-core coherence for higher per-core speed and larger on-die memory - making it better suited for applications where inter-core communication overhead dominates versus raw computational density.

FAQ
What is the operating temperature range for the AD14160KB-4?
The AD14160KB-4 is specified for commercial temperature operation from 0°C to +70°C ambient. It uses a ceramic ball grid array package with thermal resistance uJC = 0.368°C/W, and requires proper PCB thermal vias and heatsinking for sustained 480 MFLOPS operation. For extended temperature applications, the AD14160L variant supports −40°C to +85°C.
How does the AD14160KB-4 handle interprocessor communication between its four SHARC cores?
The AD14160KB-4 implements a ring-connected topology using two link ports per SHARC core, enabling deterministic low-latency communication. Each core also accesses the others' internal memory directly via the unified 4-gigaword address space, using MSRG message registers and VIRPT vector interrupts for hardware-accelerated synchronization and resource sharing without software polling.
Can the AD14160KB-4 boot independently without an external host or EPROM?
Yes - the AD14160KB-4 supports "no-boot" mode where SHARC_A begins execution from address 0x00400004 in external memory after reset. SHARCs B–D can be configured identically or set to host-boot mode for controlled initialization. This mode requires pre-loaded code in off-module memory and proper MS3–0 bank configuration via SYSCON register.
What is the maximum data rate supported by the serial ports on the AD14160KB-4?
All eight serial ports on the AD14160KB-4 operate at up to 40 Mbit/s each, synchronized to the module's internal clock. Each port supports programmable word length (3–32 bits), TDM multi-channel mode, µ-law/A-law companding, and independent transmit/receive DMA channels - enabling direct connection to high-speed ADCs, DACs, or CODECs without glue logic.
Does the AD14160KB-4 include on-board bypass capacitance?
Yes - the AD14160KB-4 integrates 14 on-module 0.1 µF bypass capacitors. Analog Devices recommends placing at least four additional 0.018 µF capacitors near the module corners on the target PCB to ensure stable power delivery across all four SHARC cores during peak 480 MFLOPS operation and minimize high-frequency noise coupling.
