CrossLink-NX™ Field Programmable Gate Array (FPGA) IC 72 1548288 39000 121-VFBGA, CSPBGA

General Description

CrossLink™-NX family of low-power FPGAs can be used in a wide range of applications, and are optimized for bridging and

processing needs in Embedded Vision applications – supporting a variety of high bandwidth sensor and display interfaces,

video processing and machine learning inferencing. It is built on Lattice Nexus FPGA platform, using low-power 28 nm

FD-SOI technology. It combines the extreme flexibility of an FPGA with the low power and high reliability (due to extremely

low SER) of FD-SOI technology, and offers small footprint package options.

CrossLink-NX supports a variety of interfaces including MIPI D-PHY (CSI-2, DSI), LVDS, SLVS, subLVDS, PCI Express (Gen1,

Gen2), SGMII (Gigabit Ethernet), and more.

Processing features of CrossLink-NX include up to 39K Logic Cells, 56 18x18 multipliers, 2.9 Mb of embedded memory

(consisting of EBR and LRAM blocks), distributed memory, DRAM interfaces (supporting DDR3, DDR3L, LPDDR2, and

LPDDR3 up to 1066 Mbps x16 data width).

CrossLink-NX FPGAs support fast configuration of its reconfigurable SRAM-based logic fabric, and ultra-fast configuration

(in under 3 ms) of its programmable sysI/O™. Security features to secure user designs include bitstream encryption and

password protection. In addition to the high reliability inherent to FD-SOI technology (due to its extremely low SER), active

reliability features such as built-in frame-based SED/SEC (for SRAM-based logic fabric), and ECC (for EBR and LRAM) are

also supported. Built-in ADC is available in each device for system monitoring functions.

Lattice Radiant™ design software allows large complex user designs to be efficiently implemented on CrossLink-NX FPGA

family. Synthesis library support for CrossLink-NX devices is available for popular logic synthesis tools. Radiant tools use the

synthesis tool output along with constraints from its floor planning tools, to place and route the user design in

CrossLink-NX device. The tools extract timing from the routing, and back-annotate it into the design for timing verification.

Lattice provides many pre-engineered IP (Intellectual Property) modules for CrossLink-NX family. By using these

configurable soft IP cores as standardized blocks, you are free to concentrate on the unique aspects of your design,

increasing your productivity.
