　　Lattice’s ECP5-5G family is the only FPGA product line supporting 5G SERDES and up to 85K LUTs in a small 10x10 mm package. The ECP5-5G devices support multiple 5G protocols including PCI Express Gen 2.0, CPRI, and JESD204B. This product family enables seamless connectivity to ASICs and ASSPs in a wide array of applications including cameras, displays, gaming platforms, small cells and low-end routers. Numerous resources including software, device samples, soft IP and hardware boards are available upon request.

　　Designers of equipment for many emerging high volumeapplications are blending FPGAs with ASICs and ASSPs torapidly build flexible systems that meet tight cost, power and formfactor constraints. In developing the ECP5TM FPGA family, Latticebreaks the rule that all FPGAs should be the highest density,power hungry, and expensive. With a focus on compact, highvolume applications, Lattice optimized the ECP5 architecture forlow cost, small form factor and low power consumption. Thesecharacteristics make the ECP5/ECP5-5G devices ideal fordelivering programmable connectivity solutions to complementASICs and ASSPs.

　　With up to 85K LUTs, 3.7Mbits embedded memory, 156 sysDSP blocks with DDR support, four 3.2Gbps/5Gbps SERDES channelsand 365 user IO, the ECP5/ECP5-5G devices provide a low-cost solution that meets the common connectivity requirements forcomplementing ASICs and ASSPs. A broad range of interface standards are supported including DDR3, LPDDR3, XGMII and7:1 LVDS, PCI Express, Ethernet (XAUI, GbE, SGMII) and CPRI. The devices are offered in multiple package options, and alsoinclude support for encryption and dual boot capabilities. Smart depopulation of balls simplifies PCB board routing and reducescost by utilizing fewer layers. Low power enhancements include stand-by mode operation of the individual blocks including SERDES,dynamic IO bank controllers and reduced operating voltage. The ECP5 family is supported by the Lattice DiamondTM designsoftware, the leading-edge design and implementation tool optimized for cost sensitive, low-power Lattice FPGA architectures.
