• I/O Density  400 user I/Os in the 672-BBGA package to support complex board-level connectivity and multiple external interfaces.
• Package & Mounting  672-ball FPBGA (27 × 27 mm) package, surface-mount mounting for compact board integration.
• Power  Low-voltage core operation with a supply range of 1.14 V to 1.26 V to match system power budgets requiring 1.2 V-class cores.
• Temperature & Grade  Commercial grade operation, specified from 0 °C to 85 °C.
• Family-Level DSP Capability  As a member of the LatticeECP family, the platform provides sysDSP blocks (family-level support of 4–8 blocks depending on device) for high-performance multiply–accumulate operations.
• Memory Interface Support  Family-level dedicated DDR memory interface support implementing up to DDR400 (200 MHz) for external memory subsystems.
• Clocking & System Support  Family-level support for up to four analog PLLs per device and system-level features including IEEE 1149.1 boundary scan and SPI boot flash interface.
• Standards-Compatible I/O  The LatticeECP family supports a wide range of I/O standards (LVCMOS, LVTTL, SSTL, HSTL, PCI, LVDS, LVPECL, RSDS and others), enabling flexible interface choices for mixed-signal systems.
• Regulatory  RoHS compliant.

Typical Applications

• Mainstream FPGA Systems  Mid-range logic and control implementations where a balance of logic elements and on-chip memory is required.
• Cost-Sensitive Embedded Designs  Systems that require optimized FPGA features and a compact BGA package to reduce BOM and board area.
• DSP Acceleration  Signal-processing functions leveraging the family’s sysDSP blocks for multiply–accumulate workloads.
• Memory Interface Controllers  Applications requiring dedicated DDR memory support up to DDR400 for external memory subsystems.

Unique Advantages

• Balanced Logic and Memory:  About 19,700 logic elements combined with roughly 434,176 bits of embedded RAM provide a substantial on-chip resource mix for medium-complexity designs.
• High I/O Count in Compact Package:  400 user I/Os in a 27 × 27 mm 672-BBGA package enable dense connectivity without a large package footprint.
• Low-Voltage Core:  1.14 V–1.26 V supply aligns with 1.2 V-class power domains commonly used in modern systems.
• DDR Memory Support:  Family-level dedicated DDR interface to support external memory at DDR400 rates, simplifying system memory integration.
• System Integration Features:  Multiple PLLs, boundary-scan and SPI boot support facilitate system-level design, debug and board bring-up.
• RoHS Compliance:  Meets environmental regulations for lead-free assembly and compliant product stacks.
