• I/O Density  352 user I/O pins to support wide parallel interfaces and multiple device interconnects in a single package.
• Power Supply  Core voltage supported from 1.14 V to 1.26 V for standard LatticeECP operating conditions.
• Package & Mounting  484-ball BBGA package; supplier device package 484-FPBGA (23 × 23 mm). Surface-mount for PCB assembly.
• Operating Grade  Commercial temperature range of 0 °C to 85 °C.
• RoHS Compliance  RoHS-compliant lead-free device suitable for standard commercial manufacturing processes.
• Family-Level DSP & I/O Capabilities  LatticeECP family features include sysDSP support for high-performance multiply–accumulate operations, flexible programmable sysI/O buffers with broad interface support, dedicated DDR memory interface capability, and up to four analog PLLs for clock management.

Typical Applications

• Communication Interfaces  Implement parallel and serial protocol bridging, custom PHY interfaces, and I/O aggregation using the device’s high I/O count and flexible I/O buffers.
• Embedded Control  Use the FPGA fabric and on-chip RAM for motor control, system glue logic, and timing-critical control functions in commercial equipment.
• Signal Processing Acceleration  Leverage family DSP resources for medium-complexity multiply–accumulate tasks and data-path acceleration where dedicated DSP blocks are beneficial.
• Memory Interface and Buffering  Use on-chip RAM and the family’s dedicated DDR interface support for buffering and interfacing to external memory in cost-sensitive designs.

Unique Advantages

• Balanced Logic and Memory:  Approximately 15,400 logic elements and ~358 Kbits of on-chip RAM provide a practical balance for mid-range designs without over-provisioning.
• High I/O Count:  352 I/O pins reduce the need for external multiplexing and simplify board-level connectivity for complex interfaces.
• Compact BGA Footprint:  484-ball FPBGA (23 × 23 mm) delivers high pin density in a compact surface-mount package for space-constrained PCBs.
• Commercial-Grade Reliability:  Rated for 0 °C to 85 °C operation and RoHS-compliant construction for mainstream commercial deployments.
• Family-Level Peripheral Support:  Access to LatticeECP family features such as sysDSP blocks, flexible I/O standards, PLL clocking, and DDR interface support helps accelerate system-level design.
