Key Features

• Core Logic  48,000 logic elements provide substantial programmable capacity for glue logic, protocol bridging, and custom state machines.
• Embedded Memory  Approximately 0.396 Mbits (396,288 bits) of on-chip RAM for data buffering, FIFOs, and small lookup tables.
• I/O Capability  339 user I/O pins to support wide parallel interfaces, multiple serial lanes, and flexible connectivity options.
• Package  484-BBGA (Supplier device package: 484-FPBGA, 23×23) offering a compact surface-mount footprint for space-constrained PCBs.
• Power  Core supply range of 1.14 V to 1.26 V to match system power-rail designs.
• Temperature and Grade  Commercial grade operation with an operating temperature range of 0 °C to 85 °C.
• Assembly  Surface mount package for standard SMT assembly flow.
• Compliance  RoHS compliant, meeting common lead-free materials requirements.

Typical Applications

• Embedded Systems  Implement custom control logic, protocol adaptation, or peripheral aggregation using the device’s 48,000 logic elements and abundant I/O.
• Interface Bridging  Use the 339 I/O pins and on-chip RAM to bridge between high-pin-count parallel buses or multiple serial interfaces.
• Prototyping and Development  A programmable FPGA fabric with substantial logic and memory density for early-stage system validation and feature iteration.
• Space-Constrained Designs  The 484-ball BGA (23×23) package enables high-density integration on compact PCBs while retaining significant I/O and logic resources.

Unique Advantages

• High Logic Density:  48,000 logic elements enable complex designs without external glue logic, reducing BOM and board complexity.
• Generous I/O Count:  339 user I/Os support multiple parallel interfaces or a mix of interfaces without external multiplexing.
