OR2C15A4S304-DB

The OR2C15A4S304-DB is an ORCA™2 FPGA IC from Lattice Semiconductor Corporation. It provides reprogrammable logic in a compact 304-pin BFQFP package and is intended for commercial-temperature applications.

Key on-chip resources include 1,600 logic elements, approximately 25.6 kbits of embedded RAM, 256 user I/Os and an internal gate equivalent of 44,200, all powered from a 4.75 V to 5.25 V supply. The device is RoHS compliant and supplied in a surface-mount 304-pin package (304-SQFP, 40×40 mm footprint).

Key Features

• Core Logic  Provides 1,600 logic elements suitable for mid-range reconfigurable logic implementations and custom glue logic.
• Embedded Memory  Approximately 25,600 bits (≈25.6 kbits) of on-chip RAM for buffering, small FIFOs or lookup tables.
• I/O Density  256 user I/Os to support multiple parallel interfaces, GPIO banks, or bus connections directly from the device.
• Gate Equivalent  44,200 gates of equivalent logic capacity to help estimate integration level and replacement of discrete logic.
• Power and Supply  Single-supply operation from 4.75 V to 5.25 V simplifies integration with 5 V system domains.
• Package & Mounting  304-pin BFQFP (supplier package: 304-SQFP, 40×40 mm) in a surface-mount form factor for PCB-mounted designs.
• Operating Range & Grade  Commercial-grade device rated for operation from 0 °C to 70 °C.
• Environmental Compliance  RoHS compliant for lead-free manufacturing and assembly processes.

Typical Applications

• Custom logic and glue  Implement board-level glue logic, protocol adaptation, or custom finite-state machines using the device's 1,600 logic elements and gate capacity.
• I/O-intensive interface control  Use the 256 I/Os to implement parallel interfaces, front-panel I/O, or multi-signal bridging between subsystems.
• On-board buffering and small memory functions  Leverage approximately 25.6 kbits of embedded RAM for buffering, look-up tables, or small data stores.

Unique Advantages

• High I/O count: 256 I/Os enable dense interfacing without external I/O expanders, reducing BOM and PCB complexity.
• Balanced logic and memory: 1,600 logic elements paired with ~25.6 kbits of RAM provide a flexible resource mix for control and data-path functions.
• Standard 5 V supply compatibility: Operation from 4.75 V to 5.25 V simplifies integration into existing 5 V systems.
• Compact, surface-mount package: 304-pin BFQFP (40×40 mm) offers high pin count in a board-friendly form factor for space-constrained designs.
• Commercial temperature rating: Rated for 0 °C to 70 °C to match a wide range of commercial embedded applications.
• RoHS compliant: Supports lead-free assembly and modern environmental requirements.
