OR2T04A2T100-DB

The OR2T04A2T100-DB is an ORCA™2 field programmable gate array (FPGA) from Lattice Semiconductor Corporation. It provides a compact, reprogrammable logic fabric with 400 logic elements, 6,400 bits of on‑chip RAM and 77 general-purpose I/Os, packaged for surface-mount deployment.

Designed for commercial-grade embedded designs, this FPGA targets applications that require moderate logic density, flexible I/O count and a standard 100-pin LQFP/TQFP footprint with a 3.0–3.6 V supply and 0 °C to 70 °C operating range.

Key Features

• Core Logic Approximately 400 logic elements and an estimated 11,000-gate equivalent capacity provide reconfigurable digital logic resources for custom functions and glue logic.
• Configurable Logic Blocks Architecture organized to support up to 100 logic blocks (as listed) enabling partitioned logic and modular design approaches.
• Embedded Memory 6,400 bits of on-chip RAM for small data buffering, state storage and lookup-table needs within the programmable fabric.
• I/O Density 77 I/O pins for flexible interfacing, supporting multiple external peripherals and signal domains from a single device.
• Power and Supply Operates from a 3.0 V to 3.6 V supply range suitable for common commercial power rails.
• Package and Mounting Surface-mount 100-pin LQFP package (supplier lists 100-TQFP 14×14) for standard PCB assembly processes and compact board-level integration.
• Commercial Temperature Grade Specified for 0 °C to 70 °C operation to match general commercial electronic product environments.
• Regulatory Status RoHS compliant for lead-free assembly and regulatory alignment in commercial electronics.

Typical Applications

• Embedded control and glue logic — Use the programmable fabric and 77 I/Os to implement custom control functions and interface bridging in commercial electronic products.
• Prototype and development platforms — Compact logic capacity and on‑chip RAM make this FPGA suitable for early-stage digital prototypes and proof-of-concept designs.
• I/O expansion and peripheral interfacing — The device’s I/O count supports adding custom peripheral control or protocol bridging on space-constrained PCBs.
• User interface and keypad control — Implement control logic for panels, indicators and button matrices using the available logic elements and I/Os.

Unique Advantages

• Right-sized logic capacity: Approximately 400 logic elements balance capability and cost for many commercial embedded functions without unnecessary overhead.
• Integrated on-chip RAM: 6,400 bits of embedded memory reduce external component needs for small buffers and state storage.
• High I/O count in a compact package: 77 I/Os in a 100-pin LQFP/TQFP package enable broad interfacing while keeping board area modest.
• Standard power and temperature envelope: 3.0–3.6 V supply and 0 °C to 70 °C rating simplify integration into typical commercial systems.
• Surface-mount friendly: 100-pin LQFP (listed also as 100-TQFP 14×14) supports common SMT assembly and streamlined manufacturing.
• RoHS compliant: Meets lead-free requirements for modern commercial product assembly and supply-chain needs.
