OR3T556BA256-DB

The OR3T556BA256-DB is a commercial-grade ORCA® Series 3T field programmable gate array (FPGA) offered in a 256‑BGA package. It delivers reconfigurable logic and flexible I/O for commercial embedded and digital designs where moderate logic capacity, plentiful I/O and on‑chip memory are required.

Based on the ORCA Series 3T architecture, this device supports fast LUT-based logic, robust routing and per-pin I/O configuration options, enabling mixed-signal interfacing and system glue logic in a single programmable device.

Key Features

• Logic Capacity  2,592 logic elements (cells) with a reported equivalent of 80,000 gates, suitable for medium-complexity logic functions and glue logic.
• Embedded Memory  43,008 bits of on-chip RAM—approximately 0.043 Mbits—supporting local storage and small data buffering.
• I/O Density & Flexibility  223 user I/Os provide extensive peripheral and bus connectivity. OR3T-series devices offer per-pin selectable I/O behavior including 5 V tolerance and pin-selectable I/O clamping diodes for 3.3 V or 5 V PCI compliance (series feature).
• ORCA 3T Architecture  Series 3T architecture with 0.3 µm process technology and LUT-based programmable function units, enabling mixed arithmetic and logic functions, fast-carry routing and hierarchical routing resources (series features).
• Package & Mounting  256‑BGA (supplier package: 256‑FPBGA 17×17) in a surface‑mount format for high I/O density in compact board layouts.
• Power & Voltage  Single-supply operation from 3.0 V to 3.6 V, simplifying power-rail planning for 3.3 V systems.
• Operating Range & Compliance  Commercial temperature grade with an operating range of 0 °C to 70 °C and RoHS compliance for environmental conformity.

Typical Applications

• Interface Bridging and Level Translation  Use the OR3T556BA256-DB to implement glue logic and protocol bridging between 3.3 V and 5 V domains, leveraging per-pin I/O configuration and series 5 V tolerance.
• Embedded Control & Custom Logic  Deploy as the central programmable logic element for control functions, state machines, and application-specific logic in commercial electronics.
• User Interface and Peripheral Management  High I/O count supports driving or monitoring numerous buttons, LEDs, sensors and peripheral buses in compact board designs.
• Prototyping and System Integration  Suitable for proof-of-concept and production-level implementations that require reconfigurable logic and moderate on-chip memory.

Unique Advantages

• High I/O Count: 223 user I/Os enable extensive external connectivity without additional interface chips, reducing BOM and board complexity.
• Moderate Logic & Memory Balance: 2,592 logic elements paired with ~0.043 Mbits of embedded RAM make it well-suited for medium-complexity designs that need local buffering and state storage.
• Flexible Voltage Support: 3.0 V–3.6 V supply wide enough for standard 3.3 V systems while OR3T-series I/O features support mixed-voltage interfacing.
• Compact, High‑Density Package: 256‑BGA (17×17 FPBGA) offers a small footprint with dense I/O, aiding space-constrained PCB layouts.
• RoHS Compliant: Environmentally compliant manufacturing helps meet regulatory and corporate sourcing requirements.
• Commercial Temperature Grade: Rated 0 °C to 70 °C for typical commercial applications and deployed environments.
