OR3T1256BC432-DB

The OR3T1256BC432-DB is an ORCA™3C Field Programmable Gate Array (FPGA) from Lattice Semiconductor Corporation. It delivers a balance of logic capacity, embedded RAM and I/O count in a compact 432-LBGA exposed pad package.

With 6,272 logic elements, 102,400 bits of on-chip RAM and 342 I/O, this FPGA is suitable for designs that require moderate logic density combined with substantial external connectivity, while operating from a 3.0–3.6 V supply range at commercial temperature grades.

Key Features

• Logic Capacity  6,272 logic elements providing the core programmable fabric for custom logic, state machines and glue logic.
• Embedded Memory  102,400 bits of on-chip RAM for buffering, small FIFOs and state storage.
• I/O Count  342 general-purpose I/O pins to support multiple external interfaces and dense connectivity requirements.
• Gate Count  186,000 gates enabling implementation of complex combinational and sequential functions.
• Package & Mounting  432-LBGA exposed pad package (supplier device package: 432-EBGA, 40×40) with surface-mount mounting for compact PCB integration.
• Power  Operates from a 3.0 V to 3.6 V supply range to match common system power rails.
• Temperature Grade  Commercial operating temperature range of 0 °C to 70 °C for typical commercial applications.
• Regulatory  RoHS compliant.

Typical Applications

• Embedded control and logic consolidation  Use the FPGA to implement custom control logic, protocol handling and glue logic where 6,272 logic elements and on-chip RAM are sufficient.
• High-density I/O systems  Designs that require large peripheral connectivity can take advantage of the 342 available I/O pins.
• Interface bridging and protocol adaptation  Implement protocol translation or interface aggregation functions using the available logic and memory resources.

Unique Advantages

• Balanced logic and memory  Combines 6,272 logic elements with 102,400 bits of RAM to support a range of mid-density FPGA designs without external memory for small buffers.
• High I/O availability  342 I/O pins simplify routing of multiple interfaces and reduce the need for external multiplexing components.
• Compact surface-mount package  The 432-LBGA exposed pad (40×40 EBGA) offers a space-efficient footprint for board-level integration.
• Simple power requirements  Single 3.0–3.6 V supply range aligns with common system power rails for straightforward power management.
• RoHS compliant  Environmentally compliant for standard commercial deployments.
