OR2T15B8S208-DB

Field Programmable Gate Array Overview

The OR2T15B8S208-DB is a Field Programmable Gate Array (FPGA) from the Lattice OR2TxxA/B family, manufactured using 0.3 µm CMOS technology. It features 784 logic cells and supports up to 480 user I/Os, which are 5 V tolerant for mixed-voltage interfacing. The device utilizes four 16-bit look-up tables per programmable function unit (PFU) to implement bus structures. Key electrical parameters include a maximum operating frequency (fMAX) of 360 MHz, propagation delay (tPD) of 3.0 ns, clock-to-output delay (tCO) of 2.9 ns, and setup time (tS) of 2.0 ns. It operates within a temperature range of -40 °C to 85 °C and requires 3.3 V or 3.3/5 V power supplies.

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'DB' against official Lattice documentation to confirm package type and temperature grade. Ensure compatibility with 3.3 V or 3.3/5 V supply rails as specified in the datasheet. Confirm RoHS status if required by your manufacturing standards, as some older OR2T variants may not be compliant. Cross-reference the PBGA256 footprint dimensions during PCB layout.

Field Programmable Gate Array Selection Notes

Select this component when 784 logic cells and high I/O density are required for 5 V tolerant applications. Compare against the OR2CxxA series if lower cost is prioritized over speed, noting the 0.35 µm process difference. Consider the OR2TxxB variant if higher performance grades are needed beyond the standard specifications provided for this model.

Field Programmable Gate Array Part Context

This part belongs to the Lattice OR2TxxA/B FPGA family, designed for high-performance interfacing and switching. It represents an evolution from the OR2CxxA series, utilizing a faster 0.3 µm CMOS process. The family is characterized by its ability to handle large bus structures and provide flexible I/O configurations for complex system integration tasks.

Field Programmable Gate Array Replacement Considerations

Direct replacements within the same family include other OR2TxxB variants with different cell counts or speed grades. Verify pinout compatibility before substituting with OR2TxxA models, as process node differences may affect timing characteristics.
