ORCA 2 FPGA — logic density and I/O count for glue-logic consolidation
The Lattice OR2T26A7BA352-DB is an ORCA™2 family FPGA with 2304 logic elements and 63,600 usable gates — enough density to absorb a handful of 74-series glue-logic devices or a small state machine into a single programmable part. Its 384 user I/O pins, running on a 3 V supply rail, make it a fit for bus-interface or memory-controller applications where pin count matters more than on-chip memory depth (36 Kbit total RAM). The commercial junction temperature range (0°C to 70°C) limits deployment to indoor, temperature-controlled environments — not rated for industrial or automotive ambient extremes.
384 I/O in a 3 V FPGA — what the pin count buys you
With 384 I/O, this part can interface to a 32-bit address/data bus plus control signals and still have pins left for a handful of discrete status lines — useful in a processor-memory bridge or a multi-peripheral chip-select decoder. Surface-mount packaging (Bulk) means standard reflow assembly; no special handling beyond the MSL level typical for Lattice FPGAs of this era.
No official second-source or pin-compatible drop-in replacement exists from another manufacturer; if a BOM hedge is needed, a functional equivalent would require a board respin to a different package or supply voltage.
