Product details

ORCA 3C logic density and I/O budget

The OR3T1256BC432-DB packs 6272 logic cells and 186000 gates — enough for medium-complexity glue logic, state machines, or a soft-core processor with peripheral decode. The 342 I/O count gives you headroom for a wide memory bus plus parallel control lines without multiplexing. On-chip block RAM totals 102400 bits, suitable for a couple of 8-bit FIFOs or a small line buffer in a video-timing application. The 3V supply rail keeps core and I/O on a single 3.3V plane, simplifying the board power tree.

It belongs in an office switch, a test-equipment controller, or a lab instrument, not on a factory floor or under a vehicle hood.

Lattice lists the OR3T1256BC432-DB as Active. You can design it in today and expect supply for the foreseeable future.

Frequently asked questions

How does OR3T1256BC432-DB compare to the OR3T1256BC600-DB?

Both are ORCA 3C devices with identical gate count (186000), RAM (102400 bits), and logic cells (6272). The BC600 variant offers 448 I/O versus 342 I/O on the BC432. If your board needs the extra I/O lanes, the BC600 is the functional step-up; otherwise the BC432 saves package real estate.
