Logic density and I/O count — the BOM-fit decision
The LCMXO2-1200HC-4TG144C packs 1280 LUTs organised into 160 LABs — enough logic for a modest state machine, a few SPI/I2C bridges, or a glue-logic consolidation that would otherwise eat a handful of 74-series parts. The 107 user I/O in the 144-TQFP package is the highest-count variant in the -1200 LUT tier; the 100-pin sibling drops to 79 I/O, so this package is the choice when the bus width or parallel interface demands more than 80 pins.
On-chip RAM and supply rail — what the 65536 bits and 2.375-3.465 V range mean
65536 total RAM bits are distributed across the logic array as EBR blocks — enough for a 2 KB FIFO, a coefficient table, or a small register file without bolting on an external SRAM.
Active lifecycle and compliance — no end-of-life signal
ROHS3 Compliant with no exempt substances, covering EU RoHS and most global environmental regulations. The base product number is LCMXO2-1200, which spans multiple speed grades and packages; the -4 speed grade is the standard-cost option, while the -6 grade (LCMXO2-1200HC-6TG144C) offers faster timing for the same pinout and footprint.
