Logic capacity and I/O count — what 24K LEs and 197 I/O mean for a design
The LFE5U-25F-6BG256I is a Lattice ECP5 FPGA with 24000 logic elements arranged across 6000 LABs/CLBs, plus 1032192 total block RAM bits (about 1 Mbit). The 197 user I/O are available on the 256-ball CABGA package — enough for a moderate-density glue-logic or interface design without bumping into the I/O ceiling.
Supply voltage and temperature — the operating envelope
Core supply is 1.045 V to 1.155 V — a tight 110 mV window that demands a well-regulated rail, not a generic 1.2 V LDO.
Package and board-fit — 256-CABGA 14x14 mm
The 256-ball CABGA measures 14x14 mm with a 0.80 mm ball pitch — a standard BGA footprint that routes out on four layers without microvias. The supplier device package is 256-CABGA (14x14), and the mounting is surface-mount only.
Lifecycle and compliance — active production, RoHS3 confirmed
Lattice lists the LFE5U-25F-6BG256I as Active — no NRND flag, no last-time-buy notice.
