LFE2M20SE-5FN256C

LFE2M20SE-5FN256C is a Lattice MachXO2 non-volatile FPGA (LFE2 family). It packs about 20K logic elements into a compact 256‑pin FineLine BGA (FN256C) and uses the -5 speed grade. The device stores its configuration in on‑chip flash, enabling instant-on operation with no external configuration memory.
Key points:
- Non-volatile, flash-based FPGA for simple glue logic and small control/bridge tasks
- ~20K LEs in a 256-pin package; multiple I/O banks with various voltage standards
- Low power, suitable for cost- and space-constrained designs
- Programmable logic with embedded RAM blocks and basic clocking resources
Typical uses:
- Glue logic, small state machines, interface bridging, microcontroller peripherals
- Applications needing instant-on, compact footprints and easy field updates
Design flow and programming:
- Tooling: Lattice Diamond for synthesis/place-and-route; programming via SPI/JTAG per package
- Refer to the MachXO2 M20SE datasheet and product page for exact I/O counts, RAM capacity, timing, and electrical specs.
