Packaging

Type: FineLine BGA (F256), tray packing for BGAs

Manufacturer package code: 869, F256 family

Material: Lead-free balls and green molding compound (RoHS compliant, N option)

Approximate size and pitch: 256 balls, fine-pitch BGA (commonly 1.0 mm pitch, ~17 x 17 mm body; verify exact outline in the datasheet)

Pin configuration: 256-ball grid with multiple I/O banks, dedicated configuration pins, JTAG (TCK, TMS, TDI, TDO), dedicated clock pins, distributed power and ground balls

Moisture sensitivity: Typically MSL 3 for BGA devices; follow moisture handling per JEDEC and the datasheet

Reflow: Pb-free reflow capable (260°C peak per JEDEC; follow datasheet profile)

Thermal characteristics: Thermal performance depends on board design and airflow; see datasheet for thermal resistance (θJA/θJC) and recommended junction temperature limits

Electrical properties (high level):

- Core voltage (VCCINT) typically 2.5 V nominal

- I/O bank voltages commonly support 3.3 V and 2.5 V standards (check datasheet for all supported standards and any 1.8 V options)

- Configuration via JTAG and Passive Serial

- Speed grade -2 performance class

Date code on available stock: 20+ (contact us for lot details and traceability)

Lifecycle

Status: Mature and widely deployed, but part of a legacy ACEX 1K family. Generally not recommended for new designs. Many variants are discontinued or in last-time-buy status at Intel.

Recommended migration families (not drop-in, redesign required):

- Intel Cyclone IV E (example: EP4CE22F17 family-member options)

- Intel Cyclone V (example: 5CEFA2 series)

- Intel MAX 10 (example: 10M16 or 10M25 series for non-volatile FPGA needs)

- Cross-vendor alternatives by function (not pin-compatible): Xilinx Spartan-6 or Artix-7; Lattice ECP5

Important notes:

- These are functional successors, not pin- or software-compatible. Board, power, and timing revalidation is needed.
