Key Differentiators

  • Industrial temperature grade with junction rating to +100 °C (vs EP1S25F672C8N)
  • Drop-in compatible within the EP1S25 family (vs EP1S25F780C5)
  • Established Stratix architecture with mature toolchain support (vs EP1M350F780C7N)

Design Notes

Estimated: With 25,660 logic elements at typical 50% utilization running at 200 MHz and 1.5 V core, the EP1S25F672I7 dissipates approximately 1.5-2.5 W dynamic power plus static leakage. The 672-FBGA package requires thermal vias under the center balls and connection to inner copper planes for heat spreading. Per Stratix hardware reference designs, forced airflow (200 LFM minimum) or a heatsink attached via thermal interface material is recommended when junction temperature must remain below 100 °C for industrial environments.

The 672-ball FBGA with 1.27 mm pitch requires microvia technology (laser-drilled 0.1 mm vias) or via-in-pad construction for reliable breakout on a 4-6 layer PCB stack-up. Use a 1.5 V core plane and dedicated VCCIO planes per I/O bank voltage (1.5V/1.8V/2.5V/3.3V). Decoupling requires 0.1 µF and 0.01 µF ceramic capacitors within 100 mils of each VCCINT/VCCIO/VCC_PLL ball group; bulk 47-100 µF tantalum or polymer capacitors handle transient response for switching I/O banks.

LVDS pairs and high-speed clock traces on the EP1S25F672I7 require 100 Ω differential impedance routing with matched lengths within 20 mils. Series termination resistors should be placed within 200 mils of the driver pins. For SSTL/HSTL memory interfaces, VREF trace routing must avoid parallel routing with switching signals to prevent coupling. Use Altera's Quartus II board-level signal integrity analysis to validate transmission line effects before layout freeze.

Do not confuse the -I7 industrial speed grade with -7 timing closure; -I7 is the slowest industrial bin and may not meet timing in designs that close cleanly on -C6 or -C7 commercial parts. When migrating from commercial EP1S25F672C6/C7/C8 to industrial EP1S25F672I7, expect approximately 15-25% timing degradation and plan margin accordingly. Also note that configuration schemes (AS, AP, PS, JTAG) require specific MSEL pin strapping - consult the Stratix handbook configuration chapter before PCB layout.
