EPF10K100BQC240-3 Descripción general
An FPGA is a type of programmable logic device (PLD) that combines the integration density of an application-specific integrated circuit with the design flexibility of a software-defined hardware platform. FPGAs sit in the broader hierarchy of integrated circuits (ICs) -> programmable logic -> PLD -> FPGA -> SRAM-based LUT FPGA. The FLEX-10K family was one of the first commercial architectures to embed dedicated array blocks (EABs) for on-chip memory, enabling single-chip implementation of register-transfer logic plus FIFO/RAM functions for glue logic replacement, bus interfacing, and DSP pre/post-processing.
Key features include 4,992 logic cells, 6,144 RAM bits, 200 MHz typical internal performance, and 0.22 µm CMOS process technology. The -3 speed grade indicates the slowest commercial speed bin of the family, selected for cost-sensitive designs where timing closure is not the limiting factor. The PQFP-240 package was the workhorse industrial footprint for late-1990s through mid-2000s FPGA designs, providing ample I/O for 32-bit parallel buses and multi-protocol bridging.
The architecture uses SRAM configuration cells, requiring an external configuration memory (such as an EPC2 or EPC1 serial configuration device) at power-up. I/O banks support multiple I/O standards (TTL, CMOS, PCI) via per-pin configuration registers. The FLEX-10K family supports JTAG (IEEE 1149.1) boundary-scan testing and in-system programmability through the JTAG or passive serial interface, allowing board-level reconfiguration without removing the device.
Typical applications include industrial control and instrumentation, telecommunications line cards, military/aerospace systems (COTS-grade), legacy PCI/ISA bridge designs, and prototyping platforms where designers need 50K-200K gates of programmable logic with moderate clock rates. The wide 5 V tolerance simplifies interfacing with legacy TTL logic in retrofit and modernization projects.
When designing with this device, ensure that the Quartus (or legacy MAX+PLUS II) configuration bitstream is generated for the -3 speed grade. The 240-pin PQFP requires a 0.50 mm-pitch land pattern with generous copper pad relief to prevent solder joint cracking under thermal cycling. For new designs, consider migrating to a Cyclone IV or MAX 10 device in QFP, as the FLEX-10K family is mature and approaching end-of-life for new procurement.
This page synthesizes distributor pricing, drop-in same-package alternatives (speed-grade and logic-density variants of the FLEX-10K family), and practical design notes that go beyond what the manufacturer datasheet alone provides.

Notas de diseño
The 240-PQFP package has a 0.50 mm pin pitch and 32 x 32 mm body size. Use a 4-layer PCB with a continuous ground plane directly beneath the FPGA to provide a low-impedance return path for high-speed signals. Keep all signal traces within 25 mm of the package to minimize reflections. For PQFP leads, use NSMD (non-solder mask defined) pads with 0.30 mm aperture openings to ensure reliable solder joints and to avoid solder joint cracking under thermal cycling.
The EPF10K100BQC240-3 requires a 5 V core supply at 4.75 V to 5.25 V with bulk decoupling of at least 33 µF tantalum + 0.1 µF ceramic at each VCC pin pair. I/O banks can be supplied at 3.3 V or 5 V independently via per-bank VCCIO pins; mix-and-match carefully. Use a linear regulator (e.g., LM1117-5.0) rather than a switching regulator if the application is noise-sensitive, because the FLEX-10K's internal charge pumps inject supply-noise ripple at the VCC pins.
Do not confuse speed-grade suffixes: -3 is the slowest commercial grade, -2 is medium, -1 is fastest. Using a -1 grade bitstream on a -3 device, or vice versa, will cause timing failures. Always verify the device ID via JTAG before programming. Also note that the EPF10K100BQC240-3 requires an external configuration memory (EPC1 or EPC2); the FLEX-10K is SRAM-based and loses its configuration when powered down, so a configuration device is mandatory for production designs.
PQFP packages have limited thermal dissipation compared to BGA packages. Estimated: at 200 MHz toggle rate with 50% I/O utilization, internal power is approximately 0.5 W. With theta_JA around 30 °C/W for the 240-PQFP, junction temperature rise is about 15 °C above ambient - acceptable for commercial (0°C to 70°C) operation but watch thermal margins if used in industrial (-40°C to +85°C) or military-grade applications.
PQFP leads introduce ~3-5 nH of lead inductance per pin, which creates impedance discontinuities above 100 MHz. For clock and high-speed bus signals, add 33 Ω series damping resistors within 25 mm of the FPGA pin to dampen reflections. Route differential pairs with matched lengths (within 0.5 mm) and 100 Ω differential impedance. For multi-FPGA designs, source-synchronous clocking is preferable to clock distribution networks to avoid skew.
Información de cumplimiento
Compliance information not explicitly stated in verified web data. The 240-PQFP package on the FLEX-10K family typically used lead-free solder for commercial variants, but RoHS compliance must be confirmed from the lot-specific manufacturer documentation. AEC-Q100 is not applicable to FPGAs.
