EPF10K50VQI240-2 Visão geral
A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit containing an array of configurable logic blocks (CLBs/LEs), programmable interconnect, and I/O cells that the designer programs after manufacture using a hardware-description language such as VHDL or Verilog. FPGAs occupy a position between fixed-function ASICs (lowest unit cost at high volume, longest non-recurring engineering cost) and CPLDs (predictable timing, lower density) in the programmable-logic taxonomy, and the FLEX 10K family was Altera's first to embed dedicated Embedded Array Blocks (EABs) for on-chip RAM and DSP-style functions - the architectural precursor to modern System-on-Chip FPGAs.
Key features of the EPF10K50VQI240-2 include 189 maximum user I/O pins, 20,480 bits of embedded memory distributed across the EAB array, built-in JTAG (IEEE 1149.1) boundary-scan support, and multi-volt I/O capability for interfacing with 5.0 V, 3.3 V, and 2.5 V devices. The 240-pin PQFP with gull-wing leads is a surface-mount package with a 0.5 mm pin pitch on a 32 × 32 mm body, well-suited to prototype boards and legacy production runs but larger than modern BGA equivalents.
The FLEX 10K architecture pairs a fine-grained LE fabric with coarse-grained Embedded Array Blocks (EABs) used as synchronous RAM, ROM, or arithmetic functions. Each LAB contains eight LEs plus local carry and cascade chains, and the chip-wide FastTrack interconnect routes signals between LABs and I/O elements, allowing designers to map both datapath (LUT-based) and memory-intensive (EAB-based) functions on the same die.
Typical applications include industrial control boards, telecom interface cards, glue logic between microprocessors and peripherals, legacy PCI bus bridges, and test-and-measurement backplanes where the 3.3 V core and 5 V-tolerant I/O simplify mixed-voltage designs. The -2 speed grade offers a balance between timing margin and cost compared to the faster -3 and slower -1 grades in the same family.
When designing with this part, pay attention to the 3.3 V supply-rail decoupling and keep the configuration EEPROM (EPC2 or EPC16) within the Fast Passive Parallel (FPP) or Passive Serial (PS) configuration interface budget. Designers porting older FLEX 10K designs to current production should plan for migration to MAX II, Cyclone, or Lattice MachXO2/XO3 families.

Aplicações típicas
EPF10K50VQI240-2 é adequado para 6 aplicaçãos: Industrial Glue Logic and Bus Bridges, Telecom Interface Cards, Legacy PCI Bus Bridge Designs, Test and Measurement Backplanes, Motor Control and Drive Interfaces, Legacy Avionics Display Controllers.
Industrial Glue Logic and Bus Bridges
The EPF10K50VQI240-2 is well-suited to industrial glue-logic boards that bridge microprocessors to legacy peripherals. With 189 user I/O pins, 5 V-tolerant I/O banks, and 360 LABs, it absorbs wide datapath buses (ISA, PCI, VME) and protocol translation that discrete 74-series logic would require dozens of packages to implement. Its 0.6 ns propagation delay at the -2 speed grade delivers sub-100 MHz timing closure for glue-logic paths, while 3.3 V core with multi-volt I/O simplifies mixed-voltage designs that pair 3.3 V processors with 5 V peripherals, eliminating level-translator ICs and reducing BOM cost. The 240-pin PQFP is hand-solderable for prototype rework on legacy boards.
Recomendado
Telecom Interface Cards
The EPF10K50VQI240-2 is used in telecom interface cards that aggregate T1/E1 framers, HDLC controllers, and time-division multiplexers. Its 20480 bits of embedded RAM (via EABs) implement small FIFOs and elastic buffers without external SRAM, and the 125 MHz internal operation handles aggregate backplane data rates. The -2 speed grade provides the timing margin required for 50 MHz PCI or H.110 bus interfaces common in telecom backplanes. Multi-voltage I/O compatibility allows direct connection to 5 V bus drivers and 3.3 V framers on the same card, simplifying board layout and reducing the level-shifter count in mixed-signal telecom designs.
Recomendado
Legacy PCI Bus Bridge Designs
The EPF10K50VQI240-2 served as the central bridge in 32-bit 33 MHz PCI target designs through the late 1990s and early 2000s. Its 189 user I/O pins and 3.3 V / 5 V-tolerant I/O match the PCI electrical specification (5 V signaling on a 3.3 V core) without external transceivers. The 0.6 ns propagation delay at the -2 speed grade provides ample timing margin for 33 MHz PCI (15 ns cycle) even with moderate fan-out. Designers porting legacy PCI cores from FLEX 10K should evaluate migration to Cyclone or Lattice ECP5 families, which include hard PCI cores and modern SERDES.
Recomendado
Test and Measurement Backplanes
The EPF10K50VQI240-2 implements custom backplane controllers in test and measurement equipment where a fixed ASIC is uneconomical and a CPLD lacks the density. The 2880 logic elements handle state machines, address decoding, and pattern generation, while EABs provide small lookup tables and counters. The 240-pin PQFP with hand-solderable gull-wing leads simplifies prototype rework in low-volume T&M products. Multi-voltage I/O compatibility (5 V, 3.3 V, 2.5 V) interfaces directly with mixed-generation instruments, eliminating interface glue and reducing test-system integration time.
Recomendado
Motor Control and Drive Interfaces
The EPF10K50VQI240-2 is used in industrial motor-drive front-ends to implement encoder interfaces (quadrature decode, Hall-sensor sampling), PWM generation, and protection-logic consolidation. Its 360 LABs handle the multi-axis encoder sampling with deterministic latency, while EABs implement small lookup tables for sine-drive commutation. The 5 V-tolerant I/O directly interfaces with industrial 24 V opto-isolated encoder signals via external buffers, and the 0-70 °C industrial temperature range covers factory-floor enclosure environments without derating.
Recomendado
Legacy Avionics Display Controllers
The EPF10K50VQI240-2 was specified into cockpit display controllers and mission-computer interfaces where flight-certification re-designs of legacy boards kept FLEX 10K designs in production through the 2010s. The 240-pin PQFP package is well-documented in DO-254 design-assessments and the JTAG (IEEE 1149.1) boundary-scan enables in-system test of soldered boards. The -2 speed grade delivers reliable 80 MHz LVDS-compatible timing at 3.3 V. New avionics programs should plan migration to radiation-tolerant Microsemi/RTAX or Xilinx Virtex-5QV families.

Notas de projeto
The EPF10K50VQI240-2 requires a clean 3.3 V core supply with bulk decoupling of at least 100 µF tantalum plus 0.1 µF ceramic per VCC pin pair. The I/O banks can be driven at 5.0 V, 3.3 V, or 2.5 V but each bank must be powered through its own VCCIO pin; mixing VCCIO levels across banks allows direct interface to mixed-voltage peripherals without external level shifters. Power-on ramp should be monotonic, and the VCCIO supply must reach 2.5 V before VCCINT crosses 1.0 V to prevent I/O latch-up - sequence with a supervisor such as the LTC1329 if needed.
The 240-pin PQFP at 0.5 mm pitch requires a 32 x 32 mm land pattern with 0.3 mm wide gull-wing leads. Use at least 4-layer PCB with a dedicated ground plane under the device; route all 189 user I/O signals on inner or bottom layers to break out from the dense perimeter pin field. Place the configuration EEPROM (EPC2 or EPC16) within 50 mm of the DCLK and DATA pins to avoid signal-integrity issues, and add 33 Ω series damping on DCLK if the configuration trace exceeds 25 mm.
Do not confuse the EPF10K50VQI240-2 (industrial 0-70 °C, -2 speed grade) with the EPF10K50VRI240-4N (extended temperature, -4 speed grade). The Q vs R letter in the package code denotes industrial vs extended temperature; substituting one for the other can cause timing failure in timing-critical designs. Also verify the configuration mode pins (MSEL0, MSEL1) match the intended configuration interface (PS, FPP, or JTAG-only) before soldering, because misconfiguration causes a 'configuration failed' state at power-up.
Estimated: at 125 MHz internal operation, signal integrity on the FastTrack interconnect depends on the global clock network skew. For PCI designs, allocate dedicated clock inputs (CLK0-CLK5) to bus clocks; for source-synchronous interfaces, use adjacent I/O pins and the LAB-local carry chain to minimize clock-to-out skew. Source-synchronous data rates beyond ~100 MHz are not recommended due to the limited on-chip PLL capability of the FLEX 10K family.
Informações de conformidade
Compliance status not explicitly stated in verified web data; the N-suffix variants (e.g. EPF10K50VQC240-2N) indicate lead-free finish, but full RoHS/REACH documentation requires direct inquiry with the manufacturer or distributor.
