EPF10K100BQC240-2 Tóm tắt

The Altera (Intel) EPF10K100BQC240-2 is a member of the FLEX-10KE embedded programmable logic device family, providing 100,000 system gates and 4,992 logic elements (LEs) in a 240-pin Plastic Quad Flat Pack (PQFP) measuring 32x32 mm. It integrates 24,576 RAM bits organized across 4,992 cells and operates from a 4.75V to 5.25V single supply, with a -2 speed grade offering roughly 250 MHz internal performance built on a 0.22 µm CMOS process.

An FPGA (Field-Programmable Gate Array) is a programmable logic device (PLD) that lets engineers implement arbitrary digital logic by configuring an array of configurable logic blocks (CLBs), embedded memory arrays, and programmable I/O cells. Within the broader semiconductor hierarchy, an FPGA sits above standard logic ICs (which are fixed-function) and below ASICs (which are application-specific but not user-programmable). The FLEX-10KE family specifically introduced embedded array blocks (EABs) for on-chip RAM and ROM, blurring the line between traditional FPGAs and complex programmable logic devices (CPLDs).

Key features of the EPF10K100BQC240-2 include 4,992 logic elements, 24,576 RAM bits distributed across embedded array blocks, multiVolt I/O support, in-system programmability via the IEEE 1149.1 JTAG interface, and a dedicated configuration memory. The -2 speed grade denotes a mid-range timing classification within the family; -3 parts are faster, -1 parts are slower. The 240-PQFP package supports surface-mount assembly with a moderate thermal profile suitable for industrial and telecom designs.

From an architectural standpoint, the FLEX-10KE family combines a fine-grained logic fabric with coarse-grained embedded array blocks, allowing designers to implement both wide datapath functions and small glue-logic blocks efficiently. The device is configured through a serial PROM or JTAG, and once configured the logic cells implement combinatorial and registered functions at predictable, deterministic delays.

Typical applications for the EPF10K100BQC240-2 include telecommunications backplane glue logic, industrial control and factory automation interfaces, legacy PCI bus bridge designs, low-volume prototyping where ASIC NRE is unjustified, and drop-in upgrades of older FLEX-10K designs. The wide 5V tolerance and JTAG-friendly package keep it attractive for sustaining legacy hardware.

When designing with this part, note that FLEX-10KE silicon is mature and supported only via legacy Altera (now Intel) Quartus II toolchains in compatibility mode. New designs should evaluate Cyclone or MAX families, but existing EPF10K100B boards can still be manufactured and serviced using this drop-in part.

This page consolidates distributor pricing, drop-in alternatives within the FLEX-10KE family, and practical design considerations not duplicated in the legacy datasheet.

Ứng dụng tiêu biểu

EPF10K100BQC240-2 phù hợp cho 6 Áp dụngs: Telecommunications Backplane Glue Logic, Industrial Factory Automation Controllers, Legacy PCI Bus Bridge Designs, Low-Volume ASIC Replacement and Prototyping, Avionics Legacy Display Controllers, Medical Imaging Front-End Pre-Processing.

🌐

Telecommunications Backplane Glue Logic

The EPF10K100BQC240-2 fits telecom backplane bridging because its 4,992 LEs and 24,576 RAM bits provide enough capacity for glue-logic fan-out between legacy E1/T1 framers, HDLC controllers, and TDM switches while the 240-PQFP package gives 0.5 inch pitch pins that survive -40C to +85C industrial telecom environments. Designers place the device between an MPC860 PowerQUICC and discrete bus transceivers to implement parity generation, address decoding, and interrupt prioritization. The FLEX-10KE's deterministic timing and 5V-tolerant I/O are uniquely suited to multi-voltage 3.3V/5V backplane rails that still exist in installed central-office equipment.

🏭

Industrial Factory Automation Controllers

The EPF10K100BQC240-2 is well-suited for industrial PLC and machine-vision controllers because it integrates hundreds of glue-logic functions previously requiring multiple 74-series TTL packages, saving PCB area while surviving the 4.75-5.25 V supply common in factory cabinets. With 4,992 LEs the FPGA can encode/decode Profibus or Modbus frames, implement stepper-motor pulse trains, and run state machines for conveyor sequencing in parallel. The 240-PQFP package has through-hole-friendly lead frames that withstand vibration, and the industrial temperature grade (-40C to +85C) ensures operation near motors and variable-frequency drives.

🖥️

Legacy PCI Bus Bridge Designs

The EPF10K100BQC240-2 implements PCI 2.2 bus bridges between legacy 5V host processors and 32-bit add-in cards, leveraging its 4,992 LEs for parity generation, transaction-retry state machines, and IDSEL decoding. The 240-PQFP package has enough user I/O (~180 pins available) to support 32-bit PCI plus auxiliary ISA-style signals, and the 5V core supply matches the PCI 5V signaling environment. Compared to discrete TTL bridges, the FLEX-10KE provides deterministic timing for the 33 MHz PCI clock domain and keeps BOM count low in low-volume bridge designs where ASIC NRE is not justified.

🔧

Low-Volume ASIC Replacement and Prototyping

The EPF10K100BQC240-2 serves as an ASIC prototype because its 100K gate density and embedded RAM blocks match the resource budget of many mid-complexity gate-array designs from the early 2000s. Engineering teams use the FLEX-10KE to validate logic, characterize timing, and produce low-volume production runs of 50-5000 units before committing to a mask ROM. The 240-PQFP package allows hand-rework and BGA-free prototyping, while the JTAG programming interface lets designers iterate on bitstreams in minutes using Quartus II.

✈️

Avionics Legacy Display Controllers

The EPF10K100BQC240-2 implements legacy cockpit display controllers in older avionics platforms because its 5V-tolerant I/O matches the ARINC 429 and MIL-STD-1553 bus transceivers still present in many aircraft. With 24,576 RAM bits the FPGA buffers display lists, character glyphs, and stroke-vector tables for CRT-style instruments, while the 240-PQFP package offers the thermal stability needed for pressurized-cabin temperature cycling. The industrial-grade (-40C to +85C) variant supports the DO-160 environmental envelope, and Altera's mature silicon pedigree simplifies DO-254 design-assurance documentation.

💊

Medical Imaging Front-End Pre-Processing

The EPF10K100BQC240-2 handles pre-processing in ultrasound and X-ray imaging front-ends where its 4,992 LEs implement FIR filters, beamforming delays, and image-acquisition state machines at deterministic sub-microsecond latency. The 24,576 RAM bits hold line-delay buffers for scan-line assembly, and the 240-PQFP package provides the analog-friendly 0.5 mm lead pitch needed for hand-layout PCB prototypes used in FDA 510(k) submissions. The deterministic timing of FLEX-10KE fabric simplifies IEC 62304 software-of-unknown-provenance documentation, while legacy component qualification lowers regulatory risk for re-certified Class-II medical devices.

What family does the EPF10K100BQC240-2 belong to?
The EPF10K100BQC240-2 is a member of the Altera FLEX-10KE embedded programmable logic family, which combines a fine-grained logic fabric with embedded array blocks (EABs) for distributed RAM. According to the Altera FLEX-10KE datasheet, this family is the second-generation FLEX architecture with 100K system gates and 4,992 logic elements in a 240-pin PQFP package.
How many logic elements and RAM bits does the EPF10K100BQC240-2 have?
The EPF10K100BQC240-2 contains 4,992 logic elements (LEs) and 24,576 total RAM bits organized across embedded array blocks. These resources support both combinatorial and registered logic, and the EABs can be configured as single-port RAM, dual-port RAM, ROM, or FIFO buffers for glue-logic and datapath functions.

What is the difference between EPF10K100BQC240-2 and EPF10K100BQC240-3?
The EPF10K100BQC240-2 is a mid-range speed grade with approximately 250 MHz internal performance, while the EPF10K100BQC240-3 is the fastest speed grade in the same 240-PQFP package. Both parts share the same die, pinout, and resource counts (4,992 LEs, 24,576 RAM bits), so -3 is a drop-in upgrade for designs that require tighter timing margins.
What is the best drop-in replacement for EPF10K100BQC240-2?
The best drop-in replacement is EPF10K100BQC240-3, the higher speed grade of the same die in the identical 240-PQFP (32x32) package. For legacy inventory support, EPF10K100BQC240-1 (slower speed grade) is also pin-compatible. All three share the same VQFN family pinout and FLEX-10KE architecture, ensuring no PCB changes are required.
Is there a Xilinx equivalent for EPF10K100BQC240-2?
No pin-compatible Xilinx cross-equivalent exists for EPF10K100BQC240-2 because FLEX-10KE and XC4000/XC5200 use entirely different architectures, configuration bitstreams, and JTAG instruction sets. A functional cross-brand substitute with similar gate count and SRAM-based programmability is the Xilinx XC95288 or Spartan-II family, but these require PCB redesign, software-tool migration, and bitstream regeneration.
Is EPF10K100BQC240-2 still in production?
No, the EPF10K100BQC240-2 is in last-time-buy lifecycle status as of 2026-09-11. Altera (Intel) has discontinued the FLEX-10KE family, with authorized distributors offering remaining stock only. New designs should evaluate Cyclone IV, Cyclone V, or MAX II CPLDs from Intel/Altera for modern replacements.
What is the difference between FLEX-10K and FLEX-10KE?
FLEX-10KE is the second-generation evolution of the original FLEX-10K family, adding enhanced embedded array blocks (EABs), higher logic density (100K gates vs 10K-50K), and improved I/O structures. The -2 speed grade in 10KE delivers about 250 MHz internal performance versus ~125 MHz for the original FLEX-10K -2 grade, with identical PQFP package options.

Hướng dẫn chọn lựa

Choose EPF10K100BQC240-2 when you need 100K gates of FLEX-10KE logic in a 240-PQFP package with mid-range -2 speed grade performance, particularly for legacy designs requiring 5V I/O tolerance. Select EPF10K100BQC240-3 instead if your timing analysis reveals -2 is too slow - the -3 grade is a true drop-in upgrade in the same footprint. Choose EPF10K100BQC240-1 for cost-sensitive designs where the slower timing is acceptable or for industrial temperature variants. Avoid the EPF10K100BFC256 variants unless your PCB can accommodate a 256-FBGA land pattern - they require significant board rework.

Ghi chú thiết kế

The FLEX-10KE EPF10K100BQC240-2 requires multiple supply rails: VCCINT at 5.0 V for the core logic and VCCIO at 3.3 V or 5.0 V for the I/O banks. Per the datasheet, each VCC pin must be decoupled with a 0.1 µF ceramic capacitor placed within 0.25 inch (6.35 mm) of the package pin. Bulk decoupling (10 µF tantalum) is recommended at each supply entry point to the FPGA. Power sequencing is not strictly required, but holding nCONFIG low until all rails stabilize prevents inrush current spikes during configuration. Core current is approximately 30-50 mA static plus dynamic current proportional to toggle rate - expect 100-200 mA total from VCCINT in a typical design.

The 240-PQFP package has 0.5 mm (19.7 mil) lead pitch, which requires 4-mil traces between PQFP leads for fanout. Place the configuration PROM (EPC2 or EPC8) within 4 inches of the FPGA's DATA0/DCLK/nCONFIG pins to minimize skew. JTAG chain signals (TCK, TMS, TDI, TDO) must be guarded by ground traces per IEEE 1149.1 layout guidelines, and a 10 kΩ pull-up on nCONFIG plus 10 kΩ pull-up on nSTATUS (open-drain) ensures reliable configuration startup. VCCINT and VCCIO planes should be split if mixed-voltage I/O is used (3.3 V I/O bank + 5 V I/O bank on the same die).

Three common pitfalls when working with EPF10K100BQC240-2: (1) Confusing FLEX-10K (original, 5K-50K gates) with FLEX-10KE (this part, 100K gates with enhanced EABs) - bitstreams are NOT compatible between the two generations. (2) Driving VCCIO above 5.25 V permanently damages the I/O cells; use a 3.3 V regulator for the I/O bank if the system bus is 3.3 V. (3) Quartus II support for FLEX-10KE was dropped after version 13.0 sp1 - design teams maintaining legacy bitstreams must archive their Quartus projects because newer tool versions cannot re-synthesize FLEX-10KE netlists.
