EPF10K100BQC240-2 - 100K Gate FLEX-10KE FPGA, 240-PQFP | Altera
MPN: EPF10K100BQC240-2 ⚠ Lần mua cuốiEPF10K100BQC240-2 Tóm tắt
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.
Được đề xuất
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.
Được đề xuất
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.
Được đề xuất
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.
Được đề xuất
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.
Được đề xuất
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.

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.
Thông tin tuân thủ
EPF10K100BQC240-2 is a legacy Altera FPGA from the early 2000s. RoHS, REACH, lead-free, and halogen-free status were not in the verified web data. Likely non-RoHS for original production; Rochester Electronics authorized stock may be RoHS-converted depending on date code.
