What is an FPGA? An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that allows designers to configure arbitrary digital logic after manufacturing, sitting hierarchically under programmable logic -> logic IC -> semiconductor. FPGAs integrate configurable logic blocks (LABs/LEs), programmable interconnects, and I/O elements on a single die, providing a low-cost alternative to mask-programmed gate arrays and enabling fast design changes during prototyping or volume production. The FLEX 6000 family is a low-density, low-cost family historically targeted at glue-logic, bus-interface, and high-volume consumer/industrial applications.
Key features of the EPF6016QC240-3N include a maximum internal operating frequency reported around 125 MHz (with 172 MHz maximum internal frequency cited in some sources), 199 maximum user I/Os, FastTrack Interconnect routing, and multiVolt I/O supporting both 3.3 V and 5.0 V interfaces. The device is in-system programmable via Altera's ByteBlaster or BitBlaster configuration interfaces using SRAM configuration cells, allowing unlimited reprogramming.
The architecture combines 132 LABs of 10 Logic Elements each (1,320 LEs total) with four Enhanced Embedded Array Blocks (EABs) implemented as RAM/ROM blocks. The 240-pin PQFP package provides ample user I/O for parallel bus and peripheral bridging designs. The speed grade -3 indicates a moderate performance tier in the FLEX 6000 family.
Typical applications include bus-interface bridging, peripheral controllers, industrial glue logic, telecommunication line cards, and high-volume consumer products where fast design changes are needed. The -3N suffix denotes industrial temperature range (0 °C to 85 °C TJ) and is the standard commercial-grade option.
When designing, ensure VCCINT and VCCIO rails are decoupled with 0.1 µF + 10 µF capacitors near each supply pin, and respect 5.0 V I/O tolerance rules per the FLEX 6000 datasheet when interfacing to 5.0 V CMOS inputs. This part is now listed as obsolete/EOL by Intel/Altera.
This page synthesizes distributor stock, recommended cross-references, and practical design notes for engineers maintaining legacy FLEX 6000 designs in long-lifecycle systems.

典型應用
EPF6016QC240-3N 適用於 6 應用s: PCI Bus Interface Bridge, Industrial Glue Logic Replacement, Telecommunication Line Card Interface, Legacy Peripheral Controller / Embedded Glue, Display and Video Timing Controller, Prototype Gate-Array Replacement.
PCI Bus Interface Bridge
The EPF6016QC240-3N's 199 user I/O pins and 1,320 logic elements make it well suited for PCI 2.1 32-bit/33 MHz bus bridges and protocol-conversion logic between legacy and modern host buses. The 240-pin PQFP provides ample 5.0 V-tolerant I/O for parallel PCI bus signals, and the on-chip EABs can implement small FIFOs or lookup tables for command translation. Designers can place the device between a legacy 5.0 V peripheral and a 3.3 V host, leveraging VCCIO = 5.0 V on one bank and VCCIO = 3.3 V on another. Speed grade -3 comfortably meets PCI 33 MHz timing budgets for combinational bridges, while 5.0 V core tolerance preserves compatibility with legacy ASIC/ASIC peripherals.
推薦
Industrial Glue Logic Replacement
In industrial controllers, the EPF6016QC240-3N replaces dozens of 74-series TTL/CMOS glue-logic devices with a single programmable device, reducing PCB area and BOM cost. The 1,320 LEs handle extensive combinational and sequential logic for state machines, encoder/decoder pairs, and watchdog supervisors. VCCIO selection lets the part interface to 5.0 V PLC backplanes and 3.3 V microcontrollers simultaneously, eliminating level-shifters. With 199 user I/Os, the device can sink/source the wide parallel buses typical of factory automation I/O modules. Speed grade -3 provides deterministic propagation delay critical for safety interlocks. Designers should follow FLEX 6000 datasheet recommendations for industrial EMI/EMC filtering on each I/O bank.
推薦
Telecommunication Line Card Interface
The EPF6016QC240-3N is well matched to legacy telecom line cards where 16K gates of programmable logic is needed for T1/E1 framers, HDLC controllers, and time-slot interchangers. The 199 user I/Os comfortably handle the parallel TDM backplane plus serial control interfaces, while the 5.0 V core tolerance interfaces directly to legacy line-card ASICs. On-chip EABs implement small elastic buffers and pattern-matching tables without external SRAM. Speed grade -3 meets typical T1 (1.544 MHz) and E1 (2.048 MHz) timing budgets with significant margin. The 240-pin PQFP package is preferred over BGA in through-hole-probe-friendly line-card designs for in-field repair.
推薦
Legacy Peripheral Controller / Embedded Glue
In long-lifecycle embedded systems, the EPF6016QC240-3N consolidates scattered address-decoding, interrupt-control, and DMA-handshake logic into one programmable device. With 1,320 LEs and 199 user I/Os, it can handle 8/16-bit microcontroller peripheral expansion, IDE/ATA disk controllers, and parallel-port emulation. VCCIO flexibility enables direct connection to both 5.0 V legacy peripherals and 3.3 V processors. Speed grade -3 supports typical microcontroller bus speeds up to ~50 MHz. The SRAM-based configuration allows unlimited in-system reprogramming during development, and the FLEX 6000 design toolchain (Quartus legacy versions) supports schematic and VHDL/Verilog entry.
推薦
Display and Video Timing Controller
The EPF6016QC240-3N's combination of 199 I/Os and 1,320 LEs is well suited for legacy VGA/CRT timing controllers, character-generator overlays, and simple LCD panel interfaces. The 5.0 V I/O tolerance lets it drive CRT analog interfaces directly via companion DACs, while EABs implement video line buffers and lookup-table-driven gamma correction. Speed grade -3 supports pixel clocks up to ~125 MHz depending on logic depth, sufficient for VGA (25 MHz), SVGA (40 MHz), and XGA (65 MHz) timings. Designers can implement multi-mode autodetection by reconfiguring the FPGA at boot via the ByteBlaster serial interface.
推薦
Prototype Gate-Array Replacement
The EPF6016QC240-3N is ideal as a mask-programmed gate-array prototype, allowing designers to validate 16K-gate ASICs before committing to NRE charges. The same 240-pin PQFP footprint and 199 I/Os match common gate-array pad-ring designs, enabling drop-in prototype boards that can later be replaced by the production ASIC. In-system SRAM programmability supports unlimited design-iteration cycles, and Quartus II design tools (legacy) provide direct migration paths to HardCopy structured ASICs. The 5.0 V core voltage matches the original gate-array power specification, simplifying prototype-to-production transition.

主要差異化特點
- Highest I/O count in the FLEX 6000 family (對比EPF6016AQC208-3N)
- Same-die drop-in compatibility with EPF6016QC240-3 (對比EPF6016QC240-3)
- Speed grade -2 available in same footprint (對比EPF6016QC240-2N)
設計說明
Per the FLEX 6000 datasheet, VCCINT (5.0 V) and VCCIO (3.3 V or 5.0 V) must each be decoupled with a 0.1 µF ceramic capacitor placed within 5 mm of every VCC pin, plus one bulk 10 µF tantalum or ceramic capacitor per supply rail. The EPF6016QC240-3N has 12 VCCINT and 8 VCCIO pins distributed around the 240-PQFP package for optimal power-integrity; designers must populate ALL of them. During configuration the device draws ICCINT configuration current; ensure the regulator can source the inrush peak.
The 240-pin PQFP package has a theta_JA of approximately 25-30 C/W in still air, so the EPF6016QC240-3N does NOT normally require a heatsink at typical 5.0 V operating frequencies. However, in enclosed industrial enclosures with limited airflow, junction temperature can rise; verify with a thermal probe or by using the FLEX 6000 power estimator. Speed grade -3 versus -2 does not significantly change power dissipation. For long-term reliability, keep junction temperature below 100 °C.
Use a 4-layer PCB with continuous power and ground planes for the EPF6016QC240-3N. Route all 199 user I/Os with controlled-impedance traces if any signal exceeds 50 MHz, and keep FastTrack Interconnect delay paths short. The 32 x 32 mm PQFP land pattern is large; allow adequate breakout area for 0.5 mm-pitch gull-wing leads. Place the configuration PROM (e.g., EPC1 or EPC2) within 50 mm of the DATA0/DCLK/nCONFIG pins to avoid configuration errors.
Do NOT mix VCCIO = 3.3 V and 5.0 V on the same I/O bank - each bank must be configured for a single voltage via its VCCIO pins. Failing to connect nCONFIG through a 10 kΩ pull-up to VCCINT prevents configuration from initiating. The OE/CLKUSR pin must be tied to logic-high or logic-low as required by the design - leaving it floating causes unpredictable behavior. Finally, ensure JTAG chain order matches the BSDL file; TCK/TMS/TDO/TDI on EPF6016QC240-3N follow the standard 1149.1 layout.
