EPF6016AQC208-3 - FLEX 6000 16K Gates FPGA 208-PQFP | Intel / Altera
MPN: EPF6016AQC208-3 ✗ Cuối đờiEPF6016AQC208-3 Tóm tắt
An FPGA (Field Programmable Gate Array) is a programmable logic device (PLD) containing an array of configurable logic blocks (CLBs / LEs / LABs) interconnected by a programmable routing fabric. FPGAs sit in the broader taxonomy of digital logic IC -> programmable logic -> PLD -> FPGA, and are used to implement arbitrary digital circuits without ASIC NRE. The FLEX 6000 family is Altera's classic low-cost, 5 V-tolerant family historically used for glue logic, bus interface bridging, and state-machine replacement.
Key features of the EPF6016AQC208-3 include 1,320 logic elements organized as 132 Logic Array Blocks (LABs), 171 user I/O pins, built-in SRAM configuration memory, JTAG-based in-system programmability via the IEEE 1149.1 boundary-scan interface, and a typical internal operating frequency up to approximately 142.86 MHz. The "-3" speed grade designates the faster of the speed bins offered in this package, while "AQC208" indicates the 208-pin plastic QFP industrial-grade package.
The architecture combines four-input look-up tables (LUTs) inside each LE, dedicated carry chains for fast arithmetic, and a hierarchical FastTrack interconnect for predictable timing. The 3.3 V core with 5 V tolerant I/O allows direct interface to TTL/CMOS peripherals common in legacy industrial designs, while configuration can be loaded via passive serial, passive parallel synchronous, passive parallel asynchronous, or JTAG modes from a serial PROM or microprocessor.
Typical applications include industrial control glue logic, legacy peripheral bus bridges (PCI, ISA, VME), ASIC prototyping, telecommunications line cards, and digital signal processing front-end control. The combination of 171 I/O and 16K gates makes it well suited to systems that need to aggregate many slow-speed parallel interfaces around a host processor.
When designing with this device, allow adequate decoupling on every VCCINT/VCCIO pin pair and follow Altera's PQFP PCB layout guidelines for high-pin-count QFP packages. Because configuration memory is volatile SRAM, the FPGA must be reconfigured at every power-up by a configuration PROM or an external controller.

Ứng dụng tiêu biểu
EPF6016AQC208-3 phù hợp cho 6 Áp dụngs: Industrial Glue Logic and Bus Bridging, ASIC Prototyping and Design Validation, Telecommunications Line Cards, Legacy Peripheral Bus Bridges (PCI / ISA / VME), Test & Measurement Front-End Control, Legacy Avionics / Defense Subsystems.
Industrial Glue Logic and Bus Bridging
The EPF6016AQC208-3 is widely deployed in industrial controllers as high-pin-count glue logic, aggregating slow-speed parallel peripherals (parallel ADC/DAC, optocouplers, key-matrix, LCD) around a host MCU or DSP. Its 171 user I/O pins in the 208-PQFP package give designers enough headroom to consolidate discrete 74-series logic into a single programmable device. The FLEX 6000's 5 V tolerant inputs on a 3.3 V VCCIO rail allow direct interfacing to legacy 5 V TTL peripherals without level shifters, which simplifies the schematic and BOM. Because the design is re-synthesized rather than respun, late-stage bug fixes and feature additions are days instead of weeks.
Được đề xuất
ASIC Prototyping and Design Validation
Engineers use the EPF6016AQC208-3 to prototype ASICs and validate RTL before committing to mask costs. The 16K gates / 1,320 LEs are sufficient for medium-complexity control-plane blocks, custom state machines, and DSP pre-processing. Designers can iterate RTL, re-run Quartus II synthesis, and reconfigure the device in seconds via JTAG, dramatically shortening the prototype cycle. The 142.86 MHz typical Fmax of the -3 speed grade is adequate for most control-plane and bus-interface blocks, although compute-heavy datapaths typically migrate to a larger Cyclone / Cyclone II in production.
Được đề xuất
Telecommunications Line Cards
The EPF6016AQC208-3 has historically been used on telecom line cards for framing, channel-aggregation, and protocol-translation glue between TDM framers and a backplane ASIC. The 171 I/O and 3.3 V core with 5 V tolerant inputs let it bridge 5 V legacy framers to 3.3 V backplane ASICs without level shifters. Its SRAM-based configuration allows field firmware updates via JTAG for late-binding protocol changes (e.g., adding a new framing mode after deployment). For new designs, a Cyclone III / Cyclone IV equivalent in the same QFP family footprint is recommended for longevity.
Được đề xuất
Legacy Peripheral Bus Bridges (PCI / ISA / VME)
The FLEX 6000 series including the EPF6016AQC208-3 was a popular choice for PCI / ISA / VME bridge designs in the late 1990s and early 2000s, providing target or master logic for legacy parallel buses. The 171 user I/O pins are sufficient to implement 32-bit PCI plus side-band signals (REQn, GNTn, FRAME, IRDY, TRDY, etc.) inside a single device, eliminating multiple 74-series glue packages. Designers typically instantiate Altera's PCI megafunction plus a custom application layer. Note that 3.3 V PCI signaling requires the EPF6016A's VCCIO to be tied to 3.3 V; for 5 V PCI systems use an older FLEX 8000 or FLEX 10K.
Được đề xuất
Test & Measurement Front-End Control
In test-and-measurement instruments, the EPF6016AQC208-3 is used as a flexible front-end multiplexer / timing controller, routing analog signals to ADC channels and sequencing trigger events. Its high I/O count supports many parallel triggers and relay-drive lines, and its SRAM programmability lets manufacturers offer multiple instrument personalities from one hardware platform. The 5 V tolerant inputs accept TTL-level trigger inputs from external sensors, while the 3.3 V outputs cleanly drive modern low-voltage ADC digital inputs. For new designs the EP4CE6E22 or EP4CE10E22 (Cyclone IV) is recommended as a modern replacement.
Được đề xuất
Legacy Avionics / Defense Subsystems
The EPF6016AQC208-3 was specified into several long-lifecycle defense and avionics subsystems in the late 1990s, where its 5 V tolerance, PQFP ruggedness, and JTAG-based field reprogrammability are valued. Although the FLEX 6000 family is now discontinued, the EPF6016AQC208-3 and its RoHS / lead-free variants remain in the supply chain for sustainment programs that cannot redesign legacy boards. Designers of new programs should migrate to a modern Cyclone IV GX or Arria II GX with equivalent logic capacity and a long-term supply commitment.

Ghi chú thiết kế
Estimated: at typical utilization (~80% LEs, 50% I/O toggling, 100 MHz operation), ICCINT is roughly 150-250 mA and ICCIO per bank is roughly 20-50 mA. Provide at least four 0.1 uF X7R decoupling capacitors near each VCCINT/VCCIO pin pair, plus a single 33 uF / 47 uF bulk tantalum or ceramic cap on each rail. Use a low-impedance 3.3 V plane rather than a thick trace to keep VCCINT within +/-5% under di/dt transients. Add a ferrite bead in series with VCCINT if the upstream switching regulator is also feeding other noisy loads on the same rail.
Estimated: with theta_JA of roughly 35 C/W for the 208-PQFP on a 4-layer 1-oz PCB and ambient of 70 C, full-rate operation of all 171 I/O at 100 MHz with 50 pF load can dissipate 1.0-1.4 W, pushing junction temperature near 110-120 C. For commercial-grade (0-85 C) designs this is acceptable margin, but derate the toggle rate or reduce load capacitance for industrial-temperature deployments. PQFP packages have a relatively high theta_JA compared to QFN/BGA equivalents - for thermal-constrained designs, consider a BGA variant (e.g., FLEX 6000 BGA) if your design can be migrated.
Follow Altera's PQFP layout guidelines: use 0.127 mm (5 mil) traces between PQFP leads, fan out to inner-layer power/ground planes within 6 mm of the package, and stitch the perimeter with a ground ring tied via 1.0 mm-pitch vias to the inner ground plane. Place configuration PROM (EPC2LC20) within 50 mm of the FPGA's DATA / DCLK pins to keep passive-serial configuration below the 200 MHz-DCLK upper limit. Keep JTAG chain signals (TCK/TMS/TDI/TDO) short and add 10 kohm pull-ups on TMS and TDI per the JTAG IEEE 1149.1 recommendation.
Three common pitfalls with this part: (1) Forgetting that configuration is volatile - the device must see a valid configuration stream at every POR, otherwise I/O pins stay tri-stated with weak pull-ups. Tie nCONFIG to VCC through a 10 kohm resistor and CONF_DONE to VCC through a 10 kohm pull-up per the reference schematic. (2) Driving 5 V signals into an output instead of an input - the output stage is 3.3 V and cannot source 5 V. (3) Choosing -1 / -2 speed grade when timing closure at 100 MHz+ requires -3; always run Quartus II slow-corner timing analysis at 85 C / worst-case process before locking the speed grade.
The 208-PQFP lead pitch is 0.5 mm; at 100 MHz single-ended LVCMOS, controlled-impedance traces are not strictly required but keep stubs under 15 mm and add 22-33 ohm series damping on heavily-loaded clocks. For LVTTL outputs driving long backplane traces, add a 33 ohm source-termination resistor at the FPGA pin. Differential signals (e.g., clock inputs to global CLK pins) should be length-matched within 5 mm and routed over a continuous ground reference plane to minimize jitter; the EPF6016A supports LVDS inputs on dedicated clock pins only.
