MPN： EP20K60EQC208-2X ⚠ 最後購買機會EP20K60EQC208-2X 概覽
An FPGA (Field-Programmable Gate Array) is a programmable logic device that allows hardware designers to configure arbitrary digital circuits using a matrix of configurable logic blocks (CLBs), embedded memory blocks, and routing interconnects. The APEX-20KE belongs to the broader taxonomy: FPGA -> programmable logic -> configurable logic IC -> semiconductor. It is particularly suited to SOPC (System-On-a-Programmable-Chip) integration, where processor cores, memory, and custom peripherals coexist on a single reprogrammable device, replacing what would otherwise require multiple ASICs or a microcontroller plus external glue logic.
Key specifications of the EP20K60EQC208-2X include 32,768 system gates per the APEX-20KE datasheet, 32,768 RAM bits across embedded array blocks (EABs), 4 phase-locked loops, and a maximum internal frequency of 200 MHz with propagation delays as low as 1.72 ns. The device operates from a 1.8 V core supply (1.71 V – 1.89 V) and supports multi-voltage I/O standards (LVTTL, LVCMOS, PCI, SSTL, LVDS) on its 148 user I/O pins, all routed through 8 I/O banks.
Architecturally, the APEX-20KE family introduced MultiCore logic, embedding MegaLAB structures that group 16 logic elements (LEs) plus a single EAB into a building block that can be configured as either wide fan-in product-term logic or as LUT-based fine-grained logic. This dual-mode fabric targets both datapath-style register-intensive designs and PAL/PLA-style state-machine code. The 'X' speed grade places this part in the -2X performance bin, while the industrial 0 °C to 85 °C operating temperature range fits commercial and industrial embedded designs.
Typical applications include telecommunications line cards, industrial control glue logic, PCI interface bridging, digital signal processing pre-processing, and legacy ASIC prototyping. The wide-gate-count headroom (60K gates) makes it suitable for glue-logic consolidation where a discrete CPLD-plus-microcontroller pair would otherwise be required. A practical design tip when using this part: configure the four PLLs early in the Quartus design flow because LVDS I/O and clock-domain skew are easier to close when PLL block placement is locked before fitter routing.

典型應用
EP20K60EQC208-2X 適用於 6 應用s: Telecommunications Line Card Glue Logic, Industrial Control and PLC Backplane Interface, PCI Bus Bridge and Legacy I/O Hub, Digital Signal Processing Pre-Processing Front-End, Legacy ASIC Prototyping and Emulation, Automotive Telematics and Infotainment Legacy Modules.
Telecommunications Line Card Glue Logic
The EP20K60EQC208-2X is well suited to telecom line-card glue logic where 60K gates and 148 user I/Os replace multiple discrete CPLDs and FIFOs. With 4 PLLs and 8 I/O banks, it can bridge between a network processor ASIC and backplane SERDES while supporting multiple voltage standards (LVTTL, LVCMOS, SSTL, LVDS). The 200 MHz internal fmax comfortably handles TDM and packet-protocol state-machine timing. Its MultiCore fabric mixes LUT and product-term logic, so PAL-style glue and register-rich datapaths can coexist on the same device. Power dissipation at 1.8 V core is moderate even at full I/O switching.
推薦
Industrial Control and PLC Backplane Interface
In PLC backplane and industrial control systems, the EP20K60EQC208-2X functions as the consolidated programmable logic between a microcontroller host and field-bus transceivers. The 148 user I/Os comfortably absorb parallel digital I/O, encoder feedback, and UART/SPI multiplexing without external bus expanders. Its 0–85 °C industrial temperature range and 0.22 µm CMOS process give it a long operating-life track record in factory automation hardware. The 4 PLLs generate deterministic clock domains for motor-control PWM and encoder sampling, while the 32,768-bit embedded RAM supports circular buffers for protocol framing.
推薦
PCI Bus Bridge and Legacy I/O Hub
The 1.8 V core and multi-voltage I/O capability make the EP20K60EQC208-2X a natural fit for PCI 2.2 / PCI-X bridge designs and legacy I/O hub applications. 32,768 bits of EAB RAM provide buffering for burst transfers while the LUT fabric implements 32-bit parity/generate logic in a few hundred logic elements. The 148 user I/Os can break out a full 32-bit PCI bus plus an additional expansion connector. With propagation delays as low as 1.72 ns, the device meets 33 MHz PCI timing with margin, and at -2X grade can stretch to 66 MHz PCI-X applications.
推薦
Digital Signal Processing Pre-Processing Front-End
For DSP pre-processing, the EP20K60EQC208-2X acts as a FIFO/buffering/format-conversion stage ahead of a dedicated DSP processor. Its embedded array blocks (EABs) implement 36-bit-wide registers and small FFT butterfly structures while the LUT fabric handles sample-rate conversion and address generation. With 4 PLLs, multiple synchronized clocks can feed parallel ADC/DAC pairs at the FPGA boundary. 60K gates of headroom let designers pre-aggregate several data streams before handoff, eliminating a separate preprocessing ASIC in radar, sonar, and instrumentation signal chains.
推薦
Legacy ASIC Prototyping and Emulation
The 60K-gate density and SOPC-class MultiCore architecture make the EP20K60EQC208-2X a strong ASIC prototyping vehicle for medium-complexity chips. Designers can map RTL-to-APEX-20KE with the Quartus II toolchain and run at speed (200 MHz internal) to validate bus protocols and timing before committing to silicon. The same die in PQFP-208 makes hand-rework easy during prototype bring-up, and the -2N lead-free variant supports pre-compliance validation for customers transitioning to Pb-free assembly.
推薦
Automotive Telematics and Infotainment Legacy Modules
Although the EP20K60EQC208-2X is not AEC-Q100 qualified, it appears in legacy automotive telematics and infotainment modules where its long production track record and well-known software toolchain support are valued. 148 user I/Os handle display interface, audio routing, and CAN/LIN multiplexing, while the 4 PLLs generate pixel clocks for LVDS display panels. Engineers maintaining these long-lifecycle automotive systems can rely on authorized aftermarket suppliers (Rochester Electronics, DigiKey legacy stocking) to keep fleet vehicles supported without PCB redesign.

主要差異化特點
- Drop-in same-package variant with lead-free terminal finish for RoHS-compliant builds (對比EP20K60EQC208-2N)
- Higher internal fmax for timing-critical designs (對比EP20K60EQC208-1X)
- Best price/availability balance in the APEX-20KE 60K PQFP family (對比EP20K600EFC672-2X)
設計說明
The APEX-20KE EP20K60EQC208-2X core operates at 1.8 V ±5% (1.71 V to 1.89 V). Estimate core current draw at ~50 mA per 1,000 logic elements at 100 MHz toggle rate, so the 2560-LE device draws roughly 0.1–0.3 A core current under typical load. I/O banks draw additional current proportional to switching frequency and load capacitance; decoupling requires 0.1 µF ceramic on every VCCIO/VCC pin plus a bulk 47–100 µF tantalum. Estimated core power dissipation at full 200 MHz toggle is ~1–1.5 W; design the LDO/impedance regulator headroom accordingly.
PQFP-208 packages require thermal vias under the die flag or full-power copper pour on top/bottom layers to keep the junction temperature within the 0 °C–85 °C commercial-industrial grade. Per the APEX-20KE datasheet, the 208-PQFP theta_JA is approximately 20–25 °C/W on a 4-layer PCB with standard copper. Place bulk decoupling capacitors within 100 mil of each supply pin and route VCCIO banks separately to avoid I/O supply contention.
Do not confuse -1, -2, -1X, -2X, -2N speed-grade suffixes: -1/-2 are commercial base, -1X/-2X are extended-temperature or X-fab variants, -2N is the lead-free Pb-free version. Mixing these can cause timing failure because the fmax varies by ~30% between -1 and -2 grades. Also confirm JTAG configuration mode (PS, AS, JTAG) before PCB layout — APEX-20KE requires a configuration device or download cable for bitstream loading on every power-up.
Route PLL analog supply pins (VCC_PLL) from a filtered linear regulator; noise on PLL supplies directly couples to clock outputs. The 208-PQFP allocates dedicated PLL supply pins that must be bypassed with 0.1 µF + 10 µF and routed with a star topology from the regulator. Differential LLM-related I/O (LVDS) must be length-matched within 50 mil to avoid duty-cycle distortion at the 200 MHz internal frequency.
合規資訊
EP20K60EQC208-2X uses standard tin-lead (SnPb) terminal finish and is therefore non-RoHS; for RoHS builds use the EP20K60EQC208-2N drop-in. Part is not AEC-Q100 qualified; for AEC-Q100 systems, evaluate automotive-grade FPGAs such as Cyclone IV E GX or Xilinx Spartan-6.
