EP20K200RC208-1X 概述

The Intel (formerly Altera) EP20K200RC208-1X is a member of the APEX-20KE programmable logic family, delivering 200,000 gates of MultiCore architecture logic in a 208-pin Power Quad Flat Pack (PQFP/RQFP) package. Built on a 0.18 µm CMOS process with a 1.8 V core supply, the device integrates look-up table (LUT) logic, product-term logic, and embedded memory blocks, supporting system-on-a-programmable-chip (SOPC) integration for high-density designs.

An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that engineers can reconfigure after manufacturing to implement custom digital logic. APEX-20KE extends the APEX-20K architecture by adding LVDS I/O support and a 1.8 V core, occupying the voltage regulator -> power management IC -> programmable logic -> semiconductor IC hierarchy within embedded systems. Compared with earlier 2.5 V APEX-20K devices, the -20KE family reduces power consumption while increasing logic density and signal integrity for high-speed interfaces.

Key features include 8,320 logic elements, 106,496 bits of embedded RAM distributed across four lanes, 4 PLLs (where equipped), MultiVolt I/O supporting 1.8 V, 2.5 V, 3.3 V, and 5.0 V mixed-voltage interfacing, and LVDS support on select I/O banks. The "-1X" speed grade corresponds to a -1 device in the PQFP-208 pinout. Four enhanced PLLs with programmable phase shifting support clock multiplication, division, and delay, while the LVDS-compatible I/O enables high-speed serial data transfer up to 840 Mbps per channel.

Typical applications for the EP20K200RC208-1X include telecommunications infrastructure (channelized TDM, ATM, and SONET/SDH processing), high-speed data-path and protocol bridging, custom ASIC prototyping, DSP coprocessor glue logic, and PCI/PCI-X bus interfaces. The 200 K-gate density makes it suitable for mid-volume designs that exceed the capacity of CPLDs but do not yet justify a full ASIC NRE cost.

When designing with this part, account for the PQFP-208 package's fine 0.5 mm pitch lead frame - PCB layout requires controlled-impedance routing and careful thermal management for sustained operation. Configuration data is loaded via the IEEE 1149.1 JTAG interface or supporting configuration devices, with built-in CRC verification for in-system reliability.

🔧

Custom ASIC Prototyping and Emulation

Engineers use the EP20K200RC208-1X as an ASIC prototyping vehicle because its 200 K gates and configurable I/O let them emulate mid-density ASICs in real-time. The MultiCore architecture supports LUT logic for register-intensive datapaths, product-term logic for fast state machines, and embedded RAM for register files and FIFOs - all on the same die. Designers can re-spin in-system via JTAG in hours rather than mask weeks. The 1.8 V core plus MultiVolt I/O also lets prototypes drive the same 2.5 V, 3.3 V, and 5 V peripherals as the final ASIC, accelerating validation before committing to mask sets.

DSP Coprocessor Glue Logic

In designs combining a microprocessor or DSP with custom hardware, the EP20K200RC208-1X serves as the data-path glue: address decoding, FIFO arbitration, DMA channel multiplexing, and protocol bridging between host CPUs and accelerators. Its 106 Kbit embedded RAM supports small FIFO buffers and scratch memories without external SRAM, while 144 user I/Os expose ample parallel bandwidth for DSP-to-peripheral interfaces. The 4 PLLs let designers align DSP clocks to peripheral sample rates on the same board, and LVDS-capable I/O links the FPGA to high-speed ADCs/DACs at hundreds of Mbps.

PCI / PCI-X Bus Interface Bridge

The EP20K200RC208-1X implements PCI 32-bit/33 MHz and PCI-X 64-bit/66 MHz target and master interfaces commonly found in legacy industrial PCs, data-acquisition cards, and embedded SBCs. Its PCI-compliant MultiVolt I/O bank supports the 3.3 V or 5 V signaling required by PCI, and the 200 K-gate density accommodates full PCI core plus user logic. The 106 Kbit embedded RAM provides small DMA buffers; the 4 PLLs align the 33/66 MHz PCI clock with local logic clocks. Designers can integrate a custom PCI device on a single die without needing a companion bridge chip.

Industrial Control and Legacy I/O Expansion

Factory-automation controllers often re-use the EP20K200RC208-1X as a programmable I/O expander that translates between parallel PLC backplanes, serial fieldbuses, and proprietary control protocols. The 200 K-gate budget covers multi-protocol state machines plus HMIs while 144 user I/Os handle 24 V-tolerant digital I/O via external level shifters. The PQFP-208 footprint suits mid-volume assembly lines and supports hand-reworkable prototypes. Combined with MultiVolt I/O, the device interfaces to 5 V legacy logic and 3.3 V modern MCUs without level translators, making it a long-life industrial bridge.

EP20K200RC208-1X vs EP20K200EQC208 - which is better for telecom designs?

Both devices share the same APEX-20KE die but differ in package and temperature grade. The EP20K200RC208-1X is the commercial-grade PQFP-208 variant; EP20K200EQC208 is the QFP-208 industrial/extended temperature version. Choose EP20K200EQC208 for telecom gear needing -40 °C to +85 °C operation; choose EP20K200RC208-1X when cost matters and operating temperature stays within 0-85 °C.

What is the best drop-in replacement for EP20K200RC208-1X?

For a true drop-in replacement on the same PQFP-208 footprint, the strongest candidate is EP20K200RC208-1N, the same die in an industrial/lead-free packaging variant listed in the XAIPART internal catalog. Functionally, the APEX-20KE family offers the same die in different speeds and packages (FC484, EBC652, EFC672); a true pin-to-pin alternative requires the same 208-pin PQFP pinout and speed grade.

Can EP20K200FC484-1X replace EP20K200RC208-1X?

EP20K200FC484-1X is not pin-to-pin compatible with EP20K200RC208-1X because it ships in a 484-pin FineLine BGA versus the 208-pin PQFP, even though it shares the same APEX-20KE die. PCB rework would be required. Use EP20K200FC484-1X as a functional equivalent on new layouts but not as a direct solder-on replacement for the PQFP-208 footprint.

When should I choose EP20K200RC208-1X over a Cyclone FPGA?

Choose EP20K200RC208-1X when supporting legacy APEX-20K/20KE designs where re-validation cost outweighs migration savings, or when industrial/avionics customers have hard-bill-of-material requirements that list the APEX-20K family. Choose a modern Intel Cyclone IV/V FPGA for new designs: lower cost, lower power, higher logic density, and active lifecycle support. APEX-20KE remains useful for legacy firmware and spare-parts markets.

Where to download the EP20K200RC208-1X datasheet PDF?

The official APEX-20KE datasheet (DS-APEX20KE) is published at the Intel Programmable Solutions Group website. Search for "APEX-20KE Data Sheet" on intel.com or access via Altera's legacy documentation archive. The datasheet contains the device family overview, electrical characteristics, pin tables for each package option, and configuration guidelines; verify the datasheet revision matches the device marking on your unit.

Where can I find the pinout of EP20K200RC208-1X?

The PQFP-208 pin assignment for EP20K200RC208-1X is documented in the APEX-20KE datasheet's Pin Tables section, listed under the PQFP/RQFP-208 column. The Intel/Altera legacy pinout files (.pin or .pof) are also available in the Quartus II 32-bit edition supporting APEX-20K, although Quartus II no longer ships in production; LCSC and chip1stop also publish the pinout diagram for this specific part.

What are the key specifications of EP20K200RC208-1X that engineers should know?

The EP20K200RC208-1X integrates 200 K system gates / 8,320 LEs and 106,496 bits of embedded RAM on a 1.8 V core in a 208-pin PQFP. It features MultiCore architecture combining LUT, product-term, and memory blocks, four enhanced PLLs, MultiVolt I/O supporting 1.8 V-5.0 V mix, and LVDS support on select banks. The part is obsolete; sourcing is via Rochester Electronics, LCSC, and open-market brokers as of 2026-09-07.

选型指南

Choose EP20K200RC208-1X when supporting legacy APEX-20KE designs that require a 1.8 V core, LVDS I/O, and the PQFP-208 surface-mount footprint for hand-reworkable assembly. Choose EP20K200RC208-1N as a drop-in alternative when you need the same die in a lead-free industrial variant (Site MPN-listed). Choose EP20K200RC208-1 only if the existing design was built around the 2.5 V APEX-20K core - substituting -1X into an APEX-20K board without changing the LDO will damage the part. Avoid BGA siblings (EP20K200FC484-1X, EP20K200EQC240-2X) when true pin-compatibility on the PQFP-208 footprint is mandatory. For all new designs, prefer a current Intel Cyclone IV/V or Cyclone 10 FPGA unless legacy BOM constraints mandate APEX-20KE.

设计说明

Estimated: APEX-20KE core current scales roughly with toggle rate; typical VCCINT draw is 100-300 mA at low utilization and 600-900 mA at high toggle rates. Use a low-noise 1.8 V LDO rated at least 1 A continuous (e.g., a TI TPS7A45 or equivalent) and decouple with 0.1 µF + 10 µF ceramic per VCCINT pin. I/O banks (VCCIO1-8) can each be supplied independently at 1.8/2.5/3.3/5.0 V; place a 0.1 µF cap at every VCCIO pin and a bulk 10 µF per bank. Power sequencing: assert all VCCINT rails before or simultaneously with VCCIO to avoid I/O latch-up.

The PQFP-208 has 0.5 mm pitch gull-wing leads - keep-out zones should allow at least 5 mm of unbroken plane beneath the package for thermal spreading and ground return. Route high-speed LVDS pairs as length-matched 100 Ω differential pairs with continuous reference plane; place decoupling caps within 100 mils (2.5 mm) of each VCCIO and VCCINT pin. Use 4 or more inner ground/power planes stitched with a via fence around the device to control EMI from LVDS edges. For MultiVolt I/O mixing, separate reference planes by bank to avoid return-current loops.

Configuration data is loaded via JTAG (IEEE 1149.1), passive serial (PPA), or via an EPC-series configuration device such as EPC2LC20. JTAG is preferred for in-system reprogramming during development. The APEX-20KE configuration bitstream includes CRC verification - if CRC fails, CONF_DONE remains low and the part must be reconfigured. Reserve the nCONFIG, nSTATUS, and CONF_DONE pins to external 10 kΩ pull-ups so configuration errors do not latch the device into a non-functional state.

Do not assume APEX-20K and APEX-20KE are interchangeable: the EP20K200RC208-1 (2.5 V APEX-20K) and EP20K200RC208-1X (1.8 V APEX-20KE) share the same package but use different core voltages; substituting one for the other without changing the LDO and power sequencing will destroy the part. Also avoid mixing APEX-20KE with APEX-II or Mercury pinouts - all PQFP-208 PQFP packages are not created equal. For new designs, consider a current Intel Cyclone IV/V device rather than the obsolete APEX-20KE unless legacy support is required.
