EP20K200CQ208C8 Tóm tắt

The Altera (now Intel) EP20K200CQ208C8 is a member of the APEX 20KC programmable logic family, providing 200,000 system gates, 8,320 logic elements, and 106,496 bits of embedded RAM in a 208-pin QFP (PQFP-208, 28x28 mm) package. Fabricated on a 0.18 µm (0.15 µm effective) CMOS process, the device operates from a 1.71 V to 1.89 V core supply (1.8 V nominal) and supports a maximum internal clock frequency of approximately 301 MHz. The 'C8' speed grade places the part in the commercial-temperature category, while the 'CQ' package code designates the 208-pin plastic QFP with gull-wing leads.

A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that allows hardware designers to configure logic blocks, routing, and I/O after manufacture. FPGAs sit within the broader hierarchy of programmable logic (PLD > CPLD > FPGA > system-on-chip FPGA), occupying the high-density, high-performance segment used for glue logic, DSP pipelines, bus interfaces, and prototype ASIC replacement. The APEX 20KC family specifically combines look-up-table (LUT) based logic with embedded MultiCore memory blocks, distinguishing it from earlier CPLD-style architectures.

Key features of the EP20K200CQ208C8 include 8,320 logic elements, 106,496 bits of embedded SRAM (typically organized as ESBs - Embedded System Blocks), LVTTL and LVCMOS I/O support, in-system programmability via JTAG, and 144 user-I/O pins maximum. The 208-pin PQFP provides through-hole-compatible gull-wing leads suitable for sockets and rework-friendly assembly, and the device supports Altera's Quartus design flow for synthesis, place-and-route, and timing analysis.

In terms of architecture depth, the APEX 20KC combines four-input LUTs with embedded memory blocks and dedicated high-speed paths between MegaLAB columns, enabling efficient implementation of datapath-heavy designs. The 1.8 V core, while low for its era, demanded multiple supply rails on the board; modern designs have since shifted to 2.5 V, 3.3 V, and sub-1 V FPGAs.

Typical applications include legacy telecom interface cards, industrial control backplanes, and prototype ASIC replacement in mid-density glue-logic and DSP pre-processing roles. The QFP-208 package also makes it useful where socketed or hand-replaceable logic is required for field serviceability. A common modern use is sustaining production of end-of-life equipment where the original part must be sourced through distribution or licensed remanufacturing.

Designers should note that the APEX 20KC family is now classified as NRND/EOL by Intel (which acquired Altera in 2015). Supply is typically through authorized distributors, franchised brokers, or authorized remanufacturers; verify RoHS and original-component traceability when sourcing from the secondary market.

Ứng dụng tiêu biểu

EP20K200CQ208C8 phù hợp cho 6 Áp dụngs: Legacy Telecom Interface Cards, Industrial Control Backplanes, Prototype ASIC Replacement, Military / Aerospace Sustainment, Medical Imaging Pre-Processing, Test & Measurement Instrumentation.

🌐

Legacy Telecom Interface Cards

The EP20K200CQ208C8 fits legacy telecom interface cards because its 200K system gates, 8,320 logic elements, and 106,496 embedded RAM bits provide the density needed to implement TDM bus bridges, framer interfaces, and HDLC controllers in a single device. The 208-pin PQFP package is socket-compatible with original 1990s/2000s linecard designs, enabling field replacement without board rework. Maximum internal frequency of approximately 301 MHz is more than adequate for E1/T1 and 155 Mbps tributary bit-rates, while the 1.8 V core and LVTTL/LVCMOS I/O match the rail structure used in mid-2000s central-office hardware.

🏭

Industrial Control Backplanes

The EP20K200CQ208C8 is well-suited to industrial control backplane glue-logic, where 200K gates are sufficient for protocol bridging (Modbus, Profibus, custom fieldbus), encoder/decoder logic, and on-board diagnostics. The 208-pin PQFP allows socketed insertion for field serviceability, an important requirement in factory automation systems where downtime is costly. Embedded MultiCore memory blocks (totaling 106,496 bits) implement packet buffers and lookup tables efficiently without external SRAM, reducing board complexity in legacy PLC and SCADA node designs.

Prototype ASIC Replacement

For prototype ASIC replacement in mid-volume designs, the EP20K200CQ208C8 offers 200K gates of logic capacity with in-system JTAG programmability via the Quartus design flow. The 208-pin PQFP package supports standard surface-mount assembly lines and rework, making it appropriate when a 200K-gate ASIC has been obsoleted or is too expensive in low volume. Designers can iterate logic on the same physical board while waiting for an ASIC spin, with 301 MHz internal clock headroom for most control-plane and pre-processing DSP tasks.

Medical Imaging Pre-Processing

In medical imaging pre-processing, the EP20K200CQ208C8 handles sensor front-end pipelines, image decimation filters, and bus-format conversion in ultrasound and X-ray detector systems where the original FPGA design has remained unchanged for over a decade. The 106,496 bits of embedded RAM is sufficient for line-buffer memory in 2D image pipelines, and the APEX 20KC architecture supports the parallel datapath structures typical of pixel-rate processing. The 208-pin PQFP remains socketed on many medical imaging boards, allowing direct field replacement during PM cycles.

For legacy industrial designs where socketed QFP replacement is required, both are pin-compatible drop-in candidates on the same PCB footprint.

EP20K200CQ208C8 vs EP20K200CB356C8 - which has more I/O?

The EP20K200CQ208C8 has 208 pins (144 user I/O maximum), while the EP20K200CB356C8 uses a 356-pin BGA package with more user I/O available. The BGA package supports higher pin counts but is not drop-in compatible with the PQFP-208 footprint.

When should I choose EP20K200CQ208C8 over EP20K200CF484C8?

Choose the EP20K200CQ208C8 when your board layout requires a socketable, through-hole-compatible QFP package with 144 user I/O. Choose the EP20K200CF484C8 when your design uses a 484-pin FineLine BGA footprint and needs higher I/O count, smaller board area, and improved signal integrity at high frequencies.

What is the best drop-in replacement for EP20K200CQ208C8?

The best drop-in replacement is the EP20K200CQ208C7ES or EP20K200EQC208-3 in the same 208-pin PQFP package, sharing identical pinout and within one speed grade. Both come from the same APEX 20KC family and require no PCB changes when swapping into a legacy socket.

Can EP20K200CB356C8ES replace EP20K200CQ208C8?

No, the EP20K200CB356C8ES uses a 356-pin BGA package and is not pin-to-pin compatible with the 208-pin PQFP EP20K200CQ208C8. PCB rework would be required, so this is not a drop-in replacement.

Where to download the EP20K200CQ208C8 datasheet PDF?

The official Altera APEX 20KC datasheet PDF can be downloaded from the Altera/Intel documentation archive at the legacy URL referenced in the part number naming convention. Authorized distributors also host copies; verify the document revision matches the lot date code when validating against production hardware.

Where to find the EP20K200CQ208C8 pinout?

The EP20K200CQ208C8 pinout for the 208-pin PQFP package is published in the APEX 20KC Device Handbook. Pin 1 is located at the top-left of the package when the index mark is oriented to the upper-left, and signals include dedicated JTAG (TCK/TMS/TDO/TDI), configuration, PLL, and user I/O banks A-D.

Hướng dẫn chọn lựa

Choose the EP20K200CQ208C8 when maintaining a legacy telecom interface card, industrial backplane, or prototype ASIC replacement where the original 208-pin PQFP socket must be reused without PCB rework. Its 200K system gates, 8,320 logic elements, and 106,496 embedded RAM bits provide sufficient density for TDM bridges, HDLC controllers, custom protocol engines, and parallel ADC/DAC front-ends. If your design needs more I/O than 144 pins or higher signal integrity at fast edge rates, migrate to a FineLine BGA variant such as the EP20K200CF484C8 (and accept BGA assembly). If your design has been using the EP20K100CQ208C8 and you need more logic capacity, the EP20K200CQ208C8 is a drop-in density upgrade in the same 208-pin PQFP socket. For new designs today, consider migrating to a Cyclone IV/V or MAX 10 device - the APEX 20KC family is NRND and the 1.8 V core is not compatible with modern low-voltage rails.

Ghi chú thiết kế

The APEX 20KC family requires three supply rails: a 1.8 V VCCINT for the core, a separate VCCIO for each I/O bank (typically 2.5 V, 3.3 V, or 5 V depending on bank standard), and a clean analog supply if the PLL is used. Decouple each VCCINT/VCCIO pin with a 0.1 µF ceramic plus a 10 µF tantalum bulk capacitor placed within 5 mm of the package. Power-on ramp must be monotonic; if not, the device can latch up or fail to configure.

Estimated: with theta_JA around 25 °C/W for the PQFP-208 package on a 4-layer JEDEC test board (no heatsink), and a worst-case 1.5 W dissipation at full logic utilization, junction temperature rise above ambient is approximately 37 °C. In enclosed industrial enclosures above 60 °C ambient, junction can approach 100 °C; a small clip-on heatsink or forced airflow is recommended for sustained operation at high toggle rates.

The 208-pin PQFP has a 0.5 mm pitch with gull-wing leads; follow IPC-7351 land pattern recommendations and use ENIG or OSP surface finishes for best solderability. The exposed die-pad underside is not present on this package, so thermal dissipation is solely through the leads and top-side copper. Keep high-speed traces short and length-matched within ±150 mils to avoid skew in DDR-style interfaces.

Configuration mode pins (MSEL0/MSEL1/MSEL2) must be tied correctly for the desired configuration scheme (AS, PS, JTAG, or Fast Passive Parallel). Mis-configuration is the most common reason boards fail to come up. Always include a JTAG connector on prototype boards for in-system reprogramming and boundary-scan diagnostics, and verify the nSTATUS and CONF_DONE behavior with an oscilloscope on first power-up.
