An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that the designer can program after manufacturing. FPGAs sit at the top of the programmable logic hierarchy: programmable logic device (PLD) -> complex programmable logic device (CPLD) -> FPGA. They are used to implement arbitrary digital logic, glue logic, signal processing pipelines, and full processor subsystems without fabricating a custom ASIC. The APEX-20K family was Altera's first SOPC (system-on-a-programmable-chip) platform, integrating look-up tables for register-intensive functions and product-term logic for arithmetic paths into a single fabric.
Key features of the EP20K200RC240-3 include 174 maximum user I/O, 4 Embedded System Blocks (ESBs) supporting True Dual-Port RAM at up to 311 MHz in -3 speed grade, an internal MultiTrack interconnect for high-speed routing, and IEEE 1149.1 JTAG boundary-scan support. The 1.8V core (VCCINT) with 2.375V to 2.625V supply tolerance and 3.3V tolerant I/O make it well suited for mixed-voltage board designs.
Typical applications span telecommunications line cards, industrial control, high-speed data processing, DSP co-processing, and legacy ASIC replacement. The wide I/O count and embedded RAM make it effective for bus-bridging, custom peripheral controllers, and parallel DSP pipelines. Designers should configure the device with Quartus II (legacy) or Max+Plus II to generate the configuration bitstream loaded into the on-chip SRAM cells.
This page synthesizes distributor pricing, drop-in pin-compatible alternatives, and practical design notes not found in the manufacturer datasheet alone. Engineers comparing this part against modern Cyclone or Lattice alternatives should weigh the 1.8V core supply, BFQFP-240 footprint, and active Altera/Intel legacy support window.

典型應用
EP20K200RC240-3 適用於 7 應用s: Telecommunications Line Card Interface, Industrial Motor Control and Drive, High-Speed Data Acquisition Front-End, ASIC Replacement and Glue Logic Consolidation, Custom DSP Co-Processor Pipeline, Embedded Industrial Networking Bridge, Legacy Test and Measurement Backplane.
Telecommunications Line Card Interface
The EP20K200RC240-3 fits telecom line cards as a glue-logic and bus-aggregation controller, leveraging its 174 user I/O and 106,496 system gates to interface between TDM backplanes and parallel data paths. Its 1.8V core and 3.3V-tolerant I/O simplify mixed-voltage board designs common in legacy telecom racks. Placed between an upstream PHY and a downstream processor, the device can run custom framing, error correction, and rate-adaptation logic in hardware. Designers should pair it with a 53,248-bit embedded RAM block to buffer packet fragments, and use Quartus II SOPC Builder to instantiate the Avalon bus. Trade-off: the APEX-20K fabric is older than modern Cyclone IV/V and consumes more power per logic element.
推薦
Industrial Motor Control and Drive
The EP20K200RC240-3 suits industrial motor drive controllers where deterministic logic and abundant I/O outweigh absolute clock speed. With 174 user I/O it can drive PWM channels, encoder feedback, and Hall-sensor inputs simultaneously while running state machines for commutation and current-loop control. Speed grade -3 (slower, low-power) is acceptable in motor control where PWM frequencies stay below 100 kHz. The 240-BFQFP exposed-pad package offers excellent thermal dissipation for hot control cabinets. Compared to a microcontroller, this FPGA offers deterministic latency and parallel I/O handling at the cost of higher BOM and configuration overhead. Recommended for legacy industrial designs or retrofits where the existing APEX-20K firmware is reused.
推薦
High-Speed Data Acquisition Front-End
The EP20K200RC240-3 is well-matched to high-speed data acquisition front-ends that require parallel ADC interfacing, FIFO buffering, and custom DSP pipelines. Its 4 embedded system blocks (ESBs) provide up to 53,248 bits of true dual-port RAM ideal for sample-rate buffers between ADCs and a downstream DSP. The 174 I/O can directly sample 16-bit parallel ADCs running at 80-100 MSPS and perform real-time filtering or decimation. Speed grade -3 supports internal fabric clocks around 150-180 MHz. Pair with the Apex 20KE SignalTap II logic analyzer in Quartus II to verify timing closure during board bring-up. Trade-off: APEX-20K lacks hard DSP blocks, so designers must implement MAC units in LUTs, increasing logic element usage.
推薦
ASIC Replacement and Glue Logic Consolidation
The EP20K200RC240-3 is commonly used to replace obsolete ASICs in legacy designs where redesigning the silicon is cost-prohibitive. Its 106,496 system gates can absorb the typical density of a mid-1990s gate-array ASIC, while its reprogrammability enables late-stage bug fixes. The 240-BFQFP package and 1.8V core are pin-compatible with many existing boards, making it a mechanical drop-in upgrade. Designers migrating from a discontinued ASIC benefit from Quartus II SOPC integration to add Nios soft-processors for system control. The NRND status is acceptable for legacy support windows where the design must simply function. Trade-off: not recommended for new high-volume designs given APEX-20K NRND classification.
推薦
Custom DSP Co-Processor Pipeline
The EP20K200RC240-3 serves as a co-processor in DSP pipelines where parallel arithmetic and I/O parallelism outperform microcontrollers. Designers can implement custom FIR/IIR filters, FFTs, or codec blocks in LUTs and ESBs while a host processor streams data via the parallel I/O. With 8,320 logic elements and 53,248 bits of embedded RAM, the device can handle a 64-tap FIR filter running at audio bandwidth or a small image-processing pipeline. Speed grade -3 sets internal fabric clocks at roughly 150-180 MHz, sufficient for video-rate processing of moderate complexity. Pair with external SDRAM to extend sample buffers beyond the ESB capacity. Trade-off: APEX-20K uses more power per MAC than modern FPGAs with hard DSP blocks.
推薦
Embedded Industrial Networking Bridge
The EP20K200RC240-3 fits embedded industrial networking bridges where it must translate between Ethernet, Profibus, RS-485, and CAN, while presenting a unified register map to a host PLC. The 174 I/O can directly drive multiple isolated transceivers and the 106,496 system gates can host custom frame-formatters for each protocol. The 1.8V core and 3.3V I/O simplify mixed-voltage designs where some PHY chips run at 2.5V. Speed grade -3 keeps power consumption acceptable for always-on industrial installations. Quartus II SOPC Builder can instantiate a Nios II soft-processor to run network management protocols without an external MCU. Trade-off: APEX-20K NRND status makes it suitable only for legacy support of fielded industrial equipment.
推薦
Legacy Test and Measurement Backplane
The EP20K200RC240-3 is used in legacy test-and-measurement backplanes where the FPGA performs pattern generation, scan-chain control, and custom stimulus routing. With 174 user I/O and 4 ESBs, it can drive a 16-channel mixed-signal test platform while buffering captured waveforms in embedded RAM. Speed grade -3 supports stimulus patterns at up to 100 MHz which matches most legacy ATE timing requirements. The 240-BFQFP exposed-pad package delivers thermal headroom for continuous full-power operation in test head environments. Designers use SignalTap II for on-chip debugging and Quartus II LogicLock regions to isolate test IP blocks. Trade-off: APEX-20K is supported only by legacy Quartus II 13.0 and earlier, not by modern Intel Quartus Prime Pro.

設計說明
Estimated: at 1.8V core, with 8320 logic elements running at 50% utilization and 174 I/O at 25 MHz LVCMOS33, the EP20K200RC240-3 typically draws 250-400 mA on VCCINT. Provide a 1.8V rail via an LT1764A-1.8 or equivalent low-noise LDO rated for at least 800 mA, with a 10uF tantalum plus 0.1uF ceramic decoupling network placed within 5 mm of each VCCINT pin. The exposed pad on the 240-BFQFP package must be soldered to a copper pour connected to GND for thermal dissipation. Insufficient decoupling will cause logic glitches and I/O timing violations during high-ESB read/write activity.
The 240-BFQFP exposed-pad package has 0.5 mm pitch leads, which is challenging for hand-soldering and demands reflow assembly. Use a 4-layer PCB stackup with continuous GND planes on layer 2 to minimize ground bounce. Length-match clock traces (CLK0, CLK1) to within 1 mm to avoid duty-cycle distortion; route configuration PROM data lines (DCLK, DATA, nCONFIG, nSTATUS, CONF_DONE) in a single bus with matched lengths to prevent configuration errors. Provide JTAG test points on TCK, TMS, TDI, TDO for in-system programming and boundary-scan diagnostics.
The EP20K200RC240-3 is SRAM-based and loses its configuration on every power-down. You must pair it with an EPC2 or EPC16 configuration PROM or use a microcontroller to load the bitstream via JTAG. Forgetting the configuration PROM is a common engineering error that leaves the device non-functional at first prototype. Additionally, this device is supported only by Quartus II versions up to 13.0 (legacy Intel/Altera tools); modern Quartus Prime does not support APEX-20K. Verify your toolchain compatibility before committing to this FPGA for new development.
Estimated: at 1A VCCINT current and 1.8V supply, the device dissipates ~1.8W internally. The 240-BFQFP exposed-pad package has theta_JA of approximately 18 C/W with a 4-layer 4x4 inch board and a properly soldered exposed pad, giving a junction temperature rise of ~32C above ambient. At the upper commercial limit of 85C ambient, junction temperature reaches ~117C - well within the 125C silicon limit but leaves minimal headroom. For industrial temperature (85C) operation in enclosed cabinets, add forced-air cooling or reduce fabric utilization to maintain margin.
