What is an FPGA? A Field Programmable Gate Array is a programmable logic device that allows hardware functionality to be defined after manufacturing. The APEX-20K family pioneered system-on-a-programmable-chip (SOPC) integration, combining LUT-based logic for fine-grained state machines and datapaths with EAB blocks for high-density memory, ROM, and arithmetic functions. This hybrid architecture placed APEX-20K in the hierarchy: programmable logic device (PLD) → CPLD/FPGA → programmable SoC, with applications ranging from glue logic to full bus interfaces.
The EP20K200EQC240-1N features 367 MHz internal performance, 2.5 ns propagation delay (per distributor datasheet summaries), and supports multiple I/O standards including LVTTL, LVCMOS, PCI, and GTL+. The embedded array blocks deliver dual-port RAM, FIFO, and ROM functions without consuming logic resources. The device includes built-in boundary-scan test logic and supports the Altera ByteBlaster or MasterBlaster configuration schemes via serial or parallel modes.
Typical applications include telecommunications line cards, peripheral bus bridges (PCI to local bus), DSP co-processing front-ends, industrial control, and ASIC prototyping. The MultiCore architecture with embedded RAM makes the part particularly suited to designs that mix control logic with on-chip data buffers.
When designing with the EP20K200EQC240-1N, note that the 240-PQFP package limits fine-pitch routing for high-speed signals; engineers targeting above 100 MHz LVDS or DDR memory interfaces should consider later-generation FPGAs in BGA packages. The part is RoHS compliant and operates commercial grade 0°C to 85°C.

典型應用
EP20K200EQC240-1N 適用於 6 應用s: Telecommunications Line Cards, Peripheral Bus Bridges (PCI / Local Bus), DSP Co-Processing Front-Ends, Industrial Control and Factory Automation, ASIC Prototyping and HDL Verification, Legacy Sustainment and Long-Life Programs.
Telecommunications Line Cards
The EP20K200EQC240-1N fits telecom line-card designs that require medium-density glue logic, FIFO buffers, and bus-protocol bridging. With 168 user I/Os supporting LVTTL and LVCMOS, the device can terminate TDM bus interfaces and run protocol conversion between H.110 or proprietary backplanes. The 106,496 bits of embedded RAM in EAB blocks provides on-chip packet buffering for ATM, HDLC, or Ethernet framing without external SRAM. MultiCore architecture allows the LUT logic to handle serial-to-parallel conversion while EABs store lookup tables, freeing the device from external memory for routing decisions.
推薦
Peripheral Bus Bridges (PCI / Local Bus)
The 168 I/O count and 32x32 mm 240-PQFP package make the EP20K200EQC240-1N a natural fit for PCI-to-local-bus bridges that interface legacy microcontrollers to PCI slots. The 2.5 ns propagation delay and 33 MHz PCI compliance allow the device to handle the 33 MHz PCI target state machine with timing margin. EAB blocks implement dual-port RAM for write-post buffers, while LUT logic handles the 32-bit-to-8-bit protocol conversion. Designers should note that 5V PCI signaling requires external bus switches since the APEX-20K I/O operates at 2.5V LVTTL only.
推薦
DSP Co-Processing Front-Ends
The EP20K200EQC240-1N operates as a DSP co-processor pre-processing data streams before passing them to a fixed-point DSP. The 8,320 logic elements implement FIR filters, FFT butterflies, and address-generation logic, while the 106,496 embedded RAM bits store coefficient tables and intermediate sample buffers. At 367 MHz internal performance, the device sustains 100 MHz systolic FIR data rates. The 240-PQFP footprint simplifies PCB integration in motor-control and audio-processing boards where 32-bit DSPs from TI are paired with Altera FPGA pre-processors.
推薦
Industrial Control and Factory Automation
In factory automation, the EP20K200EQC240-1N implements deterministic state machines for PLC control, encoder decoding (quadrature, SSI, EnDat), and field-bus interfaces (Profibus, CANopen). The 0°C to 85°C commercial operating range suits cabinet-mounted equipment; for harsher environments the EP20K200E industrial variants in 240-PQFP are preferred. The MultiCore architecture separates real-time logic (LUT) from lookup-table-driven motion profiles (EAB), which is essential for multi-axis motion controllers in CNC machines.
推薦
ASIC Prototyping and HDL Verification
Designers prototyping ASIC designs use the EP20K200EQC240-1N as a verification vehicle because its 8,320 logic elements and 200K system gates map well to mid-complexity ASICs in the 100K-300K gate range. The JTAG IEEE 1149.1 interface and Altera Quartus II toolchain allow rapid design iteration. The 240-PQFP package exposes all user I/Os on accessible pins, simplifying logic-analyzer probing during ASIC bring-up. EAB blocks implement register files and small RAMs that mimic ASIC memory macros.
推薦
Legacy Sustainment and Long-Life Programs
Long-life programs such as avionics retrofits, military radios, and railway signaling equipment require continued supply of EP20K200EQC240-1N after the original manufacturer declares the part obsolete. Brokers like Avaq, Jotrin, ichome, and Chipdigger maintain tested inventory and offer re-reel services. The 240-PQFP package was widely adopted in 1999-2005 designs, so existing PCBs in deployed systems still need this exact part for decades of field support, even as the broader Altera APEX-20K product line has been end-of-lifed.

設計說明
The EP20K200EQC240-1N requires two separate supply rails: a 1.71 V to 1.89 V VCCINT core rail and a 2.5 V VCCIO I/O rail. Power-on sequencing is not strictly enforced, but Intel recommends VCCINT rises before or simultaneously with VCCIO to avoid I/O latch-up during configuration. Decoupling should include 0.1 µF X7R ceramic capacitors placed within 5 mm of every VCCINT/VCCIO/GND pair plus a single 100 µF bulk capacitor per supply zone. For designs exceeding 500 mA on VCCINT, use a low-noise LDO (such as the LT1764-1.8 or TPS7A4701 family) rather than a switching converter to meet the 50 mV peak-to-peak ripple specification.
The 240-PQFP (32x32 mm) package has a thermal resistance (theta_JA) of approximately 18 C/W with no airflow and 12 C/W with 200 LFM airflow. Estimated: at maximum toggle activity (367 MHz, all 8,320 cells active), worst-case power dissipation is 3.5 W, producing a junction temperature rise of 63°C above ambient. At 85°C commercial maximum, the device must operate below approximately 22°C ambient under worst-case switching unless airflow is applied. For high-altitude avionics or industrial control cabinets, derate toggle activity or apply forced-air cooling to maintain junction temperature below 125°C.
The 240-PQFP package uses 0.5 mm lead pitch with gull-wing leads spanning a 32x32 mm body. PCB layout should provide at least a 6 mm x 6 mm copper pour under the package center for thermal dissipation, plus a continuous ground plane on layer 2 for return-current continuity. Trace routing must avoid crossing the lead fingers with high-speed signals; length-match clock nets within 2 mm if the design exceeds 100 MHz. Configuration mode (passive serial, passive parallel, JTAG) is selected by MSEL pins — see the APEX-20K configuration handbook.
A common design pitfall is assuming APEX-20KE family devices are pin-compatible across all packages. The 240-PQFP, 208-PQFP, 356-BGA, 484-BGA, and 652-BGA variants of EP20K200E use the same silicon die but have completely different pinouts. Engineers migrating between packages must regenerate pin assignments via Quartus II — never trust cross-package pin mapping from memory. Another pitfall: the ByteBlasterMV configuration cable is obsolete; modern configuration requires USB-Blaster or Altera programming cables, and legacy parallel-port ByteBlasters no longer function on current PCs.
