Safe Operating Area (SOA) & Thermal Characteristics
No official SOA curve available for this digital IC. Always operate within absolute maximum ratings specified in the datasheet. Ensure adequate cooling and derate as needed.
Typical Applications
EP20K100CQ208C9 is suitable for 6 applications: Telecommunications Line Card Glue Logic, Industrial Automation Controller, ASIC Prototype Validation, Legacy PCI Bridge Implementation, Digital Signal Processing Front-End, Legacy Avionics Display Controller.
Telecommunications Line Card Glue Logic
The EP20K100CQ208C9 fits legacy telecom line-card designs where 100K gates of programmable logic integrate protocol bridging, FIFO buffering, and clock-domain crossing. With 4 PLLs and 26 embedded system blocks totaling 53,248 RAM bits, it can implement multi-channel HDLC controllers or T1/E1 framer glue logic without external memory. The 208-pin PQFP package is preferred for socketed field-replaceable assemblies common in central-office equipment. Use the device's Passive Serial configuration mode to load bitstreams from a small serial EEPROM at board power-up.
Recommended
Industrial Automation Controller
For industrial PLCs and motor-control front-ends, the EP20K100CQ208C9 provides 4,160 logic elements plus 159 user I/O - sufficient for combining sensor interfacing, PWM generation, and EtherCAT or Profibus protocol handling on a single die. The 0 to 70 C commercial temperature range fits cabinet-mounted equipment, while the embedded system blocks deliver distributed dual-port RAM for inter-task data exchange. Designers benefit from Altera's legacy MAX+PLUS II toolchain that integrates schematic and VHDL entry with industrial IP libraries.
Recommended
ASIC Prototype Validation
Engineers validate ASIC RTL on the EP20K100CQ208C9 because its 100K-gate capacity matches many production ASIC designs from the early 2000s, and the SRAM-based fabric allows unlimited design iterations. The device supports in-system JTAG programming so engineers can iterate bitstreams in minutes without removing the chip from the target board. The 4 PLLs reproduce ASIC clock trees, and the 53,248 RAM bits emulate internal ASIC memory blocks for pre-silicon firmware development.
Recommended
Legacy PCI Bridge Implementation
The EP20K100CQ208C9 implements 32-bit/33 MHz PCI bridge and target interfaces using APEX 20K PCI MegaCore functions, integrating bus arbiter, target/master state machines, and configuration space registers in a single chip. Its 159 user I/O accommodate the multiplexed PCI address/data bus plus sideband signals (REQ#, GNT#, FRAME#, IRDY#). Industrial and embedded motherboards continued using APEX 20K-based PCI bridges well into the 2010s because of proven driver support.
Recommended
Digital Signal Processing Front-End
For DSP front-ends performing FIR filtering, FFT preprocessing, or sample-rate conversion, the EP20K100CQ208C9 delivers the parallel multiplier-rich fabric needed for streaming sample pipelines. Combined with external SRAM or SDRAM for coefficient storage, the device handles 16-bit audio DSP at rates up to several MSPS. Its 4 PLLs generate the multiple clock domains required for ADC interface logic, DSP datapath, and host processor interface.
Recommended
Legacy Avionics Display Controller
Military and aerospace display controllers designed in the early 2000s use the EP20K100CQ208C9 to drive LCD panels, perform video timing generation, and overlay graphics on raw video streams. Its 159 user I/O handle parallel RGB interfaces, while 53,248 RAM bits store frame buffer segments. Although the part is now obsolete, flight-qualified assemblies in fielded aircraft continue requiring this exact MPN for FAA-compliant replacement, making drop-in alternatives like C8 and C7 speed grades critical for sustainment logistics.

Key Differentiators
- Highest speed grade in the APEX 20K 100K PQFP family (vs EP20K100CQ208C8)
- Engineering sample (ES) variant indicates qualification status (vs EP20K100CQ208C7ES)
- 208-pin PQFP package supports socketed prototyping (vs EP20K100CB356C7)
Design Notes
The APEX 20K core operates at 1.8 V (VCCINT) while I/O banks use VCCIO at 2.5 V, 3.3 V, or 5 V depending on interface standard. Decouple each VCCINT pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, and add a bulk 100 uF tantalum or aluminum polymer capacitor near the device to handle inrush current during configuration. The configuration bitstream load typically draws 50-100 mA peak, so regulator headroom matters.
Use a continuous ground plane on layer 2 directly under the PQFP-208 device to provide a low-impedance return path for the 4 PLL outputs and high-speed I/O. Route DCLK and DATA0 configuration signals as a matched-length pair (within 100 mil) to avoid configuration failures. Keep PLL analog supply pins (VCC_PLL) isolated with a ferrite bead from digital VCCINT to minimize jitter.
Do not attempt to use Quartus II versions newer than 13.0 - APEX 20K device support was removed. Legacy MAX+PLUS II 10.2 or Quartus II 13.0 are the last tool versions that target this family. JTAG chain must include the EPC configuration device as the first device in the chain if both are JTAG-programmed, otherwise boundary-scan can corrupt the FPGA's configuration memory.
Compliance Information
RoHS/REACH/lead-free status not stated in the verified web data. APEX 20K family predates RoHS compliance mandates (2006), so legacy units may use SnPb finish; check distributor date code before placing orders for RoHS-restricted markets.
