EP20K100QC208-1 Présentation
An FPGA (Field-Programmable Gate Array) is a programmable logic device that combines configurable logic blocks (CLBs), programmable interconnects, and I/O cells on a single silicon die. In the broader taxonomy, an FPGA sits inside the programmable logic category alongside CPLDs, and above that the integrated circuit (IC) hierarchy. APEX 20K devices are SRAM-based, meaning configuration data must be loaded from an external PROM or microcontroller at every power-up, which makes them reprogrammable in-system but volatile. The "20K" prefix in the family name indicates the use of MegaLAB structures that combine multiple Logic Array Blocks (LABs) for higher density.
Key features of the EP20K100QC208-1 include 26,624 typical gates, 4,160 logic elements, 53,248 bits of embedded RAM distributed across embedded array blocks, 4 phase-locked loops (PLLs) for clock synthesis, and multi-standard I/O support including LVTTL, LVCMOS, PCI, and GTL+. The -1 speed grade corresponds to the slowest of the three available grades (-1, -2, -3) for the APEX 20K family, offering a tPD of about 1.6 ns as cited in third-party datasheet summaries. The 2.5 V core is supplemented by separate VCCIO banks that can be powered to interface with 3.3 V, 2.5 V, or 1.8 V logic families.
Architecturally, the EP20K100QC208-1 is built around MegaLAB columns that group 16 LABs and one embedded system block (ESB). Each ESB can be configured as either dual-port RAM, single-port RAM, ROM, or product-term logic, giving designers a flexible mix of LUT-based and product-term-based resources on the same die. The four PLLs support clock multiplication, division, phase shifting, and external feedback, which is essential for source-synchronous interfaces and frequency synthesis.
Typical applications for the EP20K100QC208-1 include telecommunication line cards, industrial control and factory automation, medical imaging front-ends, networking switches and routers, and legacy PCI bus bridges. Designers choose APEX 20K for mid-density glue-logic consolidation, bus-interface bridging, or prototyping designs destined for Altera's higher-density Stratix or Cyclone families.
When designing with this part, note that PQFP-208 has a relatively large 28 x 28 mm footprint and 0.5 mm lead pitch, requiring a multilayer PCB with sufficient via density. The SRAM-based configuration needs a serial or parallel configuration PROM such as the EPC2 or EPC16, and the JTAG chain must include the EPC device for in-system programming support.

Applications typiques
EP20K100QC208-1 convient pour 6 applications: Telecommunication Line Cards, Industrial Control and Factory Automation, Networking Switch and Router Glue Logic, Medical Imaging Front-End Signal Processing, Legacy PCI Bus Bridges and Adapters, Prototyping Designs for Migration to Modern FPGAs.
Telecommunication Line Cards
The EP20K100QC208-1 fits mid-density telecommunication line-card designs because its 4,160 logic elements and 53,248 bits of embedded RAM are well-suited to packet-classification FIFOs and ATM/AAL2 segmentation engines. The four on-chip PLLs synthesize the multiple clock domains needed for TDM buses, UTOPIA interfaces, and upstream system-side clocks. Its PQFP-208 footprint exposes enough user I/Os to drive both a 32-bit system bus and a 16-bit line-side bus simultaneously. Designers benefit from the APEX 20K architecture's product-term/LUT mix, which simplifies implementing fast CAM lookups and protocol state machines alongside datapath logic.
Recommandé
Industrial Control and Factory Automation
In industrial PLC and motor-control applications, the EP20K100QC208-1 provides the logic capacity to implement encoder interpolation, PWM generation, and PROFIBUS/MODBUS protocol stacks in a single device. The 250 MHz core frequency supports deterministic cycle times for fast-loop control, while the LVTTL/LVCMOS I/Os directly interface to 24 V optically-isolated digital inputs. The PQFP-208 commercial temperature range (0 °C to +85 °C) is acceptable for cabinet-mounted equipment with forced-air cooling. APEX 20K's embedded array blocks can also be configured as dual-port RAM for shared-memory communication between the CPU and DSP coprocessor.
Recommandé
Networking Switch and Router Glue Logic
The EP20K100QC208-1 serves as glue logic between PHY, MAC, and switch ASICs in managed Ethernet switches by implementing SPI/I2C management interfaces, LED controllers, and address-lookup tables. Its 4,160 logic elements are sufficient for 8-port Fast Ethernet MAC aggregation with QoS tagging, while the 53 Kbits of embedded RAM store MAC address filters. The four PLLs generate independent 25 MHz, 50 MHz, and 125 MHz domains needed for MII, RMII, and GMII interfaces. PQFP-208's high I/O count allows direct bus connection to external TCAM for L2/L3 lookups.
Recommandé
Medical Imaging Front-End Signal Processing
Medical ultrasound and patient-monitor front-ends use the EP20K100QC208-1 to perform beamforming coefficient multiplication, FIR filtering, and decimation in the analog front-end datapath. The 4,160 logic elements implement 32-tap FIR filters at 40 MSPS per channel for a 16-channel system, while the 53 Kbits of embedded RAM buffer A-scan lines. JTAG-based in-system programming simplifies field firmware updates in compliance with medical device change-control procedures. The 2.5 V core and 3.3 V-tolerant I/Os simplify interfacing to legacy ADC/DAC front-ends without level shifters.
Recommandé
Legacy PCI Bus Bridges and Adapters
The EP20K100QC208-1's PCI-compliant I/Os and 32-bit datapath capability make it ideal as a PCI-to-PCI bridge or PCI master/target adapter in legacy PC and industrial-PCI systems. Designers implement configuration-space registers, parity generation, and target-abort handling in the LUT fabric while using embedded RAM as posted-write buffers. The 250 MHz internal clock enables 33 MHz PCI operation with single-cycle decode latency. PQFP-208's 159 user I/Os provide sufficient headroom for the 47 PCI signals plus auxiliary local-bus and interrupt lines.

Prototyping Designs for Migration to Modern FPGAs
Designers use the EP20K100QC208-1 as a low-cost prototype target for algorithms destined for Cyclone or Stratix families, validating logic architecture and I/O planning before committing to a more expensive modern FPGA. Quartus II design files can be retargeted between APEX 20K and Cyclone III/IV with reasonable effort, preserving IP cores and state-machine definitions. The PQFP-208's 0.5 mm pitch is hand-solderable for one-off prototype builds, unlike modern BGAs that require X-ray inspection. The 53 Kbits of embedded RAM is enough to prototype moderate-sized FIFO and dual-port buffer designs.

Notes de conception
APEX 20K devices are SRAM-based and draw Icc from VCCINT (2.5 V) plus VCCIO bank supplies. Power sequencing must follow the datasheet's recommended order to prevent I/O back-powering through ESD diodes; VCCINT should rise before or simultaneously with VCCIO. For -1 speed grade at 250 MHz with all PLLs enabled, ICCINT typically reaches ~150-300 mA depending on utilization; use a low-ESR decoupling scheme of 0.1 µF ceramic per power pin plus 10 µF bulk per supply rail.
Estimated: at 2.5 V VCCINT and 250 MHz with 80 % utilization, total power is approximately 0.75-1.0 W; PQFP-208 has theta_JA around 35-40 °C/W on a standard 4-layer JEDEC test board, producing a 30-40 °C rise above ambient. For enclosed industrial enclosures without forced-air cooling, derate clock speed or use APEX 20KE (0.18 µm) variants for ~30 % lower power. Always measure with a thermocouple on the lead frame during qualification.
PQFP-208 has a 0.5 mm lead pitch and gull-wing leads; PCB land pads should be 0.30 mm wide with 1.50 mm length and exposed soldermask-defined pads. Use a 4-layer stackup with continuous VCCINT and GND planes under the device to provide low-impedance supply and thermal spreading. Add a 5 mm copper flood on the top layer stitched to the GND plane with 0.3 mm vias every 2 mm for thermal relief.
Do not confuse the PQFP-208 (suffix QC) with the 652-ball BGA variant (suffix BC) of the same die - they have different footprints and pinouts despite sharing the EP20K100 prefix. Always verify the package suffix in the part number before PCB assembly. Also confirm configuration PROM selection (EPC2 for serial, EPC16 for parallel) because APEX 20K does not support passive serial mode for all densities.
LVTTL and LVCMOS outputs driving >4 inches of FR4 trace should be series-terminated with 33 Ω resistors placed within 0.5 inch of the FPGA pin to dampen reflections. For clock-distribution nets above 100 MHz, use a star topology with matched trace lengths within ±0.5 inch to minimize skew across the four PLL outputs. PCI-compliant I/Os do not require external termination when used in a properly-designed 33 MHz PCI segment.
