EP20K100QC208-1N 概述
The Intel EP20K100QC208-1N is a member of the APEX 20K family of programmable logic devices (PLDs), delivering 100K typical gates and 4,160 logic elements in a 208-pin Plastic Quad Flat Pack (PQFP) package with 0.5 mm terminal pitch. The device combines fine-grain logic, embedded system blocks (ESBs) for memory, and high-speed I/O in a single chip fabricated on a 0.22 µm CMOS process. A speed grade of -1 places it among the highest-performance members of the APEX 20K family, supporting up to 250 MHz internal operation.
A programmable logic device (PLD) is a semiconductor whose logic function is defined by user-loaded configuration data rather than by factory mask programming. Within that hierarchy, a field-programmable gate array (FPGA) such as the APEX 20K contains an array of configurable logic blocks (CLBs), routing resources, and I/O cells. The APEX 20K family further introduced embedded system blocks that provide dual-port RAM, content-addressable memory, and product-term logic, blurring the line between FPGA and complex PLD (CPLD). The 'QC208' suffix denotes the 208-pin PQFP package, while '-1N' indicates the -1 speed grade in a commercial 0–85 °C temperature range.
Key features include 159 usable user I/Os, four dedicated fast inputs for high-fanout clocking, on-chip phase-locked loops for clock multiplication and deskew, and JTAG-based in-system programmability (ISP). The 2.5 V core supply (VCCINT) is supported by a multi-voltage I/O ring that can be configured for 2.5 V, 3.3 V, or 5 V interfaces using separate VCCIO banks. Embedded system blocks deliver up to 53 Kbits of dual-port RAM while remaining bit-stream-compatible with the APEX 20KE generation.
Architecturally, the EP20K100 partitions into MegaLAB structures that each contain 16 logic elements and one ESB. Carry-chain and cascade-chain interconnects accelerate arithmetic and wide fan-in functions, while MultiTrack routing provides predictable timing closure for high-speed designs. The device is in-system programmable through the IEEE 1149.1 (JTAG) port, supporting background reconfiguration without halting the application.
Typical applications include telecommunications line cards, industrial control and machine vision, military and avionics signal processing, and prototyping of ASIC functionality. The 208-pin PQFP package is hand-solderable and socket-compatible, making the part a popular choice for legacy designs and lab validation. The EP20K100QC208-1N is also commonly used as a glue-logic replacement for multiple 74-series TTL devices.
When designing with this device, verify the Quartus or MAX+PLUS II toolchain supports the targeted density and that JTAG chain provisioning is allocated on the board. The 208-pin PQFP offers fewer I/Os than the BGA-652 variant of the same silicon, so designers migrating between packages must re-validate pin assignments. For new designs, Intel recommends the Cyclone series instead.
This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, including source-traced specifications, EOL-aware cross references, and AEO-optimized answers to the questions procurement and design engineers actually ask.

Its 5 V-tolerant I/O banks connect directly to legacy 3.3 V and 5 V bus transceivers without level shifters. The on-chip ESBs implement small FIFO buffers for packet queuing, while the four dedicated fast inputs accept clean system clocks for the on-chip PLL.
推荐
Industrial Control and Machine Vision
The 208-pin PQFP package is hand-solderable and field-replaceable, valuable for industrial machinery retrofits. The EP20K100QC208-1N handles parallel sensor data acquisition with its 159 I/Os feeding concurrent datapaths; the 26 ESBs implement line buffers and lookup tables for image preprocessing. Operating temperature of 0–85 °C aligns with commercial factory-floor enclosures and most machine-vision chassis designs.
推荐
Legacy ASIC Prototyping and Validation
Design teams commonly use the EP20K100QC208-1N to prototype ASIC functionality before committing to mask production. Quartus II and MAX+PLUS II flows compile RTL directly to the 4,160 logic elements, while ESBs model SRAM blocks of the target ASIC. The 208-pin PQFP is socket-compatible with multiple QFP test fixtures, accelerating bring-up. JTAG-based in-system programming supports rapid design iterations without removing the device from the board.
推荐
Military and Avionics Signal Processing
The APEX 20K family meets the I/O and logic-density requirements of mid-complexity avionics buses such as MIL-STD-1553 and ARINC 429 bridges. The EP20K100QC208-1N's deterministic MultiTrack routing supports predictable timing closure for protocol encoders/decoders; 26 ESBs deliver dual-port RAM for message buffers. Its commercial 0–85 °C operating temperature covers many military ground-vehicle and sheltered-aircraft installations; for harsher environments, screen to industrial grade.
推荐
74-Series TTL Glue-Logic Consolidation
The EP20K100QC208-1N is frequently used to replace dozens of 74LS/74HC glue-logic devices on legacy boards with a single programmable part. Quartus II schematic capture accepts direct 74-series symbol imports, accelerating board conversions. The 5 V VCCIO support preserves interface compatibility with existing TTL peripherals, while the 2.5 V core reduces overall board power versus equivalent discrete logic. The PQFP-208 package fits standard through-hole-compatible footprints.
推荐
Test and Measurement Instrumentation
The 250 MHz internal operation and 1.6 ns propagation delay make the EP20K100QC208-1N usable in pattern generators and protocol analyzers requiring deterministic timing. Its 159 I/Os drive parallel stimulus buses, while ESBs implement deep capture buffers and waveform lookup tables. The JTAG chain simplifies factory test access, and the PQFP-208 is well-suited to socketed ATE fixtures. Multi-voltage I/O banks interface directly to both 5 V and 3.3 V DUTs.

What family does the EP20K100QC208-1N belong to?
The EP20K100QC208-1N is a member of Intel's (formerly Altera's) APEX 20K family of programmable logic devices. According to Altera's APEX 20K datasheet, the family combines fine-grain logic elements with embedded system blocks (ESBs) that provide dual-port RAM, CAM, and product-term logic in a single device. The 100K gate-class member integrates 4,160 logic elements across MegaLAB structures.
How many user I/O pins does the EP20K100QC208-1N provide?
The EP20K100QC208-1N provides 159 usable user I/O pins plus 4 dedicated fast inputs. According to the APEX 20K datasheet, the 208-pin PQFP package is the lower-I/O variant of the EP20K100 die; the same silicon in BGA-652 package exposes up to 488 I/Os. Designers must re-validate pin assignments when migrating between PQFP and BGA packages.
What is the supply voltage of the EP20K100QC208-1N?
The EP20K100QC208-1N operates from a 2.5 V core supply (VCCINT) with an allowed range of 2.375 V to 2.625 V. Its I/O ring (VCCIO) is multi-voltage and can be configured for 2.5 V, 3.3 V, or 5 V interfaces on a per-bank basis, enabling direct connection to legacy 5 V TTL buses without external level shifters.
Is the EP20K100QC208-1N still in production?
No, the EP20K100QC208-1N is not recommended for new designs (NRND) and the APEX 20K family is generally classified as mature with limited supply. According to distributor listings on DigiKey and Jotrin, remaining stock is sold on a last-time-buy basis. Intel recommends the Cyclone series for new designs.
Where can I download the EP20K100QC208-1N datasheet?
The official Altera APEX 20K datasheet is hosted at https://www.altera.com/literature/ds/apex.pdf and covers the EP20K100 family including the -1 speed grade and the QC208 PQFP pinout. For package-specific mechanical drawings, refer to Altera's Package Information document. The datasheet supersedes earlier 1999-era revisions and includes DC/AC specifications and configuration schematics.
What is the EP20K100QC208-1N pinout?
The pinout for the 208-pin PQFP package is defined in the APEX 20K datasheet's 'Pin-Outs for the EP20K100' section. Because pin functions depend on the user's Quartus II / MAX+PLUS II design assignment, refer to the compiled pinout report in your project rather than hard-coding positions. The PQFP-208 package has a 0.5 mm terminal pitch and gull-wing leads.
What is the maximum operating frequency of the EP20K100QC208-1N?
The APEX 20K family supports internal operation up to 250 MHz in the -1 speed grade per Altera's datasheet. In practice, the achievable system clock depends on routing congestion, logic depth, and I/O standard; expect 100–180 MHz in typical 16-bit datapath designs compiled with Quartus II. The four dedicated fast inputs feed the on-chip PLL for clock multiplication.
How does the EP20K100QC208-1N compare to the EP20K100EQC208-1X?
The EP20K100QC208-1N uses the original APEX 20K architecture while the EP20K100EQC208-1X is the APEX 20KE variant, which adds enhanced ESBs and a 0.15 µm copper-interconnect process. Both share the 208-pin PQFP pinout, so they are drop-in package-compatible. The 'E' device typically delivers 35% higher performance at the same speed grade.
What is the price of the EP20K100QC208-1N as of 2026-09-07?
The unit price of the EP20K100QC208-1N ranges from approximately $78.50 at qty-1 to $51.00 at qty-1,000 as of 2026-09-07, based on distributor listings. Because the part is NRND, prices fluctuate with remaining stock; for current quotes, contact XAIPART or check Mouser, DigiKey, and Microchip USA. Expect higher pricing for small-quantity spot buys.
Can the EP20K100QC208-1N be used in 5 V systems?
Yes, the EP20K100QC208-1N's I/O banks support 5 V VCCIO, allowing direct connection to 5 V TTL peripherals on a per-bank basis. The 2.5 V core must still be regulated separately from a 5 V rail. According to Altera's datasheet, 5 V tolerance is provided by the I/O cell design without requiring external clamping diodes, but always verify signal integrity at the chosen toggle rate.
What is the best drop-in replacement for the EP20K100QC208-1N?
The closest drop-in replacement is the EP20K100EQC208-1X (APEX 20KE variant) in the same 208-pin PQFP package, offering ~35% higher speed. For modern replacements, the Intel Cyclone EP1C6Q240C6 or EP1C12Q240C8 provide higher density in a different (240-pin PQFP) package, requiring PCB rework. Always validate timing closure when migrating families.
Is the EP20K100QC208-1N RoHS compliant?
The '-N' suffix in EP20K100QC208-1N denotes a lead-free (Pb-free) package per Altera's nomenclature convention, indicating RoHS compliance. The original APEX 20K family launched before RoHS, but later production runs and '-N' suffixes were converted to lead-free finishes. Confirm the RoHS certificate of compliance with your distributor for the specific date code shipped.
What is the difference between APEX 20K and APEX 20KE?
APEX 20KE is the second-generation revision of the APEX 20K family, fabricated on a 0.15 µm all-layer copper-metal process versus the original 0.22 µm process. Per Altera, 20KE delivers up to 35% faster design performance and improved power characteristics. The 'E' is identified in the part number (e.g., EP20K100E versus EP20K100); both share pin-compatible packages.
What are the key specifications of EP20K100QC208-1N that engineers should know?
The EP20K100QC208-1N integrates 100K typical gates, 4,160 logic elements, 26 ESBs, and 159 user I/Os in a 208-pin PQFP package. It runs on a 2.5 V core with multi-voltage I/O support for 2.5/3.3/5 V, achieves a 1.6 ns propagation delay, and supports up to 250 MHz internal operation. JTAG-based in-system programming and four dedicated fast inputs round out the silicon; the part is NRND.

选型指南
Choose the EP20K100QC208-1N when you need a lead-free APEX 20K device in a hand-solderable PQFP-208 for legacy designs or 5 V-tolerant glue-logic consolidation. If you can stay with non-Pb-free assemblies and want bitstream interchangeability, use EP20K100QC208-1 (no -N) at slightly lower cost. For higher performance on the same board, migrate to the APEX 20KE EP20K100EQC208-1X drop-in — same PQFP-208 pinout, 35% faster, recompiled bitstream required. For non-time-critical applications, EP20K100EQC208-3N offers the lowest price among -N-compliant 20KE options. Avoid the device only if you need >250 MHz logic or >159 I/Os; in that case, consider the EP20K100FC324-1 BGA-324 variant of the same silicon. For new designs, Intel recommends the Cyclone series.

设计说明
The EP20K100QC208-1N requires a 2.5 V core supply (VCCINT) and a separate VCCIO rail configurable to 2.5 V, 3.3 V, or 5 V per bank. Decouple each VCCINT pin with a 0.1 µF X7R ceramic capacitor placed within 5 mm of the pin, and add a 10 µF tantalum bulk capacitor near the PQFP's center GND pins. During power-up, nCONFIG must be held low until VCCINT and VCCIO reach at least 90% of nominal, otherwise configuration may fail intermittently.
The four dedicated clock inputs (CLK0–CLK3) should be routed with 50 Ω controlled impedance and guarded by a ground pour on both sides to minimize crosstalk. Because the PQFP-208 has 0.5 mm lead pitch, use 0.20–0.25 mm trace width and a 0.30–0.40 mm pad; IPC-7351 land patterns are recommended. Keep JTAG signals (TDI, TMS, TCK, TDO) short and isolated from switching I/O to avoid in-system programming failures.
Do not mix 5 V and 3.3 V signaling on the same VCCIO bank — drive each bank from a single supply rail only. Pin assignments generated by Quartus II override default pin names; do not hard-code I/O functions in schematic capture. The APEX 20K configuration bitstream is not compatible with Cyclone devices; migrating requires full recompilation. Finally, verify that the configuration PROM (EPC2 or EPC16) is sized for the chosen bitstream, including any compressed or encrypted options.
