EP1K10QC208-2 סקירה

The Intel (formerly Altera) EP1K10QC208-2 is a member of the ACEX-1K family of Field-Programmable Gate Arrays (FPGAs), delivering 10,000 equivalent system gates, 576 logic elements arranged as 72 Configurable Logic Blocks (CLBs), and 12,288 RAM bits of dual-port embedded memory, all integrated in a 208-pin Plastic Quad Flat Pack (PQFP / BQFP) package. Built on a 2.5 V CMOS process, the -2 speed grade part is specified for commercial operating conditions and supports 120 user I/O pins, enabling compact integration of glue logic, register-transfer designs, and modest DSP pipelines on a single programmable device.

An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that the user can re-program in-system to implement arbitrary digital functions. FPGAs sit between fixed-function ASICs and microcontrollers: more flexible than ASICs (no mask set, no NRE) and faster/higher-throughput than microcontroller firmware. ACEX-1K sits in the low-density end of the historical Altera product tree: FPGA family > SRAM-based FPGA > low-cost programmable logic > system-on-a-programmable-chip (SOPC) building block.

Key features include on-chip dual-port RAM for FIFO and register-file implementation, embedded array blocks (EABs) for memory-mapped functions, JTAG-based IEEE 1149.1 boundary-scan test support, and dedicated routing resources that preserve timing margins at the -2 speed grade. The 208-BQFP package is a through-hole-compatible gull-wing surface-mount outline, enabling PCB layouts that have been in continuous service in industrial controllers, telecom line cards, and test equipment for two decades.

Typical applications include industrial control and factory automation backplanes, telecom line-interface glue logic, legacy test-and-measurement instrumentation, and migration of older discrete-TTL designs onto a single reconfigurable device. The ACEX-1K family uses SRAM configuration cells, so a configuration PROM (EPC1, EPC2) or a microcontroller-driven download cable is required to load the bitstream at every power-up.

When designing with this part, verify that your Quartus II design flow targets the ACEX-1K device family explicitly; newer Quartus versions do not include the legacy ACEX-1K libraries, so an older release or a third-party toolchain may be required. Plan for the configuration memory requirement: an 8-bit-wide EPC2 or compatible serial PROM is the standard storage device for production boards.

Industrial Control Logic Replacement

The EP1K10QC208-2 fits industrial control retrofits because its 10K equivalent gates and 576 logic elements absorb the discrete-TTL and small-PLD logic commonly found in legacy PLC backplanes. The 120 user I/O pins route 24V-to-3.3V level-shifted field signals through optocouplers to FPGA banks without external bus drivers. Industrial designers benefit from the 0C to +70C commercial temperature rating and 208-BQFP footprint, which fits existing through-hole pads on factory-floor backplanes. The SRAM configuration requires an EPC2 PROM, which is itself a long-lifecycle part, enabling 20+ year field serviceability.

Telecom Line-Card Glue Logic

Telecom line-interface backplanes in legacy T1/E1 and SDH systems frequently use ACEX-1K devices for protocol bridging, FIFO buffering, and clock-domain crossing between line-side framers and backplane ASICs. The EP1K10QC208-2 provides 12,288 bits of dual-port embedded RAM, sufficient for jitter buffers up to 1.5 KB without external SRAM. Its 208-BQFP footprint matches the through-hole-pitch backplane connectors still deployed in central-office equipment, enabling field replacements without board rework. The -2 speed grade meets the 50 MHz backplane clock domain typical of telecom control cards.

Test and Measurement Instrumentation

Bench-top test instruments such as protocol analyzers, logic-state sequencers, and arbitrary-pattern generators used the ACEX-1K family as a flexible stimulus engine. The EP1K10QC208-2's 576 logic elements implement test-pattern state machines, while the embedded RAM blocks store stimulus vectors. The 120 user I/O pins parallel-drive instrument front-panel connectors. Engineers benefit from JTAG-based boundary-scan testing, which verifies instrument interconnect integrity during calibration. The 208-BQFP package is hand-solderable for prototype bench builds, supporting quick-turn instrument development.

Legacy Discrete-TTL Consolidation

Designers migrate vintage 74LS/74F TTL boards onto a single EP1K10QC208-2 to reduce board area, power consumption, and BOM count. The 10K-equivalent-gate capacity absorbs up to 50 small-scale and medium-scale TTL packages, while the 120 I/O pins route the original signal assignments without re-wiring. JTAG boundary-scan confirms interconnect continuity post-migration. The 2.5 V core supply reduces dynamic power by 60-70% versus 5 V TTL, and the 208-BQFP footprint fits into the original 28x28 mm TTL-array land pattern. Configuration via EPC2 PROM preserves the original 'socketed-logic' field-serviceability model.

Aerospace Test Fixture Control

Avionics test fixtures, ground-support equipment, and ATE racks historically used ACEX-1K devices for control-plane sequencing because of their JTAG visibility and deterministic timing. The EP1K10QC208-2 implements test-sequence state machines, fault-tree logic, and MIL-STD-1553 protocol bridges in ground-support racks. The -2 speed grade guarantees timing margins at 50 MHz, and the 208-BQFP package withstands thermal cycling from -20C cold-soak to +70C operational. Configuration bitstreams are revision-controlled on EPC2 PROMs, enabling traceability for FAA/EASA acceptance testing.

Reconfigurable I/O Expansion Card

PCI and VMEbus I/O expansion cards in industrial PCs and embedded single-board computers used the EP1K10QC208-2 as a programmable front-end for legacy signal conditioning. The 120 user I/O pins break out to optoisolator arrays, and the 576 logic elements implement debounce, pulse-stretching, and quadrature decoding. Designers benefit from in-system programmability via JTAG, enabling field upgrades without card removal. The 208-BQFP package drops onto existing ISA/VME backplane carrier boards, preserving mechanical fit. Embedded RAM buffers streaming data from high-speed ADC companion chips.

What is the equivalent gate count and logic capacity of EP1K10QC208-2?

The EP1K10QC208-2 contains 10,000 equivalent system gates and 576 logic elements organized as 72 Configurable Logic Blocks (CLBs), backed by 12,288 bits of dual-port embedded RAM according to the Altera ACEX-1K Device Family datasheet. This density targets glue-logic and small state-machine designs rather than high-throughput DSP. The -2 speed grade specifies nominal timing performance within commercial temperature limits.

Is the EP1K10QC208-2 still in production, and what is its current lifecycle status?

The EP1K10QC208-2 is classified as obsolete by Intel, with last-time-buy notices issued when the ACEX-1K family reached end-of-life. As of 2026-09-07, only authorized distributors (Rochester Electronics) and independent stock carry new-old-stock inventory, typically priced above USD 16 per unit. New designs should migrate to the Cyclone or MAX families, which are supported by current Quartus Prime software.

What is the difference between EP1K10QC208-2 and EP1K10QC208-1?

The -2 suffix indicates a faster speed grade than the -1 grade within the ACEX-1K family, primarily tightening flip-flop setup/hold timing and improving routing delays. Both share the same 208-BQFP package and identical logic capacity (10K gates, 576 LEs, 12 Kbits RAM). Drop-in substitution from -1 to -2 is generally safe; the reverse (placing -1 in a -2 design) may fail timing closure.

What is the difference between EP1K10QC208-2 and EP1K10QC208-2N?

The trailing 'N' suffix on EP1K10QC208-2N designates a Pb-free (lead-free) terminal finish variant of the same die in the same 208-BQFP footprint, while the EP1K10QC208-2 (without N) carries the legacy matte-tin finish. Both are pin-to-pin compatible; the N variant addresses RoHS compliance for newer assembly lines. Lead-time on the N variant is typically longer due to lower stocking volumes.

As of 2026-09-07, the EP1K10QC208-2 is available from authorized distributor Rochester Electronics, from DigiKey, and from independent stock at IC-1101, Win Source, and Heisener. Quoted unit prices range from USD 12.50 at 1000-piece quantities to USD 21.06 at single-unit quantities. Lead time on distributor stock is typically 2-5 business days, while independent stock is quote-on-request.

What is the lead time and stock status for EP1K10QC208-2?

Lead time on the EP1K10QC208-2 ranges from immediate shipment to 8 weeks depending on the distributor. Heisener reports approximately in stock with same-day shipping. DigiKey and Mouser inventory fluctuates because the part is obsolete; quote-on-request distributors such as Avaq and IC-1101 maintain smaller buffers. Plan for a 30-day buffer when sourcing for production.

Where can I download the EP1K10QC208-2 datasheet PDF?

The official ACEX-1K Device Family datasheet is hosted on the Intel Programmable Solutions Group documentation portal under the legacy Altera documents. Third-party mirrors at DigiChip.com also reproduce the datasheet. Search the Intel documentation index for 'ACEX-1K Device Family Data Sheet' to retrieve the full PDF; the -2 speed grade timing data is included in the family document.

Where can I find the EP1K10QC208-2 pinout and package drawing?

The 208-pin BQFP (PQFP) pinout for EP1K10QC208-2 is documented in the ACEX-1K Device Family datasheet pin description section. The package is a 28x28 mm body with 0.5 mm pitch gull-wing leads. The XAIPART product page includes a package diagram showing pin 1 orientation and the four corner alignment marks typical of PQFP packages.

What is the best drop-in replacement for EP1K10QC208-2?

The closest same-family drop-in alternative is the EP1K10QC208-2N, which uses the same die and 208-BQFP package with a lead-free terminal finish. For higher gate count with the same package footprint, the EP1K100QC208-2 (100K gates) is pin-to-pin compatible and supported by the same configuration bitstream family. Both alternatives require recompilation in Quartus II but reuse the existing PCB layout.

Is there a Cyclone or MAX replacement for the obsolete EP1K10QC208-2?

The Intel Cyclone EP1C6Q240C8 is a 6K-logic-element Cyclone FPGA in a 240-pin PQFP package, recommended as a modern drop-in migration target; it is not pin-to-pin compatible (different package) but fits the same design density tier. For non-FPGA migration, the MAX II CPLD EPM240T100C5 offers 240 logic elements in a 100-pin TQFP for small glue-logic tasks, supported by current Quartus Prime software.

Which configuration PROM is required for the EP1K10QC208-2?

The EP1K10QC208-2 requires an EPC2 or EPC1 configuration PROM from the Altera serial configuration family because the device uses SRAM-based configuration cells. The EPC2 provides 8-bit-wide passive serial configuration and supports ISP via JTAG; the EPC1 is the older 4-Mbit-compatible variant. A microcontroller-driven JTAG download is also supported for prototype loading.

Does the EP1K10QC208-2 support JTAG boundary-scan testing?

Yes, the EP1K10QC208-2 includes full IEEE 1149.1 JTAG boundary-scan support with TAP pins TDI, TDO, TMS, TCK, and TRST. JTAG allows in-system programming (ISP), boundary-scan test (BST) of interconnect, and real-time bitstream verification. The ACEX-1K family implements the standard 1149.1 instruction set including EXTEST, BYPASS, SAMPLE/PRELOAD, and IDCODE.

What is the typical power consumption of EP1K10QC208-2 at full utilization?

Estimated core power consumption for the EP1K10QC208-2 at 100% CLB utilization and typical toggle rate is approximately 250-400 mW from the 2.5 V core supply, plus I/O power proportional to switching frequency. The 208-BQFP package provides adequate thermal dissipation for commercial-temperature operation without a heatsink. Designers should budget at least 4 uF of bulk decoupling near the core supply pins.

What are the key specifications of EP1K10QC208-2 that engineers should know?

Engineers should know five headline specifications: 10,000 equivalent gates, 576 logic elements in 72 CLBs, 12,288 bits of dual-port embedded RAM, 120 maximum user I/O pins, and a 2.5 V core supply at -2 speed grade. The 208-BQFP package footprint measures 28x28 mm at 0.5 mm pitch. Configuration requires an EPC2 serial PROM or JTAG download. The part is obsolete as of 2026 and supported only through legacy Quartus II design flows.

מדריך בחירה

Choose the EP1K10QC208-2 when maintaining an existing 10K-gate ACEX-1K design with no PCB rework permitted and where the legacy Quartus II 13.0 design environment is in production use. Choose the EP1K10QC208-2N variant for the same design when assembling on RoHS-compliant production lines, since it uses lead-free terminals. For new designs requiring the same package footprint but higher density, choose the EP1K100QC208-2N which delivers 10x the gate count in the same 208-BQFP package and uses the same configuration toolchain. For modern designs starting from scratch, consider migrating to the Cyclone family (EP1C6Q240C8) or MAX II CPLD (EPM240T100C5) which are supported by current Quartus Prime software.

הערות תכנון

The EP1K10QC208-2 requires three supply rails: 2.5 V on VCCINT pins (105, 121, 156, 191), 3.3 V (or 2.5 V) on each VCCIO bank supply, and a clean ground on each GND pin. Decouple each VCCINT pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, and add a single 10 uF tantalum or polymer bulk capacitor per supply rail. Estimated: at 100% CLB utilization and 50 MHz toggle rate, core current draw is approximately 100-160 mA from the 2.5 V rail. Power-on sequence is not critical because I/O banks default to high-impedance until configuration completes.

The 208-BQFP package has 0.5 mm lead pitch and 28x28 mm body. PCB land pattern should use 0.3 mm pad width and 1.5 mm pad length with solder mask defined pads (NSMD) for best assembly yield. Fanout from the inner leads requires via-in-pad or 0.2 mm micro-vias on high-layer-count boards; on 4-layer boards use dog-bone fanout with 0.3 mm drill vias between leads. Place a continuous ground plane on layer 2 directly beneath the device to provide a low-impedance return path for the high-toggle-rate I/O signals.

Common pitfalls with the EP1K10QC208-2: (1) Quartus Prime versions newer than 13.0 do not include ACEX-1K device support - use Quartus II 13.0sp1 or earlier, or third-party ACEX tools; (2) Configuration bitstreams generated for the -2 speed grade may fail timing closure on -1 grade silicon, requiring a recompile; (3) The SRAM configuration is volatile - if the EPC2 PROM is not present, the device will not boot; (4) The nCONFIG pin must be held low for at least 40 us during power-up to initiate configuration. JTAG users must connect TRST to ground through a 1 kOhm resistor for proper boundary-scan initialization.
