EP1K50QC208-3 개요

The Altera EP1K50QC208-3 is a member of the ACEX 1K programmable logic family, integrating 50,000 typical gates, 2,880 logic cells, and 40,960 RAM bits into a single 208-pin PQFP package. It is a 2.5 V SRAM-based field-programmable gate array (FPGA) built on a 0.22 µm CMOS process, offering a maximum internal operating frequency of 166.67 MHz with a -3 speed grade. According to the Altera ACEX 1K datasheet family data sheet, the device provides 360 Logic Array Blocks (LABs), 147 user I/O pins, and 12 Embedded Array Blocks (EABs) for dual-port memory and megafunction implementation.

A Field Programmable Gate Array (FPGA) is a programmable logic device (PLD) that combines configurable logic blocks, programmable interconnects, and dedicated memory resources on a single die. Within the integrated-circuit taxonomy, an FPGA sits under programmable logic devices, then semiconductor ICs, and finally integrated circuits. FPGAs are used to implement arbitrary digital logic, signal-processing pipelines, and glue logic that would otherwise require multiple discrete components, while remaining re-programmable in-system to fix bugs or upgrade functionality.

The EP1K50QC208-3's defining features include die-efficient LUT-based logic combined with EAB memory blocks for efficient implementation of RAM, ROM, and specialized megafunctions such as multipliers and FIFO controllers. The device supports in-system configuration via passive serial, active serial, and JTAG modes, and is supported by the Quartus II and MAX+PLUS II design toolchains. The PQFP-208 package supports surface-mount assembly with 147 usable I/Os, sufficient for multi-bus glue-logic and mid-density digital control applications.

The architecture is built around LABs containing 8 Logic Elements (LEs) each, with each LE containing a 4-input LUT, a programmable register, and a carry chain. The EABs provide 4 Kbit memory blocks, configurable as single- or dual-port RAM, ROM, or as look-up-table based logic. The device operates from a 2.5 V core supply with separate VCCIO banks for output voltage flexibility, and exposes multi-voltage I/O standards including LVTTL, LVCMOS, and PCI.

Typical applications include telecommunications line-card glue logic, industrial control systems, test and measurement instrumentation front-ends, and legacy PCI bus interface bridging. The ACEX 1K family was positioned as a low-cost, low-power programmable alternative to ASICs for mid-volume products, and remains in service in long-lifecycle industrial and aerospace programs that have completed extensive design qualification.

When designing with this part, note that the ACEX 1K family has been discontinued by Intel (formerly Altera) and is designated Not Recommended for New Designs. Engineers should validate long-term supply, use authorized-franchise distributors for current production runs, and consider Cyclone II/III/IV or MAX II CPLDs for new designs of similar density.

🌐

Telecommunications Line-Card Glue Logic

The Altera EP1K50QC208-3 fits telecommunications line-card glue-logic applications because its 50K gates and 12 EABs provide ample density for bus-bridging, FIFO buffering, and protocol-interfacing functions between TDM framers, network processors, and backplane SERDES. With 147 user I/Os in a PQFP-208 package, the device can replace multiple discrete 74-series TTL packages and small CPLDs with a single re-programmable part. The 166.67 MHz internal frequency supports 155 Mbps telecom paths, while 2.5 V core with separate VCCIO banks enables mixed 3.3 V/5 V interfacing to legacy line-card ASICs. Compared to a discrete-TTL implementation, the EP1K50QC208-3 reduces board area by 70%, simplifies ECO work via in-system JTAG reconfiguration, and accelerates time-to-market.

🏭

Industrial Control and Factory Automation

The EP1K50QC208-3 is well-suited for industrial control applications including PLC backplanes, motor-control signal conditioning, and encoder-interfacing logic. Its 2.5 V core with multi-voltage I/O banks (LVTTL, LVCMOS, PCI) supports direct connection to 3.3 V or 5 V industrial peripherals without level shifters. The 12 EABs provide 4-Kbit dual-port memory blocks for implementing high-speed position-capture FIFOs and quadrature-decoder buffers. The PQFP-208 package's surface-mount compatibility simplifies automated assembly in volume production. The -3 speed grade delivers 166.67 MHz internal frequency, sufficient for sub-microsecond servo-loop control updates in stepper and BLDC motor controllers.

🖥️

Legacy PCI Bus Interface Bridging

The EP1K50QC208-3 supports legacy 32-bit/33 MHz PCI bus interface bridging, where the device implements master/target state machines, configuration-space registers, and FIFO interfaces to a local bus or backplane. The 2,880 logic cells are sufficient to encode the full PCI specification with parity and bus-arbitration logic. The 147 user I/Os allow direct interfacing to 32-bit PCI address/data plus control signals, JTAG, and the local bus without external transceivers. The 12 EABs provide target-memory FIFOs for posted-write and read-prefetch buffers. The device's 2.5 V core with 3.3 V PCI-compliant I/Os meets the original PCI Local Bus Specification electrical requirements.

🔧

Test and Measurement Instrumentation Front-End

The EP1K50QC208-3 fits test and measurement front-end designs where the FPGA implements timing generators, pattern sequencers, and data-format conversion between analog front-ends and DSP processors. Its 12 EABs function as deep capture buffers for sampled-data acquisition, while 147 I/Os allow multi-channel parallel ADC/DAC interfacing at full speed. The 166.67 MHz internal frequency supports 100 MHz+ pattern-generation clocks required by ATE testers and oscilloscope subsystems. The PQFP-208 package's robust thermal and mechanical characteristics suit lab-instrument enclosures, and JTAG-based reconfiguration enables field firmware updates on deployed test sets.

✈️

Aerospace and Defense Legacy Sustainment

The EP1K50QC208-3 remains in service across aerospace and defense programs that completed extensive qualification and certification cycles. Long-lifecycle platforms (military radios, avionics, and surveillance systems) often require sustaining original FPGA parts for 15-25 years to avoid re-certification costs. The ACEX 1K family is authorized for use under these legacy programs due to known-good silicon, mature design tool chains, and existing FPGA bitstream IP libraries. Authorized-franchise distributors maintain controlled stock for these programs. Engineers in this segment verify date code, lot traceability, and perform upscreening to source-control drawings before installation.

💡

ASIC Prototype and Pre-Production Emulation

The EP1K50QC208-3 is commonly used for ASIC prototyping and pre-production emulation where designers map gate-level netlists to FPGA to validate functionality before silicon spin. Its 50K-gate capacity accommodates mid-complexity ASICs, and the 2,880 logic cells provide enough LUTs to implement custom state machines, register files, and small on-chip memories via EABs. The PQFP-208 package supports standard JTAG-based debugging and in-system reprogramming for rapid design iteration. Quartus II and MAX+PLUS II design flows allow direct synthesis from VHDL or Verilog, and the 166.67 MHz operation validates ASIC timing under realistic clock loads.

What is the lead time for EP1K50QC208-3?
Lead time for the obsolete EP1K50QC208-3 typically ranges from 6 to 16 weeks depending on distributor inventory. Because the ACEX 1K family is no longer manufactured, lead times extend significantly when existing stock depletes. Engineers are advised to confirm lead time with their distributor before committing to a redesign.
EP1K50QC208-3 vs EP1K100QC208-3 — which is better for high-density logic?
The EP1K100QC208-3 contains 100,000 typical gates versus 50,000 in the EP1K50QC208-3, doubling logic capacity in the same PQFP-208 package. Choose EP1K100QC208-3 when your design exceeds the EP1K50's 2,880-cell ceiling; otherwise the EP1K50 is more cost-efficient for mid-density glue logic.
Is EP1K50QC208-3 suitable for new product designs in 2026?
No, EP1K50QC208-3 is not recommended for new product designs as of 2026. The ACEX 1K family has reached end-of-life. For new designs requiring similar density, Intel recommends Cyclone II/III/IV families, or MAX II/IV/V CPLDs for lower logic counts. The EP1K50 should only be used for sustaining legacy production.
What is the best drop-in replacement for EP1K50QC208-3?
The best drop-in replacement is the EP1K50QC208-2 or EP1K50QC208-2N, which share the same 208-pin PQFP package and identical die but offer a slightly lower speed grade. For lead-free requirements, the EP1K50QC208-3N is a direct drop-in equivalent with identical electrical specifications.
Can EP1K30QC208-3 replace EP1K50QC208-3?
The EP1K30QC208-3 shares the same 208-pin PQFP package but only contains 30,000 typical gates versus the EP1K50QC208-3's 50,000. It is pin-compatible in the package but is NOT a functional drop-in because designs targeting 50K-gate utilization will not fit. Use EP1K100QC208-3 instead if upward migration is needed.
Where can I download the EP1K50QC208-3 datasheet PDF?
The EP1K50QC208-3 datasheet PDF is available from multiple sources including the Intel/Altera ACEX 1K family data sheet at alterasemi.com, all-data-sheet aggregators, and distributor product pages. The family data sheet covers electrical specifications, pinout, configuration modes, and thermal characteristics for all ACEX 1K devices.
Where can I find the EP1K50QC208-3 pinout?
The EP1K50QC208-3 pinout is documented in the ACEX 1K Programmable Logic Device Family data sheet on page sections covering the PQFP-208 package. Pin assignments are organized by I/O bank, JTAG signals, configuration pins, and dedicated clock/clear inputs. Reference designators are printed on the package top view.

선택 가이드

Choose EP1K50QC208-3 when you need a mid-density 2.5 V FPGA in a PQFP-208 package at the highest -3 speed grade for telecom line cards, industrial control, or legacy PCI bridging. Choose EP1K50QC208-2N if Pb-free compliance is required and -2 speed grade is acceptable for your timing budget. Choose EP1K100QC208-3 when design utilization exceeds 2,880 cells and you need an upward migration path in the same PCB footprint. Avoid ACEX 1K for any new design — for greenfield projects select Cyclone IV/V or MAX V CPLDs from the active Intel FPGA portfolio. Always purchase from authorized-franchise distributors given the obsolete status.

설계 노트

Estimated: The EP1K50QC208-3 core supply VCCINT requires a 2.5 V regulator with at least 500 mA capability under typical operating conditions. Multiple VCCINT pins (located at pins 7, 33, 63, 93, 123, 153, 183 per the PQFP-208 layout) must each be decoupled with 0.1 µF ceramic capacitors placed within 5 mm of the pin. VCCIO pins should be tied to 3.3 V for LVTTL/LVCMOS operation, or 5 V only if the specific I/O bank is rated for 5 V tolerant input — verify in the ACEX 1K family data sheet before connecting 5 V signals.

The PQFP-208 package has a 0.5 mm lead pitch and a body size of approximately 28 mm × 28 mm, which demands a 4-layer PCB with continuous power and ground planes beneath the device. Maintain at least 8 mil trace widths for I/O signals and use 4-via stitching for ground returns around the device perimeter. JTAG signals (TCK, TMS, TDI, TDO) should be routed as a group with matched lengths within 1 inch to avoid configuration timing violations.

Configuration mode selection must be hard-wired via MSEL pins (typically tied high or low via 10 kΩ resistors) to select passive serial, active serial, or JTAG configuration at power-up. Floating MSEL pins are a common board bring-up failure. Also note that the ACEX 1K family is NOT 5 V tolerant on VCCIO unless explicitly stated — connecting 5 V signals to VCCIO = 3.3 V banks will damage the I/O cells. Always cross-reference the I/O standard table in the family data sheet.
