EP1K50QC208-3 - ACEX 1K FPGA 50K Gates 208-PQFP | Altera
MPN: EP1K50QC208-3 ✗ Cuối đờiEP1K50QC208-3 Tóm tắt
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.

Ứng dụng tiêu biểu
EP1K50QC208-3 phù hợp cho 6 Áp dụngs: Telecommunications Line-Card Glue Logic, Industrial Control and Factory Automation, Legacy PCI Bus Interface Bridging, Test and Measurement Instrumentation Front-End, Aerospace and Defense Legacy Sustainment, ASIC Prototype and Pre-Production Emulation.
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.
Được đề xuất
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.
Được đề xuất
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.
Được đề xuất
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.
Được đề xuất
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.
Được đề xuất
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.

Ghi chú thiết kế
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.
Thông tin tuân thủ
Compliance status not explicitly stated in the verified web data. The ACEX 1K family predates widespread RoHS adoption; the -3N suffix variant is lead-free per Altera's part numbering convention. Engineers should verify compliance with their authorized distributor.
