EP1K30QC208-2 概要
An FPGA is an integrated circuit whose logic fabric can be reprogrammed after manufacturing to implement arbitrary digital logic functions. In a typical system hierarchy, an FPGA is a programmable logic device, one subclass of integrated circuits, and the EP1K30 is a member of Altera's ACEX 1K family. ACEX 1K was positioned for low-cost system-on-a-programmable-chip (SOPC) integration, combining logic array blocks (LABs) with an enhanced embedded array that can implement memory and specialized logic functions. The QC208 version is a 208-lead plastic quad flat package with gull-wing terminals and a square body, commonly used on boards that do not need the density of a ball-grid array.
Key features of this -2 speed-grade part include 216 LABs, 1,728 logic elements, 24,576 RAM bits, 147 user I/O pins, and 6 dedicated inputs. The 2.5 V CMOS architecture keeps core power low for its era, while the 208-terminal form factor provides ample routing access for moderate pin-count designs. The commercial operating range is 0 C to 70 C, which suits equipment installed indoors in industrial, communications, or instrumentation environments. The -2 speed grade sits between faster -1 and slower -3 family options, giving designers a balanced timing-versus-cost choice.
Technically, the EP1K30QC208-2 is an SRAM-based FPGA: its configuration is loaded at power-up and is lost when power is removed unless an external configuration device or JTAG host is used. The ACEX 1K embedded array in the family datasheet literature supports dual-port RAM and specialized logic megafunctions, which helps designers implement FIFOs, small buffers, and state machines without external memory devices. Within the ACEX 1K hierarchy, the EP1K30 offers mid-density resources and is often paired with companion ACEX devices when a design must be migrated to a smaller or larger density.
Typical applications include industrial controller glue logic, communication interface buffering, video timing and imaging logic, test-and-measurement data formatting, and legacy board repair. In each of these, the available I/O and internal RAM reduce the number of external logic and FIFO chips. The 2.5 V core rail should be generated from a clean low-noise supply, and I/O voltage levels should be checked before connecting to 3.3 V or 5 V peripherals.
A key design consideration is the configuration source. Because ACEX 1K does not retain its program when unpowered, the PCB should include a configuration device or provide JTAG access so the FPGA can be reprogrammed at every power-up. For thermal and mechanical design, the 208-pin PQFP has a 0.5 mm terminal pitch; use a well-ventilated layout and follow the package land pattern.
This page synthesizes distributor pricing, available package-compatible alternatives, and practical design guidance not found in the manufacturer datasheet alone. It is intended to help engineers quickly evaluate EP1K30QC208-2 for legacy BOM replacement, reverse engineering, and maintenance of ACEX 1K-based systems.

主な用途
EP1K30QC208-2 の用途: 6 件s: Industrial Control and Automation, Communication Interface Buffering, Video and Display Timing Logic, System-on-a-Programmable-Chip Prototyping, Legacy Board Repair and Replacement, Test and Measurement Instrumentation.
Industrial Control and Automation
The Altera EP1K30QC208-2 suits compact industrial controllers because its 147 user I/O pins can directly capture limit switches, quadrature encoders, and basic motor-drive signals without an additional CPLD. With 1,728 logic elements and 24,576 RAM bits, it can implement a soft UART, small state machines, and glue logic in one 2.5 V device. The commercial 0 C to 70 C range covers panel-mounted equipment in conditioned enclosures, but not extreme cold. In this role, the -2 speed grade balances cost and processing headroom; if the servo loop drives faster parallel buses, test the -1N speed grade before committing to production. For power, keep the 2.5 V core clean and add separate I/O supply regulation if mixing 3.3 V or 5 V input thresholds through level shifters.
おすすめ
Communication Interface Buffering
EP1K30QC208-2 can implement small FIFOs, packet buffers, and protocol glue in communication equipment because its embedded array contains 24,576 RAM bits and its 147 I/O can connect to legacy parallel buses, UARTs, or PHY devices. In this architecture, the FPGA reduces external FIFO and logic IC count. The 208-pin PQFP package is easier to route on prototype boards than a dense BGA. Because the core is 2.5 V, voltage-level matching is required when connecting directly to 3.3 V Ethernet or serial PHYs. Timing should be checked if the link clock exceeds the -2 speed-grade capability. The -1N variant is useful when the data path has narrow setup/hold margin after PCB trace propagation delay is included.
おすすめ
Video and Display Timing Logic
For video capture and display systems, EP1K30QC208-2 can integrate line counters, blanking generators, pixel-clock dividers, and register interfaces in a 30,000-gate ACEX 1K device. Its 147 user I/O pins can connect to 8-bit or 16-bit video data buses and horizontal/vertical synchronization signals. The 24,576 RAM bits can store small scan-line FIFOs or delay buffers used in timing alignment. The 0 C to 70 C commercial range fits TV-wall, medical-display, and industrial-monitor applications found in room-temperature environments. High-speed video clocks should be checked against ACEX 1K timing data; if 75 MHz pixel rates are required, use the -1N speed grade to obtain extra setup margin. Use proper series termination on video clock traces.
おすすめ
System-on-a-Programmable-Chip Prototyping
EP1K30QC208-2 provides usable logic and memory resources for low-cost SOPC prototyping in the ACEX 1K family. The embedded array supports RAM and specialized logic functions, making it possible to prototype memory-mapped peripherals, bus bridges, and control registers before migrating to an ASIC or a newer FPGA. The 208-pin PQFP allows easy probing of internal signals from the top side, which is valuable during debug. The 2.5 V core requires a local low-noise supply, often derived from a 3.3 V rail with an LDO regulator. The -2 speed grade is suitable for early architecture exploration; if the final prototype must run at the maximum system clock, resynthesize with -1N timing constraints and verify the design closes timing before board production.
おすすめ
Legacy Board Repair and Replacement
EP1K30QC208-2 is commonly requested for legacy board repair, spare-part production, and retrofitting installed ACEX 1K systems. Because the package is a 208-pin BFQFP/PQFP with a 0.5 mm pitch, the -1N, -1, -2N, -3N, and -3 EP1K30 variants are drop-in replacements on the same PCB footprint. A repair technician must confirm the original speed grade and configuration bitstream compatibility before substitution. The -2N variant provides the same speed grade as EP1K30QC208-2, while -1N/-1 add timing margin and -3N/-3 are slower grades. Since ACEX 1K is a mature family, purchase sufficient remaining inventory for the product service life and verify date code and lead finish against the assembly process.
おすすめ
Test and Measurement Instrumentation
EP1K30QC208-2 can perform channel sequencing, trigger conditioning, and data formatting in bench and industrial test instruments. Its 147 I/O pins are sufficient to connect to multiple ADC or DAC parallel ports, while the internal 24,576 RAM bits can be used as a small acquisition FIFO. The commercial temperature range is acceptable for laboratory and bench-top products. Because the PQFP package has no large center thermal pad, route multiple package ground pins directly to the PCB ground plane to manage simultaneous switching noise. For waveform timing applications, use an external low-noise 2.5 V regulator and place it close to the FPGA. If the sample clock is near the timing limit of the -2 grade, move to the -1N variant or a newer FPGA family.

設計ノート
The EP1K30QC208-2 requires a nominal 2.5 V core supply, but the verified source data lists an allowed range of 2.375 V to 2.625 V. Use a low-noise 2.5 V regulator or a clean DC-DC module with adequate decoupling. Place at least one 0.1 uF ceramic capacitor near each core power pin and a 10 uF bulk capacitor near the FPGA package. If the board also uses 3.3 V I/O rails, provide supply sequencing and ensure that no I/O pin forward-biases the FPGA ESD diodes when the core supply is unpowered.
ACEX 1K FPGAs are SRAM-based and lose their configuration when power is removed. The EP1K30QC208-2 is not a flash FPGA, so the PCB must provide an external configuration source such as an EPC configuration device or JTAG host. Hold nCONFIG low until all supply rails are stable, then release it to start configuration. Confirm that CONF_DONE and nSTATUS signals are pulled to the correct level and are monitored after power-up. If configuration fails, pulse nCONFIG low and retry; do not operate the FPGA with an unknown logic image.
The 208-pin BFQFP/PQFP package has a 0.5 mm terminal pitch and uses gull-wing leads. Follow the manufacturer land pattern for solder paste stencil opens and keep vias outside the pad area. Route sensitive configuration signals away from high-current switching outputs. For high-speed user I/O, keep traces short, matched, and impedance-controlled as required by the I/O standard. Because this package does not have a central thermal pad, connect multiple package ground leads to the ground plane to reduce loop inductance and help carry heat from the device.
コンプライアンス情報
The fetched web data does not provide explicit RoHS/REACH certificates for EP1K30QC208-2. The -N suffix variants in the ACEX 1K family are commonly associated with lead-free finish, but this should be verified against the specific date code and manufacturer compliance documentation before assembly.
