EP1K30QC208-2N - 30K Gate ACEX 1K FPGA, 208-PQFP | Intel

An FPGA (Field-Programmable Gate Array) is a programmable logic device (PLD) that combines the density of an ASIC with the flexibility of in-system reprogrammability. The ACEX 1K family specifically targets cost-sensitive glue-logic, bus-interface, and DSP-coprocessor applications. It sits within the broader hierarchy of programmable logic: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit (IC) -> semiconductor. Compared with CPLDs, FPGAs offer much higher logic density and embedded memory, at the cost of volatile configuration and slightly higher power.
Key features of the EP1K30QC208-2N include 147 user I/O pins, 216 logic array blocks (LABs), embedded dual-port RAM, a dedicated Double Data Rate (DDR) interface option, and an enhanced embedded array for implementing megafunctions such as efficient memory and specialized logic functions. The 208-pin PQFP package supports easy board-level assembly for prototype and low-to-mid volume production, while the 2.5 V core and multi-voltage I/O bank support simplify interfacing with 3.3 V and 5 V peripherals.
Architecturally, the EP1K30QC208-2N uses a Lookup-Table (LUT)-based logic element with 4-input combinational capability and a register, organized into LABs with carry-chain and cascade-chain interconnect. The 24 Kbit embedded system block (ESB) memory can be configured as dual-port RAM, ROM, FIFO or CAM, removing the need for external SRAM in many data-pipeline designs. Configuration is loaded from a serial PROM via the dedicated configuration interface.
Typical applications include glue logic between microprocessors and peripherals, custom bus bridges (PCI to local bus), DSP coprocessors, industrial control and instrumentation front-ends, telecommunications line cards, and legacy system refresh projects where a programmable replacement is preferred to an ASIC redesign. Designers often pair it with EPC2 configuration PROMs from Intel/Altera for standalone boot.
When designing with this device, ensure the 2.5 V VCCINT and VCCIO bank supplies are properly decoupled (one 0.1 µF and one 10 µF per pin group) and that the configuration clock and MSEL pins are set for the desired configuration mode (AS, PS or JTAG). Because ACEX 1K parts have been EOL for many years, engineers should verify long-term availability before committing the part to new designs.

典型應用
EP1K30QC208-2N 適用於 6 應用s: Industrial Glue Logic and Bus Interface, DSP Coprocessor for Embedded Systems, Telecommunications Line-Card Interface, Legacy System Refresh and Field Repair, Test and Measurement Front-End Logic, Custom Peripheral Controller for PC/Embedded Systems.
Industrial Glue Logic and Bus Interface
The EP1K30QC208-2N is widely used as a low-cost glue-logic device that bridges mismatched bus protocols (PCI to local bus, ISA to memory, custom parallel interfaces) on legacy industrial control boards. Its 1,728 logic elements and 24 Kbit of embedded dual-port memory are sufficient to implement medium-complexity state machines, FIFOs and address-decoding logic without external SRAM. The 208-pin PQFP package simplifies board rework and hand-soldering during field repairs, while 2.5 V core plus multi-bank I/O support allow direct interfacing with 3.3 V and 5 V peripherals. Engineers often pair the device with an EPC2 configuration PROM for autonomous boot on power-up, eliminating the need for a microcontroller bootloader.
推薦
DSP Coprocessor for Embedded Systems
With 200 MHz internal performance and 24 Kbit of embedded RAM, the EP1K30QC208-2N serves as a dedicated DSP coprocessor attached to a host microcontroller or DSP, accelerating FIR/IIR filters, FFT butterflies and motion-control loops in real time. The dual-port EAB allows simultaneous read/write access from the host CPU and the FPGA's internal datapath, enabling pipelined sample-by-sample processing at audio or low-MHz IF sample rates. Compared with a software DSP implementation, the FPGA off-loads deterministic processing from the host, freeing CPU cycles for system-level tasks and improving closed-loop latency.
推薦
Telecommunications Line-Card Interface
The EP1K30QC208-2N integrates framing, de-skew and channel-aggregation logic on legacy telecom line cards where a low-density, low-power FPGA is preferred to a full ASIC. Its 147 user I/Os connect to multiple serializers, framers and backplane transceivers without external bus muxing, while the embedded dual-port memory provides elastic buffering for rate adaptation between network domains. The 2.5 V core and 208-pin PQFP footprint remain attractive for telecom OEMs that standardized on ACEX 1K in the early 2000s and need an exact-form-factor replacement during repair or redesign.
推薦
Legacy System Refresh and Field Repair
Because the EP1K30QC208-2N is pin-compatible across speed grades (-1, -2, -3) and across the entire ACEX 1K 208-PQFP family, it is the preferred drop-in for repairing and refreshing long-life industrial equipment such as CNC controllers, railway signaling modules and medical imaging subsystems where the original ACEX 1K device is damaged or out of stock. Engineers can replace a failed EP1K30QC208-2N with an EP1K30QC208-3N (faster speed grade) without any PCB change, gaining extra timing margin in legacy designs.
推薦
Test and Measurement Front-End Logic
Bench-top test instruments (logic analyzers, protocol exercisers, ATE load boards) use the EP1K30QC208-2N to implement reconfigurable stimulus generators, pattern sequencers and timing engines that must adapt to multiple DUT interfaces. The FPGA's 147 user I/Os and 24 Kbit embedded memory allow complex multi-channel timing patterns to be generated without external logic, while the 208-pin PQFP allows easy rework when test programs are ported between platforms. Designers can reuse the same ACEX 1K bitstream across product variants by swapping pin assignments in the Quartus design software.
推薦
Custom Peripheral Controller for PC/Embedded Systems
Designers use the EP1K30QC208-2N as a single-chip peripheral controller on PC motherboards and embedded SBCs to provide custom parallel ports, proprietary interfaces or specialized I/O expansion that the host CPU cannot address directly. The FPGA implements register maps, interrupt controllers and DMA engines in 1,728 logic elements, while the dual-port EAB acts as a shared mailbox between the host bus and the FPGA's internal state machine. The 208-pin PQFP package and 147 I/O count fit easily on a standard ATX add-in card or COM Express carrier, and the 2.5 V core supports both 3.3 V and 5 V PCI-style slot signaling.

主要差異化特點
- Exact drop-in compatibility with all ACEX 1K speed grades in 208-PQFP (對比EP1K30TI144-2N)
- Pin-compatible higher-density upgrade path (對比EP1K100QC208-2N)
- Higher speed grade available in same package (對比EP1K30QC208-1N)
設計說明
Estimated: the EP1K30QC208-2N core draws approximately 30-50 mA at 2.5 V VCCINT plus bank-dependent I/O current during switching. Each VCCINT and VCCIO pin should be decoupled with a 0.1 µF ceramic capacitor placed within 5 mm of the pin, and a single 47-100 µF bulk capacitor should serve the entire 208-PQFP footprint. Because ACEX 1K is a SRAM-based FPGA, configuration is volatile - the VCCINT rail must remain stable during power-down to avoid partial reconfiguration.
The 208-pin PQFP package has 0.5 mm pitch gull-wing leads. Use a 4-layer PCB with continuous ground and power planes directly under the device to provide low-impedance return paths for the high-speed I/O signals. Route JTAG signals (TCK, TMS, TDI, TDO) as a daisy-chain with 10 kΩ pull-ups on TMS and TDI, and place the JTAG header within 50 mm of the device to keep TCK edges clean.
Do not confuse the EP1K30QC208-2N (208-PQFP) with the EP1K30TI144-2N (144-TQFP) or EP1K30FC256-2N (256-FBGA); the pin counts and ball maps differ, so PCB redesign is required. The ACEX 1K family is obsolete - verify long-term availability with distributors and consider migrating to the Cyclone IV/V series for new designs to avoid future last-time-buy situations.
合規資訊
ACEX 1K is a legacy Altera/Intel FPGA family designed before modern RoHS-era compliance labeling was standard. RoHS, REACH, lead-free and halogen-free status should be confirmed with the distributor at order time based on the specific date code and lot. AEC-Q100 is not applicable - this is a commercial-grade FPGA.
