EPF10K30RI208-4N Обзор

The Intel (Altera) EPF10K30RI208-4N is a 30,000-gate FLEX 10K family field-programmable gate array (FPGA) with 1,728 logic cells, 12,288 RAM bits, and 147 user I/Os, packaged in a 208-pin Power Quad Flat Pack (RQFP/BFQFP) with exposed pad. It operates from a 5V supply on a 0.42 µm CMOS SRAM process, delivers system performance up to 125 MHz, and is rated for the industrial temperature range.

What is an FPGA? A field-programmable gate array (FPGA) is a semiconductor IC containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that the designer can reconfigure after manufacture to implement arbitrary digital logic. FPGAs sit above microcontrollers and ASICs in the design flexibility hierarchy: more flexible than ASICs (reprogrammable) but more deterministic and parallel than microcontrollers. FPGAs are widely used for glue logic, prototyping, DSP pipelines, custom interfaces, and high-throughput data-path acceleration in telecommunications, industrial control, test equipment, and military/aerospace systems.

Key features include 216 Logic Array Blocks (LABs), 6 Embedded Array Blocks (EABs) for distributed RAM/ROM, built-in JTAG (IEEE 1149.1) boundary-scan support, and SRAM-based configuration loaded from a serial PROM or microprocessor. The device supports MultiVolt I/O for interfacing to 3.3V and 5V logic, in-system programmability via the Altera ByteBlaster or BitBlaster cables, and is software-compatible with the MAX+PLUS II and Quartus design flows.

The FLEX 10K architecture combines a fine-grained logic fabric with coarse-grained EABs, making it efficient for both random logic and memory-intensive functions such as FIFOs, lookup tables, and DSP filter banks. Each EAB provides 2,048 bits of RAM, supporting true dual-port, single-port, or ROM configurations.

Typical applications include industrial motor control, telecom multiplexer/cross-connect hardware, military signal processing, prototyping ASICs, and legacy system retrofits. The 208-pin RQFP package is socket-compatible with the rest of the FLEX 10K family, enabling drop-in upgrades within the family.

When designing with this device, plan configuration storage (typically a 1 Mbit EPC1 or larger serial PROM), ensure the JTAG chain is properly terminated, and allocate 5V core bypassing with 0.1 µF + 10 µF capacitors near each supply pin.

It covers device architecture, pinout tables for all package options, AC/DC characteristics, and configuration timing. For pinout-specific data, the 'FLEX 10K Device Pin-Out' supplement for the 208-pin RQFP package should also be consulted.

What is the configuration memory requirement for EPF10K30RI208-4N?

The EPF10K30RI208-4N is SRAM-based and loses its configuration on power-down. A serial configuration PROM such as the Altera EPC1 (1 Mbit) or EPC2 (1.6 Mbit) is typically used, or a microcontroller can emulate the configuration master via the PS (Passive Serial) or PSA (Passive Parallel Asynchronous) modes. Bitstream size for the FLEX 10K family is approximately 60-120 Kbytes compressed.

What is the price of EPF10K30RI208-4N as of 2026-09-11?

As of 2026-09-11, the EPF10K30RI208-4N lists at approximately $56.00 USD at qty-1, with volume pricing dropping to $44.80 USD at 100 pieces and $36.40 USD at 500 pieces. The part is marked Not Recommended for New Designs (NRND) by Intel/Altera, and pricing reflects declining distributor inventory rather than active production.

Is the EPF10K30RI208-4N still in production?

No. Intel/Altera has classified the EPF10K30RI208-4N as Not Recommended for New Designs (NRND). The FLEX 10K family was superseded by the ACEX, APEX, Cyclone, and MAX families. Existing inventory is available through distributors (DigiKey lists 2,717 pieces as of the data snapshot), but long-term availability is not guaranteed.

EPF10K30RI208-4N vs EPF10K50RI208-4N - which is better for higher-density designs?

The EPF10K50RI208-4N offers roughly 50,000 equivalent gates versus 30,000 for the EPF10K30RI208-4N, with 2,880 logic cells, 360 LABs, and the same 208-pin RQFP footprint. For designs that exceed the 30K-gate capacity but must stay within the same PCB land pattern, the EPF10K50RI208-4N is the pin-compatible density upgrade. For new designs, however, a modern Cyclone or MAX device is strongly recommended.

Can the EPF10K30RI208-4N be replaced with a Cyclone series FPGA?

No, the EPF10K30RI208-4N cannot be replaced by a Cyclone series device as a drop-in. Cyclone devices use different packages, JTAG pin assignments, configuration schemes (AS/PS/Fast Passive Parallel), and bitstream formats. A PCB redesign and full re-verification are required. For functional replacement in a 208-pin RQFP-compatible package, the closest legacy option is another FLEX 10K variant such as the EPF10K50RI208-4N.

What software is required to program the EPF10K30RI208-4N?

Design entry and synthesis are supported by Altera MAX+PLUS II (legacy, recommended for FLEX 10K) and Quartus Prime (with FLEX 10K device support). Programming is performed using the Altera ByteBlaster II or USB-Blaster download cable via the JTAG port or the configuration PROM. Bitstream generation produces a .pof or .sof file targeting the selected configuration mode.

What is the maximum operating frequency of the EPF10K30RI208-4N?

The EPF10K30RI208-4N is the speed grade -4 of the FLEX 10K family, with a maximum system frequency of approximately 125 MHz per the family datasheet. Real-world performance depends heavily on routing, logic depth, and I/O register usage; designs with multiple cascaded LABs typically achieve lower fMAX. Use the Quartus TimeQuest timing analyzer to verify timing closure for your specific design.

What is the best drop-in replacement for EPF10K30RI208-4N?

The best drop-in replacement within the FLEX 10K family is the EPF10K30RC240-4N (240-pin RQFP variant with 189 user I/Os, same -4 speed grade and industrial temperature), although the larger package requires a PCB change. For 208-pin RQFP compatibility, the EPF10K30RI208-4 (lead-containing finish) and EPF10K50RI208-4N (higher density, same footprint) are the closest options. All preserve the FLEX 10K bitstream format.

What is the EPF10K30RI208-4N equivalent from Xilinx or Lattice?

No Xilinx or Lattice device is a true pin-compatible drop-in for the EPF10K30RI208-4N; the FLEX 10K uses Altera-proprietary configuration, JTAG commands, and bitstream format that no competitor replicates. The closest parametric competitors historically were the Xilinx XC4000XL and Spartan-II series, but these require new PCB layouts, new design software (ISE/Vivado), and full design re-verification. Migration to a competitor is treated as a redesign project, not a substitution.

What are the key specifications of EPF10K30RI208-4N that engineers should know?

The EPF10K30RI208-4N is a 30,000-gate / 1,728-logic-cell SRAM-based FPGA in a 208-pin Power QFP package. It operates at 5V core, supports MultiVolt 3.3V/5V I/O, and contains 6 Embedded Array Blocks providing 12,288 RAM bits (2,048 bits each) for distributed dual-port or single-port memory. The device runs up to 125 MHz in the -4 speed grade across the industrial -40°C to +85°C range, supports IEEE 1149.1 JTAG, and is configured via Altera EPC1/EPC2 serial PROMs in Passive Serial mode.

Руководство по выбору

Choose the EPF10K30RI208-4N when your design fits within 1,728 logic cells / 30K gates, requires 147 or fewer user I/Os, and must drop into an existing 208-pin Power QFP footprint in a RoHS-compliant product. It is the right answer for industrial control boards, telecom multiplexer cards, and legacy ASIC prototyping where the FLEX 10K design flow (MAX+PLUS II or Quartus with FLEX 10K support) is already established. Choose EPF10K30RI208-4 instead only if you are building lead-containing exempt products (military, aerospace, legacy replacements). For designs needing 50K gates, switch to EPF10K50RI208-4N without PCB changes. For more than 147 I/Os, the 240-pin EPF10K30RC240-4N is the same silicon with more I/O pins. For any new design, however, prefer the modern Cyclone IV or Cyclone V families, which offer lower power, lower cost, and active long-term support.

Заметки по проектированию

The EPF10K30RI208-4N requires a clean 5V core supply (VCCINT) and one or more 3.3V/5V I/O supplies (VCCIO) per bank. Place a 0.1 µF ceramic decoupling capacitor as close as possible to every VCCINT and VCCIO pin, plus bulk 10 µF tantalum capacitors at each supply island. During configuration the FPGA draws higher inrush current; ensure the upstream regulator can sustain at least 500 mA peak. FLEX 10K devices are not 5V-tolerant on JTAG TCK in some speed grades - verify input thresholds against the configuration PROM datasheet.

The 208-pin Power QFP (RQFP) has a 0.5 mm pin pitch and an exposed thermal pad that must be soldered to a copper pour for mechanical and thermal reliability. Use at least 4-layer PCB construction with dedicated power and ground planes; route all 147 user I/Os on the top layer and stitch the perimeter with a ground guard ring. Keep configuration (DCLK/DATA/CONF_DONE/nSTATUS) and JTAG traces under 50 mm total length to avoid signal-integrity issues, and place a 4.7 kΩ pull-up on nCONFIG and a 10 kΩ pull-up on nSTATUS per Altera AN-116.

Do not assume the FLEX 10K configuration bitstream is compatible with newer Cyclone or MAX devices - it is not. Always generate the bitstream with MAX+PLUS II or a Quartus version that lists FLEX 10K in the device family selector. Avoid leaving unused I/O pins floating; configure them as outputs driving ground through the software to prevent input oscillation that can draw spurious ICC. For industrial-temperature designs, verify that all configuration PROMs (EPC1/EPC2) are also rated for -40°C to +85°C operation, since a commercial-grade PROM can corrupt configuration at temperature extremes.
