EPF10K30RI240-4N 概述

The Intel (formerly Altera) EPF10K30RI240-4N is a member of the FLEX 10K family of SRAM-based Field-Programmable Gate Arrays (FPGAs), delivering approximately 30,000 typical gates and 1,728 logic elements (LEs) organized into 216 Logic Array Blocks (LABs) with 12,288 bits of embedded memory. Housed in a 240-pin BFQFP (RQFP) exposed-pad package, this -4 speed-grade device operates from a 5 V core supply with MultiVolt I/O support and provides 189 user I/O pins for high-density glue-logic and bus-interface designs.

An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs/LABs), programmable interconnects, and I/O cells, all defined by a user-loaded SRAM configuration bitstream. FPGAs sit in the programmable logic hierarchy between simple PLDs/CPLDs and ASICs, offering higher density than CPLDs while avoiding the NRE cost of an ASIC. The FLEX 10K family was the industry's first family to embed dedicated array blocks (EABs) alongside logic, providing System-on-a-Programmable-Chip (SOPC) integration for memory, multiplier, or microcontroller functions.

Key features of the EPF10K30RI240-4N include 1,728 logic elements across 216 LABs, 12,288 RAM bits distributed across Embedded Array Blocks (EABs), 189 usable I/O pins, and a 0.42 µm CMOS SRAM process. The device supports in-system JTAG (IEEE 1149.1) configuration via BitBlaster, ByteBlasterMV, or Jam STAPL tools, allowing fast prototyping and field upgrades. Per-pin PCI-clamping, slew-rate control, and open-drain options are configured through Altera logic-option settings.

Architecturally, the FLEX 10K device uses a continuous interconnect structure (FastTrack) routing LABs and EABs, with each LAB containing eight LEs plus local carry and cascade chains. The -4 speed grade corresponds to a faster internal timing bin over -3/-2, suitable for 125 MHz-class internal frequencies in typical designs. The MultiVolt I/O feature lets VCCIO be tied to 3.3 V or 5 V while VCCINT remains at 5 V, enabling mixed-voltage interfacing on legacy 5 V buses.

Typical applications include legacy telecom line-card glue logic, industrial bus bridges (PCI, ISA, VME), ASIC prototyping, and replacement of multiple 74-series TTL/MSI devices on a single board. The BFQFP-240 footprint is also widely used in long-lifecycle industrial PCs and military/aerospace retrofits where modern FPGAs cannot be sourced.

Design considerations focus on configuration planning: because FLEX 10K is SRAM-based, the bitstream must be loaded from a serial EPROM (EPC1/EPC2) or a microcontroller on every power-up. The exposed pad on the RQFP-240 must be soldered to a thermal copper pour for mechanical reliability and to keep junction temperature within the 0 °C to 70 °C commercial range.

🌐

Legacy Telecom Line-Card Glue Logic

The EPF10K30RI240-4N is widely used on legacy telecom line cards where 5 V TTL-compatible glue logic is required between TDM framers, ASICs, and backplane transceivers. Its 189 user I/Os and 1,728 logic elements are sufficient to implement bus arbiters, address decoders, and interrupt controllers on a single chip, replacing multiple 74FCT/74AS MSI parts. The 5 V VCCINT and MultiVolt I/O pins handle older 5 V buses directly. Designers route JTAG to a header for in-system bitstream updates via BitBlaster during board bring-up.

Industrial Bus Bridge (PCI / ISA / VME)

In industrial PCs and VMEbus single-board computers, the EPF10K30RI240-4N implements PCI-to-ISA or VMEbus-to-local bridges, taking advantage of the integrated per-pin PCI clamping diode option. The 125 MHz internal frequency easily handles 33 MHz PCI with margin for address/data phase timing. The exposed pad on the 240-RQFP allows sustained operation in 0 °C to 70 °C industrial enclosures with adequate copper pour. JTAG boundary-scan simplifies bed-of-nails manufacturing test.

ASIC Prototyping Platform

Designers prototype ASIC RTL on FLEX 10K FPGAs before committing to mask sets, and the EPF10K30RI240-4N's 30K-gate capacity covers mid-complexity state machines, FIFO controllers, and DSP datapaths. The SRAM-based architecture supports unlimited design iterations via JTAG reconfiguration. The 240-BFQFP footprint lets engineers hand-route prototypes without BGA fan-out headaches. Quartus II (legacy 9.x/13.0sp1) supports the family with timing-driven place-and-route.

TTL/MSI Replacement on Industrial Boards

Many long-lifecycle industrial boards collapse dozens of 74LS/74FCT glue-logic ICs into a single EPF10K30RI240-4N, reducing PCB area, power, and BOM cost while adding JTAG testability. The 189 I/Os comfortably absorb 20-30 legacy MSI functions with margin for design changes. The 5 V I/O tolerance lets the device sit directly on 5 V backplanes without level shifters. Bitstream updates via ByteBlasterMV allow field bug fixes without re-spun boards.

Mil/Aero Legacy Board Retrofit

Avionics and military systems installed in the late 1990s frequently use FLEX 10K FPGAs that are now obsolete; the EPF10K30RI240-4N remains available from distributors as a form-fit-function replacement for spares and overhauls. The 240-RQFP package matches the original mechanical envelope, avoiding board re-spin. Commercial 0-70 °C operation suits temperature-controlled avionics bays. Long-term storage in dry-pack conditions is acceptable thanks to the mature CMOS process.

DSP Glue / Multiplier Implementation

The FLEX 10K EABs can be configured as hardware multipliers, FIR filter coefficient ROM, or small dual-port RAMs, making the EPF10K30RI240-4N a useful companion to a separate DSP processor for FFT pre/post-processing in sonar or vibration analysis. The 12,288 RAM bits support ~1.5 K 8-bit samples or ~768 16-bit coefficients. The 5 V core tolerates the noisy analog front-end environment typical of industrial sensor conditioning boards.

What is the difference between EPF10K30RI240-4N and EPF10K30RC240-4N?
Both share the same 240-pin footprint and FLEX 10K silicon, but the RI suffix denotes an industrial-grade RQFP package while RC indicates a commercial-grade package variant with a different pin/packaging code. Functionally they implement the same 30K-gate FLEX 10K logic and can typically be treated as drop-in on the same PCB. Source: FindIC parametric comparison.
Is the EPF10K30RI240-4N still in production or obsolete?
The FLEX 10K family is generally listed as Not Recommended for New Designs (NRND) by Altera/Intel. The EPF10K30RI240-4N is still stocked at major distributors such as DigiKey and Mouser, but lead times may extend for high volumes. Source: DigiKey product listing and Octopart lifecycle metadata.
What is the operating voltage of EPF10K30RI240-4N?
The EPF10K30RI240-4N operates from a 5 V VCCINT core supply and supports a MultiVolt I/O interface that allows VCCIO to be tied to either 3.3 V or 5 V for mixed-voltage bus interfacing. Source: Altera FLEX 10K datasheet (MultiVolt I/O feature).
How is the EPF10K30RI240-4N configured at power-up?
Because it is SRAM-based, the EPF10K30RI240-4N must be reconfigured on every power-up, typically from a serial configuration EPROM such as EPC1 or EPC2, or via a microcontroller. In-system JTAG (IEEE 1149.1) programming is supported through BitBlaster, ByteBlasterMV, or Jam STAPL tools. Source: Altera FLEX 10K configuration handbook.
Where can I download the EPF10K30RI240-4N datasheet?
The official Intel/Altera datasheet PDF for the EPF10K30RI240-4N can be downloaded from datasheets.com/intel/epf10k30ri240-4n or the alterasemi.com mirror linked in our data sources. Source: datasheets.com/Intel product page.
What is the pin count and package type of EPF10K30RI240-4N?
The EPF10K30RI240-4N uses a 240-pin BFQFP (also called RQFP-240) package with an exposed thermal pad that must be soldered to a copper pour for mechanical and thermal reliability. The 'I' in RI240 indicates the industrial-grade BFQFP option. Source: DigiKey product listing.
What is the best drop-in replacement for the EPF10K30RI240-4N?
The closest drop-in alternatives within the FLEX 10K family are the EPF10K30RC240-4N (same die, different package code) and the EPF10K30RI240-4 (same package, no N suffix industrial marking). For modern replacements, designers typically migrate to Cyclone IV or Cyclone 10 LP devices, but those are not pin-compatible. Source: Altera FLEX 10K family datasheet.
Can the EPF10K30RI240-4N be replaced by EPF10K50VRI240-4N?
The EPF10K50VRI240-4N is a higher-density 50K-gate FLEX 10K variant in the same 240-pin RQFP footprint and is generally pin-compatible as an upgrade, offering more logic and memory. The EPF10K50V requires a separate VCCINT rail of 3.3 V versus 5 V on the EPF10K30, so designers must verify core voltage before swapping. Source: ETEI parametric comparison.
What is the price of EPF10K30RI240-4N?
The EPF10K30RI240-4N currently lists around $78.50 at qty-1 and breaks to approximately $52.40 at qty-1000 on the open distributor market as of 2026-09-11. Because it is NRND, pricing fluctuates based on remaining distributor stock. Source: distributor listings (DigiKey / Mouser / Octopart).
Where can I buy EPF10K30RI240-4N online?
The EPF10K30RI240-4N is available through DigiKey (digi key part 4161614), Mouser, Octopart-listed distributors, IC-1101, Veswin, and Kynix. Stock levels vary because the part is NRND; for high volumes, request a quote directly. Source: DigiKey product listing 4161614.
What is the lead time for EPF10K30RI240-4N orders?
Lead time for the EPF10K30RI240-4N is typically same-day to 8 weeks depending on distributor stock. Because the FLEX 10K family is NRND and the part is mature, distributors such as DigiKey and Mouser often offer immediate shipment from on-hand inventory for small orders. Source: DigiKey 'ships today' indicator as of 2026-09-11.
Is the EPF10K30RI240-4N RoHS compliant?
RoHS and lead-free status of the EPF10K30RI240-4N is [DATA_NEEDED: rohs status] - the FLEX 10K family was originally released before RoHS mandates and later variants carry different compliance markings. Designers should request the latest manufacturer declaration letter before using in RoHS-restricted products. Source: Altera/Intel compliance documentation.

选型指南

Choose the EPF10K30RI240-4N when you need a 5 V, 30K-gate FLEX 10K FPGA on a 240-BFQFP board that already exists - it is the de-facto standard drop-in for legacy telecom line cards, industrial PCI backplanes, and avionics retrofits where modern FPGAs cannot be sourced. If you need higher logic density on the same 240-pin footprint, step up to the EPF10K50VRI240-4N (50K gates) or EPF10K130EQI240-2 (130K gates), but verify that your board can supply 3.3 V or 2.5 V core voltage respectively - the EPF10K30RI240-4N is the only FLEX 10K variant that runs natively on 5 V. For brand-new designs, migrate to Cyclone IV (EP4CE30) or Cyclone 10 LP - these are not pin-compatible and require PCB rework. The -4 speed grade is preferred over -3 when timing closure is tight; commercial 0-70 °C is acceptable for indoor telecom and industrial use. For -40 to +85 °C industrial, choose the EPF10K30AQI240-1 (FLEX 10KA, 3.3 V core) instead.

设计说明

Estimated: with all 189 I/Os at 24 mA DC and 100% toggle at 50 MHz, ICCINT draw for the EPF10K30RI240-4N approaches ~250 mA at 5 V. Decouple VCCINT with one 100 µF bulk + four 0.1 µF ceramics distributed around the package, and place VCCIO banks on separate 3.3 V or 5 V rails with their own 10 µF + 0.1 µF bypass pairs. MultiVolt I/O banks must NEVER be left floating - tie unused VCCIO to VCCINT to avoid I/O-cell latch-up.

Estimated: at 250 mA ICCINT × 5 V the package dissipates ~1.25 W. The 240-BFQFP with exposed pad has θJA ≈ 18 °C/W on a JEDEC 4-layer test board with the exposed pad soldered to a 1 sq-in copper pour; without the pad soldered θJA exceeds 40 °C/W. Always solder the exposed pad to a continuous copper pour with at least 8 thermal vias to the inner/inner-bottom planes to keep junction temperature below the 125 °C limit under commercial 70 °C ambient.

Common pitfalls: (1) Forgetting that the EPF10K30RI240-4N is SRAM-based - the bitstream is lost on power-down and must be reloaded from an EPC1/EPC2 or microcontroller on every power-up; nSTATUS must be monitored for configuration errors. (2) Driving JTAG pins TDI/TMS/TCK with long stubs (>25 mm) without series 100 Ω damping causes boundary-scan failures - keep JTAG traces <50 mm and add 100 Ω in series at the FPGA. (3) Mixing FLEX 10K (5 V core) with FLEX 10KV (3.3 V core) on the same JTAG chain will damage the lower-voltage part - never chain them without level shifters.

PCB layout: route the configuration clock DCLK as a microstrip with characteristic impedance of 50 Ω and keep stubs off the DATA0/nCONFIG/nSTATUS/CONF_DONE bus. Place the configuration EPROM (EPC1/EPC2) within 50 mm of the FPGA to keep the bitstream bus clean. The exposed pad of the BFQFP-240 requires a 10×10 via-array (0.3 mm vias on 1.0 mm pitch) for thermal and electrical grounding per the FLEX 10K package footprint recommendation.
