EPF10K30RI240-4N - 30K FLEX-10K FPGA, 189 I/O, 240-BFQFP | Intel
MPN: EPF10K30RI240-4N ✗ Cuối đờiEPF10K30RI240-4N Tóm tắt
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.

Ứng dụng tiêu biểu
EPF10K30RI240-4N phù hợp cho 6 Áp dụngs: Legacy Telecom Line-Card Glue Logic, Industrial Bus Bridge (PCI / ISA / VME), ASIC Prototyping Platform, TTL/MSI Replacement on Industrial Boards, Mil/Aero Legacy Board Retrofit, DSP Glue / Multiplier Implementation.
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.
Được đề xuất
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.
Được đề xuất
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.
Được đề xuất
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.
Được đề xuất
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.
Được đề xuất
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.

Ghi chú thiết kế
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.
