EPF10K50RI240-4N - 50K-Gate FLEX 10K FPGA, 189 I/O, 240-RQFP | Intel
MPN: EPF10K50RI240-4N ✗ Cuối đờiEPF10K50RI240-4N Tóm tắt
What is an FPGA? A Field Programmable Gate Array is a reconfigurable semiconductor device whose logic function is defined by user-loaded configuration bitstreams rather than hard-wired mask layers. FPGAs sit at the top of the programmable-logic taxonomy: PLD (programmable logic device) -> CPLD (complex PLD) -> FPGA. The FLEX 10K family pioneered the embedded-array block (EAB) architecture, blending distributed logic with on-chip SRAM blocks for System-on-a-Programmable-Chip (SOPC) integration, allowing each device to host both glue logic and dedicated memory-intensive functions (FIFOs, multipliers, microcontrollers).
Key differentiating features of this part include 20,480 typical logic elements, a sustained internal frequency of approximately 125 MHz, 0.6 ns propagation delay, 3.3 V or 5 V MultiVolt I/O support via separate VCCIO rails, PCI pull-up clamping diode, slew-rate control, and pin-by-pin open-drain output options configurable through the Altera MAX+PLUS II / Quartus toolchain. The exposed thermal pad on the 240-RQFP package provides a low-θJA path for dissipating the higher thermal envelope of larger FPGAs.
Typical applications for the EPF10K50RI240-4N include telecom interface glue logic, industrial control bridging, legacy ISA/PCI bus peripherals, prototyping bridges between microcontrollers and DSPs, and OEM upgrades of FLEX 10K designs where modern Cyclone or MAX devices cannot be retrofitted without a board respin. Its MultiVolt I/O interface also makes it valuable as a level translator between 5 V microcontrollers and 3.3 V peripherals.
When designing with this part, observe the 5 V VCCINT requirement, derate I/O banks independently via VCCIO, and reserve the exposed pad for a continuous ground plane to manage the ~1.5 W typical quiescent power. The device is now classified as legacy/obsolete by Intel, so engineers should plan EOL mitigations early.

Ứng dụng tiêu biểu
EPF10K50RI240-4N phù hợp cho 6 Áp dụngs: Legacy Telecom Interface Glue Logic, Industrial Control Bridging, Legacy ISA/PCI Peripheral Cards, DSP-to-Microcontroller Bridge / Co-processor, 5 V to 3.3 V Level Translation / Glue Logic Hub, Long-Life-Cycle Aerospace / Defense Sustainment.
Legacy Telecom Interface Glue Logic
The EPF10K50RI240-4N is well suited for legacy telecom interface glue logic where 5 V PCI-style signaling and MultiVolt I/O are still in service. Its 50K-gate capacity and 189 user I/Os are sufficient for bridging between TDM backplanes, T1/E1 framers, and HDLC controllers, while 20,480 logic elements accommodate wide bus-multiplexing and protocol state machines. Engineers can dedicate ~10 Embedded Array Blocks (EABs) of 2 Kbit SRAM each to dual-port FIFOs that smooth traffic between the telecom line and an upstream processor. The 240-RQFP footprint matches the original Altera reference designs, allowing direct retrofit into FLEX 10K service cards without PCB rework. Programming is performed with MAX+PLUS II, which is still the toolchain of record for installed telecom fleets worldwide.

Industrial Control Bridging
The EPF10K50RI240-4N's industrial -40 °C to 85 °C temperature range and 5 V PCI-compatible MultiVolt I/O make it a reliable bridge in industrial PLC backplanes. Its 189 user I/Os map directly to opto-isolated 24 V field I/O modules through level shifters, while the 5 V VCCINT rail is immune to the noisy 24 V supply transients that plague lower-voltage FPGAs. With 360 LABs and 20,480 logic elements, the device comfortably hosts parallel motor-control state machines, encoder quadrature decoders, and PROFIBUS/Modbus glue. The exposed thermal pad on the 240-RQFP package provides the heat dissipation needed for continuous industrial duty cycles. Designers retain a long-term software path in MAX+PLUS II without needing to re-train on Quartus.

Legacy ISA/PCI Peripheral Cards
The EPF10K50RI240-4N was a workhorse for PCI 2.1-compliant peripherals in the late 1990s and continues to populate legacy test, instrumentation, and data-acquisition cards. Its built-in PCI pull-up clamping diode and 5 V PCI-compliant I/O bank remove the need for external bus transceivers, while 189 user I/Os are sufficient for 32-bit PCI plus local bus expansion. The on-chip EABs serve as dual-port FIFOs that decouple PCI bursts from analog front-end data streams, and the 125 MHz internal frequency supports 33 MHz PCI timing with margin. Designers working on long-life-cycle medical, aerospace, and military programs can extend the supply of original boards using FLEX 10K drop-in variants.

DSP-to-Microcontroller Bridge / Co-processor
The EPF10K50RI240-4N is a natural choice for bridging a host microcontroller to a DSP co-processor in legacy embedded designs. The 50K-gate capacity accommodates FIFO-based data paths between an SHARC or TMS320 DSP and an 8051-class host, while the MultiVolt I/O allows direct connection to 3.3 V DSPs and 5 V microcontrollers without external level shifters. The 10 EABs (each 2 Kbit) supply the dual-port RAM that pipelines Q-format samples between algorithms, and the 189 user I/Os handle host parallel ports, DMA handshakes, and JTAG. The exposed pad on the 240-RQFP package provides the headroom needed when both DSP and host operate at full clock under sustained DSP load.

5 V to 3.3 V Level Translation / Glue Logic Hub
The EPF10K50RI240-4N's MultiVolt I/O interface is its standout feature for mixed-voltage board designs. By tying VCCIO to either 3.3 V or 5 V on a per-bank basis, each I/O bank can talk directly to the corresponding voltage domain without external level shifters, eliminating dozens of discrete parts. The 189 user I/Os and 50K-gate logic capacity make this part ideal as a central 'glue hub' that consolidates bus arbitration, chip-select generation, and interrupt routing between a 5 V microcontroller and 3.3 V peripherals such as SDRAM, flash, and ADCs. The exposed thermal pad supports the continuous switching activity of bus multiplexing without thermal derating.

Long-Life-Cycle Aerospace / Defense Sustainment
The EPF10K50RI240-4N remains in service in aerospace and defense systems certified under long-life programs that pre-date Cyclone and MAX families. Its 5 V VCCINT and 240-RQFP package match the original Altera reference designs that are now maintained as form-fit-function replacements. The 189 user I/Os are sufficient for MIL-STD-1553 databus interfaces, ARINC 429 transmitters, and legacy display controllers. Industrial temperature range (-40 °C to 85 °C) covers most avionics bays, and the exposed thermal pad provides the heat-spreading path needed for sealed chassis without forced-air cooling. For certified programs, FLEX 10K variants from the same lot are a drop-in substitution, easing obsolescence management while the certification paperwork remains valid.

Ghi chú thiết kế
Estimated: the EPF10K50RI240-4N draws approximately 250-400 mA quiescent current on VCCINT at 5 V (1.25-2 W), scaling with toggle rate. Route VCCINT and VCCIO through wide power planes with bulk 100 uF + 10 uF + 0.1 uF ceramic decoupling at each pin. Separate VCCIO per bank: each MultiVolt bank can run at 3.3 V or 5 V independently, so use ferrite beads to isolate noisy banks from quiet ones. The exposed thermal pad MUST be soldered to a continuous ground plane for the datasheet's thermal resistance rating.
Use the Altera-supplied 240-RQFP land pattern from the Package Outlines section of the FLEX 10K datasheet. Place configuration EPROM (e.g., EPC2 or EPC16) within 100 mm of the FPGA to meet DCLK/DATA0 rise-time budgets. The MSEL0/MSEL1 pins select PS (passive serial), PPS, or JTAG configuration mode; add 10 kohm pull-ups to nCONFIG and 10 kohm pull-down to nSTATUS as recommended by the datasheet.
Do NOT attempt to program the EPF10K50RI240-4N with Quartus Prime - Quartus does not support the FLEX 10K family. Continue using MAX+PLUS II 10.23 baseline, which is the final toolchain release for FLEX 10K. The 'I' in the part number indicates industrial temperature range; verify that your chassis stays within -40C to +85C or the part may exhibit timing violations or reduced life. SRAM-based FPGAs lose configuration on power-down - always provide an external configuration PROM for production designs.
Thông tin tuân thủ
Compliance data not present in the verified web snippets. The -4N suffix historically indicates lead-free / Pb-free NiPdAu lead finish on the 240-RQFP package, but a written compliance certificate must be requested from the distributor for the specific lot. AEC-Q100 is not applicable because FPGAs are not automotive-qualified by Altera / Intel.
