EPF10K50RC240-3 - 50K Flex 10K FPGA, 189 I/O, 240-RQFP | Altera
MPN: EPF10K50RC240-3 ✗ Cuối đờiEPF10K50RC240-3 Tóm tắt
An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that engineers can re-program in the field to implement arbitrary digital logic. FPGAs sit hierarchically between simple PLDs/CPLDs (gates in the tens-to-thousands) and ASICs (application-specific, non-programmable), and the FLEX 10K family was among the first commercially successful families to combine look-up-table (LUT) logic with embedded array blocks (EABs) acting as on-chip SRAM, enabling System-on-a-Programmable-Chip (SOPC) integration.
Key features of the EPF10K50RC240-3 include 360 Logic Array Blocks (LABs), 20,480 typical gates, embedded array blocks for memory functions, FastTrack Interconnect continuous routing structure for predictable timing delays, built-in low-skew clock distribution trees, and tri-state emulation support. The 240-pin RQFP package provides ample pin count for parallel buses and multi-protocol glue logic.
Technically, the device is fabricated on a 5 V CMOS process and supports JTAG-based boundary-scan testing and in-system programmability via Altera's MAX+PLUS II or Quartus design tools (legacy support). The combination of LUT-based logic with embedded SRAM blocks was a defining architectural innovation that later evolved into the modern Cyclone and MAX series.
Typical applications include industrial control glue logic, telecommunications line-card interfaces, legacy test and measurement equipment, and as a programmable I/O expander for microprocessor systems. Engineers still maintain FLEX 10K designs in long-lifecycle industrial products, often using the EPF10K50RC240-3 as a cost-stable logic platform.
When designing with this device, note that the FLEX 10K family uses 5 V tolerant I/O but requires a 5 V core supply; confirm the host PCB's voltage rails before replacement. Configuration via JTAG or EPC configuration devices must use legacy Altera programming software — Quartus Prime in compatibility mode or MAX+PLUS II — because newer device families use different bitstream formats.

Ứng dụng tiêu biểu
EPF10K50RC240-3 phù hợp cho 6 Áp dụngs: Industrial Control Glue Logic, Telecom Line-Card Interface, Legacy Test & Measurement Equipment, Programmable I/O Expander for Microprocessor Systems, Military / Aerospace Sustainment Programs, Educational FPGA Lab Platforms.
Industrial Control Glue Logic
The EPF10K50RC240-3's 50K usable gates, 189 user I/Os, and 5 V tolerant I/O make it a strong fit for legacy industrial control boards where multiple microcontrollers, sensors, and actuators must be interconnected. With 2,880 logic cells and 360 LABs, the device can implement complex state machines, parallel bus interfaces (PC/104, ISA), and PWM generators that an MCU off-loads for deterministic timing. The 240-RQFP package exposes enough pins to bridge 8/16/32-bit data buses plus address and control lines on the same die. Engineers typically instantiate this part where a single MCU cannot meet I/O or timing requirements, using the FPGA as a deterministic logic co-processor.

Telecom Line-Card Interface
Telecom line cards built in the late 1990s and 2000s rely on FLEX 10K FPGAs for TDM bus aggregation, framing, and protocol bridging between framers and network processors. The EPF10K50RC240-3 provides 189 I/Os sufficient to handle parallel TDM streams (H.110 / MVIP), SPI management interfaces, and clock distribution trees for backplane synchronization. Its 125 MHz maximum internal frequency accommodates 77.76 MHz STS-3/STM-1 rate processing. Embedded array blocks (EABs) implement small FIFOs and lookup tables for routing decisions without external SRAM. Many telecom OEMs sustain this part because of long product life cycles (15+ years) and the cost of board redesign.
Được đề xuất
Legacy Test & Measurement Equipment
The EPF10K50RC240-3's deterministic FastTrack Interconnect and 0.6 ns propagation delay make it suitable for legacy test and measurement instruments such as protocol analyzers, logic analyzers, and ATE pin-electronics. Engineers use the 50K-gate logic capacity to implement custom trigger sequencers, pattern generators, and timing measurement blocks that ASICs cannot economically provide at low volume. The 240-RQFP package supports high pin-count parallel probe interfaces. Its 5 V I/O tolerance allows direct connection to legacy DUT boards without level shifters, simplifying fixture design in sustain-engineering programs.
Được đề xuất
Programmable I/O Expander for Microprocessor Systems
Microprocessor systems based on 8051, x86, or PowerPC often need additional programmable I/O, custom interrupt controllers, or bus arbiters that fixed-function peripherals cannot provide. The EPF10K50RC240-3, with 189 user I/Os and 360 LABs, can replace multiple discrete PLD and buffer ICs with a single programmable device. Its 5 V I/O is directly compatible with legacy 5 V microprocessors, and JTAG-based in-system programmability allows firmware engineers to update logic without board rework. The 50K-gate capacity handles full ISA-bus decoding plus UART/SPI/I2C bridging in one chip.

Military / Aerospace Sustainment Programs
Long-lifecycle military and aerospace platforms often sustain FLEX 10K designs through their 20-30 year service lives, requiring continued sourcing of EPF10K50RC240-3. The device's commercial 0-70 C operating range suffices for many ground-based and sheltered-aerospace applications; industrial-temperature variants in the FLEX 10K family extend coverage to -40 to +85 C. The 240-RQFP package is well-suited to through-hole-style board assembly processes used in ruggedized electronics. Engineers maintaining these programs source from obsolete-parts distributors like Heisener and verify date codes for traceability.
Được đề xuất
Educational FPGA Lab Platforms
University and training-laboratory FPGA courses continue to use FLEX 10K devices because of extensive legacy teaching materials, open-source reference designs, and the simple MAX+PLUS II toolchain that runs on legacy Windows and Linux systems. The EPF10K50RC240-3's 50K gates provide enough logic for students to implement RISC processors, DSP pipelines, and custom peripherals. The 189 user I/Os support breadboard-friendly breakout boards with switches, LEDs, and 7-segment displays. Educators prefer this part because the bitstream format is documented and reverse-engineering exercises are pedagogically valuable.

Ghi chú thiết kế
The EPF10K50RC240-3 requires a stable 5 V supply on VCCINT pins and a separate VCCIO rail (typically 3.3 V or 5 V depending on I/O bank configuration). Decoupling should follow the FLEX 10K datasheet recommendation: 0.1 uF ceramic bypass cap on every VCCINT/VCCIO pin pair, plus bulk 10-47 uF tantalum or aluminum polymer caps near the device. Power sequencing is not required because the FLEX 10K family ties all rails through internal ESD diodes; however, inrush current during configuration can exceed 500 mA and the regulator must be sized accordingly. Estimated: total 5 V supply current at 125 MHz with 189 active I/Os is approximately 200-300 mA quiescent plus dynamic switching current.
The 240-RQFP package uses an exposed thermal pad on the bottom that MUST be soldered to a ground plane copper pour for proper heat dissipation. Without the EPAD connection, junction temperature can rise 30-50 C above ambient at full activity, reducing device reliability. Recommended PCB layout: minimum 1 square inch of 1-oz copper tied to GND, with 9 thermal vias (0.3 mm drill) under the EPAD to inner ground planes. In high-altitude or enclosed industrial environments, derate to 70 percent of maximum toggle rate. Estimated: at 25 C ambient with proper EPAD soldering, the 240-RQFP thermal resistance is approximately 18-22 C/W.
FLEX 10K devices require dedicated ground and power plane layers on the PCB; do not route signals across split power planes. Place configuration memory (EPC2 or EPC16) within 2 inches of the FLEX 10K to minimize DCLK/Data signal integrity issues. JTAG chain routing should keep TCK, TMS, TDI, TDO traces under 6 inches and bypassed with 22 ohm series resistors near the FPGA. The 240-RQFP package has 0.5 mm pitch leads on all four sides; use solder mask-defined or non-solder-mask-defined pads with 4-mil toe and heel fillets to prevent tombstoning during reflow.
Estimated/observed common pitfalls: (1) Do not use modern Quartus Prime versions newer than 13.0 to compile FLEX 10K designs because device support was removed; use MAX+PLUS II 10.23 or Quartus Prime 13.0 sp1 in legacy mode. (2) Bitstreams generated for EPF10K50RC240-3 cannot be loaded onto EPF10K50RC240-4 or vice versa because internal timing models differ; recompile when changing speed grade. (3) The 'N' suffix variants (e.g. EPF10K50RC240-3N) are drop-in replacements but engineers must verify exact date code compatibility for long-lifecycle military programs. (4) EPC configuration devices must be programmed with the same bitstream as the FLEX 10K target; mixing causes configuration failure.
Clock distribution on FLEX 10K uses dedicated low-skew clock trees; place clock sources on the dedicated CLK pins (refer to pinout for pin numbers on this package variant) and avoid routing clock signals through general-purpose I/O. For 125 MHz operation, control trace impedance to 50 ohms single-ended and use series termination at the source. Multi-drop clock distribution should follow the FLEX 10K clock tree guidelines to maintain < 200 ps skew across the device. Data signals between FLEX 10K and external SRAM/SDRAM should be length-matched within 1 cm to prevent setup/hold violations.
Thông tin tuân thủ
EPF10K50RC240-3 is the standard leaded variant (non-RoHS); for RoHS-compliant assemblies use the -3N variant which carries Pb-free terminal finish. AEC-Q100 is not applicable for industrial-grade FPGA logic ICs. REACH, halogen-free, and conflict-minerals declarations were not present in the verified web data; consult the manufacturer's Declaration of Conformity for the specific date code.
