EPF10K200SRC240-1 - 200K Gate FLEX-10KS FPGA, 240-RQFP | Intel
MPN: EPF10K200SRC240-1 ✗ Akhir HidupEPF10K200SRC240-1 Ringkasan
A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs), programmable interconnect, and programmable I/O cells. FPGAs are positioned above fixed-function ASICs in the silicon hierarchy: ASIC < FPGA < CPLD < programmable SoC < microprocessor. The FLEX 10K family pioneered embedded array blocks (EABs), which are RAM/ROM blocks that can be configured as wide SRAM, FIFO, ROM, or specialized logic, allowing each device to host both gates and megabytes of memory on one die. This makes FLEX 10K devices a bridge between simple glue-logic CPLDs and full-scale microprocessors.
Key features of the EPF10K200SRC240-1 include the FLEX 10K SRAM-based architecture with in-system programmability via IEEE 1149.1 JTAG, multiVolt I/O supporting 5.0 V, 3.3 V, and 2.5 V interfaces, four dedicated clock input pins with on-chip PLL-style clock management, and built-in boundary-scan test. The device integrates 24 EABs totaling 40,960 bits, supports true dual-port RAM configurations, and provides configurable high-drive I/O for backplane driving. Embedded JTAG circuitry adds up to 31,250 gates beyond the listed gate count for boundary-scan and test logic.
The 240-RQFP (32 x 32 mm BFQFP with exposed thermal pad) package exposes a metal pad on the underside for low thermal resistance and board-level grounding. Designers must use the standard FineLine BGA-pin-compatible migration strategy when planning a board that may move between FLEX 10K densities; Altera's datasheet recommends reserving only the I/O pins common to all candidate devices. Programming is performed through the JTAG port using Quartus II or MAX+PLUS II software.
Typical applications include telecom line-card glue logic, industrial control state machines, PCI bridge interfaces, and legacy 5 V prototyping platforms. The exposed-pad package requires a thermal via array and copper pour directly under the part for heat spreading.
When designing with this device, ensure all I/O banks share a common VCCIO if 5 V tolerance is required, since multiVolt I/O is per-bank. Designers migrating from FLEX 10K to FLEX 10KE should review the migration guide because EAB block RAM speeds and LAB interconnect changed between families.

Aplikasi Umum
EPF10K200SRC240-1 cocok untuk 7 aplikasis: Telecom Line-Card Glue Logic, Industrial Control and Factory Automation, Legacy PCI Bridge / Bus Interface, Embedded Memory / FIFO Buffer Systems, 5 V Prototype and Educational Platforms, Aerospace and Defense Legacy Systems, Test & Measurement Instrumentation Front-End.
Telecom Line-Card Glue Logic
The EPF10K200SRC240-1 is well suited to telecom line-card glue logic where 200K gates, 24 EABs (40,960 RAM bits), and 182 user I/Os are needed to bridge a network processor to framer/mapper ASICs. Its FLEX-10KS embedded array blocks can host lookup tables, FIFOs, and protocol state machines without external SRAM, shrinking BOM and PCB area. MultiVolt I/O supports 5.0 V framer interfaces alongside 3.3 V network-processor buses, removing level-shifters. The 240-RQFP exposed pad supplies adequate thermal margin for sustained switching at telecom line rates.

Industrial Control and Factory Automation
In industrial control PLC and motion-controller designs, the EPF10K200SRC240-1 provides the logic density to host multiple motor-control loops, encoder counters, and fieldbus glue logic in one device. Its -40C to +85C industrial temperature rating, 5.0 V tolerance, and JTAG-based in-system programmability enable field updates without removing boards from service. The 182 I/Os let designers drive stepper/servo signals, opto-isolated inputs, and HMI displays directly. Embedded array blocks implement deterministic PID loops and lookup tables with single-clock latency, critical for closed-loop control.
Direkomendasikan
Legacy PCI Bridge / Bus Interface
The EPF10K200SRC240-1 is frequently deployed as a PCI bridge or backplane interface controller in legacy 5.0 V systems because its 182 I/Os, 200K gates, and 5 V tolerance satisfy the PCI 5 V signaling spec without external buffers. Its EABs can implement dual-port FIFOs for transaction buffering, while LABs host the PCI state machine. MultiVolt I/O supports mixed 5 V/3.3 V buses in transition systems. Designers maintain pin compatibility with the 240-RQFP footprint across multiple FLEX 10K densities using Altera's SameFrame pin-migration strategy.
Direkomendasikan
Embedded Memory / FIFO Buffer Systems
Embedded memory and FIFO buffer subsystems benefit from the EPF10K200SRC240-1's 24 EABs delivering 40,960 bits of dual-port RAM plus 98,304 general SRAM bits - enough to implement multi-channel video line buffers, ADC FIFOs, and protocol reassembly queues on-chip. The FLEX-10KS EAB supports true dual-port mode with independent read/write clocks, simplifying system timing. Designers save PCB area and BOM cost versus external FIFOs. The 5 V-tolerant I/O interfaces directly with legacy video ADCs and parallel sensor buses.
Direkomendasikan
5 V Prototype and Educational Platforms
Universities, training labs, and 5 V prototype platforms continue to use the EPF10K200SRC240-1 because its 5.0 V core tolerance avoids the level-shifting required by newer 2.5 V/1.8 V FPGAs, simplifying breadboard and through-hole prototyping. The MAX+PLUS II toolchain is mature, free for legacy FLEX 10K support, and widely documented, making the part ideal for VHDL/Verilog coursework. Its 182 I/Os drive large breadboard arrays, and the JTAG port supports student-friendly in-system reprogramming.
Direkomendasikan
Aerospace and Defense Legacy Systems
Long-lifecycle aerospace and defense platforms continue to specify the EPF10K200SRC240-1 because of its mature process, proven reliability data, and ITAR-friendly supply chain. The 5.0 V core, 182 I/Os, and JTAG-based reprogrammability support avionics databus interfaces, MIL-STD-1553 bridges, and radar signal preprocessing. EABs implement high-reliability lookup tables and waveform tables. Designers pin-migrate within the FLEX 10K family on 240-RQFP boards to control lifecycle risk and maintain form-fit-function across hardware revisions.
Direkomendasikan
Test & Measurement Instrumentation Front-End
The EPF10K200SRC240-1 suits test & measurement front-ends where 5 V analog signal conditioning, 182 I/Os for parallel ADC/DAC routing, and on-chip FIFO buffering are essential. Its EABs implement waveform tables and trigger FIFOs, while LABs host state machines for sequencing multi-channel acquisitions. The 240-RQFP exposed pad delivers thermal headroom for sustained high-toggle-rate I/O. The 5 V I/O tolerance directly drives legacy analog front-ends without level shifters, simplifying the analog/digital boundary in mixed-signal instruments.

- 24 EABs (40,960 RAM bits) - largest embedded memory in the FLEX-10KS 240-RQFP family (vsEPF10K100ARC240-1 (FLEX 10K, 100K gates, 240-RQFP))
Catatan Desain
The 240-RQFP package exposes a metal thermal pad on its underside that MUST be soldered to a PCB copper pour with a thermal via array (typically 5x5 or 7x7 vias at 1.2 mm pitch, 0.3 mm drill). Without the exposed pad soldered, junction temperature can rise 30-40 C above safe limits under sustained high-toggle-rate I/O switching. Estimated: at 50% I/O toggling and 5.0 V VCC, internal dissipation can reach 1.5 W; theta-JA with exposed pad soldered is ~10 C/W versus ~25 C/W unsoldered. Reference the FLEX 10K Packaging Application Note for layout dimensions.
multiVolt I/O banks each require their own VCCIO rail. The 240-RQFP package exposes multiple VCCIO pins (e.g., pins 15, 36, 64, 91, 118, 145, 170, 198, 225) that may operate at 3.3 V or 5.0 V independently. Decouple each VCCIO pin with a 0.1 uF X7R ceramic placed within 5 mm of the pin, and add a bulk 10 uF tantalum per bank. All VCCINT pins (5.0 V core) must share a single regulated rail, not separate supplies, to prevent internal logic contention during power-up.
Do not confuse the FLEX 10K (this part, 5.0 V core) with the FLEX 10KE family (2.5 V core). Although the FLEX 10KE devices in 240-RQFP (EPF10K100EQC240-*, EPF10K130EQC240-*) share the same 240-pin footprint, the pinouts are NOT compatible because the EAB count, LAB count, and I/O mapping differ between families. Applying 5.0 V to a FLEX 10KE core will permanently damage the device. Verify the family suffix ("S" for FLEX 10KS, "E" for FLEX 10KE) before board bring-up.
The 182 user I/Os drive 5 V TTL/CMOS at moderate edge rates. Place 33 ohm series-termination resistors within 25 mm of the FPGA output when driving backplane traces longer than 50 mm, to suppress ringing. Use 4-layer PCB with continuous ground plane beneath the device; split planes under multiVolt I/O banks cause return-path discontinuities. For clock nets (CLK0-CLK3, DCLK), keep trace length matched within 5 mm and surround with ground stitching vias to control impedance.
Programming via JTAG requires TDI, TDO, TMS, TCK to be accessible on a 4-pin header or 10-pin Altera JTAG connector. If the board uses multiVolt I/O at 3.3 V, confirm the JTAG pins are 5.0 V tolerant at the FPGA side (FLEX 10KS JTAG is 5 V tolerant). Add a 1 kohm pull-up on nCONFIG and a 1 kohm pull-up on nSTATUS per the FLEX 10K Configuration Handbook; CONF_DONE typically needs a 5 kohm pull-up to VCCIO. Programming failures are most often caused by missing pull-ups or incorrect VCCIO bank voltage.
Informasi Konformitas
EPF10K200SRC240-1 is the legacy SnPb (lead-bearing) finish variant - NOT RoHS compliant per Altera/Intel datasheet ordering nomenclature. For RoHS-compliant build, choose EPF10K200SRC240-1X (X suffix = lead-free). REACH, halogen-free, and conflict-mineral status are not stated in the verified data; set to unknown. AEC-Q100 is not applicable because the part is not automotive-qualified.
