EPF10K50STC144-3 개요
A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be configured by the customer or designer after manufacturing to implement arbitrary digital logic. The FLEX 10KS architecture is a hierarchical SRAM-based PLD that combines fine-grain logic elements (LEs) grouped into Logic Array Blocks (LABs) with embedded array blocks (EABs) for memory functions. Within the broader taxonomy, the FLEX 10KS sits below modern Cyclone and Stratix families but above simple CPLDs, targeting glue-logic, bus-bridging, and medium-density state-machine designs.
Key features include 360 LABs, 102 maximum user I/Os, JTAG IEEE Std. 1149.1 boundary-scan support built-in, and on-chip configuration memory. The 144-LQFP (also referenced as LFQFP / TQFP) package is a plastic gull-wing surface-mount form factor rated for commercial operating temperature. The SRAM-based configuration is volatile, requiring an external configuration device (EPC) at power-up. A built-in Joint Test Action Group (JTAG) boundary-scan test circuit is compliant with IEEE Std. 1149.1-1990 and consumes no additional device logic.
The EPF10K50STC144-3 -3 speed grade offers tighter propagation delay than the -2 grade of the same family, making it preferred for designs that approach the upper frequency ceiling of 166.67 MHz. The architecture is implemented in a 0.22 um CMOS process, and the device is intended for commercial (0C to 70C) operating environments.
Typical applications include telecommunications interface cards, industrial control and bridging logic, mid-density bus controllers, and legacy system upgrades. Design considerations for this device include mandatory configuration ROM selection (EPC1/EPC2 family), careful power-supply sequencing of 2.5V core and 5.0V I/O rails, and I/O bank planning against the available 102 user pins. Note: the FLEX 10K family is mature and was succeeded by ACEX 1K, Cyclone, and MAX families in the Altera (now Intel PSG) roadmap.

일반적인 애플리케이션
EPF10K50STC144-3 적합 용도: 6 애플리케이션s: Telecommunications Interface Card, Industrial Control and Bridging Logic, Mid-Density Bus Controller, Legacy System Upgrade and Repair, Test and Measurement Equipment, Aerospace Ground Equipment and Avionics Test.
Telecommunications Interface Card
The EPF10K50STC144-3's 50,000-gate density and 2,880 logic elements are well-suited to telecom interface cards implementing channelized protocols, framing logic, and physical-layer adaptation. Its 102 user I/Os accommodate parallel data buses and serial control interfaces; the 166.67 MHz internal frequency supports high-speed glue logic. Compared with discrete 74-series logic, the FLEX 10KS reduces board area while keeping timing deterministic. The 144-LQFP package enables standard SMT assembly on existing telecom backplanes without BGA rework. For legacy T1/E1, SONET framing, and HDLC controllers, this device remains a validated choice in carrier-grade equipment.
추천
Industrial Control and Bridging Logic
Industrial PLC and motion-controller backplanes use the EPF10K50STC144-3 to bridge legacy fieldbuses (Profibus, Modbus, CAN) to modern Ethernet or PCI backplanes. The 40,960 bits of on-chip RAM allow buffer storage for packet reassembly and rate matching between asynchronous domains. With 102 user I/Os, the device can interface directly to opto-isolated 24V industrial I/O banks and provide deterministic glue logic for scan-cycle timing. The commercial 0C-70C operating range covers most factory-floor environments; for harsher industrial sites the industrial-grade EPF10K30ETI144-3 alternative should be considered.
추천
Mid-Density Bus Controller
The EPF10K50STC144-3 fits mid-density bus-controller roles such as VME, ISA-to-PCI bridges, and custom backplane arbiters. Its 50K-gate capacity accommodates state-machine-based arbitration, address decoding, and interrupt handling for several bus masters. The 166.67 MHz internal frequency and 0.6 ns propagation delay (typical) allow zero-wait-state operation with 33 MHz PCI peripherals. The 144-LQFP package's generous lead pitch simplifies rework and inspection on legacy backplane designs. Designers transitioning to PCI Express should migrate to Cyclone IV GX or later families.
추천
Legacy System Upgrade and Repair
The EPF10K50STC144-3 is widely used as a repair/maintenance part for legacy equipment originally designed around the FLEX 10KS family. Field engineers stock this part for board-level replacement in production lines, military electronics, and aerospace ground equipment where PCB redesign is impractical. Because the die is mature and pinout-stable, original Altera-generated bitstreams can be reloaded from a configuration EPROM without firmware changes. XAIPART and authorized distributors maintain stock specifically for long-life-cycle repair scenarios; expect broker pricing for low-volume orders.
추천
Test and Measurement Equipment
ATE and bench-instrument designers used the EPF10K50STC144-3 as a flexible pattern-generator and protocol-decoder engine because the 50K-gate density fits complex stimulus sequences and timing generators in a single chip. The 2,880 logic elements and 40,960 RAM bits enable deep capture buffers, while 102 user I/Os drive front-panel connectors and ATE pin electronics. The 5V-tolerant I/O simplified interface to legacy TTL/CMOS instrumentation without level shifters. For modern PXI-based testers, migrate to Cyclone V or MAX 10 with on-chip ADCs and better Quartus tool support.
추천
Aerospace Ground Equipment and Avionics Test
The EPF10K50STC144-3 historically populated avionics test benches, radar-signal simulators, and ground-control interfaces where 5V-tolerant I/O and commercial-grade temperature screening were acceptable. Its deterministic 0.6 ns propagation delay (typical) allows tight ARINC 429 and MIL-STD-1553 protocol timing without clock-multiplication tricks. Long-life-cycle aerospace programs continue to procure this part via authorized brokers; aerospace-qualified screening (e.g., EPF10K50STI144-3 industrial grade) is recommended when available. Plan forward migration to radiation-tolerant Microsemi/Actel or modern Xilinx UltraScale for new flight hardware.

주요 차별점
- Highest speed grade (-3) of the FLEX 10KS family (vs EPF10K50STC144-2)
- FLEX 10KS architecture with 5V I/O tolerance (vs EPF10K50ETC144-3 (FLEX 10KE))
- Forward-migration path to ACEX 1K in same footprint (vs EP1K50TC144-3N (ACEX 1K))
설계 노트
The EPF10K50STC144-3 requires a tightly regulated 2.5V core supply (VCCINT) and a separate I/O supply (VCCIO) that can be 3.3V or 5.0V. Power-up sequencing must bring VCCINT up before or simultaneously with VCCIO to avoid I/O latch-up. Decouple every VCCINT pin with 0.1 uF ceramic plus 10 uF bulk tantalum placed within 5 mm of the package leads. The configuration device (EPC1/EPC2) should be powered from the same VCCIO rail to ensure clean configuration at power-up.
Do not assume FLEX 10KS pinout is drop-in compatible with FLEX 10KE (EPF10K50ETC144-3) without checking the datasheet. Although both share the 144-LQFP package, certain dedicated pins (MSEL, CLK, JTAG) may differ between the KS and KE variants. Also note that this device is SRAM-volatile; without a configuration EPROM the FPGA loads garbage logic and may drive I/O randomly at power-up, which can damage downstream components if protection diodes are not present.
Route all 102 user I/O traces with controlled impedance (50 ohm single-ended for LVTTL) and match length groups if used as source-synchronous buses. Place the EPC configuration EPROM within 25 mm of the FPGA to avoid configuration-clock skew issues. Provide a global ground plane directly under the 144-LQFP thermal pad; although the LQFP has no exposed pad like QFN, ground stitching vias should surround the package to suppress VCCIO switching noise.
