EP1K50TI144-2X Présentation

The Intel EP1K50TI144-2X is a 50,000-gate Field Programmable Gate Array from the ACEX 1K family, housed in a 144-pin TQFP (Industrial temperature grade) package. The device integrates 2,880 logic elements organized as 360 Configurable Logic Blocks (LABs/CLBs), 40,960 bits of embedded SRAM, and 102 maximum user I/O pins. The '2X' speed grade designation places it in Altera's mid-range performance tier for this family.

ACEX 1K is Altera's low-cost, SRAM-based FPGA family that bridges the gap between CPLDs and high-density FPGAs. As a field programmable gate array, an ACEX 1K device stores its configuration in volatile SRAM cells that must be loaded from an external PROM or controller at every power-up. The architecture combines look-up table (LUT)-based logic with embedded memory blocks, providing designers with a balance of logic density and on-chip storage for glue logic, bus interfacing, and small state-machine implementations.

Key features of the EP1K50TI144-2X include a maximum operating frequency up to 833 MHz on internal paths, true LVTTL/LVCMOS/PCI-compliant I/O with user-configurable slew rate and drive strength, on-chip impedance matching, and built-in JTAG (IEEE 1149.1) boundary-scan support for board-level testing. The embedded array blocks (EABs) provide dedicated RAM/ROM functionality with widths up to 16 bits.

The EP1K50TI144-2X uses a 0.18 µm CMOS process and operates from a 2.5 V core supply (VCCINT) with separate VCCIO banks that support mixed-voltage I/O standards (3.3 V, 2.5 V, 1.8 V). Industrial temperature grade parts (suffix 'I') are guaranteed across -40 °C to +100 °C operation, making the part suitable for non-automotive industrial, telecom, and instrumentation applications. Designers configure the device using Altera's MAX+PLUS II or Quartus development software, both of which support schematic, VHDL, and Verilog entry with synthesis, fitting, and timing analysis.

Typical applications include industrial control interfaces, glue logic for legacy system upgrades, custom peripheral controllers in telecom equipment, low-density data-path acceleration, and prototyping vehicles for newer Cyclone/MAX 10 designs. The 144-pin TQFP with 0.5 mm pitch remains a familiar through-hole-friendly footprint for engineers migrating away from larger BGA-only devices.

When designing with this part, ensure the configuration source (EPC2, EPC4, or microcontroller) matches the FPGA's 2.5 V VCCINT requirement and that JTAG chain integrity is preserved. Designers planning long-term production should note that ACEX 1K is a mature legacy family; current production designs should target Cyclone IV, MAX 10, or MAX V devices instead.

Applications typiques

EP1K50TI144-2X convient pour 6 applications: Industrial Glue Logic & Bus Interface Bridging, Legacy Telecom Peripheral Controller, Test & Measurement Instrumentation Front-End, Prototyping Vehicle for Cyclone / MAX 10 Migration, Custom State-Machine & Sequencer in Industrial Drives, Aerospace & Defense Avionics Databus Interface.

🏭

Industrial Glue Logic & Bus Interface Bridging

The EP1K50TI144-2X is well suited as a 50K-gate industrial glue-logic bridge, replacing multiple 74-series TTL packages, PALs, and small CPLDs with a single programmable device. Its 2,880 logic elements and 102 user I/Os comfortably handle parallel bus multiplexing, address decoding, and protocol translation between legacy ISA, parallel ATA, or VME buses and modern microcontrollers. The industrial -40 °C to +100 °C temperature grade is essential for factory-floor and outdoor cabinet deployments. Designers use the on-chip 40,960 bits of SRAM for FIFO buffers and command queues, eliminating external SRAM in many bus-interface implementations. Quartus II synthesis with VHDL or Verilog produces JEDEC-compatible SOF/POF files that load at power-up from an EPC2/EPC4 configuration PROM.

🌐

Legacy Telecom Peripheral Controller

In telecom shelves where the backplane uses parallel TDM buses (H.110, MVIP), the EP1K50TI144-2X serves as a custom peripheral controller aggregating multiple E1/T1 framers or HDLC controllers onto a host processor's local bus. The TQFP-144 package's 102 available user I/Os easily route 8-bit host data plus 16-bit address plus interrupt and DMA handshake signals. SRAM-based configuration allows field firmware upgrades via JTAG without removing the board from service. The -2 speed grade comfortably exceeds 33 MHz PCI and 50 MHz host-local-bus timing requirements with margin. Industrial temperature tolerance supports central-office and outdoor-cabinet environments.

🖥️

Test & Measurement Instrumentation Front-End

The EP1K50TI144-2X is used in mid-range oscilloscopes, logic analyzers, and protocol analyzers as the timing/control front-end between analog acquisition paths and the host DSP/MCU. Its 360 LABs can implement custom trigger state machines, pattern generators, and timing measurement blocks. The 40,960 bits of embedded SRAM provide capture buffers for short pre-trigger sequences without external memory. LVCMOS 3.3 V I/O interfaces cleanly with modern ADC front-ends while the 2.5 V core keeps dissipation modest in sealed benchtop enclosures. The device's JTAG (IEEE 1149.1) support simplifies board-level boundary-scan test during manufacturing.

🔧

Prototyping Vehicle for Cyclone / MAX 10 Migration

Engineers use the EP1K50TI144-2X as a hardware-equivalent prototyping vehicle when migrating mature ACEX 1K designs to Cyclone IV, MAX V, or MAX 10 devices. The TQFP-144 footprint allows engineers to breadboard a drop-in replacement card that runs the legacy .POF file, validating the existing firmware before porting HDL to the new family. Quartus II 9.1sp2 supports both the source ACEX 1K and target Cyclone/MAX device libraries, enabling side-by-side simulation. This 'reference design' pattern shrinks migration risk by isolating HDL changes from board changes.

⚡

Custom State-Machine & Sequencer in Industrial Drives

Variable-frequency drives, servo amplifiers, and UPS systems use the EP1K50TI144-2X as a deterministic state-machine and PWM sequencer between the DSP controller and the power-stage gate drivers. The 360 LABs implement protection interlocks, soft-start ramps, and fault-recovery sequencers that must respond within microseconds. Industrial temperature grade survives the high-ambient environment inside a sealed drive enclosure. The 50K-gate density fits exactly between small CPLDs (which lack the I/O count) and large Cyclone devices (which are over-specified for this role), making the EP1K50TI144-2X a cost-effective sweet spot.

✈️

Aerospace & Defense Avionics Databus Interface

In lower-tier avionics and UAV ground-station databus cards, the EP1K50TI144-2X implements MIL-STD-1553, ARINC 429, and RS-422 protocol engines with on-chip buffering. The 102 user I/Os comfortably accommodate dual-redundant 1553 channels plus ARINC receive/transmit pairs. SRAM-based configuration allows field updates of protocol bit-rates and message-filter tables. Industrial temperature grade meets RTCA DO-160 environmental categories for non-pressurized equipment bays. Designers pair it with companion transceivers and use JTAG for production boundary-scan and field return diagnostics.

What family does the EP1K50TI144-2X belong to?
The EP1K50TI144-2X belongs to Intel's (formerly Altera) ACEX 1K family of SRAM-based FPGAs. ACEX 1K is a low-cost, mature programmable logic family that combines look-up table (LUT) logic with embedded array blocks (EABs) for on-chip memory, targeting glue-logic, bus-interface, and small state-machine designs where densities of roughly 10K-100K equivalent gates are sufficient.
How many logic elements and user I/O pins does EP1K50TI144-2X provide?
The EP1K50TI144-2X provides 2,880 logic elements organized as 360 LABs/CLBs, 40,960 bits of embedded SRAM, and up to 102 user I/O pins on its 144-pin TQFP package. Per the Altera ACEX 1K datasheet family, this gives roughly 50,000 typical gates of logic capacity, which is the upper density of the family.
What core and I/O voltages does EP1K50TI144-2X require?
The EP1K50TI144-2X requires a 2.5 V core supply (VCCINT) for the internal logic and SRAM configuration cells. The I/O banks (VCCIO) can be independently powered at 3.3 V, 2.5 V, or 1.8 V depending on the LVCMOS/LVTTL/PCI standard you need to interface. Mixed-voltage designs must respect the bank's VCCIO selection.
Is EP1K50TI144-2X still in production?
The ACEX 1K family is mature and listed in Altera/Intel's legacy product catalog with last-time-buy or NRND (Not Recommended for New Designs) status. The 'X' suffix historically indicates the part is supplied in tape-and-reel packaging; for current production designs, migrate to MAX V, MAX 10, or Cyclone IV/V equivalents per the Intel product-discontinuance notices.
Where can I download the EP1K50TI144-2X datasheet PDF?
The original ACEX 1K datasheet PDF is hosted by Altera/Intel at the legacy datasheet URL https://www.alterasemi.com/datasheet/alterasemi/EP1K50TI144-2.pdf and on the Altera Document Library archive. Distributor listings on DigiKey, Mouser, and Octopart also link directly to the datasheet from their product pages.
What is the pinout of EP1K50TI144-2X?
The 144-pin TQFP package uses a 0.5 mm pitch with gull-wing leads. Pin 1 is located at the top-left of the package marker (per JEDEC MS-026). The complete pin map including dedicated configuration pins (MSEL0, MSEL1, nCE, nCONFIG, CONF_DONE, nSTATUS, DCLK), JTAG pins (TCK, TMS, TDI, TDO), user I/O, and power/ground is provided in the pinout section of this page and matches the Altera ACEX 1K device handbook.
What is the best drop-in replacement for EP1K50TI144-2X?
The pin-compatible drop-in replacement within the same ACEX 1K family is EP1K50TI144-2 (industrial grade, speed grade 2, tray packaging). For a step-up in speed, use EP1K50TI144-2N (speed grade 2, lead-free). For a step-down in cost, use EP1K50TI144-1X (speed grade 1, tape-and-reel). All share the same TQFP-144 footprint and JTAG pinout.
What is the difference between EP1K50TI144-2X and EP1K50TI144-2?
EP1K50TI144-2X and EP1K50TI144-2 share the same ACEX-1K die, the same 144-pin TQFP package, the same industrial temperature grade, and the same -2 speed grade. The only difference is packaging format: the 'X' suffix denotes tape-and-reel (versus tray for the unmarked version). They are electrically and pin-for-pin identical.

EP1K50TI144-2X vs EP1K50TI144-2Q - which is better for industrial applications?
For industrial applications requiring the same -2 speed grade, both EP1K50TI144-2X (tape-and-reel) and EP1K50TI144-2Q (tray) perform identically. Choose EP1K50TI144-2Q for low-volume prototype or hand-assembly runs where tray packaging is convenient, and EP1K50TI144-2X for high-volume SMT production lines that consume tape-and-reel.
EP1K50TI144-2X vs MAX V 5M80ZE64 - which should I choose for a new design?
Choose MAX V 5M80ZE64 for any new design: it is in active production, has lower power, supports flash-based instant-on configuration (no external PROM), and is offered in a smaller EQFP-64 package. Choose EP1K50TI144-2X only when you must maintain an exact board-level footprint for legacy repair, second-source qualification, or when a stable, qualified production socket is unavailable.
Is the EP1K50TI144-2X the same as the EP1K50TI144-2N?
The EP1K50TI144-2X and EP1K50TI144-2N share the same TQFP-144 package, the same industrial temperature grade, and the same -2 speed grade. They differ only in lead-free finish (-2N is lead-free per RoHS) and packaging format (-2X is tape-and-reel, -2N is tray). They are pin-for-pin compatible.
When should I choose EP1K50TI144-2X over a Cyclone IV EP4CE6E22?
Choose EP1K50TI144-2X only when you need drop-in replacement on an existing ACEX 1K PCB footprint (the TQFP-144 is easier to hand-rework than a Cyclone IV EQFP) or when you have qualified firmware/POF files that must run on identical silicon. For new designs, choose EP4CE6E22 - it offers 6,272 logic elements, more memory, lower power, and active product lifecycle support.
What Altera/Intel software is needed to program EP1K50TI144-2X?
The EP1K50TI144-2X is supported by Altera MAX+PLUS II (legacy) and Altera/Intel Quartus II (versions 9.0 and earlier; newer Quartus versions have removed ACEX 1K support). To generate a programming file, use MAX+PLUS II 10.23 or Quartus II 9.1sp2 with the ACEX1K device library enabled. Output formats include .SOF (SRAM Object File) and .POF (Programmer Object File for the configuration device).

Guide de sélection

Choose EP1K50TI144-2X when you must sustain production of a board already designed around the ACEX 1K TQFP-144 footprint, especially when the board has been qualified for industrial -40 °C to +100 °C operation and you want tape-and-reel packaging for an SMT line. The 'X' suffix means tape-and-reel; if you need a tray for prototype build, select EP1K50TI144-2 (no suffix) or EP1K50TI144-2N (lead-free tray). If your design hits the timing margin at the -2 speed grade, stay with the -2 variants; if you have timing headroom and want lower cost, drop to EP1K50TI144-1X (speed grade -1). For all new designs, migrate to MAX V 5M80ZE64 or Cyclone IV EP4CE6E22 - both are in active production, have lower power, and re-target from the same VHDL/Verilog with Quartus. Keep EP1K50TI144-2X in your BOM only for legacy sustainment and exact-footprint replacement scenarios.

Principaux différenciateurs

  • Tape-and-reel format for high-volume SMT production (vs EP1K50TI144-2N (tray))
  • Same-die -2 speed grade (mid-tier) for balanced fMAX/cost (vs EP1K50TI144-1X (speed grade -1))
  • TQFP-144 footprint enables hand-rework and socketed qualification (vs EP4CE6E22 (Cyclone IV EQFP-144, smaller pitch))

Notes de conception

The EP1K50TI144-2X requires a clean 2.5 V ±5% rail (VCCINT) for the core logic and SRAM configuration cells; ripple above 100 mV pk-pk can corrupt configuration and cause bit-level errors that manifest as intermittent functional failures. Decouple every VCCINT pin (typically 6 pins on the TQFP-144) with a 0.1 µF X7R ceramic placed within 5 mm of the pin, and add a single 10 µF tantalum or polymer bulk capacitor near the FPGA's power pin cluster. Each VCCIO bank (4 banks) must be decoupled independently because mixing 3.3 V and 2.5 V standards on different banks is a common use case.

Route the configuration bus (DCLK, DATA0, nCONFIG, nSTATUS, CONF_DONE) as a short, guarded group to keep them isolated from switching I/O. Place the configuration PROM (EPC2 or EPC4) on the same side of the PCB as the FPGA to minimize stub lengths; long configuration traces cause intermittent configuration failures above 20 MHz DCLK. Provide a pull-up (10 kΩ) on nCONFIG and CONF_DONE per the ACEX 1K handbook; omitting these prevents the device from entering user mode.

The 144-pin TQFP at 0.5 mm pitch is hand-solderable but stack-up sensitive. Use a 4-layer PCB with a continuous ground plane directly under the FPGA to provide the reference for the high-pin-count package; without it, signal-integrity on the inner rows of I/O degrades noticeably above 50 MHz. JTAG (TCK/TMS/TDI/TDO) traces should be length-matched within 25 mm and kept clear of clock edges to meet IEEE 1149.1 timing.

Do not assume the 'X' suffix denotes a different speed grade - it is a packaging-format indicator (tape-and-reel), and confusing it with the -2 speed grade is a common source of order errors. Avoid using the EP1K50TI144-2X in new designs unless maintenance of an existing board layout is the primary requirement; the ACEX 1K family is in last-time-buy status. For new designs, migrate to MAX V 5M80ZE64 or Cyclone IV EP4CE6E22 and reuse the HDL via Quartus re-targeting.
