EP1K50TI144-4N Présentation
An FPGA (Field-Programmable Gate Array) is a programmable logic device that combines configurable logic blocks (LEs), programmable routing, and I/O cells into a single silicon die. Within the broader semiconductor hierarchy, an FPGA sits under the umbrella of programmable logic (PLD > CPLD > FPGA). The ACEX 1K family belongs to the low-cost, moderate-density segment of the Altera (now Intel) portfolio, designed to replace multiple discrete logic ICs with one re-programmable device that can be re-flashed in-system via JTAG.
Key features include 40,960 typical usable gates, a 12.6 Kbit embedded array block (EAB) for memory or multiplier functions, six dedicated input pins, hot-socketing support, and MultiVolt I/O allowing 2.5V/3.3V/5.0V interfacing. The -4 speed grade is one of the faster bin selections in the family, supporting system clock frequencies up to approximately 90 MHz depending on the design's logic depth. The device is configured at power-up from a serial configuration EPROM or via the JTAG port.
Architecturally, each logic element contains a 4-input look-up table (LUT), a programmable register, carry-chain logic, and cascade-chain logic for wide functions. The embedded array blocks (EABs) provide dual-port RAM, ROM, or synchronous arithmetic functions, making the EP1K50TI144-4N suitable for FIFO buffers, small DSP blocks, and protocol translators. Configuration bitstream is loaded from an EPC2 or EPC8 serial configuration device.
Typical applications include bus-interface bridging (e.g., PCI to local bus), industrial control glue logic, telecommunications backplane multiplexing, low-density data-path processing, and prototyping of larger Altera designs before silicon migration to Cyclone or MAX families. Designers moving production volumes today usually port to the equivalent logic on a Cyclone III/IV device, but the EP1K50TI144-4N remains a valuable drop-in for legacy boards and long-life industrial equipment.
When designing with this device, observe the 2.375V-2.625V core supply tolerance, place 0.1 µF decoupling capacitors within 5 mm of every supply pin, and tie unused I/O banks to a defined logic level through the Quartus software's default pin assignment. The configuration pins (nCONFIG, nSTATUS, CONF_DONE) must be pulled correctly during power-up sequencing to prevent partial configuration.

Applications typiques
EP1K50TI144-4N convient pour 6 applications: Bus Interface Bridging, Industrial Control Glue Logic, Telecommunications Backplane Multiplexing, Low-Density Data-Path Processing, Legacy Board Maintenance and Field Replacement, Rapid Prototyping of New Altera Designs.
Bus Interface Bridging
The EP1K50TI144-4N excels at bus-bridge applications where two incompatible bus protocols must meet, such as PCI-to-local-bus or ISA-to-memory interfaces. With 102 user I/O plus 6 dedicated inputs, the device can sink a 32-bit data bus plus full address and control signal sets on both ports simultaneously. The 2,880 logic elements easily implement state machines for bus arbitration, while the 12.6 Kbit EABs provide FIFO buffers for protocol translation. According to the Altera ACEX 1K datasheet, the -4 speed grade supports bus transfers up to ~33 MHz, sufficient for legacy PCI 33 MHz and most parallel bus interfaces found in industrial and embedded designs.
Recommandé
Industrial Control Glue Logic
Factory automation systems often need to consolidate multiple 74-series logic chips, small state machines, and timers into one re-programmable device. The EP1K50TI144-4N's industrial -40 °C to +85 °C temperature range and 2.5 V core / MultiVolt I/O make it a direct fit for 5 V PLC backplanes and 3.3 V motor-controller boards. Its 2,880 logic elements and 10 EABs replace dozens of discrete gates, reducing board area and assembly cost. According to the ACEX 1K datasheet, hot-socketing support allows insertion into live backplanes without latch-up. Pair the FPGA with a serial EEPROM configuration device and JTAG header for in-field firmware updates over years of operation.
Recommandé
Telecommunications Backplane Multiplexing
Legacy telecom equipment such as TDM backplanes, E1/T1 framers, and HDLC controllers often require custom multiplexing, framing, or protocol-conversion logic that does not fit a fixed-function ASIC. The EP1K50TI144-4N's combination of 102 user I/O, 12.6 Kbit embedded memory, and 90 MHz internal clock capacity suits TDM bus multiplexers up to ~8 Mbps. The MultiVolt I/O interfaces directly to 5 V TTL E1 transceivers and 3.3 V framers. According to Altera application notes, ACEX 1K designs typically implement 4-8 channel HDLC controllers plus elastic-store FIFOs in one EP1K50, replacing two or more dedicated ASICs. The TQFP-144 footprint also simplifies thermal management in dense shelf-mount equipment.
Recommandé
Low-Density Data-Path Processing
Imaging pipelines, sensor aggregators, and signal-conditioning front-ends often need moderate-density datapath logic without the cost of a large FPGA. The EP1K50TI144-4N's 10 EABs provide 12.6 Kbits of dual-port RAM, sufficient for line buffers, small lookup tables, and FIFO depths of 256-1024 entries. Designers can implement 8-bit FIR filters, pixel-format converters, and custom serializers at clock rates up to 90 MHz. Compared to a CPLD of similar logic density, the ACEX 1K architecture provides more registered logic and far more embedded memory. The 144-pin TQFP gives access to 102 I/O for wide datapaths, and the JTAG port enables on-board hardware-debug and logic-analyzer signal probing via SignalTap-equivalent workflows in the Quartus toolchain.
Recommandé
Legacy Board Maintenance and Field Replacement
A common application is direct maintenance of legacy boards still in service in industrial, aerospace, defense, and medical equipment where the original ACEX 1K design must be preserved exactly. The EP1K50TI144-4N's TQFP-144 footprint, identical pinout to the -3N/-2N/-1N variants, and stored Quartus bitstream compatibility make it a straightforward swap-in replacement. Designers rebuilding a stock of spare FPGAs for a long-life product can mix speed grades as long as the -4 timing budget is met by the slowest device used. According to Intel's product-discontinuance notice, ACEX 1K parts are supported through authorized legacy distributors and configuration tools remain available in the Quartus II 13.0 web edition.
Recommandé
Rapid Prototyping of New Altera Designs
Engineers often use the EP1K50TI144-4N as a low-cost prototyping platform to validate Quartus designs intended for larger Cyclone, Cyclone II, or Cyclone III devices. The same Quartus II toolchain targets ACEX 1K and Cyclone families, allowing a design to be compiled first for the EP1K50 to verify logic and timing, then re-targeted to the production Cyclone silicon. With 2,880 logic elements and 102 I/O, the EP1K50TI144-4N provides enough capacity to test medium-complexity state machines, custom peripherals, and bus interfaces before committing to a more expensive prototype. The 144-pin TQFP is breadboard-friendly and inexpensive JTAG programmers such as the Altera ByteBlasterMV or USB-Blaster clone support the device directly.

Notes de conception
The EP1K50TI144-4N requires a clean 2.5 V core supply with tolerance 2.375-2.625 V. Place a 100 µF bulk tantalum capacitor and four 0.1 µF ceramic decoupling capacitors within 5 mm of the four VCCINT pins (20, 58, 81, 114, 138). Each of the four I/O bank supplies (VCCIO1-VCCIO4, pins 7, 33, 45, 69, 92, 105, 127) requires its own 0.1 µF decoupling cap. Power-up sequencing must hold nCONFIG low until VCCINT and all VCCIO banks reach their nominal voltage, then release nCONFIG to begin configuration. Estimated: total quiescent current for a fully-utilized EP1K50 design is 50-150 mA on VCCINT depending on toggle rate.
Route all four dedicated configuration signals (nCONFIG, nSTATUS, CONF_DONE, DCLK) as short traces (< 25 mm) and keep them away from high-frequency switching nets. Add a 10 kΩ pull-up to VCCIO on nCONFIG and CONF_DONE. Connect the JTAG chain (TCK, TMS, TDI, TDO) in series with any other JTAG devices on the board, with 10 kΩ pull-ups on TCK, TMS, and TDI to VCCIO. Provide a 4-pin header or 0.1-inch JTAG footprint for the Altera ByteBlasterMV or USB-Blaster programmer. Route differential clocks on the inner PCB layers with continuous ground reference.
Three pitfalls are common when bringing up an EP1K50TI144-4N design: (1) leaving nCONFIG floating - it must be pulled high through 10 kΩ to VCCIO; (2) failing to terminate CONF_DONE with a pull-up, which prevents the FPGA from entering user mode and the rest of the board never sees a valid reset release; (3) driving I/O pins before configuration completes - CONF_DONE should be used to enable downstream logic. Additionally, when migrating designs to the EP1K50TI144-3N for cost reasons, re-run the Quartus timing analyzer at the slower speed grade to confirm timing closure; a design that fits -4 may violate setup/hold at -3.
Although the EP1K50TI144-4N is a moderate-speed device by today's standards, the 102 user I/O pins can generate simultaneous switching noise (SSN) that couples into the 2.5 V core supply. Place a ferrite bead or 10 Ω resistor in series with each VCCIO bank supply and add 10 µF tantalum + 0.1 µF ceramic bulk decoupling. Limit the number of simultaneously switching outputs per bank to ~20 to avoid ground bounce. For clock distribution, use the FPGA's dedicated clock inputs (CLK pins) rather than routing a clock through general-purpose I/O logic, which minimizes skew.
Informations de conformité
RoHS, REACH, lead-free, halogen-free, and conflict-mineral status for the EP1K50TI144-4N were not stated in the verified web data and are marked unknown. The part is obsolete (Intel/Altera PCN 2008-era ACEX 1K EOL notice) so historical compliance status from the datasheet era is the only available reference. AEC-Q100 is not applicable - ACEX 1K was not offered in automotive qualification.
