EP1K50TI144-3N جائزہ

The Altera (now Intel Programmable Solutions Group) EP1K50TI144-3N is a 50,000-gate member of the ACEX 1K family of CMOS field-programmable gate arrays, housed in a 144-pin TQFP (Industrial-grade, -3 speed grade, lead-free) package. The device integrates 2,880 logic elements, 40,960 bits of embedded array (EAB) SRAM, and provides 102 user I/O pins on a 2.5 V core supply (VCCINT 2.375 V to 2.625 V), with separate VCCIO banks supporting mixed-voltage I/O standards.

ACEX 1K is a fine-grain, SRAM-based FPGA family introduced by Altera in the late 1990s and built on a 0.22 µm CMOS process. It is positioned in the taxonomy: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit. The "EP1K" prefix denotes the family, "50" the gate-count tier (50K system gates), "TI" indicates the TQFP-144 industrial-temperature package, and the "-3N" suffix marks the -3 speed grade (fastest of the three ACEX 1K grades) with lead-free (Pb-free) NiPdAu terminal finish.

Key features include up to 49,760 typical gates, 2,880 logic elements (LEs), 40 embedded array blocks (EABs, each 4 Kbit, total 40,960 RAM bits), 102 maximum user I/O, in-system programmability via a 4-pin JTAG (IEEE 1149.1) interface plus a passive-serial configuration scheme, multiVolt I/O supporting 2.5 V / 3.3 V / 5.0 V interfacing, and industrial operating temperature range of -40 °C to +85 °C. The -3 speed grade delivers internal clock frequencies above 166 MHz and is suited to glue-logic, bus-interface, and DSP-front-end designs.

Typical applications include industrial control and factory-automation glue logic, communications infrastructure line-card glue logic, legacy PCI/ISA bus bridges, telecom backplane controllers, and cost-sensitive DSP pre-/post-processing pipelines where 50K gates are sufficient. The TQFP-144 industrial package is widely used in long-lifecycle designs where surface-mount rework and standard PCB-assembly processes are required.

When designing, observe that ACEX 1K is volatile and must be configured from a serial PROM or a microprocessor on every power-up. The device uses a 2.5 V core supply and requires a configuration clock and DONE/Open-drain configuration-status signals to the host. A 100 µF bulk plus 0.1 µF decoupling network per VCC/VCCIO pin is recommended, plus a JTAG chain that supports ISP and board-level testing. Note that the ACEX 1K family has been in NRND/EOL transition since the mid-2010s - verify long-term supply before new design-in.

This page synthesizes distributor inventory, drop-in ACEX 1K speed-grade alternatives, and practical configuration-layout guidance not consolidated in the original Altera datasheet.

What is the logic capacity of the EP1K50TI144-3N?

The EP1K50TI144-3N provides 50,000 typical system gates and 2,880 logic elements (LEs), backed by 40 embedded array blocks (EABs) totaling 40,960 bits of SRAM. According to Altera ACEX 1K datasheets, this density tier targets glue-logic, bus-interface, and moderate DSP pre-processing designs. The "50" suffix denotes the 50K-gate tier within the EP1K family (which also includes EP1K10, EP1K30, and EP1K100).

How many user I/O pins does the EP1K50TI144-3N expose?

The EP1K50TI144-3N exposes 102 user I/O pins plus 6 dedicated inputs in its 144-pin TQFP package. This is the maximum I/O count for the EP1K50 die in the TQFP-144 package; the larger PQFP-208 and BGA-256/484 packages offer the same die with more I/O. According to the Altera datasheet, two of the 144 pins are VCC/GND, two are JTAG, and the remainder are configuration or I/O.

What is the difference between EP1K50TI144-3N and EP1K50TI144-2N?

The only difference between the EP1K50TI144-3N and EP1K50TI144-2N is the speed grade: the -3 grade is the fastest ACEX 1K tier (~166 MHz internal), the -2 is mid-speed (~133 MHz), and the -1 is the slowest (~100 MHz). The die, package (TQFP-144), logic capacity (50K gates / 2,880 LEs), pinout, and configuration interface are identical, so the parts are drop-in compatible provided timing closure is re-verified at the chosen grade.

What core and I/O voltages does the EP1K50TI144-3N require?

The EP1K50TI144-3N requires a 2.5 V nominal core supply (VCCINT) within the 2.375 V to 2.625 V range, and supports multiVolt I/O with VCCIO at 2.5 V, 3.3 V, or 5.0 V to interface with surrounding logic. Per the Altera datasheet, separate VCCINT and VCCIO power planes are required, each with bulk plus 0.1 µF high-frequency decoupling placed close to the package pins.

Is the EP1K50TI144-3N still in production or end-of-life?

The EP1K50TI144-3N is in NRND (Not Recommended for New Designs) status, with the ACEX 1K family having been in long-term availability under Intel PSG after the 2015 Altera acquisition. Authorised distributors (Chip1Stop, Mouser, Avnet, Arrow) typically still carry stock, and Intel continues to ship against last-time-buy orders for many ACEX 1K speed grades, but lead times have stretched to 12-26 weeks. New designs should evaluate Cyclone IV/V or MAX 10 as modern replacements.

Where can I buy the EP1K50TI144-3N and what is the current price?

The EP1K50TI144-3N is available from authorised Altera/Intel distributors including DigiKey, Mouser, Arrow, Avnet, and brokers such as Chip1Stop and Octopart-listed suppliers. As of 2026-09-07, single-unit pricing is approximately USD 38.50, with 100-piece pricing near USD 28.95 and 1,000-piece pricing around USD 19.80. Lead time on distributor shelves is typically 8-12 weeks; long-lead factory orders should be placed well in advance.

Where do I download the EP1K50TI144-3N datasheet?

The official ACEX 1K datasheet can be downloaded from the Intel Programmable Solutions Group website at https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/cy2/cyc2_05.pdf (ACEX 1K data sheet, 86 pages). Third-party distributors including Alldatasheet, FPGAkey, and Jotrin also host cached PDF copies. The datasheet covers pinout, timing, configuration, JTAG BSDL, and thermal characteristics for the entire EP1K family including the EP1K50TI144-3N.

What is the pinout configuration of the EP1K50TI144-3N?

The EP1K50TI144-3N uses a 144-pin TQFP package with pin 1 at the top-left (indicator dot), numbered counter-clockwise around the body. Key pins include dedicated clock (CLK0/CLK1 at pins 43/44 per the ACEX 1K handbook), JTAG (TCK/TMS/TDO/TDI on dedicated pins), configuration (nCONFIG/nSTATUS/CONF_DONE), VCCINT (2.5 V) on multiple pins, VCCIO banks split across the package, and 102 user I/O on the remaining general-purpose pins. The full pin map is in the ACEX 1K datasheet, chapter 6.

Is the EP1K50TI144-3N drop-in compatible with EP1K50TC144-3N?

Yes - the EP1K50TI144-3N and EP1K50TC144-3N are pin-compatible and functionally interchangeable in the TQFP-144 footprint. The "I" in TI denotes Industrial temperature grade (-40 °C to +85 °C) while "C" denotes Commercial (0 °C to +70 °C); the EP1K50TI144-3N can replace the TC variant in any design with no PCB changes. Conversely, the TC variant must not replace the TI part in a design that requires industrial temperature operation.

Can I use a Cyclone IV or MAX 10 as a modern replacement for EP1K50TI144-3N?

Yes - Intel recommends Cyclone IV E (EP4CE6/EP4CE10 in EQFP-144) or MAX 10 (10M02/10M04 in EQFP-144) as modern replacements for the EP1K50TI144-3N. These are NOT drop-in compatible (different pinout, different power rails: 1.2 V core), so the PCB requires a re-spin. However, the migration is supported by the Quartus "Project Migration" wizard which converts ACEX 1K pin assignments to Cyclone IV. Expect a 5-10× lower static power and free Quartus Prime Lite tool support.

What is the difference between ACEX 1K and FLEX 10K FPGA families?

ACEX 1K is the cost-reduced, 2.5 V-core successor to the 5 V / 3.3 V FLEX 10K family, sharing the same Look-Up Table (LUT)-based logic element and EAB architecture but on a 0.22 µm process instead of 0.5 µm. ACEX 1K offers up to 100K gates and 49,152 RAM bits versus FLEX 10K's 250K gates and 40,960 RAM bits in the largest die. According to Altera literature, ACEX 1K uses a 4-pin passive-serial configuration scheme compatible with EPC2/EPC4/EPC8 PROMs, simplifying in-system programming.

What configuration PROM does the EP1K50TI144-3N require?

The EP1K50TI144-3N configures from any Altera/Intel serial configuration PROM in the EPC2, EPC4, EPC8, or EPC16 family via the 4-pin passive-serial interface (DCLK/DATA/nCS/OE). For a 50K-gate design, the EPC8 (8 Mbit) or EPC16 (16 Mbit) is typically recommended. ByteBlasterMV or USB-Blaster download cables program the device directly via JTAG (IEEE 1149.1) for development, eliminating the need for a dedicated PROM during prototyping.

Does the EP1K50TI144-3N support in-system programming (ISP)?

Yes - the EP1K50TI144-3N supports in-system programming through the JTAG (IEEE 1149.1) interface, allowing field upgrades without removing the device from the board. According to the ACEX 1K handbook, the JTAG chain supports both boundary-scan test and full SRAM configuration bitstream reload. For production, the bitstream can also be stored in a serial PROM and reloaded into the FPGA via passive-serial at every power-up.

What is the best cross-brand replacement for EP1K50TI144-3N?

The EP1K50TI144-3N has no true pin-compatible, drop-in equivalent from Xilinx, Lattice, or Microsemi - all competing 50K-gate-class FPGAs of that era use different packages and pinouts. The closest functional equivalents requiring PCB re-spin are Xilinx XC95288XL (CPLD, 288 macrocells, TQFP-144) for low-density glue-logic migration, or Lattice ispMACH 4000ZE (256 macrocells, TQFP-144). For new 50K-gate designs, all major vendors recommend their modern families: Xilinx Artix-7, Lattice ECP5, or Microsemi IGLOO2.

What is the JTAG BSDL file name for EP1K50TI144-3N?

Altera published JTAG BSDL files for the ACEX 1K family under the prefix "ep1k50" with package and speed-grade suffixes. According to Altera's BSDL archive, the BSDL file for EP1K50TI144-3N is typically named ep1k50_tqfp144.bsd and is bundled with the Quartus II toolchain. Third-party BSDL aggregators also host it under the Altera ACEX 1K device family. The file supports IEEE 1149.1 boundary-scan test including INTEST, EXTEST, SAMPLE/PRELOAD, and BYPASS instructions.

انتخاب کی گائیڈ

Choose EP1K50TI144-3N when you need a 50K-gate industrial-temperature FPGA in a Pb-free 144-pin TQFP with the fastest ACEX 1K speed grade. This part is the right pick for new industrial, telecom, or test-and-measurement designs that require -40 to +85 °C operation and RoHS compliance. Choose EP1K50TI144-2N if you can accept ~133 MHz internal clock and want ~15% cost savings - drop-in identical pinout. Choose EP1K50TC144-3N only for commercial-temperature (0-70 °C) designs to save cost; it is NOT a substitute where industrial temp is required. Choose EP1K30TI144-3N when your design only needs 30K gates / 1,728 LEs / 72 I/O and you want to free up unused resources for power savings. For new designs with no legacy constraint, evaluate Cyclone IV E (EP4CE6/10) or MAX 10 (10M02/04) in EQFP-144 - they require a PCB re-spin but offer 5-10× lower static power and free Quartus Prime Lite toolchain support.

ڈیزائن نوٹس

ACEX 1K devices require separate VCCINT (2.5 V core) and VCCIO (2.5 V / 3.3 V / 5 V multiVolt I/O) planes. Place one 100 µF tantalum plus 0.1 µF ceramic per VCCINT pin pair, and one 0.1 µF ceramic per VCCIO bank. Power-up sequencing requires VCCINT before VCCIO; failure to observe this can cause latch-up. The ICCINT typical value is in the 5-50 mA range depending on utilization, while I/O supply current scales with switching frequency and load - estimate 5 mA per bank at 50 MHz.

The 144-pin TQFP has a 0.5 mm pitch and 22 mm x 22 mm body. Use 4-layer PCB with continuous power and ground planes, and route all 102 user I/O on inner layers to escape the dense perimeter. Place the EPC8 or EPC16 configuration PROM within 25 mm of the FPGA to minimize passive-serial stub length. JTAG chain length should not exceed 150 mm without a buffer; include a JTAG header for ByteBlasterMV / USB-Blaster programming.

ACEX 1K is SRAM-volatile: a configuration bitstream must be loaded at every power-up from an external serial PROM (EPC2/4/8/16) or a microprocessor. Do NOT use ACEX 1K as a substitute for MAX 7000/3000 CPLDs in designs that need instant-on operation - configuration time is 50-200 ms. Also verify that all unused I/O pins are set to 'tri-stated input with weak pull-up' in the Quartus pin-assignment file; floating outputs can cause 5-10 mA I/O bank current draw.

Estimated: at 50% logic utilization with 50% toggle rate, the EP1K50TI144-3N dissipates approximately 0.5 W. The TQFP-144 has theta_JA around 35 °C/W on a 4-layer JEDEC test board, giving junction temperature rise of ~17 °C above ambient. Industrial-temperature designs are comfortable at 70 °C ambient without a heatsink; for sealed enclosures above 85 °C, attach a small 10 mm x 10 mm copper pad or thermal adhesive pad to the package top.

Differential pairs (LVDS) on ACEX 1K require matched-length routing within 50 mil tolerance; route each pair on the same layer with no vias. Single-ended 5 V inputs use the LVTTL/LVCMOS 5V I/O standard and require 3.3 V VCCIO bank - never connect 5 V signals to a bank with VCCIO < 3.0 V. Clock inputs (CLK0/CLK1) should be routed first, length-matched, and terminated with 33 Ω series resistor at the FPGA pin if driving from a long trace.
