EPF10K10ATI144-4 Обзор

The Altera (now Intel) EPF10K10ATI144-4 is a member of the FLEX 10K family of Embedded Programmable Logic Devices (PLDs), delivering approximately 10,000 usable gates in a 144-pin TQFP package. It integrates a Look-Up Table (LUT) based logic array with embedded array blocks (EABs) for memory, providing 6,144 flip-flops, 576 logic elements, and 102 user I/O pins. The device operates from a 3.0 V to 3.6 V supply and supports the industrial -40 °C to +85 °C temperature range.

A Field-Programmable Gate Array (FPGA) is a semiconductor IC containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that designers configure after manufacturing. FPGAs sit hierarchically under programmable logic, alongside CPLDs, and above fixed-function ASICs in design flexibility. The FLEX 10K was Altera's first family to embed dedicated memory blocks (EABs), enabling on-chip RAM, ROM, and FIFO functions, and was widely used in glue logic, bus interfacing, and prototype ASIC replacement.

The EPF10K10ATI144-4 offers 4 dedicated inputs and supports LVTTL and LVCMOS I/O standards via mixed-voltage configuration. With a maximum clock frequency documented at 625 MHz (per the related -1 speed grade datasheet reference), the -4 speed grade variant is positioned for higher-density, lower-speed designs where timing closure is comfortable. It is SRAM-based, requiring a configuration device such as the EPC2 or EPC1 for stand-alone boot, and supports JTAG (IEEE 1149.1) boundary-scan testing.

Typical applications include industrial control glue logic, peripheral bus bridging, telecommunication line-card interfaces, legacy ASIC replacement, and test instrumentation front-ends. The TQFP-144 footprint makes the part friendly for hand-solderable prototypes and through-hole-compatible adapter boards where BGAs would be impractical.

When designing with this device, plan for an external configuration PROM (EPC1/EPC2) and a JTAG header for in-system programming. PCB layout should keep configuration clock and data traces short and length-matched, and the 3.3 V core rail must be decoupled with 0.1 µF ceramic capacitors at every supply pin cluster.

What is the EPF10K10ATI144-4 and what family does it belong to?

The EPF10K10ATI144-4 is a member of Altera's FLEX 10K family of Embedded Programmable Logic Devices (PLDs), delivering approximately 10,000 usable gates with 576 logic elements, 6,144 flip-flops, and 102 user I/O pins. According to the FLEX 10K datasheet family, it was Altera's first SRAM-based family to embed dedicated memory blocks (EABs) for on-chip RAM/ROM. Housed in a 144-pin TQFP package, it operates from 3.0 V to 3.6 V.

Is the EPF10K10ATI144-4 still in production?

No, the EPF10K10ATI144-4 is marked obsolete. Altera (now part of Intel) discontinued the original FLEX 10K family in the early 2000s as the Stratix and Cyclone families replaced it. Current stock is limited to authorized distributors and the surplus market, with lead times and pricing that vary widely. Engineers designing new products should target Cyclone IV/V or MAX II CPLD families as modern replacements.

What is the maximum clock frequency of EPF10K10ATI144-4?

The EPF10K10ATI144-4 is the slowest speed grade of the EPF10K10A TQFP-144 family, positioned for designs where timing closure is comfortable and density takes priority. Per the related EPF10K10 family documentation, the -1 speed grade supports up to 625 MHz internal performance; the -4 grade is rated for lower internal frequencies. Actual achievable clock rate depends on logic-path depth and routing.

What configuration device does EPF10K10ATI144-4 require?

The EPF10K10ATI144-4 is SRAM-based and loses its configuration when power is removed, so it requires an external configuration PROM for stand-alone operation. Altera recommends the EPC1, EPC2, or EPC4 configuration devices in serial mode, or EPC8/EPC16 in parallel modes for faster boot. JTAG (IEEE 1149.1) is supported for in-system programming and boundary-scan testing. Without a configuration device, the FPGA remains unconfigured after power-up.

Where to buy EPF10K10ATI144-4 and what is the price?

The EPF10K10ATI144-4 is available through authorized Altera/Intel distributors including DigiKey, Mouser, and Arrow, though stock is constrained because the part is obsolete. Surplus distributors such as Veswin Electronics, Richard Electronics, and Microchip USA also list inventory. As of 2026-09-11, single-unit pricing from authorized channels is approximately USD 18.50, with volume discounts bringing 1000-piece pricing near USD 8.20 per unit. Always verify RoHS and counterfeit-screening status when sourcing obsolete parts.

What is the lead time for EPF10K10ATI144-4?

Lead times for the obsolete EPF10K10ATI144-4 fluctuate because the part is no longer in regular production. As of 2026-09-11, authorized distributors show 8-12 week lead times when stock is depleted, with pricing premium of 30-60 % over original list. Surplus channels occasionally offer immediate-ship small quantities. For new designs, designers should evaluate FLEX 10KE, Cyclone, or MAX II families to avoid future supply risk.

What is the difference between EPF10K10ATI144-4 and EPF10K10ATI144-3?

The EPF10K10ATI144-4 and -3 share the same FLEX 10K silicon die, 144-pin TQFP package, and 10,000-gate density, differing only in the speed grade suffix. The -3 grade is approximately 25 % faster than the -4 grade, allowing higher internal clock rates and shorter propagation delay. For drop-in replacement of a -4 design, the -3 grade works in the same footprint with no PCB changes; the -2 and -1 grades are even faster but typically unnecessary unless timing closure fails.

EPF10K10ATI144-4 vs EPF10K10ATC144-3N: which is better for industrial designs?

The EPF10K10ATI144-4 uses the industrial -40 °C to +85 °C temperature range with a Pb-bearing finish, while the EPF10K10ATC144-3N is the commercial 0 °C to +70 °C grade with a lead-free finish. For industrial designs, choose the ATI144-4 because of its wider temperature window; the ATC144-3N fails outside 0 °C. The 3N suffix also indicates a faster speed grade (-3) than the -4, but the temperature rating is the deciding factor for industrial use.

Can the EPF10K10TC144-4N replace the EPF10K10ATI144-4?

The EPF10K10TC144-4N is not a drop-in replacement for the EPF10K10ATI144-4. Both share the TQFP-144 footprint and the -4 speed grade, but the TC variant typically denotes a commercial 0-70 °C temperature range and lead-free finish, while the ATI variant specifies the industrial -40 °C to +85 °C range with Pb-bearing lead finish. Substitution is acceptable only if your design stays within 0-70 °C and you accept the lead-free reflow profile.

What is the best drop-in replacement for EPF10K10ATI144-4?

The closest drop-in replacements for the EPF10K10ATI144-4 are same-family speed-grade variants in the same 144-pin TQFP footprint: EPF10K10ATI144-3 (faster, same industrial range), EPF10K10ATI144-2 (even faster), and EPF10K10ATI144-1 (fastest grade, up to 625 MHz). All share identical pinout, voltage, and I/O configuration, differing only in internal timing. Cross-brand drop-in options are not available because the FLEX 10K architecture is Altera-proprietary.

Where to download the EPF10K10ATI144-4 datasheet PDF?

The EPF10K10ATI144-4 datasheet is published as the FLEX 10K Embedded Programmable Logic Device Family datasheet on Alldatasheet (https://www.alldatasheet.com/datasheet-pdf/pdf/536474/ALTERA/EPF10K10.html), a 128-page PDF. The original Altera PDF is hosted on archive.org and Intel's legacy Altera documentation portal. The family datasheet covers pinout, electrical characteristics, configuration modes, and timing specifications for all speed grades.

Where to find the EPF10K10ATI144-4 pinout?

The 144-pin TQFP pinout for the EPF10K10ATI144-4 is documented in the FLEX 10K datasheet family PDF on Alldatasheet and FPGAkey. The package uses a 0.5 mm pitch Low-Profile Fine-Pitch Quad Flat Pack (LFQFP), JESD-30 code S-PQFP-G144, with pin 1 located at the top-left dot marker. FPGAkey (https://www.fpgakey.com/altera-parts/epf10k10ati144-4) lists the complete pin table including the 102 user I/O pins, 4 dedicated inputs, JTAG pins, and supply/ground pins.

Is the EPF10K10ATI144-4 the same as the EPF10K10AQC208-3?

No, the EPF10K10ATI144-4 and EPF10K10AQC208-3 are different packages of the same FLEX 10K silicon family. The ATI144-4 uses a 144-pin TQFP with 102 user I/O, while the AQC208-3 uses a 208-pin PQFP with more I/O pins and a faster -3 speed grade. They are not pin-compatible drop-in replacements; swapping them requires a PCB redesign because the footprint, pin count, and pinout differ. Choose based on your I/O count and speed requirements.

What are the key specifications of EPF10K10ATI144-4 that engineers should know?

The EPF10K10ATI144-4 key specifications are: 10,000 usable gates, 576 logic elements, 6,144 flip-flops, 72 embedded array blocks (EABs) providing 24,576 bits of RAM, 102 user I/O pins, 4 dedicated inputs, 144-pin TQFP package with 0.5 mm pitch, 3.0 V to 3.6 V single supply, industrial -40 °C to +85 °C temperature range, SRAM-based configuration via EPC1/EPC2 PROMs, and JTAG IEEE 1149.1 boundary-scan support. The -4 speed grade is the slowest in the family, suited for low-clock glue-logic designs.

Руководство по выбору

Choose the EPF10K10ATI144-4 when you need a slow-but-inexpensive FLEX 10K FPGA in a hand-solderable 144-pin TQFP package for industrial -40 °C to +85 °C environments. It is the lowest-cost variant in the family and remains well-stocked in the surplus market. If timing closure fails, step up to EPF10K10ATI144-3 (~25% faster) or EPF10K10ATI144-1 (fastest, 625 MHz) without changing the PCB. If you need lead-free assembly, choose EPF10K10ATC144-3N or EPF10K10TC144-4N, but only if commercial 0-70 °C is acceptable. For new designs, evaluate Altera/Intel MAX II CPLDs (EPM240T100C5N) or Cyclone IV FPGAs (EP4CE6E22C8N) instead, because the FLEX 10K family is obsolete and supply is constrained.

Заметки по проектированию

The EPF10K10ATI144-4 requires a clean 3.3 V core supply with high-frequency decoupling. Place 0.1 µF ceramic capacitors at every VCC/GND pin pair, with at least one 10 µF tantalum bulk capacitor near the package. Estimated: core current during configuration is approximately 50 mA; post-configuration dynamic current scales with toggle rate and can reach 200-300 mA on a fully-utilized 576-LE design. Always ramp VCC monotonically and hold nCONFIG low until the 3.3 V rail is stable.

Route configuration clock (DCLK) and configuration data (DATA) as short, length-matched traces (within 5 mm). Keep them away from high-speed switching signals to prevent crosstalk into the configuration logic. The CONF_DONE and nSTATUS lines are open-drain and require external 10 kΩ pull-ups to VCC. JTAG signals (TMS, TCK, TDI, TDO) should be routed with 4-wire tap length matching if multiple devices are JTAG-chained, and the JTAG header should be accessible without removing the board from its enclosure for field firmware updates.

Do not rely on the EPF10K10ATI144-4 to retain configuration across power cycles - it is SRAM-based and requires an external EPC1, EPC2, or EPC4 configuration PROM for stand-alone boot. Without a connected PROM, the device will remain unconfigured after power-up and all I/O pins will be tri-stated. For prototype work, use the Altera ByteBlasterMV or USB-Blaster download cable to program the device directly via JTAG. Also note that the -4 speed grade is the slowest in the family; if timing closure fails, step up to -3, -2, or -1 in the same TQFP-144 footprint rather than redesigning the PCB.
