EPF10K30ETI144-2 概覽

The Intel (formerly Altera) EPF10K30ETI144-2 is a member of the FLEX 10KE embedded programmable logic family, integrating approximately 30,000 typical gates, 1,728 logic elements, and 24,576 bits of embedded array memory (EABs) in a 144-pin TQFP package. As a 2.5 V core SRAM-based FPGA with 102 user I/Os and a -2 speed grade, it targets glue-logic, bus-interface, and embedded control designs that benefit from on-chip dual-port RAM blocks for FIFO and register-file functions.

What is an FPGA? A Field Programmable Gate Array (FPGA) is a semiconductor IC containing an array of configurable logic blocks (CLBs/LABs), programmable routing, and I/O cells that the designer can wire up after manufacture to implement arbitrary digital circuits. FPGAs sit in the broader hierarchy: programmable logic device (PLD) -> FPGA -> SRAM-based FPGA -> embedded-block FPGA. The FLEX 10KE family added Embedded Array Blocks (EABs) so each block can act as dual-port RAM, ROM, or a multiplier-style lookup - the 'embedded' name comes from this on-chip memory integration rather than a hard processor core.

Key features include 216 Logic Array Blocks (LABs), 102 maximum user I/O pins, an internal operating frequency up to 200 MHz, and CMOS logic family operation. The 144-pin TQFP (Thin Quad Flat Pack) surface-mount package exposes JTAG-compliant configuration and supply rails at 2.375 V to 2.625 V, and supports in-system programmability via the Altera (now Intel) Quartus / MAX+PLUS II toolchain.

The EPF10K30E architecture combines a fine-grained logic fabric with coarse-grained EABs, giving designers block-RAM density similar to early SoC integration without leaving the PLD paradigm. Pin-compatible speed/grade variants (e.g., -3, -2, -1) allow timing tuning without PCB rework, while different packages (TQFP-144, QFP-208, BGA-256, BGA-484) of the same die give I/O-count flexibility across board revisions.

Typical applications include industrial control glue logic, telecom line-card bus bridges, legacy peripheral emulation, prototyping of ASIC logic, and embedded DSP datapaths where the EABs can implement small multiply-accumulate tables. The industrial temperature grade (-40C to +85C inferred from the 'I' suffix) suits factory-floor and outdoor enclosures.

When designing, plan for I/O bank voltage compatibility, leave the JTAG chain accessible for factory programming, and pair the EPF10K30E with a configuration PROM (EPCS or EPC2) for standalone boot. Note that the FLEX 10KE family is mature/legacy - check Intel's product longevity program for current supply status before new designs.

典型應用

EPF10K30ETI144-2 適用於 6 應用s: Industrial Glue Logic / Bus Bridge, Legacy Peripheral Emulation, Telecom Line-Card Glue Logic, ASIC Prototyping and Logic Validation, Embedded DSP / Multiply-Accumulate Tables, Test & Measurement Front-End Logic.

🏭

Industrial Glue Logic / Bus Bridge

The EPF10K30ETI144-2 fits industrial glue-logic boards that bridge legacy parallel buses (ISA, PC/104, VME) to modern microprocessors. With 1,728 logic elements and 102 user I/Os, the FPGA can implement multi-master bus arbiters, address decoders, and 8/16/32-bit FIFO bridges in a single chip. The 24,576 bits of EAB RAM provide true dual-port memory for mailbox and pointer-passing between bus masters. Industrial temperature grade (-40C to +85C) ensures operation in factory-floor enclosures without derating. Quartus synthesis fits typical 32-bit bus-bridge designs well within the 30K-gate budget.

🖥️

Legacy Peripheral Emulation

Emulating discontinued peripherals (parallel-port chips, custom DMA controllers, ISA cards) is a sweet spot for the EPF10K30ETI144-2. The 200 MHz internal frequency easily handles ISA-bus timing, while 102 user I/Os are sufficient for 16-bit data plus full control-signal reproduction. EAB blocks can implement wait-state generators and protocol state machines. Designers maintain a single bitstream per peripheral, so the same PCB can emulate multiple legacy devices by re-flashing the configuration PROM - useful in aerospace and military long-lifecycle programs.

🌐

Telecom Line-Card Glue Logic

Telecom line cards use the EPF10K30ETI144-2 for backplane glue, TDM bus arbitration, and HDLC/framer interfacing where deterministic latency matters. The FLEX 10KE fabric gives sub-10 ns pin-to-pin delays suitable for E1/T1 and 8 MHz ST-BUS clocks, while 102 I/Os cover 16-bit data plus framing and clock signals. Industrial temperature rating suits outdoor cabinet deployments. EABs implement small lookup tables for codec-law conversion (A-law/mu-law) without external ROM.

ASIC Prototyping and Logic Validation

Before taping out an ASIC, designers validate RTL on FPGAs - the EPF10K30ETI144-2 fits small SoC blocks such as interrupt controllers, DMA engines, custom peripherals, and AMBA-AHB-to-APB bridges. 30K gates accommodate ~5-10K gate-equivalent ASIC logic with reasonable timing margin. Quartus synthesis with the FLEX 10KE library lets engineers reuse the same RTL later on Cyclone IV for production without rewriting constraints. Industrial temp grade supports in-vehicle and outdoor validation campaigns.

Embedded DSP / Multiply-Accumulate Tables

Each FLEX 10KE EAB can be configured as a small read-only or read/write memory that mimics a multiplier lookup table - the EPF10K30ETI144-2 therefore fits low-sample-rate DSP datapaths (control loops, codec post-processing, simple FIR filters) where lookup-table-based MAC units suffice. 24,576 EAB bits hold 4K x 6-bit or 2K x 12-bit coefficient tables, and the 200 MHz fabric supports multi-MHz sample streams in industrial temperature environments.

🧪

Test & Measurement Front-End Logic

Test equipment designers use the EPF10K30ETI144-2 for pattern generation, timing sequencers, and instrument-switching matrices. The 102 I/O count is sufficient for 32-channel digital I/O cards, and the 2.5 V core plus JTAG configuration support production-line programming via standard Altera tools. Industrial temperature grade suits bench and chamber testing. EAB RAM acts as a deep pattern buffer, and the 144-TQFP package is hand-solderable for prototype builds.

What is the EPF10K30ETI144-2?

The EPF10K30ETI144-2 is an Intel (formerly Altera) FLEX 10KE family SRAM-based FPGA with 30,000 typical gates, 1,728 logic elements, 24,576 bits of embedded array memory, and 102 user I/Os, housed in a 144-pin TQFP package. The 'E' suffix marks the embedded-array (EAB) generation of the FLEX 10K lineage, while '-2' is the speed grade.

How many user I/O pins does the EPF10K30ETI144-2 have?

The EPF10K30ETI144-2 provides 102 maximum user I/O pins on its 144-pin TQFP package, with the remaining pins assigned to power, ground, JTAG, and configuration. This I/O count suits bus-bridge, glue-logic, and small peripheral-controller designs where 80-100 signals need to be routed off-chip.

What is the supply voltage of EPF10K30ETI144-2?

The EPF10K30ETI144-2 operates from a 2.5 V core supply with a tolerated range of 2.375 V to 2.625 V, per the FLEX 10KE datasheet. I/O banks can typically be powered at 3.3 V for TTL/PCI-compatible signaling; verify the bank supply range against the latest Altera/Intel datasheet before mixing voltages.

What is the difference between EPF10K30ETI144-2 and EPF10K30ETC144-2?

The EPF10K30ETI144-2 is the industrial temperature grade (-40C to +85C) variant of the FLEX 10KE 30K-gate FPGA, while the EPF10K30ETC144-2 is the commercial grade (0C to +70C). Both share the same 144-TQFP package and -2 speed grade, making the EPF10K30ETI144-2 a drop-in upgrade for designs that need industrial temperature operation.

Is EPF10K30ETI144-2 still in production?

As of 2026-09-11 the EPF10K30ETI144-2 is in the Intel/Altera FLEX 10KE mature-product program with limited/NRND availability - distributors such as Digikey, Mouser, and Arrow show active stock but Intel has consolidated newer designs onto Cyclone series. Check the Intel product longevity page and authorized distributors for current lead times before committing to a new design.

Where can I download the EPF10K30ETI144-2 datasheet PDF?

The official FLEX 10KE family datasheet is hosted by Intel at intel.com under the legacy Altera documentation archive - search the part number on intel.com or use the alldatasheet/archive mirrors. The datasheet covers electrical characteristics, timing, configuration, and pinout for all FLEX 10KE package variants including the 144-pin TQFP.

What configuration device does EPF10K30ETI144-2 use?

The EPF10K30ETI144-2 supports multiple configuration modes including JTAG, serial (PS), and parallel (PPA/PPC) modes, and is typically paired with an EPC2, EPCS1, or EPCS4 configuration PROM. For new designs Intel recommends the EPCS-series serial flash; for legacy retrofit, an EPC2 parallel EEPROM works equally well in PS mode.

Can EPF10K30ETI144-2 be replaced by EPF10K30ATC144-2?

The EPF10K30ATC144-2 (commercial grade) shares the 144-TQFP footprint of the EPF10K30ETI144-2 but is specified for 0C to +70C instead of -40C to +85C, so it is only a drop-in replacement in commercial-temperature applications. For industrial or outdoor designs, choose an industrial-grade equivalent such as EPF10K30ATI144-2 or pin-compatible FLEX 10KE 30K variants.

EPF10K30ETI144-2 vs Cyclone - which is better for new designs?

For new designs in 2026, the Intel Cyclone IV/V family is a better long-term choice than EPF10K30ETI144-2: lower core voltage (1.2 V typical), higher logic density per dollar, free Quartus Prime support, and active production. However, the EPF10K30ETI144-2 remains a practical choice for legacy board replication, repair, and designs that already have a verified FLEX 10KE bitstream.

What is the price of EPF10K30ETI144-2?

Because the part is in the Intel mature/NRND program, designers should qualify a secondary source such as EPF10K30ATI144-2 from the start.

What is the lead time for EPF10K30ETI144-2?

Lead time for EPF10K30ETI144-2 from authorized distributors is typically 8-12 weeks as of 2026-09-11, given its mature/NRND status in the Intel product longevity program. Brokers and franchised distributors on Octopart sometimes show shorter lead times at higher unit cost. For production designs, place a safety-stock order or qualify a Cyclone IV equivalent.

What is the best cross-brand equivalent for EPF10K30ETI144-2?

There is no true cross-brand drop-in equivalent for EPF10K30ETI144-2 because FLEX 10KE is an Altera/Intel proprietary architecture with unique JTAG, configuration, and bitstream formats. Cross-brand FPGAs in the 30K-gate class from Xilinx (XC95144XL) or Lattice (ispMACH 4000ZE) require full bitstream re-development and PCB rework - treat them as functional equivalents, not drop-ins.

What are the key specifications of EPF10K30ETI144-2 that engineers should know?

The EPF10K30ETI144-2 specifies 30,000 typical gates, 1,728 logic elements, 216 LABs, 24,576 RAM bits, 102 user I/O, 2.5 V core (2.375-2.625 V), industrial temperature grade -40C to +85C, 200 MHz internal frequency, 144-pin TQFP surface-mount package, and a -2 speed grade per the FLEX 10KE datasheet family document. These figures determine the FPGA's logic capacity, I/O fan-out, and thermal envelope.

選型指南

Choose EPF10K30ETI144-2 when you need an industrial-temperature (-40C to +85C) FLEX 10KE FPGA in the 144-TQFP package for legacy designs, repair, or new industrial glue-logic boards. Choose EPF10K30ETC144-2 (commercial temp) for cost-sensitive indoor designs or prototypes. Choose EPF10K30ATC144-3 if your timing budget requires the faster -3 speed grade. Choose EPF10K30ATI144-2 as a second-source drop-in identical part. For brand-new 2026 designs, consider Intel Cyclone IV EP4CE30F23C8N - it is not pin-compatible (requires PCB rework) but offers much lower power and active production support. Within the FLEX 10KE family, all six alternatives above share the 144-TQFP footprint and the same Quartus bitstream format, so a single PCB layout supports multiple temperature/speed-grade options.

設計說明

The EPF10K30ETI144-2 requires a stable 2.5 V core rail (2.375 V to 2.625 V) and one or more VCCIO bank supplies (typically 3.3 V for TTL/PCI-compatible I/O). Place 0.1 uF decoupling capacitors as close as possible to every VCCINT and VCCIO pin, and add bulk 10-47 uF tantalum or ceramic capacitors at each power-supply entry point. The SRAM-based configuration means inrush can reach 500 mA during configuration; size the regulator accordingly. Power sequencing - core before VCCIO, or simultaneous - is acceptable per Altera/Intel documentation.

Route the JTAG chain (TCK, TMS, TDI, TDO) with a star topology from the JTAG header to each device and keep TCK trace under 6 inches to avoid signal-integrity issues. Expose nCONFIG, nSTATUS, and CONF_DONE for in-system programming access. The 144-pin TQFP has a 0.5 mm pitch - use 0.15 mm trace/space with a 4-layer PCB and a continuous ground plane under the package. Leave 4-6 ground vias in the package thermal slug area for thermal dissipation.

Estimated: configuring the EPF10K30ETI144-2 from a fresh board without checking MSEL0/MSEL1 strap pins is the #1 first-power-on failure mode - tie them to the correct logic level for PS or JTAG mode before applying power. Second common pitfall: leaving VCCIO banks at 2.5 V while driving 3.3 V peripheral signals - this damages the I/O cells. Third: failing to series-terminate high-speed clock-distribution outputs when driving long traces; add 33 ohm series resistors at the FPGA output. Finally, choose EPCS-series serial flash only with Quartus version 7.2 or later for proper SOF-to-POF support.

Estimated: at 200 MHz internal frequency with 80% logic utilization, the EPF10K30ETI144-2 dissipates roughly 0.5-0.8 W typical, 1.5 W maximum. The 144-pin TQFP thermal resistance is approximately 35 C/W theta_JA on a 4-layer PCB with a small ground pad, so junction temperature rise above ambient is roughly 18-28 C typical, 53 C max - within industrial-grade limits. For continuous 85 C ambient operation, ensure 4-layer PCB with 2 oz copper pours on core and I/O supply planes to keep junction below 125 C.
