EPF10K30EQI208-3 概覽
The Intel (formerly Altera) EPF10K30EQI208-3 is a FLEX 10KE family Field Programmable Gate Array delivering approximately 30,000 equivalent ASIC gates, 1,728 logic elements, and 24,576 RAM bits in a 208-pin Power-QFP (BFQFP, RQ208) package. It provides 147 user I/O pins, a 12.5 ns pin-to-pin propagation delay, and operates from a nominal 2.5 V core supply across the industrial -40C to +85C temperature range. The device is built on a 0.22 um CMOS SRAM process with embedded array architecture.
What is an FPGA? A Field Programmable Gate Array is a reprogrammable semiconductor device whose logic functionality is defined by user-loaded configuration bitstreams rather than hard-wired mask layers. FPGAs sit in the broader hierarchy programmable logic device (PLD) -> CPLD -> FPGA -> programmable SoC, and they integrate configurable logic blocks (LEs), embedded array blocks (EABs), programmable interconnect, and I/O elements on a single die. The FLEX 10KE family was Altera's second-generation embedded-array SRAM FPGA line, designed for moderate-density glue logic, bus interfacing, and small state-machine consolidation.
Key features include 1,728 logic elements (LEs), six Embedded Array Blocks providing 24,576 bits of synchronous dual-port RAM, MultiVolt I/O supporting 2.5 V, 3.3 V, and 5.0 V interfaces on the same die, in-system programmability via the serial passive or JTAG configuration chain, and four Low-Skew Clock networks. The on-chip EABs can be configured as 256x8, 512x4, 1024x2, or 2048x1 memory blocks and are also usable as product-term logic arrays for wide fan-in functions.
Technical depth: The FLEX 10KE architecture uses a continuous, segmented routing fabric with FastTrack Interconnect, allowing predictable timing closure for designs up to ~30K gates. The device supports IEEE 1149.1 boundary-scan test and 4 mA drive strength per I/O with slew-rate control. The -3 speed grade is the fastest commercial grade available for this family, optimizing for synchronous datapath throughput rather than area efficiency.
Typical applications for the EPF10K30EQI208-3 include telecom line-card glue logic, peripheral bus bridges (PCI to local bus), industrial motor-control and PLC interface boards, and legacy equipment retrofits. The 208-pin PQFP footprint also made the device common in 1990s-vintage networking and instrumentation gear that is now being redesigned for long-life-cycle support.
Design consideration: When designing with this part, ensure your configuration bitstream is stored in a compatible PROM (EPC2, EPC8, or EPC16) or loaded via JTAG at power-up, because the SRAM-based FLEX 10KE loses its configuration on every power-down. The MultiVolt I/O bank requires separate VCCIO rails for mixed-voltage interfacing; do not tie VCCIO directly to VCCINT.
This page synthesizes distributor pricing, drop-in alternative MPNs from the same Altera FLEX 10KE family, and practical design notes not consolidated in the original manufacturer datasheet, giving engineers a faster path to source this mature FPGA for new builds and legacy redesigns.

EPF10K30EQI208-3 適用於 6 應用s: Telecom Line-Card Glue Logic, Peripheral Bus Bridge (PCI / ISA to Local Bus), Industrial Motor-Control and PLC Interface, Legacy Test and Measurement Instrumentation, Aerospace and Defense Avionics Retrofit, Networking Router/Switch Line-Card Aggregation.
Telecom Line-Card Glue Logic
The EPF10K30EQI208-3's 1,728 logic elements and 147 user I/O pins make it well suited for telecom line-card glue-logic consolidation, where it can replace multiple discrete PAL/GAL devices with a single reprogrammable part. Its 12.5 ns propagation delay in the -3 speed grade comfortably meets T1/E1 framer interface timing. The embedded 24,576-bit RAM array is sufficient to implement small FIFO buffers, look-up tables, and protocol-state machines used in channel-associated signalling. MultiVolt I/O allows direct interface to 3.3 V and 5.0 V framers without level shifters. Industrial temperature grading and surface-mount PQFP packaging suit central-office equipment that must operate 24/7 for decades.
推薦
Peripheral Bus Bridge (PCI / ISA to Local Bus)
The EPF10K30EQI208-3 is widely deployed as a peripheral bus bridge between legacy PCI or ISA buses and proprietary local buses on industrial motherboards. The 147 I/Os are sufficient to implement full 32-bit PCI master/target interfaces with parity, while the 6 EABs provide 24Kbits of dual-port RAM for transaction buffering. The 12.5 ns propagation delay enables 33 MHz PCI operation in the -3 grade. Embedded array architecture allows the same silicon to be reconfigured for different target bus protocols via bitstream swap. This application benefits from FLEX 10KE's robust MultiVolt I/O, which can mix 5 V PCI signalling with 3.3 V local-bus logic on the same die.
推薦
Industrial Motor-Control and PLC Interface
The EPF10K30EQI208-3's industrial temperature rating (-40C to +85C) and robust 208-PQFP package make it suitable for industrial motor-control and PLC interface boards. With 1,728 LEs, it can implement multi-axis PWM generators, quadrature decoder logic, encoder-interface state machines, and CAN/RS-485 bus bridges simultaneously. The 24Kbit embedded RAM supports capture buffers and trajectory look-up tables for servo loops. The 147 I/O pins easily accommodate multi-axis encoder inputs plus drive-enable outputs. SRAM-based configuration allows field reconfiguration for firmware upgrades over JTAG without removing the board from service.
推薦
Legacy Test and Measurement Instrumentation
In legacy test and measurement instruments such as bench-top oscilloscopes, logic analyzers, and protocol analyzers, the EPF10K30EQI208-3 serves as the central pattern-generator and timing-controller. Its 12.5 ns propagation delay and 909 MHz internal toggle rate allow direct synthesis of 40 MHz clock patterns and complex stimulus sequences. The 6 embedded array blocks provide 24Kbits of capture memory for logic-analyzer front-ends. The 208-PQFP package is easy to hand-rework on older through-hole-and-SMT-mix assemblies, simplifying field service. Long product life cycles in the T&M market (often 10-20 years) align with the FLEX 10KE family's mature-node reliability profile.
推薦
Aerospace and Defense Avionics Retrofit
The EPF10K30EQI208-3 is found in aerospace and defense avionics retrofit programs, where its industrial temperature range and MIL-STD-883 screening options make it suitable for harsh-environment cockpit and mission-computer upgrades. With 1,728 LEs, it can implement ARINC 429 / MIL-STD-1553 bus interfaces, discrete I/O expansion, and timing-synchronization logic. The 147 I/O pins handle multiple serial databuses plus parallel avionics discretes in a single device. The 208-PQFP package is mechanically robust and compatible with through-hole-style rework tools used in depot-level maintenance. Legacy long-lifecycle programs that cannot migrate to RoHS-only parts may continue to specify this device from LTB stock.
推薦
Networking Router/Switch Line-Card Aggregation
In legacy networking line cards, the EPF10K30EQI208-3 is commonly deployed as a packet-classification and queue-management co-processor alongside a network processor. Its 147 I/Os are sufficient to expose multiple SPI/UART/I2C management interfaces plus an 8-bit UTOPIA/POSPHY-style fabric interface. The 24Kbit EAB RAM supports small CAM emulations and statistics counters. The 12.5 ns propagation delay in -3 speed grade handles 50 MHz fabric-side clocks with comfortable margin. MultiVolt I/O lets the same device interface to 5 V legacy transceivers and 3.3 V ASICs without external level shifters. SRAM-based configuration enables per-linecard personality via factory-loaded bitstreams.

What is the logic capacity of EPF10K30EQI208-3?
The EPF10K30EQI208-3 delivers approximately 30,000 equivalent ASIC gates organized as 1,728 logic elements (LEs), with six Embedded Array Blocks (EABs) providing 24,576 bits of synchronous dual-port RAM. This places it in the moderate-density tier of the Altera FLEX 10KE family. According to the Altera FLEX 10KE datasheet, the device targets glue-logic consolidation, peripheral bridging, and small state-machine integration rather than high-density datapath designs.
What package does the EPF10K30EQI208-3 use?
The EPF10K30EQI208-3 ships in a 208-pin Power-QFP package (BFQFP / RQ208) with gull-wing surface-mount leads. Pin 1 is located at the corner marked by the dot. According to the FLEX 10KE datasheet, the 208-PQFP variant exposes 147 user I/O pins, leaving the remaining pins for JTAG, configuration, power, and ground. The package is now considered legacy footprint and is being phased out across most distributors.
Is the EPF10K30EQI208-3 still in production?
The EPF10K30EQI208-3 is currently classified as Last Time Buy (LTB) by Intel PSG, with new orders accepted only until the published LTB date and final deliveries scheduled thereafter. The underlying FLEX 10KE family is part of Intel's mature-node FPGA portfolio that has been progressively superseded by Cyclone, MAX, and Agilex device families. Existing designs should plan a migration path before the LTB window closes.
What is the difference between EPF10K30EQI208-3 and EPF10K30EQC208-3?
The EPF10K30EQI208-3 is the industrial-temperature (-40C to +85C) variant in a 208-pin Industrial-PQFP, while the EPF10K30EQC208-3 is the commercial-temperature (0C to +70C) variant in a 208-pin Commercial-PQFP. Both share the same FLEX 10KE silicon die and 30K-gate capacity. The EQI vs EQC suffix encodes both temperature grade and speed grade; the 'I' suffix denotes industrial and 'C' denotes commercial.
What is the propagation delay of EPF10K30EQI208-3?
The EPF10K30EQI208-3 is rated at 12.5 ns pin-to-pin propagation delay in its -3 speed grade, which is the fastest speed grade offered for this part. Maximum toggle frequency is 909.09 MHz for internal logic. Speed grades of -2 and -1 are also available in the FLEX 10KE family, with progressively longer propagation delays of approximately 15 ns and 20 ns respectively. The -3 grade optimizes synchronous datapath throughput at the cost of higher dynamic power.
How do you configure the EPF10K30EQI208-3 at power-up?
The EPF10K30EQI208-3 is SRAM-based and must be configured at every power-on via the dedicated serial passive configuration chain or the JTAG (IEEE 1149.1) interface. According to Altera's configuration handbook, designers typically pair this device with an EPC2, EPC8, or EPC16 configuration PROM, or load the bitstream from a microcontroller through JTAG. Power-on reset timing must satisfy the 2.5 V VCCINT rise-time requirement before configuration begins.
Can EPF10K30EQI208-3 be replaced by a modern Altera/Intel FPGA?
Drop-in pin-compatible replacements within the FLEX 10KE family are limited, but functionally-equivalent modern replacements exist in the Intel Cyclone series. Cyclone IV EP4CE30 in F256 or similar BGA packages provides approximately the same LE count and more on-chip resources, but requires a PCB re-layout because the 208-PQFP footprint is not preserved. Engineers should treat this as a board redesign, not a drop-in swap. For true pin compatibility within the 208-PQFP, alternative FLEX 10KE speed-grade variants remain the only practical option.
What is the best drop-in replacement for EPF10K30EQI208-3?
Within the 208-pin PQFP footprint, the closest drop-in replacements are same-package FLEX 10KE speed-grade and temperature-grade variants such as EPF10K30EQI208-2 and EPF10K30EQI208-1. These share the identical die and pinout but trade off propagation delay for cost. Cross-brand pin-compatible replacements in the same footprint do not exist, because no other vendor replicated the FLEX 10KE 208-PQFP pinout; modern pin-compatible alternatives require PCB rework.
What is the price of EPF10K30EQI208-3 in 2026?
As of September 2026, EPF10K30EQI208-3 unit pricing from authorized distributors ranges from approximately $38.50 at qty 1 down to about $19.80 at qty 1000, reflecting the LTB supply constraint and shrinking authorized-stock pool. Distributors such as DigiKey, Mouser, AIChipLink, and Nantian are showing stock counts in the low-hundreds rather than tens of thousands. Order-on-request quotes from independent brokers may differ significantly from these tier prices.
Where can I buy EPF10K30EQI208-3 online?
The EPF10K30EQI208-3 is currently stocked at DigiKey, Mouser, AIChipLink, Nantian, Micro-Semiconductor, and Vyrian. DigiKey (DigiKey part 6571285) and Mouser list the part under Intel's FPGA category. Independent brokers and salvage distributors also carry refurbished or factory-sealed stock; XAIPART offers matched inventory with cross-reference verification. Lead time on authorized-stock orders is typically 4-8 weeks as the LTB phase progresses.
What is the lead time for EPF10K30EQI208-3?
Authorized distributor lead time for EPF10K30EQI208-3 is currently 4-8 weeks as of September 2026, although last-time-buy stock can be exhausted without notice. According to the Intel PSG product change notification, last-time-buy orders must be placed before the published LTB cutoff date, with final deliveries scheduled 6-12 months after the LTB cutoff. Independent brokers can ship immediately but at higher unit cost and provenance risk.
Where do I download the EPF10K30EQI208-3 datasheet PDF?
The official Altera FLEX 10KE family datasheet (covering EPF10K30EQI208-3 and all package/speed variants) is hosted by Intel PSG at the Altera legacy documentation archive. The primary document is the FLEX 10KE Device Datasheet, which includes pinouts for the 208-PQFP, electrical characteristics, and timing models. Mirror copies are also available on components-store.com and through Intel's 'Altera Legacy' product support portal.
What is the pinout of EPF10K30EQI208-3 in 208-PQFP?
The 208-pin PQFP pinout for EPF10K30EQI208-3 is documented in the FLEX 10KE datasheet, with 147 dedicated user I/O pins, dedicated JTAG pins (TDI, TDO, TMS, TCK), configuration pins (nCONFIG, nSTATUS, CONF_DONE, MSELn, DCLK), four dedicated clock inputs (CLK0-CLK3), and power/ground pins (VCCINT, VCCIO, GND). The full pin assignment table is in section 8 of the FLEX 10KE datasheet. Engineers should reference the device-specific pinout file rather than the family pinout, because package-specific pinouts can shift I/O bank assignments.
Is EPF10K30EQI208-3 the same as EPF10K30AQI208-3?
No. The EPF10K30EQI208-3 belongs to the FLEX 10KE family (Embedded Array, ~30K gates, 1,728 LEs) while the EPF10K30AQI208-3 belongs to the FLEX 10KA family (older first-generation FLEX 10K architecture, ~30K gates, 1,728 LEs but with different EAB structure). Both share the 208-pin PQFP package, but the silicon die differs, so configuration bitstreams are NOT portable between the two.

選型指南
Choose EPF10K30EQI208-3 when you need an industrial-temperature (-40C to +85C) FLEX 10KE FPGA with the fastest -3 speed grade (12.5 ns) in a hand-rework-friendly 208-PQFP package. Choose EPF10K30EQI208-2 if your timing budget can accept ~15 ns propagation delay for cost savings. Choose EPF10K30EQC208-3 only for indoor commercial-temperature (0C to +70C) products where industrial grading is not required. Avoid mixing FLEX 10KE (E suffix) and FLEX 10KA (A suffix) bitstreams - they are not portable. For new designs not constrained by legacy 208-PQFP footprint, consider modern Cyclone IV EP4CE30 in BGA, but expect a full PCB redesign.

主要差異化特點

設計說明
The FLEX 10KE EPF10K30EQI208-3 requires separate VCCINT (2.5 V core) and VCCIO (2.5 V / 3.3 V / 5.0 V) rails with proper decoupling. According to Altera's configuration handbook, place 0.1 uF ceramic decoupling caps close to each VCCINT pin and bulk 100 uF tantalum or polymer caps per rail. Power-on sequencing requires VCCINT to rise monotonically before configuration begins; use a power-good supervisor to gate nCONFIG. MultiVolt I/O banks must be powered even when their I/O pins are unused, otherwise floating VCCIO pins can cause configuration failure.
The 208-pin PQFP package has 0.5 mm lead pitch with gull-wing leads and a thermal pad underneath (not exposed in this package variant). Per Altera layout guidelines, route all four dedicated clock inputs (CLK0-CLK3) with controlled 50 ohm impedance and length-matched within 1 cm of each other when used in the same clock domain. Keep JTAG chain traces (TDI, TDO, TMS, TCK) away from clock and high-speed I/O to avoid coupling noise into boundary-scan operation. Use a continuous ground plane under the device to minimize ground bounce during simultaneous-switching-output events.
Configuration bitstream portability is a frequent trap: the FLEX 10KE (E suffix) and FLEX 10KA (A suffix) families use different EAB architectures, so bitstreams generated for one are NOT compatible with the other even if pin-compatible in the same 208-PQFP footprint. Verify the silicon die suffix matches your Quartus project target. Also, SRAM configuration means the device loses its design at every power-down - always pair with a configuration PROM (EPC2, EPC8, or EPC16) or a microcontroller-driven JTAG loader for production deployment. Finally, do not drive JTAG signals before VCCINT is stable or the JTAG TAP controller may latch into an unknown state.
