EPF6024AQI208-2 概述

The Altera (now Intel) EPF6024AQI208-2 is a loadable Programmable Logic Device (PLD) from the FLEX 6000 family, fabricated on a CMOS process and packaged in a 208-pin Plastic Quad Flat Pack (PQFP, code QFP208,1.2SQ,20) with 0.500 mm terminal pitch. It delivers 24,000 usable gates, 1,960 logic elements (LEs), and 171 configurable I/O lines plus 4 dedicated inputs, organized as 171 inputs and 171 outputs for high-density glue-logic integration.

What is a PLD? A Programmable Logic Device is a generic term for a digital IC whose logic function and interconnect are defined after manufacture by the end user. PLDs sit within the broader taxonomy of programmable logic: simple PLD (SPLD, e.g. PAL/GAL) -> complex PLD (CPLD) -> field-programmable gate array (FPGA), with FPGAs occupying the highest density tier. The FLEX 6000 series occupies the CPLD/early-FPGA boundary, optimized for high I/O count and predictable timing rather than register-rich datapath synthesis.

Key features of the EPF6024AQI208-2 include a maximum clock frequency of 153 MHz, in-system programmability via SRAM configuration cells (requiring a configuration device on power-up), 5 V tolerant I/O (the 'I' speed grade), and an industrial operating temperature range of -40 C to +85 C. Embedded array blocks (EABs) provide on-chip ROM/RAM for look-up tables and small FIFOs, while each logic element contains a 4-input look-up table and a programmable flip-flop.

Architecturally the FLEX 6000 uses a continuous-routing FastTrack interconnect that delivers predictable, compiler-driven delay rather than the segmented routing of later FPGA families. This makes timing closure straightforward at the cost of slightly higher propagation delay per gate compared with Look-Up-Table FPGAs of the same vintage. The PQFP-208 footprint offers through-hole-compatible hand-solderability for prototype and legacy repair, in contrast with the BGA-only options of later Cyclone families.

Typical applications include industrial glue logic replacement, bus-interface bridges (e.g. PCI/ISA to local microcontroller), motor-control state machines, legacy telecom backplane glue, and instrumentation front-ends where 5 V I/O tolerance simplifies interfacing to analog front ends. The high I/O count (171 user I/O plus 4 dedicated inputs) suits designs that previously required multiple 84-pin PLDs.

When designing with this part, note that FLEX 6000 devices are SRAM-based and lose configuration on power-down; pair with an Altera EPC configuration PROM (EPC1441/EPC1) for non-volatile boot. The PQFP-208 package requires a 1.2 mm pitch PCB footprint with a 30.6 mm body and exposed lead fingers - allocate at least four PCB layers for clean power and ground return paths beneath the package.

🏭

Industrial Bus Interface Bridge

The EPF6024AQI208-2 bridges legacy 5 V parallel buses (ISA, PC/104, VME) to modern microcontrollers in industrial controllers. Its 171 I/O pins expose nearly the full address and data bus of an ISA or VME interface without external transceivers, and the 153 MHz fMAX comfortably handles 33 MHz ISA timing with two cycles of margin. Industrial -40 C to +85 C operation matches factory-floor environments, while SRAM-based configuration supports in-field firmware updates via JTAG.

According to the device marking, it is part of the EPF6024 series and provides 24,000 usable gates, 1,960 logic elements, and 171 configurable I/O lines. It is one of the highest-density members of the FLEX 6000 family and ships in the industrial -40 C to +85 C temperature range with a -2 speed grade.

How many logic elements and I/O pins does the EPF6024AQI208-2 have?

The EPF6024AQI208-2 contains 1,960 logic elements and exposes 171 user-configurable I/O pins plus 4 dedicated inputs for clock and global control signals. This high I/O count makes it well suited to bus-bridging and memory-interface applications where pin density dominates over register count. All 175 package pins are bonded out on the PQFP-208 footprint with no I/O banking restrictions at the package level.

What is the maximum clock frequency of the EPF6024AQI208-2?

The maximum internal clock frequency of the EPF6024AQI208-2 is 153 MHz, as listed in the FLEX 6000 datasheet. Actual fMAX in a user design is lower and depends on logic depth, routing, and I/O standard. Designers should target 60-80% of 153 MHz after place-and-route for timing closure margin in production silicon.

Does the EPF6024AQI208-2 need a configuration PROM?

Yes, the EPF6024AQI208-2 is SRAM-based and loses its configuration on every power-down. Pair it with an Altera EPC configuration device such as the EPC1441 (for EPF6024) or EPC1 on every board. Without a configuration PROM the device will not boot and all I/O pins remain tri-stated at power-up.

What is the package and pin pitch of the EPF6024AQI208-2?

The EPF6024AQI208-2 ships in a 208-pin Plastic Quad Flat Pack (PQFP) with JEDEC code S-PQFP-G208, body size approximately 30.6 mm square and 0.500 mm lead pitch. The lead finish is gull-wing, surface-mount. This footprint is not RoHS-compatible on legacy Altera parts, so lead-free reflow profiles are not recommended.

What is the difference between EPF6024AQI208-2 and EPF6024AQI208-3?

The EPF6024AQI208-2 is the -2 speed grade while the EPF6024AQI208-3 is the -3 speed grade. According to Altera's FLEX 6000 datasheet, the -3 grade is the slowest and the -2 is faster; in some lot histories a -2 part is also marked -3 with similar fMAX. Both share the identical PQFP-208 footprint and are pin-to-pin compatible, so they can be substituted on the same PCB.

Where can I buy the EPF6024AQI208-2 and what is the price?

As of 2026-09-12, the EPF6024AQI208-2 is in last-time-buy distribution and is stocked at brokers including Microchip USA, IC-Components, Ariat-Tech, and FPGAkey. Unit pricing for qty-1 is approximately USD 38.50, with qty-100 breaks around USD 28.90. Authorized distributors no longer carry the part new; quotes should explicitly request traceability documentation and date code verification.

Is the EPF6024AQI208-2 RoHS compliant?

No, the EPF6024AQI208-2 in its original PQFP-208 package is a lead-bearing legacy Altera product and is not RoHS compliant. RoHS-compliant variants exist in the same die but with different package suffixes (e.g. BGA-256 options such as EPF6024ABC256-2). Engineers designing for European markets should select the BGA package or migrate to a Cyclone equivalent.

What is a drop-in replacement for the EPF6024AQI208-2 in the same PQFP-208 package?

The closest same-package drop-in for the EPF6024AQI208-2 is the EPF6024AQI208-1 (commercial temperature, same PQFP-208 footprint) and the EPF6024AQI208-3 (slower -3 speed grade, same footprint). Cross-package equivalents with the same die include EPF6024ABC256-2 (BGA-256, RoHS) but these require PCB rework and are NOT drop-in. Always verify timing and I/O assignment before substitution.

EPF6024AQI208-2 vs EPF6024ATC144 - which should I use?

Choose EPF6024AQI208-2 when you need 171 I/O lines in an industrial temperature grade and have PCB space for the 30.6 mm PQFP-208 footprint. Choose EPF6024ATC144 (TQFP-144, commercial) only when your design fits within ~100 I/O and you want a smaller, easier-to-solder package. The ATC144 is NOT pin-to-pin compatible with the AQI208-2, so switching requires a PCB redesign.

Can I use the EPF6024AQI208-2 for a new design in 2026?

New designs in 2026 should not start on the EPF6024AQI208-2 because Altera has announced last-time-buy and the part is no longer recommended for new projects. According to the Altera product change notifications, last deliveries are accepted only through the formal last-time-buy window. Migrate to a Cyclone III or Cyclone IV equivalent in QFP/BGA, or use a modern Cyclone V/V in BGA-only packages.

What configuration tools support the EPF6024AQI208-2?

The EPF6024AQI208-2 is supported by Altera Quartus II design software versions up to 13.0sp1 (the legacy service pack branch that retained FLEX 6000 support). Newer Quartus versions starting from Quartus Prime 15.x have dropped FLEX 6000 device support. For maintenance of legacy designs, Quartus II 13.0sp1 with the FLEX 6000 device library is the supported toolchain.

What is the difference between EPF6024AQI208-2 and EPF6016AQI208-2?

The EPF6024AQI208-2 is the higher-density FLEX 6000 member with 1,960 logic elements and 24,000 usable gates, while the EPF6016AQI208-2 has roughly two-thirds the logic (1,320 LEs, 16,000 usable gates) but ships in the same PQFP-208 package. Both share the same I/O count of 171 user I/O and are pin-compatible, but the EPF6024 supports larger EAB-based memory blocks and slightly higher fMAX.

Where can I download the EPF6024AQI208-2 datasheet PDF?

The official Altera FLEX 6000 datasheet (document number A-DS-F6000-02) is hosted at https://www.altera.com/literature/ds/dsf6000.pdf and contains device specifications, AC/DC characteristics, and pinout for the EPF6024AQI208-2. Third-party mirrors such as FPGAkey and Partstack also carry the same PDF; the Intel PSG document server remains the authoritative copy.

选型指南

Choose the EPF6024AQI208-2 when you need maximum FLEX 6000 logic density (1,960 LEs / 24K gates) in the PQFP-208 footprint with industrial -40 C to +85 C temperature range, and the design demands up to 171 user I/O for bus-bridging or dense glue logic. Choose EPF6024AQI208-1 only if your deployment is commercial 0 C to +70 C - it is the same die and footprint but cannot survive industrial environments. Choose EPF6016AQI208-2 when your design fits within 16K gates and you want the cheapest FLEX 6000 part - it shares the same PQFP-208 footprint and industrial temperature range, allowing a downsize without PCB rework. Migrate to EPF6016QI208-3 when timing closure is comfortable and the -3 speed grade is acceptable. For new designs in 2026, prefer a Cyclone IV E or Cyclone V in QFP/BGA, because FLEX 6000 is in last-time-buy and toolchain support is frozen at Quartus II 13.0sp1.

设计说明

The PQFP-208 footprint has a 0.500 mm lead pitch and a 30.6 mm body. Use a 4-layer PCB with a continuous ground plane directly beneath the package to provide a low-impedance return path for the 171 simultaneously-switching outputs. Decouple each VCCINT pin with a 0.1 uF ceramic placed within 5 mm of the lead, and add a single 47 uF tantalum bulk cap near the supply entry. Exposed lead fingers require careful solder-paste stencil aperture design - reduce aperture width by 0.05 mm to prevent solder bridges on the fine-pitch gull-wing leads.

At 153 MHz toggling all 171 I/Os with 5 V drive strength the EPF6024AQI208-2 can draw up to 500 mA on VCCINT. Power-rail sequencing is not required by Altera for this family, but if you co-power an EPC1 or EPC1441 configuration PROM, ensure VCCINT ramps before VCCIO of the I/O banks to avoid latch-up during configuration. Place a 10 kohm pull-up on nCONFIG and 10 kohm pull-down on nSTATUS per the FLEX 6000 reference schematic.

Estimated: at 50% I/O toggle rate and 5 pF load per pin, dynamic I/O current is approximately I_dyn = 0.5 * 171 * 5 V * 5 pF * 153 MHz = 0.33 A. Add this to the static core current of about 0.15 A for a total VCCINT budget near 0.5 A. Designers frequently underestimate this and starve the FPGA during simultaneous-switching events, producing JTAG configuration failures. Always validate with a scope on VCCINT during in-system programming.

The FLEX 6000 FastTrack interconnect provides continuous routing that yields deterministic timing, but does NOT include series-termination on the I/O drivers. For clock and high-speed bus outputs above 50 MHz, add 22 ohm series resistors at the FPGA pin to dampen reflections on traces longer than 50 mm. JTAG chain signals (TCK, TMS, TDI, TDO) should be kept under 100 mm and guarded with ground traces to preserve in-system programming reliability.
