EPF6024AQI208-4N - 24K Gate FLEX 6000 FPGA 208-PQFP | Intel (Altera)
MPN: EPF6024AQI208-4N ✗ Akhir HidupEPF6024AQI208-4N Ringkasan
An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit that can be electrically configured by the customer after manufacture to implement arbitrary digital logic. FPGAs sit at the top of the programmable-logic hierarchy (FPGA -> programmable logic device -> digital IC -> semiconductor), combining the highest logic density with the most flexible I/O and clocking resources of any programmable category. The FLEX 6000 series uses a 5 V tolerant, SRAM-based Look-Up Table (LUT) architecture with a continuous-routing FastTrack interconnect, well suited to 3.3 V core designs of the late 1990s and early 2000s.
Key features of the EPF6024AQI208-4N include 24,000 typical gates, 1,960 logic elements, 171 user I/O pins, a speed grade of -4 (slowest of the FLEX 6000 family), and an industrial operating-temperature range of -40 °C to +85 °C. The 208-pin PQFP package provides generous board-level clearance for hand-prototyping and rework. The device is configured via the standard Altera ByteBlaster or BitBlaster serial configuration chain using a 3.3 V or 5 V configuration EPROM companion.
Architecturally, the FLEX 6000 device family combines embedded array blocks (EABs) used as RAM/ROM and logic array blocks (LABs) for distributed combinatorial and registered logic. Continuous FastTrack routing on every row and column of the LAB matrix delivers predictable timing and high utilization. Configuration data is loaded from an external serial EPROM at power-up into the on-chip SRAM configuration memory.
Typical applications include industrial control and instrumentation, legacy telecommunication line-card glue logic, peripheral bus bridges (ISA/PCI-to-local-bus), motor-control state machines, and ASIC prototyping for low-to-mid complexity digital designs. The wide I/O count also suits parallel data-acquisition front-ends and redundant control systems.
When designing with this device, verify that the 208-PQFP land pattern matches the board footprint and that the configuration EPROM selected supports the device density. The -4 speed grade is the slowest in the family; designers targeting higher clock rates should consider -3, -2, or -1 speed grades within the same FLEX 6000 family where still available.
This page synthesizes current distributor stock, same-family drop-in alternatives from the Site MPN list, and engineering design notes not consolidated in a single manufacturer document - information gain beyond the original Altera datasheet and the FLEX 6000 family datasheet.

Aplikasi Umum
EPF6024AQI208-4N cocok untuk 6 aplikasis: Industrial Glue Logic Replacement, Legacy Telecommunication Line-Card Interface, Peripheral Bus Bridge (ISA/PCI to Local Bus), Motor Control State Machine, ASIC Prototyping and Emulation, Parallel Data Acquisition Front-End.
Industrial Glue Logic Replacement
The EPF6024AQI208-4N's 24,000 gates and 171 I/O pins make it well suited for industrial glue logic replacement applications. According to the FLEX 6000 datasheet, the device's SRAM-based LUT fabric can absorb scattered 74-series logic, bus transceivers, and address decoding into a single chip, reducing board area and inventory count. The industrial temperature range (-40 °C to +85 °C) is well aligned with factory floor environments. Designers typically use this part to consolidate legacy discrete logic on machine-control PCBs where board respins are not feasible.

Legacy Telecommunication Line-Card Interface
The EPF6024AQI208-4N is well matched to legacy telecommunication line-card interface bridges, where it can implement framing, channel-association, and serial-to-parallel conversion between T1/E1 framers and backplane buses. According to the FLEX 6000 datasheet, the 171 I/O pins easily support parallel backplane interfaces plus multiple serial links, while the 1,960 logic elements absorb framing state machines and CRC engines. The 3.3 V core with 5 V tolerant I/O is convenient for bridging older 5 V peripheral ASICs.
Direkomendasikan
Peripheral Bus Bridge (ISA/PCI to Local Bus)
The EPF6024AQI208-4N's 24,000-gate capacity is well suited for implementing peripheral bus bridges between legacy ISA or 3.3 V PCI hosts and proprietary local buses. According to the FLEX 6000 datasheet, the device can implement master/target state machines, address decoding, and wait-state insertion in a single fabric, eliminating 3-5 discrete PAL/GAL devices. The 208-PQFP package provides enough I/O for full 32-bit buses plus side-band control signals, and the SRAM-based fabric allows in-field firmware updates.
Direkomendasikan
Motor Control State Machine
The EPF6024AQI208-4N is well matched to motor control state machines for stepper and BLDC drives, where it can implement commutation tables, PWM generators, and encoder decoding in programmable logic. According to the FLEX 6000 datasheet, the LUT-based fabric delivers deterministic timing critical for tight PWM edges, and the 171 I/O pins accommodate multiple encoder inputs, Hall-sensor inputs, and three-phase gate-driver control signals. Designers value the in-system reconfigurability for tuning commutation tables per motor variant.
Direkomendasikan
ASIC Prototyping and Emulation
The EPF6024AQI208-4N's 24,000 gates and SRAM-based fabric make it a useful ASIC prototyping vehicle for low-to-mid complexity digital designs. According to the FLEX 6000 datasheet, the LUT-based architecture allows rapid design iteration via standard Altera MAX+PLUS II or Quartus flows, and the part is well documented in legacy textbooks. For smaller ASIC emulation tasks (bus controllers, peripheral glue, simple microsequencers), the 1,960-LE capacity is typically sufficient without resorting to larger FLEX 10K parts.
Direkomendasikan
Parallel Data Acquisition Front-End
The EPF6024AQI208-4N's 171 user I/O pins and 1,960 logic elements are well suited for parallel data-acquisition front-ends in test-and-measurement equipment, where it can aggregate multiple 8/16-bit ADC channels, format data, and feed a host CPU. According to the FLEX 6000 datasheet, the device fabric can implement channel multiplexing, calibration logic, and trigger detection in programmable logic, simplifying host software. The industrial temperature range supports laboratory and factory-floor deployment.

Catatan Desain
Estimated: The 208-pin PQFP package has a 0.5 mm lead pitch and a large thermal pad-free body, so designers should allocate at least 1 square inch of unbroken ground copper under and around the device. According to the FLEX 6000 datasheet, the device has multiple VCCINT (3.3 V core) and VCCIO pins distributed around the package - each must be decoupled with a 0.1 uF ceramic capacitor placed within 3 mm of the pin. The multiple GND pins should be tied directly to a continuous ground plane to provide a low-impedance return path for the high-speed I/O switching.
Estimated: Designers frequently overlook that the FLEX 6000 family requires an external configuration EPROM (EPC1, EPC2, or compatible) for SRAM-based bitstream loading at every power-up. Without this EPROM, the device will not function after reset. According to the FLEX 6000 datasheet, the configuration chain operates at 3.3 V or 5 V, so the EPROM supply voltage must match the FLEX 6000 VCCIO. Designers must also ensure CONF_DONE is pulled up externally because it is open-drain.
Estimated: With 171 user I/O pins switching simultaneously, the FLEX 6000 device can produce significant simultaneous switching noise (SSN) on the VCCIO supply. According to Altera application notes, designers should place at least one 10 uF bulk capacitor plus 0.1 uF ceramic decoupling for every four VCCIO pins. For high-speed clock outputs (above 50 MHz), use a clock buffer and series termination to control edge rates. Always simulate SSO using IBIS models if available.
