EPF6024AQC240-4N 概述
An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that lets designers configure digital logic through a four-step flow (design entry, place-and-route, simulation, programming) without fabricating a custom ASIC. FPGAs occupy the tier between small SPLDs/CPLDs and full ASIC mask sets in the digital design hierarchy: programmable logic -> PLD -> CPLD -> FPGA -> ASIC. The FLEX 6000 series sits at the low-density end of the FPGA taxonomy, intended as a low-cost alternative to gate arrays in glue logic, bus interface, and state-machine applications.
Key features of the EPF6024AQC240-4N include 1,960 logic elements (LEs) and 199 user I/Os, supplied by a 3.3 V core supply with 5 V-tolerant I/O. The device is configured via the IEEE 1149.1 (JTAG) boundary-scan port or the Altera passive serial/parallel configuration scheme, and it stores configuration in a serial configuration EEPROM. The device also supports in-system reprogrammability, allowing design changes without removing the part from the board.
The FLEX 6000 architecture implements each LE as a 4-input LUT plus a programmable register, with FastTrack continuous routing interconnect and MegaLAB structures grouping 16 LEs together. The I/O structure supports per-pin enable, slew-rate control, and PCI-compliant drive. With the -4 speed grade, the EPF6024AQC240-4N delivers the highest toggle performance of the family, with internal frequency targets up to 172 MHz.
Typical applications include bus-interface bridges (e.g., ISA-to-PCI glue), peripheral controllers, custom state machines, and low-cost prototyping of what would later become a mask-programmed gate array. The 240-pin PQFP package is easy to hand-solder and rework, which suits prototype and low-volume production runs.
When designing with this device, ensure configuration storage is sized for the bitstream (configuration memory requirement depends on the design). A JTAG chain is recommended for boundary-scan testability and in-system reconfiguration. Note that the FLEX 6000 family is a legacy part and is no longer recommended for new designs; consider Cyclone or MAX series for new projects.

典型应用
EPF6024AQC240-4N 适用于 6 应用s: ISA-to-PCI Bus Bridge, Custom Peripheral Controller, State Machine Engine, ASIC Prototype / Gate Array Emulation, Legacy Embedded System Glue Logic, JTAG-Based Boundary-Scan Test Platform.
ISA-to-PCI Bus Bridge
The EPF6024AQC240-4N's 1,960 logic elements and 199 user I/Os make it a natural fit for ISA-to-PCI bus bridges in legacy industrial PCs and embedded motherboards. With the -4 speed grade's internal frequency of ~172 MHz, the device can keep up with 33 MHz PCI transactions while emulating ISA cycle timing. The 240-pin PQFP package provides ample I/O to break out both 16-bit ISA (address + data + control) and 32-bit PCI (AD[31:0], C/BE[3:0], FRAME, IRDY, TRDY, DEVSEL) buses simultaneously without external multiplexing. This is a typical glue-logic role where the FLEX 6000 family was originally targeted, replacing custom gate arrays at lower NRE cost.
推荐
Custom Peripheral Controller
The EPF6024AQC240-4N's 196 LABs and fast -4 speed grade suit custom peripheral controllers (such as industrial I/O expansion cards, parallel-port emulators, and bespoke printer controllers) where the BOM must be flexible but the volume does not justify a mask-programmed gate array. The 199 user I/Os at 5 V tolerance simplify interfacing to legacy TTL peripherals without external buffers. Configuration via JTAG enables in-system firmware upgrades in the field, important for industrial controller longevity. Note that new designs should target Cyclone IV instead of the obsolete FLEX 6000 family.
推荐
State Machine Engine
With 1,960 LUT-based logic elements and the FastTrack continuous routing architecture, the EPF6024AQC240-4N is well suited to implementing large FSMs and protocol state machines such as UART, SPI, I2C, HDLC, or proprietary serial protocols. The -4 speed grade delivers the lowest propagation delay in the FLEX 6000 family, ensuring the state machine can meet tight bit-period timing at high baud rates. The 199 user I/Os allow multiple channels to be aggregated without external muxing, and the JTAG port enables on-the-fly state-machine redefinition during bring-up.
推荐
ASIC Prototype / Gate Array Emulation
The EPF6024AQC240-4N was explicitly designed by Altera as a low-cost programmable alternative to mask-programmed gate arrays in prototyping and low-volume production. With 24,000 typical gates, designers can map their intended ASIC netlist into the FLEX 6000 LUT fabric, validate timing in real silicon, and iterate by re-programming until the design stabilizes - then commit to a gate-array mask set. The PQFP-240 package mirrors the pin-count of many mid-density QFP gate arrays of the era, easing pin-compatibility testing.
推荐
Legacy Embedded System Glue Logic
The EPF6024AQC240-4N's PQFP-240 footprint and 5 V tolerant I/Os suit legacy embedded systems (industrial controllers, point-of-sale terminals, medical instruments, military avionics) where a custom glue-logic FPGA has been qualified for decades. The 3.3 V core plus 5 V tolerant I/O allows direct connection to TTL/CMOS peripherals without level shifters, simplifying board layout. Designers maintaining long-lifecycle products can rely on the FLEX 6000 family until the part is replaced by a Cyclone IV migration.
推荐
JTAG-Based Boundary-Scan Test Platform
The EPF6024AQC240-4N's full IEEE 1149.1 JTAG support makes it useful as a boundary-scan and in-system configurability node on legacy boards. The dedicated TCK, TMS, TDI, TDO pins allow it to act as either a master or slave in the JTAG chain, simplifying board-level interconnect test. Combined with its 199 user I/Os, the device can drive enough signals to serve as a generic boundary-scan controller for medium-complexity boards.

设计说明
The EPF6024AQC240-4N requires a clean 3.3 V core supply (VCCINT) plus a separate 3.3 V I/O supply (VCCIO), both at 5 V tolerance on the I/O side. Decouple each VCCINT/VCCIO pin with a 0.1 uF ceramic capacitor placed as close as possible to the package, and add bulk 10 uF tantalum or polymer capacitors near the device. The FLEX 6000 family is sensitive to supply noise during configuration; an unstable VCCINT will cause configuration failures.
The FLEX 6000 family is obsolete and at the end of its lifecycle. Plan a last-time-buy or migrate to a Cyclone IV EP4CE6/EP4CE10 FPGA for any new design. Note that the bitstream format is NOT compatible between FLEX 6000 and Cyclone families - design recompilation in Quartus is mandatory when migrating. Configuration EEPROMs (such as EPC2 or EPC4) used for FLEX 6000 are also obsolete.
The PQFP-240 package has 0.5 mm lead pitch with gull-wing leads - follow standard JEDEC MS-026 land-pattern recommendations. Route all 199 user I/O signals on the top layer where possible to keep stub lengths short. Add a continuous ground plane on the inner layer directly beneath the device for return-path integrity. Leave the JTAG chain accessible via a 4-pin header (TCK, TMS, TDI, TDO) to enable in-system reconfiguration.
Estimated: at maximum toggle activity (~80% of LEs switching at 100 MHz), the FLEX 6000 EPF6024A can dissipate up to ~1.5 W. With the PQFP-240 package's theta_JA of approximately 25 C/W (typical JEDEC test board), junction temperature rises about 38 C above ambient - well within the 0C to +70C commercial range. For sealed enclosures with no airflow, derate clock frequency or reduce utilization to keep Tj below 85 C.
