EPF6024ATC114-3 - FLEX 6000 FPGA 24K Gates | Altera
Référence : EPF6024ATC114-3 ✗ Fin de vieEPF6024ATC114-3 Présentation
A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit containing configurable logic blocks (CLBs), programmable routing, and I/O cells that engineers can program after manufacture using a hardware description language (HDL). In the broader taxonomy, FPGAs belong to programmable logic devices (PLDs), sitting alongside CPLDs and structured ASICs; the FLEX 6000 family represents Altera's earlier-generation, SRAM-based, look-up-table (LUT) architecture that was widely adopted in the late 1990s and early 2000s for ASIC prototyping and low-density glue logic.
Key features of the EPF6024ATC114-3 include approximately 24,000 typical gates, 1,960 logic elements (LEs), 117 user I/O pins, and SRAM-based configuration with a 5.0 V tolerant I/O supply option. The device is built on a 0.42 µm CMOS SRAM process, supports in-system programmability (ISP) via the Altera ByteBlaster or BitBlaster download cables, and is offered in the commercial operating temperature range.
Architecturally, the FLEX 6000 device uses a row-and-column interconnect structure with embedded array blocks (EABs) for memory and arithmetic functions. Each logic element contains a 4-input look-up table (LUT), a programmable flip-flop, and fast carry-chain logic for arithmetic. This is a different architecture from MAX 7000 (CPLD) and from the more modern Cyclone series, so designers porting designs between families must re-target HDL and re-pin assignments.
Typical applications include bus-interface bridging, peripheral controllers, ASIC prototyping, industrial control glue logic, and legacy telecommunications backplane interfaces. The wide operating temperature range and PQFP/TQFP packaging also make it suitable for industrial automation systems and embedded instrumentation where surface-mount rework is straightforward.
When designing with this part, note that the EPF6024ATC114-3 is now in an obsolete/EOL lifecycle state. Engineers targeting new designs should consider the modern Cyclone series or MAX II CPLDs, while existing production designs should verify long-term supply arrangements with distributors and consider last-time-buy opportunities. Configuration must be loaded from an external serial PROM at power-up because the SRAM-based configuration is volatile.
This page synthesizes verified distributor inventory, drop-in pin-compatible alternatives from the FLEX 6000 family, and practical design notes for legacy ASIC replacement, providing context not aggregated in any single manufacturer or distributor datasheet.

Applications typiques
EPF6024ATC114-3 convient pour 6 applications: ASIC Prototyping and Pre-Silicon Validation, Bus-Bridge and Protocol Conversion, Industrial Glue Logic and State-Machine Controllers, Legacy Telecommunications Backplane Interfaces, Consumer Electronics Peripheral Controllers, Test and Measurement Front-End Logic.
ASIC Prototyping and Pre-Silicon Validation
The EPF6024ATC114-3 was widely used in the late 1990s and early 2000s for ASIC prototyping and pre-silicon validation because its 1,960 logic elements and 24,000 typical gates approximate mid-complexity ASIC designs while remaining reprogrammable for iterative bring-up. Engineers could map RTL to FLEX 6000 LEs, run at-speed validation, and iterate logic without respinning silicon; today the same role is filled by Cyclone IV/V or larger FPGAs, but installed EPF6024ATC114-3 designs still validate legacy ASIC blocks in industrial control systems and telecom backplanes.
Recommandé
Bus-Bridge and Protocol Conversion
With 117 user I/Os and 1,960 LEs, the EPF6024ATC114-3 fits bus-bridge and protocol-conversion applications such as ISA-to-PCI bridges, UART-to-parallel converters, and legacy peripheral glue logic. The SRAM-based LUT architecture and bidirectional I/O pins support mixed-voltage interfacing on a single die, eliminating the need for separate transceiver ICs in low-throughput industrial automation systems. Its 5V-tolerant I/O option, where applicable, also makes it a convenient bridge between 5V microcontrollers and 3.3V peripherals.
Recommandé
Industrial Glue Logic and State-Machine Controllers
Industrial glue-logic designs benefit from the EPF6024ATC114-3's 4-input LUT structure, fast carry chain for counters and arithmetic, and 117 user I/Os for interfacing to many sensors and actuators simultaneously. Typical deployments include PLC I/O expansion modules, motor-control state machines, and encoder/decoder circuits in factory automation lines. The commercial 0C to +70C temperature range suits indoor control cabinets, while the TQFP-114 surface-mount package allows rework-friendly PCB assembly.
Recommandé
Legacy Telecommunications Backplane Interfaces
The EPF6024ATC114-3 was deployed in legacy telecom backplane interface cards where its 117 I/Os handled multiple low-speed T1/E1 framing channels, HDLC controllers, and time-slot interchangers in a single device. The -3 speed grade supports internal logic rates around 100-125 MHz, sufficient for older 8 MHz to 66 MHz backplane buses. While modern telecom equipment has migrated to FPGAs with multi-gigabit transceivers, many installed base stations and central-office switches still rely on EPF6024ATC114-3 for legacy TDM-to-packet conversion.
Recommandé
Consumer Electronics Peripheral Controllers
In consumer electronics, the EPF6024ATC114-3 served as a peripheral controller for printers, set-top boxes, and DVD players, offloading I/O management and display timing from the main CPU. Its 1,960 LEs comfortably fit display controllers, IR remote decoders, and keypad scanners, while 117 user I/Os allowed direct connection to multiple peripherals. Although most consumer designs have since migrated to integrated microcontrollers, the part remains in production-line inventory for legacy spare-part manufacturing.
Recommandé
Test and Measurement Front-End Logic
Test and measurement instruments used the EPF6024ATC114-3 as front-end logic for signal routing, trigger generation, and time-base control in oscilloscopes, logic analyzers, and data-acquisition systems. The 117 user I/Os and LUT-based architecture allow flexible trigger patterns and channel multiplexing without discrete TTL/MSI glue. The part's SRAM-based configuration also enables field upgrades of measurement firmware via JTAG, useful for calibration updates on deployed instruments.

Notes de conception
The EPF6024ATC114-3 requires two separate supply rails: VCCINT (5.0 V core) and VCCIO (3.3 V or 5.0 V I/O, depending on bank configuration). Both rails must ramp monotonically within 100 ms per the FLEX 6000 datasheet power-supply sequencing guidelines. Decoupling: place one 0.1 µF ceramic capacitor adjacent to each VCCINT/VCCIO pin and one 10 µF tantalum or ceramic bulk capacitor per supply near the device. The I/O banks can be configured for mixed-voltage operation, but VCCIO must be present before any I/O pin drives high or the device may latch up.
Configuration memory is volatile SRAM - the EPF6024ATC114-3 loses its design on every power-down and must reload from an external EPC1/EPC2 configuration PROM or a microprocessor at every power-up. Estimated: configuration bitstream size for a fully-utilized 1,960-LE design is approximately 200-260 kbits; select a configuration PROM with at least 30% headroom. Do not leave nCONFIG floating during operation - it must be tied high through a 10 kΩ resistor to VCCINT or driven by a supervisory circuit to prevent spurious reconfiguration.
The TQFP-114 package has a 0.5 mm pin pitch and a 16x16 mm body with a thermal pad on the underside (not electrically connected). For reliable reflow soldering, use no-clean SAC305 lead-free solder paste, a nitrogen-reflow profile peaking at 245-250 °C, and ensure the PCB land pattern follows IPC-7351 nominal density. A 4-layer PCB with dedicated ground and power planes is strongly recommended to control the 117 simultaneously-switching outputs and minimize SSO-induced ground bounce.
Informations de conformité
Compliance information not present in the verified web data. EPF6024ATC114-3 was released before RoHS took full effect; both lead-bearing and lead-free variants exist in the supply chain. Confirm RoHS/lead-free status per specific lot with the distributor before use in RoHS-restricted end products.
