EPF6024ATC144 - FLEX 6000 FPGA 24K Gates 117 I/O 144-LQFP | Altera
MPN： EPF6024ATC144 ⚠ 最後購買機會EPF6024ATC144 概覽
An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and programmable I/O cells. FPGAs occupy a unique position in the digital logic hierarchy: above fixed-function ASICs and standard-cell logic in flexibility, below microcontrollers in software-defined programmability, and alongside DSPs and CPLDs as the dominant reconfigurable-logic platform. The FLEX 6000 family in particular targets glue-logic, bus-interface, and high-volume gate-array replacement applications.
Key features of the EPF6024ATC144 include the OptiFLEX architecture with 4-input look-up tables (LUTs), built-in registers per logic element for easy pipelining, dedicated carry and cascade chain paths, and 196 LABs (Logic Array Blocks). The device supports in-system programmability via the IEEE 1149.1 JTAG interface and offers MultiVolt I/O for interfacing between 3.3 V and 5.0 V systems. JTAG-based boundary-scan testing is built in for board-level diagnostics.
The architecture delivers up to 166 MHz internal operation with low static and dynamic power consumption. The 117 user I/Os are distributed across the LQFP-144 footprint and support PCI-compatible drivers, 5.0-V input tolerance with proper pull-up configuration, and hot-socketing capability. Configuration memory is SRAM-based, requiring an external configuration device such as the EPC2 or EPC8 for standalone boot.
Typical applications for the EPF6024ATC144 include PCI bus interfaces, peripheral bridge logic in embedded systems, industrial glue logic replacing discrete 74-series TTL, glue logic in telecom line cards, custom interface bridges for legacy peripherals, and pre-production prototyping of ASIC designs. Its high I/O count relative to logic capacity makes it ideal for I/O-heavy glue applications rather than compute-intensive DSP.
When designing with this part, note that SRAM-based FPGAs require a configuration ROM on every board; the EPF6024ATC144 cannot boot standalone. A 100 µF bulk capacitor plus 0.1 µF decoupling per VCC/GND pair is recommended, and unused I/Os should be left floating or driven to a defined state per Quartus configuration directives.

典型應用
EPF6024ATC144 適用於 6 應用s: PCI Bus Interface Bridge, Peripheral Bridge for Legacy Systems, ASIC Pre-Production Prototyping, Industrial Glue Logic Replacement, Telecom Line Card Interface, Motor Control and Drive Interface.
PCI Bus Interface Bridge
The EPF6024ATC144 is well suited for PCI bus bridge and protocol-translation functions in industrial and embedded systems. Its 117 user I/Os provide ample headroom for 32-bit PCI data plus control and arbitration signals at 33 MHz. The device's 3.3 V core with 5.0 V tolerant I/O via pull-up resistors matches PCI's mixed-voltage signaling environment. Engineers typically use 196 LABs to implement target-state machines, address decoding, and interrupt logic. Compared to discrete 74-series glue logic, a single EPF6024ATC144 replaces dozens of packages, reducing board area and BOM cost. The SRAM-based configuration also enables post-production bug fixes via JTAG without respinning the board.
推薦
Peripheral Bridge for Legacy Systems
In long-life industrial and telecom platforms, the EPF6024ATC144 bridges modern microcontrollers to legacy peripherals such as ISA-bus devices, parallel-port interfaces, and 8/16-bit memory-mapped I/O. The OptiFLEX architecture's 4-input LUTs and per-LE registers implement custom address-decoding and bus-multiplexing logic with deterministic timing. The LQFP-144 footprint is friendly to hand-rework and field-repair scenarios common in industrial customer support. Hot-socketing and 5.0 V tolerant inputs ease integration with mixed-voltage backplanes. The bitstream can be updated over JTAG for field firmware upgrades without swapping boards.
推薦
ASIC Pre-Production Prototyping
Engineers use the EPF6024ATC144 to prototype ASIC designs before committing to NRE mask costs. With 24,000 gates and 117 I/Os, it covers a large class of gate-array-replacement designs in telecom, industrial control, and consumer devices. Quartus II software (the legacy Altera toolchain) supports the device for HDL entry, synthesis, place-and-route, and timing closure. Once the design is verified, the same HDL source can be retargeted to a hard ASIC or migrated to a Cyclone FPGA. The LQFP-144 package supports easy rework and even hand-wired prototype boards during early development.
推薦
Industrial Glue Logic Replacement
The EPF6024ATC144 replaces dozens of 74HC/74F-series TTL packages in industrial control and instrumentation designs, drastically reducing board area, power consumption, and assembly cost. Common conversions include address decoders, bus arbiters, custom multiplexers, encoder/decoder pairs, and handshake sequencers. The 5.0 V input tolerance with proper pull-up resistors allows direct replacement of legacy 5.0 V TTL boards. Designers report 5-10x package-count reduction and improved reliability through fewer solder joints. Quartus captures the design once and reuses the bitstream across multiple product variants.
推薦
Telecom Line Card Interface
Telecom line cards use the EPF6024ATC144 to implement proprietary backplane interfaces, framer-to-TDM bus adapters, and timing-recovery glue between network processors and PHY devices. The 117 user I/Os accommodate parallel TDM streams, JTAG, and management interfaces simultaneously. MultiVolt I/O simplifies interfacing between 3.3 V ASICs and 5.0 V legacy framers. Long-term availability through Last Time Buy channels keeps mature line cards in production while redesigns progress. Engineers favor the FLEX 6000 family for its deterministic timing and well-documented Quartus synthesis flow.
推薦
Motor Control and Drive Interface
Industrial motor drives use the EPF6024ATC144 to implement encoder interfaces (Quadrature, SSI, BiSS), PWM generation, current-sense signal conditioning timing, and protection logic between DSPs/MCUs and the power stage. The 117 I/Os handle multiple encoder channels, gate-driver enable signals, and fault inputs in parallel. 5.0 V tolerant inputs interface with legacy Hall-sensor and opto-isolator front-ends. The deterministic register-per-LE architecture supports cycle-accurate timing for PWM edges and dead-time insertion. Compared to a microcontroller, the EPF6024ATC144 offloads time-critical I/O handling, freeing the MCU for higher-level control loops.

主要差異化特點
- Largest FLEX 6000 device in 144-LQFP footprint (對比EPF6016ATC144-1)
- MultiVolt I/O supports legacy 5.0 V systems (對比EPF10K50ETC144-1 (FLEX 10K family))
- Pin-compatible within FLEX 6000 family (對比EPF10K30ETI144-2 (FLEX 10K family))
設計說明
The EPF6024ATC144 requires a clean 3.3 V core supply (VCCINT) and a separate 3.3 V or 5.0 V I/O supply (VCCIO). Place a 100 µF tantalum bulk capacitor at the board input plus one 0.1 µF ceramic decoupling capacitor per VCCINT/VCCIO pin pair to suppress switching transients during configuration and high-I/O activity. Estimated dynamic current draw at 166 MHz across 117 I/Os can reach 200-400 mA; ensure the 3.3 V regulator has at least 1 A headroom.
LQFP-144 has 0.5 mm pitch leads that are hand-rework friendly but require careful PCB layout. Use 4-layer board with continuous ground plane under the device; route JTAG signals (TDI, TDO, TMS, TCK) with 50 Ω controlled impedance and keep them away from high-speed I/O. Place the EPC2/EPC8 configuration ROM within 2 inches of the FPGA data pins to avoid signal-integrity issues during configuration. Unused I/Os should be configured per Quartus directives as input-tristate with internal weak pull-up to prevent floating-input oscillation.
The EPF6024ATC144 uses SRAM-based configuration memory, which is volatile — the device does NOT retain its design on power-down. An external configuration ROM (EPC2, EPC8, or compatible) must be present or the FPGA will fail to boot. Second, the 5.0 V input tolerance on I/O pins requires an external pull-up resistor to a 5.0 V rail — connecting 5.0 V directly without the pull-up will exceed absolute-max ratings. Finally, verify the correct speed grade (-1, -2, -3) is loaded in Quartus before programming; mismatched speed grades can cause timing failures that are difficult to debug.
