EPF6024ATC441-1 Présentation
A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be electrically configured by the customer after manufacture to implement arbitrary digital logic. Architecturally, FPGAs belong to the broader hierarchy of programmable logic devices (PLDs), which itself falls under the umbrella of digital logic ICs and finally semiconductors. The FLEX 6000 family in particular uses a fine-grained Look-Up Table (LUT)-based architecture, embedded SRAM blocks, and a continuous FastTrack interconnect fabric, distinguishing it from older macro-cell-based CPLDs. This family represented Altera's mid-density, low-cost, SRAM-programmable logic line in the late 1990s and early 2000s.
Key features of the EPF6024ATC441-1 include its 441-pin plastic QFP package (suffix "C441"), industrial temperature grade (-40C to +85C, denoted by the "I" would be missing here — this part is "A" commercial), 5V-tolerant I/O via multi-voltage interface, in-system programmability through the JTAG-compliant IEEE Std 1149.1 boundary-scan interface, and configurable memory blocks for FIFO and dual-port RAM applications. The device supports the Quartus II design environment (legacy) for synthesis, place-and-route, and timing analysis.
Typical applications include peripheral bus bridges (PCI, ISA, VME), interface translation between microprocessors and peripherals, custom state machines, and protocol conversion glue logic. Designers often selected the FLEX 6000 family when they needed higher density than a CPLD but lower cost and power than contemporary FLEX 10K or APEX families.
When designing with this legacy Altera part, verify last-time-buy and obsolescence status through Altera/Intel PSG, plan for the legacy Quartus II toolchain, and validate pin-out against the official package drawing. Long-term supply chain planning should consider that FLEX 6000 devices are mature nodes with diminishing authorized-stock availability.

Applications typiques
EPF6024ATC441-1 convient pour 6 applications: PCI Bus Interface Bridge, ISA-to-PCI Bridge / Industrial Glue Logic, Custom Peripheral Controller (Microprocessor Glue), Communications Protocol Converter, Digital Signal Processing Front-End (Legacy), Legacy Test & Measurement Equipment.
PCI Bus Interface Bridge
The EPF6024ATC441-1's 24K gates and large QFP-441 I/O make it well-suited to PCI 2.1 bus interface bridging between a microprocessor local bus and peripheral devices. With 3.3V core and 5V-tolerant multi-voltage I/O, the part interfaces directly to legacy 5V PCI peripherals without external level shifters. The FLEX 6000 architecture provides registered I/O cells with individually controllable slew rate and pull-up resistors needed for PCI signal integrity at 33 MHz. Place-and-route in the Quartus II toolchain is mature for PCI reference designs. Estimated: PCI 32-bit/33 MHz implementation typically consumes 60-70% of available logic and ~40% of available I/O, fitting comfortably within EPF6024A capacity.
Recommandé
ISA-to-PCI Bridge / Industrial Glue Logic
Industrial PC backplanes frequently require bus translation between legacy ISA peripherals and modern PCI hosts, and the EPF6024ATC441-1 was a workhorse for this role in the early 2000s. The 441-pin QFP exposes enough I/O for full 16-bit ISA data + 24-bit address plus 32-bit PCI bus, all in a single device. Multi-voltage I/O (3.3V core, 5V tolerant) lets one part interface both bus voltages without external translation. JTAG boundary-scan (IEEE 1149.1) gives manufacturing test access for bed-of-nails replacement on production lines. Estimated: full ISA-PCI bridge consumes ~18K gates and ~80 I/O pins, well within EPF6024ATC441-1's 24K-gate / ~218-I/O envelope.
Recommandé
Custom Peripheral Controller (Microprocessor Glue)
The EPF6024ATC441-1 commonly served as the 'glue logic' between microprocessors, memory, and peripherals in embedded control designs, replacing dozens of 74-series TTL parts with a single reprogrammable device. With 24K gates and ~218 user I/O, designers implemented address decoding, wait-state generation, DMA controllers, and interrupt controllers in one chip. SRAM-based configuration allowed in-field firmware updates via JTAG without re-spinning the PCB. The QFP-441 footprint gave ample I/O for ISA-style microprocessor buses (Motorola 68000, Intel x86). Estimated: a full 68000 glue-logic design consumes ~12-15K gates, leaving headroom for application-specific state machines in the same device.
Recommandé
Communications Protocol Converter
Protocol converters between industrial serial buses (RS-232, RS-422, RS-485, HDLC) and parallel microprocessor interfaces were a typical FLEX 6000 application, leveraging the architecture's register-rich design and fast I/O. The EPF6024ATC441-1's multi-voltage I/O lets it directly interface both 3.3V microprocessors and 5V transceivers, eliminating external level shifters. Embedded SRAM blocks (EABs) implemented small FIFOs for UART buffering, while logic elements handled protocol state machines. The QFP-441's high I/O count supports multi-channel designs (e.g., 4-channel UART bridge). Estimated: a 4-channel UART bridge consumes ~14K gates and ~40 I/O, easily fitting within EPF6024ATC441-1's capacity.
Recommandé
Digital Signal Processing Front-End (Legacy)
While not a DSP-optimized FPGA, the EPF6024ATC441-1 was occasionally used in low-bandwidth digital signal processing front-ends such as FIR filter banks, data-acquisition pre-processing, and simple video timing generation. Its 24K gates accommodate modest FIR filters (16-tap, 8-bit), and embedded SRAM blocks implement coefficient tables and delay lines. Multi-voltage I/O supports direct connection to 5V ADC/DAC devices common in legacy data-acquisition systems. The QFP-441 I/O budget easily handles parallel ADC bus interfaces. Estimated: a 16-tap 8-bit FIR filter consumes ~6K gates, leaving ~18K gates for control logic and interfaces in the same device.
Recommandé
Legacy Test & Measurement Equipment
Test-and-measurement equipment manufacturers adopted the FLEX 6000 family for custom waveform generators, timing analyzers, and protocol exercisers where discrete logic was impractical. The EPF6024ATC441-1's large I/O count and SRAM-based programmability enabled design reuse across product variants by simply swapping configuration bitstreams. JTAG boundary-scan (IEEE 1149.1) provided manufacturing test coverage for fine-pitch QFP packages that bed-of-nails fixtures cannot easily probe. The QFP-441's high I/O count handled parallel instrument buses and front-panel connector interfaces. Estimated: a typical instrument front-end design consumes 15-20K gates, fitting within EPF6024ATC441-1's 24K-gate capacity with margin for revision changes.

- Multi-voltage I/O eliminates external level shifters (vs EPF6010ATC144-1 (smaller FLEX 6000 family member))
Notes de conception
The EPF6024ATC441-1 requires a clean 3.3V core supply (VCCINT) with decoupling of at least 0.1uF ceramic + 10uF bulk per power pin. Estimated: at typical 50% toggle rate, core current draw is 80-150 mA. Multi-voltage I/O banks require separate VCCIO rails (3.3V or 5.0V). Use a ferrite bead or pi-filter between the 5V analog supply and VCCIO if 5V tolerance is used to prevent supply noise coupling into I/O logic. Estimated total power consumption at full I/O utilization is 0.5-1.0 W.
The QFP-441 package has 0.5 mm lead pitch and 28x28 mm body, demanding 4-layer PCB with controlled-impedance traces for clock and JTAG signals. Estimated: escape routing requires 4-6 PCB layers with microvia fanout. Add a 0.1uF decoupling cap within 5 mm of every power pin (VCCINT and VCCIO). Exposed thermal pad (if present on QFP variant) should be soldered to a copper pour with thermal vias to dissipate ~0.5-1.0 W. JTAG chain signals (TCK/TMS/TDI/TDO) require matched-length routing to avoid boundary-scan issues.
Do not assume EPF6024ATC441-1 has active pull-ups on all I/O pins - configure them in the Quartus II software per pin. The DEV_OE and DEV_CLR pins are active-low global signals that must be pulled high during normal operation; floating these pins will put the device in test mode. nCONFIG requires a clean rising edge for configuration start - any glitches trigger reconfiguration. When migrating from JTAG configuration to passive serial configuration, ensure the configuration memory size matches the bitstream file (typically 1 Mbit for EPF6024A).
The commercial-grade EPF6024ATC441-1 (0C to +70C) is not suitable for industrial applications. For industrial temperature (-40C to +85C), use the EPF6024AQI-series variants (Site MPN list: EPF6024AQI240-3N, EPF6024AQI208-2N, etc.). Estimated thermal resistance (theta_JA) for QFP-441 is approximately 20-25 C/W with 4-layer PCB and standard copper pour - allowing ~3-4 W dissipation without airflow at 70C ambient.
