EP2A70F1508C7N Overview
An FPGA is a semiconductor containing configurable logic blocks, routing resources, and programmable I/O elements. Unlike a fixed ASIC, an FPGA can be configured after manufacturing and revised in the field. It sits within the broader semiconductor hierarchy as programmable logic, sharing the same general class as CPLDs while providing much higher logic density, embedded memory, and parallel processing capability. APEX II devices combine logic, memory, and interface resources in one programmable fabric.
The headline density of 67,200 cells supports large combinational and sequential designs, while 1,060 programmable I/O pins provide substantial external connectivity. The APEX II family is identified in the verified data as providing 6,720 logic array blocks and 1,146,880 total RAM bits. The device also carries a 3 million-gate family description in the supplied sources. A 1.5 V core and 0.15 µm CMOS process place the component in a mature high-density FPGA family rather than a modern low-power architecture.
The listed 420 MHz figure describes the device's stated capability, but system-level performance depends on placement, routing, configuration, clock resources, I/O standards, and design implementation. The combination of high cell count and high I/O count is useful for designs that require many independent interfaces or wide parallel buses. Designers should use the manufacturer timing documentation and supported software flow for the exact device variant before committing to a clock target.
Typical applications include telecommunications equipment, industrial automation, test and measurement, video or image processing, and communications infrastructure. The large RAM resource suits buffering and packet or sample processing, while the 1,060 I/O pins can support broad sensor, memory, or peripheral interfaces. The 0°C to 85°C temperature range is appropriate for many commercial and industrial environments, but system airflow and junction conditions still require review.
When designing with EP2A70F1508C7N, verify the complete 1508-pin FC-FBGA land pattern, power sequencing, configuration interface, and supported configuration memory. The verified data does not provide the full pin assignment, package dimensions, supply-current limits, or thermal resistance, so those values remain rather than inferred. This page combines verified distributor and manufacturer-source data with practical replacement guidance and explicitly identifies missing technical fields.

Typical Applications
EP2A70F1508C7N is suitable for 6 applications: Legacy Telecommunications Equipment, Industrial Automation Controllers, Test and Measurement Instrumentation, Video and Image Processing, Communications Protocol Bridging, Legacy Embedded Control Systems.
Legacy Telecommunications Equipment
EP2A70F1508C7N is suitable for maintaining legacy telecommunications equipment that already uses an Altera APEX II FPGA and has established bitstreams, board constraints, and timing margins. Its verified 67,200 logic cells, 1,060 programmable I/O pins, and 1,146,880 RAM bits provide substantial resources for interface aggregation, protocol adaptation, packet buffering, and parallel datapaths. The stated 420 MHz capability can support demanding legacy digital functions, although actual timing closure depends on placement, routing, configuration, and the selected I/O standard. The 0°C to 85°C range also supports equipment deployed in controlled commercial and industrial environments. Use the existing firmware and toolchain where possible, preserve the original configuration method, and validate any replacement against the complete 1508-pin ball map. EP2A40F1508 and EP2A70B724I7 are listed as possible Altera-family migration candidates, but neither has verified drop-in equivalence in the supplied data.
Recommended
Industrial Automation Controllers
EP2A70F1508C7N can serve in an established industrial automation controller requiring many deterministic I/O channels and substantial programmable logic. The verified 1,060 programmable I/O pins are useful for connecting motor-control peripherals, sensor interfaces, safety-status signals, communication bridges, and local memory devices. Its 67,200 logic cells and 1,146,880 RAM bits support state machines, real-time data processing, protocol conversion, and buffering without relying entirely on a processor. The 0°C to 85°C operating range covers many controlled industrial environments, but the supplied data does not confirm industrial qualification, so the system qualification process remains mandatory. Confirm power integrity, configuration storage, clock distribution, and thermal margins in the existing controller. A new platform should compare a supported FPGA because EP2A70F1508C7N is obsolete; use EP2A70F1508C7 or EP2A70F1508C7ES only after reviewing suffix-level specifications and board-level equivalence.
Recommended
Test and Measurement Instrumentation
EP2A70F1508C7N fits legacy test and measurement instruments that need parallel acquisition, timing generation, signal conditioning control, and multiple communications interfaces. The device's 67,200 logic cells can implement counters, trigger logic, serializers, control loops, and instrument-state management, while the 1,146,880 RAM bits can buffer samples or intermediate results. The 1,060 programmable I/O pins are especially valuable when an instrument has many front-end channels, control lines, or bus adapters. The stated 420 MHz capability can support fast deterministic processing, but the final design must be timed using the exact Altera device and configuration conditions. Because the part is obsolete, maintenance designs should preserve known-good bitstreams and configuration files while documenting the original pinout and power requirements. A replacement study should compare supported members of the Altera portfolio, including EP2A40F1508 as a possible 1508-package family candidate, without assuming functional equivalence.
Recommended
Video and Image Processing
EP2A70F1508C7N is appropriate for legacy video or image-processing systems that already depend on APEX II logic and require high I/O connectivity. The 67,200 logic cells can implement pixel pipelines, synchronization, format conversion, color-space processing, and frame-control functions, while 1,146,880 RAM bits support line buffers, lookup tables, and intermediate frame storage. The 1,060 programmable I/O pins allow parallel video buses, camera interfaces, memory connections, and control channels to coexist. The 420 MHz stated capability may support high-throughput designs, but video timing, memory bandwidth, I/O electrical standards, and routing congestion determine the achievable result. Validate the design with the exact legacy toolchain and preserve timing constraints from the original implementation. Modern video equipment should generally use a supported FPGA with current transceivers, memory interfaces, and software support. EP2A70F1508C7 is a same-family ordering-code reference, while EP2A40F1508 is a possible 1508-package comparison, not a confirmed drop-in replacement.
Recommended
Communications Protocol Bridging
EP2A70F1508C7N can bridge multiple communications protocols in an existing digital system, including parallel bus adaptation, clock-domain translation, framing, buffering, and error handling. The device's 67,200 logic cells provide capacity for multiple independent protocol engines, and the 1,146,880 RAM bits can buffer packets or transfer data between asynchronous domains. Its 1,060 programmable I/O pins support broad bus and peripheral connectivity, while the stated 420 MHz capability may be useful for high-speed legacy interfaces. The design must define the exact I/O standards, clock constraints, termination, and board signal integrity before implementation. Since the FPGA is obsolete, use the original configuration and pinout as the source of truth for maintenance; migration to a supported Altera device requires reimplementation and possibly a new PCB. EP2A70B724I7 can be evaluated for family-level architectural comparison, but its package and electrical equivalence are not established by the supplied data.
Recommended
Legacy Embedded Control Systems
EP2A70F1508C7N is a practical choice for extending the life of an embedded control platform whose hardware, firmware, and certification evidence are already based on APEX II. The 67,200 logic cells can host control algorithms, interface state machines, diagnostic logic, and peripheral bridges, while 1,146,880 RAM bits support queues, tables, and transient data storage. The 1,060 programmable I/O pins are useful for connecting external memories, sensors, actuators, and management buses. The listed 0°C to 85°C range is relevant to controlled commercial systems, but the supplied data does not establish extended-temperature or automotive qualification. Maintain a controlled stock of the original part where possible, and use EP2A70F1508C7 or EP2A70F1508C7ES only after confirming ordering-code details. For new control-system designs, select a current FPGA and modern development flow rather than introducing a new dependency on an obsolete 1508-pin FC-FBGA component.

Design Notes
EP2A70F1508C7N is listed with a 1.5 V core voltage, but supply current, power-up sequencing, and decoupling requirements are not present in the verified web data. Use the original Altera power-supply reference design as the authoritative source, confirm the exact configuration and I/O activity, and estimate current before selecting regulators. Place local decoupling close to the FC-FBGA supply balls and keep the power-plane return path continuous. Do not infer power consumption from the 420 MHz figure alone.
The verified operating range is 0°C to 85°C, but junction temperature, thermal resistance, and maximum power dissipation are [DATA_NEEDED]. For a legacy board, reproduce the original airflow, heat-spreader, and copper conditions before increasing logic utilization or clock rate. Measure board temperature in the fully populated enclosure and retain margin for industrial transients. If the package is reworked or substituted, treat the thermal solution as unverified until the replacement package and power profile are characterized.
The target uses a 1508-pin FC-FBGA package, so a complete official ball map and land pattern are required before layout. Confirm the orientation marker, ball numbering, power and ground assignments, differential-pair rules, escape strategy, and via-in-pad manufacturing capability. Preserve the existing board artwork for a direct maintenance replacement. The supplied data does not include package dimensions or pin names, so pinout is null and the exact package drawing must be obtained from the manufacturer documentation.
The 1,060 programmable I/O pins make power delivery and signal integrity as important as logic capacity. Match the I/O voltage and electrical standard to the original design, verify series termination where required, and control simultaneous-switching noise on wide parallel buses. Use controlled-impedance routing for high-speed or long-distance nets, maintain solid reference planes, and avoid routing clock and high-transition signals across plane splits. The supplied data does not provide supported I/O standards or timing limits, so use the manufacturer pinout and timing tables for final values.
Do not treat a shortened ordering code, a BGA suffix, or a generic Altera family listing as proof of drop-in compatibility. Confirm the exact MPN, 1508-pin ball map, speed grade, temperature grade, configuration interface, and power requirements for any alternative. EP2A70B724I7 is not established as a direct substitute, and EP2A70F1508C7ES and EP2A70F1508C6 require suffix-level verification. For a new design, prefer a supported FPGA family and plan firmware conversion rather than relying on an obsolete legacy part.
Compliance Information
The verified web data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields are therefore unknown rather than assumed.
