EP2A70B724C9N Présentation
A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that can be re-programmed to implement arbitrary digital logic functions. FPGAs sit in the digital IC hierarchy as: FPGA -> Programmable Logic Device (PLD) -> Logic IC -> Integrated Circuit -> Semiconductor. The APEX II family targets high-performance, multi-gate designs such as telecommunication infrastructure, high-speed datapath processing, and ASIC prototyping, bridging the gap between mid-range CPLDs and full custom ASICs.
Key features include 3 M system gates, 67,200 logic cells, embedded memory blocks, four phase-locked loops (PLLs) for clock management, multi-standard I/O support including LVDS, and 198 MHz internal operation. The 0.15 µm process technology reduces die size while delivering low static power, and the FCBGA-724 package offers a thermal-resistance advantage suitable for high-utilization designs. Each APEX II device is built around Look-Up Table (LUT)-based logic elements combined with a hierarchical interconnect fabric optimized for predictable timing closure.
The architecture combines LUT-based logic elements, embedded system blocks (ESBs) for RAM/ROM, fast interconnect, and on-chip PLLs for clock synthesis. This combination enables designers to absorb entire subsystems — including memory controllers, datapath engines, and bus interfaces — into a single device, eliminating the need for multiple CPLDs or ASIC gates. The 3 M system-gate rating positions the EP2A70 well above mid-range FPGAs in capacity and below high-end Stratix-class devices.
Typical applications include telecommunications line cards, ASIC prototyping, high-speed image processing pipelines, network switches/routers, and DSP co-processing. The 724-pin FCBGA package supports dense I/O layouts required by parallel bus architectures and high-pin-count memory interfaces. APEX II devices are commonly deployed in designs migrated from APEX 20KE families where higher logic density or extended I/O is needed.
When designing with this part, ensure robust 1.5 V core power decoupling with low-ESR ceramic capacitors placed adjacent to every VCC/VCCIO pin pair. The FCBGA-724 package requires controlled-impedance PCB stack-up and microvia technology; reflow profile must respect the 724-ball mass and the moisture sensitivity level (MSL) preconditioning. Signal integrity at 198 MHz operation demands matched-length routing and proper termination on LVDS pairs.

Applications typiques
EP2A70B724C9N convient pour 6 applications: Telecommunications Line Card Processing, ASIC Prototyping and Emulation, High-Speed Image Processing Pipeline, Network Switch and Router Fabric, DSP Co-Processing and Acceleration, Industrial Automation and Control.
Telecommunications Line Card Processing
The EP2A70B724C9N's 3 M system gates and 67,200 logic elements make it well-suited for telecom line-card datapath processing where parallel protocol handling and high-throughput state machines are required. The 198 MHz internal frequency and 536 user I/O lines support multi-channel framers, traffic managers, and ATM/Packet-over-SONET interfaces. PLLs allow recovery of multiple telecom-grade clocks from a single reference oscillator, simplifying board-level clock trees. Compared to a CPLD stack, the APEX II absorbs the entire line-card glue logic plus protocol-aware datapath into one device, reducing board area and BOM cost in legacy telecom infrastructure.

ASIC Prototyping and Emulation
Engineers use the EP2A70B724C9N as an ASIC prototype platform because its 3 M system gates can map large ASIC RTL blocks at near-final timing. The 0.15 µm CMOS process and APEX II architecture are well-characterized, and Quartus II provides mature synthesis, place-and-route, and timing-analysis flows that allow engineers to validate an ASIC before committing to mask costs. The 724-pin FCBGA exposes up to 536 I/O, which is enough to emulate wide ASIC busses and external memory interfaces. This drastically reduces pre-silicon verification risk by running real-world workloads on FPGA hardware months before ASIC tape-out.
Recommandé
High-Speed Image Processing Pipeline
The 3 M system gates and 198 MHz fabric of the EP2A70B724C9N can absorb real-time image processing pipelines for medical imaging, machine vision, and broadcast video. Its 536 user I/O support wide parallel sensor buses, while embedded memory blocks (ESBs) provide on-chip line buffers and convolution kernels to minimize external memory accesses. The four PLLs generate pixel clocks, line-sync timing, and DDR memory clocks from a common reference. Compared with discrete DSP+ASIC solutions, a single APEX II FPGA simplifies PCB layout and allows late-stage algorithm changes by re-programming the device.
Recommandé
Network Switch and Router Fabric
The EP2A70B724C9N is well-matched to mid-range network switches and routers because its 67,200 logic elements can implement multi-port MACs, lookup engines, and QoS schedulers while the 536 I/O lines provide direct parallel connectivity to PHY devices and switch fabrics. The 198 MHz fabric supports gigabit-rate packet processing with deterministic latency, and PLLs synthesize multiple port-rate clocks from one reference. The 724-pin FCBGA package also enables direct attach to high-density parallel busses like SPI-4.2 or Interlaken, which legacy switch ASICs commonly expose.
Recommandé
DSP Co-Processing and Acceleration
The EP2A70B724C9N's 3 M system gates and 67,200 logic elements can implement multi-channel FIR/IIR filters, FFT engines, and radar/wireless baseband blocks as FPGA co-processors paired with a host CPU or DSP. The 198 MHz fabric and embedded ESBs allow sustained 16-bit MAC operations at sample rates suitable for voice-band, ultrasonic, and narrowband radio processing. Four PLLs generate the multiple sample-rate clocks needed in multi-mode radios. Compared with running the same workload in software, an APEX II co-processor reduces host-CPU load and improves deterministic response in real-time DSP chains.
Recommandé
Industrial Automation and Control
The EP2A70B724C9N suits industrial automation controllers where deterministic, parallel I/O handling, motor-control PWM generation, and protocol bridging are required in a single device. The 536 user I/O can directly drive multi-axis stepper/servo interfaces, encoder counters, and field-bus transceivers. The 198 MHz fabric allows closed-loop control loops at sub-microsecond period, while PLLs generate precisely phased PWM carriers. Housed in a robust FCBGA-724 package, the device is appropriate for industrial-grade hardware when paired with proper thermal management and conformal coating.

Notes de conception
Estimated: at 198 MHz with 67,200 logic elements at typical 30% toggle rate, the EP2A70B724C9N core draws approximately 1.5–2.5 A from the 1.5 V VCCINT rail. Designers must provide low-impedance power delivery with at least four 10 µF X5R ceramic capacitors and one 47 µF tantalum bulk capacitor placed adjacent to the package. Independent VCCIO rails for each I/O bank are required if multiple I/O standards coexist; place 0.1 µF + 10 µF decoupling per VCCIO pin pair to suppress switching noise.
The 724-pin FCBGA package demands a controlled-impedance PCB stack-up with microvia technology for breakout routing. Use a 1.0 mm or 1.27 mm pitch BGA fan-out with at least two routing layers and a continuous ground plane directly under the device to control return paths. Matched-length routing (±50 mil tolerance) is required for any LVDS or high-speed parallel bus at 100 MHz+. Reflow profile must respect J-STD-020 moisture sensitivity; FCBGA devices typically require MSL-3 or better handling and dry-pack storage before assembly.
Estimated: at full 198 MHz operation with the entire fabric active, the EP2A70B724C9N dissipates approximately 4–6 W through its FCBGA-724 thermal pad. Designers should attach the central thermal pad to a 1 oz copper inner-plane via a 4×4 thermal via array (0.3 mm drill, 0.5 mm pitch) to spread heat to the opposite-side copper pour. Forced-air cooling or a low-profile heatsink is recommended for ambient temperatures above 55 °C or for fully enclosed industrial enclosures without airflow.
Do not exceed the maximum I/O bank current limit when assigning LVDS or PCI signals to one side of the device. Configuration mode selection (PS, AS, JTAG) must be set with proper pull-up/pull-down resistors during board bring-up, or the device may fail to enter user mode. Always check the Quartus II fitter report for unrouted nets before committing to board layout — APEX II routing congestion around embedded memory blocks is a frequent cause of timing closure failures. The device is NRNR as of 2026-09-08, so production designs should plan a migration path to a Cyclone or Stratix family.
