An FPGA (Field Programmable Gate Array) is a type of programmable logic device that allows designers to implement custom digital circuits through configuration of internal logic blocks, embedded memory, and routing resources. APEX II sits in the hierarchy: FPGA -> programmable logic -> logic IC -> integrated circuit -> semiconductor, and is widely used as a flexible ASIC replacement in high-performance digital designs where time-to-market and design flexibility outweigh pure unit-cost optimization.
Key differentiating features include 1,146,880 system gates, 67,200 logic elements, embedded system blocks (ESBs) implementing dual-port RAM, ROM, FIFO and CAM, and 1,060 maximum user I/O. The -8 speed grade corresponds to approximately 100 MHz internal operation in APEX II silicon. The device supports multiple I/O standards including LVTTL, LVCMOS, PCI, SSTL, and LVDS through dedicated I/O banks.
The APEX II architecture combines a MultiCore interconnect fabric with embedded system blocks for memory-intensive functions. Each ESB provides up to 2,048 bits of dual-port RAM, and the embedded multipliers plus PLLs support DSP-style signal processing and clock management. The 1508-FCBGA package exposes the largest I/O count in the family, enabling high-bandwidth parallel interfaces.
Typical applications include high-speed communication ASIC prototyping, telecom line-card glue logic, industrial vision and image-processing pipelines, ASIC emulation, and high-performance data-path acceleration. The large gate count supports entire subsystems (RISC soft-cores plus peripherals) on a single device.
When designing with this part, plan power integrity carefully: a fully populated EP2A70 can exceed 2-3 A core current with transients during configuration. Use a multi-layer PCB with dedicated power planes and bulk ceramic decoupling at the FCBGA's underside balls.

典型應用
EP2A70F1508C8ES 適用於 6 應用s: Telecom Line-Card Glue Logic, ASIC Emulation and Prototyping, High-Speed Industrial Imaging Pipeline, DSP-Style Signal Processing Accelerator, Data-Path Acceleration in Storage Systems, Legacy Industrial Control and Test.
Telecom Line-Card Glue Logic
The EP2A70F1508C8ES's 1,146,880 system gates and 1,060 user I/O make it ideal for telecom line-card glue logic where many disparate interfaces must be bridged. With 67,200 LEs available, designers can integrate multiple interface bridges (Utopia, POS-PHY, SerDes glue) plus framing logic and a soft RISC controller on a single device. The 1508-FCBGA package supports the high pin count needed for parallel data buses plus LVDS serial links, while the -8 speed grade (~100 MHz Fmax) is sufficient for most line-card glue functions. Its SRAM-based configuration allows field upgrades when protocol revisions arrive.
推薦
ASIC Emulation and Prototyping
With 67,200 logic elements plus embedded dual-port RAM blocks, the EP2A70F1508C8ES serves as a multi-million-gate ASIC emulator for pre-silicon validation. Designers partition an ASIC RTL design across one or more EP2A70 devices, using the abundant ESB memory to model ASIC SRAM blocks. The 1508-FCBGA exposes all 1,060 user I/O for prototype boundary-scan, and the -8 speed grade supports emulation clock rates typically limited by ASIC floorplan rather than FPGA Fmax. Quartus II legacy support includes multi-FPGA partitioning flows for larger ASIC designs.
推薦
High-Speed Industrial Imaging Pipeline
The EP2A70F1508C8ES's high logic density and 1,060 I/O suit industrial machine-vision pipelines where multiple Camera Link or LVDS image sensors must be aggregated, processed, and forwarded over Gigabit Ethernet or fibre channel. The ESB dual-port RAMs act as line buffers between sensor FIFOs and the processing datapath, while the 67,200 LEs implement image preprocessing (white balance, Bayer demosaic, edge detection). The 1508-FCBGA package provides the routing density for wide parallel sensor buses plus LVDS high-speed serial links, all under -8 speed grade timing.
推薦
DSP-Style Signal Processing Accelerator
The APEX II architecture's embedded system blocks and abundant logic make the EP2A70F1508C8ES a capable co-processor for DSP-style workloads such as radar baseband processing, software-defined radio channelizers, or polyphase filterbanks. Each ESB can implement 2,048 bits of dual-port RAM used as coefficient or data buffers, while the LE fabric hosts the arithmetic datapath. The -8 speed grade enables approximately 100 MHz operation, sufficient for moderate-bandwidth channelization. The 1508-FCBGA exposes sufficient LVDS pairs for high-speed data ingress from front-end ADCs.
推薦
Data-Path Acceleration in Storage Systems
Storage system designers use the EP2A70F1508C8ES to accelerate data-path functions such as RAID XOR, encryption (AES), and Reed-Solomon encoding, where the 67,200 LEs implement datapath state machines and the ESBs hold intermediate operands. The 1508-FCBGA's 1,060 I/O expose multiple SAS/SATA host interfaces and DDR memory channels in parallel, enabling sustained multi-gigabyte-per-second throughput. The -8 speed grade sustains the clock rates needed for line-rate processing on 6 Gb/s SAS links, and the SRAM programmability allows field-upgrading codec implementations as standards evolve.
推薦
Legacy Industrial Control and Test
The EP2A70F1508C8ES continues to serve in long-lifecycle industrial controllers and ATE platforms where the original design cannot be respun. Its 67,200 LEs handle custom test-pattern generation, fixture control, and instrument-bus bridging in legacy ATE platforms. The -8 speed grade provides deterministic timing suitable for instrumentation synchronization, while the 1508-FCBGA's high pin count to drive fixture I/O without external muxing. SRAM configurability enables field updates when test programs change.

主要差異化特點
- Highest-density APEX II device in 1508-FCBGA package (對比EP2A40F1508C8ES)
- Balanced -8 speed grade vs faster -7 (對比EP2A70F1508C7)
- ES extended-screening variant (對比EP2A70F1508C8)
設計說明
The EP2A70F1508C8ES core can pull 2-3 A at 1.5 V under full switching activity, with large transient currents during SRAM configuration. Use a multi-layer PCB with a dedicated 1.5 V plane and place bulk ceramic capacitors (>= 100 uF total) directly under the FCBGA footprint. Decoupling: 0.1 uF X7R at every active VCCIO ball group, plus 10 uF bulk per bank. Estimated: at VIN=1.5 V, ICC=2.5 A, total core power ~3.75 W plus I/O bank power.
The 1508-FCBGA package has a typical theta-JA of approximately 8-12 C/W (exact value [DATA_NEEDED] from APEX II thermal model) when mounted on a 4-layer JEDEC test board with thermal vias. Total device power can exceed 5 W under sustained high activity, requiring either forced-air cooling or a heat spreader. Place 4 thermal vias minimum under the central die-expose region to pull heat into an inner copper plane.
FCBGA 1508 assembly with 1.0 mm or finer ball pitch demands careful PCB fabrication: microvia or stacked-via technology is required for inner-row fan-out, and ENIG or OSP surface finish is recommended for fine-pitch BGA reliability. Use 0.4 mm-diameter solder mask-defined (SMD) pads, and run X-ray inspection on assembled boards to verify joint integrity under the central balls (which are not visually inspectable).
The APEX II MultiCore interconnect benefits from uniform routing density - avoid routing long parallel tracks over many rows, which consume scarce routing tracks and degrade Fmax. For high-speed I/O (DDR, LVDS), match trace impedance to 50 dΩ single-ended or 100 dΩ differential, and keep stubs shorter than 3 mm. Place series resistors at the FPGA driver pins for SSTL/SSTL-II outputs.
Do not assume the APEX II family is still in production - it has been moved to last-time-buy by Intel. Always check the latest PCN before committing to a new design. The -8 speed grade is the baseline; faster -7 grade provides only ~10-15% Fmax improvement at higher dynamic power, so do not over-specify. Finally, ensure JTAG chain integrity: APEX II JTAG pins require external 1k pull-ups to VCCIO of the JTAG bank for reliable configuration.
