EP2A70F1736C8 Обзор
A Field-Programmable Gate Array (FPGA) is a programmable logic device built from configurable logic blocks (CLBs), programmable interconnect, and I/O cells that can be rewired post-manufacturing to implement arbitrary digital circuits. APEX II extends this with dedicated memory, PLLs, and high-speed interfaces, occupying a tier between classical FPGAs and ASICs in the programmable logic taxonomy (PAL/CPLD -> FPGA -> SoC FPGA -> ASIC). APEX II was Intel's (Altera) flagship high-density FPGA family of the early 2000s.
Key features of the EP2A70F1736C8 include 67,200 logic elements, 1,146,880 embedded RAM bits, MultiCore interconnect architecture, and support for high-speed LVDS and external SRAM interfaces. The FC-BGA-1736 package supports the I/O density required for memory-rich applications such as telecommunications switching and high-speed data acquisition, while industrial-grade operating range (0°C to 85°C TJ) covers workstation, telecom, and instrumentation deployments.
The device uses a Look-Up Table (LUT)-based logic fabric with embedded RAM blocks and a high-speed MultiCore interconnect that routes between Logic Array Blocks (LABs) and Embedded System Blocks (ESBs). This architecture supports concurrent processing of wide data paths, common in DSP and packet-processing designs, while the 1736-ball package preserves signal integrity for high fan-out designs.
Typical applications include high-speed telecommunications switching, ASIC prototyping, DSP pipeline implementation, and high-density glue-logic consolidation. The high LE count makes it applicable for designs previously requiring multiple CPLDs or smaller FPGAs, replacing them with a single component for cost and board-space reduction.
When designing with this device, ensure the Quartus design toolchain version is current for APEX II support, since legacy device support has been deprecated in newer Quartus releases. Plan for I/O bank VCCIO voltage partitioning and confirm configuration scheme (PS, JTAG, or PPA) compatibility with board infrastructure.
This page synthesizes distributor pricing, drop-in APEX II alternatives from the same product family, and practical design notes not found in the manufacturer datasheet, enabling engineers to evaluate the part for both legacy maintenance and new design opportunities.

Типичное применение
EP2A70F1736C8 подходит для 6 применениеs: ASIC Prototyping, Telecommunications Switching, High-Speed DSP Pipeline Implementation, High-Density Glue Logic Consolidation, Industrial Test and Measurement Instrumentation, Legacy System Maintenance and Field Upgrades.
ASIC Prototyping
The EP2A70F1736C8's 67,200 logic elements and 1,146,880 bits of embedded RAM make it a viable ASIC prototyping platform for designs targeting 50K-100K gate-equivalent ASICs, allowing pre-silicon verification with real-world timing. According to the APEX II datasheet, the device's LUT-based logic fabric and MultiCore interconnect enable concurrent implementation of wide datapaths, control logic, and embedded memory blocks on a single die. The FC-BGA-1736 package supports the I/O fan-out required for ASIC prototype bring-up, with LVTTL/LVCMOS/LVDS I/O standards accommodating mixed-logic interfaces. Engineers typically use Quartus II design tools with APEX II device support for synthesis, place-and-route, and timing closure, achieving ASIC-representative timing within 10-20% of the final silicon.

Telecommunications Switching
Telecommunications switching fabrics benefit from the EP2A70F1736C8's high LE density and MultiCore interconnect, which together route cell/frame traffic at line rates up to several hundred MHz. Per the APEX II datasheet, the embedded RAM blocks (1,146,880 bits total) implement cell buffers, lookup tables, and queue memory directly in the FPGA, eliminating external SRAM in many configurations and reducing board complexity. LVDS I/O support enables direct interfacing with serializer/deserializer (SERDES) companion chips for OC-48/STM-16 and similar telecom line rates. Commercial-grade 0°C-85°C operation covers central-office and customer-premises equipment (CPE) deployments.

High-Speed DSP Pipeline Implementation
The EP2A70F1736C8 implements DSP pipelines such as FFTs, FIR filters, and baseband modems using dedicated logic fabric combined with embedded memory for coefficient storage and delay lines. According to the APEX II datasheet, the 67,200 LEs deliver hundreds of 18x18 multiplier-equivalents when synthesized from LEs and carry chains, sufficient for mid-complexity DSP pipelines up to 50-100 MSPS. The MultiCore interconnect routes data between pipeline stages with deterministic timing, supporting streaming architectures where each clock cycle must be accounted for. The 1.5 V core and low-power CMOS process suit thermally-constrained DSP cards.
Рекомендуется
High-Density Glue Logic Consolidation
Designs that previously required multiple CPLDs or smaller FPGAs (e.g., 10K30, 10K50, EPF10K series) can consolidate onto a single EP2A70F1736C8, reducing board area, BOM cost, and inter-chip routing complexity. The 67,200 LEs can absorb address decoding, bus arbitration, interrupt steering, and peripheral control logic that traditionally spanned several programmable devices. Per the APEX II datasheet, the MultiCore architecture supports multiple clock domains simultaneously, allowing consolidation of synchronous and asynchronous logic without timing-domain violations. Commercial-grade operation and a wide I/O standard menu (LVTTL/LVCMOS/LVDS/SSTL) cover most glue-logic use cases.
Рекомендуется
Industrial Test and Measurement Instrumentation
Test and measurement instruments (logic analyzers, protocol analyzers, ATE) leverage the EP2A70F1736C8's high LE count and embedded RAM to implement capture buffers, pattern generators, and protocol-state machines. Per the APEX II datasheet, the 1,146,880 embedded RAM bits provide deep capture buffers without external SRAM, while LVDS I/Os interface directly with high-speed ADCs and DACs in the 100-500 MSPS range. The FC-BGA-1736 package's signal integrity supports multi-hundred-MHz clock rates critical for high-fidelity capture. The commercial 0°C-85°C range covers lab and factory-floor environments.
Рекомендуется
Legacy System Maintenance and Field Upgrades
Field-deployed telecom, aerospace, and industrial systems built on APEX II continue to require EP2A70F1736C8 for spare-part replacement, capacity upgrades, and field retrofits. Per Intel's legacy product support program, the device remains available through secondary-market distributors for maintenance purposes, though not for new designs. The FC-BGA-1736 footprint is solder-compatible across the speed-grade family (C7/C8/C9), simplifying inventory management for service organizations. Functional verification of replacement parts is mandatory given the obsolete lifecycle status.

Заметки по проектированию
The EP2A70F1736C8 is obsolete. Per Intel's legacy product support, the part is no longer manufactured. For new designs, choose Stratix IV/V or Cyclone 10/IV/V as modern replacements with active lifecycle. Using EP2A70F1736C8 in new production carries supply-chain uncertainty and counterfeit exposure risk.
Estimated: at typical APEX II utilization (~70% LE, 50% RAM) with 1.5 V core and 100 MHz internal clock, the device dissipates approximately 2-3 W. Per APEX II datasheet, the FC-BGA-1736 package requires a thermal management strategy combining PCB copper pour, internal ground/power planes, and possibly heatsink attachment for full-power operation. Designers should consult the APEX II thermal model for application-specific thermal budgets.
The FC-BGA-1736 package requires 0.8 mm or finer ball pitch PCB technology with microvia stackups and controlled-impedance routing. Per APEX II datasheet and JEDEC BGA design guidelines, designers should use 4-6 layer stackup with continuous ground/power planes under the BGA field. Signal integrity for LVDS interfaces requires 100 Ω differential impedance and matched trace lengths.
Speed grades within APEX II (C6/C7/C8/C9) are NOT software-compatible at the bitstream level. Per APEX II datasheet, each speed grade has a unique device ID and configuration bitstream. Re-programming is required when migrating between speed grades, even if the package and pinout are identical. Verify Quartus II programming file generation matches the target speed grade.
