The device uses a 0.15 µm CMOS process, supports a 1.8 V core supply with 1.8/3.3 V I/O, and operates up to 375.94 MHz on internal logic. Per the verified datasheet summary, it is housed in a square BGA-652 with JESD-30 code S-PBGA-B652. An FPGA (Field-Programmable Gate Array) is a class of programmable logic device that lets designers configure arbitrary digital logic through SRAM-based configuration memory. FPGAs sit in the broader taxonomy of digital ICs > programmable logic > programmable logic device (PLD) > FPGA, and they compete with CPLDs and structured ASICs. The APEX 20KC family combines look-up-table (LUT)-based logic with embedded memory blocks (ESBs) and a MultiCore interconnect, enabling system-on-a-chip integration for glue logic, bus interfaces, DSP preprocessing, and high-speed I/O bridging. Key features of the EP20K400CB652I7 include: 16,640 logic elements, 400K typical gates, embedded system blocks (ESBs) configurable as dual-port RAM/FIFO/CAM, multi-standard I/O support, dedicated clock management circuitry, and JTAG-based in-system programmability (ISP). The 'I7' speed grade and 'I' industrial temperature suffix make it suitable for -40 °C to +100 °C operation, while the BGA-652 footprint delivers high signal density for data-path-heavy designs. Architecturally, the APEX 20KC family introduced a hierarchical MegaLAB structure grouping 16 Logic Elements (LEs) with one ESB, providing predictable timing and efficient silicon utilization for register-rich designs. The MultiCore interconnect allows deterministic routing across the die, simplifying static timing closure compared with older symmetric-array FPGAs. Typical applications include telecommunications line cards, industrial control and instrumentation, military/aerospace signal processing, high-speed data acquisition front-ends, and legacy replacement of ASICs where NRE cost is prohibitive. The 652-ball BGA also supports prototyping for ASIC emulation. When designing with this part, allocate sufficient PCB layers (>=6) for BGA fan-out and controlled-impedance routing; verify that your Quartus/MAX+PLUS II toolchain still supports the device, as the APEX 20KC family reached end-of-life and is now serviced through Intel's FPGA legacy support programs rather than active new design-ins.

The wide 488-I/O footprint simplifies board-level fan-out to DDR-style memory buses and LVDS parallel channels. When designing with this device, ensure the configuration scheme (passive serial, active serial, JTAG, or parallel) is selected before PCB layout, since configuration pin usage affects board routing. Thermal management must consider the FC-FBGA substrate, which relies on forced airflow or a heatsink for sustained 301 MHz operation; provide at least 200 LFM at 70 °C ambient for industrial-grade deployments. Decoupling must include 0.1 µF and 0.01 µF low-ESL ceramics within 5 mm of every VCC and VCCIO pin pair.

Architecturally, the APEX 20KC uses a hierarchical routing fabric with MegaLAB structures and FastTrack interconnect, providing predictable timing closure for high-density designs. Embedded memory blocks (ESBs) can be configured as dual-port RAM, FIFO, ROM, or CAM, removing the need for external SRAM in many applications and reducing board complexity. Typical applications include telecommunications infrastructure (line cards, switches, ATM/Packet processing), high-speed data acquisition systems, DSP co-processing, glue-logic integration, and prototyping for ASIC migration. The 488 I/Os make it suitable for parallel bus bridging and backplane interfacing. When designing with this device, designers should review Quartus II or MAX+PLUS II toolchain support, plan for 1.8 V core and MultiVolt I/O supplies, and ensure PCB layout can handle 1.0 mm BGA pitch with microvia technology. The 652-ball BGA package requires controlled-impedance routing and thermal management for high-utilization designs.

EP20K400CF672I9 - APEX 20KC FPGA, 400K Gates, 672-BGA | Intel
The Intel EP20K400CF672I9 is a member of the APEX 20KC family of Field Programmable Gate Arrays (FPGAs) that delivers 400,000 system gates, 16,640 logic elements, and a maximum operating frequency of 250 MHz, all packaged in a 672-ball FineLine BGA (FC-FBGA) with 1.0 mm pitch. Manufactured on a 0.15 µm CMOS process, this high-density programmable logic device targets high-performance data-path and communications designs. What is a Field Programmable Gate Array (FPGA)? An FPGA is a type of programmable logic device that allows designers to configure digital logic blocks and interconnects after manufacture. FPGAs sit in the hierarchy of programmable logic devices (PLDs) -> complex programmable logic devices (CPLDs) -> FPGAs -> SoC FPGAs -> semiconductor ICs. The APEX 20KC family specifically combines Look-Up Table (LUT)-based logic with embedded content-addressable memory (CAM) and dual-port RAM, bridging the gap between traditional FPGAs and ASICs. Key features of the EP20K400CF672I9 include 212,992 bits of embedded RAM, support for multiple I/O standards including LVTTL, LVCMOS, PCI, and LVDS, and an industrial-grade operating temperature range. The device supports 1.8 V core operation with selectable 1.8 V or 3.3 V I/O voltages, enabling flexible interfacing with surrounding digital logic. Its MultiVolt I/O architecture eliminates the need for external level shifters when bridging 1.8 V and 3.3 V domains. The APEX 20KC architecture combines logic elements (LEs) with embedded system blocks (ESBs), where each ESB can be configured as dual-port RAM, single-port RAM, ROM, or CAM. This embedded memory bandwidth is critical for high-speed packet processing, FIFOs, and digital signal processing (DSP) pipelines. With 16,640 logic cells and a 250 MHz core clock, the EP20K400CF672I9 provides enough headroom for designs that previously required multiple lower-density FPGAs. Typical applications include high-speed telecommunications switching, network routers and line cards, DSP co-processing, industrial automation controllers, and high-throughput data acquisition systems. The 672-BGA package and 250 MHz performance make it suitable for backbone equipment where I/O count and signal integrity matter. The I9 speed grade indicates an industrial operating range of -40°C to +85°C. When designing with this device, ensure proper power decoupling with bulk and high-frequency capacitors on each VCC and VCCIO rail, and follow Altera's PCB layout guidelines for fine-pitch BGA packages. Signal integrity on high-speed LVDS pairs requires impedance-controlled routing. The device is now in the legacy/obsolete lifecycle as APEX 20KC has been superseded by newer Cyclone and Stratix families.

The Altera (Intel) EP20K400CFC672-9 is a member of the APEX-20KC family of Field Programmable Gate Arrays, delivering 400,000 typical gates (1664 macrocells / logic elements) with embedded system block (ESB) memory and a 488-pin user I/O count in a 672-ball FineLine BGA package. The device operates from a 1.71 V to 1.89 V core supply and supports a commercial operating junction temperature grade of 0 °C to 85 °C. Speed grade -9 denotes the slowest commercial timing bin of the APEX-20KC family, used where timing margin is more important than raw performance. An FPGA (Field Programmable Gate Array) is a programmable logic device that combines configurable logic blocks (LEs), programmable routing, and embedded memory resources onto a single die. APEX-20KC is positioned in the broader taxonomy as: FPGA > Programmable Logic Device (PLD) > Logic IC > Integrated Circuit > Semiconductor. The -KC suffix denotes an enhanced-memory variant of APEX-20K with embedded system blocks capable of dual-port RAM, content-addressable memory (CAM), and product-term logic, extending the device into datapath-intensive applications. Key features of the EP20K400CFC672-9 include 1664 logic elements, 212,992 bits of embedded memory distributed across ESBs, True-LVDS support, multi-voltage I/O (1.5 V, 1.8 V, 2.5 V, 3.3 V) with hot-socketing capability, four phase-locked loops (PLLs) for clock management, and the FastTrack continuous interconnect architecture. The 672-ball FCBGA at 27 mm × 27 mm body provides high-density I/O suitable for high-pin-count data-path and telecom designs. Typical applications for the EP20K400CFC672-9 include custom DSP datapaths, telecom line-card glue logic, broadband aggregation switches, PCI/PCI-X bus bridges, and custom processor peripheral controllers. The large ESB memory bank and 488 user I/Os make it well-suited for high-throughput parallel data-pump designs. Designers should review the APEX 20KC data sheet for Quartus II device support status, configuration scheme selection (EPC configuration devices or JTAG), and proper decoupling of the 1.8 V core rail and 3.3 V auxiliary supply. Devices of this family have been classified as not recommended for new designs (NRND) and should be replaced by Cyclone, Stratix, or Arria series parts for new programs.
