EP20K600CB652C9N - 600K Gates APEX 20KC FPGA, BGA-652 | Intel
The Intel EP20K600CB652C9N is a high-density APEX 20KC family programmable logic device (PLD) manufactured on a 0.15-micrometer all-layer copper-metal process, delivering approximately 600,000 typical ASIC gates (system gates) and 24,320 logic elements across a 652-ball FineLine BGA package measuring 45 x 45 mm with a 1.27 mm terminal pitch. The 'C9' speed grade corresponds to roughly a 1.48 ns propagation delay per AiPCBA's datasheet mirror, and the part exposes 488 user I/O pins. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), embedded memory blocks, and programmable interconnect that the customer can tailor after manufacture using a hardware description language. FPGAs occupy the programmable-logic tier between fixed-function ASICs and software-defined processors, making them the platform of choice for parallel datapaths, custom interfaces, and pre-silicon prototyping. Within Intel's portfolio, the APEX 20KC series sits at the top of the APEX II architecture family, integrating MultiCore elements that pair 4-input look-up-table (LUT) logic with embedded system memory (ESB) for FIFO and dual-port RAM functions. Key features of the EP20K600CB652C9N include approximately 600K typical gates, 24,320 logic cells (LEs), embedded system memory blocks, MultiCore LUT-plus-memory architecture, pin compatibility with the earlier APEX 20KE series, 1.8 V core supply, JTAG-based in-system programmability through IEEE 1149.1, and 488 user I/Os supporting LVTTL, LVCMOS, PCI, and other common I/O standards. The 0.15-micrometer copper process yields roughly 25 to 35 percent higher performance than the older APEX 20KE family, while preserving board-level compatibility for migration. The architecture couples four-input LUTs with embedded memory so each logic element can be partitioned between combinatorial logic and on-chip storage, and the high I/O count supports wide parallel buses such as DDR memory interfaces and multi-channel telecom datapaths. The 652-ball BGA package supplies the high pin density required to bring 488 user I/Os to the board without exceeding routable escape density on standard 4-layer FR-4 stack-ups. Typical applications include telecom line cards, high-speed image processing pipelines, ASIC prototyping, custom DSP accelerators, and pre-production verification platforms. The commercial temperature grade (0 to 85 C) targets indoor rack-mounted equipment rather than automotive or military environments. Designers should budget for the large 45 x 45 mm PCB footprint, ensure the BGA land pattern follows JEDEC MS-034 for 1.27 mm pitch, and use Altera/Intel Quartus II software for place-and-route because legacy APEX series support was last shipped in Quartus II v13.0 and may require the legacy toolchain.

EP20K600CB652I7 - 600K Gate APEX 20KC FPGA BGA-652 | Intel
The Intel EP20K600CB652I7 is a member of the APEX 20KC family of CMOS SRAM-based Field-Programmable Gate Arrays (FPGAs), delivering 600,000 system gates in a 652-ball FineLine BGA package. Built on a 0.15 µm process and running on a 1.8 V core supply, the device integrates 24,320 logic elements and is specified for a maximum internal frequency of 375.94 MHz at the -7 speed grade. The 'I' suffix denotes the industrial operating temperature grade and '7' denotes the speed bin. An APEX 20KC FPGA is a programmable logic device that combines look-up table (LUT) based logic elements, embedded system blocks (ESBs) for memory and specialized functions, and a high-bandwidth MultiCore interconnect. The APEX family sits within the broader taxonomy of programmable logic -> FPGA -> SRAM-based FPGA -> PLD (programmable logic device) -> semiconductor, and is the predecessor to the Stratix/Arria series that Intel (formerly Altera) ships today. APEX 20KC was widely used in telecom line cards, DSP front-ends, and high-speed bus bridges during the early 2000s. Key differentiating features of the EP20K600CB652I7 include 488 user I/O pins (4 dedicated inputs plus 480 I/O lines), four embedded PLL-style clock blocks per row, embedded system blocks configurable as dual-port RAM, ROM, or CAM, MultiVolt I/O support for interfacing with 1.8 V, 2.5 V, 3.3 V, and 5.0 V buses, and JTAG-based IEEE 1149.1 boundary-scan plus in-system programmability. The 652-ball FineLine BGA exposes a generous number of differential pairs and global clock networks, which is why the part was popular in communications infrastructure. In terms of architecture depth, the 24,320 logic elements are organised into MegaLAB structures of 16 Logic Array Blocks (LABs), each LAB containing 10 Logic Elements (LEs). ESBs can be configured as 4 Kbit memory blocks, and the MultiCore interconnect provides predictable routing delays that scale with fan-out rather than die position, simplifying timing closure versus earlier FPGAs. Typical applications include telecommunications backplane glue logic, high-speed serial protocol bridging (UTOPIA, POS-PHY, SPI-4.2), DSP co-processing front-ends, image and video pipeline processing, and PCI bus bridging. The wide I/O count also makes it well suited to test instrumentation and ASIC prototyping platforms. When designing with the EP20K600CB652I7, ensure the 1.8 V core rail has bulk decoupling close to the BGA, provide proper MultiVolt reference biasing for any 5 V-tolerant banks, and respect the JTAG chain ordering if the device is cascaded with other programmable logic on the board. A thermal copper pour under the BGA is recommended because the -7 industrial speed grade can dissipate several watts under full utilisation.

Key features include 24,320 logic elements, 311,040 bits of embedded system block memory, four Phase-Locked Loops (PLLs), and a low-voltage 1.8 V core with multi-voltage I/O support. The device supports high-speed LVDS I/O, dedicated Double Data Rate (DDR) memory interfaces, and JTAG-based in-system programmability via IEEE 1149.1, making it suitable for I/O-intensive designs. Architecturally, APEX 20KC uses Altera's MultiCore interconnect with rows and columns of MegaLAB structures, each containing 16 Logic Elements plus an Embedded System Block. The 0.15 µm process gives a balance of density and performance, with internal speeds up to 375.94 MHz. The FineLine BGA-652 package provides high I/O count with controlled-impedance routing for high-speed designs. Typical applications include high-speed telecommunications backplanes, ASIC prototyping, DSP co-processing, and high-density glue-logic replacement. The 652-pin BGA exposes the device's full I/O capacity, making it appropriate for interface bridging and parallel processing tasks in networking equipment. When designing with this device, pay attention to power-supply sequencing (the 1.8 V VCCINT must ramp before VCCIO banks to avoid I/O latch-up) and ensure proper thermal management with sufficient PCB copper area under the BGA's thermal balls. Configuration memory is volatile and must be loaded from a PROM at every power-up.

The CB672 suffix denotes the 672-ball FCBGA (27 x 27 mm) package, while the C8 speed grade specifies an internal core speed of approximately 301 MHz. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnects, and dedicated silicon resources such as block RAM, DSP blocks, and high-speed transceivers. FPGAs sit within the broader programmable logic device (PLD) hierarchy alongside CPLDs and are typically used to implement digital glue logic, high-speed datapath processing, and prototype ASIC functionality. The APEX 20KC series sits between older APEX 20K and later Stratix/Arria families and is recognized as a high-density, low-power solution for telecom, networking, and DSP applications of the late 1990s and early 2000s. Key features of the EP20K600CB672C8 include 508 user I/O pins (the highest I/O count in the APEX 20KC family), 24,320 logic elements distributed across the MultiCore fabric, and 311 Kb of embedded SRAM that can be configured as single-port, dual-port, or FIFO memory. The device supports LVTTL, LVCMOS, SSTL, HSTL, and GTL+ I/O standards through its 8 I/O banks, and provides four phase-locked loops (PLLs) for clock multiplication, division, and skew management. Hot-socketing capability and 3.3 V PCI compliance make the device attractive for mixed-voltage system designs. Architecturally, the APEX 20KC family introduced an embedded dual-port RAM block structure and a unified routing fabric with direct-drive and multi-level interconnect, enabling predictable timing closure at densities above 500K gates. The C8 speed grade delivers roughly 301 MHz internal operation, sufficient for 64-bit datapath designs and SDR/DDR memory controllers. Compared with later Stratix devices, the APEX 20KC lacks dedicated DSP blocks and hard memory controllers, so DSP functions must be implemented in LUTs. Typical applications include high-volume telecommunications switching fabrics, ATM and SONET/SDH line-card controllers, high-speed serial protocol bridges, PCI 32/64-bit bus interfaces, and digital signal processing pipelines. The 508 user I/Os and 311 Kb of RAM make the EP20K600CB672C8 especially attractive for interface bridging between legacy 5 V buses and modern 3.3 V cores. Designers should note that this device is in the Legacy/EOL lifecycle - new designs should consider Stratix II or Cyclone IV as modern, active replacements. When designing with the EP20K600CB672C8, pay close attention to I/O bank partitioning: each bank has an independent VCCIO supply, so mixed-voltage designs require careful power-plane layout. Use Altera Quartus II 4.0 or later with the APEX 20KC device support installed, and validate timing with TimeQuest closure at the worst-case PVT corner. Decoupling requires at least 0.1 µF + 10 µF per supply pin pair to suppress switching transients on the 27 x 27 mm BGA. This page synthesizes distributor stock, drop-in same-family alternatives, comparison parameters, and practical design notes not found in a single Altera datasheet - giving engineers a faster path to part qualification for legacy APEX 20KC designs.

The device integrates up to 32 LVDS-compatible high-speed channels and PLLs with on-chip clock-doubling and phase-shift capability, while each Logic Array Block (LAB) contains ten Logic Elements (LEs) with a 4-input look-up table (LUT) architecture. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit built from an array of configurable logic blocks, embedded memory, routing interconnect and I/O cells that the designer programs after manufacture. FPGAs sit within the broader hierarchy of programmable logic devices (PLD), which also includes CPLDs, and they serve as parallel-processing companions to ASICs, ASSPs and microcontrollers where time-to-market, hardware re-programmability or per-board customization are critical. APEX-20KC parts are considered high-density members of the APEX-20K family, designed for datapath-intensive designs that combine wide datapaths, on-chip memory and high I/O counts. Key features include MultiVolt I/O support (1.8 V, 2.5 V and 3.3 V interfaces with a 2.5 V core), PCI-SIG compliant 3.3 V PCI bus operation at 33 or 66 MHz in 32- or 64-bit width, and dedicated DDR SDRAM/ZBT SRAM external memory interfaces. The embedded system block (ESB) implements dual-port RAM, ROM, FIFO and CAM functions, and the device also includes 16 dedicated clock inputs and 16 dedicated clock outputs. Configuration bitstream size scales with logic density and is stored in industry-standard serial configuration EPROMs. Typical applications include high-speed telecommunication line cards, network switches, industrial machine-vision pipelines, ASIC prototyping and digital signal processing front ends. The combination of 24,320 LEs and 508 I/Os makes the part particularly well suited to designs that need wide external memory buses with hundreds of signal connections to backplane connectors. Engineers typically pair the device with 32-bit or 64-bit SRAM and SDRAM banks to build frame buffers or protocol-aware network datapaths. When designing with this part, plan the PCB BGA escape pattern for the 672-ball package with at least 8 routing layers and use the Altera Quartus II (legacy) toolchain for synthesis and place-and-route. Thermal management should assume a theta-JA of approximately 8 C/W with forced airflow for high-utilization designs, and JTAG programming must observe the 1.8/2.5/3.3 V VCCIO ramp sequencing noted in the APEX-20KC datasheet.

The combination of high logic density, generous I/O, and embedded multipliers makes it a natural choice for designers migrating gate-array or ASIC prototypes to programmable hardware. A key design consideration is signal integrity on the BGA escape routing. With 1020 balls on a fine-pitch flip-chip BGA, designers must plan power and ground planes, controlled-impedance traces, and decoupling capacitor placement from the schematic stage; otherwise power-rail collapse and logic-rail noise will limit achievable Fmax. Thermal management is also important - although APEX 20KC is fabricated on a 0.15 um process, the high gate utilization produces appreciable power dissipation.

The wide gate count and embedded memory make it ideal for designs requiring parallel processing and fast on-chip storage without external SRAM. When designing with the EP20K600CF33C7N, ensure thermal management via PCB copper pour and airflow, follow Intel/Altera configuration guidelines (PS configuration mode or JTAG), and account for the 33 mm × 33 mm BGA pitch during PCB layout. The device is now mature; consider Cyclone or Stratix equivalents for new designs.
EP20K600CF33C8 - APEX 20KC FPGA, 600K Gates, 1.8V | Altera
The Altera EP20K600CF33C8 is a member of the APEX 20KC programmable logic device family, delivering 600,000 typical gates (system gates), 24,320 logic elements, and 311,296 RAM bits in a 1020-ball FineLine BGA package at -8 speed grade. It is fabricated on a 0.15 µm CMOS process with 1.8 V core and supports LVDS I/O with copper interconnect technology. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs), embedded memory blocks, and programmable I/O cells. FPGAs sit in the programmable logic hierarchy between CPLDs (smaller, non-volatile) and ASICs (high-volume, fixed-function). The APEX 20KC family specifically combines LUT-based logic with embedded memory, making it suitable for high-density data-path and DSP-style designs of its era, typically powered by an external linear or switching regulator such as a TI TPS7A4701. Key features of the EP20K600CF33C8 include 24,320 logic elements, 311,296 bits of embedded SRAM, MultiCore architecture with FastTrack routing, and LVDS I/O support up to 840 Mbps per channel. The device operates from a 1.8 V core supply with separate VCCIO banks for 1.8 V, 2.5 V, or 3.3 V I/O interfacing, and supports in-system programmability via IEEE 1532 or passive serial configuration modes. Up to four enhanced PLLs provide clock synthesis and skew management for high-speed designs. The EPEX 20KC architecture uses a MultiCore fabric where each MegaLAB structure combines 16 logic elements (LEs) with a shared embedded system block (ESB) that can be configured as either additional logic or dual-port RAM. This dual-role memory architecture, combined with FastTrack continuous interconnect routing, enables predictable timing closure for designs up to 600K gates with internal frequencies typically targeting 100-300 MHz in commercial FPGAs of this node. Typical applications include high-density data-path controllers, telecom switching fabrics, prototyping platforms for ASIC development, DSP co-processing cards, and industrial imaging pipelines. The wide I/O count and high gate density also make it useful for legacy systems requiring parallel bus interfaces, custom protocol bridging, or backplane glue logic in long-lifecycle programs. When designing with this device, note that the part is now classified NRND/EOL; long-term availability is restricted, and second-source or Altera/Intel migration paths should be evaluated early. Designers must respect simultaneous-switching output (SSO) limits on the 1020-ball BGA, maintain continuous ground stitching beneath the package, and configure unused pins per the datasheet (typically as tri-stated inputs) to minimize leakage. Power sequencing of VCCINT before VCCIO is also required.

EP20K600CF33C8N - 600K Gates APEX 20KC FPGA | Intel/Altera
The Intel (formerly Altera) EP20K600CF33C8N is a high-density APEX 20KC family Field-Programmable Gate Array (FPGA) delivering 600,000 system gates and 24,320 logic elements in a 1020-pin flip-chip BGA (FC-FBGA) package. It is fabricated on a 0.15 µm CMOS process and operates from a 1.8 V core supply, with embedded system blocks (ESBs) implementing dual-port RAM and True-LUT-based logic fabric. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that integrates configurable logic blocks (LABs), programmable routing, embedded memory, and dedicated I/O into a single semiconductor die. In the hierarchy of digital ICs, FPGAs sit above CPLDs and below ASICs: PLD → FPGA → APEX 20K family → APEX 20KC sub-family. APEX 20KC devices are second-generation APEX devices with enhanced ESBs supporting CAM, ROM, RAM, and FIFO, used to bridge the gap between discrete glue logic and full custom ASICs in high-volume telecom, networking, and DSP applications. Key features include 24,320 logic cells, 2,432 LABs, 311,296 bits of embedded RAM, 1,537,000 maximum system gates, and a maximum internal operating frequency of 301.21 MHz. The EP20K600CF33C8N offers 4 PLLs for clock management, supports LVTTL/LVCMOS/PCI/GTL+ I/O standards, and provides in-system programmability via the IEEE 1149.1 (JTAG) interface plus passive serial/parallel configuration modes. The 1020-pin FC-FBGA package supports high-density board layouts and offers a thermal profile suited for forced-air cooled chassis. Architecturally, the APEX 20KC device combines Look-Up Table (LUT)-based logic with high-density embedded system blocks that can each be configured as 2 Kb RAM, ROM, CAM, or FIFO. The 'CF33' suffix denotes flip-chip BGA packaging and 0.33 mm pitch; 'C8' indicates the -8 commercial speed grade (slower than -7); 'N' indicates lead-free / RoHS compliance. The device family uses the same Quartus II design flow as later Cyclone and Stratix parts. Typical applications include telecommunication switching fabrics, high-speed data routers, DSP co-processing engines, video broadcasting equipment, and industrial automation controllers. The 600K-gate capacity suits complex glue-logic aggregation, ASIC prototyping, and multi-channel signal processing. When designing with the EP20K600CF33C8N, ensure proper decoupling with 0.1 µF and 10 µF capacitors placed close to the 1.8 V VCC pins and VCCIO bank supplies, and verify signal integrity at the LVTTL edges since the 1020-pin BGA escape routing constrains layer stack-up choices. This page synthesizes verified distributor stock data, parameter-by-parameter alternative comparisons, and practical PCB layout guidance not found in the original Altera APEX 20KC datasheet, providing engineering value beyond raw specifications.
EP20K600CF33C9 - APEX 20KC FPGA 600K Gates, 1020-BGA | Intel
The Intel (formerly Altera) EP20K600CF33C9 is a high-density APEX 20KC family FPGA built on a 0.15 µm process, delivering up to 600,000 system gates, 24,320 logic elements, and 250 MHz core performance in a 1020-ball FC-FBGA package. It supports a 1.8 V core supply (1.71 V to 1.89 V) and provides up to 588 user I/O lines with 4 dedicated inputs and 580 general-purpose I/O, with a propagation delay of approximately 2.0 ns and a maximum clock frequency of 303.03 MHz per verified distributor data. An FPGA (Field Programmable Gate Array) is a reconfigurable semiconductor device containing an array of programmable logic blocks, embedded memory, and interconnect that an engineer can program post-manufacture to implement arbitrary digital logic. APEX 20KC sits within the FPGA category hierarchy: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit -> semiconductor. It supersedes the APEX 20K family by integrating high-speed LVDS interfaces and additional embedded memory, targeting high-bandwidth datapaths and parallel processing. Key features include 24,320 logic cells, 588 user I/O, LVDS-compatible I/O on selected banks, dedicated dual-port RAM blocks, and JTAG-based in-system programmability (ISP) via the IEEE 1149.1 boundary-scan interface. The 1020-ball FC-FBGA package exposes the full I/O count and supports high-speed signal integrity required by multi-gigabit parallel buses. Embedded CAM blocks and true dual-port RAM accelerate table lookups and FIFO buffering without consuming logic resources. Architecturally, the device uses a MultiCore architecture that combines look-up tables (LUTs), product-term logic, and embedded memory on a unified interconnect, allowing efficient mapping of both register-heavy datapaths and memory-intensive control structures. The 0.15 µm process and 1.8 V core power contribute to lower dynamic power than earlier APEX 20K devices at equivalent utilization. Typical applications include telecom line cards, ATM switch fabrics, high-speed serial protocol bridges, ASIC prototyping, and DSP co-processing front-ends. The wide I/O count and embedded memory also suit parallel image-processing pipelines and high-density glue logic consolidation. When designing, allocate JTAG access for ISP, place decoupling capacitors within 5 mm of every supply pin pair, and validate signal-integrity for simultaneous-switching outputs.
