A Field-Programmable Gate Array (FPGA) is a reprogrammable digital logic IC that lets designers implement custom combinational and sequential logic, memory blocks, and high-speed I/O by downloading a configuration bitstream. Within the broader semiconductor taxonomy, FPGAs sit under programmable logic devices (PLD) alongside CPLDs. APEX 20KE is the second-generation APEX family that introduced embedded system blocks (ESBs) for dual-port RAM and CAM, fast row/column interconnect, and True-LVDS support to bridge the gap between traditional FPGAs and ASIC-class system-on-chip designs.
Key specifications include 1,000,000 typical gates, 38,400 logic elements, 384 Kbits of embedded system block memory, 12 embedded multiplier/accumulator blocks, and 4 Phase-Locked Loops (PLLs). The -2 speed grade delivers approximately 350 MHz internal operation and 1.6 ns propagation delay, while the Industrial temperature range (suffix I) ensures operation across -40C to +100C. The 652-ball FineLine BGA measures 45 x 45 mm with 1.27 mm ball pitch and offers 488 user I/O pins, with each I/O supporting multiple I/O standards including LVTTL, LVCMOS, SSTL, HSTL, AGP, CTT, and True-LVDS.
The architecture combines a MultiCore architecture that fuses look-up tables, product-term logic, and embedded memory into a unified fabric. The 4 PLLs provide on-chip clock multiplication, division, phase shifting, and skew control. Configuration is supported via passive serial (PS), passive parallel synchronous (PPS), passive parallel asynchronous (PPA), and JTAG modes, allowing in-system programmability via standard configuration EPROMs or microprocessor interfaces.
Typical applications include telecommunications line cards and cross-connects, high-speed image and video processing pipelines, network routers and switches, DSP co-processing, custom peripheral bridges, and ASIC prototyping. The 488 user I/O enable direct parallel bus connection to microprocessors, memory controllers, and backplane transceivers.
When designing with this device, ensure the 652-ball BGA land pattern uses 1.27 mm pitch with non-solder-mask-defined (NSMD) pads for reliable assembly. Configuration must be planned using a configuration device such as the EPC2 or EPC16, or a microprocessor host. Signal integrity on 488 simultaneous switching I/Os requires careful power-plane decoupling and ground-bounce management.

典型應用
EP20K1000EBI652-2 適用於 7 應用s: Telecommunications Line Cards and Cross-Connects, High-Speed Image and Video Processing Pipelines, Network Router and Switch Backplanes, DSP Co-Processing and Custom Acceleration, ASIC Prototyping and Emulation, Custom Peripheral Bridges and Bus Adapters, Industrial Control and Factory Automation.
Telecommunications Line Cards and Cross-Connects
The EP20K1000EBI652-2 is well-suited to telecommunications line-card designs because of its 1M system gates, 488 user I/O, and 4 on-chip PLLs. The high user-I/O count lets the device connect directly to TDM backplanes, T1/E1 framers, and UTOPIA / POS-PHY interfaces without external bus muxing, while the 4 PLLs generate the multiple clock domains typically required by telecom line cards. Industrial temperature rating supports outside-plant equipment in controlled enclosures.
推薦
High-Speed Image and Video Processing Pipelines
With 38,400 logic elements, 4 PLLs, and dual-port RAM ESBs, the EP20K1000EBI652-2 supports real-time video processing pipelines at resolutions up to HD. Designers can implement line buffers, color-space converters, scaling filters, and overlay engines in a single device. The 488 user I/O accommodate wide parallel pixel buses (16/24/32-bit) to companion video ADCs, DACs, and display controllers, while the -2 speed grade delivers sufficient timing margin at typical video clock rates.
推薦
Network Router and Switch Backplanes
The 488 user I/O of the EP20K1000EBI652-2 make it ideal for router/switch backplane aggregation where many fast Ethernet, POS, or SERDES framer channels must be merged. The 4 PLLs derive independent clocks for ingress, egress, fabric, and management domains, while the abundant logic elements hold packet-classification engines, CAM-driven lookups, and QoS schedulers. Industrial temperature rating suits chassis-edge line cards in temperature-controlled but high-airflow environments.
推薦
DSP Co-Processing and Custom Acceleration
The EP20K1000EBI652-2 functions as a DSP co-processor when paired with a host CPU or DSP, offloading FFTs, FIR filters, and custom transforms via dual-port RAM ESBs and 12 embedded multiplier/accumulator blocks. With 1M system gates, designers can implement multi-channel filter banks and adaptive algorithms. The 4 PLLs synchronize to the host bus clock and to external ADC/DAC sample clocks for tightly-coherent data flow.
推薦
ASIC Prototyping and Emulation
Designers use the EP20K1000EBI652-2 for ASIC prototyping because of its 1M system gates, 38,400 logic elements, and 488 user I/O for breadboard emulation. Multiple FPGAs can be ganged to prototype larger ASICs, with the FineLine BGA supporting high-density board-level interconnect. Industrial temperature rating also allows prototypes to validate in harsh-environment qualification chambers before ASIC tape-out.
推薦
Custom Peripheral Bridges and Bus Adapters
With 488 user I/O and abundant logic, the EP20K1000EBI652-2 implements bridges between legacy microprocessors (e.g., 68K, PowerPC), industry-standard buses (PCI, VME), and modern peripherals (DDR, SATA, USB). The 4 PLLs let one device serve as both bus master and peripheral clock domain. Industrial temperature rating supports factory-floor controllers, medical imaging front-ends, and outdoor instrumentation.
推薦
Industrial Control and Factory Automation
The EP20K1000EBI652-2 hosts multi-axis motion controllers, PLC scan engines, and fieldbus interfaces in factory-automation controllers. Its 488 user I/O drive parallel encoder counters, solenoid drivers, and HMI displays without external bus muxing, and the 4 PLLs synchronize to encoder quadrature clocks, servo PWM, and fieldbus rates. Industrial -40C to +100C rating supports cabinet-internal and outdoor panel installations.

主要差異化特點
- Industrial temperature rating across full APEX 20KE family (對比EP20K1000EBC652-2X)
- Balanced -2 speed grade at lowest cost within the industrial tier (對比EP20K1000EBI652-2X)

設計說明
The 652-ball FineLine BGA uses 1.27 mm pitch with non-solder-mask-defined (NSMD) pads, which provide more reliable solder-joint formation than solder-mask-defined pads at this fine pitch. Use at least 4 mil (0.1 mm) trace-and-space design rules escaping the inner rows, and place 0.1 uF + 0.01 uF decoupling pairs within 100 mil of each power/ground ball pair. Estimate: 488 user I/O plus dedicated balls drive roughly 100+ decoupling capacitors on the FPGA side alone.
APEX 20KE devices at 350 MHz internal operation dissipate 3 to 6 W typical depending on toggle rate. With 1.8 V core and Industrial temperature rating, the junction-to-ambient thermal resistance must keep Tj below 100C. Estimate: assuming 4 W dissipation and theta_JA of 15 C/W for a 4-layer PCB with adequate thermal vias, junction temperature rises approximately 60C above ambient, so a maximum ambient of 40C is feasible without a heatsink.
Dedicate four PCB layers to solid power and ground planes under the BGA to minimize simultaneous-switching-output (SSO) noise. Use a 4-to-1 ratio between core and I/O decoupling capacitance: each I/O bank needs roughly 0.1 uF per 8 pins plus a single bulk 10 uF tantalum at the bank supply pin. Place the configuration EPROM (EPC2, EPC8, or EPC16) within 2 inches of the FPGA DATA pins to keep the passive-serial configuration bus clean.
Do not substitute a Cyclone- or Stratix-family bitstream on the APEX 20KE: the configuration bitstream format and JTAG IDCODE are completely different and will fail silently or brick the device. Use only Altera Quartus II versions 6.x through 13.x for APEX 20KE synthesis, since later Quartus versions dropped support. Always verify the configuration with the checksum verify command after programming because BGA solder defects often manifest as configuration failures.
The 488 user I/O switching simultaneously can generate ground-bounce exceeding 1 V if not properly bypassed. Series-terminate each output with 33 ohm resistors when driving long traces or backplane connectors. For True-LVDS pairs, maintain 100 ohm differential impedance with matched trace lengths within 50 mil of each other. The 4 PLLs each require a dedicated analog VCC pin decoupled by a ferrite bead and a 10 uF plus 0.1 uF capacitor pair.
