EP20K200RC208-2 Overview
A Field Programmable Gate Array (FPGA) is a type of integrated circuit that can be configured by the customer or designer after manufacturing - hence "field-programmable". FPGAs occupy a hierarchy of programmable logic: programmable logic device (PLD) -> complex PLD (CPLD) -> FPGA -> system-on-chip FPGA. The APEX-20K family specifically combines look-up table (LUT) based logic with embedded memory blocks and a MultiCore architecture, allowing designers to implement glue logic, register-heavy datapaths, DSP blocks, and small to medium-sized microprocessors in a single device.
Key features of the EP20K200RC208-2 include 144 maximum user I/O pins, 8320 logic elements (LEs), 106,496 RAM bits organized into embedded array blocks (EABs), and in-system programmability through the IEEE 1149.1 JTAG interface plus Altera's legacy configuration scheme. The device supports multi-voltage I/O standards including LVTTL, LVCMOS, PCI, and GTL+ on a per-pin basis, enabling mixed-voltage system integration without external level shifters.
Architecturally, the EP20K200 implements Altera's MultiCore architecture with embedded array blocks (EABs) for memory and logic array blocks (LABs) routed via a continuous FastTrack interconnect. Each LE contains a 4-input LUT, a programmable register, and dedicated carry chain logic for arithmetic operations. The combination of LUT logic, EAB-based memory, and high fan-out routing makes the part well-suited to designs that require both moderate logic density and distributed RAM/ROM.
Typical applications include telecommunications line cards, industrial control and machine vision, legacy ASIC prototyping, low-volume networking routers, and embedded control in industrial automation. The exposed thermal pad (EP) on the 208-RQFP package aids heat dissipation, allowing reliable operation at industrial temperature ranges.
When designing with this part, ensure that the JTAG chain, configuration mode pins (MSEL), and power sequencing are correct for the chosen configuration EPROM. The APEX-20K family is now considered mature/legacy - designers should verify long-term availability through Rochester Electronics or franchised distributors and consider newer Cyclone or MAX series for new designs.

Typical Applications
EP20K200RC208-2 is suitable for 6 applications: Telecommunications Line Cards, Industrial Control and Machine Vision, Legacy ASIC Prototyping, Embedded Networking Routers, Test and Measurement Instrumentation, Aerospace and Defense Avionics (Legacy Sustainment).
Telecommunications Line Cards
The EP20K200RC208-2's 200K system gates and 106,496 bits of embedded SRAM suit telecom line cards that need moderate logic density, on-chip buffering, and PCI/LVTTL I/O for backplane interfaces. The 144 user I/O pins accommodate parallel bus connections to network processors, while the JTAG interface enables in-system firmware updates in deployed field units.
Recommended
Industrial Control and Machine Vision
Industrial PLC and machine-vision controllers benefit from the EP20K200RC208-2's 8320 LEs and embedded memory for pixel buffering, frame management, and motion-control state machines. The industrial temperature range (-40C to +85C) and exposed thermal pad support factory-floor thermal environments. The device's multi-standard I/O (LVTTL, LVCMOS, PCI) simplifies interfacing to industrial cameras, motor drivers, and sensor buses.
Recommended
Legacy ASIC Prototyping
Designers use the EP20K200RC208-2 as a prototyping vehicle for ASIC designs up to 200K gates, leveraging the 8,320 logic elements and 106,496 bits of embedded memory to validate RTL before committing to mask production. The 208-RQFP package allows hand-soldering or socketed prototype boards, and the JTAG chain supports rapid iteration cycles during pre-silicon validation.
Recommended
Embedded Networking Routers
Low-volume embedded routers and protocol bridges use the EP20K200RC208-2 to implement packet classification, queue management, and serial protocol termination. The 200K gates comfortably fit IPv4 forwarding tables and DMA controllers, while the 144 user I/O pins connect to PHY chips, SDRAM, and host processors. Industrial temperature and 3.3V I/O simplify integration into networking appliances.
Recommended
Test and Measurement Instrumentation
Test equipment such as protocol analyzers and data-acquisition front-ends use the EP20K200RC208-2 for waveform timing logic, trigger sequencers, and high-speed sample buffering. The 106,496 bits of embedded RAM serve as capture memory, and the 8320 LEs implement timing generators. The exposed thermal pad supports continuous operation at industrial temperatures during prolonged test campaigns.
Recommended
Aerospace and Defense Avionics (Legacy Sustainment)
Fielded avionics systems that originally used APEX-20K devices continue to be sustained using the EP20K200RC208-2 via Rochester Electronics and franchised distributors. The device's known reliability profile, stable supply chain, and JTAG-based in-system reprogrammability make it suitable for long-lifecycle defense platforms. New avionics designs should evaluate modern radiation-tolerant FPGAs instead.

Design Notes
The EP20K200RC208-2 requires separate VCCINT (core) and VCCIO (I/O) supplies. VCCINT is typically 2.5V for APEX-20K 0.18um devices, while VCCIO supports 3.3V, 2.5V, 1.8V depending on the I/O standard selected per pin. Decouple each VCCINT/VCCIO pin with a 0.1uF ceramic capacitor placed within 5mm of the pin, plus bulk decoupling at the regulator output. Power sequencing: VCCINT must reach 90% of nominal before VCCIO exceeds 1.0V to avoid I/O latchup.
The exposed thermal pad on the 208-RQFP must be soldered to a grounded copper pour of at least 1 square inch to dissipate 1-2W typical operating power. Without proper thermal pad soldering, junction temperature may exceed 125C in industrial environments, triggering thermal shutdown or long-term reliability degradation. Use 8 thermal vias (0.3mm drill) under the pad to inner ground planes for optimal heat spreading.
Configuration pins MSEL0/MSEL1 select the configuration mode - wrong settings cause the device to fail to configure or configure incorrectly from the wrong source. nCONFIG must be held low during power-up and released only after VCCINT and VCCIO are stable. For passive serial configuration, an EPC2 or EPC16 configuration EPROM is required. JTAG chain integrity (TCK pull-up, TMS pull-up, TDI pull-up) is mandatory for in-system programming.
Route clock signals on inner layers with controlled impedance (50 ohm microstrip or stripline) and keep clock traces short to minimize skew. The EP20K200 has dedicated clock input pins with PLL capability - place clock drivers close to these pins. Separate analog/digital grounds if the design mixes analog I/O standards; connect at a single star point near the FPGA ground pin.
