EP20K200RI240-2V 개요
An FPGA is a semiconductor device containing programmable logic blocks and interconnect that can be configured after manufacturing to implement digital systems. In the APEX 20K architecture, look-up table (LUT) logic, product-term logic, and embedded memory are combined, so control logic, datapath functions, and memory resources can be integrated on a single programmable device. This places the part in the programmable logic hierarchy of FPGA -> programmable logic device -> semiconductor, between simple CPLDs and large contemporary FPGAs.
Key features of the EP20K200RI240-2V are its 200K-gate capacity, 8,320 logic cells, 174 user I/O lines, 2.5/3.3 V I/O capability, and 0.22 um process. Distributor listings specify 200 MHz maximum clock speed for the family/order code, while Microchip USA records a 160 MHz figure for this package and temperature variant. The 240-pin 0.5 mm-pitch RQFP package supports surface-mount assembly and moderate-density board layouts.
The architecture includes embedded memory blocks and MultiCore LUT-plus-product-term logic, enabling designs that blend state machines, arithmetic datapaths, and memory. The I/O supports LVTTL/LVCMOS-style interfaces at 2.5 V or 3.3 V, depending on the VCCIO bank setting. Because this is an industrial-suffix part, it is intended for environments requiring wider operating temperature range than commercial -C alternatives.
Typical applications include legacy industrial controller repairs, telecom infrastructure glue logic, custom test equipment, and retrofit of APEX 20K-based boards where no direct pin-compatible newer FPGA exists. Its large I/O count and block memory make it suitable for bus interfacing, video capture preprocessing, and medium-density control functions.
A key design consideration is that this is an obsolete part with no verified direct replacement in newer Intel/Altera families. Keep the 2.5 V core separate from the I/O supply, verify pin compatibility against the original datasheet before substituting a 240-RQFP sibling, and plan a last-time buy if production must continue.
This page assembles distributor availability, package details, cross-reference caveats, and maintenance-oriented design guidance that are not all present in a single manufacturer datasheet, helping engineers keep legacy systems alive with verified parametric grounding.

Legacy Industrial Controller Replacement and Repair
For PLCs, motion controllers, and process instruments originally built around APEX 20K, the EP20K200RI240-2V provides 174 user I/O and 200K gates in the original 240-pin RQFP footprint, allowing continued production without PCB re-spin. The I-suffix industrial screening suits factory-floor ambients, and 2.5/3.3 V I/O banking permits direct 3.3 V bus interface. Because Intel/Altera no longer offers a direct pin-compatible new family replacement, the only low-risk repair path is to source the exact APEX 20K variant, verify the datasheet thermal limits, and program spares. This application maximizes board reuse and minimizes re-qualification effort for installed systems.

Telecom Line-Card Bridge and Glue Logic
The EP20K200RI240-2V works well in telecom line-card bridging where a design needs moderate gate density, multiple bus interfaces, and deterministic programming. Its 200K gates and 8,320 cells can absorb address decoding, FIFO-control state machines, and status register logic that would otherwise consume multiple CPLDs. With 2.5/3.3 V I/O, it connects directly to 3.3 V framers, PHYs, and microprocessors commonly used in legacy telecom equipment. The 240-pin 0.5 mm pitch package fits compact boards, while the industrial suffix supports central-office temperature variations. Applications should plan for EPC2/EPC16 configuration memory and a JTAG programming header.
추천
Wireless Base-Station Control and Monitoring
In legacy wireless base stations, the EP20K200RI240-2V can implement control-plane monitoring, alarm aggregation, and backplane handshaking without adding a processor. The MultiCore LUT and product-term blocks allow mixed register-heavy and combinatorial functions to coexist in one device. Its 174 I/O lines support parallel monitoring buses, while 2.5 V core operation reduces power relative to older 5 V parts. The industrial I-suffix is suited to outdoor telecom cabinets. For retrofit, maintain original Quartus configuration files and use a JTAG boundary-scan chain during board test. Since this is an APEX 20K-era part, no new pin-compatible family should be assumed.
추천
Video and Image Frame Capture Preprocessing
The EP20K200RI240-2V can serve as a frame-capture preprocessing FPGA in industrial inspection systems, receiving pixel data, performing simple line buffering and windowing, and passing formatted data to a DSP or host processor. Its embedded memory blocks reduce external FIFO requirements, and 174 general-purpose I/O pins can connect to CMOS imagers, SRAM, and processors. The 2.5/3.3 V I/O levels simplify interfacing to 3.3 V video converters and memories. The 200K-gate capacity is sufficient for pixel counters, timing generators, and small kernels, though demanding image filters may require a larger device. For legacy repairs, the -2V suffix provides availability matching existing board specifications.
추천
Custom Test and Measurement Instrumentation
Test and measurement customers building high-channel-count data acquisition and pattern generators can use the EP20K200RI240-2V as a digital control and sequencing engine. Its 8320 logic cells can implement acquisition state machines, trigger logic, and counter/timer blocks, while 174 I/O lines connect to ADCs, DACs, comparators, and front-panel buses. The deterministic APEX 20K architecture and JTAG configuration allow in-system updates during calibration. For a standalone instrument, 2.5 V core with 3.3 V I/O is compatible with common converter logic. The obsolete status means program spares should be purchased with the FPGA stock, and original JEDEC/POF files should be preserved for configuration memory.
추천
Aerospace and Defense System Retrofit
The EP20K200RI240-2V can support retrofit of avionics or defense electronics where an original APEX 20K RQFP design must be reproduced without redesign. The industrial I-suffix is preferred over commercial RC variants when equipment may be exposed to non-laboratory environments, but the exact military/aerospace qualification is not specified by the data. Engineers should confirm the component is acceptable for their environmental and reliability requirements before installation. The 2.5 V core and 3.3 V I/O levels are compatible with legacy military interface logic. Because the part is obsolete, a rigorous last-time-buy, traceability review, and incoming inspection plan is mandatory for mission-critical retrofits.

설계 노트
Use a PCB stackup with a clean 2.5 V core plane and separate 2.5 V or 3.3 V I/O plane islands for the VCCIO banks. Decouple each FPGA supply pin group with low-ESR ceramic capacitors and add bulk tantalum/ceramic capacitance near the package edge. For the 240-pin RQFP, avoid placing vias under the body that could interfere with solder inspection; use solid ground pour beneath the device. Because the exact APEX 20K pin map was not reproduced in the snippet data, obtain the family datasheet and confirm every VCC/GND pin before layout.
A 240-pin RQFP package dissipates heat primarily through the gull-wing leads and board copper, so a thermal relief to an inner ground plane improves heat spreading. No thermal resistance value is shown in the current web snippets; estimate power using the Intel/Altera power calculator for the routed design, then calculate junction temperature using the datasheet theta-JA and actual ambient. If the estimate exceeds the operating limit near industrial maximum, add forced airflow or reduce I/O drive strength. Always label such calculations as estimates until the official thermal model is used.
Do not assume that a newer Cyclone IV or Cyclone 10 FPGA is drop-in compatible with EP20K200RI240-2V; Intel/Altera community guidance explicitly says the newer families come in different packages and need PCB and power supply changes. Within the APEX 20K family, a 240-pin RQFP sibling may have a different temperature grade or speed bin, but pin-for-pin compatibility still must be verified from the reliable APEX 20K pin table. Also preserve Quartus project files, POF/SOF configuration files, and JTAG chain details before redistributing remaining stock.
With 0.5 mm-pitch QFP leads and up to 174 user I/O lines switching concurrently, simultaneous switching output noise can be significant. Place series resistors near the FPGA outputs for long traces, keep each traced signal over a continuous reference plane, and set I/O slew-rate/current options in the fitter according to the load. Use 47 ohm to 100 ohm series resistors on high-speed unidirectional signals and avoid routing long parallel buses too closely. When possible, assign clock and control pins to dedicated inputs and clock-capable pins rather than general I/O.
규정 준수 정보
No RoHS, REACH, AEC-Q100, or material compliance statement was present in the verified web snippets for EP20K200RI240-2V. The N suffix on some sibling parts may indicate lead-free finish, but the target -V suffix is not documented as a compliance mark. Obtain a certificate of compliance from the supplier before use in regulatory-constrained products.
