EPF10K20RC208-3 概要
An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit whose logic function is defined after manufacture by the end user. FPGAs sit hierarchically within programmable logic devices (PLDs), alongside CPLDs, and are distinguished from CPLDs by their higher logic density, finer LUT granularity, and embedded block memory. The FLEX 10K family was Altera's first device family to integrate embedded array blocks (EABs) of SRAM memory alongside the logic array, creating a system-on-a-programmable-chip (SOPC) platform.
Key features of the EPF10K20RC208-3 include 144 Logic Array Blocks (LABs) each containing 8 Logic Elements, configurable I/O standards supporting 5V TTL/CMOS interfaces, an in-system programmability (ISP) interface via the serial configuration EPROM, and built-in JTAG boundary-scan test (IEEE 1149.1 BST) support. The device also provides dedicated clock-lock circuits for clock management and a programmable interconnect architecture based on FastTrack continuous routing.
Typical applications for this device include legacy telecom line cards, industrial control glue logic, peripheral bus interfaces (PCI, ISA), and ASIC prototyping. Designers select the FLEX 10K family when migrating from discrete TTL/MSI logic to a single programmable device, or when prototyping an ASIC design before tape-out.
When designing with this part, ensure 5.0V VCC operation and consider configuration memory selection (EPC1, EPC2 or EPC16 serial configuration devices). Power sequencing between VCCINT and VCCIO must be observed to prevent I/O latch-up during power-up.

主な用途
EPF10K20RC208-3 の用途: 6 件s: Legacy Telecom Line Card Interface, Industrial PLC Glue Logic Replacement, ASIC Prototyping Platform, PCI/ISA Bus Interface Bridge, Flat-Panel Display Controller, Test & Measurement Instrumentation Front-End.
Legacy Telecom Line Card Interface
The EPF10K20RC208-3 fits legacy telecom line card interface designs that require 5V TTL-compatible I/O and moderate logic density in a single programmable device. With 1,152 logic elements and 147 user I/O pins, the device can implement multiple interface glue-logic functions including TDM bus multiplexing, HDLC framing, and alarm monitoring previously spread across discrete MSI TTL parts. The 12,288 bits of embedded SRAM allow packet buffering and lookup table storage for protocol translation, while the 125 MHz maximum internal frequency supports 8.192 Mbps E1/T1 data rates with significant timing margin.
おすすめ
Industrial PLC Glue Logic Replacement
The EPF10K20RC208-3 is well-suited to industrial PLC designs where it replaces dozens of discrete 74-series TTL/MSI logic packages with a single programmable device, reducing PCB area and improving reliability. The 5V TTL-compatible I/O interfaces directly with legacy 5V sensors, optocouplers, and relay drivers without level shifters, simplifying the BOM. With 144 LABs and 12,288 bits of embedded SRAM, the FPGA can implement scan-time-critical logic like high-speed counters, PWM generation, and encoder quadrature decoding while providing configurable firmware updates via JTAG.
おすすめ
ASIC Prototyping Platform
The EPF10K20RC208-3 serves as a cost-effective ASIC prototyping vehicle for designs targeting 20K to 50K gate ASICs, allowing pre-silicon functional verification on real hardware. Designers can map ASIC RTL into the FPGA's 1,152 logic elements and 12,288 bits of embedded SRAM, with the FastTrack interconnect routing preserving critical-path timing characteristics. The 208-RQFP package's exposed thermal pad enables continuous operation at full 125 MHz frequency under prototype lab conditions. Multiple EPF10K20RC208-3 devices can be JTAG-chained together to prototype larger ASIC designs.
おすすめ
PCI/ISA Bus Interface Bridge
The EPF10K20RC208-3 is suitable for PCI or ISA peripheral card designs requiring a custom bus bridge or interface controller, with its 147 user I/O pins directly accommodating 32-bit PCI plus side-band signals. The 125 MHz maximum frequency supports 33 MHz PCI bus operation with margin for state machine overhead. Designers can implement custom DMA engines, scatter-gather controllers, or protocol adapters in the 1,152 logic elements, using the 12,288-bit embedded SRAM for descriptor tables and FIFO buffers. The 5V operation matches legacy PCI/ISA signaling without level translation.
おすすめ
Flat-Panel Display Controller
The EPF10K20RC208-3 can implement flat-panel display timing controllers and LVDS data serializers for industrial monitor and medical imaging applications. Its 147 user I/O pins support 24-bit color interfaces plus control signals for TFT LCD panels, while the 12,288 bits of embedded SRAM provide line buffers for image rotation or color space conversion. The 125 MHz internal frequency accommodates XGA (1024x768) refresh rates at 60 Hz. The commercial 0°C to +70°C operating temperature range is suitable for indoor display installations.
おすすめ
Test & Measurement Instrumentation Front-End
The EPF10K20RC208-3 is appropriate for bench-top test equipment digital front-ends, including custom stimulus generation, protocol-aware triggering, and timing-critical capture logic. Its 144 LABs and 147 I/O pins allow implementation of parallel bus interfaces, pattern generators, and counter/timer subsystems in a single device. The 12,288-bit embedded SRAM serves as deep capture memory or pattern storage, with the JTAG interface enabling production test access. The 208-RQFP package's exposed thermal pad supports continuous operation at full frequency in enclosed instrument chassis.

設計ノート
The EPF10K20RC208-3 requires a stable 5.0V VCCINT supply and 5.0V VCCIO supply. Decoupling: place one 0.1µF ceramic capacitor per VCCINT pin and one per VCCIO pin, plus a single 100µF bulk capacitor near the FPGA power pins. Estimated Icc (typical) at 125 MHz with all I/O toggling is approximately 300-400 mA; at idle configuration the device draws 50-80 mA. Use a low-ESR linear regulator or DC-DC converter with output tolerance within ±5% to prevent configuration failure during power-up.
The 208-RQFP package has a 0.5 mm pitch and 30.6 mm × 30.6 mm body size with an exposed thermal pad on the bottom. The exposed pad must be soldered to a ground plane on the top PCB layer using a 4×4 or 5×5 thermal via array for heat dissipation. Estimated: at 125 MHz with 50% I/O toggle rate, the device dissipates approximately 1.5-2.0 W and the exposed pad reduces theta-JA by ~30%. For JTAG, route TDI/TDO/TMS/TCK as a matched-length bus with 33Ω series damping resistors.
Configuration failure modes: (1) VCCINT must reach 4.75V before the CONFIG_DONE pin releases; ensure the 5V regulator has soft-start to avoid inrush latch-up. (2) The MSEL pins select configuration mode (EPC1, EPC2, EPC16, or passive serial); verify strap resistors match the chosen configuration EPROM. (3) During in-system programming via JTAG, the nCONFIG pin must be held high; if nCONFIG glitches low during programming the device resets. (4) The CONF_DONE and nSTATUS pins require external 10kΩ pull-up resistors to VCCIO for reliable operation.
Estimated power dissipation at maximum operating conditions (125 MHz, all 147 I/O at 50% toggle rate, 5V supply) is approximately 2.0 W. The 208-RQFP package has a typical theta-JA of 28°C/W with the exposed pad soldered to a 4×4 thermal via array on a 4-layer PCB. Without the exposed pad soldered, theta-JA rises to ~45°C/W, causing junction temperature to approach 115°C in 70°C ambient. Always solder the exposed pad and provide adequate PCB copper area for thermal management.
