EP2C8T144C7N - Cyclone II FPGA, 8K LEs, 144-LQFP | Intel
MPN: EP2C8T144C7N ⚠ Lần mua cuốiEP2C8T144C7N Tóm tắt
An FPGA (Field-Programmable Gate Array) is a programmable logic device that sits in the broader hierarchy: programmable logic -> logic IC -> integrated circuit -> semiconductor. Cyclone II is Intel/Altera's cost-optimized family targeting high-volume, power-sensitive applications such as consumer, industrial control, and display bridges, sitting below the higher-performance Stratix family in the same generation.
Key features include 8,256 logic elements, 36 embedded 18x18 multipliers, 165,888 RAM bits organized as M4K blocks, 2 PLLs for clock synthesis, 85 user I/Os with LVDS support, and a 1.2 V core supply with hot-socketing capability. The part suffix C7 indicates the commercial speed grade (7) and N indicates lead-free. The LQFP-144 package is a plastic surface-mount body of 20x20 mm with 0.5 mm pitch, making it friendly for low-cost 4-layer PCB assembly.
The Cyclone II architecture uses a 2-D row/column routing fabric driven by LABs (Logic Array Blocks), with each LAB containing 16 logic elements. M4K RAM blocks can be configured as true dual-port, simple dual-port, or single-port memory, supporting FIFO, shift register, and ROM modes. DSP blocks implement 18x18 multipliers with optional add/sub pipeline stages, enabling efficient DSP filtering without consuming general-purpose logic.
Typical applications include video processing bridges (HDMI/CSI-to-LVDS), motor control and industrial automation glue logic, LED display controllers, low-end software-defined radio front ends, and legacy glue-logic consolidation. The 85 I/Os and modest logic capacity make it well-suited to bridge between parallel buses and high-speed serial links.
When designing with this device, use the Quartus II Web Edition toolchain (legacy) or a compatible third-party toolchain, and respect the 1.2 V core voltage sequencing requirement. Decouple each VCCINT/VCCIO bank with 100 nF and 10 uF capacitors placed within 5 mm of each power pin.

Ứng dụng tiêu biểu
EP2C8T144C7N phù hợp cho 6 Áp dụngs: Video Bridge / Display Controller, Industrial Motor Control & PLC Glue Logic, LED Display Panel Controller, Legacy Parallel-Bus to Memory Bridge, Low-End Software Defined Radio (SDR) Front End, Educational & FPGA Development Platforms.
Video Bridge / Display Controller
The EP2C8T144C7N's 85 user I/Os and dedicated hardware multipliers make it a strong fit for video bridge applications such as HDMI-to-LVDS, MIPI-CSI-to-TTL, or BT.656 frame-combiner designs. With 36 embedded 18x18 multipliers the part can perform real-time chroma resampling and deinterlacing at common 480p/720p rates without consuming general-purpose logic, while the M4K RAM blocks implement line buffers and chroma FIFOs. The 144-LQFP 0.5 mm pitch package is friendly to 4-layer low-cost PCB assembly used in displays and TV front-end boards.

Industrial Motor Control & PLC Glue Logic
With 2 PLLs, 36 multipliers, and 85 LVDS-capable I/Os, the EP2C8T144C7N can implement field-oriented control (FOC) for 3-phase brushless DC and AC induction motors, encoding quadrature counters, PWM generators, and CAN/RS-485 bridges in a single chip. The hardware 18x18 multipliers accelerate Park/Clarke transforms while M4K blocks buffer sensor data; the industrial -40C to +85C operating range supports factory-floor deployment. The LQFP-144 package withstands vibration better than BGA, important for motor-drive PCB assemblies.
Được đề xuất
LED Display Panel Controller
LED display panels for outdoor signage require high refresh rates, gamma correction, and large parallel data buses - the EP2C8T144C7N's 85 user I/Os drive 10+ parallel RGB data channels plus addressing, while M4K RAM blocks implement per-pixel gamma LUTs and refresh buffers. The 2 PLLs synthesize pixel clocks from any reference and 36 multipliers accelerate brightness/contrast pipelining. At 90-nm process the part delivers this performance at well under 1 W typical, important for sealed outdoor enclosures with limited thermal dissipation.
Được đề xuất
Legacy Parallel-Bus to Memory Bridge
Many embedded designs still use 8/16-bit SRAM, NOR flash, or 68k-style parallel buses that newer microcontrollers no longer support. The EP2C8T144C7N bridges these legacy interfaces to modern SDRAM/DDR or SPI flash with its 85 I/Os and 165 Kbit of M4K RAM acting as bus turnaround buffers. The hardware multipliers and DSP blocks are unused in this role but provide headroom for on-the-fly CRC/checksum computation. The 144-LQFP and 0.5 mm pitch keeps PCB routing straightforward for retro-upgrades of legacy systems.
Được đề xuất
Low-End Software Defined Radio (SDR) Front End
The 36 hardware 18x18 multipliers in the EP2C8T144C7N implement up to 9 complex FIR filters or 18 real FIR taps per clock at typical audio-band sample rates, supporting simple IF-band SDR front ends and DDC/DUC blocks. The 2 PLLs lock to a low-jitter reference oscillator and 85 I/Os interface to dual-channel ADC/DAC pairs. Cyclone II lacks high-speed serial transceivers, so this use case is limited to baseband or low-IF designs, but the part delivers adequate DSP horsepower for HF/AM/FM demodulation and experimental narrowband SDR projects.
Được đề xuất
Educational & FPGA Development Platforms
The EP2C8T144C7N's moderate 8,256-LE capacity, on-chip PLLs, multipliers, and 144-LQFP-friendly 0.5 mm pitch make it a popular choice for university FPGA teaching boards, hobbyist projects, and entry-level Altera/Intel development kits. Quartus II Web Edition (free legacy toolchain) supports the device, and the T144 package can be hand-soldered or socketed on a through-hole adapter for breadboard experimentation. The Cyclone II architecture is well documented in textbooks and online labs, making it ideal for learning VHDL/Verilog on real silicon.

Ghi chú thiết kế
The EP2C8T144C7N requires a monotonic 1.2 V ramp on every VCCINT pin with 100 nF and 10 uF decoupling placed within 5 mm of each pin. Per the Cyclone II handbook, all eight VCCIO banks must be powered even if unused (tie to a valid rail) to prevent I/O buffer latch-up. A dedicated LDO such as an LT3080-1 or TPS7A4533 should feed VCCINT; do not share the 1.2 V rail with digital ICs because inrush can pull VIN below the 1.15 V minimum and cause configuration failure.
Route all 144 LQFP traces on a 4-layer stack-up with continuous ground plane under the device. Per the Cyclone II package guidelines, decouple each VCCIO bank with a 0.1 uF X7R plus a 10 uF bulk capacitor placed within 5 mm of the bank pin. JTAG chain signals (TCK, TMS, TDI, TDO) must be length-matched to within 25 mm to avoid programming failures; route TCK with a 33 ohm series termination if the JTAG header is more than 50 mm from the FPGA.
LVDS operation on the EP2C8T144C7N requires 100-ohm differential impedance and matched trace lengths within 150 mils. Per the Cyclone II device handbook, place LVDS pairs on the same VCCIO bank and avoid routing over plane splits. For SDRAM interfaces above 100 MHz, route clocks on the inner layers with continuous GND reference and place series termination resistors within 5 mm of the FPGA pin to control overshoot.
Do not leave CONFIG_DONE, nCONFIG, or nSTATUS floating - the Cyclone II handbook requires these to be tied to VCCIO via 10 kohm pull-ups. An unlatched nCONFIG or floating nSTATUS can prevent configuration at power-on and the device will appear 'dead'. Always include a debounced manual nCONFIG pushbutton and an AS configuration mode header so you can recover from corrupted bitstream without reworking the board.
