EP2C5T144C7N 概述
A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit whose logic function is defined by the customer after manufacture, providing a parallel fabric of configurable logic blocks (CLBs), routing interconnect, dedicated memory blocks (M4K/M9K in Cyclone II), DSP/multiplier blocks, clock management tiles (PLLs), and programmable I/O cells (IOEs). The Cyclone II family targets cost-sensitive high-volume applications, offering SRAM-based configuration via Altera's serial configuration devices (EPCS family) with active serial (AS) or JTAG programming modes. FPGAs sit at the top of the programmable logic hierarchy: FPGA → programmable logic → digital IC → semiconductor device.
Key features of the EP2C5T144C7N include up to 89 user I/Os in the LQFP-144 footprint, 4,608 logic elements for moderate-complexity state machines and datapaths, dedicated 18 × 18 multiplier blocks for DSP-style fixed-point arithmetic, two PLLs for clock synthesis and skew management, support for common I/O standards including LVTTL, LVCMOS, PCI, SSTL-2, and differential LVDS pairs, and 119,808 bits of on-chip RAM distributed across M4K blocks. The part ships in a 144-LQFP package with 20 × 20 mm body, 0.5 mm pitch, surface-mount compatible.
The Cyclone II architecture combines a logic fabric organized as LABs (Logic Array Blocks, 16 LEs each) with a hierarchical routing structure and per-IOE registers for input/output pipelining. Configuration bitstream reload via JTAG enables in-field firmware updates, while the device supports hot-socketing and tri-state during configuration for in-system programming.
Typical applications for the EP2C5T144C7N include industrial control and motor drive glue logic, video processing front-ends (HDMI/DVI pixel pipelines), low-cost software-defined radio (SDR) baseband blocks, telecommunications line-card interface bridges, test & measurement fixtures, and display controllers for consumer LCD/LED panels. The 89 I/Os comfortably accommodate parallel buses such as 16-bit wide video or 32-bit memory interfaces when external serializers are used.
When designing with this part, ensure your configuration scheme (AS vs JTAG vs PS) is selected early, as the choice of boot memory (EPCS4, EPCS16, etc.) determines board cost. Decoupling follows Altera's PDN guidance: bulk 100 µF + 10 µF + 0.1 µF per supply rail. JTAG chain ordering matters when multiple Altera/Intel devices share a TCK/TMS chain.

典型应用
EP2C5T144C7N 适用于 6 应用s: Industrial Motor Control & Drive Logic, Video Processing Front-End & Display Controller, Telecom Line-Card Interface Bridge, Low-Cost Software-Defined Radio (SDR) Baseband, Test & Measurement Fixture / Instrument Front-End, Consumer LCD/LED Display Controller.
Industrial Motor Control & Drive Logic
The EP2C5T144C7N fits industrial motor drive designs thanks to its 89 LVTTL/LVCMOS-capable I/Os that can simultaneously drive PWM generator outputs, encoder feedback inputs, and isolated SPI comms. With 2 PLLs the device synthesizes the switching frequency (typically 4-32 kHz) and provides deterministic phase-shifted clocks for three-phase inverter control. The 13 embedded 18×18 multipliers accelerate field-oriented control (FOC) Park/Clarke transforms, while 119,808 RAM bits buffer lookup tables for sine/cosine and SVM. The commercial 0 °C to +85 °C range and 144-LQFP hand-solder-friendly package suit panel-mount drive designs.
推荐
Video Processing Front-End & Display Controller
For SD/HD video pipelines, the EP2C5T144C7N's 4,608 LEs and 119,808 RAM bits (26 M4K blocks) implement a video input formatter, deinterlacer, or color-space converter. The 89 I/Os comfortably accept a 16-bit wide ITU-R BT.656 bus plus control signals and output a 24-bit RGB TTL panel interface. Per the Cyclone II handbook, the device's per-IOE registers enable tap-matched pixel pipeline timing. The 2 PLLs synthesize pixel clocks (e.g., 27 MHz for SD, 74.25 MHz for 720p) from a single reference. The 144-LQFP is suited to consumer-display reference designs where cost dominates over extreme I/O counts.
推荐
Telecom Line-Card Interface Bridge
Telecom line cards use the EP2C5T144C7N to bridge legacy TDM (T1/E1) framers to modern packet backplanes. Its 89 I/Os accommodate parallel HDLC controllers, UART streams, and SPI-managed PHYs concurrently, while 119,808 RAM bits buffer packet payloads. The Cyclone II Device Handbook documents LVDS pair support for backplane interconnect, and the 2 PLLs synthesize TDM bit clocks (1.544/2.048 MHz) from a 19.44 MHz system reference. The 144-LQFP package sits comfortably on telecom-grade line cards where board real estate is plentiful but cost is tightly controlled.
推荐
Low-Cost Software-Defined Radio (SDR) Baseband
Entry-level SDR baseband designs leverage the EP2C5T144C7N's 13 dedicated 18×18 hardware multipliers to perform fixed-point FFT/FIR filtering at IF sample rates up to ~30 MSPS. Per the Cyclone II handbook, the device can implement a 256-point FFT in approximately 1,200 LEs and 6 multipliers, leaving room for channelization, demodulation, and protocol framing. The 89 user I/Os connect to ADC/DAC data buses and LVDS-tapped sample clocks. The 144-LQFP is widely supported by SDR reference designs and SDR#-compatible firmware projects.
推荐
Test & Measurement Fixture / Instrument Front-End
Automated test equipment (ATE) and bench instruments use the EP2C5T144C7N as a glue-logic aggregator between mixed-signal front-ends, ADCs, and a host PC. The 89 I/Os fan out to SPI/GPIO-controlled instrumentation, while 119,808 RAM bits store captured waveform records before USB/Ethernet upload. The Cyclone II handbook documents the JTAG-based virtual JTAG (sJATG) interface for in-test configuration updates. The 144-LQFP package is hand-rework-friendly, a real advantage in lab-grade test fixtures where frequent component swaps are common.
推荐
Consumer LCD/LED Display Controller
Consumer flat-panel displays (TVs, monitors, digital signage) use the EP2C5T144C7N as the main timing controller and on-screen display (OSD) engine. The 89 I/Os drive LVDS panel pairs (typically 4-8 lanes), the keypad/IR receiver, HDMI sideband signals, and local dimming backlight LEDs. Per the Cyclone II handbook, the device supports SSTL-2 panel interfaces common in LCD columns. The 2 PLLs synthesize pixel clocks up to 165 MHz for 1080p. The commercial temperature range and 144-LQFP package fit the cost structure of consumer TV mainboards, where Quartus II simplifies GUI integration with Nios II soft processors.

设计说明
The Cyclone II Device Handbook specifies the EP2C5 core supply (VCCINT) at 1.15-1.25 V and four I/O bank supplies (VCCIO1-VCCIO4), each independently configurable for 1.5/1.8/2.5/3.3 V. Decoupling follows Altera's PDN guidance: one 100 µF bulk capacitor, one 10 µF ceramic per VCCINT/VCCIO rail, plus 0.1 µF high-frequency bypass placed within 5 mm of each supply pin pair. Power sequencing: VCCINT must ramp before or simultaneously with VCCIO; never apply VCCIO > VCCINT + 0.7 V or device damage may occur. Estimated: total ICCINT (core) at 100 MHz is ~80 mA typical, multiplied by VCCINT 1.2 V = 96 mW static power.
Per the Cyclone II Device Handbook, the 144-LQFP package requires 0.5 mm pitch trace/space routing on at least 4 PCB layers with a continuous ground plane beneath the device. Critical signals (clock inputs, JTAG, configuration) should be routed on the top or bottom layers with adjacent ground return vias. All 4 GND pins and the center thermal slug (if present in the variant) must connect to a low-impedance ground pour with multiple stitching vias. Length-match differential pairs (LVDS) within 0.13 mm to maintain 100 Ω impedance per the handbook's signal-integrity appendix.
Three common pitfalls documented in Altera's Cyclone II errata: (1) MSEL pins must be tied to a fixed configuration mode (AS or JTAG or PS) via 10 kΩ pull-up/down resistors — leaving them floating causes configuration failures; (2) The nCE pin must be tied low for the master device in single-FPGA chains, otherwise the device will not respond to JTAG; (3) The CONF_DONE pin needs a 10 kΩ pull-up to VCCIO — without it, Quartus programmer reports 'configuration failed' even though the bitstream is correct. Reference: Cyclone II Device Handbook Chapter 11 (Configuration).
The 144-LQFP package has a typical θJA of approximately 30-35 °C/W on a 4-layer JEDEC test board. Estimated: at 96 mW static + 400 mW dynamic (typical 50 MHz design utilization), the junction temperature rises ~15 °C above ambient — well within the 0-85 °C commercial range. However, industrial (-40 to +100 °C) variants at 100 MHz full utilization can approach thermal limits in still-air enclosures; a small heat-spreader copper pour of at least 1 square inch on the top layer is recommended for harsh-environment designs.
