EP1C6T144C7N 概覽
The Altera (Intel) EP1C6T144C7N is a Cyclone-series Field Programmable Gate Array (FPGA) with 5980 logic cells, 92160 bits of embedded SRAM, and 98 user I/Os, housed in a 144-pin TQFP (Thin Quad Flat Pack) package measuring 22x22 mm with 0.5 mm pitch. The device is fabricated on a 1.5V CMOS process and operates at a maximum internal frequency of approximately 320 MHz, making it well suited for cost-sensitive digital logic, glue logic, and parallel processing applications.
A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells. Unlike an ASIC, an FPGA's function is defined by a user-supplied bitstream loaded into on-chip SRAM configuration memory. The Cyclone family occupies the low-cost, high-volume segment of the FPGA hierarchy (FPGA -> programmable logic -> programmable logic device -> semiconductor) and is commonly used as a bridge between discrete logic and higher-density FPGAs such as Stratix.
Key features of the EP1C6T144C7N include 5980 logic elements, 5980 CLBs (equivalent to 1 logic array block per 10 LEs), 20 M4K RAM blocks providing 92160 bits of embedded memory, two PLLs for clock management, and LVTTL/LVCMOS/PCI I/O support with hot-socketing capability. The device supports configuration via passive serial (PS), active serial (AS), and JTAG modes, and offers low-power operation compared to earlier SRAM FPGAs. The TQFP-144 package is lead-free and RoHS compliant.
Architecturally, the EP1C6T144C7N is built on a 130 nm SRAM-based CMOS process with a Look-Up Table (LUT)-based logic fabric and a hierarchical interconnect routing architecture. Each Logic Element (LE) contains a 4-input LUT, a programmable register, and carry chain logic for arithmetic functions. The M4K memory blocks can be configured as RAM, ROM, or FIFO and support true dual-port operation, enabling efficient data buffering in DSP and communications pipelines.
Typical applications include digital signal processing front-ends, industrial control and motor control logic, telecommunications interface bridges, video processing pipelines, prototype ASIC emulation, and embedded coprocessors in microcontroller-plus-FPGA designs. The combination of moderate logic density, abundant I/O, and low unit cost also makes it attractive for educational platforms and low-volume production.
When designing with the EP1C6T144C7N, ensure clean 1.5V core and 3.3V I/O power rail decoupling, with multiple bulk and high-frequency ceramic capacitors placed close to the package pins. Use the Altera Quartus II design suite for synthesis, place-and-route, and bitstream generation. Verify JTAG chain integrity before attempting configuration and observe the device's configuration setup and hold timing for the chosen mode.

What is the EP1C6T144C7N and what series does it belong to?
The EP1C6T144C7N is a Cyclone-series Field Programmable Gate Array (FPGA) from Altera (now Intel) with 5980 logic elements and 98 user I/Os. According to Altera's Cyclone Device Handbook, it is part of the Cyclone I family, the company's first low-cost SRAM-based FPGA line introduced at 130 nm on a 1.5V core process, targeting high-volume digital logic applications.
How many logic elements, RAM bits, and I/Os does the EP1C6T144C7N have?
The EP1C6T144C7N delivers 5980 logic elements, 92160 bits of embedded SRAM organized in twenty M4K blocks, and 98 user I/Os. These figures match the values published in the Cyclone I family datasheet and confirm the device's positioning as a mid-density member of the original Cyclone line, above the EP1C3 and below the EP1C12 and EP1C20 siblings.
What is the maximum operating frequency of the EP1C6T144C7N?

Because the part is mature and active, lead times are short, but buyers should verify factory-traceable stock for new designs to avoid counterfeit risk.
EP1C6T144C7N vs EP1C6T144C6N - which speed grade should I choose?
The EP1C6T144C7N is the C7 (faster) speed grade while the EP1C6T144C6N is the C6 (slower) speed grade of the same device. Both share the same 5980 LEs, 92160 RAM bits, 144-TQFP package, and 1.5V core. Choose C7 when timing closure is tight or fMAX matters; choose C6 to reduce cost when your design comfortably meets timing at the slower grade.
EP1C6T144C7N vs EP1C12 - which Cyclone I should I use?
The EP1C6T144C7N offers 5980 logic elements and 98 I/Os, while the EP1C12 family doubles that to roughly 12060 LEs with more RAM and I/Os. For designs that comfortably fit within 5980 LEs, the EP1C6 is the lower-cost and more readily available option. Move to EP1C12 when your logic, block RAM, or I/O budget exceeds the EP1C6 envelope.
When should I choose EP1C6T144C7N over a Cyclone II or Cyclone III device?
Choose the EP1C6T144C7N when you need a mature, low-cost Cyclone I device for designs that are already implemented and verified on this part, or when second-source continuity matters more than modern features. Migrate to Cyclone II (EP2C) or Cyclone III (EP3C) only if you need higher logic density, more RAM, lower core voltage (1.2V), or embedded multipliers - those migrations require a full re-design because packages and pinouts differ.
What is the best drop-in replacement for the EP1C6T144C7N?
The best drop-in replacement for the EP1C6T144C7N is the EP1C6T144C8N (C8 speed grade, identical 144-TQFP footprint, same 5980 LEs and 98 I/Os). The C8 is the next-faster speed grade and is pin-to-pin compatible, allowing a direct PCB swap. Other valid same-package alternatives include the EP1C6T144C6N (slower grade) and the EP1C6Q240C7N (different package, not a drop-in).
Can EP1C6Q240I7N replace the EP1C6T144C7N on my existing board?
No, the EP1C6Q240I7N is NOT a drop-in replacement for the EP1C6T144C7N. Although both are Cyclone I devices with the same 5980 logic elements, the EP1C6Q240I7N is housed in a 240-pin QFP package and uses an industrial temperature grade. The larger package and different pin assignment mean a board redesign is required for any Q240-to-T144 migration.
Where can I download the EP1C6T144C7N datasheet PDF?
The official EP1C6T144C7N datasheet is bundled inside the Altera Cyclone Device Handbook, available from the Intel FPGA documentation center at www.altera.com. The handbook covers the entire Cyclone I family including pinouts, timing models, electrical characteristics, and configuration schemes. Distributors such as DigiKey and Mouser also host PDFs linked from the EP1C6T144C7N product page.
Where do I find the EP1C6T144C7N pinout for the 144-TQFP package?
The pinout for the EP1C6T144C7N's 144-TQFP package is published in the Cyclone Device Handbook pin-out tables, where T144 variants of the EP1C6 are mapped to specific ball/pin functions, including dedicated clock inputs, JTAG pins, and configuration pins. The same tables list power and ground pins; refer to the EP1C6T144 dedicated-pin section to confirm the orientation before routing the PCB.
What are the key specifications of EP1C6T144C7N that engineers should know?
The EP1C6T144C7N delivers 5980 logic elements, 92160 bits of embedded RAM, 98 user I/Os, two PLLs, and a 320 MHz maximum internal frequency on a 1.5V core. It is housed in a 144-pin TQFP package measuring 22x22 mm with 0.5 mm pitch and supports PS, AS, and JTAG configuration. These parameters collectively define the Cyclone I mid-density, low-cost FPGA tier for high-volume digital designs.

選型指南
Choose the EP1C6T144C7N when your design needs up to 5980 logic elements, 92160 bits of block RAM, and up to 98 user I/Os in a hand-reworkable 144-TQFP package. It is the right Cyclone I tier for industrial control, video pipeline, telecom bridging, and embedded coprocessor applications where cost and supply continuity dominate over cutting-edge features. Choose the C8 speed grade (EP1C6T144C8N) instead when timing closure is tight. Choose the EP1C3T144C8N only when you need fewer LEs and lower cost in the same footprint, and migrate to EP1C12 or Cyclone II/III when logic or RAM demand exceeds EP1C6 capacity.

設計說明
Estimated: at 100% resource utilization (5980 LEs, 20 M4K blocks, all 98 I/Os toggling at 100 MHz), the EP1C6T144C7N draws roughly 300-500 mA from VCCINT and 100-200 mA from VCCIO. Place 100 uF bulk + 0.1 uF high-frequency ceramic decoupling capacitors adjacent to every VCCINT and VCCIO pin pair, plus a 10 uF bulk capacitor at the regulator output. The Cyclone Device Handbook's powerplay estimator tool provides device-specific numbers for your design before committing to a regulator.
Route the dedicated clock input pins (CLK[0..3] on the EP1C6T144) as 50-ohm controlled-impedance traces, length-matched within 100 mils if used for a DDR-style or source-synchronous interface. Keep JTAG chain signals (TCK, TMS, TDI, TDO) away from fast switching I/O to avoid configuration-mode interference. The 0.5 mm pitch TQFP package requires 4-mil trace-and-space design rules; plan escape routing accordingly.
Do not power the EP1C6T144C7N with VCCIO=3.3V while VCCINT=1.5V out of sequence during hot-plug events - always ramp VCCINT before or simultaneously with VCCIO. Always issue a CONFIG_DONE acknowledge check after configuration; a missing CONFIG_DONE signal is the most common cause of 'blank' Cyclone I designs. Verify the bitstream was generated for the correct device ID (EP1C6) and package (T144) in Quartus II - bitstreams targeting a different package or family member will not configure correctly.
