EP2C8T144C7N 概要

The Intel (formerly Altera) EP2C8T144C7N is a Cyclone II Field-Programmable Gate Array (FPGA) with 8256 logic elements, 165888 bits of embedded RAM, and 85 user I/Os, housed in a 144-pin LQFP (T144) package. It is built on a low-power 90-nm process and supports a maximum internal clock frequency of approximately 450 MHz, with Multiplier blocks and embedded M4K RAM for DSP-oriented glue logic.

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.

🖥️

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.

📻

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.

EP2C8T144C7N vs EP2C8Q208C7N - which is better for a high-I/O bridge design?

For a high-I/O bridge design, the EP2C8Q208C7N (208-pin PQFP, 138 user I/Os) provides 53 percent more user I/Os than the EP2C8T144C7N (85 user I/Os) while keeping the same 8,256-LE Cyclone II die. Choose the Q208 variant when you need more than 85 I/Os; choose the T144 when PCB area is constrained and 85 I/Os suffice. Both share identical silicon, so timing closure and IP portability are unchanged.

What is the best drop-in replacement for the EP2C8T144C7N?

The best drop-in replacement for the EP2C8T144C7N in the same 144-LQFP package is the EP2C8T144C8N (speed grade 8, faster timing closure) or the EP2C8T144I8N (industrial temperature -40C to +100C) if your design needs wider thermal headroom. Both reuse the identical T144 footprint; pin migration is transparent in Quartus. For new designs, prefer the EP4CE6E144 (Cyclone IV E) as a long-term production alternative.

Can the EP2C8T144C8N replace the EP2C8T144C7N?

Yes, the EP2C8T144C8N is a drop-in replacement for the EP2C8T144C7N in the same 144-LQFP (T144) package. The only differences are a faster speed grade (8 vs 7, allowing tighter fMAX) and identical logic, RAM, multipliers, and PLL resources. Per the Cyclone II speed-grade table, the C8 device meets all timing specifications of the C7 device at the same voltage and temperature, so existing C7 bitstreams run without modification.

What is the best Lattice equivalent for the EP2C8T144C7N?

The best cross-brand Lattice equivalent for the EP2C8T144C7N is the Lattice iCE40 HX series in a 144-pin TQFP package, such as the iCE40HX1K-VQ100 or HX4K-CB132 with adapter PCB. According to distributor cross-reference tools, there is no pin-compatible cross-brand part in the same T144 footprint; expect a PCB adapter or design rework for migration. Verify timing closure and IP porting using Lattice iCEcube2.

Where to find the EP2C8T144C7N pinout?

The EP2C8T144C7N pinout is documented in the Cyclone II Device Handbook pin tables for package code T144. The 144-LQFP package has 85 user I/O pins, 8 dedicated clock inputs, 4 configuration-related pins, plus VCCINT, VCCIO, GND, and JTAG pins. Each bank (1 through 8) has independent VCCIO rails supporting mixed-voltage interfaces. Always cross-reference the pin table against the Quartus pin-assignment file (.qsf) when migrating board layouts.

選定ガイド

Choose the EP2C8T144C7N when you need an 8,256-LE Cyclone II FPGA in a 144-LQFP package for a production design that already has a verified bitstream, or for cost-sensitive new designs where the part is still in distributor stock. If you need tighter fMAX margin (especially for high-multiplier DSP), choose the EP2C8T144C8N in the same package. For industrial-temperature deployment (-40C to +100C), use the EP2C8T144I8N. For new designs that will outlive Cyclone II supply, migrate to the EP4CE6E144C8N (smaller but active) or EP4CE10E144C8N (larger and active) in the same 144-LQFP footprint. Cross-brand Lattice iCE40 migration requires a PCB adapter because no pin-compatible T144 variant exists. All same-brand alternatives above are pin-compatible with the EP2C8T144C7N footprint.

設計ノート

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.
