EP4CE6F17I8LN 概述

The Intel (formerly Altera) EP4CE6F17I8LN is a low-cost, low-power Cyclone IV E FPGA featuring 6,272 logic elements (LEs), 392 Kbits of embedded memory, and 179 maximum user I/Os, housed in a 256-ball FineLine BGA (FBGA-256) package. Built on a 60 nm TSMC process, this industrial-temperature-grade device operates across -40C to +100C with core voltages of 1.0V/1.2V and I/O voltages from 1.2V to 3.3V. The device integrates 15 embedded 18x18 multipliers and supports up to 4 PLLs, making it well suited for cost-sensitive digital logic, glue logic, and DSP front-end designs.

An FPGA (Field Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs) connected via programmable interconnect, allowing designers to implement arbitrary digital circuits after fabrication. FPGAs sit within the broader taxonomy of programmable logic devices (PLDs), alongside CPLDs, and are commonly used to prototype ASIC designs, accelerate parallel DSP algorithms, or provide flexible I/O bridging in industrial systems. The Cyclone IV E family targets high-volume, cost-optimized applications where the flexibility of an FPGA matters more than the highest possible density.

Key features include Cyclone IV E architecture with up to 6,272 LEs and 392 Kbits of embedded RAM, 179 user I/Os supporting LVDS, LVTTL, LVCMOS, SSTL, and other I/O standards, integrated 18x18 multipliers for DSP blocks, four general-purpose PLLs for clock management, and support for external memory interfaces including DDR2 SDRAM and QDRII SRAM.

The architecture pairs logic-array blocks (LABs) with M9K embedded memory blocks, multiplier blocks, and a flexible routing fabric. Its static core power is low enough that the device can be cooled with a modest PCB thermal pattern, and the FPGA is configured via standard JTAG or active/parallel configuration schemes using low-cost EPCS serial configuration devices.

Typical applications include industrial motor control and PLC interfaces, factory automation and protocol bridging, low-cost video processing for surveillance, USB and UART-based bridge logic, and educational/rapid-prototyping platforms that benefit from Quartus II Web Edition support.

When designing with the EP4CE6F17I8LN, ensure adequate decoupling on every I/O bank supply pin and follow Altera's recommended FBGA-256 PCB layout guidelines for fine-pitch BGA escape routing. Plan configuration-mode selection (AS, PS, JTAG) early because the MSEL pins are not recoverable after PCB fabrication.

This page synthesizes distributor pricing, drop-in FPGA alternatives, and practical Quartus II design notes not found in the manufacturer datasheet alone.

What is the logic element count of the EP4CE6F17I8LN?

The EP4CE6F17I8LN contains 6,272 logic elements (LEs) organized into 392 logic array blocks (LABs). According to the Cyclone IV E datasheet, the EP4CE6 family member targets low-density, cost-optimized designs while still providing 276,480 bits of embedded RAM, 15 embedded 18x18 multipliers, and 4 PLLs - the lowest-cost device in the Cyclone IV E family.

How many user I/Os does the EP4CE6F17I8LN provide?

The EP4CE6F17I8LN provides up to 179 user I/Os distributed across the 256-ball FBGA package. The I/O supports LVTTL, LVCMOS, SSTL, LVDS, and RSDS standards with per-bank voltage scaling from 1.2V to 3.3V. Industrial-grade I/O banks allow mixed-voltage interfacing to MCUs, DDR2 memory, and LVDS peripherals.

What package does the EP4CE6F17I8LN use and what are its dimensions?

The EP4CE6F17I8LN uses a 256-ball FineLine BGA (FBGA) package measuring 17 mm x 17 mm with 1.0 mm ball pitch. The 'F17' code in the part number designates the 17 x 17 mm FBGA-256 footprint, while 'I8' indicates industrial temperature and 8-speed grade. Lead-free and RoHS-compliant per FindIC and Arrow listings.

Where can I buy the EP4CE6F17I8LN online and what is the lead time?

The EP4CE6F17I8LN is in stock at DigiKey, Mouser, Arrow, and Octopart-listed distributors as of 2026-09-10. Per the DigiKey listing, ships today with qty-1 unit price around $28.50 USD. Lead time for volume orders of 1,000+ units is typically 6-10 weeks when sourced through authorized channels. Pricing reflects current Intel/Altera distributor pricing.

What is the difference between EP4CE6F17I8LN and EP4CE6F17C6N?

The EP4CE6F17I8LN is industrial temperature (-40C to +100C) and speed grade 8, while the EP4CE6F17C6N is commercial temperature (0C to +85C) and speed grade 6 (faster Fmax). Both share the same FBGA-256 package and 6,272 LE architecture, but the I8LN is preferred for harsh environments and the C6N is preferred for performance-critical commercial designs where the temperature range allows.

What is the best drop-in replacement for the EP4CE6F17I8LN?

The closest drop-in replacement is the EP4CE6F17I8L (commercial or industrial temperature without the N-lead-free marker) on the same FBGA-256 footprint, both 6,272 LEs. For a same-package pin-compatible upgrade, consider the EP4CE10F17I8N (10,320 LEs in the same FBGA-256) if your design can tolerate the higher density. Always verify Quartus pin assignments before swapping.

Where do I download the EP4CE6F17I8LN datasheet PDF?

The Cyclone IV E device datasheet containing EP4CE6F17I8LN specifications is hosted on the Altera/Intel website at the device handbook URL. Designers should consult Chapter 1 (Device Datasheet) of the Cyclone IV Device Handbook for full electrical characteristics, I/O timing, and configuration specifications, plus the pin-out file in the Quartus II design software.

What configuration modes does the EP4CE6F17I8LN support?

The EP4CE6F17I8LN supports JTAG (IEEE 1149.1), Active Serial (AS) using EPCS4/EPCS16/EPCS64 configuration devices, and Passive Serial (PS) modes. The MSEL[2:0] pins select between AS standard/fast and PS/JTAG modes and must be set with resistors at PCB boot. Configuration typically completes within 100 ms from a 40 MHz EPCS clock.

What are the key engineering specifications of EP4CE6F17I8LN that engineers should know?

The EP4CE6F17I8LN integrates 6,272 LEs (Cyclone IV E), 270 Kbits embedded RAM in 30 M9K blocks, 15 hard 18x18 multipliers, 4 PLLs, 179 user I/Os, and a 1.2V core with 1.2V-3.3V I/O banks. The 60 nm low-power process yields static power well under 100 mW. Industrial -40C to +100C operation and 256-ball FBGA at 1.0 mm pitch make it the smallest-density Cyclone IV E variant.

Is EP4CE6F17I8LN suitable for industrial motor control applications?

Yes, the EP4CE6F17I8LN is widely used in industrial motor control, PLC interfaces, and factory automation. Its industrial -40C to +100C temperature range, 4 PLLs for precise PWM generation, and 15 hardware multipliers for fast Clarke/Park transforms make it ideal for field-oriented control (FOC) loops. The 179 I/Os easily interface to resolver-to-digital converters, gate drivers, and encoder feedback lines.

EP4CE6F17I8LN vs EP4CE6F17C6N - which is better for harsh environment?

For harsh-environment industrial designs, the EP4CE6F17I8LN is the better choice because of its -40C to +100C industrial temperature range. The EP4CE6F17C6N is limited to commercial 0C to +85C, restricting it to controlled-temperature enclosures. The trade-off is Fmax: the C6N speed grade 6 is faster than the I8LN speed grade 8, so for timing-critical commercial designs, the C6N may still win.

选型指南

Choose EP4CE6F17I8LN when you need a low-cost, industrial-temperature Cyclone IV E FPGA for designs that fit within 6,272 LEs and require -40C to +100C operation. It is the lowest-density Cyclone IV E variant, making it ideal for glue logic, motor-control FOC loops, protocol bridging, and education platforms. For designs needing more headroom, choose the EP4CE10F17I8N (+64% LEs, same FBGA-256 footprint) or EP4CE15F17I7N (+146% LEs). For commercial-temperature only deployments where Fmax matters more than temperature, the EP4CE6F17C6N (speed grade 6) or EP4CE6F17C8N (speed grade 8) are cost-equivalent alternatives. All variants share the FBGA-256 footprint, allowing PCB layout reuse across density grades.

设计说明

Estimated: the FBGA-256 package uses a 17 x 17 mm footprint with 1.0 mm ball pitch, which requires 4 to 6 PCB layers with microvia-in-pad or HDI construction for clean signal escape. Place a continuous GND plane directly under the BGA, and flood the outer layers with VCCINT and VCCIO power planes tied to the inner balls. Per Cyclone IV E handbook, route each I/O bank supply (VCCIO1-8) to its respective bank balls with 0.1uF + 10uF decoupling within 100 mil of every ball. SDC files in Quartus II assume 50 ohm controlled-impedance traces.

Estimated: core power VCCINT draws between 50 mA (static, no I/O activity) and 500 mA (fully utilized LE/multiplier fabric) at 1.2V. Use a dedicated LDO such as the LT3085 or TPS7A45 for VCCINT to keep ripple under 30 mVpp. Sequence VCCINT before VCCIO to prevent I/O driving into unpowered logic. PLL analog supplies VCCA1-4 require additional LC filtering (ferrite bead + 10uF) per the device handbook to meet jitter specs.

Verify MSEL[2:0] pin strapping before PCB fab - the configuration mode (AS standard, AS fast, PS, JTAG) is latched at power-up and cannot be changed in firmware. Do not leave JTAG pins (TCK/TMS/TDI/TDO) floating; TMS and TDI require 10 kohm pull-ups to VCCIO8. The nCONFIG, nSTATUS, and CONF_DONE pins are open-drain and need external 10 kohm pull-ups to VCCIO8. Cyclone IV E is configured via 3.3V EPCS devices, so VCCIO8 must be 3.3V in AS mode.

Estimated: FBGA-256 has a theta_JA of about 18 C/W with a 4-layer JEDEC test board, so a fully utilized EP4CE6F17I8LN drawing 600 mW of core power reaches a junction-to-ambient rise of ~11C above ambient. Industrial grade limits operation to 100C junction; in a sealed industrial enclosure at 70C ambient, even modest margin remains. Use thermal vias under the center ball array to spread heat into inner GND planes.
