EP3CLS70U484C7

The EP3CLS70U484C7 is a Cyclone® III field-programmable gate array (FPGA) offered in a 484-FBGA package. It delivers a balance of high functionality and low-power operation targeted at high-volume, cost-sensitive, and low-power applications.

Built for system integration, this device combines a large logic capacity with on-chip embedded memory and a high I/O count to support a wide range of user interfaces and clocking needs while operating within a commercial temperature range and a low core-voltage window.

Key Features

• Logic Capacity — 70,208 logic elements to implement complex combinational and sequential logic.
• On‑chip Memory — Approximately 3.07 Mbits of embedded RAM for FIFOs, buffering, and packet/stream processing tasks.
• High I/O Count — 278 user I/O pins to support diverse external interfaces and parallel connectivity.
• Low‑Voltage Core — Core supply range from 1.15 V to 1.25 V designed for low-power operation.
• Clock Management — Family-level support includes up to four PLLs per device with five outputs per PLL for flexible clock synthesis and distribution (as described for the Cyclone III family).
• Flexible I/O Standards — Family documentation lists support for common I/O standards (LVTTL, LVCMOS and multiple high-speed and differential standards) and adjustable I/O slew rates to help with signal integrity.
• Package & Mounting — 484-FBGA (supplier package: 484-UBGA, 19×19) in a surface-mount form factor for compact board-level integration.
• Commercial Temperature Grade — Rated for 0 °C to 85 °C operation suitable for commercial applications.
• RoHS Compliant — Meets RoHS environmental compliance requirements.

Typical Applications

• Portable and battery-powered devices — Low-power Cyclone III family characteristics help extend battery life and reduce cooling needs.
• Communications and networking — Large logic capacity, abundant I/Os, and on-chip memory enable packet processing, bridging, and interface adaptation.
• Video and imaging — Embedded RAM and extensive logic resources support buffering, streaming, and data-path acceleration tasks.
• Instrumentation and test equipment — Flexible I/O standards and PLL-based clocking facilitate precise timing and multi-protocol interfacing.

Unique Advantages

• Significant logic resources — 70,208 logic elements provide headroom for medium-to-large FPGA designs without moving to higher-cost families.
• Compact board footprint — 484-FBGA (484-UBGA, 19×19) package offers high pin density for space-constrained PCBs.
• Designed for low power — Family-level low-power process and optimizations reduce static power, supporting thermally constrained designs.
• Broad system integration — High memory-to-logic ratio and multi-PLL clocking options simplify implementation of integrated subsystems.
• Flexible interfacing — High I/O count and support for multiple I/O standards ease connectivity to diverse peripherals and external logic.
• Procurement-friendly compliance — Surface-mount, RoHS-compliant package suitable for modern manufacturing and assembly flows.
