EP20K400CF672I8

The EP20K400CF672I8 is an APEX-20KC series field programmable gate array (FPGA) in a 672-ball BGA package, designed for industrial applications requiring medium-to-high logic density and flexible I/O. The device integrates a MultiCore architecture that combines look-up table (LUT) logic and embedded memory to address compute-intensive and memory-buffered functions.

Targeted at systems that need reprogrammable logic, on-chip memory, and robust I/O capability, this device delivers a balance of integration, performance, and temperature range for demanding embedded and industrial designs.

Key Features

• Core Fabric — 16,640 logic elements providing programmable logic resources to implement complex digital functions; approximately 1,052,000 system gates.
• Embedded Memory — Approximately 0.213 Mbits (212,992 bits) of on-chip RAM suitable for FIFOs, dual-port RAM, and other buffering tasks.
• I/O and Interfaces — Up to 488 user I/O pins, with MultiVolt I/O support noted in the APEX-20KC series for multiple interface voltages; programmable output slew-rate and individual tri-state control are supported by the family architecture.
• Clock and Timing — Flexible clock management architecture described for the APEX-20KC family, including support for up to four PLLs and up to eight global clock signals for low-skew system clocking.
• Power and Voltage — Internal supply operates around 1.8 V with the device data indicating supply range of 1.71 V to 1.89 V; copper interconnect in the family reduces power consumption.
• Package and Mounting — 672-BBGA (supplier package 672-FBGA, 27 × 27 mm) designed for surface-mount assembly.
• Operating Range — Industrial-grade temperature rating from −40 °C to 100 °C for deployment in thermally challenging environments.
• Design Tools and Support — The APEX-20KC family is supported by the Quartus II development system and Altera MegaCore functions as referenced for series-level software support and IP.

Typical Applications

• High-speed memory interfaces — Use embedded RAM and extensive I/O to implement DDR and ZBT memory controllers and buffering logic.
• Communications and networking — Implement protocol processing, packet buffering, and interface bridging leveraging the device’s logic density and I/O count.
• Industrial control and automation — Deploy in control systems that require programmable logic, deterministic clocking, and operation across −40 °C to 100 °C.
• PCI and legacy bus bridging — The APEX-20KC family supports common bus interfaces at the series level for integration into systems requiring PCI and related I/O standards.

Unique Advantages

• High logic density: 16,640 logic elements and roughly 1,052,000 system gates enable implementation of complex functions on a single device, reducing board-level component count.
• On-chip buffering: Approximately 212,992 bits of embedded memory allow local storage for FIFOs and data pipelines, minimizing external memory dependence.
• Robust I/O complement: 488 user I/O pins provide flexibility for interfacing multiple peripherals and high-pin-count buses without multiplexing compromises.
• Industrial temperature capability: Rated for −40 °C to 100 °C, suitable for equipment deployed in harsh or wide-temperature environments.
• Surface-mount BGA packaging: 672-ball BGA (27 × 27 mm) enables compact board layouts while supporting high pin density.
• Clock management features: Series-level support for multiple PLLs and several global clocks simplifies timing architectures for synchronous systems.
