EP1C4F400C8

The EP1C4F400C8 is an Intel Cyclone® field programmable gate array (FPGA) device built on the Cyclone family architecture. This device provides 4,000 logic elements, approximately 78 Kbits of embedded RAM, and up to 301 user I/O pins in a compact 400‑BGA package.

Designed for data‑path and general embedded logic applications, the EP1C4F400C8 combines on‑chip memory and programmable logic with dedicated clocking resources and a broad set of I/O options to support external memory interfaces and system interconnects. It is supplied in a surface‑mount 400‑FBGA (21×21) package and rated for commercial temperature operation.

Key Features

• Core Logic  4,000 logic elements provide a mid‑density programmable fabric suitable for a wide range of custom logic and control functions.
• Embedded Memory  Approximately 78 Kbits (78,336 total RAM bits) of on‑chip RAM organized into M4K blocks for data buffering and small memory structures.
• I/O Capacity & Standards  Up to 301 user I/O pins enable dense external connectivity. The Cyclone family supports common I/O standards including LVTTL, LVCMOS, SSTL, and LVDS (family data).
• Clocking  Device architecture includes up to two phase‑locked loops (PLLs) for clock multiplication and phase control, supporting common clocking needs (family data).
• Packaging & Mounting  400‑BGA package (supplier device package: 400‑FBGA, 21×21) designed for surface‑mount assembly, enabling compact board layouts.
• Power  Core supply voltage range specified at 1.425 V to 1.575 V to match Cyclone-family power requirements.
• Operating Range & Grade  Commercial grade with an operating temperature range of 0 °C to 85 °C and RoHS compliance for environmental compatibility.

Typical Applications

• Data‑path processing  Use the programmable logic and on‑chip RAM to implement customized data processing pipelines and buffering in communications and signal‑processing tasks.
• Memory interface and bridging  The device supports external memory interfaces (family-level support for DDR SDRAM and other memories), making it suitable for memory controller logic and protocol bridging.
• ASSP/ASIC interfacing and prototyping  With up to 301 I/O pins and support for common I/O standards, the device can interface with ASSP/ASIC devices and serve in prototype or system glue logic roles.
• Embedded control and I/O‑rich systems  Combine logic elements and abundant I/O to implement control engines, sensor interfaces, and custom peripheral handling in compact designs.

Unique Advantages

• Right‑sized logic and memory: 4,000 logic elements and ~78 Kbits of embedded RAM deliver a balanced resource set for mid‑range FPGA designs without excess complexity.
• High I/O density: Up to 301 user I/O pins enable extensive external connectivity for interfaces, buses, and peripherals.
• On‑chip clocking resources: Integrated PLLs provide flexible clocking options to support multi‑clock designs and timing adjustments.
• Compact BGA footprint: The 400‑FBGA (21×21) package supports dense PCB layouts while maintaining surface‑mount compatibility.
• Commercial temperature and RoHS compliance: Commercial grade operation (0 °C to 85 °C) and RoHS compliance support standard electronic product requirements.
