EPF10K70RC240-4N

The EPF10K70RC240-4N is a FLEX 10K family field programmable gate array (FPGA) from Intel, delivered in a 240-pin BFQFP package with an exposed pad. It combines a dedicated logic array and embedded memory resources to implement megafunctions and general-purpose logic for embedded and system-level integration.

Targeted for commercial applications, this device operates from a 4.75 V to 5.25 V supply and supports in-circuit reconfigurability and JTAG boundary-scan for flexible development and testing workflows.

Key Features

• Logic Capacity – 3,744 logic elements with an available gate budget of 118,000 gates, providing substantial programmable logic resource for medium-complexity designs.
• Logic Array Blocks (LABs) – 468 LABs for structured placement of logic functions and predictable routing.
• Embedded Memory – 18,432 bits of total on-chip RAM (approximately 18 Kbits) suitable for implementing buffers, FIFOs, and other megafunction memory needs.
• I/O and Package – 189 user I/O pins in a surface-mount 240‑BFQFP exposed pad package (supplier package: 240‑RQFP, 32×32), enabling dense board integration and thermal anchoring via the exposed pad.
• Supply and Operating Range – Designed for 5.0-V systems with a specified supply range of 4.75 V to 5.25 V and commercial operating temperature from 0 °C to 70 °C.
• Reconfiguration and Test – Supports in-circuit reconfigurability via external configuration devices or JTAG; includes IEEE Std. 1149.1-compliant boundary-scan (JTAG) circuitry for board-level test access.
• Family-Level System Features – FLEX 10K family functions such as dedicated carry and cascade chains, low-skew clock distribution, and options for clock delay/skew control are available on this device family.
• RoHS Compliant – Device is RoHS compliant for lead-free assembly processes.

Typical Applications

• Embedded System Integration – Implement SOPC-style functions and custom control logic where embedded memory and reconfigurable logic reduce external component count.
• Interface and Glue Logic – Bridge between legacy and modern interfaces or consolidate discrete logic into a single programmable device using abundant I/O and LAB resources.
• Memory-Intensive Megafunctions – Use the device’s embedded RAM for FIFOs, small buffers, and other localized storage needs within custom datapaths.
• Prototyping and Development – Leverage in-circuit reconfigurability and JTAG boundary-scan to iterate hardware designs and validate board-level interconnects.

Unique Advantages

• Substantial Logic Density: 3,744 logic elements and 118,000 gates enable compact implementation of medium-complexity systems without partitioning across multiple devices.
• Integrated Memory Resources: 18,432 bits of on-chip RAM reduce the need for small external memories and simplify datapath design.
• Flexible Packaging: 240‑BFQFP with exposed pad offers a high pin count and thermal benefit for board-level assembly while maintaining a compact footprint.
• Development and Test Friendly: JTAG boundary-scan and support for in-circuit reconfiguration streamline debugging, production test, and iterative development cycles.
• Commercial Supply Compatibility: 5.0-V supply range (4.75–5.25 V) aligns with common commercial digital systems and power rails.
