EPF81500AQC240-2

The EPF81500AQC240-2 is a FLEX 8000 family field programmable device in a 240-pin BFQFP package optimized for commercial applications. Architected as a register-rich CMOS programmable logic device, it provides 1,296 logic elements (approximately 16,000 usable gates) and 181 user I/O pins to implement glue logic, bus interfaces, control functions, and mid-density logic integration.

Designed for 5.0 V core operation and support for mixed I/O signaling at the family level, this device targets system designs that require flexible logic resources, predictable routing behavior, and a compact surface-mount package.

Key Features

• Core Capacity — 1,296 logic elements and approximately 16,000 usable gates, providing a medium-to-high logic resource for glue logic, controllers, and bus interfacing.
• Register Density — Part of the FLEX 8000 family known for a high register count suitable for datapath and state machine implementations.
• I/O — 181 user I/O pins to support multiple buses and peripheral connections in a single device footprint.
• Power and Supply — Operates from a 4.75 V to 5.25 V supply range, matching common 5 V system rails.
• Package & Mounting — 240-BFQFP package (supplier device package: 240-PQFP, 32 × 32) with surface-mount mounting for compact PCB integration.
• Operating Range & Grade — Commercial grade device with an operating temperature range of 0 °C to 70 °C.
• On-chip Memory — No embedded RAM bits reported for this device.
• Standards & Compliance — RoHS-compliant supply status for environmental compliance.
• FLEX 8000 Family Capabilities — Family-level features include in-circuit reconfigurability (ICR), FastTrack continuous routing, dedicated carry and cascade chains for arithmetic and high-fan-in logic, and JTAG boundary-scan on selected devices.
• Design Tool Support — FLEX 8000 family devices are supported by Altera's MAX+PLUS II development tools and common EDA tool flows (family-level information provided in datasheet).

Typical Applications

• Bus Interfaces and Glue Logic — Use the device’s 181 I/O pins and 1,296 logic elements to implement multi-bus bridging, address decoding, and protocol translation in 5 V systems.
• Peripheral Controllers — Implement custom peripheral control, handshake logic, and interface sequencing where mid-range logic density and many I/Os are required.
• High-Register DSP Front-Ends — Leverage the family’s register-rich architecture for data path staging and parallel processing front-ends that require significant flip-flop resources.
• System Glue for Embedded Platforms — Consolidate discrete logic and multiple interface drivers into a single surface-mount device to reduce BOM and board area.

Unique Advantages

• Medium-to-High Logic Capacity: 1,296 logic elements and ~16,000 gates allow consolidation of complex glue logic and moderate application functions into one device.
• Generous I/O Count: 181 user I/O pins enable integration of multiple buses or peripheral interfaces without external multiplexing.
• 5 V System Compatibility: 4.75 V–5.25 V supply range aligns with established 5 V legacy and industrial controller platforms.
• Compact Surface-Mount Package: 240-BFQFP (32 × 32) enables high pin-count implementations in a manufacturable surface-mount form factor.
• Family-Level Routing & Arithmetic Support: FLEX 8000 architecture includes FastTrack interconnect and dedicated carry/cascade chains, simplifying implementation of arithmetic and wide-logic functions.
• RoHS Compliance: Environmentally compliant supply status supports modern manufacturing and procurement requirements.
