EPF81500ARC304-2

The EPF81500ARC304-2 is a FLEX 8000 family field-programmable gate array implemented in a high-density, register-rich CMOS architecture. With 1,296 logic elements and up to 16,000 usable gates in this device configuration, it targets applications that require dense combinational logic, abundant registers, and a high pin count in a single surface-mount package.

Designed for commercial-grade systems, this device supports 208 user I/O pins in a 304‑pin BFQFP (supplier package 304‑RQFP, 40×40) and operates from a 4.75 V to 5.25 V supply over a 0 °C to 70 °C temperature range. It is RoHS compliant and suited to bus interfaces, TTL integration, coprocessor functions, and high-speed control applications.

Key Features

• Core Architecture  1,296 logic elements delivering approximately 16,000 usable gates for dense logic implementation and register-rich designs.
• I/O Capacity  208 user I/O pins to support multi‑bus connectivity and high‑pin-count system integration.
• Package & Mounting  304‑pin BFQFP package (supplier package: 304‑RQFP, 40×40) in a surface-mount form factor for PCB assembly.
• Supply & Temperature  Nominal 5 V operation with a 4.75 V to 5.25 V supply range and commercial operating temperature 0 °C to 70 °C.
• On-chip Memory  No embedded RAM bits in this device configuration; logic and registers are available for control and datapath functions.
• System-Level Features  Family-level capabilities include in-circuit reconfigurability via external configuration devices or intelligent controllers and JTAG boundary-scan test circuitry on selected devices.
• Interconnect & Arithmetic Support  Family architecture provides a continuous routing structure and dedicated carry/cascade chains for efficient arithmetic and high‑fan‑in logic implementations.
• I/O Behavior  Programmable output slew-rate control and MultiVolt I/O support in the family enable compatibility with 5.0 V and 3.3 V logic levels while the device core operates at 5.0 V.
• Environmental Compliance  RoHS compliant for lead-free manufacturing requirements.

Typical Applications

• Bus Interfaces  High I/O count and dense logic make the device well-suited to implementing multi‑bus interfaces and glue logic for system-level connectivity.
• TTL Integration  5 V-compatible core and MultiVolt I/O enable straightforward integration with TTL-based subsystems and legacy logic levels.
• Coprocessor & Controller Functions  Register-rich architecture and dedicated arithmetic chains support coprocessor tasks, counters, and high-speed controller logic.
• High‑Pin-Count Systems  304‑pin package and 208 I/O pins allow consolidation of multiple 32‑bit buses or complex I/O routing into a single FPGA package.

Unique Advantages

• High Logic Density: 1,296 logic elements and up to 16,000 usable gates provide substantial on-chip logic capacity for complex control and datapath designs.
• Extensive I/O for System Integration: 208 user I/O pins in a 304‑pin package reduce the need for external glue logic when integrating multiple buses or peripherals.
• 5 V Operation with MultiVolt I/O: Designed around a 5.0 V core supply with I/O compatibility for 3.3 V and 5.0 V signaling, simplifying mixed-voltage board designs.
• Reconfigurability & Testability: Family support for in-circuit reconfigurability and JTAG boundary-scan enhances field updates and manufacturing test flow options.
• RoHS Compliant & Commercial Grade: RoHS compliance supports lead‑free assembly; commercial-grade temperature rating aligns with a wide range of consumer and industrial product environments (0 °C to 70 °C).
