EPF8820AQC208-3

The EPF8820AQC208-3 is a FLEX 8000 family programmable logic device offering a register-rich, SRAM-based architecture for glue logic, bus interfaces, and control functions. This surface-mount device provides 672 logic elements (approximately 8,000 usable gates) and up to 152 user I/O pins in a 208-pin quad-flat package, supporting designs that require moderate logic density and high pin count.

Designed for commercial-temperature applications, the device operates from a 4.75 V to 5.25 V supply and is RoHS compliant. Family-level features documented in the FLEX 8000 datasheet include advanced routing, dedicated arithmetic chains, and support for in-circuit reconfigurability via external configuration devices or an intelligent controller.

Key Features

• Core Architecture  672 logic elements (LEs) implementing compact 4-input LUTs and programmable registers within the FLEX 8000 architecture.
• Logic Capacity  Approximate 8,000 usable gates and 84 logic array blocks (LABs) for mid-range programmable logic tasks.
• I/O and Packaging  Up to 152 user I/O pins delivered in a 208-pin BFQFP package (supplier device package: 208-PQFP, 28×28). Surface-mount mounting type.
• Memory  Total on-chip RAM bits: 0 (no embedded RAM blocks in this device).
• Power and Voltage  Single-supply operation from 4.75 V to 5.25 V suitable for 5.0 V logic environments.
• Temperature and Grade  Commercial operating temperature range 0 °C to 70 °C; commercial-grade device.
• Reconfigurability & System Features  Supports in-circuit reconfigurability via external configuration devices or an intelligent controller (FLEX 8000 family capability).
• Interconnect & Arithmetic Support  FastTrack continuous routing structure with dedicated carry and cascade chains for implementing arithmetic functions and high-fan-in logic (FLEX 8000 family capability).
• Compliance & Environmental  RoHS compliant.
• Design Support  FLEX 8000 family devices are supported by vendor design tools and automatic place-and-route flows (as documented for the family in the datasheet).

Typical Applications

• Bus Interfaces  Implement multi-bus glue logic and TTL integration where multiple 32-bit buses or dense I/O are required.
• High-speed Controllers  Use for control logic in peripherals and controllers that benefit from dedicated carry/cascade chains and predictable interconnect delays.
• Coprocessor & Glue Logic  Offload custom control or sequencing functions and integrate with existing TTL systems.
• Data Transformation & DSP-Adjacent Tasks  Provide storage-rich, register-heavy logic for wide-data-path manipulation and data transformation tasks (family-level suitability documented in the FLEX 8000 datasheet).

Unique Advantages

• Mid-range Logic Density:  672 logic elements and approximately 8,000 usable gates deliver an effective balance of capacity and cost for mid-complexity designs.
• High I/O Count in a Compact Package:  152 user I/Os in a 208-pin BFQFP enable consolidation of multiple interfaces into a single device while maintaining a surface-mount footprint.
• 5 V System Compatibility:  4.75 V to 5.25 V supply range supports 5.0 V logic systems and is documented for PCI 5.0-V operation within the FLEX 8000 family.
• Deterministic Routing & Arithmetic Support:  Family-level FastTrack routing and dedicated carry/cascade chains simplify implementation of adders, counters, and high-fan-in logic with predictable timing behavior.
• Vendor Toolchain Support:  FLEX 8000 family devices are supported by vendor design software and automatic place-and-route to accelerate development and verification.
• RoHS Compliance:  Environmentally compliant for regions requiring RoHS conformance.
