EPF8282ATC100-4

The EPF8282ATC100-4 is a FLEX 8000 family programmable logic device offered by Intel. It provides a register-rich, CMOS-based programmable logic architecture with 208 logic elements implemented in 26 logic array blocks, and approximately 2,500 usable gates—suitable for commercial embedded and control applications.

Designed for 5.0 V systems, the device targets applications such as bus interfaces, high-speed controllers, DSP building blocks, and TTL/logic integration where on-board reconfigurability, predictable interconnect, and flexible I/O are required.

Key Features

• Core & Logic 208 logic elements organized across 26 logic array blocks (LABs) delivering roughly 2,500 usable gates and 282 flip-flops for register-rich implementations.
• In-system Configuration Supports in-circuit reconfigurability (ICR) via external configuration devices or an intelligent controller as described for the FLEX 8000 family.
• I/O and Voltage 78 user I/O pins with MultiVolt I/O interface concepts in the FLEX 8000 family; device supply specified for 4.75 V to 5.25 V operation.
• Interconnect & Arithmetic Support Continuous routing structure with dedicated carry and cascade chains for efficient implementation of adders, counters and high-fan-in logic (features described for the FLEX 8000 family).
• System & Test Family-level support for JTAG boundary-scan test circuitry on selected devices and peripheral register options for fast setup and clock-to-output timing.
• Package & Mounting Surface-mount 100‑TQFP package (14×14 mm) suited for compact PCB designs; commercial-grade operating range 0 °C to 70 °C.
• Standby Power Family guidance lists low standby current (typical specification noted at 0.5 mA or less), supporting low-power idle states.
• RoHS Compliance Device is RoHS compliant for environmental and regulatory considerations.
• Design Tool Support FLEX 8000 family devices are supported by the MAX+PLUS II development system and standard HDL/netlist flows for integration into existing toolchains.

Typical Applications

• Bus Interfaces and TTL Integration Use the device to implement parallel bus bridges, level translation and glue logic where 78 I/O pins and 5 V signaling are required.
• Control and High-Speed Controllers Implement control logic, timers and custom state machines that benefit from the device’s register count and dedicated arithmetic chains.
• Digital Signal and Data Path Processing Deploy as a compact DSP or wide-data-path element for data transformation and manipulation using the available flip-flops and logic elements.
• Coprocessor and Peripheral Integration Integrate peripheral control or coprocessor functions alongside other system components, leveraging on-board reconfigurability for iterative development.

Unique Advantages

• Compact, surface-mount package: 100‑TQFP (14×14) provides a small PCB footprint while offering 78 user I/O pins for dense designs.
• 5 V system compatibility: Specified supply range of 4.75 V to 5.25 V matches 5.0 V logic systems and simplifies interfacing in legacy environments.
• Register-rich architecture: 282 flip-flops and 208 logic elements enable efficient state-machine and pipelined implementations without external registers.
• In-circuit reconfigurability: Supports ICR via external configuration devices or intelligent controllers for field updates and iterative development cycles.
• Predictable routing and arithmetic support: Family-level continuous routing plus dedicated carry and cascade chains streamline implementation of adders, counters and high-fan-in logic.
• Toolchain compatibility: Supported by the MAX+PLUS II development environment and common HDL/netlist formats for rapid design entry and synthesis.
