FC80486DX4WB75

The FC80486DX4WB75 is an Intel i486-series microprocessor featuring the Intel486 GX core. It provides a single 32-bit core running at 75 MHz with an integrated floating-point unit (FPU).

Designed for embedded applications, this commercial-grade, surface-mount device offers 3.3 V I/O, a 208-pin SQFP package (28×28), and an operating temperature range of 0 °C to 85 °C for use in a variety of embedded and commercial electronic designs.

Key Features

• Core and Architecture  Intel486 GX core with a single 32-bit processor core operating at 75 MHz for general-purpose embedded processing.
• Integrated FPU  On-chip floating-point unit to accelerate arithmetic and numeric workloads without requiring a separate coprocessor.
• I/O Voltage  3.3 V I/O level for compatibility with common 3.3 V system logic and peripherals.
• Package and Mounting  Supplied in a 208-pin SQFP (28×28) / 208-BFQFP package, intended for surface-mount assembly on PCBs.
• Commercial Grade Operating Range  Rated for commercial use with an operating temperature range of 0 °C to 85 °C.
• Standards Compliance  RoHS compliant, meeting common environmental regulation requirements for lead-free assemblies.
• Graphics Acceleration  No onboard graphics acceleration (specified as "No").

Typical Applications

• Embedded systems  Use as a 32-bit processing core in embedded designs that require a compact, surface-mount microprocessor.
• Surface-mount PCB assemblies  208-pin SQFP package suited for high-pin-count, surface-mount board layouts.
• Commercial electronic products  Commercial-grade rating and 0 °C to 85 °C operating range for general-purpose commercial applications.
