A80486DX2DA66

The A80486DX2DA66 is a single-core, 32-bit microprocessor from Intel's i486 series, operating at 66 MHz with an integrated floating-point unit (FPU). It is offered in a 168-pin CPGA package with through-hole mounting, targeting embedded and industrial applications that require deterministic 32-bit processing.

Designed for systems requiring a fixed 5 V I/O interface and extended environmental tolerance, this device provides a combination of on-chip compute capability and package options suitable for legacy and embedded designs.

Key Features

• Core & Architecture  i486 core processor, single 32-bit core operating at 66 MHz for deterministic integer and control processing.
• Integrated Floating-Point Unit (FPU)  On-chip FPU provides hardware support for floating-point operations to offload software computation.
• Power and I/O  5 V I/O voltage specification for compatibility with systems designed around a 5 V logic domain.
• Package & Mounting  168-CPGA package (44.45×44.45 mm) listed as 168-BCPGA/168-CPGA and supplied for through-hole mounting to facilitate board-level replacement and rugged assembly.
• Operating Temperature Range  Rated for operation from −55 °C to 125 °C, supporting wide-temperature embedded and industrial environments.
• Compliance  RoHS compliant, meeting common material-restriction requirements for electronics manufacturing.
• Graphics Acceleration  No integrated graphics acceleration; compute resources are dedicated to CPU and FPU operations.

Typical Applications

• Embedded Control Systems  Use the 32-bit i486 core and integrated FPU for real-time control, sequencing and device management in embedded equipment.
• Industrial Instrumentation  Wide operating temperature and through-hole package make the device suitable for industrial instruments requiring reliable on-board processing.
• Legacy System Upgrades  Compatible packaging and 5 V I/O support maintenance or refurbishment of legacy boards and systems that utilize CPGA modules.
• Test and Measurement  Deterministic single-core performance and hardware floating-point support help with signal processing and calculation tasks in test equipment.
