NS486SXL-25

The NS486SXL-25 is an Intel486 SX microprocessor IC from the NS486 series by Texas Instruments. It integrates a single 32-bit Intel486 SX core running at 25 MHz and is designed for embedded and commercial applications that require modest 32-bit processing and DRAM support.

With 5 V I/O, an Access.bus interface, and a surface-mount 132-pin PQFP footprint, the NS486SXL-25 targets embedded system designers needing a compact, compliant solution with a defined commercial temperature range.

Key Features

• Core Processing  Single Intel486 SX core delivering 32-bit processing at a clock rate of 25 MHz for control and compute tasks.
• Memory Support  Integrated support for DRAM controllers to simplify system memory interfacing and expandability.
• Interfaces  Access.bus interface available for system-level communication and peripheral connectivity.
• Power and I/O  5 V I/O levels compatible with common commercial embedded logic families.
• Package and Mounting  132-pin device in a bumpered 132-BQFP package; supplier device package listed as 132-PQFP with a 24.13 × 24.13 mm footprint for surface-mount applications.
• Operational Grade and Range  Commercial grade device rated for operation from 0 °C to 70 °C.
• RoHS Compliance  RoHS-compliant manufacturing for regulatory alignment in commercial products.

Typical Applications

• Embedded controllers  Use as the main processing element in commercial embedded systems that require 32-bit control and DRAM interfacing.
• Equipment refurbishment and maintenance  Suitable for replacement or repair in legacy hardware designs that use Intel486 SX functionality and PQFP mounting.
• Human-machine interfaces  Drive basic user-interface logic and peripheral coordination in commercial devices.

Unique Advantages

• Established Intel486 SX core: The processor provides proven 32-bit architecture at a fixed 25 MHz clock for predictable performance in established designs.
• Integrated DRAM controller support: Simplifies memory subsystem design and reduces additional controller components.
• Standard 5 V I/O: Ensures compatibility with common commercial logic levels and simplifies power-domain design.
• Surface-mount 132-pin PQFP footprint: Compact 24.13 × 24.13 mm package suitable for typical PCB layouts and automated assembly.
• Commercial temperature rating: Clear 0 °C to 70 °C operating range for mainstream commercial product deployments.
• RoHS compliant: Supports compliance needs for commercial product manufacturing.

Why Choose NS486SXL-25?

The NS486SXL-25 balances a classic 32-bit Intel486 SX core with system-oriented interfaces—DRAM controller support and Access.bus—packaged in a 132-pin PQFP for surface-mount assembly. Its 5 V I/O and commercial operating range make it well-suited for designers maintaining or developing commercial embedded systems that require predictable, midrange processing capability.

Manufactured by Texas Instruments as part of the NS486 series, this device provides a clear specification set for procurement and design integration, offering RoHS compliance and a defined temperature grade for steady long-term use in commercial equipment.
