NG80386SXLP25

The NG80386SXLP25 is an Intel386 SX microprocessor delivered in a 100-PQFP (19×19) surface-mount package. It implements a single 32-bit core running at 25 MHz with support for the Intel387 SX math co-processor and an integrated DRAM controller.

Designed for embedded applications and commercial-grade systems, this part offers a 5 V I/O voltage and an operating temperature range of 0 °C to 100 °C. The device is RoHS compliant and supplied in a standard 100-QFP footprint for board-level integration.

Key Features

• Core Single Intel386 SX core; 32-bit architecture suitable for representative embedded processing tasks.
• Clock Speed 25 MHz operating frequency for predictable, fixed-frequency system timing.
• Voltage 5 V I/O specification for compatible interface levels with legacy and contemporary 5 V systems.
• Co-processor Support Supports the Intel387 SX math engine to offload floating-point and math-intensive operations.
• Memory Integrated DRAM controller to interface with external DRAM memory subsystems.
• Package & Mounting 100-PQFP (19×19) surface-mount package for standard board placement and assembly.
• Operating Range & Grade Commercial grade with an operating temperature range of 0 °C to 100 °C.
• Environmental Compliance RoHS compliant for regulatory and environmental compatibility.

Typical Applications

• Embedded systems — Use as the main MPU in embedded designs requiring a 32-bit core and external DRAM support.
• Systems using numeric co-processing — Deploy where Intel387 SX co-processor support is needed for floating-point or math acceleration.
• Board-level designs — Ideal for PCBs designed around a 100-PQFP (19×19) surface-mount footprint.
• Commercial temperature-range products — Suitable for applications operating within 0 °C to 100 °C.

Unique Advantages

• 32-bit single-core architecture: Delivers a straightforward 32-bit processing model for embedded workloads.
