DS3884AVFN

Drivers, Receivers, Transceivers Overview

The DS3884AVFN is a high-performance, low-power CMOS 16-bit microprocessor manufactured by Rochester Electronics. It implements the Motorola MC68000 architecture and operates at a clock frequency of 25 MHz. The device features a 16-bit external data bus and a 32-bit internal address bus, supporting up to 16 MB of linear memory addressing. It includes integrated cache logic for improved instruction execution speed. The component is housed in a 100-lead Plastic Flat Package (PFP) with a 1.4-inch body length, designed for industrial and commercial temperature ranges.

• Integrates on-chip cache logic to accelerate processor performance.
• Supports 16-bit external data transfer with 32-bit internal processing paths.
• Provides comprehensive interrupt handling capabilities for system control.

Drivers, Receivers, Transceivers Applications

• Industrial automation controllers requiring deterministic real-time processing.
• Avionics systems utilizing legacy 68K-based architectures.
• Test and measurement equipment needing high-speed data acquisition.
• Telecommunications infrastructure maintaining backward compatibility.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'VFN' against the manufacturer's official datasheet to confirm package type and temperature range specifications. Ensure that the die revision matches the required reliability standards for the target application. Request lot traceability documentation to validate manufacturing origin and date code authenticity prior to finalizing any acquisition or integration plan.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a 25 MHz MC68000-compatible core is required with integrated cache support. Compare pinout compatibility with existing PCB layouts designed for standard 100-lead PFP packages. Evaluate power consumption requirements against the CMOS technology specifications provided in the electrical characteristics section of the official documentation.

Drivers, Receivers, Transceivers Part Context

Rochester Electronics specializes in providing lifecycle management solutions for obsolete and hard-to-find semiconductors. This part represents a continuation source for the MC68000 family, ensuring supply continuity for long-life applications where original manufacturers have discontinued production. The company maintains inventory and manufacturing capabilities for these legacy devices.

Drivers, Receivers, Transceivers Replacement Considerations

Direct functional equivalents include other MC68000 variants operating at similar frequencies. Verify pin compatibility before substituting with different package options from other vendors. Cross-reference with MC68EC000 series if reduced pin count is acceptable, though cache implementation may differ.
