MC68882RC33A

Specialized ICS Overview

The MC68882RC33A is a floating-point co-processor manufactured by Freescale Semiconductor. It is designed to accelerate arithmetic operations for compatible microprocessors, specifically the MC68020 and MC68030 families. The device operates at a maximum clock frequency of 33 MHz and utilizes a 68-pin Ball Grid Array (BCPGA) package with through-hole mounting capabilities. Its primary function is to handle complex mathematical calculations, offloading these tasks from the main CPU to improve system performance in embedded applications requiring high-speed numerical processing.

Specialized ICS Feature Summary

• Floating-point co-processor architecture optimized for MC68020/MC68030 compatibility
• Maximum operating frequency of 33 MHz
• 68-pin BCPGA package (26.92x26.92 mm) suitable for through-hole installation

Specialized ICS Applications

• High-performance computing systems utilizing Motorola 68000 series processors
• Embedded control units requiring accelerated mathematical computations
• Industrial automation controllers needing precise floating-point arithmetic

Specialized ICS Procurement Notes

Verify component authenticity and physical condition upon receipt. Confirm the 68-PGA package dimensions match design specifications. Check for manufacturing date codes relevant to project lifecycle requirements. Ensure proper handling procedures are followed due to the through-hole mounting type and potential sensitivity to thermal stress during assembly.

Specialized ICS Selection Notes

Select this component when integrating with MC68020 or MC68030 processors requiring dedicated floating-point acceleration at 33 MHz. Ensure the PCB layout supports the 68-BCPGA footprint and through-hole assembly processes. Consider thermal management solutions appropriate for the plastic encapsulated chip carrier form factor under continuous operation conditions.

Specialized ICS Part Context

This part belongs to the MC68882 family of floating-point co-processors originally developed by Motorola and later produced by Freescale/NXP. These components were widely used in workstations and embedded systems during the 1980s and 1990s to enhance the computational capabilities of the 68k processor family before integrated FPU solutions became standard in later generations.

Specialized ICS Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the specialized nature and age of the MC68000 series co-processors, direct pin-to-pin replacements may be limited. Verify compatibility with existing system bus timing and voltage levels if considering alternative sources within the same product family.
