MC68882CRC20A

Specialized ICS Overview

The MC68882CRC20A is a floating-point co-processor manufactured by Freescale Semiconductor. It is designed to extend the arithmetic capabilities of compatible microprocessors, specifically supporting the MC68020 and MC68030 bus architectures. The device implements IEEE 754 standard floating-point operations. It is housed in a 68-pin Ball Grid Array (BCPGA) package with dimensions of 26.92x26.92 mm. The component supports through-hole mounting and is supplied in tray packaging.

Specialized ICS Feature Summary

• Floating-point co-processor for MC68020/MC68030 systems
• 68-BCPGA package (68-PGA, 26.92x26.92 mm)
• Through-hole mounting type

Specialized ICS Applications

• MC68020-based system expansion
• MC68030-based system expansion

Specialized ICS Procurement Notes

Verify the specific speed grade suffix '20' against official NXP/Freescale documentation, as local data does not specify the maximum clock frequency. Confirm availability status, as related MC68882 variants are marked as obsolete or discontinued in public records. Ensure the 68-BCPGA package compatibility with the target PCB footprint.

Specialized ICS Selection Notes

Select this component when integrating floating-point arithmetic into Motorola 68000 series environments requiring IEEE 754 compliance. Compare pinout and electrical characteristics with other MC68882 variants (e.g., CRC16, CRC25) to ensure timing compatibility with the host processor's bus cycle requirements.

Specialized ICS Part Context

This part belongs to the MC68882 family of floating-point co-processors. These devices were widely used in workstations and embedded systems during the late 1980s and 1990s to accelerate scientific and graphical calculations. The MC68882 is functionally similar to the MC68881 but may offer improved performance or integration features depending on the specific revision.
