485Turbocache Module

This document provides a technical data sheet for the Intel 485Turbocache Module, a performance upgrade designed for 25 MHz and 33 MHz i486 microprocessor systems. It details the module's 2-way set-associative architecture, its configuration as a 64k or 128k cache using 113-pin modules, and its operational features such as zero-waitstate access and parity bit monitoring. The document covers functional descriptions of read/write cycles, invalidation mechanisms, system configuration options (single, multiple, and optional cache setups), pin descriptions, mechanical specifications, and detailed A.C./D.C. characteristics.
