MOTOROLA SEMICONDUCTOR TECHNICAL DATA Advance Information 128KB/256KB Secondary Cache Module With Tag, Valid, and Dirty for i486 Processor Systems This family of cache modules is well suited to provide the secondary cache for the Intel 82420 PCI chipset. This family provides the 128K Byte and 256K Byte cache sizes with valid, dirty and a choice of 7, 8, or 9 tag bits. The tag/valid bits have 12 ns access times for zero wait states at 33 MHz clock speeds. The PD pins map into the configuration register of the 82420 for auto–configuration of the cache controller during system startup.
