MCM32A732

This MCM32A732 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 autoconfiguration of the cache controller during system startup.
