... PowerPC is a trademark of IBM Corporation. Cypress Semiconductor Corporation Document #: 38-05140 Rev. ** The CY7C1327B I/O pins can operate at either the 2.5V or the 3.3V level. The I/O pins are 3.3V tolerant when V and PowerPC™ All synchronous inputs pass through input registers controlled by the rising edge of the clock ...

... Max- imum access delay from the clock rise (t device). The CY7C1327B supports secondary cache in systems utiliz- ing either a linear or interleaved burst sequence. The inter- leaved burst order supports Pentium and i486 processors. The linear burst sequence is suited for processors that utilize a linear burst sequence ...

... Because the CY7C1327B is a common I/O device, the Output Enable (OE) must be deasserted HIGH before presenting data to the DQ and DP inputs. Doing so will three-state the [15:0] [1:0] output drivers safety precaution, DQ automatically three-stated whenever a write cycle is detected, regardless of the state of OE. Single Write Accesses Initiated by ADSC ...
