DSC 5681/5 IDT70X525XML Low Power 4K x 8 TriPort Static RAM Preliminary Industrial Temperature Range Description The IDT70X525X is a high-speed 8K x 16 TriPort Static RAM designed to be used in systems where multiple access into a common RAM is required. This TriPort Static RAM offers increased system performance in multiprocessor systems that have a need to communicate in real time and also offers added benefit for high-speed systems in which multiple access is required in the same cycle. The IDT70X525X is also designed to be used in systems where onchip hardware port arbitration is not needed. This part lends itself to those systems which cannot tolerate wait states or are designed to be able to externally arbitrated or withstand contention when more than one port simultaneously accesses the same TriPort RAM location. The IDT70X525X provides three independent ports with separate control, address, and I/O pins that permit independent, asynchronous access for reads or writes to any location in memory. It is the user's responsibility to ensure data integrity when simultaneously accessing the same memory location from mutiple ports. An automatic power down feature, controlled by BE0 and BE1 on Port 1 and CE on Port 2 and on Port 3, permits the on-chip circuitry of each port to enter a very low power standby power mode. The IDT70X525X is packaged in a 144-ball 0.5mm-pitch fpBGA.

These devices have an automatic power down feature controlled by BE0 and BE1 on Port 1 and CE on Port 2 and Port 3. The CE (or BEX) controls on-chip power down circuitry that permits the respective port to go into standby mode when not selected (CE or BEX = VIH). When Port 1 is enabled, it has access to the full memory. When Port 2 is active it has access to Bank 1 of the memory. When Port 3 is active it has access to Bank 2 of the memory.

Port 2's interrupt flag (INTP2 - P1) is asserted when Port 1 writes to memory location FFF (HEX), where a write is defined as BE0 = R/W = VIL. Port 2 clears the interrupt by accessing address location FFF when CE = VIL, R/W is a "don't care". Likewise, Port 3's interrupt flag (INTP3 - P1) is asserted when Port 1 writes to memory location FFF (HEX), where a write is defined as BE1= R/W = VIL. Port 3 clears the interrupt by accessing address location FFF when CE= VIL, R/ W is a "don't care". If the user chooses the interrupt function, a memory location (mailbox or message center) is assigned to each port. Interrupt P1 - P2 of Port 1 (INTP1 - P2) is asserted when Port 2 writes to memory location FFE(HEX), where a write is defined as CE = R/W = VIL per Truth Table II. Port 1 clears the interrupt by accessing address location FFE when BE0 = VIL, R/W is a "don't care".
