True FourPort memory cells which allow simultaneous access of the same memory locations Fully asynchronous operation from each of the four ports: P1, P2, P3, P4 Versatile control for write-inhibit: separate BUSY input to control write-inhibit for each of the four ports Battery backup operation—2V data retention x x x x TTL-compatible; single 5V (±10%) power supply Available in 120 pin and 132 pin Thin Quad Flatpacks and 108 pin PGA Military product compliant to MIL-PRF-38535 QML Industrial temperature range (–40°C to +85°C) is available for selected speeds Description The IDT7052 is a high-speed 2K x 8 FourPort™ Static RAM designed to be used in systems where multiple access into a common RAM is required. This FourPort 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 IDT7052 is also designed to be used in systems where on-chip hardware port arbitration is not needed. This part lends itself to those Functional Block Diagram R/WP1 CEP1 OEP1 I/O0P1-I/O7P1 BUSYP1 PORT 1 ADDRESS DECODE LOGIC PORT 2...
