The IDT70T35/34L (IDT70T25/24L) is designed to be used as a stand-alone Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 36-bit (32-bit) or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic. This device provides two independent ports with separate control, address, and I/O pins that permit independent, asynchronous access for reads or writes to any location in memory. An automatic power down feature controlled by CEpermitstheon-chipcircuitryofeachporttoenter a very low standby power mode. Fabricated using IDT’s CMOS high-performance technology, these devices typically operate on only 200mW of power. The IDT70T35/34L (IDT70T25/24L) is packaged in a plastic 100-pin Thin Quad Flatpack and a 100-pin fine pitch Ball Grid Array. IDT70T35/34 Pin Configurations(1,2,3,4) NOTES: 1. A12 is a NC for IDT70T34. 2. All VDD pins must be connected to power supply. 3. All VSS pins must be connected to ground. 4. PN100-1 package body is approximately 14mm x 14mm x 1.4mm. 5.
