Product Summary
The IDT7025S20PFI is a high-speed 8K x 16 Dual-Port Static RAM, which is designed to be used as a stand-alone 128K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 32-bit or more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 32-bit or wider memory system applications results in fullspeed, error-free operation without the need for additional discrete logic. The IDT7025S20PFI 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.
Parametrics
IDT7025S20PFI maximum ratings: (1)Terminal Voltage with Respect to GND: –0.5 to +7.0, –0.5 to +7.0 V; (2)Operating Temperature: 0 to +70℃, –55 to +125 ℃; (3)Temperature Under Bias: –55 to +125℃, –65 to +135℃; (4)Storage Temperature: –55 to +125℃, –65 to +150 ℃; (5)DC Output: 50 mA.
Features
IDT7025S20PFI features: (1)True Dual-Ported memory cells which allow simultaneous access of the same memory location; (2)High-speed access; (3)Low-power operation; (4)Separate upper-byte and lower-byte control for multiplexed bus compatibility; (5)Busy and Interrupt Flags; (6)On-chip port arbitration logic; (7)Full on-chip hardware support of semaphore signaling between ports; (8)Fully asynchronous operation from either port; (9)Battery backup operation-2V data retention; (10)TTL-compatible, single 5V (±10%) power supply.
