Product Summary
The IDT70V25S15PF is a dual-port static RAM. The IDT70V25S15PF is a high-speed 8K x 16 Dual-Port Static RAM. The IDT70V25 is designed to be used as a stand-alone Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 32-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic. The IDT70V25S15PF 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 CE permits the on-chip circuitry of each port to enter a very low standby power mode.
Parametrics
IDT70V25S15PF absolute maximum ratings: (1)Terminal Voltage with Respect to GND : -0.5 to +4.6 V; (2)Temperature Under Bias : -55 to +125 ℃; (3)Storage Temperature : -55 to +125 ℃; (4)DC Output Current : 50 mA.
Features
IDT70V25S15PF features: (1)True Dual-Ported memory cells which allow simultaneous reads of the same memory location; (2)Separate upper-byte and lower-byte control for multiplexed bus compatibility; (3)IDT70V25 easily expands data bus width to 32 bits or more using the Master/Slave select when cascading more than one device; (4)On-chip port arbitration logic; (5)Full on-chip hardware support of semaphore signaling between ports; (6)Fully asynchronous operation from either port; (7)LVTTL-compatible, single 3.3V (±0.3V) power supply; (8)Available in 84-pin PGA, 84-pin PLCC and 100-pin TQFP; (9)Industrial temperature range (-40℃ to +85℃) is available for selected speeds.
