Product Summary
The IDT70V28L15PF is a high-speed 64K × 16 Dual-Port Static RAM. The IDT70V28L15PF is designed to be used as a stand-alone 1024K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 32-bit-or-more word system. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 32-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic.
Parametrics
IDT70V28L15PF absolute maximum ratings: (1)VTERM, Terminal Voltage with Respect to GND: -0.5 to +4.6 V; (2)TBIAS, Temperature Under Bias: -55 to +125℃; (3)TSTG, Storage Temperature: -65 to +150℃; (4)IOUT, DC Output Current: 50 mA.
Features
IDT70V28L15PF 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)Dual chip enables allow for depth expansion without external logic; (5)IDT70V28 easily expands data bus width to 32 bits or more using the Master/Slave select when cascading more than one device; (6)M/S = VIH for BUSY output flag on Master, M/S = VIL for BUSY input on Slave; (7)Busy and Interrupt Flags; (8)On-chip port arbitration logic; (9)Full on-chip hardware support of semaphore signaling between ports; (10)Fully asynchronous operation from either port; (11)Separate upper-byte and lower-byte controls for multiplexed bus and bus matching compatibility; (12)LVTTL-compatible, single 3.3V (±0.3V) power supply; (13)Available in a 100-pin TQFP; (14)Industrial temperature range (–40 to +85℃) is available for selected speeds.
