Product Summary
The IDT70V27L15PFG is a high-speed 32K x 16 Dual-Port Static RAM. The IDT70V27L15PFG is designed to be used as a stand-alone 512K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 32-bit and wider word systems. 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. The IDT70V27L15PFG 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
IDT70V27L15PFG 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:-65℃ to +150℃; (4)DC Output Current:50 mA.
Features
IDT70V27L15PFG features: (1)True Dual-Ported memory cells which allow simultaneous access of the same memory location; (2)High-speed access:Industrial: 35ns (max.),Commercial: 15/20/25/35/55ns (max.); (3)Low-power operation:Active: 500mW (typ.),Standby: 660μW (typ.); (4)Separate upper-byte and lower-byte control for bus matching capability; (5)Dual chip enables allow for depth expansion without external logic; (6)IDT70V27S/L; (7)IDT70V27 easily expands data bus width to 32 bits or more using the Master/Slave select when cascading more than one device; (8)M/S = VIH for BUSY output flag on Master,M/S = VIL for BUSY input on Slave; (9)Busy and Interrupt Flags; (10)On-chip port arbitration logic; (11)Full on-chip hardware support of semaphore signaling between ports; (12)Fully asynchronous operation from either port; (13)LVTTL-compatible, single 3.3V (±0.3V) power supply; (14)Available in 100-pin Thin Quad Flatpack (TQFP), 108-pin Ceramic Pin Grid Array (PGA), and 144-pin Fine Pitch BGA(fpBGA); (15)Industrial temperature range (-40℃ to +85℃) is available for selected speeds.
