Renesas Electronics Corporation Memory 70V28L15PFG

The 70V28L15PFG is a high-speed 64K x 16 dual-ported static RAM designed for both commercial and industrial applications. It features true dual-ported memory cells, allowing simultaneous access to the same memory location from two independent ports. The device operates with a maximum access time of 15 ns for commercial applications and 20 ns for industrial applications, making it suitable for high-speed data processing. Power consumption is relatively low, with typical active power usage at 440 mW and standby power at 660 ¬µW. The memory supports depth expansion through dual chip enables, facilitating the creation of wider data buses without the need for additional external logic. It operates on a single 3.3V (¬±0.3V) power supply and is compatible with LVTTL logic levels. The 70V28L15PFG is packaged in a 100-pin TQFP, making it suitable for compact designs. It also includes features such as on-chip port arbitration logic and semaphore signaling support, enhancing its functionality in multi-processor systems. The device is available in both commercial (0¬8C to +70¬8C) and industrial (-40¬8C to +85¬8C) temperature ranges, catering to a variety of environmental conditions.
