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°C to +70°C) and industrial (-40°C to +85°C) temperature ranges, catering to a variety of environmental conditions.
