Renesas Electronics Corporation Memory 70V25S15J8

The 70V25S15J8 is a high-speed dual-ported static RAM memory device from Quarktwin Technology Ltd., featuring a configuration of 8/4K x 16 bits. It supports simultaneous reads and writes from two independent ports, allowing for asynchronous access to any memory location. The device operates with a maximum access time of 15 ns for commercial applications and 20 ns for industrial applications. Power consumption is relatively low, with typical active power usage around 400 mW and standby power at approximately 3.3 mW. The memory is designed to be compatible with a single 3.3V power supply and is available in a 100-pin TQFP package. It also includes features such as on-chip port arbitration logic and full hardware support for semaphore signaling between ports, making it suitable for complex memory system applications. The device is available in both commercial and industrial temperature ranges, with the industrial version rated from -40¬8C to +85¬8C. Engineers considering this product should note its capability for expanding data bus width and its low power operation, which may be beneficial for applications requiring efficient memory solutions.
