Renesas Electronics Corporation Memory 70V3319S166BF8

The 70V3319S166BF8 is a high-speed dual-port synchronous static RAM from Quarktwin Technology Ltd., featuring a memory configuration of 256K x 18 bits. It operates at a core voltage of 3.3V (¬±150mV) and supports selectable I/O voltages of either 3.3V or 2.5V, making it versatile for various applications. The device is designed for high-speed performance, with maximum access times of 3.6ns at 166MHz and 4.2ns at 133MHz. It supports full synchronous operation on both ports, allowing simultaneous access to the same memory location, which is beneficial for applications requiring high data throughput. The memory supports pipelined or flow-through output modes, although the pipelined option is limited to certain package types. It includes features such as self-timed write capabilities, dual cycle deselect for pipelined output mode, and automatic power-down functionality to minimize power consumption during idle periods. The device is available in a 208-pin fine pitch Ball Grid Array (BGA) package and operates within an industrial temperature range of -40¬8C to +85¬8C. This product is suitable for applications that demand high-speed data access and dual-port functionality.
