Renesas Electronics Corporation Memory 70V3399S133PRFI8

The 70V3399S133PRFI8 is a high-speed dual-port synchronous static RAM with a capacity 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. The device features true dual-port memory cells, allowing simultaneous access to the same memory location from both ports, which is beneficial for applications requiring high data throughput. This memory chip supports a maximum access time of 4.2ns at 133MHz for industrial temperature ranges, with a cycle time of 6ns. It includes features such as self-timed write capabilities, separate byte controls, and dual chip enables for depth expansion. The device is available in multiple package options, including a 128-pin Thin Quad Flatpack and various Ball Grid Array configurations. The 70V3399S133PRFI8 is suitable for applications that require fast data access and low power consumption, with an industrial temperature range of -40°C to +85°C. It also supports JTAG features, although this is not available in the 128-pin TQFP package due to pin count limitations.
