70V3379S4PRFG - Renesas Electronics

Description: The 70V3379 is a high-speed 32K x 18 bit synchronous Dual-Port RAM that has been optimized for applications having unidirectional or bidirectional data flow in bursts. An automatic power down feature, controlled by CE0 and CE1, permits the on-chip circuitry of each port to enter a very low standby power mode. The 70V3379 can support an operating voltage of either 3.3V or 2.5V on one or both ports, controllable by the OPT pins. The power supply for the core of the device (VDD) is at 3.3V.

70V3379S4PRFG Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the 70V3379S4PRFG is -40°C to 85°C, as specified in the datasheet.
  • The power-up sequence for the 70V3379S4PRFG should follow the recommended sequence in the datasheet, which is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization and prevents damage to the device.
  • The maximum clock frequency supported by the 70V3379S4PRFG is 133 MHz, as specified in the datasheet. However, it's essential to consider the system's overall timing budget and signal integrity when operating at higher frequencies.
  • The reset signal for the 70V3379S4PRFG should be asserted low for at least 10 ns to ensure a proper reset. The reset signal should also be synchronized with the clock signal to prevent metastability issues.
  • The recommended termination scheme for the 70V3379S4PRFG's output signals is to use a 50-ohm termination resistor to VCC or VDD, depending on the specific output signal. This helps to reduce signal reflections and improve signal integrity.
