7164S25YGI - Renesas Electronics

Description: The 7164 5V CMOS SRAM is organized as 8K x 8. The 7164 offers a reduced power standby mode. The low-power (L) version also offers a battery backup data retention capability at power supply levels as low as 2V. All inputs and outputs of the IDT7164 are TTL-compatible and operation is from a single 5V supply, simplifying system designs. Fully static asynchronous circuitry is used, requiring no clocks or refreshing for operation. Military grade product is available.

7164S25YGI Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (APL-AN-116) for the 7164S25YGI, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.
  • To ensure reliable operation in high-temperature environments, it's essential to follow Renesas' recommended thermal design guidelines, use a suitable heat sink, and consider derating the device's power consumption according to the temperature derating curve provided in the datasheet.
  • Renesas recommends using a low-ESR ceramic capacitor (CIN) with a value between 1-10uF and a voltage rating of at least 2x the input voltage. For COUT, a low-ESR ceramic capacitor with a value between 1-22uF and a voltage rating of at least 1.5x the output voltage is recommended.
  • To troubleshoot issues with the EN pin, ensure that it is properly connected to a logic-level signal (e.g., 3.3V or 5V) and that the signal is not floating. Also, verify that the EN pin is not being driven by a signal with excessive slew rate or ringing, which can cause the device to malfunction.
  • Not using the recommended external components can lead to reduced performance, instability, or even device failure. The recommended components are specified to ensure the device operates within its intended specifications, so omitting or substituting them can compromise the device's reliability and functionality.
