7164S25YG8 - 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.

7164S25YG8 Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (APN) documents, which can be found on their website. The guide includes recommendations for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
  • The 7164S25YG8 has a built-in overcurrent protection feature. However, to implement it, you need to connect an external resistor (Roc) between the OC pin and GND. The value of Roc determines the overcurrent threshold. Refer to the datasheet for the calculation formula and recommended values.
  • Although the datasheet specifies a maximum operating voltage of 25V, the VIN pin can tolerate up to 30V during startup for a short duration (typically 100ms). However, it's essential to ensure that the voltage does not exceed 25V during normal operation.
  • The output voltage can be adjusted by connecting a resistor divider network between the VOUT pin and GND. The ratio of the resistors determines the output voltage. Refer to the datasheet for the calculation formula and recommended values.
  • Although the datasheet specifies a minimum input voltage of 6.5V, the device can operate down to 6.2V with reduced performance. However, it's recommended to maintain a minimum input voltage of 6.5V for optimal performance and reliability.
