7164L35DB - 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.

7164L35DB Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (APL-AN-1163) for the 7164L35DB, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.
  • Renesas recommends using an external overcurrent protection circuit, such as a fuse or a dedicated overcurrent protection IC, to prevent damage to the device in case of an overcurrent event. The datasheet provides guidelines for selecting the appropriate overcurrent protection component.
  • Renesas recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF for the input capacitor, depending on the specific application requirements. The capacitor should be placed as close as possible to the device's input pins to minimize noise and ensure stable operation.
  • Renesas provides guidelines for EMC compliance in their application note (APL-AN-1164), which includes recommendations for PCB layout, component selection, and shielding to minimize electromagnetic interference (EMI) and ensure compliance with relevant EMC standards.
  • The 7164L35DB is rated for operation from -40°C to +125°C, but the maximum operating temperature range may vary depending on the specific application and environmental conditions. It's essential to consult the datasheet and application notes for specific guidance on temperature-related considerations.
