70V38L20PFGI8 - Renesas Electronics

Description: The 70V38 is a high-speed 64K x 18 Dual-Port Static RAM designed to be used as a stand-alone 576K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 36-bit or more word systems. This MASTER/SLAVE approach in 36-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic. An automatic power down feature controlled by Chip Enable (CE) permits the on-chip circuitry of each port to enter a very low standby power mode.

70V38L20PFGI8 Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (APL-AN-1201) for the 70V38L20PFGI8, which includes thermal vias, heat sink recommendations, and PCB layer stack-up suggestions.
  • The 70V38L20PFGI8 has built-in POR and BOD circuits. To implement them, connect the POR pin to a capacitor and a resistor to VCC, and the BOD pin to a capacitor and a resistor to VCC. Refer to the datasheet for specific values and configuration guidelines.
  • The maximum allowed clock skew is not explicitly stated in the datasheet. However, as a general guideline, it's recommended to keep the clock skew below 1 ns to ensure reliable operation. Consult with Renesas support or a clock domain expert for specific guidance.
  • The 70V38L20PFGI8 is not specifically designed or qualified for radiation-hardened or high-reliability applications. If you need a radiation-hardened or high-reliability device, consider Renesas' QML-V (Qualified Manufacturers List - V) or QML-Q (Qualified Manufacturers List - Q) certified products.
  • Renesas provides a troubleshooting guide in their application note (APL-AN-1202) for the 70V38L20PFGI8, which covers common issues, debugging techniques, and fault isolation methods. Additionally, consult the datasheet and contact Renesas support for further assistance.
