70V658S15BC - Renesas Electronics

Description: The 70V658 is a high-speed 64K x 36 Asynchronous Dual-Port Static RAM designed to be used as a stand-alone Dual-Port RAM or as a combination MASTER/ SLAVE Dual-Port RAM for 72-bit-or-more word system. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 72-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 the chip enables (either CE0 or CE1) permit the on-chip circuitry of each por

70V658S15BC Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application notes (e.g., AN9834) and design guides (e.g., DG0034). It's essential to follow these guidelines to ensure optimal performance, minimize noise, and reduce electromagnetic interference (EMI).
  • The 70V658S15BC has a thermal pad on the bottom of the package. Ensure good thermal contact between the thermal pad and a heat sink or a thermal land on the PCB. Use thermal interface material (TIM) if necessary. Follow Renesas' thermal design guidelines and consider using thermal simulation tools to optimize your design.
  • The input clock signal should be a stable, low-jitter clock with a frequency range of 10-133 MHz. The clock signal should be AC-coupled and have a peak-to-peak amplitude of 2.5 V. Ensure the clock signal meets the specified jitter and duty cycle requirements in the datasheet.
  • The 70V658S15BC has an internal POR and BOD circuit. Connect a capacitor between the VCC pin and the POR/BOD pin to set the reset threshold. The recommended capacitor value is 10 nF. Ensure the power supply ramp-up time is within the specified range to prevent false resets.
  • Follow Renesas' EMC and EMI guidelines in their application notes and design guides. Ensure proper PCB layout, use shielding, and implement filtering and decoupling to minimize EMI. Consider using EMI simulation tools to optimize your design.
