70V658S12BCI - 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

70V658S12BCI 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 70V658S12BCI has an internal POR and BOD circuit. To implement POR, connect the VCC pin to a power supply with a suitable decoupling capacitor. For BOD, connect the VCC pin to a voltage detector circuit with a suitable threshold voltage. Refer to the datasheet and application notes for more details.
  • The maximum clock frequency for the 70V658S12BCI is 12 MHz. However, the actual clock frequency may vary depending on the system design, clock source, and operating conditions. It's essential to consult the datasheet and application notes for specific guidance.
  • To configure the 70V658S12BCI for low-power operation, use the power-down mode (PD) and idle mode (IDLE). These modes can be controlled through software by setting the corresponding bits in the power management control register. Refer to the datasheet and application notes for more information.
  • Renesas recommends using a crystal oscillator circuit with a suitable crystal resonator and load capacitors. The datasheet provides a recommended oscillator circuit diagram and component values. It's essential to follow these guidelines to ensure stable and accurate clock operation.
