71V3558S133PFGI - Renesas Electronics

Description: The 71V3558 3.3V CMOS Synchronous SRAM is organized as 256K x 18. It is designed to eliminate dead bus cycles when turning the bus around between reads and writes, or writes and reads. Thus, it has been given the name ZBTTM, or Zero Bus Turnaround. The 71V3558 contains data I/O, address and control signal registers.

71V3558S133PFGI Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (Renesas Document No. AP-5053) which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
  • A reliable POR circuit can be implemented using an external voltage supervisor IC (such as the Renesas ISL88003) that monitors the power supply voltage and asserts a reset signal to the 71V3558S133PFGI during power-up and power-down sequences.
  • The 71V3558S133PFGI has a maximum junction temperature (Tj) of 150°C. To ensure reliable operation, it's essential to implement proper thermal management, such as using a heat sink, thermal interface material, and optimizing the PCB layout to minimize thermal resistance.
  • The 71V3558S133PFGI is not specifically designed or tested for radiation-hardened applications. If radiation hardness is required, Renesas offers other products that are designed and tested for such applications, such as the RH3578S133PFGI.
  • Renesas provides a JTAG debugging guide (Renesas Document No. AP-5055) that includes troubleshooting tips and guidelines for using the JTAG interface to debug and test the 71V3558S133PFGI.
