71V546S133PFG - Renesas Electronics

Description: The 71V546 3.3V CMOS SRAM is organized as 128K x 36 bits. 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 Turn-around. The 71V546 contains data I/O, address and control signal registers. In the burst mode, it can provide four cycles of data for a single address presented to the SRAM.

71V546S133PFG Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (AP-6093) for the 71V546S133PFG. It suggests using a 4-layer PCB with a solid ground plane, placing the device near the edge of the board, and using thermal vias to improve heat dissipation.
  • Renesas recommends using a power sequencing controller, such as the ISL6123, to ensure proper power-up and power-down sequencing of multiple 71V546S133PFG devices. The controller can be programmed to meet specific power sequencing requirements.
  • While the datasheet specifies an operating temperature range of -40°C to 85°C, Renesas recommends derating the device's performance at temperatures above 70°C to ensure reliable operation. Consult the datasheet and application notes for specific derating guidelines.
  • The 71V546S133PFG is not specifically designed or tested for radiation-hardened applications. Renesas offers other products, such as the RH71V546S133PFG, which are designed for radiation-hardened applications and meet specific radiation tolerance requirements.
  • Renesas recommends using ESD protection devices, such as the NUP2105LQ, on the input and output pins of the 71V546S133PFG to prevent damage from electrostatic discharge. The protection devices should be selected based on the specific application requirements.
