71V256SA12YG8 - Renesas Electronics

Description: The 71V256SA 3.3V CMOS Asynchronous SRAM is organized as 32K x 8. When in standby mode, its very low power characteristics contribute to extended battery life. Under full standby mode (CS at CMOS level, f=0), power consumption is guaranteed to be less than 6.6mW. Fully static asynchronous circuitry is used; no clocks or refreshes are required for operation.

71V256SA12YG8 Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the 71V256SA12YG8 is 3.3V ± 0.3V, but it can operate from 2.7V to 3.6V with some performance degradation.
  • It's recommended to power up the VCCQ pin (output driver power) before the VCC pin (core power) and power down the VCC pin before the VCCQ pin to prevent latch-up and ensure proper operation.
  • The maximum clock frequency supported by the 71V256SA12YG8 is 133 MHz, but it can operate at lower frequencies with reduced power consumption.
  • A reliable reset circuit can be implemented using a voltage supervisor IC or a simple RC circuit with a diode to ensure a clean reset signal and prevent latch-up during power-up.
  • The 71V256SA12YG8 has a maximum junction temperature of 150°C. To ensure reliable operation, it's essential to provide adequate heat sinking, use thermal interface materials, and follow proper PCB design guidelines to minimize thermal resistance.
