71256S70DB - Renesas Electronics

Description: The 71256 5V CMOS SRAM is organized as 32K x 8. The circuit also offers a reduced power standby mode for significant system level power and cooling savings. The low-power (L) version also offers a battery backup data retention capability allowing operation off a 2V battery. Fully static asynchronous circuitry is used; no clocks or refreshes are required for operation. Military grade product is available.

71256S70DB Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the 71256S70DB is -40°C to +125°C.
  • To ensure reliable data transmission, ensure that the transmission lines are properly terminated, and the signal integrity is maintained by following the recommended PCB layout guidelines and using suitable transmission line impedance.
  • The maximum clock frequency supported by the 71256S70DB is 100 MHz.
  • To ensure proper power sequencing, power up the VCCIO and VCC cores simultaneously, and ensure that the power supply voltage is stable before applying the clock signal.
  • Use a 0.1 μF ceramic capacitor and a 10 μF electrolytic capacitor in parallel, placed as close as possible to the power pins, to ensure proper power supply decoupling.
