71124S12YG - Renesas Electronics

Description: The 71124 5V CMOS SRAM is organized as 128K x 8. The JEDEC centerpower/GND pinout reduces noise generation and improves system performance. All bidirectional inputs and outputs of the 71124 are TTL-compatible and operation is from a single 5V supply. Fully static asynchronous circuitry is used; no clocks or refreshes are required for operation.

71124S12YG Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Ensure a minimum of 1mm clearance around the package for airflow.
  • Power up the device in the following sequence: VCC, AVCC, and then DVCC. Ensure a minimum delay of 10ms between each power-up step.
  • Use a series resistor (R1) of 1kΩ and a parallel capacitor (C1) of 10pF to 22pF. The crystal frequency should be 12MHz ± 0.5%.
  • Use a 10kΩ pull-up resistor and a 100nF capacitor to the reset pin. Ensure the reset signal is asserted for at least 10ms during power-up.
  • Use a shielded enclosure, ensure proper grounding, and add EMI filters to the power supply lines. Follow the Renesas application note for EMI reduction techniques.
