Description:The 5962-88662 (71256 SRAM) is organized as 32K x 8. This part offers a reduced power standby mode for significant system level power and cooling savings. Fully static asynchronous circuitry is used; no clocks or refreshes are required for operation.
Renesas provides a recommended PCB layout guide in their application note (APL-AN-1201) for thermal management. It suggests using a 4-layer PCB with a solid ground plane, placing thermal vias under the package, and using a thermal pad on the bottom of the package.
Renesas recommends following their thermal design guidelines, using a heat sink or thermal interface material, and ensuring good airflow around the device. Additionally, consider using a thermistor or temperature sensor to monitor the device temperature and implement thermal throttling or shutdown if necessary.
Renesas recommends following their power sequencing guidelines, which typically involve ramping up the power supplies in a specific order (e.g., VCC, then VDD, then AVCC). The voltage ramp-up rate should be controlled to avoid overshoots and ensure a stable power-on reset.
Renesas provides guidelines for EMI and EMC in their application notes. Key recommendations include using a shielded enclosure, minimizing trace lengths and loop areas, using decoupling capacitors, and implementing EMI filters or common-mode chokes as needed.
Renesas recommends following their clock signal integrity guidelines, which include using a low-jitter clock source, minimizing clock signal trace lengths, and using clock signal conditioning circuits or buffers as needed. The device's clock input tolerance is typically specified in the datasheet.
