71T75802S200PFG - Renesas Electronics

Description: The 71T75802 2.5V CMOS Synchronous SRAM organized as 1M x 18 (18 Megabit). 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 Turnaround. The 71T75802 contains data I/O, address and control signal registers.

71T75802S200PFG Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (AP-6093) for the 71T75802S200PFG. 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 side of the PCB.
  • To ensure reliable operation in high-temperature environments, it's essential to follow Renesas' guidelines for thermal design and management. This includes using a heat sink, ensuring good airflow, and monitoring the device's junction temperature (Tj) to prevent overheating.
  • Renesas recommends using a low-ESR ceramic capacitor (X5R or X7R dielectric) for CIN, with a value between 4.7 μF to 10 μF. For COUT, a low-ESR ceramic or electrolytic capacitor with a value between 10 μF to 22 μF is recommended. The specific values depend on the output voltage and load requirements.
  • To optimize the feedback network, Renesas recommends using a resistive divider with a ratio of 1:1 to 1:2, and placing the feedback resistors close to the device. Additionally, a capacitor (CFB) in the range of 10 pF to 100 pF can be added in parallel with the feedback resistors to improve stability.
  • When paralleling multiple 71T75802S200PFG devices, it's essential to ensure that each device has its own input capacitor and output capacitor. Additionally, the devices should be matched in terms of output voltage and current rating, and the output tracks should be connected in parallel using a low-impedance path.
