72V83L20PAGI - Renesas Electronics

Description: The 72V83 is a dual-FIFO memory that loads and empties data on a first-in/first-out basis. It utilizes a 9-bit wide data array to allow for control and parity bits at the user's option. This is useful in data communications applications where a parity bit is needed for transmission/reception error checking. It is designed for those applications requiring asynchronous and simultaneous read/writes in multiprocessing and rate buffer applications.

72V83L20PAGI Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (R01AN3601EJ0100) which includes thermal vias, copper pours, and component placement guidelines to ensure optimal thermal performance.
  • The 72V83L20PAGI has a built-in overcurrent protection feature. However, to implement it, you need to connect an external resistor (Roc) between the OC pin and GND. The value of Roc determines the overcurrent threshold. Refer to the datasheet for the calculation formula and recommended values.
  • Although the datasheet specifies a maximum operating voltage of 72V, the VIN pin can tolerate up to 80V during startup (t < 100ms) without damage. However, it's recommended to keep the voltage within the specified operating range for reliable operation.
  • To ensure a stable state during power-up, make sure to follow the recommended power-up sequence: 1) Apply VIN, 2) Wait for the internal voltage regulator to stabilize (t > 10ms), and 3) Apply EN (enable) signal. This sequence ensures the internal circuitry is properly initialized.
  • Renesas recommends using a TVS (Transient Voltage Suppressor) diode or a dedicated ESD protection IC, such as the Renesas RClamp0524P, to protect the 72V83L20PAGI from electrostatic discharge.
