7285L12PAG - Renesas Electronics

Description: The 7285 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.

7285L12PAG Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (R01AN2732EU0100) which includes thermal design considerations, such as thermal vias, copper pours, and component placement, to ensure optimal thermal performance.
  • The 7285L12PAG has a built-in overcurrent protection feature that can be enabled by setting the OCP pin high. Additionally, an external sense resistor can be used to monitor the current and trigger an interrupt or shutdown when the current exceeds a certain threshold.
  • Renesas recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF, depending on the input voltage and operating frequency, to ensure stable operation and minimize voltage ripple.
  • The output voltage accuracy can be adjusted by trimming the internal voltage reference using the VREF pin. Renesas provides a trimming procedure in their application note (R01AN2732EU0100) to achieve ±1% output voltage accuracy.
  • The maximum allowed voltage on the enable pin is 6V, and it's recommended to use a voltage limiter or a resistor divider to ensure the voltage does not exceed this limit, especially when using a higher voltage supply.
