Product Introduction

Overview

The PCA9513AD,112 is a hot swappable I²C-bus and SMBus buffer produced by NXP USA Inc. This component is designed to facilitate the insertion and removal of I/O cards into a live backplane without corrupting the data and clock buses. It is part of the PCA9513A and PCA9514A family, which enhances the reliability and functionality of I²C and SMBus applications.

Key Features

  • Hot Swappable: Allows I/O card insertion into a live backplane without data corruption.
  • Bidirectional Buffering: Isolates backplane and card capacitances, ensuring reliable communication.
  • Rise Time Accelerator: Enables the use of weaker DC pull-up currents while meeting rise time requirements.
  • Current Source: Provides a 92 µA current source on SCLIN and SDAIN for consistent RC time constants.
  • ENABLE and READY Pins: Digital ENABLE input and open-drain READY output for device control and status indication.
  • Support for Clock Stretching and Multiple Master Arbitration: Enhances I²C and SMBus protocol compliance.

Applications

  • cPCI, VME, AdvancedTCA Cards: Suitable for multipoint backplane cards that require insertion or removal from an operating system.
  • Multidrop Bus Applications: Ideal for applications where cards are frequently added or removed from the backplane.
  • Industrial and Embedded Systems: Used in various industrial and embedded systems requiring reliable I²C and SMBus communication.

Q & A

  1. What is the primary function of the PCA9513AD,112?

    The primary function is to act as a hot swappable I²C-bus and SMBus buffer, allowing I/O card insertion into a live backplane without corrupting the data and clock buses.

  2. What is the operating voltage range of the PCA9513AD,112?

    The operating voltage range is 2.7 V to 5.5 V.

  3. What is the maximum clock frequency supported by the PCA9513AD,112?

    The maximum clock frequency is 400 kHz.

  4. Does the PCA9513AD,112 have built-in ESD protection?

    Yes, it exceeds 2000 V HBM, 200 V MM, and 1000 V CDM.

  5. What is the purpose of the 92 µA current source on SCLIN and SDAIN?

    The 92 µA current source provides consistent RC time constants in multidrop bus applications.

  6. How does the ENABLE pin function on the PCA9513AD,112?

    The digital ENABLE input pin enables the device when asserted HIGH and forces it into a low current mode when asserted LOW.

  7. What is indicated by the READY output pin?

    The READY output pin indicates whether the backplane and card sides are connected (HIGH) or not (LOW).
