PCU9669 - Parallel bus to 1 channel Fm+ and 2 channel UFm I2C-bus controller

General Description

The PCU9669 is an advanced single master mode I2C-bus controller.

It is a fourth generation bus controller designed for data intensive I2C-bus data transfers.

Key Features

  • Parallel-bus to I2C-bus protocol converter and interface.
  • 5 Mbit/s unidirectional data transfer on Ultra Fast-mode (UFm) channel (push-pull driver).
  • 1 Mbit/s and up to 30 mA SCL/SDA IOL Fast-mode Plus (Fm+) capability.
  • Internal oscillator trimmed to 1 % accuracy reduces external components.
  • Individual 4352-byte buffers for the Fm+ and UFm channels for a total of 13056 bytes of buffer space.
  • Three levels of reset: individual software channel reset, global software r.

PCU9669 Parallel bus to 1 channel Fm+ and 2 channel UFm I2C-bus controller Rev. 2 — 1 July 2011 Product data sheet 1. General description The PCU9669 is an advanced single master mode I2C-bus controller. It is a fourth generation bus controller designed for data intensive I2C-bus data transfers. It has three independent I2C-bus channels, one of them with data rates up to 1 Mbits/s using the Fast-mode Plus (Fm+) open-drain topology and two with a much larger transmit only transfer rate of up to 5 Mbits/s using the new Ultra Fast-mode (UFm) bus with push-pull topology. Each channel has a generous 4352 byte data buffer which makes the PCU9669 the ideal companion to any CPU that needs to transmit and receive large amounts of serial data with minimal interruptions.
