PCU9669 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...
PCU9669 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
- 1 Mbit/s and up to 30 mA SCL/SDA IOL Fast-mode Plus (Fm+) capability
- Internal oscillator trimmed to 1 % accuracy reduces external ponents
- Individual 4352-byte buffers for the Fm+ and UFm channels for a total of 13056 bytes
- Three levels of reset: individual software channel reset, global software reset, global
- municates with up to 64 slaves in one serial sequence
- Sequence looping with interval timer
- Supports SCL clock stretching (Fm+ only)
- JTAG port available for boundary scan testing during board manufacturing process
