PCU9661 Overview
The PCU9661 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 a transmit only transfer rate of up to 5 Mbits/s using the new Ultra Fast-mode (UFm) bus with push-pull topology.
PCU9661 Key Features
- Parallel-bus to I2C-bus protocol converter and interface
- 5 Mbit/s unidirectional data transfer Ultra Fast-mode (UFm) channel (push-pull driver)
- Internal oscillator trimmed to 1 % accuracy reduces external ponents
- 4352-byte UFm channel buffer
- Three levels of reset: software channel reset, global software reset on parallel bus
- municates with up to 64 slaves in one serial sequence
- Sequence looping with interval timer
- JTAG port available for boundary scan testing during board manufacturing process
- Trigger input synchronizes serial munication exactly with external events
- Maskable interrupts
