CA9665A
Overview
The PCA9665/PCA9665A serves as an interface between most standard parallel-bus microcontrollers/microprocessors and the serial I2C-bus and allows the parallel bus system to communicate bidirectionally with the I2C-bus. The PCA9665/PCA9665A can operate as a master or a slave and can be a transmitter or receiver.
- 1 MHz transmission speeds
- Up to 25 mA drive capability on SCL/SDA
- 68-byte buffer
- I2C-bus General Call
- Software reset on the parallel bus
- Features and benefits
- Parallel-bus to I2C-bus protocol converter and interface
- Both master and slave functions
- Multi-master capability
- Internal oscillator trimmed to 15 % accuracy reduces external components
