General Description
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.
Key Features
- 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.
- 1 Mbit/s and up to 25 mA SCL/SDA IOL (Fast-mode Plus (Fm+)) capability.
- I2C-bus General Call capability.
- Software reset on parallel bus.
- 68-byte data buffer.
- Operating supply voltage: 2.3 V to 3.6 V.
- 5 V tolerant I/Os.
- Standard-mode and Fast-mode I2C-bus.
