PCA9665D Overview
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. The PCA9665/PCA9665A can operate as a master or a slave and can be a transmitter or receiver.
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
