PCA9665A Product details

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.

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.
