PCA9665
Datasheet
General description
The PCA9665 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 can operate as a master or a slave and can be a transmitter or receiver. Communication with the I2C-bus is carried out on a Byte or Buffered mode using interrupt or polled handshake. The PCA9665 controls all the I2C-bus specific sequences, protocol, arbitration and timing with no external timing element required.
The PCA9665 has the same footprint as the PCA9564 with additional features:
- 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
- Parallel-bus to I2C-bus protocol converter and interface
- Both master and slave functions
- Multi-master capability
- Internal oscillator trimmed to 15 pct 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 capable and compatible with SMBus
- ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115, and 1000 V CDM per JESD22-C101
- Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
- Packages offered: DIP20, SO20, TSSOP20, HVQFN20

Applications
- Add I2C-bus port to controllers/processors that do not have one
- Add additional I2C-bus ports to controllers/processors that need multiple I2C-bus ports
- Converts 8 bits of parallel data to serial data stream to prevent having to run a large number of traces across the entire printed-circuit board
