Overview
PCA9665; PCA9665A Fm+ parallel bus to I2C-bus controller Rev.
4 — 29 September 2011 Product data sheet 1.
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.
The PCA9665/PCA9665A 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/PCA9665A controls all the I2C-bus specific sequences, protocol, arbitration and timing with no external timing element required.
The PCA9665 and PCA9665A have 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 2.
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  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  PCA9665A ‘glitch-free’ restart is suitable for use with buffer drivers  ESD protection exceeds 2000 V HBM per JESD22-A114 and 1000 V CDM per JESD22-C101  Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA  Packages offered:  PCA9665: SO20, TSSOP20, HVQFN20  PCA9665A: TSSOP20 NXP Semiconductors PCA9665; PCA9665A Fm+ parallel bus to I2C-bus controller 3.
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 ...
