PCA9665 PCA9665A 2 Fm+ parallel bus to I C-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 2 microcontrollers/microprocessors and the serial I C-bus and allows the parallel bus 2 system to communicate bidirectionally with the I C-bus. The PCA9665/PCA9665A can operate as a master or a slave and can be a transmitter or receiver. Communication with 2 the I C-bus is carried out on a Byte or Buffered mode using interrupt or polled handshake. 2 The PCA9665/PCA9665A controls all the I C-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 2 I C-bus General Call Software reset on the parallel bus 2. Features and benefits 2 Parallel-bus to I C-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 I (Fast-mode Plus (Fm+)) capability OL 2 I C-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 2 Standard-mode and Fast-mode I C-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: TSSOP20PCA9665 PCA9665A NXP Semiconductors 2 Fm+ parallel bus to I C-bus controller 3. Applications 2 Add I C-bus port to controllers/processors that do not have one 2 2 Add additional I C-bus ports to controllers/processors that need multiple I C-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 4.
