INTEGRATED CIRCUITS PCA9564 Parallel bus to I2C-bus controller Product data Supersedes data of 2003 Feb 26 2003 Apr 02 Philips Semiconductors Philips Semiconductors Product data Parallel bus to I2C-bus controller DESCRIPTION The PCA9564 is an integrated circuit designed in CMOS technology that serves as an interface between most standard parallel-bus microcontrollers/microprocessors and the serial I2C-bus and allows the parallel bus system to municate bi-directionally with the I2C-bus. The PCA9564 can operate as a master or a slave and can be a transmitter or receiver. munication with the I2C-bus is carried out on a byte-wise basis using interrupt or polled handshake. The PCA9564 controls all the I2C-bus specific sequences, protocol, arbitration and timing with no external timing element required. Features - Parallel-bus to I2C-bus protocol converter and interface - Both master and slave functions - Multi-master capability - Internal oscillator reduces external ponents - Operating supply voltage 2.3 V to 3.6 V - 5 V tolerant I/Os - Standard and fast mode I2C capable and patible with SMBus - ESD protection exceeds 2000 V HEM per JESD22-A114, 200 V MM per JESD22-A115, and 1000 V CDM per JESD22-C101 The PCA9564 is similar to the PCF8584 but operates at lower voltages and higher I@C frequencies. Other enhancements requested by design engineers have also been incorporated.
