PCA9564PW,112

The PCA9564PW,112 is an integrated circuit designed by NXP Semiconductors that acts as a parallel bus to I2C-bus protocol converter and interface. It allows parallel bus systems to communicate bi-directionally with the I2C-bus, enabling controllers without an I2C port to add one or systems needing multiple ports to expand their capabilities.

This controller supports both master and slave functions, with multi-master capability. It features an internal oscillator, reducing the need for external components. The operating supply voltage ranges from 2.3 V to 3.6 V, with 5 V tolerant I/Os. It is capable of standard and fast mode I2C communication and is compatible with SMBus. The maximum I2C frequency in master mode is 360 kHz, and in slave mode, it is 400 kHz.

ESD protection exceeds 2000 V (HBM), 200 V (MM), and 1000 V (CDM). Latch-up testing exceeds 100 mA per JEDEC Standard JESD78. The PCA9564PW,112 is offered in a 20-TSSOP package and operates within a temperature range of -40°C to 85°C.

This device is suitable for applications requiring the addition of an I2C-bus port to microcontrollers or processors that lack one, or for expanding the number of available I2C-bus ports. It also serves as a higher frequency, lower voltage migration path from older controllers like the PCF8584.
