PCA9564BS,118

Controllers Overview

The PCA9564BS,118 is a parallel bus to I2C-bus controller manufactured by NXP Semiconductors. It operates within a supply voltage range of 2.3 V to 3.6 V and features 5 V tolerant I/Os. The device supports standard and fast mode I2C communication with SMBus compatibility. It includes an internal oscillator that reduces external component requirements. The IC provides both master and slave functions with multi-master capability. It utilizes interrupt or polled handshake for byte-wise communication. The component is housed in a 20-pin HVQFN package.

Controllers Feature Summary

• Parallel-bus to I2C-bus protocol converter and interface
• Internal oscillator reduces external components
• Both master and slave functions with multi-master capability
• ESD protection exceeds 2000 V HEM per JESD22-A114

Controllers 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
• Higher frequency, lower voltage migration path for the PCF8584
• Converts 8 bits of parallel data to serial data stream to prevent having to run a large number of traces across the entire PC board

Controllers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check for obsolescence notices as Philips Semiconductors product data sheets may indicate end-of-life status. Ensure ordering suffixes match specific package requirements. Validate technical specifications against current datasheets before integration.

Controllers Selection Notes

Select this component when interfacing standard parallel buses with I2C systems requiring bidirectional communication. Consider the 2.3 V to 3.6 V operating voltage range for low-power applications. Evaluate the internal oscillator feature to minimize external timing components. Assess the need for master/slave capabilities and multi-master support. Verify pin compatibility if replacing legacy devices like the PCF8584.

Controllers Part Context

The PCA9564 series serves as an interface between parallel bus microcontrollers and the serial I2C-bus. It allows parallel bus systems to communicate bi-directionally with I2C devices. The device controls all I2C-specific sequences, protocol, arbitration, and timing without external timing elements. It is designed in CMOS technology for reliable operation in various embedded systems.

Controllers Replacement Considerations

The PCA9564 is not footprint compatible with the PCF8584. While similar in function, it operates at lower voltages and higher frequencies. Code compatibility is not guaranteed due to design differences from Philips standard 80C51 microcontroller I2C hardware. Verify electrical parameters and pin configurations before substitution.
