PCA9560D,118

Specialized Overview

The PCA9560D,118 is a 20-pin CMOS device featuring two 6-bit non-volatile EEPROM registers, five hardware pin inputs, and a 5-bit multiplexed output with one latched EEPROM bit. It supports Mobile and Desktop VID Configuration for processor voltage settings in performance or sleep modes. Operating power supply voltage ranges from 3.0 V to 3.6 V, with I/O tolerant to 5 V and 2.5 V. The clock frequency operates between 0 Hz and 400 kHz. ESD protection exceeds 2000 V HBM and 1000 V CDM. Memory retention is guaranteed for at least 10 years with 100,000 write cycles minimum.

Specialized Feature Summary

• Dual 6-bit internal non-volatile EEPROM registers enabling three independent preset values for system configuration
• 5-bit 3-to-1 multiplexer allowing selection between external hardware pins and internal non-volatile registers
• I2C/SMBus interface logic with active high write protect input controlling register access
• Fully pin-to-pin compatible drop-in replacement for the PCA9559 without software modifications

Specialized Applications

• Mobile and Desktop CPU VID (Voltage IDentification code) configuration
• Server and telecom/networking applications replacing DIP switches or jumpers
• System configuration requiring performance, deep sleep, or deeper sleep mode voltage settings

Specialized Procurement Notes

Verify the ordering part number PCA9560PW,118 matches the required TSSOP20 package type. Confirm the operating temperature range of -40 °C to +85 °C aligns with your environmental specifications. Ensure the 3.0 V to 3.6 V supply voltage requirement fits your system design constraints before finalizing procurement.

Specialized Selection Notes

Select this component when a drop-in replacement for the PCA9560 is needed with dual non-volatile registers instead of single register variants like the PCA9559. It is suitable for designs requiring hardware pin inputs alongside programmable EEPROM storage. Verify that the I2C bus address pins A0 and A1 can accommodate up to four devices on the same bus line.

Specialized Part Context

This device belongs to the NXP Semiconductors family of I2C-bus EEPROM DIP switches. It serves as an evolution of the PCA9559 by adding a second non-volatile register, allowing for more complex voltage configurations. The component is designed specifically for bridging CPUs and Voltage Regulator Modules to bypass standard VID values.

Specialized Replacement Considerations

The PCA9560 is a direct footprint-compatible replacement for the PCA9559. No software modifications are required for this substitution. Ensure the target application utilizes only two non-volatile registers or leaves Register 1 at all zeros if mimicking PCA9559 behavior via MUX_SELECT_1.

Specialized FAQ

How does the PCA9560 differ from the PCA9559?

The PCA9560 contains two internal non-volatile EEPROM registers compared to the single register in the PCA9559. This allows for three independent settings (performance, deep sleep, deeper sleep) instead of two.

Can the multiplexer selection be overridden?

Yes, the multiplexer selection can be overridden by the I2C-bus. Additionally, the MUX_SELECT_1 pin can function as an override pin similar to the PCA9559 if Register 1 is left at all zeros.

What is the data retention period for the non-volatile memory?

The non-volatile memory cell data retention is specified for a minimum of 10 years.
