Description

The SC18IS601IBS is an electronic component model in the category of Network Interface Card (NIC). It serves as an interface between the standard SPI of a host and the serial I2C-bus, allowing direct communication with other I2C-bus devices. The SC18IS601IBS can function as an I2C-bus master-transmitter or master-receiver and controls all the I2C-bus specific sequences, protocol, arbitration, and timing. The key distinction between the SC18IS600 and the SC18IS601 lies in the clock source, with the SC18IS600 having an internal clock source and the SC18IS601 having an external clock source.

Application Scenarios

The SC18IS601IBS can be used in various applications where there is a need for communication between a host and I2C-bus devices. It is suitable for use in microcontrollers, microprocessors, chipsets, and any other device that requires I2C-bus communication interface.

Comparison

Advantages:

• Supports high-speed SPI
• Allows direct communication with I2C-bus devices
• Controls I2C-bus specific sequences, protocol, arbitration, and timing
• Available in a small TSSOP16 package

Disadvantages:

• The SC18IS601IBS has fewer GPIO pins compared to the SC18IS600
• The SC18IS600 has an internal clock source while the SC18IS601 requires an external clock source
