nanoETXexpress-SP/Special Features

 4.7  Fast I2C

The nanoETXexpress-SP integrates two configurable I2C buses. The external I2C provided via US15W GPIOs on COM 
Express™ Connector Pin B33/B34, the LVDS I2C from US15W SCH is available on COM express™ connector pin 
A83/A84. The I2C interface offers full MultiMaster and Clock Stretching support. Fast I2C clock speed depends on the 
CPU performance and differs between ATOM™ Z510 and ATOM™ Z530 modules. See the tables below for measured 
values on nanoETXexpress-SP with BIOS NOW1R113.
