Corelis has added direct I2C and SPI-based device programming capabilities for the ScanExpress Boundary-Scan System that employs JTAG controllers. SPI and I2C interfaces are independent of the JTAG test interface; the user can use the same JTAG controller to test the board and perform direct programming of serial EEPROM and flash memories without removing the JTAG connector or switching to a dedicated SPI and I2C programmer.
 
The user needs only to enable the direct programming option on the Test Programming file Generator (ScanExpressTPG) to create the SPI and I2C programming files. The programmer automatically detects the file type and programs the device using either the SPI protocol or the I2C.
 
Serial FLASH/EEPROM devices can be programmed at speeds up to the device theoretical programming time. This typically 10 times faster than programming the devices indirectly using JTAG. Programming capability allows versatile I2C and SPI device access.
 
Customers can upgrade their old controllers to include the new direct programming feature.
