In order for the customer to extract meaningful information about devices such as flash size, SRAM size, package type, and temperature range, Texas Instruments has also revised the part numbering scheme for Tiva C Series devices. This only affects the Cortex M4 devices with part numbers starting with LM4F. If the customer has developed firmware with LM4F parts, please review the information on the screen for important changes from LM4F to TM4C.
