8.4 Memory

The 256 KB nonvolatile (Flash) memory provides storage for code and data. The flash memory is in-system programmable and erasable. A special flash memory sector must contain a Customer Configuration section (CCFG) that is used by boot ROM and TI provided drivers to configure the device. This configuration is done through the ccfg.c source file that is included in all TI provided examples.

The ultra-low leakage system static 28 KB RAM (SRAM) can be used for both storage of data and execution of code. Retention of SRAM contents in Standby power mode is enabled by default and included in Standby mode power consumption numbers. System SRAM is always initialized to zeroes upon code execution during boot.

The ROM includes device bootcode firmware handling initial device trimming operations, security configurations and device lifecycle management. The ROM also contains a serial (SPI and UART) bootloader that can be used for initial programming of the device.
