6.8 FRAM

The FRAM can be programmed through the JTAG port, Spy-Bi-Wire (SBW), the BSL, or in-system by the CPU. Features of the FRAM include:

• Low-power ultra-fast write nonvolatile memory
• Byte and word access capability
• Programmable and automated wait state generation
• Error correction coding (ECC) with single bit detection and correction, double bit detection

For important software design information regarding FRAM including but not limited to partitioning the memory layout according to application-specific code, constant, and data space requirements, the use of FRAM to optimize application energy consumption, and the use of the memory protection unit (MPU) to maximize application robustness by protecting the program code against unintended write accesses, see MSP430™ FRAM Technology – How To and Best Practices.
