Working Principle

The MSP430FR2512IRHLT is based on a Harvard architecture, which enables simultaneous instruction fetching and data access so that both types of read and write operations can be complete in one clock cycle. It organises its Flash memory into 32K-word blocks, each 8-bits wide and begins executing instructions from the reset vector, which is located by default at location 0000h. The microcontroller also includes registers, which are used to store data that is used in arithmetic and logic operations. These registers are addressable, which means that the content of the register can be written or read using its address.

The microcontroller uses an RISC instruction set that is designed to optimize code size and execution speed. It uses 16-bit instructions, though some instructions are 32-bit and can do more than one operation in a single clock cycle. For example, the MOVA instruction can move 16-bit data from a register to an address in memory in a single instruction and cycle. This minimizes the number of clock cycles and memory fetches needed for a certain operation, resulting in faster execution and lower power consumption.

The integrated 16MB Serial Flash provides extended on-chip non-volatile memory. The Serial Flash memory is organized in 8K-word blocks, each 8-bits wide, and includes error correction blocks (ECC) to ensure data integrity. The Serial Flash also includes an integrated write cache, allowing it to write faster and with fewer power disruptions than standard Flash memories. Additionally, the Serial Flash can be operated in both standalone and co-processor mode, enabling more powerful applications.

Conclusion

The MSP430FR2512IRHLT is a powerful and versatile 16-bit MCU family for a wide range of low-power applications. Its integrated Flash memory and on-chip peripherals make it suitable for a wide range of application fields, ranging from consumer electronics to industrial automation and control.
