M-Class M62xx Processor Cores

The MIPS M6200/M6250 processor cores are ideal for microcontroller and embedded-type applications.

The M62xx cores are superset extensions of the MIPS microAptiv family, being the first M-Class processors to implement the latest MIPS Release 6 Architecture.

The M6200 and M6250 implement a 6-stage pipeline design and continue to support both MIPS32 and microMIPS ISAs.

These new processor cores continue the M-Class line-up in offering both a microcontroller (MCU) and microprocessor (MPU) versions within the same family:

The M62xx family includes the following processor cores:

MIPS M6200

The MIPS M6200 features an integrated 64-bit SRAM controller, a memory protection unit, and a real-time, low-latency execution unit, optimized for cost-efficient, low-power microcontroller and embedded applications.

The M6200 and M6250 continue the evolution of the M-Class processors, offering improved performance and additional features from the microAptiv cores.
These cores provide a compelling solution for a wider range of applications requiring high operating frequency, increased memory throughout, data integrity support
