ABSTRACT:
A microcontroller includes an electrically erasable and programmable nonvolatile memory and a memory controller for controlling the nonvolatile memory. Upon writing a control program for the microcontroller and data into the nonvolatile memory pursuant to an externally provided NVM command or an internally issued program command, a CPU of the microcontroller does not intervene in controlling the nonvolatile memory. Particularly, in a programming mode set by the external program command, CPU, buses, and communication interfaces of the microcontroller are deactivated. Further, the memory controller receives a NVM command, an address and data from outside of the microcontroller for controlling an operation of the nonvolatile memory based on the NVM command and the address without intervention of the CPU.
