Program and Data Memory

The MCU program code resides in the program memory.

'Beetle' Program memory is 16Mbits (1024kx 16bit) Flash memory. 'Scarap' Program memory is 8Mbits (512k x 16bit) Flash memory.

The flash memory has a power down pin, which is kept low, during the power up phase of the flash to ensure that the device is powered up in the correct state, read only. The power down pin is utilized in the system sleep mode by connecting the ExtSysResetX to the flash power down pin to minimize the flash power consumption during the sleep.
