The AT8xEB5114 has 3 software-selectable modes of reduced activity for further reduc-
tion in power consumption. In idle mode the CPU is frozen while the peripherals are still
operating. In quiet mode, only the A/D converter is operating. In power-down mode the
RAM is saved and all other functions are inoperative. Three oscillator sources, crystal,
precision RC and low power RC, provide versatile power management.
The AT8xEB5114 is available in low pin count packages (ROM and flash versions).
