17. Supply Controller (SUPC)
17.1
6257A–ATARM–20-Feb-08
Overview
The Supply Controller (SUPC) controls the supply voltages of the system. In a typical applica-
tion, the Supply Controller allows supply of the device directly from a double NiMH or NiCd
battery or from a double CR2031 Lithium battery or from any Lithium rechargeable battery.
The Supply Controller offers a wide range of Low Power Modes, including:
• Off Mode, current consumption reduced to below 1 microamp, exits on the assertion of the
• Backup Mode, current consumption reduced to a few microamps for Clock and SRAM
• Running Mode, reaches a 30-MIPS performance level
Force Wake Up pin (FWUP)
retention, exits on multiple wake-up sources
