The functional blocks of the controller are:
• DC Distribution
• Clock Sources
• Processor / Memory
• e-MMC Expandable Memory (expansion board)
• CPLD
• Audio – Internal and External
• MAKO
• User Interfaces
• RF Board Interface
• Type III Encryption Processor (expansion board)
• GPS/Bluetooth Combination IC (expansion board)

DC Distribution
SW_B+ supply comes from a pass FET (Q6501) that is powered by (battery voltage).
The FET is activated once the power switch is in its on position. SW_B+ supplies the power for the
entire controller. SW_B+ supplies MAKO and the external regulators. MAKO and the external
regulators then regulate the voltage to the desired level. (
See Figure 3-16.
)
OMAP's core is supplied by VCC_SW_1.4 (U6507). 1.85 LDO supplies OMAP's IO, FLASH, CPLD,
DDR, and MACE. See 3-4Table 3-4. for DC supplies and sources.
