The display subsystem also supports NTSC/PAL video out. Level 3 (L3) and level 4 (L4) interconnects that provide high-bandwidth data transfers for multiple initiators to the internal and external memory controllers and to on-chip peripherals The device also offers:
A comprehensive power and clock-management scheme that enables high-performance, low-power operation, and ultralow-power standby features. The device also supports SmartReflex? adaptative voltage control. This power management technique for automatic control of the operating voltage of a module reduces the active power consumption. Memory stacking feature using the package-on-package (POP) implementation (CBB and CBC packages only) OMAP3503 is available in a 515-pin s-PBGA package (CBB suffix), 515-pin s-PBGA package (CBC suffix), and a 423-pin s-PBGA package (CUS suffix). Some features of the CBB and CBC packages are not available in the CUS package.
Table 1-1 lists the differences between the CBB, CBC, and CUS packages.
