280x devices have a richer peripheral mix compared to the 281x family. While the McBSP has been
removed, the following new peripherals have been added on the 280x:
3 SPI modules
1 CAN module
1 I
2
C module
The two event manager modules of the 281x have been enhanced and replaced with separate ePWM (6),
eCAP (4) and eQEP (2) modules, providing tremendous flexibility in applications. Like 281x, 280x DSPs
incorporate a unique method to reduce the device current consumption. Since each peripheral unit has an
individual clock-enable bit, significant reduction in current consumption can be achieved by turning off the
clock to any peripheral module that is not used in a given application. Furthermore, any one of the three
low-power modes could be taken advantage of to reduce the current consumption even further.
Table 6-4
indicates the typical reduction in current consumption achieved by turning off the clocks.
