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:
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 5-5 indicates the typical reduction in current consumption achieved by turning off the clocks.
PERIPHERAL
MODULE |
IDD CURRENT
REDUCTION (mA)(2) |
---|---|
ADC | 8(3) |
I2C | 5 |
eQEP | 5 |
ePWM | 5 |
eCAP | 2 |
SCI | 4 |
SPI | 5 |
eCAN | 11 |
NOTE
IDDIO current consumption is reduced by 15 mA (typical) when XCLKOUT is turned off.
NOTE
The baseline IDD current (current when the core is executing a dummy loop with no peripherals enabled) is 110 mA, typical. To arrive at the IDD current for a given application, the current-drawn by the peripherals (enabled by that application) must be added to the baseline IDD current.
