TMS320F2800137: Which function to be used for disabling clock of the peripheral in tms320f28e12 controller?

shweta kulkarni

In 132, there is function " Device_enableAllPeripherals();" This function has all the clocks peripherals can be disabled, where i can also seperately disable the specific peripheral clock. IN 28e12 controller, there is no function like this available only "

SysCtl_enablePeripheral(SYSCTL_PERIPH_CLK_TBCLKSYNC);" how can i disable other clocks like sci, adc, ecap?

There is no PERCLKCRx register for F28e12x. These are directly connected to SYSCLK.

okay, but how i can disable this , i want to achieve <1w when controller is in standby mode for my application,

Hi Shweta,

The power consumption data is available in section 6.4 of the datasheet. In standby mode with PLL enabled the maximum current consumption is < 16.5mA at 85C. This is less than 55mW. In standby mode the SYSCLK and the CPUCLK are gated so all the other peripherals are gated as well.
