Deep sleep mode, switching off the LDO's

Sudarshan ns

1. Does DM 355 support deep power down mode with external LDO's power switched-off(for few VDD's) ?

2. If yes then I need to know what are the VDD can be powered-off with external LDO's and which is the pin used to switch -off the power?

Thanks

Sudarshan,

It doesn't support that type of mode, but if you put the device in deep sleep mode, the power consumption on the VDDs are very small. The only power consummed will be by the core vdd and digital I/O and if well I/O optimized for power consumption you are looking at sometying in the neighborhood of <5mW.

Please take a look at the following guidelines for optimizing power consumption on this device.
