Hi, I have an application which requires a MCU to run as a timer, powered by a battery. Please could anyone help with any information about low power modes on the teensy boards and how to set low power operation from code. I appreciate it's potentially a difficult question to answer without knowing more about the application, but essentially it's as follows: The mcu runs a timer and at a preset time a digital pin is set low to activate a MOSFET which switches on DC power to other equipment (it's a telescope and ancilliary devices in a remote observatory, powered by batteries). At another preset time, the MCU timer again activates the MOSFET to switch off the DC power.
Typically the MOSFET on time is around 6 p.m. and the off time is around 5 a.m., so the MCU spends most of its time as a timer.
The MCU itself will be run from a battery, so low power consumption is really helpful. I'm thinking 0.3 mA or less if possible.
If you need any further info, please let me know.
Thanks very much for help,
Paul
