The STM704SM6F: The 2.925V threshold targets 3.0V or 3.3V rails where the supervisor must trip before the core voltage falls below the processor's minimum operating level. A 140ms minimum reset timeout gives the system power supply time to stabilise and the oscillator to start — common for MCUs that need tens of milliseconds to initialise their PLL and flash controller.
The STM704TM6F is the closest peer — same reset type (active low, push-pull), same 140ms minimum timeout, same 8-SOIC package and temperature range. The key difference is the threshold voltage: the TM6F variant uses a different trip point, so verify your rail voltage before substituting.
The reset timeout is a minimum of 140ms. This is the time the reset output stays asserted after the monitored supply rises above the 2.925V threshold.
