Questions answered in these manuals
What is the specific requirement for using STMicroelectronics products in life support devices?
Use in life support devices or systems must be expressly authorized by STMicroelectronics.
What constitutes a critical component in a life support device or system?
A critical component is any component whose failure can reasonably be expected to cause the failure of the life support device or system, or to affect its safety or effectiveness.
How is the ST72251 woken up in this application?
The MCU is woken up by an external interrupt caused by a key press on the keypad.
What mode does the microcontroller enter to save power?
The microcontroller enters HALT mode, which is its lowest power consumption mode.
How many instructions does the ST7 instruction set have?
The ST7 instruction set contains 63 instructions.
