The recommended operating voltage range for the ST1S10PHR is 2.5V to 5.5V.
To ensure proper power-on and power-off, it is recommended to follow a power-up sequence of VCC first, then VIO, and power-down sequence of VIO first, then VCC.
The maximum clock frequency supported by the ST1S10PHR is 100 MHz.
The JTAG interface on the ST1S10PHR is compatible with IEEE 1149.1 standard. It is recommended to use a JTAG adapter and follow the standard JTAG protocol for debugging and programming.
The reset pin on the ST1S10PHR is an active-low input that resets the device when pulled low. It is recommended to connect a 10kΩ pull-up resistor to VCC and a 100nF capacitor to GND for proper reset operation.
