Device operating range is 2.7V - 5.5V. DC Electrical specifications are for operation 2.7V - 3.3V. 1. All voltages are referenced to ground. 2. Active mode current is measured with an 18 MHz clock source driving XTAL1, VCC=RST=3.3V, all other pins disconnected. 3. Idle mode current is measured with an 18 MHz clock source driving XTAL1, VCC=3.3V, all other pins disconnected. 4. Stop mode current measured with XTAL1 and RST grounded, VCC=3.3V, all other pins disconnected. |
