Power supply and power consumption
•General
–TX/RX can be as low as 14.7mA
–Low MCU current consumption (~250uA/MHz)
–Extremely low power sleep modes – as low as 0.5uA
•Optimized for coin cell CR2032
–Quick start-up – minimize duration of peak current consumption
–Minimum operating voltage of 2.0 V provides good resistance to dips in voltage supply
–Architecture allows 8051 core to operate independently from the radio keeping peak current as small as possible
•Good for alkaline as well
–Operating voltage range of 2.0 – 3.6 V matches dual AA
