= 3.0 V to 3.6 V unless otherwise specified.
Parameters are valid over operating temperature range unless otherwise specified. Parts are tested to 2 MHz, but are guaranteed to
operate down to 0 Hz.
When using an oscillator frequency above 12 MHz, the reset input function of P1.5 must be enabled. An external circuit is required to
hold the device in reset at power-up until V
minimum specified operating voltage. When using an oscillator frequency above 12 MHz, in some applications, an external brownout
detect circuit may be required to hold the device in reset when V
= 40 C to +85 C for industrial, unless otherwise specified.
