SPECIFICATIONS
Typical (typ) is given for VS = 3.3 V, TA = 25°C, unless otherwise noted. Minimum (min) and maximum (max) values are given over full
VS (3.0 V to 3.6 V) and TA (40°C to +85°C) variation. AC coupling capacitors of 0.1 μF used where appropriate. A Fox Electronics
FX532A 25 MHz crystal is used throughout, unless otherwise stated.
