Board Layout
The Smart Tag evaluation board assembly top view is shown in Figure 2. The resistors for memory selection are
highlighted in red.
Figure 2: Board Assembly (Top View)
By default, the board is set to use the internal LPO for sleep, but it can be set to use external LPO by installing
R102 and R103, highlighted in Figure 2, above. Resistor values are listed in Table 1, below.
By default, the board is set to use EEPROM but can be set for serial flash by adjusting the resistors highlighted
in Figure 2 to the desired setting (shown in Table 2).
