The demonstration board consists of battery protection provided by the STBP120, which

protects the battery from undervoltage and overvoltage. The L6924D is used for proper

battery charging. The STBB1 converts battery voltage based on a preset slide switch

position and switching power on/off for the application. The STM660x smart supervisor

controls power management based on the position of both slide switches. A dual color

display indicates either proper functionality (blue backlight) or a frozen application (red

backlight). See also the block diagram in Figure 22.

Interposer

An interposer with the STM660x part can be easily plugged into a breadboard, soldered, or

effectively used with an evaluation board (see below), etc.

A breadboarded interposer can be easily measured or connected to the rest of the

application.

It is also much easier to solder wires to an interposer for any necessary external connection.

An interposer combined with an evaluation board provides flexibility, allowing various parts

to be changed quickly in the socket.
