2. General Description
FS8806/FS8826 is a companion chip with a solution to authenticate the embedded software license
right at the embedded system. It provides a simple and easy solution to implement authentication
mechanism in an embedded system. Just connect FS8806/FS8826 with host CPU via I2C or SPI and
add pieces of concerto software in original run-time software, then a secure system is ready. The
authentication for the embedded software (ESW) license is also very easy. The ESW failed to run in the
customer board without FS8806/FS8826 companion or the unmatched FS8806/FS8826 connected
with customer board. Two application configurations are shown as below:

SPI Mode Selection
FS8806/FS8826 will operate in I2C mode by default. SPI mode will be entered by receiving 3 rising
pulses on SS_N pin after hardware reset. The waveform is shown as below. It will still enter SPI mode
if more than 3 rising pulses on SS_N is detected. It is suggested to connect SS_N to power or ground
when operating in I2C mode. This serial interface operation mode will be reset only by hardware reset
and it will not be changed by software reset.
