board layout practices should be followed to reduce the chance
of uncontrolled laser drive current caused from a leakage path
between RBIN and ground. One hypothetical source of such a
leakage path is PC board contamination due to a liquid, such as a
soft drink, being deposited on the printed circuit board.

External PROM
The ADNS-6010 must operate from externally loaded
programming. This architecture enables immediate
adoption of new features and improved performance
algorithms. The external program is supplied by Avago
Technologies as a file, which may be burned into a pro-
grammable device. The example application shown in
this document uses an EEPROM to store and load the
external program memory. A micro-controller with suf-
ficient memory may be used instead. On power-up and
reset, the ADNS-6010 program is downloaded into vola-
tile memory using the burst-mode procedure described
in the Synchronous Serial Port section. The program size
is 1986 x 8 bits.
