GENERAL DESCRIPTION
The XRP7704EVB-XPM is designed to allow
individuals to program the NVM (Non-Volatile
Memory) in the XRP7704, XRP7708, XRP7740,
and XRP7714.
The board consists of a microcontroller with on
board flash, pass fail indicators, a “push-to-
program” button, a TQFN40 socket, and a USB
port
programming parameters.
stored in the on board flash memory can be
changed through the use of Exar’s Digital
Power Studio available at Exar’s web site.
The firmware embedded in the microcontroller
validates the presence of the IC, ensures the
chip is able to be programmed to the desired
values, and then validates the data after the
write.
LED will illuminate on the board.
A USB Type A to Mini-B cable is required to
initially program this board.
The socket has an approximate life time of
1000 insertions.
Additional technical information and all related
documentation on Exar’s Power
