SLDU007C March 2012 – November 2015 PGA450-Q1
The OTP tab is set up only for individual register read/writes without the use of the grid. When this tab is displayed, the READ SELECTED / READ ALL and WRITE SELECTED / WRITE ALL buttons perform the same operations, respectively. The OTP tab also contains buttons used to load a .HEX 8051 program file into the 8051 MCU in the PGA450-Q1 device.
The PGA450Q1EVM could potentially have two devices: a device that is soldered on the EVM and a device that is in the socket. The GUI allows programming of either device. When the device choice is made, the GUI automatically resets the microprocessor for the respective device so that it is ready to load OTP through SPI
NOTE
The OTP program requires R2 to be populated and the VPWR:VOTP jumper to be installed. This connects the VPROG_OTP 8-V supply on the VP_OTP pin during programming. See the data sheet for more details.
