Step 2.
Connect the TI GER board to the PC.
Step 3.
Open the PGA450Q1EVM GUI.
Step 4.
Click the
OFF (Micro Reset)
button on the ESFR tab.
Step 5.
Click the
READ ALL
button to read all registers on the ESFR tab. Use register B4
(TEMP_SENS) as an indicator to ensure the device is operating and communicating properly
through SPI. Proper communication can be verified if the data of the register reads a value
other than 0x00 or 0xFF.
Step 6.
Under the OTP tab, click
Check OTP Status
button. If the PGA450-Q1 device has not been
previously been OTP programmed, the status displays
OTP Empty
.
Step 7.
Connect the 8-V supply to the VPROG_OTP pin on the sensor to program the OTP memory,
to program the DEVRAM memory for the first time, or if the OTP status displays
OTP Empty
.
Step 8.
If programming DEVRAM memory, go to the DEVRAM tab. For a pristine IC that has never
been programmed (OTP status displays
OTP Empty
), check the
Program OTP Memory Also
box for the GUI. This option programs both the OTP and DEVRAM memory. The OTP
memory will be programmed with a long-jump statement to redirect the firmware to load into
and be run from the DEVRAM memory. If programming OTP memory for production release
or a permanently coded PGA450-Q1 device, go to the OTP tab, click
Load .HEX File into
GUI
, and locate the appropriate OTP-based .HEX file.
Step 9.
Programming and verification of the device occurs automatically.
Step 10. When the device is verified, disconnect the VPROG_OTP supply voltage (if applicable). Do
not disconnect system supply voltage if DEVRAM has been programmed, because the
DEVRAM memory will clear when the PGA450-Q1 device is power cycled.
