7.5.2.4 Part Number Symbolization
Device part number symbolization information can be determined from the device-specific datasheet or
can be computed by reading locations in the TI OTP bank 0 registers.
For example the device part number symbolization "RM57L843ZWT" can be read from TI OTP bank 0
location F008 01E0h through F008 01FFh as shown in Figure 7-5. The part number is stored as a null
terminated ASCII string.

7.5.2.5 Temperature Sensor
There are three temperature sensors that can be used to read the internal junction temperature on this
device. The temperature sensors are connected to the ADC converter. See Section 6.5.13 for information
on how to select the temperature sensors. During device testing, the value read from the ADC along with
the junction temperature of the silicon was recorded in the OTP at three different temperatures. These
values can be read from TI OTP starting at location F008 0310h as shown in Figure 7-6 and described in
Table 7-8. The values recorded were measured with ADREFHI equal to 3.3V.
