Program memory is read-only from within firmware. Individual program memory bytes can be read using
the MOVC instruction. This facilitates the use of byte-programmable EPROM space for constant storage.
15.1.1. Derivative ID
To distinguish between individual derivatives in the C8051T620/1/6/7 & C8051T320/1/2/3 device family,
the Derivative ID is located at the address indicated in Figure 15.3 in EPROM memory. The Derivative ID
for the devices in the C8051T620/1/6/7 & C8051T320/1/2/3 are as follows:
15.1.2. Temperature Offset Calibration
The C8051T620/1/6/7 & C8051T320/1/2/3 devices include a factory calibrated temperature sensor offset
coefficient located in the EPROM memory. The TOFFH and TOFFL values are located at the address indi-
cated in Figure 15.3. More information on using the temperature sensor calibration values can be found in
Section “9.1. Calibration” on page 58.
15.1.3. Serialization
All C8051T620/1/6/7 & C8051T320/1/2/3 devices have a factory serialization located in EPROM memory.
This value is unique to each device. The serial number is located at the address indicated in Figure 15.3
and can be accessed like any constant array in program memory.
