Memory
1 - 10 C2000 Microcontroller Workshop - Architecture Overview
The user OTP is a one-time, programmable, memory block. TI reserves a small space in the map
for the ADC and oscillator calibration data. The flash block contains a section for passwords,
which are used by the code security module. The boot ROM and boot ROM vectors are located
at the bottom of the memory map.

valuable intellectual property
128-bit user defined password is stored in Flash
128-bits = 2

= 3.4 x 10
38
possible passwords
To try 1 password every 8 cycles at 80 MHz, it would
take at least 1.1 x 10
24
years to try all possible
combinations!
