STM8S903K3T6CDescription
The STM8S903K3 and STM8S903F3 8-bit microcontrollers offer 8 Kbytes Flash program
memory, plus integrated true data EEPROM. The STM8S microcontroller family reference
manual (RM0016) refers to devices in this family as low-density. They provide the following
benefits: performance, robustness, and reduced system cost.
Device performance and robustness are ensured by advanced core and peripherals made
in a state-of-the art technology, a 16 MHz clock frequency, robust I/Os, independent watchdogs
with separate clock source, and a clock security system.
The system cost is reduced thanks to an integrated true data EEPROM for up to 300
kwrite/erase cycles and a high system integration level with internal clock oscillators, watchdog
and brown-out reset.
Full documentation is offered as well as a wide choice of development tools.
STM8S903K3T6CUnique ID
The devices feature a 96-bit unique device identifier which provides a reference number that
is unique for any device and in any context. The 96 bits of the identifier can never be altered
by the user.
The unique device identifier can be read in single bytes and may then be concatenated using
a custom algorithm.
The unique device identifier is ideally suited:
• For use as serial numbers
• For use as security keys to increase the code security in the program memory while using
and combining this unique ID with software cryptograhic primitives and protocols before
programming the internal memory.
• To activate secure boot processes
