12 / 100 page program, specific code libraries, reset and interrupt vectors, the reset routine and usually the IAP and communication routines. Figure 2: Flash memory organization UBC area Program memory area Remains write protected during IAP Write access possible for IAP Option bytes Programmable bytes(1 page) up to 8 Kbytes (in 1 page steps) area from 64 Low density Flash program memory (8 Kbytes) Data EEPROM (128 bytes) Read-out protection (ROP) The read-out protection blocks reading and writing from/to the Flash program memory and the data EEPROM in ICP mode (and debug mode). Once the read-out protection is activated, any attempt to toggle its status triggers a global erase of the program memory. Even if no protection can be considered as totally unbreakable, the feature provides a very high level of protection for a general purpose microcontroller. Clock controller 4.5 The clock controller distributes the system clock (fMASTER) coming from different oscillators to the core and the peripherals. It also manages clock gating for low power modes and ensures clock robustness. Features • Clock prescaler: To get the best compromise between speed and current consumption the clock frequency to the CPU and peripherals can be adjusted by a programmable prescaler. • Safe clock switching: Clock sources can be changed safely on the fly in run mode through a configuration register. The clock signal is not switched until the new clock source is ready. The design guarantees glitch-free switching. • Clock management: To reduce power consumption, the clock controller can stop the clock to the core, individual peripherals or memory. • Master clock sources: Four different clock sources can be used to drive the master clock: - 1-16 MHz high-speed external crystal (HSE) - Up to 16 MHz high-speed user-external clock (HSE user-ext) - 16 MHz high-speed internal RC oscillator (HSI) - 128 kHz low-speed internal RC (LSI) DocID018576 Rev 3 12/100 STM8S003K3 STM8S003F3 Product overview |
