Product overview
STM8TL5xxx
3.2 Development tools
Development tools for the STM8 microcontrollers include:
The ST-Link very low-cost professional tool to debug and program
The STVD high-level language debugger including C compiler, assembler and
integrated development environment
The STVP Flash programming software
The STM-STUDIO real-time and non-intrusive graphical interface used to probe
application variables and data
The STM8 also comes with starter kits, evaluation boards and low-cost in-circuit
debugging/programming tools.
3.3 Single wire data interface (SWIM) and debug module
The debug module with its single wire data interface (SWIM) permits non-intrusive real-time
in-circuit debugging and fast memory programming.
The Single wire interface is used for direct access to the debugging module and memory
programming. The interface can be activated in all device operation modes.
The non-intrusive debugging module features a performance close to a full-featured
emulator. Beside memory and peripherals, also CPU operation can be monitored in real-
time by means of shadow registers.
3.4 Interrupt controller
The STM8TL5xxx features a nested vectored interrupt controller:
Nested interrupts with 3 software priority levels
22 interrupt vectors with hardware priority
Up to 22 external interrupt sources on 10 vectors
TRAP and RESET interrupts
3.5 Memory
The STM8TL5xxx devices have the following main features:
4 Kbytes of RAM
The EEPROM is divided into two memory arrays (see the STM8TL5xxx reference
manual (RM0312) for details on the memory mapping):
– 16 Kbytes of low-density embedded Flash program including up to 2 Kbytes of
data EEPROM. Data EEPROM and Flash program areas can be write protected
independently by using the memory access security mechanism (MASS).
– 64 option bytes (one block) of which 5 bytes are already used for the device.
– Error correction code is implemented on the EEPROM.
