Product features
Doc ID 14395 Rev 5
5.5
Low-power operating modes
The product features various low-power modes:
●
Slow mode: prescaled CPU clock, selected peripherals at full clock speed
●
Active halt mode: CPU and peripheral clocks are stopped, the device cyclically goes
back to run mode, controlled by the AWU timer. Wakeup through external events is
possible.
●
Halt mode: CPU and peripheral clocks are stopped, the device remains powered on.
Wakeup is triggered by an external interrupt.
In all modes the CPU and peripherals remain permanently powered on, the system clock is
applied only to selected modules. The RAM content is preserved and the brown-out reset
circuit remains activated.
5.6
Interrupt controller
●
Nested interrupts with three software priority levels
●
24 interrupt vectors with hardware priority
●
Five vectors for external interrupts (up to 37 depending on the package)
●
Trap and reset interrupts
5.7
Input/output specifications
The product features four different I/O types:
●
Standard I/O 2 MHz
●
Fast I/O 10 MHz
●
High sink 8 mA, 2 MHz
●
True open drain (I2C interface)
To decrease EMI (electromagnetic interference), high sink I/Os have a limited maximum
slew rate. The rise and fall times are similar to those of standard I/Os.
The analog inputs are equipped with a low leakage analog switch. Additionally, the schmitt-
trigger input stage on the analog I/Os can be disabled in order to reduce the device standby
consumption.
STM8A I/Os are designed to withstand current injection. For a negative injection current of
4 mA, the resulting leakage current in the adjacent input does not exceed 1 A. Thanks to
this feature, external protection diodes against current injection are no longer required.
5.8
Timers
5.8.1
Watchdog timers
The watchdog system is based on two independent timers providing maximum security to
the applications. The watchdog timer activity is controlled by the application program or
option bytes. Once the watchdog is activated, it cannot be disabled by the user program
without going through reset.
