STM8AL318x STM8AL3L8x

Description

The high-density STM8AL3x8x ultra-low-power devices feature an enhanced STM8 CPU

core providing increased processing power (up to 16 MIPS at 16 MHz) while maintaining the

advantages of a CISC architecture with improved code density, a 24-bit linear addressing

space and an optimized architecture for low-power operations.

The family includes an integrated debug module with a hardware interface (SWIM) which

allows non-intrusive in-application debugging and ultrafast Flash programming.

All high-density STM8AL3x8x microcontrollers feature embedded data EEPROM and low-

power low-voltage single-supply program Flash memory.

The devices incorporate an extensive range of enhanced I/Os and peripherals, a 12-bit

ADC, two DACs, two comparators, a real-time clock, 8x40 or 4x44-segment LCD, four 16-bit

timers, one 8-bit timer, as well as standard communication interfaces such as two SPIs, an

I2C interface, and three USARTs. One 8x40 or 4x44-segment LCD is available on the

STM8AL3L8x devices. The modular design of the peripheral set allows the same

peripherals to be found in different ST microcontroller families including 32-bit families. This

makes any transition to a different family very easy, and simplified even more by the use of

a common set of development tools.
