Product overview

Description

The high-density STM8L162x8 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 STM8L162x8 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, AES, 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. 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.
