STM8TL52G4:8-bit, ultra-low-power, touch-sensing MCUs with 16-Kbyte Flash and proximity detection

The STM8TL52x4 and STM8TL53x4 devices feature the 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. It uses a ProxSense charge transfer capacitive acquisition method that is capable of near range proximity detection.

The family includes an integrated debug module with a hardware interface (SWIM) which allows non-intrusive in-application debugging and ultrafast Flash programming. All STM8TL52x4 and STM8TL53x4 microcontrollers feature low-power low-voltage single-supply program Flash memory.

The STM8TL52x4 and STM8TL53x4 devices are based on a generic set of state-of-the-art peripherals. 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.
