STM8TL52G4中文资料8位超低功耗触摸感应MCU，具有16-KB Flash和接近探测功能数据手册ST规格书

描述 Description

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.
