STM8L152C8U6 Description

In order to maintain the benefits of a CISC architecture with improved code density, a 24-bit linear addressing space, and optimized architecture for low-power operations, the high-density and medium+ density STM8L152C8U6 ultra-low-power device includes an enhanced STM8 CPU core. This core increases processing power (up to 16 MIPS at 16 MHz).

The family has an integrated debug module with a hardware interface (SWIM) that enables rapid Flash programming and non-intrusive in-application debugging.

All STM8L152C8U6 high-density and medium+ density microcontrollers have low-power, low-voltage single-supply program Flash memory and embedded data EEPROM.

A 12-bit ADC, two DACs, two comparators, a real-time clock, four 16-bit timers, one 8-bit timer, and a number of common communication interfaces, including three USARTs, two SPIs, and an I2C interface, are all included in the devices. The STM8L152C8U6 gadget comes with an 8x40 or 4x44-segment LCD. The peripheral set's modular construction enables the use of the same peripherals across many ST microcontroller families, including 32-bit generations. This makes switching to a new family quite simple, and using a standard set of development tools makes it much simpler.
