Product overview

Description

The medium-density value line STM8L052C6 devices are members of the STM8L ultra-low-power 8-bit family.

The value line STM8L05xxx ultra-low-power family features 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.

The family includes an integrated debug module with a hardware interface (SWIM) which allows non-intrusive In-application debugging and ultra-fast Flash programming.

Medium-density value line STM8L052C6 microcontrollers feature embedded data EEPROM and low-power, low-voltage, single-supply program Flash memory.

All devices offer 12-bit ADC, real-time clock, 16-bit timers, one 8-bit timer as well as standard communication interface such as SPI, I2C, USART and 4x28-segment LCD. The 4x 28-segment LCD is available on the medium-density value line STM8L052C6.

The STM8L052C6 operates from 1.8 V to 3.6 V and is available in the -40 to +85 °C temperature range.

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.

All value line STM8L ultra-low-power products are based on the same architecture with the same memory mapping and a coherent pinout.
