The STM8S is now available in two product lines, one focusing on performance (Performance Line) and one for general purpose applications (Access Line). Both lines share a common set of peripherals which include at least one SPI, I2C, and UART, an advanced 16-bit timer plus at least one other 16-bit and 8-bit timer, two watchdog timers, an Automatic Wake Up unit (AWU), a 16-bit ADC, internal high speed and low speed RC oscillators and a Single Wire interface Debug Module. The Access Line runs at up to 16 MHz with up to 2 KB SRAM, 1 KB EEPROM and 32 KB Flash. The Performance Line runs up to 24 MHz with additional peripherals which include a second UART, CAN, and larger memories of up to 6 KB SRAM, 2 KB EEPROM and 128 KB Flash.
