8-bit MCU with 24 MHz core and integrated EEPROM
The STM8S207M8T6BTR is an 8-bit microcontroller from STMicroelectronics' STM8S series, built around the STM8 core running at 24 MHz. Typical uses include motor control, sensor hubs, industrial I/O modules, and appliance control boards where the peripheral set—I²C, SPI, UART/USART, LIN, IrDA, plus 16-channel 10-bit ADC and PWM—covers most of the connectivity and analog needs without external glue.
Memory and peripheral headroom for control-loop designs
The 2 KB EEPROM, rated for 300k erase/write cycles typical, is useful for storing calibration tables, configuration parameters, or fault logs without wear-leveling overhead. The 68 general-purpose I/Os, combined with the 16-channel 10-bit ADC and the timer/counter peripherals (including PWM and a watchdog timer), give the designer enough headroom for a sensor-fusion node or a simple motor drive without needing an external ADC or EEPROM.
Package and footprint: 80-pin LQFP
Housed in an 80-pin LQFP package with a 14x14 mm body (0.5 mm pitch), the STM8S207M8T6BTR is a surface-mount device that fits standard LQFP-80 land patterns. The 68 I/Os are distributed around all four sides, which simplifies PCB routing for dense designs.
