FAQ
What is the maximum operating frequency and associated voltage range for STM8S207MBT6B?
The STM8S207MBT6B operates at up to 24 MHz fCPU with zero wait states when VDD ≥ 3.8 V; at 16 MHz, it supports the full 2.95–5.5 V range. Electrical characteristics confirm stable operation down to 2.95 V at 16 MHz, making it suitable for wide-input industrial power supplies.
Does STM8S207MBT6B support in-circuit debugging without dedicated debug headers?
Yes - it features the Single Wire Interface Module (SWIM), enabling full debugging and programming through a single dedicated pin (SWIM). No JTAG/SWD header or additional pins are required, simplifying PCB layout and reducing connector costs.
How many CAN message objects does the integrated beCAN controller support?
The beCAN controller supports 16 transmit/receive mailboxes with programmable priority and automatic message ID filtering. It implements full CAN 2.0B protocol handling including error framing, automatic retransmission, and bus-off recovery - all managed in hardware without CPU intervention.
What is the guaranteed endurance and data retention specification for the on-chip EEPROM?
The 2 KB data EEPROM is specified for 300,000 write/erase cycles and guarantees 20 years of data retention at 55 °C after 10,000 cycles. Retention is validated per JEDEC JESD22-A117, and endurance testing follows JESD22-A112 - confirmed in ST's production qualification reports.
