FAQ

Q: STM8S207RBT6 vs. STM8S207CBT6 — which one?
A: Choose the CBT6 (LQFP-48) for single-motor CAN ESCs, simple BMS nodes, and space-constrained designs — 38 GPIOs are sufficient for most single-function CAN nodes. Choose the RBT6 (LQFP-64) when you need more than 38 GPIOs: dual-motor control, 8S BMS without analog multiplexers, or multi-function act

Q: Can the STM8S207RBT6 handle 12 PWM channels simultaneously?
A: Yes. The two advanced timers each provide 6 complementary PWM outputs (12 total) with independent dead-time insertion — sufficient for two 3-phase inverters. Alternatively, the advanced + general-purpose timers can generate up to 20+ independent PWM channels for servo control in complex actuator app

1. Product Overview

The STM8S207RBT6 in LQFP-64 takes the Performance Line's CAN-capable STM8 platform and maximizes I/O availability with 52 GPIOs and a 16-channel ADC . This package is the go-to choice when a CAN-connected drone node must control multiple motors, read numerous analog sensors, or drive complex actuator configurations — all from a single MCU with native CAN bus connectivity. In drone architectures, the RBT6 variant enables a single-chip dual-motor CAN ESC — driving two 3-phase inverters (12 gate-drive PWM channels) while communicating throttle and telemetry over CAN. For BMS applications, the 52 GPIOs and 16 ADC channels can directly monitor an 8S battery pack with individual cell voltage sensing, 4 temperature sensors, pack current, and charge/discharge FET control — all on one chip with CAN

2. Key Features

  • 52 GPIOs — Dual Motor + CAN + Full Sensor Suite
  • 16-Channel 10-Bit ADC — Direct 8S Cell Monitoring
