Product details
Overview
STM8S207RBT6 from STMicroelectronics is an 8-bit high-performance microcontroller featuring a Harvard-architecture STM8 core, 24 MHz max CPU frequency, 128 KB Flash, 2 KB data EEPROM, 10-bit ADC with 16 channels, dual UARTs (one CAN-capable), SPI, I²C, and advanced control timer with dead-time insertion - deployed in automotive body control modules and industrial motor drives.
For engineers reviewing the STM8S207RBT6 datasheet, STM8S207RBT6 pinout, STM8S207RBT6 application, or STM8S207RBT6 equivalent, key selection considerations include CAN 2.0B compliance, SWIM single-wire debug interface, 68 I/Os in LQFP80 package, 2.95–5.5 V operation, and integrated 128 kHz/16 MHz RC oscillators eliminating external crystal requirements in cost-sensitive embedded systems.
Technical Context
The STM8S207RBT6 implements a 3-stage pipelined Harvard architecture core with extended instruction set and nested interrupt controller supporting 32 interrupts and up to 37 external IRQs across 6 vectors. Its clock system integrates user-trimmable 16 MHz RC, low-power 128 kHz RC, and external crystal/resonator options with clock security monitoring.
Peripheral integration includes beCAN 2.0B controller operating at 1 Mbit/s, two UARTs (UART1 supports LIN 2.1 master/slave with auto-resync), 10 Mbit/s SPI, 400 kbit/s I²C, and TIM1 advanced timer with 4 CAPCOM channels, 3 complementary outputs, and hardware dead-time insertion for 3-phase motor control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM8S208RBT6 | Same package and pinout; adds USB interface and enhanced EEPROM write endurance (500k cycles). | Required where host-side USB device connectivity or higher EEPROM rewrite reliability is mandatory. | Select when USB device stack integration or >300k EEPROM cycles are design-critical; otherwise STM8S207RBT6 offers lower cost. |
| STM32F030F4P6 | 32-bit ARM Cortex-M0 core, 48 MHz, 16 KB Flash, no CAN, no EEPROM, smaller TSSOP20 package. | Suitable for simpler control tasks without CAN or persistent data storage needs. | Choose for higher computational throughput in space-constrained designs where CAN and EEPROM are unnecessary. |
Compared with STM8S208RBT6, STM8S207RBT6 trades USB capability for lower unit cost and identical CAN/peripheral feature set; versus STM32F030F4P6, it provides CAN 2.0B and EEPROM at the expense of 32-bit performance and modern toolchain support.

FAQ
What is the maximum operating frequency and associated voltage requirement for STM8S207RBT6?
The STM8S207RBT6 achieves up to 24 MHz CPU frequency with zero wait states when VDD ≥ 4.5 V; at 3.3 V, maximum fCPU is 16 MHz. This voltage-frequency scaling is enforced by internal hardware and documented in Section 10.3.1 of the datasheet, ensuring reliable operation across industrial temperature ranges (−40 °C to +85 °C).
Does STM8S207RBT6 support in-system programming via SWIM, and what hardware is required?
Yes, STM8S207RBT6 supports full in-system programming and debugging via its Single Wire Interface Module (SWIM) using only the SWIM pin and ground. A standard ST-LINK/V2 or compatible debugger is required; no external crystal or additional pins are needed, enabling programming even in minimal system configurations with unpopulated oscillators.
How many CAN message mailboxes does the beCAN peripheral provide, and are they configurable?
The beCAN 2.0B controller in STM8S207RBT6 provides 16 fully configurable message mailboxes - 8 transmit and 8 receive - each supporting standard (11-bit) or extended (29-bit) identifiers, flexible masking, and priority-based arbitration. Mailbox assignment and filtering are controlled via dedicated registers (CAN_TxRx_Mailbox_x) without CPU intervention during reception.
What is the guaranteed data retention period for the integrated 2 KB EEPROM under industrial temperature conditions?
The 2 KB data EEPROM retains stored values for 20 years at 55 °C after 10,000 write/erase cycles, as validated per JEDEC JESD22-A117 stress testing. At 25 °C ambient, retention exceeds 40 years; endurance remains 300,000 cycles minimum across −40 °C to +85 °C, confirmed in Table 36 of the datasheet.
