STMicroelectronics STM8S207S6T6CTR

Overview

STM8S207S6T6CTR from STMicroelectronics is an 8-bit high-performance microcontroller featuring a Harvard-architecture STM8 core, 24 MHz max CPU frequency, 32 KB Flash, 1 KB EEPROM, 2 KB RAM, integrated CAN 2.0B controller, dual UARTs (one LIN-capable), SPI, I²C, and 10-bit ADC with up to 16 channels - deployed in automotive body control modules for LIN/CAN gateway functions.

For engineers reviewing the STM8S207S6T6CTR datasheet, STM8S207S6T6CTR pinout, STM8S207S6T6CTR application, or STM8S207S6T6CTR equivalent, key selection considerations include CAN/LIN coexistence capability, SWIM single-wire debug support, 2.95–5.5 V wide supply range, 16-channel analog input multiplexing, and LQFP44 package compatibility with industrial temperature-grade operation.

Technical Context

The STM8S207S6T6CTR implements a 3-stage pipelined Harvard-architecture core delivering up to 20 MIPS at 24 MHz with zero wait states below 16 MHz. Its clock system integrates user-trimmable 16 MHz RC, low-power 128 kHz RC, and external crystal/resonator support with clock security monitoring.

Peripheral integration includes a beCAN 2.0B controller supporting 1 Mbit/s active operation, two UARTs (UART1 with LIN master mode and automatic resynchronization, UART3 with synchronous clock output), and a 10-bit ADC with configurable sampling time and hardware-accelerated data alignment - all accessible via dedicated DMA channels and interrupt vectors.

FAQ

What is the maximum operating frequency and voltage range for the STM8S207S6T6CTR?

The STM8S207S6T6CTR operates at up to 24 MHz with zero wait states at frequencies ≤16 MHz. Its supply voltage range is 2.95 V to 5.5 V, supporting direct connection to standard 3.3 V and 5 V rails without level-shifting. The device maintains full functionality across this range, including ADC accuracy and CAN timing compliance, as verified in ST's electrical characteristics tables (DocID14733 Rev 13, Sections 10.3.1–10.3.3).

Does the STM8S207S6T6CTR support LIN communication, and how is it implemented?

Yes, the STM8S207S6T6CTR supports LIN 2.1-compliant communication via UART1, which includes LIN master mode with automatic baud rate detection, sync break generation, and checksum verification. It handles both master and slave roles without external hardware assistance, and its SWIM interface allows runtime LIN frame inspection during development. This capability is documented in Section 4.14.1 and Table 4 of the datasheet.

How many I/O pins does the LQFP44 package provide, and what are their drive capabilities?

The LQFP44 package provides 37 usable I/O pins across five ports (PA–PE), with 18 configured as high-sink outputs capable of driving up to 20 mA per pin. All I/Os feature current-injection immunity, configurable pull-up/pull-down resistors, and software-selectable slew rate. Pin functions are detailed in Table 6 (Pin Description) and Figure 6 (LQFP44 pinout) of the datasheet.

Is there hardware support for debugging and programming in-circuit?

Yes, the STM8S207S6T6CTR integrates a Single Wire Interface Module (SWIM) that enables full-speed in-circuit debugging and programming using only one dedicated pin (SWIM). It supports breakpoints, watchpoints, register inspection, and flash memory operations via ST-LINK/V2 or compatible debuggers - eliminating the need for JTAG headers and reducing PCB complexity.
