Product details
Overview
STM8S005C6T6TR from STMicroelectronics is a value-line 8-bit microcontroller featuring a Harvard-architecture STM8 core, 32 Kbytes of Flash memory, 128 bytes of true data EEPROM, and a 10-bit ADC with up to 10 channels-designed for cost-sensitive industrial control and appliance motor management applications.
For engineers reviewing the STM8S005C6T6TR datasheet, STM8S005C6T6TR pinout, STM8S005C6T6TR application, or STM8S005C6T6TR equivalent, key selection criteria include its 16 MHz max CPU frequency, LQFP48 package with 38 I/Os (16 high-sink), integrated SWIM debug interface, and support for UART, SPI, and I²C in a single-chip solution.
Technical Context
The STM8S005C6T6TR implements an advanced 3-stage pipeline STM8 core with nested interrupt controller supporting 32 interrupts and up to 37 external vectors. Its clock system integrates four master sources: 16 MHz user-trimmable RC, 128 kHz low-power RC, crystal resonator, and external clock input-with clock security monitoring and flexible peripheral gating.
Analog and timing subsystems include a 10-bit ±1 LSB ADC with scan mode and analog watchdog, two 16-bit general-purpose timers (TIM2/TIM3) with capture/compare/PWM, and TIM1-an advanced 16-bit timer with dead-time insertion, 3 complementary outputs, and synchronization capability-enabling precise motor phase control.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM8S003F3P6 | 20 Kbytes Flash, 1 Kbyte RAM, LQFP20 package, no TIM1 advanced timer | Limited to simpler control tasks (e.g., fan speed only); lacks dead-time insertion and complementary outputs | Select when BOM cost is primary constraint and motor control complexity is low |
| STM8L051F3P6 | Ultra-low-power architecture, 8 Kbytes Flash, 1.65–3.6 V operation, no 16 MHz RC | Optimized for battery-powered sensing; incompatible with 5 V systems and high-speed UART/LIN | Choose for sub-μA sleep current in energy-harvesting nodes-not for 5 V industrial mains-powered designs |
Compared with STM8S005C6T6TR, the STM8S003F3P6 reduces Flash and timer capability for lower cost, while the STM8L051F3P6 trades performance and voltage range for extreme low-power operation-neither matches the balanced feature set for 5 V industrial motor control.

FAQ
What is the maximum operating voltage and temperature range for STM8S005C6T6TR?
The STM8S005C6T6TR operates from 2.95 V to 5.5 V and is qualified for the industrial temperature range of –40 °C to +85 °C. Absolute maximum ratings specify VDD up to 6.0 V, but sustained operation above 5.5 V risks permanent damage. Thermal derating is not required within this range under specified PCB layout conditions.
Does STM8S005C6T6TR support in-circuit programming without removing the chip from the board?
Yes-it features an embedded Single-Wire Interface Module (SWIM) that enables full-speed programming and non-intrusive debugging using only one dedicated pin (SWIM) and ground. No external programmer hardware is needed beyond a SWIM-compatible debugger (e.g., ST-LINK/V2), and no bootloader code is required in Flash.
How many independent PWM channels can be generated simultaneously on this MCU?
The STM8S005C6T6TR supports up to 10 independent PWM outputs: TIM1 provides 4 complementary PWM channels (with dead-time), TIM2 and TIM3 each offer 2+3 CAPCOM channels (totaling 10 configurable OC/PWM outputs), and TIM4 adds one 8-bit PWM channel-subject to pin remapping constraints in LQFP48.
Is the data EEPROM truly wear-levelled, or does it require manual management?
The 128-byte data EEPROM is implemented as a dedicated memory block with hardware-managed erase/write sequencing. It guarantees 100,000 write/erase cycles per byte without software wear-leveling-users write directly to EEPROM addresses using standard ST library functions (e.g., FLASH_EraseByte, FLASH_ProgramByte).
