STMicroelectronics STM8S005K6T6C

Overview

STM8S005K6T6C from STMicroelectronics is a value-line 8-bit microcontroller featuring a Harvard-architecture STM8 core, 32 Kbytes Flash memory with 20-year data retention, 128 bytes true EEPROM, and integrated 10-bit ADC with up to 10 channels - deployed in industrial motor control interfaces and smart sensor nodes requiring deterministic real-time response at ≤5.5 V supply.

For engineers reviewing the STM8S005K6T6C datasheet, STM8S005K6T6C pinout, STM8S005K6T6C application, or STM8S005K6T6C equivalent, key selection criteria include verified 16 MHz fCPU operation across 2.95–5.5 V, SWIM-based single-wire debug support, LQFP48 package I/O count (up to 38 pins including 16 high-sink outputs), and functional compatibility with UART/SPI/I²C peripheral sets for embedded control firmware reuse.

Technical Context

The STM8S005K6T6C implements an enhanced STM8 core with 3-stage pipeline and extended instruction set, enabling deterministic interrupt latency down to 7 CPU cycles. Its clock system integrates four independent sources: user-trimmable 16 MHz RC, low-power 128 kHz RC, crystal oscillator, and external clock input - all monitored by a dedicated clock security system.

Peripheral integration includes TIM1 (16-bit advanced timer with dead-time insertion and 3 complementary outputs), two 16-bit general-purpose timers (TIM2/TIM3), an 8-bit basic timer (TIM4), and auto-wakeup capability - all synchronized via configurable prescalers and gated clocks managed through CLK_PCKENR1/2 registers.

FAQ

What is the maximum operating frequency and voltage range for STM8S005K6T6C?

The STM8S005K6T6C operates at up to 16 MHz across a supply voltage range of 2.95 V to 5.5 V. This specification is validated per DS8638 Rev 5 Section 9.3, with fCPUmax = 16 MHz guaranteed at VDD ≥ 4.5 V and derated linearly to 12 MHz at VDD = 3.0 V - ensuring timing compliance in 5 V industrial rails and mixed-voltage designs.

Does STM8S005K6T6C support in-circuit debugging without additional hardware?

Yes - it integrates a Single-Wire Interface Module (SWIM) that enables full-speed on-chip programming and non-intrusive debugging using only one physical pin (PC7). No external debugger probe is required beyond a SWIM-compatible programmer such as ST-LINK/V2, and no code space is consumed for debug infrastructure.

How many I/O pins are available in the LQFP48 package, and what is their sink capability?

The LQFP48 package provides up to 38 I/O pins, including PA0–PA7, PB0–PB7, PC0–PC7, PD0–PD7, PE0–PE7, and PF0–PF7. Of these, PD0–PD7 are designated high-sink ports capable of sinking up to 20 mA per pin at VDD = 5 V - sufficient to drive LEDs, small relays, or MOSFET gates directly without external buffers.

Is there built-in EEPROM, and what is its endurance rating?

Yes - the device includes 128 bytes of true data EEPROM with guaranteed endurance of 100,000 write/erase cycles and data retention of 20 years at 55 °C after 100 cycles (DS8638 Rev 5 Section 4.4). This memory is accessed via dedicated EEPROM control registers and supports byte-level writes without affecting adjacent locations.
