STMicroelectronics STM8S007C8T6TR

Overview

STM8S007C8T6TR from STMicroelectronics is an 8-bit value-line microcontroller featuring a Harvard-architecture STM8 core, 64 Kbytes Flash, 128 bytes true data EEPROM, 6 Kbytes RAM, 10-bit ADC (16-channel), two UARTs (one LIN-capable), SPI, I²C, and three 16-bit timers including an advanced control timer with dead-time insertion and complementary outputs. It operates from 2.95–5.5 V and targets cost-sensitive industrial control and appliance motor management.

For engineers reviewing the STM8S007C8T6TR datasheet, STM8S007C8T6TR pinout, STM8S007C8T6TR application, or STM8S007C8T6TR equivalent, key selection criteria include its 24 MHz max CPU frequency with zero wait states ≤16 MHz, high-sink I/O capability (16 pins), SWIM single-wire debug interface, and integrated clock security system with multiple low-power modes.

Technical Context

The STM8S007C8T6TR implements a 3-stage pipelined Harvard architecture core with extended instruction set and nested interrupt controller supporting 32 interrupts and up to 37 external vectors. Its clock system integrates user-trimmable 16 MHz RC, low-power 128 kHz RC, crystal oscillator, and external clock input, all monitored by a clock security system.

Peripheral integration includes TIM1 (advanced 16-bit timer with 4 CAPCOM channels, 3 complementary outputs, dead-time insertion), TIM2/TIM3 (general-purpose 16-bit timers), TIM4 (8-bit basic timer), auto-wakeup timer, window/independent watchdogs, and dual UARTs-one supporting LIN 2.1 master/slave with automatic resynchronization.

FAQ

Does STM8S007C8T6TR support in-system programming via SWIM?

Yes. The device features a Single Wire Interface Module (SWIM) that enables full in-circuit programming, debugging, and memory access using only one dedicated pin (SWIM). No external bootloader is required, and programming can be performed at voltages from 2.95 V to 5.5 V with standard ST-LINK/V2 or compatible debuggers.

What is the maximum operating frequency and associated voltage requirement?

The STM8S007C8T6TR achieves a maximum CPU frequency of 24 MHz at VDD ≥ 4.5 V. At 3.3 V, the maximum guaranteed fCPU is 16 MHz with zero wait states; operation above 16 MHz at 3.3 V is not specified and may result in timing violations or instability.

How many I/O pins support high-sink capability, and what is the rated current?

Exactly 16 I/O pins (designated as "high sink" in the datasheet) support 20 mA sink current each at VDD = 5 V. These pins are distributed across ports A, B, C, D, and E - enabling direct driving of LEDs, small relays, or MOSFET gate resistors without external buffer stages.

Is there hardware support for LIN 2.1 communication, and which UART implements it?

Yes. UART3 implements full LIN 2.1 compliance, including master and slave modes, automatic resynchronization, break detection, and checksum calculation. This allows seamless integration into automotive body networks or appliance sub-buses without software bit-banging or external transceivers.
