FAQ:
What is the STM8S007C8T6 and its key specifications?
The STM8S007C8T6 is an 8‑bit microcontroller from STMicroelectronics based on the high‑performance STM8 core at up to 24 MHz. It provides 64 KB of Flash program memory, 6 KB of SRAM, and 2 KB of true data EEPROM. On‑chip peripherals include a 10‑bit ADC, an advanced motor‑control timer (TIM1) with 3 complementary PWM pairs, a full CAN 2.0B controller, and USART/SPI/I2C interfaces. Housed in an LQFP‑48 package, it provides 38 I/O pins and operates over ‑40 °C to +85 °C. Part of the STM8S Value line, it delivers a robust CAN‑enabled, motor‑control solution in a cost‑effective platform that is pin‑compatible with the popular STM8S207 series.
How does the STM8S007C8T6 differ from the STM8S207C8T6? Which one should I choose?
Both are pin‑compatible and share the same core, memory (64 KB Flash, 6 KB SRAM, 2 KB EEPROM), CAN 2.0B, and TIM1 with three complementary PWM pairs. The STM8S007C8T6 is part of the Value line, while the STM8S207C8T6 belongs to the Performance line. The S207 may offer slightly better analog performance (e.g., more ADC channels or tighter internal oscillator tolerance) and a wider set of qualification data, but for most applications the S007 delivers identical digital functionality and CAN connectivity at a more attractive price. Choose the S007 when CAN and motor control are the main requirements; choose the S207 if you need the maximum analog channel count or rely on performance‑line specific parameters.
Does the STM8S007C8T6 have a CAN bus interface?
Yes, it integrates a full beCAN 2.0B active controller. It supports both standard 11‑bit and extended 29‑bit identifiers, data rates up to 1 Mbit/s, and includes 3 transmit mailboxes and 2 receive FIFOs. This makes the chip well‑suited for automotive and industrial CAN networks in cost‑sensitive designs.
Can the STM8S007C8T6 drive a brushless DC motor directly?
Yes. The advanced timer TIM1 provides 3 complementary PWM pairs with programmable dead‑time insertion and a break input. This allows the MCU to directly control a three‑phase inverter or a BLDC motor half‑bridge without external dead‑time logic. It is widely used in fans, pumps, power tools, and home appliances.
What are the ADC specifications and how many analog channels does the STM8S007C8T6 have?
It features a 10‑bit successive‑approximation ADC. In the LQFP‑48 package, typically 10 external analog input channels are available, depending on which digital functions are enabled on shared pins. The ADC can also measure an internal voltage reference and can be triggered by TIM1 for synchronized motor‑current sensing.
How much memory does the STM8S007C8T6 have?
It provides 64 KB of Flash program memory, 6 KB of SRAM, and 2 KB of true data EEPROM. This generous memory configuration comfortably supports CAN protocol stacks, motor‑control algorithms, and complex application logic.
What package and I/O count does the STM8S007C8T6 use?
It comes in an LQFP‑48 package (7 mm × 7 mm, 0.5 mm lead pitch) and provides 38 general‑purpose I/O pins. This package offers a good balance between compact size and rich connectivity for mid‑complexity embedded designs.
Can the STM8S007C8T6 be powered directly from 5 V?
Yes, it is a true 5 V‑capable microcontroller. The operating voltage range is 2.95 V to 5.5 V, so you can power it directly from a standard 5 V rail, USB, or a loosely regulated supply. All I/O pins are 5 V tolerant, which simplifies interfaces with legacy TTL and CMOS logic.
How to program and debug the STM8S007C8T6?
Programming and debugging use the single‑wire SWIM interface. A low‑cost ST‑LINK/V2 is the standard tool. Firmware can be developed with STVD + Cosmic C or the open‑source SDCC compiler, and ST provides standard peripheral libraries to speed up development.
What are the most typical applications of the STM8S007C8T6?
Thanks to its CAN connectivity, three‑phase motor‑control timer, generous memory, and 5 V operation, the STM8S007C8T6 is widely used in automotive body electronics, industrial CAN nodes, motor drives (fans, pumps, power tools), home appliances, and building automation. It is an especially strong fit for cost‑sensitive distributed control systems that require reliable CAN communication and direct BLDC motor drive capability.
