Product details

What this 8-bit MCU brings to a field-swap or new build

The STMicroelectronics STM8S207C8T3 is an 8-bit MCU from the STM8S series, built around the STM8 core and clocked at 24 MHz. The 48-LQFP package gives you 38 I/O pins, so you can wire up a keypad, a small display, and a handful of sensors without multiplexing.

Peripheral set — what you can hook up without extra chips

The 10-channel 10-bit ADC covers analog inputs like thermistors, potentiometers, or current-sense resistors. Internal oscillator means you can skip the external crystal for many applications, saving two pins and a couple of passives. If you are replacing a failed board in the field, these integrated peripherals reduce the number of external components you need to carry in your kit.

There is no last-time-buy deadline to manage, no end-of-life notice to track.

Frequently asked questions

What is the difference between STM8S207C8T3 and STM8S207C8T6?

The suffix T3 versus T6 typically indicates a different temperature grade or packaging option within the same STM8S207C8 family. Check the specific datasheet for the T6 variant's temperature rating to confirm the difference.

What is the programming interface for STM8S207C8T3?

The STM8S series uses a single-wire interface (SWIM) for programming and debugging. It requires only one pin plus ground and supply, which makes it straightforward to program on a populated board or in a field-swap scenario with a simple adapter.

Is STM8S207C8T3 equivalent to STM32L151CBU6A?

No, these are not equivalents. The STM8S207C8T3 is an 8-bit STM8 core part. They are not pin-compatible or software-compatible.
