Product details

Active 8-bit MCU with 64 KB flash and 24 MHz core

The STM8S207K8T6CTR: It packs 64 KB of program flash, 6 KB of SRAM, and 1 KB of EEPROM on a single die — enough headroom for a mid-range control application without external memory. The 24 MHz clock rate sets the throughput ceiling for real-time loops like sensor fusion or motor commutation; the internal oscillator means no external crystal is needed for the core timing.

Peripheral set and I/O for control and communication

25 general-purpose I/O lines are available in the 32-LQFP (7x7 mm) package — enough for a keypad, a small LCD segment driver, and a handful of sensor interrupts. On-chip connectivity includes I²C, SPI, UART/USART, LIN, and IrDA — the UART handles RS-232 or RS-485 via an external transceiver, while LIN suits automotive body-node buses. The brown-out detect and POR circuits keep the core from running on a marginal supply.

The part is RoHS3 compliant (lead-free, no restricted substances beyond the exemption list). The tape-and-reel packaging (Cut Tape also available) suits automated pick-and-place assembly.

The surface-mount package is moisture-sensitive; store the reels in a dry cabinet or bake before reflow if the moisture-barrier bag is breached.

Frequently asked questions

What is the closest functional alternative to STM8S207K8T6CTR?

The STM8S207C6T6TR is a close peer — same 24 MHz core, same 64 KB flash, same serial interfaces. The main difference is I/O count: 38 I/O and 10x10-bit ADC on the C6 variant versus 25 I/O and 7x10-bit ADC on the K8. If your BOM uses all 25 I/O and 7 ADC channels, the C6 is a drop-in replacement only if the extra pins are left unconnected or reconfigured in firmware.
