64 KB Flash, 24 MHz — the industrial 8-bit workhorse
The STMicroelectronics STM8S007C8T6TR is an 8-bit STM8S-series microcontroller built around the STM8 core, clocked at 24 MHz.
24 MHz core — timing budget for real-time control
At 24 MHz, the STM8S007C8T6TR delivers enough instruction throughput for PWM generation, UART communication at standard baud rates, and interrupt-driven sensor polling. If you need precise timing for a motor commutation loop or a LIN bus node, the 24 MHz clock gives you a 41.7 ns instruction cycle — adequate for the control loops this class of part targets.
Memory layout — Flash, RAM, and EEPROM sizing
The 6 KB of RAM is the hard limit for runtime variables, stack depth, and DMA buffers — enough for a few hundred sensor readings or a small display frame buffer but not for large image processing. The 128 bytes of EEPROM is useful for storing calibration constants, unit IDs, or configuration parameters that survive a power cycle; it saves adding an external serial EEPROM for small persistent data.
The 10-bit ADC with 16 channels covers multi-sensor acquisition without an external ADC. The brown-out detect resets the MCU cleanly when the supply dips, which is critical in noisy industrial or automotive environments where a glitch could corrupt the program counter.
Package and footprint — 48-LQFP, 7x7 mm
The 38 I/O pins leave headroom for a parallel LCD bus, multiple sensor interfaces, and a few spare GPIOs for board-level signalling. The Tape & Reel variant (TR suffix) is the production-friendly format for pick-and-place assembly.
Lifecycle status — active production, no EOL concern
The ROHS3 compliance is confirmed.
For a production BOM line requiring the STM8S007C8T6TR, the active lifecycle means supply continuity without the premium pricing that accompanies NRND or EOL parts.
