At 24 MHz, the STM8 pipeline executes most instructions in a single clock cycle, giving a throughput of roughly 24 MIPS. That is enough headroom for a 20 kHz PWM loop with a few hundred microseconds left for communications and housekeeping. ## Memory sizing: Flash, RAM, and EEPROM 64 KB of Flash is sized for mid-complexity firmware — bootloader, application code, and a modest parameter table. The 6 KB RAM handles a few communication buffers and a stack for nested interrupts without overflow. The 1.5 KB EEPROM is useful for calibration constants and fault logs that survive power loss, avoiding the need for an external serial EEPROM. ST lists the STM8S207R8T3 as Active. For production programs that need a stable 8-bit MCU through the next several years, this is a safe choice without the supply-chain gymnastics of an EOL part.","metaTitle":"ST STM8S207R8T3 8-bit MCU, 24 MHz, 64 KB Flash, 64-LQFP","metaDescription":"STMicroelectronics STM8S207R8T3 8-bit STM8 MCU runs at 24 MHz with 64 KB Flash, 6 KB RAM, 1.5 KB EEPROM.

Both share the same 24 MHz core, pin-compatible 64-LQFP package, and peripheral set. The R8 variant is the right pick when the firmware image exceeds 32 KB or you need the additional RAM for larger data buffers."},{"question":"How to program STM8S207R8T3?","answer":"Programming is done via the SWIM (Single Wire Interface Module) debug interface, which uses a single pin for communication. ST offers the ST-LINK/V2 programmer or third-party tools that support SWIM.
