It carries 16 KB of Flash program memory, 4K x 8 of RAM, and 2K x 8 of EEPROM — enough for a moderate touch-sensing firmware stack without external storage. The headline feature is the integrated ProxSense peripheral, which handles capacitive touch and proximity detection directly, so you skip the separate touch controller IC and the I²C bus traffic that goes with it. ## Supply and power — single-cell friendly The 1.65 V to 3.6 V supply range lets this MCU run directly from a single Li-ion or LiFePO4 cell without a boost regulator. At the low end, 1.65 V keeps the core alive and the ProxSense scanner active even as the battery nears depletion.","metaTitle":"ST STM8TL52F4P6TR 8-bit MCU, 16 MHz, 16 KB Flash, TSSOP-20","metaDescription":"STMicroelectronics STM8TL52F4P6TR 8-bit MCU with 16 MHz core, 16 KB Flash, 4K x 8 RAM, 2K x 8 EEPROM, ProxSense touch peripheral. -40°C to 85°C, 1.65-3.6 V.
