Key datasheet specifications and the closest alternatives, ranked by parametric similarity and grounded in the manufacturer datasheet.

01 — Overview

This ST Microelectronics datasheet covers the STM8S001J3, an 8-bit MCU in the STM8S family with SO8N packaging. It details electrical specs and functional blocks for parts ending in J3M3TR or J3M3. Key parameters include a 16 MHz core, 8-Kbyte Flash memory, 128-byte EEPROM, and 10-bit ADC. Operating voltage spans 2.95 V to 5.5 V. The device features three timers (one advanced control, two general purpose), UART, SPI up to 8 Mbit/s, and I2C up to 400 Kbit/s. It supports low-power modes like active-halt and halt, plus watchdog timers and an internal reference voltage measurement.
