STMicroelectronics ST7LITE2 User Manual
The ST7LITE2 is an 8‑bit microcontroller from the ST7 family with 8 Kbytes of single‑voltage flash, 384 bytes of RAM and 256 bytes of data EEPROM. It supports a range of on‑chip peripherals such as SPI, a 10‑bit ADC, multiple timers, and a debug module, and can operate from 2.4 V to 5.5 V.
The manual covers pin descriptions for the 20‑pin DIP and SO packages, register and memory maps, power‑saving modes (Halt, Active‑Halt, Wait, Slow, Auto Wake‑Up), electrical characteristics, and revision history. It also provides guidance on programming, reset management, and interrupt handling.
