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.

Questions answered in these manuals
What are the power saving modes available?
The device supports five modes: Halt, Active-Halt, Wait, Slow, and Auto Wake Up From Halt.
From: STMicroelectronics ST7LITE2 8-Bit Microcontroller Datasheet
What is the operating voltage range?
The operating supply voltage is between 2.4V and 5.5V.
From: STMicroelectronics ST7LITE2 8-Bit Microcontroller Datasheet
How can 13-bit resolution be achieved with the ST7LITE2 ADC?
13-bit resolution is achieved by using the internal amplifier to amplify small signals, allowing the minimum measurable signal to be 0.6103mV at 5V.
From: STMicroelectronics AN1830 ST7LITE2 ADC Accuracy Application Note
What is the purpose of the amplifier offset?
The offset is introduced to keep the driver transistor in the active region and avoid nonlinearity in the transfer curve around 0V input.
