The STM8L162R8/M8 is an 8-bit ultralow power MCU from STMicroelectronics with 64KB flash, 2KB data EEPROM, RTC, AES, LCD, timers, USART, I2C, SPI, ADC, DAC, COMPs, etc.
This document is a production datasheet for the STM8L162R8 and STM8L162M8, which are 8-bit ultralow power microcontrollers (MCUs). The devices feature an advanced STM8 core with a maximum frequency of 16 MHz, 64 KB of Flash program memory, and 2 KB of data EEPROM with ECC and RWW capabilities.
Key features include five low power modes, an ultralow leakage current of 50 nA per I/O, and fast wakeup from Halt mode in 5 µs. The microcontrollers support various communication interfaces such as two SPIs, Fast I2C, and three USARTs, along with hardware AES encryption acceleration and a 12-bit ADC capable of up to 1 Msps.
