Datasheet

The STM8L001 ultra-low-power microcontroller from STMicroelectronics targets cost-conscious applications, by combining ST’s highly efficient 8-bit STM8 core with essential and effective peripherals, in the compact, low-pin-count SO-8 outline.

The microcontroller provides essential features for basic sensing, communication, and control, including two comparators, SPI, I2C, and UART interfaces, and one 8- and two 16-bit timers. 8Kbytes of flash memory and 1.5Kbytes of RAM provide cost effective code and data storage, and up to 2Kbytes of the flash memory can be assigned to act as data EEPROM.

A flexible internal clock system, adjustable from 32kHz to 16MHz, saves component count and simplifies board design.

The STM8L001 delivers a competitively priced device with suitable performance for applications such as industrial sensors, lighting equipment, battery chargers, toys, e-Bikes, access cards, PC accessories, printer cartridges, and other cost- and power-sensitive smart products.

The up to six user I/Os allow engineers to take full advantage of the STM8L001’s optimised specification. ST’s ultra-low-power technologies ensure frugal operation in all modes, cutting current to as little as 300nA in halt mode to maximise the lifetime of battery-powered devices.

The STM8L001 is also flexible, operating from 1.8-3.6V, and fully specified from -40°C to 125°C to ensure reliability even in harsh conditions.

The STM8L001J3 is in production now in the SO-8 package, priced from $0.21 for orders of 10,000 pieces.
