STM32L100 Value Line

The STM32L1 series now hosts an entry level line, the STM32L100

The latest addition to ST’s STM32 L1 series, the STM32L100, is the perfect fit for applications that require a minimum processing power and ultra-low power consumption, all at a budget price.

The STM32L100 comes with a real-time clock, 16-bit timers, communication interfaces (SPI, I²C, USART, USB), analog peripherals, including a 12-bit ADC, and a LCD driver (up to 8x28 segments).

The STM32L100 Value line operates from 1.8 to 3.6 V and is available in the -40 to +85 °C temperature range.

All STM32 L1 series share the same architecture with the same memory mapping and are fully pin-to-pin compatible.

Wondering what’s new with the STM32L100x6/8/B-A MCUs?

•Overall power consumption improved in dynamic and static.
•RTC V2.0 to catch up with L1 Serie with Calendar function and  Sub-second counting for accurate synchronization with an external clock
• RAM increased to 16KB in STM32L100RB-A
• Same package, same pinout and software-compatible.
• Cost effectiveness
