Low-power 8-bit MCUs

13 October 2010 DSP, Micros & Memory

STMicroelectronics has extended its STM8L EnergyLite low-power microcontroller family with new devices offering enhanced features such as larger program/data memory, high-accuracy time-keeping, a controller for as many as16 touch-sensitive keys, and support for 128-bit AES encryption. The three variants of the STM8L family are the STM8L151, the STM8L152 and the STM8L162, each of which has 64 KB of Flash memory, effectively doubling the maximum program/data memory available to developers using the 8-bit STM8L family. SRAM density is also increased to 4 KB. The STM8L152 also adds an enhanced LCD controller that supports larger segments. Common to all the new devices is an enhanced real-time clock (RTC) module offering sub-second accuracy, as well as support for calibration, enabling increased precision in applications requiring time stamping and accurate synchronisation.
