ST STM8L15xxx超低功耗8位MCU开发方案

ST公司的STM8L15xxx是超低功耗8位MCU系列,采用先进的STM8内核,动态功耗为192 μA/MHZ,16MHz CPU时钟的性能高达16 MIPS, 工作电压从1.8 V 到3.6 V (低至1.65 V ),多达32KB嵌入闪存程序存储器,主要用在医疗和手提设备,PC外设,游戏机,GPS,告警系统,有线和无线传感器.本文介绍了STM8L15xxx主要特性,方框图, 时钟树框图和超低功耗STM8L15LPBOARD演示板主要特性,详细电路图.

The STM8L15xxx devices are members of the STM8L Ultralow power 8-bit family. They are referred to as medium-density devices in the STM8L15xxx reference manual (RM0031) and in the STM8L Flash programming manual (PM0054). They provide the following benefits:

● Integrated system

– Up to 32 Kbytes of medium-density embedded Flash program memory

– 1 Kbyte of data EEPROM

– Internal high speed and low-power low speed RC.

– Embedded reset

● Ultralow power consumption

– 192 μA/MHZ (dynamic consumption)

– 1 μA in Active-halt mode

– Clock gated system and optimized power management

– Capability to execute from RAM for Low power wait mode and Low power run mode

● Advanced features

– Up to 16 MIPS at 16 MHz CPU clock frequency

– Direct memory access (DMA) for memory-to-memory or peripheral-to-memory access.

● Short development cycles
