ST公司的STM32L152是超低功耗,高数据安全性,高效能的ARM Cortex-M3微控制器系列芯片。低功耗运行模式电流为10.4μA，工作电压为1.8～3.6 V。在32 MHz频率下的处理性能达到33 DMOPS(最大值)，可提供出色的计算性能和对事件的卓越系统响应，同时可应对动态和静态功率限制的挑战。主要应用在低功耗医疗和手提设备,工业控制和用户接口,PC外设,游戏和GPS设备,有线和无线传感器,告警系统和公用表.本文介绍了STM32L152主要特性,方框图,以及STM32L152-EVAL评估板主要特性,电路图和元件布局图.
The ultralow power STM32L15xxx incorporates the connectivity power of the universal serial bus (USB) with the high-performance ARM Cortex™-M3 32-bit RISC core operating at a 32 MHz frequency, a memory protection unit (MPU), high-speed embedded memories (Flash memory up to 128 Kbytes and RAM up to 16 Kbytes), and an extensive range of enhanced I/Os and peripherals connected to two APB buses. All devices offer a 12-bit ADC, 2 DACs and 2 ultralow power comparators, six general-purpose 16-bit timers and two basic timers, which can be used as time bases. Moreover, the STM32L15xxx devices contain standard and advanced communication interfaces: up to two I2Cs and SPIs, three USARTs and a USB. They also include a real-time clock and a set of backup registers that remain powered in Standby mode. Finally, the integrated LCD controller has a built-in LCD voltage generator that allows you to drive up to 8 multiplexed LCDs with contrast independent of the supply voltage.
The ultralow power STM32L15xxx operates from a 1.8 to 3.6 V power supply (down to 1.65 V at power down) with BOR and from a 1.65 to 3.6 V power supply without BOR option.It is available in the -40 to +85 °C temperature range. A comprehensive set of power-saving modes allows the design of low-power applications.
